Description
Technical field
The utility model relates to a kind of valve, especially a kind of floating ball valve stable-pressure device for gas medium.
Background technique
Floating ball valve is small in size, light-weight, and structure is simple, and sphere has the function of free floating, can preferably guarantee to seal；
Ball valve is to use the sphere with circular through hole as opening and closing element, makees 0 ~ 90 degree of rotation around valve rod center in valve rod driving lower sphere
Turn, completes opening and closing function；Have the characteristics that compact-sized switch is rapid, rotate 90 degree, valve can be closed, cutting pipeline is situated between
Matter；Sphere channel diameter is identical as pipeline diameter, and flow resistance is small, and negotiability is big；Valve rod is down-mounting type, has prevented what valve rod was pierced by
Accident occurs, and ensure that using safe.But floating ball valve is due to its design feature, unbearable biggish pressure, when gas in valve
When body pressure is larger, sphere is easy to happen offset, or even damage.
Summary of the invention
The technical problem to be solved by the utility model is to provide a kind of floating ball valve stable-pressure device for gas medium,
Of short duration shunting can be carried out to the air pressure of increase in a short time, win the more time for processing in next step.
It is a kind of for the floating of gas medium that in order to solve the above technical problems, the technical scheme adopted by the utility model is:
Dynamic ball valve stable-pressure device, including valve body, are equipped with sphere and valve seat in valve body, and the valve seat is set to the left and right ends of sphere, institute
The upper end for stating sphere is equipped with valve rod, and the valve rod and sphere and valve body are rotatablely connected, and the valve body includes air water end and outlet side,
Gas tank is connected on the side wall of valve body inlet end, the lower end of the gas tank is equipped with air inlet pipe, the air inlet pipe and valve body screw thread
Connection is equipped with exhaust apparatus in air inlet pipe.
