Product introduction
The imported vacuum ball valve produced by Breer can be driven by manual, electric or pneumatic. The connection method can be flange quick-release, looper flange, the structure can be straight-through, three-stage, and the sealing structure can be PTFE, NBR , Fluorine rubber, PPL, pressure range PN16MPa-6.4MPa, nominal diameter is DN10-200mm, the material can choose carbon steel, 304,316, titanium alloy steel and so on. Because the valve is used in a very wide range, the same valve has different combinations in different situations and working conditions.
Product Details
The imported vacuum ball valve is straight-through and sealed by a spherical surface, so it can be used in both vacuum and low pressure conditions, and can be installed at any position to connect or cut off the medium flow in the vacuum system pipe road. Used in vacuum, dairy, wine, bioengineering, food, pharmaceutical, beverage, cosmetics and chemical fields. Optional feedback signal device and electric valve positioner
The role of high vacuum ball valve in vacuum system:
1. Open and close the gas path. When valve 1 and valve 4 are closed and valve 2 is opened, the mechanical vacuum pump III evacuates container I, and the airflow flows through the pre-vacuum extraction line. When valve 2 is closed and valve 4 is opened, the mechanical pump can Evacuate the diffusion pump separately; when valve 1 and valve 4 are opened at the same time, the diffusion pump and mechanical pump can work at the same time to evacuate the container, and the airflow flows through the diffusion pump. It can be seen that the role of the valve in this operation is to open and close the gas path and change the flow path of the air flow.
2. Control the size of the air flow and adjust the vacuum. In Figure 1, adjust the opening angle of the valve cover of the valve 1 to adjust the amount of air flow through the pipeline; close the valve 2 and valve 4, and the mechanical pump can be supplied through the air release valve 3. The inlet of III is released into the atmosphere; the vacuum degree in the container can be adjusted through the air release valve 5.
3. Quantitative inflation, there is a small hole of a certain volume on the plunger of the glass valve. When the small hole turns to the right and communicates with the high-pressure gas cylinder, the small hole can be filled with high-pressure gas; when it turns to the left and communicates with the vacuum container , Put the volume of high-pressure gas into the container, so it plays a role of quantitative inflation.
There are many types of vacuum valves, which are usually classified according to their functions, structural types, driving methods, materials and applications.
[One] main performance:
① Leakage rate: valve body ≤1.3 × 10-9Pa.M3 / S;
② Pressure range: 1.3 × 10-7Pa ～ 6 × 105Pa;
③ Working medium: water, steam, acid and alkali.
④Working temperature: -30 ℃ ～ + 150 ℃.
⑤Installation position: Any.
⑥ Life: ≥50,000 times.
[Two] working principle: the valve rod is used to drive the valve ball to rotate 90o to achieve the purpose of switching.
[Three] product main features:
① The sealing structure is unique in design, and the leakage rate can reach <1 × 10-10Pa.M3 / S,
Changed the status of the ball valve can not meet the high vacuum, ultra high vacuum;
② Small switching torque, stable and reliable operation;
③ Compact structure, light weight, simple and beautiful appearance;
④ The modified valve can be used for both high vacuum and certain positive pressure.
⑥ Because the ball valve is fully conductive and can meet the requirements of ultra-high vacuum, it can also be applied to the accelerator vacuum system.
[Four] main parts material: ① valve body: stainless steel 304, 316L ② ball: 316L ③ seal: reinforced polytetrafluoroethylene
