Embodiment 1

[0013] Embodiment 1 of the present invention: refer to figure 1 As shown, Embodiment 1 of the present invention: an overpressure automatic exhaust valve, which mainly includes an air inlet 1, a valve body 2, a valve seat 3, a valve seat support frame 3-1, a flap 4, a valve cover 5, The exhaust port 6 and the valve seat 3 are communicated with the valve body 2 through the hose 7 , and the two are fixed by the leveling screw 8 . The top of the valve seat 3 is equipped with a bubble level indicator 9 . The material of the disc 4 is preferably Teflon plastic.

[0014] After the above structure is adopted, when the pressure in the pipeline connected to the air inlet 1 exceeds the design pressure value, the flap 4 is automatically opened vertically and the gas is discharged; when the exhaust pressure is lower than the design pressure, the flap 4 automatically Descend vertically to close the gas to prevent the gas from being discharged. After the overpressure automatic exhaust val...

Abstract

The invention relates to an automatic overpressure exhaust valve which comprises an air inlet (1), a valve body (2), a valve base (3), a movable disk (4), a valve cover (5) and an exhaust port (6), wherein the air inlet is formed in the bottom of the valve body and is provided with a hose (7); the valve base (3) is communicated with the valve body (2) through the hose (7) and supports the valve body; the valve base and the valve body are fixed by leveling screws (8); the movable disk (4) is mounted above the valve base; and the movable disk is a gravity type valve sheet. At least three leveling screws are arranged between the valve base and the valve body; and a bubble level indicator is arranged at the top end of the valve base. After the structure is adopted, when the pressure in the pipeline communicated with the air inlet exceeds a designed pressure value, the movable disk is opened automatically in a vertical direction to discharge the gas; and when the discharge pressure is lower than the designed pressure, the movable disk drops automatically and vertically to prevent the gas from being discharged.

Description

technical field [0001] The invention relates to an overpressure automatic exhaust valve, which is used for overpressure automatic exhaust. Background technique [0002] The conventional overpressure automatic exhaust valve adopts the principle of dead weight, so the installation level of the overpressure automatic exhaust valve will affect the accuracy of the exhaust starting pressure. SUMMARY OF THE INVENTION [0003] (1) Purpose of the invention [0004] The purpose of the present invention is to propose an overpressure automatic exhaust valve in view of the problems to be solved in the above-mentioned prior art. Air actuation pressure accuracy. [0005] (2) Technical solutions [0006] The present invention is realized as follows: an overpressure automatic exhaust valve includes an air inlet, a valve body, a valve seat, a flap, a valve cover, and an air outlet. The air inlet opens a hole at the bottom of the valve body, and is provided with The hose and the valve se...
