Abstract
The utility model discloses a high-pressure safety valve, which comprises a valve body, wherein the middle part of the valve body is provided with a through fluid channel; the upper end surface and the lower end surface of the valve body are respectively provided with fixing lugs; the side wall of the valve body is provided with a rotating shaft mounting seat; a rotating shaft is rotatably arranged in the rotating shaft mounting seat; and the rotating shaft is connected with a driving valve rod part through a screw. According to the high-pressure safety valve, the driving valve rod part is arranged on the rotating shaft; a larger torque can be applied through the valve rod manually when the safety valve cannot be opened automatically in emergency cases, and the safety valve is rapidly started; and the safety performance of the high-pressure safety valve is further improved.
Description
Technical Field
The utility model relates to a valve, more exactly, be a high pressure safety valve.
Background
In the field of high-pressure equipment manufacturing, a safety valve is a safety auxiliary device which is installed forcibly, can be opened fully and automatically released when the pressure of inlet steam or gas exceeds a preset value, and is an important safety part for preventing overpressure of a boiler and a pressure container. However, the existing safety valves may still fail, and in some cases, manual intervention is required to quickly actuate the safety valves.
Disclosure of Invention
The utility model discloses solve the technical problem that prior art exists to a high pressure safety valve is provided.
The above technical problem of the present invention can be solved by the following technical solutions:
the utility model provides a high-pressure safety valve, contains the valve body, the middle part of valve body be equipped with a fluid passage who runs through, the up end of valve body on with down the terminal surface on all be equipped with fixed ear, the lateral wall of valve body on be equipped with a pivot mount pad, a pivot rotatably sets up the pivot mount pad in, the pivot be connected with one drive valve stem portion through a screw.
As the preferred embodiment of the present invention, the driving valve rod portion comprises a first mounting post, a second mounting post and a valve rod, the first mounting post is fixedly connected to the rotating shaft.
As the preferred embodiment of the utility model, first erection column, second erection column and valve rod integrated into one piece.
The utility model discloses a high pressure safety valve sets up one in the pivot and drives valve rod portion, when the crisis condition takes place and safety valve can not open automatically, the manual work can apply great moment through the valve rod, and the quick start relief valve has further improved high pressure safety valve's security performance.
