Basic understanding about rising stem gate valve

The rising stem gate valve is usually made from cast or forged steel and is applied for crude oil, water, steam, gases and others nonabrasive media. A rising stem gate valve is designed with straight through bore type with rising stem, outside screw and yoke, bolted bonnet and stainless steel trim. The open and closed position of the valve is easily distinguished by the stem position. The wedge is replaceable without needing to remove the valve from the pipelines.

Rising stem gate valve is a kind of valve which prevents water flow and leakage when fully closed. When the valve is fully opened, it does not have any influence which disturbs water flow. Sealing is achieved by metal rings on the body and on the wedge. When the rings match with each other, they provide sealing. The wedge moves up and down by turning the revolving stem provided with a functional thread, enabling opening and closing of the valve.

With its rising feature, the user can detect from long distances whether the valve is open or closed and act immediately on the situation. Furthermore, the optional protection tube that is located at the top of the rising stem gate valve acts as a protection to the rising stem which prevents obstacles from contacting to the stem, and indicates whether the valve is fully opened or not. On the stem, accessories such as actuator, extension spindle, gearbox, chain wheel can be assembled.

The rising stem gate valve allows for two-way flow direction and used for closing or opening the medium flow. This type of valve can be installed in horizontal and vertical positions in the piping systems. It is widely applied in process industries such as Palm Oil and Refinery Plant, Food Industries, Petrochemical, Fire Protection System, Power Plant and Cooling System.

From the above statement, you may have a basic understanding about rising stem gate valve, and hope it could be of some help when you are choosing a gate valve. Or you can make a comparison with the non- rising type stem gate valve, then you can better know which type you want.

Automatic Toilet Paper Machine - intelligent benefit for business

No one can doubt that automation technology improved the production efficient. It is widely utilized in all aspect of life. This application of technology is also used in the toilet paper machine, which refers to the specialized processing production of toilet paper, we also call it toilet paper rewinding machine.

Automatic toilet winder takes big shaft paper as raw material to process and product toilet paper, since the big shaft paper is large in size and weight, a single person cannot get it placed into the rewinding machine, it needs at least two men to complete and is very trouble.

In order to overcome this difficulty, automatic toilet paper machine adopts horizontal paper frame on the back of the equipment, the base paper is straightly placed, and is transported by wide pneumatic double belt. Moreover, each roll of base paper is equipped with independent tensioning device, which is what we call the pneumatic paper feeding device.

In addition, automatic machine has alarm device, if broken paper phenomenon appears, the equipment will automatically stop and prompt the operating personnel. Toilet paper machine's main task is to rewind big shaft paper into small volume. Automation technology also has full application in rewinding process, the automatic paper machine is programmed by computer, the rewinding process of the raw paper is tight first and loose afterward, with its tension adjustable, , solving the problem of paper roll and paper core separates in the long time storage.

What’s more, automatic toilet paper equipment also has the function of automatically transfer paper tube, automatic delivery of finished goods and automatically winding paper, which greatly improve the production efficiency. Compared with semi-automatic rewinding machine, the fully automatic rewinding type has advantages of automatic trimming, glue and sealing function, by which not only production efficiency has been improved a lot, but also more accurate product is processed, making toilet paper more competitive on the exterior. Automatic rewinding machine can do embossing on both sides, and the end product is softer than single side embossing, and the design on both sides are consistent.

From the abovementioned analysis, I believe you will have better understanding about automatic toilet paper machine, so if you want to invest in toilet paper processing, I suggest you choose automatic toilet paper machine, which can produce all kinds of the toilet paper as required, and it has long service life to ensure the long-term production and processing. In a word, this device can benefit for your business

How to make the Machine save energy?

When seeking to maximize the energy performance of a machine drive, it is not enough simply to select the most energy efficient components. Correct dimensioning is critical, and complex interactions between components mean that the system as a whole must be carefully designed. Attention must also be paid to the control software, which plays a key role in availability and can therefore have a major impact on overall energy efficiency.

A large Toilet paper machine drive can consume up to 30 MW of power. With production running continuously for very long periods, even a relatively small incremental improvement in energy effi­ciency can produce considerable savings over the long term. Variable speed drives can produce remarkable increases in energy efficiency in certain applications by adjusting the speed of the motor to match the demands of the process. 

Another way to save energy for toilet paper machine is regeneration. In applica­tions with successive acceleration and deceleration cycles, regenerative drives produce electricity during the braking phases and feed it back to the network. If the machine can be liquid cooled, which can dramatically reduce the energy consumed in air condition­ing and cooling electrical rooms. 

Liquid cooling can decrease energy losses to the air within the electrical room by as much as 98 %. Other advantages of liquid cool­ing include a higher power density and compact drive cabinets, and higher pro­tection class enclosures offer increased options In order to optimize the energy efficiency of a toilet paper machine drive it is important to look at the system as a whole. This is because efforts to boost the efficiency of a single component in isolation may end up causing increased losses elsewhere. 

It is therefore crucial to understand how the type of power supply, VSD switching frequency and output voltage, and the motor design, affect total system effi­ciency. Achieving optimum energy effi­ciency involves much more than simply comparing the catalog values.

Development Opportunities for Toilet Paper Machine Suppliers

In recent years, new investment projects concerning household paper is increasing year by year, according to the statistics of Household Paper Professional Committee of the China Paper Association (hereinafter referred to as CNHPIA), in 2010 the new capacity of household paper is 415,000 t / a, and in 2011 a new capacity of 574,000 t / a. In 2012 the new capacity that has been put into production and plans to put into production is 1,512,500 t / a, the number in 2013 and after the project is also unabated. International and domestic toilet paper machine suppliers did their best to snatch the big cake of the Chinese market to develop core technology and marketing strategy around toilet paper, showing a "catch-me" posture.

Challenges and opportunities of a difficult time

Due to the slow economic recovery after the global financial crisis, the European debt crisis goes worse and worse, the toilet paper machine has weak market demand in Europe and the United States. On the contrary, sales of the imported paper machine surge in the Chinese market. International toilet paper machine suppliers start to shift their focus from U.S. and European markets to the emerging markets, especially in China. According to the statistics of CNHPIA in 2011, from 2011 to 2012 the new capacity of paper machine in china is 2.05 million t / a, accounting for about 60% of the global expected production capacity of 3.4 million t / a.

Take the road of independent innovation to win in the competition

The 21st century is an era of innovation, and technological innovation is the key point for tissue machine suppliers. Only by core technology and innovation can enterprises be invincible among multiple competitors. Compared with multinational companies, the domestic private enterprises are under limited financial resources and independent innovation is still in a smaller scope. However, based on the better understanding of local market, together with a fair competition environment created by the state in recent years, many private enterprises developed successfully relying on independent innovation and intellectual property.

Select the right equipment in accordance with local conditions

In facing of so much tissue machine suppliers, as well as their respective advantages of different models, how does manufacturers make choose? It is suggested that manufacturers should consider the factors of local energy cost, raw materials, and the development strategy of the enterprise to choose the toilet paper machine which suits their own development.

Accelerate structural adjustment, increase energy conservation

During the "12th Five-Year" period, China's paper producers are faced with important task of changing development patterns, accelerating structural adjustment, increasing energy conservation efforts, and taking the path of green development. In order to guide the development of the industry, the tissue machine equipped with a speed of 1,000 m / min or more high-speed is required according to the "12th Five-Year Plan.
