Pneumatic ball valve is a combination of pneumatic actuator and ball valve. It can replace manual operation, not only save a lot of manpower and material resources, but also control multiple ball valves at the same time. The pneumatic ball valve is relatively simple in structure, convenient in maintenance and high in relative safety. It is made of superior materials and properly used. Its service life can reach 1 million times. Pneumatic ball valve is evolved from plug valve. It has the same 90 degree rotation action, but the difference is that the cock body is a sphere with a circular through hole or channel through its axis. The proportion of the sphere and the passage opening should be such that when the sphere rotates 90 degrees, the inlet and outlet should be all spherical, so as to cut off the flow.

High quality rotary compensator should be selected to promote good development of the project
The application of maintenance free rotary compensator and rotary compensator products relies on the flexible packing in the packing chamber to stop sealing. During the application of the product, the packing will wear a little every time it rotates. When the wear reaches a certain value, the product will leak. The rotary compensator must stop the gas supply of the heat supply network pipeline, remove the packing from the flange, take part in a certain amount of packing, and then press the flange back to use; For the maintenance free rotary compensator, a set of springs is added above the packing compression flange. When the packing shows slight wear, it is compensated by the tension of the compression spring, so as to extend the leakage time of the product (the leakage time is delayed by 3-5 years). When the amount of wear exceeds the amount of spring tension compensation, it is only necessary to tighten the nut above the spring compression flange. There is no need to stop air for repair. There is no limit on the number of operations, and leakage is not easy to occur, thus greatly improving the social and economic benefits of gas supply units and gas users. The product will not leak after 5000 times of compensation under the pressure of 4.0Mpa, and the sealing effect is excellent.
The price of rotary compensator may be higher than that of other compensators of the same type. However, the rotary compensator is a kind of compensator with high cost and ratio. It greatly saves manpower and material resources in terms of product life and maintenance. In terms of long-term benefits, the purchase of rotary compensator is indeed the best choice.
With the increasing demand for compensators in the domestic market, the issue of how to promote the expansion of the compensator market has attracted more attention, which inevitably requires relevant consumer enterprises to improve the quality of production, move forward at the level, and pay more attention to the synergy of relevant departments, so as to promote the sustainability of their future market development.
Only when user demand increases can a product be sustainable. The same is true for compensators. When the market demand for the product increases, and when its output and quality have significantly improved compared with the past, it is time for the industry to develop rapidly and show prosperity. So how should people in the industry treat all this.
With the constant development of China's industry, the compensator product technology is also constantly developed, and the application scope is also constantly widened, and the corresponding product specifications will also be paid more and more attention. Therefore, we need to look forward to the future and discuss new specifications and systems that can be used in the future while fully applying existing specifications from time to time, so as to promote the development of compensator technology to a higher level and improve the degree and level of compensator products from time to time. In view of the development of the overall market today, the expansion of the compensator in the future will be carried out from time to time under the condition of constant expansion of demand. In the future, the compensator industry in China will be the competition of product technology innovation, safe production and quality, and product brands. The products will be developed in the direction of high technology, high parameters, strong corrosion resistance, and long life. Obviously, the compensator market will develop rapidly, It is inseparable from the quality control of consumer enterprises when manufacturing compensators. Water supply and drainage is undoubtedly a model in this regard. All products produced are strictly tested. These products have a positive impact on improving the competitiveness of the market and product level. Therefore, other domestic consumer enterprises should follow suit.
