Abstract
A kind of stomatal conductivity formula Decompression valves, comprise outer seat 13, interior valve seat 15, valve gap 4, filler opening 12, oil outlet 11, circular seal cover 1, piston rod 6, piston 14, telescopic bar core 9, spring 10 and pressure release runner 8 are formed, outer seat 13 upper end is provided with valve gap 4, valve gap 4 is fixed by bolt 5 and outer seat 13, telescopic bar core 9 is provided with bottom interior valve seat 15, telescopic bar core 9 overcoat has spring 10, the interior valve seat 15 of spring 10 surrounding is provided with pressure release runner 8, piston 14 is provided with directly over telescopic bar core 9, piston 14 and interior valve seat 15 closely cooperate and can slide up and down, piston 14 is connected with piston rod 6, piston rod 6 upper end to be placed in circular seal cover 1 through valve gap 4 and valve seat 13, circular seal cover 1 is fixed by bolt 3 and valve gap 4.The beneficial effects of the utility model are: adopt the adjustable pressure release valve device of steam-hole type, simplify the pressure controlled structure of Decompression valves, improve pressure controlled ability and stability, realize the automatic regulation function of pressure size.
Description
Technical field
The utility model relates to a kind of stomatal conductivity formula safety valve, especially for adjustable pressure relief valve.
Background technique
Existing pressure relief device is generally arranged on pipeline, automatically opens pressure release when the pressure in pipeline exceedes pressure relief device setting pressure, to ensure that pipeline internal medium pressure is no more than setting pressure, carrys out protective conduit.
Summary of the invention
In order to optimize existing Decompression valves, the utility model provides a kind of stomatal conductivity formula Decompression valves.
The utility model solves the technological scheme that its technical problem adopts: valve seat is divided into outer seat and interior valve seat, outer seat upper end is provided with valve gap, valve gap is fixed by bolt and outer seat, interior valve seat is cylinder type, interior seat bottom portion is provided with telescopic bar core, telescopic bar core overcoat has spring, the interior valve seat of spring surrounding is provided with pressure release runner, piston is provided with directly over telescopic bar core, piston is provided with some through holes, piston and interior valve seat closely cooperate and can slide up and down, piston is connected with piston rod, piston rod upper end enters in circular seal cover through valve seat and valve gap, described circular seal cover is fixed by bolt and valve gap.
A kind of optimized project of such scheme is: the pressure release Flow diameter of described spring surrounding inwall successively increases from top to bottom.
Liquid is by making piston move down to piston mineralization pressure during piston hole, when piston moves to below pressure release runner, liquid is flowed out by pressure release runner and pressure is reduced, and when pressure decreases, the spring below piston forms elastic force to piston makes piston move up.
The beneficial effects of the utility model are: adopt the adjustable pressure release valve device of steam-hole type, simplify the pressure controlled structure of Decompression valves, improve pressure controlled ability and stability, realize the automatic regulation function of pressure size.
