The upward compression spring of piston rod is simultaneously moved up along cylinder body, and block moves up so that upper valve body and first-level buffer case
It is connected, medium is directed into first-level buffer case by delivery line, so that dielectric leakage is avoided, when the pressure in baffle-box reaches
When setting value, the buzzer on first-level buffer case be will start, and open the control valve on communicating pipe, and medium enters level 2 buffering case
Interior, after the pressure in level 2 buffering case reaches setting value, on level 2 buffering case buzzer starting.
3, valve deck bottom is fixedly connected with Sealing shield ring, and block side wall is equipped with gasket, improves the intracorporal sealing of upper valve
Property, avoid the medium in pipeline from leaking outside.
4, stop bottom offers head tank, and head tank is set as hemispherical configuration, so that the medium in pipeline acts on
During block moves up, stress is more balanced.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
