Description
Technical field
This utility model provides one regulation valve, especially a kind of Pneumatic high-pressure regulation valve.
Background technology
Pneumatic high-pressure regulation valve be mainly used in the high pressure of industry such as oil, chemical industry, chemical fertilizer, generating, High Pressure Difference operating mode from
In autocontrol system, process conditions are relatively severe, higher to the regulation reliability of valve, security requirement.Pneumatic high-voltage regulates
Valve is mainly used for the severe service such as high pressure, High Pressure Difference, owing to pressure medium is high, flow velocity is fast, will produce cavitation, if
Spool, valve seat material without special superpressed process, spool, valve seat can be produced serious erosion damage, make the valve cannot
It is continuing with, is greatly shortened the service life of regulation valve, makes user have to prepare substantial amounts of spare part and be replaced.
Utility model content
In order to overcome the deficiencies in the prior art, this utility model provides a kind of Pneumatic high-pressure regulation valve, and this pneumatic high-voltage is adjusted
Joint valve, is not only simple in structure, easy to use, and Pneumatic high-pressure regulation valve uses cage throttling form to share pressure reduction, reduces
Cavitation erosion, erosion, flow disturbing are destroyed, and substantially increase service life of regulation valve.
This utility model solves above-mentioned technical problem and be employed technical scheme comprise that；
A kind of Pneumatic high-pressure regulation valve, including regulation valve body, described regulation valve body include valve body, spool, valve gap and
Valve rod, described spool is placed in valve body, and one end of spool is provided with sleeve, and by sleeve segmentation water inlet and outlet, institute
Stating valve rod to be placed in valve gap, described valve gap is assembled with valve body by bolt, and one end of valve rod contacts with spool, and is provided with pad
Sheet, the valve gap of described regulation valve body is provided with pneumatic means, and described pneumatic means drives regulation valve body work.
Described valve gap is provided with installing hole, is provided with spring, filler pad and filler in described installing hole, and described spring housing is connected on
On valve rod, filler is placed in the lower end of spring, and filler pad is placed in the upper end of spring, and by nut seal installing hole.
Described pneumatic means includes that motor, containment vessel and connecting rod, described motor are placed in containment vessel, and motor is by connecting
Bar is connected with valve rod, and is fixed by fixing bolt.
Antirust coat is all scribbled on the containment vessel of described regulation valve body and pneumatic means.
The beneficial effects of the utility model: this Pneumatic high-pressure regulation valve, are not only simple in structure, easy to use, and pneumatic
Septum valve uses cage throttling form to share pressure reduction, decreases cavitation erosion, erosion, flow disturbing destruction, substantially increases regulation
The service life of valve.
