When relief valve is closed, pressure release epicoele 51 connects the present invention with piston cavity 72；When relief valve is opened, under pressure release
Chamber 52 connects with piston cavity 72.
The operation principle of the present invention is as follows：
Medium flow direction as shown in Figure 1, upstream pressure P1 and downstream pressure P2 make at the region between the valve seat 4 of piston 7 and first
For boundary, upstream pressure P1 slowly enters piston cavity 72 by needle-valve 65 of intaking, and downstream pressure P2 then passes through connecting pipe 64
Into horizontal through hole 54 and pressure release cavity of resorption 52.Whether pressure releasing valve core 503 is opened, and its condition is pressed into the downstream of horizontal through hole 54
Whether power P2 overcomes the elastic force of elastomeric element 504.If downstream pressure P2 is raised, caused thrust is more than spring force, then pressure release
Valve element 503 is up, and pressure relief opening is closed, and now piston cavity 72 is only connected by needle-valve 65 of intaking with upstream, then piston cavity 72
Pressure rise, piston 7 perform closing motion；When piston 7 is closed, downstream pressure P2 starts to reduce, when P2 decreases below bullet
During spring force, pressure releasing valve core 503 is opened, and downstream pressure P2 enters pressure release epicoele 51, and now piston cavity 72 connects pressure release epicoele 52,
Due to bore of the pressure relief opening much larger than water inlet needle-valve, therefore the pressure of piston cavity 72 starts to reduce, and piston 7 performs breakdown action
（Because the actuating pressure of the ring surface 70 of piston 7 is P1, when the pressure of piston cavity 72 is P2, now to the right, i.e., piston stress is
Piston 7 performs valve opening action）, therefore, when the elastic force of elastomeric element 504 is constant, piston 7 is in a kind of dynamic flat
Weighing apparatus state, it is ensured that downstream pressure P2 reaches setting value, so as to reach the purpose of decompression.
In summary, presently preferred embodiments of the present invention is these are only, the scope of the present invention should not be limited with this.It is i.e. all
It is the simple equivalent changes and modifications made according to claims of the present invention and description, all should still belongs to patent of the present invention
In the range of covering.
