The diaphragm is more than high-pressure gas medium dynamic for the pressure value of the actual high-voltage gas medium in body cavity
When equilibrium state pressure threshold, high-pressure gas medium pushes the diaphragm uplink movement, and overcomes first spring pressure,
And then drive and the spool connected on the retainer is driven to move up, block the discharge orifice pipeline at the top of the valve port immediately, until resistance
It dies stream, the high-voltage regulator is stopped.
2. high-voltage regulator as described in claim 1, which is characterized in that
The body cavity bottom of the silk plug is provided with second spring, and is additionally provided with valve core case in the second spring；It is described
Valve core case is connect with the spool.
3. high-voltage regulator as described in claim 1, which is characterized in that
Junction between the valve body and the silk plug is additionally provided with gasket；And between the diaphragm and the retainer
Junction is additionally provided with gasket.
4. high-voltage regulator as described in claim 1, which is characterized in that
The bottom of the hexagon socket head cap screw is additionally provided with rubber sheet gasket.
5. high-voltage regulator as described in claim 1, which is characterized in that
Screwed connection cooperation is realized between the silk plug and the valve body.
6. high-voltage regulator as described in claim 1, which is characterized in that
The valve body is specially chalocopyrite structure valve body or stainless steel structure valve body.
7. high-voltage regulator as described in claim 1, which is characterized in that
The diaphragm is specially stainless steel metal diaphragm.
8. high-voltage regulator as claimed in claim 3, which is characterized in that
The gasket is specially tetrafluoroethene gasket seal.
9. high-voltage regulator as described in claim 1, which is characterized in that
The housing parts of the spool are specially chalocopyrite structure part, are embedded in house portion structure and are molded for nylon 1010.
10. high-voltage regulator as described in claim 1, which is characterized in that
