Description
Technical field
The present invention relates to the valve controlled 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
Pipeline has installed relief valve additional, also results in the defect that installation volume is excessive, inconvenient to use, reliability is low.
Chinese patent 201220688956.1 discloses a kind of ball valve with pressure release, including valve body, valve chamber, import and goes out
Mouthful, it is equipped with rotatable spool in valve chamber, is equipped with the circulation passage that can be connected to inlet and outlet in spool, valve body is externally provided with rotation

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.
Summary of the invention
The technical problem to be solved by the invention is to provide one kind to be provided with pressure release energy when ball valve is closed and is opened
Power, and compact-sized, small in size, the high right angle ball valve with decompression function of use reliability.
Right angle ball valve with decompression function of the invention includes the valve body with valve chamber, and the different directions of valve chamber are provided with fluid
Entrance and fluid outlet are provided with the spool rotated by handle drives in valve chamber, and being provided on spool can be in specific rotation angle
The spool runner of fluid inlet and fluid outlet is linked up when spending, the rotation of spool being capable of opening and closing of fault fluid inlet；Valve body is also
It is connected with relief valve；The pressure release runner for linking up fluid inlet and pressure release valve inlet is provided in the matrix of valve body.
A preferred embodiment of the invention is: being closed on the outside of fluid inlet by upper end cover, is equipped with to enter with fluid in upper end cover
The inflow hole that mouth communicates；Pressure release notch is provided on inflow hole side wall, the pressure release runner passes through pressure release notch and fluid inlet phase
It is logical；Upper end cover lower end protrude into fluid inlet and with spool by upper seal it is in sealing contact.
Another preferred embodiment of the invention is: being closed on the outside of fluid inlet by upper end cover, fluid inlet inner end is fixed
Sealing shroud is installed, sealing shroud inside is in sealing contact by upper seal with spool；Gap between upper end cover and sealing shroud with
The pressure release runner communicates.
It is further preferred that the pressure release runner is the several segments arc interlayer positioned at body cavity periphery.
It is further preferred that the valve body lower portion connection has the lower cover of pressure-releasing chamber, relief valve is installed in pressure-releasing chamber；Institute
Pressure release runner is stated to be connected to by pressure-releasing chamber with pressure release valve inlet.
Further, valve body lower portion is provided with the pressure relief opening communicated with pressure-releasing chamber, pressure relief opening and spool runner when spool is opened
It communicates, pressure relief opening is closed by spool when spool is closed.
Further, spool and pressure relief opening inside are in sealing contact by lower seal.
Further, lower cover and valve body are an entirety.
Further, the valve body of relief valve and lower cover are an entirety.
The present invention installs right-angle valve and relief valve on a valve body concentratedly, compact-sized, small in size；And it seals
Link is few, high reliablity；Simultaneously because fluid inlet portion is communicated with pressure-releasing chamber always by interior pressure release runner, ensure that straight
