High total pressure exhaust valve QSP

Shanghai gold Yeah Valve Co., Ltd. sells [High total pressure exhaust valve QSP], is currently the largest "vent" online sales service providers. The company integrates high-quality full-pressure high-speed exhaust valve manufacturer, to provide pre-sale, sale and one-stop service. Company perennial with large cash reserves exhaust valves, valve selection to provide users with the principles of the role, structure, size, installation instructions, data downloads. High total pressure exhaust valve Principle on QSP: High total pressure total pressure of the high-speed exhaust valve by the body, the body, floats, float rods, valve, cover, piston, diaphragm and valve cover and other components exhaust valve, which is characterized by the hinge pin and pontoon float lever is rotated around the spindle, and thus float down control is achieved by opening and closing the valve lift that fall when the float (the body is filled with gas), the valve core rise, open the small valve opening, and close the small exhaust vent cap on the gas through the catheter into the hydraulic tank when the float rises in the buoyancy when the valve down to close small valve port, and open the drain vent gas cap on the hydraulic tank through the conduit, through atmospheric pressure relief, and when the float drops, the hydraulic cylinder filled with gas, large vent on the valve automatically closes. When the pump stops, water or air in the tube encounters a negative pressure inside the pipe, the intake air to ensure pipeline safety. High total pressure exhaust valve QSP Features: High total pressure exhaust valve is currently the most advanced cylinder exhaust valve on the structural performance completely beyond the ordinary high-speed (dual-port) composite exhaust valve and exhaust valve For the gas pipeline, either multistage water column, column and white, there is continuous high pressure without pressure can exhaust duct, not float on top of the exhaust port, card bad problem does not exist, a small amount of gas can be discharged through the pores, When gas injection pipeline can appear negative, anti-gas dyed and buffered water hammer boost, lifting the commissioning of the new pipeline risk, it is difficult to exhaust, reducing Chengshiguanwang tube rupture, drag energy saving, reducing pressure shocks, increase overall water supply system security and reliability. High total pressure exhaust valve QSP technical parameters: Nominal diameter DN (mm) 20 (2 ") ~ 400 (16") Nominal pressure PN (Mpa) 1.0 ~ 1.6 temperature (℃) 0 ~ 95 For medium water full pressure High-speed exhaust valve QSP parts Material: number represents 1,234,567 Part Name Body guide barrel buoy large exhaust components protect small exhaust assembly cylinder assembly destroy the material properties of cast stainless steel valve assembly assembly assembly copper High total pressure exhaust valve QSP use particulars: ① The vent valve must be installed at the highest point in the pipe or pipes at low (mounting location: a / pump outlet check valve on the horizontal pipe before, when the pump starts exhaust, When parking the breath; the horizontal pipe b / tubing downhill at; c / When the pump is stopped, it may create a vacuum or negative pressure at; d / long-distance pipelines, every horizontal pipe at 1-1.5 kilometers ; highest e / horizontal pipe, risers top); ② recommended to install shut-off valve at the bottom of the exhaust valve, to prepare for repair or replacement; ③ High total pressure exhaust valve QSP installation manual download.
