Description
Technical field
The valve that the utility model relates to control for fluid, specifically a kind of right angle ball valve with decompression function.
Background technique
Valve of the ball valve relative to other control pipeline medium circulations, has many advantages, such as that resistance of medium is small, easy to operate.Especially
It is right angle ball valve, in some size-constrained corner locations, has installation dimension compact, the neat and artistic advantage of shape.In
State's patent 201620147991.0 discloses a kind of right angle ball valve, valve body, water inlet pipe, valve rod, core including having outlet pipe
And handle, inner end is connect with core after valve rod is fed through valve body, and valve rod outer end is connect with handle, and water inlet pipe is connected to valve body phase
For the side of core, valve outer wall is additionally provided with locating piece, and there are two be symmetrical arranged and rotate with locating piece for setting on handle
The locating slot of abutting.By realizing that handle continuous rotation can realize opening and closing valve body in one direction, compared with prior art
The pipeline of valve body connection is influenced smaller；And locating piece can be very good to determine whether core opening and closing is thorough, and it is easy to operate.
However, in practical applications, when this ball valve is installed in the equipment or pipeline of closed system, cut-off equipment or
In pipeline when the flowing of medium, generally require to carry out pressure release to the closed system, to guarantee that pressure medium exists in equipment and pipeline
It sets under pressure, protects equipment and pipeline, prevent accident.Therefore it needs to install relief valve additional while mounting ball valve,
But there is the occasion of considered critical in duct length size, install relief valve additional and limited and be difficult to realize by space, even if external reluctantly

Pressure release passage, the outer wall of valve body are equipped with pressure release valve seat, pressure-releasing chamber, one end of pressure-releasing chamber and pressure release entrance are equipped in pressure release valve seat
It is connected, the other end is equipped with pressure relief vent, and it is equipped with partition in pressure-releasing chamber, valve opening is equipped in partition, is equipped with a valve rod in valve opening,
And valve rod can slide in valve opening, one end end of valve rod is equipped with piston, and the end of piston is enclosed on pressure release entrance, valve rod
On be set with the spring being supported between partition and piston.Ball valve and relief valve are combined into one by the structure, and structure is compacter,
It is small in size.However, the program is only in the open state in valve, when entrance and exit connection, pressure-releasing chamber could communication medium
Channel, decompression function is effective, when ball valve core is in close state, by reserving pressure release in pressure-releasing chamber side to the ball valve core
Access opening, decompression function also can only distich pass ball valve outlet section pressure medium it is effective, can not be to the entrance closed by ball valve
The pressure medium of preceding closed state plays the role of pressure release.And actual conditions many places are in ball valve core and close, to close side
Medium need the condition of decompression protection.Chinese patent 201510696470.0 discloses a kind of safe ball with decompression function
Similarly there is drawbacks described above in valve.
