Second, from the perspective of environmental application capability, the water resistance of pneumatic ball valve is excellent. Although the use of the device will be harmed in a humid or even waterlogged environment, it will not cause more serious harm due to electric sparks like hardware and electric tools. The pneumatic ball valve can operate in various adverse or even harsh working environments with the help of an internal combustion engine air pump.

Advantages and construction requirements of stainless steel corrugated compensator
The stainless steel corrugated compensator is composed of flange, guide cylinder, metal wave body, connecting pipe and other accessories. It belongs to a kind of compensator. The stainless steel corrugated compensator is composed of flange, guide cylinder, metal wave body, connecting pipe and other accessories. It belongs to a kind of compensator. The effective expansion and deformation of the bellows of its main body is used to absorb the axial, transverse and angular thermal deformation of the pipeline, which is also convenient for the installation and disassembly of the pipeline and can also absorb the impact of earthquake and subsidence on the pipeline. It is commonly used in modern plumbing.
Advantages of stainless steel corrugated compensator:
The plate box type limitable pipe compensator is one of the important parts for pipe installation. The compensator has the advantages of small size, convenient installation, small floor area, reduced labor intensity, labor, material and practicability. The expansion capacity is 60-120mm, no seepage, no leakage, no filler, good expansion performance, safe and reliable, and can save maintenance workload. At the same time, no expansion shaft can be set during installation to reduce the project cost. The compensator is novel and reasonable in structure, free of vulnerable parts, small in size, light in weight, and easy to install and transport. It is an ideal product for pipeline installation.
Design and construction requirements of stainless steel corrugated compensator:
1. The operating pressure of this product is below 1.6MPa, the operating medium: hot water, steam, gas, various oils, the temperature is the same as that of the pipeline, and the high-rise building is the best;
2. The maximum thrust of this product is 0.8-1.2T, and the fatigue life is 6500 times
3. This product can be widely used in overhead pipelines, trench pipelines and directly buried pipelines
4. Compensator steering bracket can be set or not
5. This product is only used for axial installation (straight pipe)
6. When this product is used for trench pipes, it is not necessary to build compensator wells
7. It is forbidden to ignite on the expansion box of the compensator during installation;
8. For this product, two wave pretension is 25mm - 30mm, four wave pretension is 50mm - 60mm;
9. Practice has proved that in the high-temperature water heating pipe network, a two wave expansion joint shall be set above 60m, a four wave expansion joint shall be set above 120m, and a two wave expansion joint shall be set within 30m of the steam pipeline according to the design standard.
