Description
Technical field
The present invention relates to a kind of ball valve, and in particular to a kind of safety valve pressure testing equipment Multifunction ball valve.
Background technology
External force mechanisms must be increased in safety valve pressure test to pipeline additional external force, external force mechanisms install complicated, scene
Not easy to operate, the relief valve scene on-line checking time is long；In detection process, to lasting pumped (conveying) medium, then inside pipeline
Air pressure need longer time to can be only achieved stable safety valve test air pressure, once and external force mechanisms provide gas with
Pipeline internal gas uniformly can not mix before reaching relief valve, and the test result of relief valve is inaccurate.
Ball valve flexibly can control on pipeline the interflow of medium, shunting, and flow direction switching, it is only needed to being rotated by 90 °
Operation and the rotating torque of very little just can close tightly.Ball valve optimum is switched, stop valve is used.Try in safety valve pressure
In testing, also it is utilized at present connecting external force mechanisms on pipeline, not only results in pipeline anti-pressure ability decrease and cannot also ensure outer
The gas that force mechanisms are provided can be uniform with pipeline internal gas.
The content of the invention
The technical problem to be solved is the gas and pipe of external force mechanisms offer in safety valve pressure on-line checking
Road internal gas before relief valve is reached were unable to mix homogeneously and reach stable air pressure, it is therefore intended that provide a kind of relief valve
Pressure testing device Multifunction ball valve, solves how can flexibly control the interflow of medium, shunting, and cutting of flowing to using ball valve
The advantage changed causes the gas that external force mechanisms are provided uniformly to mix the degree of accuracy so as to improve testing result with pipeline internal gas
Problem.
The present invention is achieved through the following technical solutions：
A kind of safety valve pressure testing equipment Multifunction ball valve, including valve body, the valve inner is provided with passage, institute
Channel connection is stated to valve body two ends, the two ends of valve body are fixed with seal receptacle, the seal receptacle and channel connection, and the inside of valve body sets
It is equipped with the spheroid in interior apertured road, the spheroid is located in passage, spheroid is not connected with valve rod, valve rod one on the side wall in apertured road
End is connected with spheroid, and the valve rod other end passes through valve body, offers through hole, the through hole and channel connection on the side wall of valve body.
A kind of safety valve pressure testing equipment of present invention Multifunction ball valve is used in the pressure detecting test of relief valve, peace
External force mechanisms are needed to provide external pressure so that the pressure value in relief valve detecting system reaches safety to relief valve in full valve detection
The set-pressure of valve, if relief valve is opened under the external force of the safety valve set pressure value, then relief valve is qualified, no
Then, relief valve is unqualified.In the present invention, ball valve realizes the conjunction of flexibly control medium by the angle for changing the spheroid of channel interior
Stream, shunting, spheroid outer wall are tangent with vias inner walls, and ball interior offers duct, state and passage of the duct in ball valve standard-sized sheet
Connect completely, on spheroid, on only one of which direction, offer duct, spinning ball, spheroid is rotated by 90 ° will can be by by spheroid
Channel seal, spheroid rotate in one direction, can adjust the flow of valve inner medium in rotary course；Seal receptacle is used for close
The conveyance conduit of envelope interface channel two ends connection, passage is for the flow of media in conveyance conduit；The present invention principle be：In ball valve
On open up through hole, through hole is connected with external force mechanisms, when external force mechanisms are passed through gas-pressurized to the inside of ball valve pass through rotating sphere
In the gas and pipeline that the gas that control external force mechanisms are provided causes external force mechanisms to provide with pipeline internal gas and mixing velocity
Portion's gas mixing is uniform, reaches stable pressure, and valve rod is used for controlling spheroid rotation, and ball valve can flexibly control medium conjunction by which
The advantage of stream is uniform by the gas mixing being passed through inside pipeline, and mixed gas can produce stable pressure when arranged at safety valve is reached
And the pressure is identical with safety valve set pressure, therefore improve the levels of precision of relief valve detection.
The through hole is for manhole and through-hole inner surface is smooth.Through-hole inner surface is smooth just not to have larger choked flow
Effect.
The centre of sphere of the spheroid is on the extended line of through-bore axis.The speed that is passed through of external force mechanisms gas is also by ball valve
Inner ball rotates control, therefore, through hole is in just to relation with spheroid.
The internal diameter size of the through hole is equal to the straight of spheroid less than the internal diameter size and the through hole internal diameter size of passage
Footpath size.Through hole is located on the wall of valve body side, and the aperture of through hole is little to be easy to improve the speed that external force structure is passed through gas, and leads to
The internal diameter in the hole duct internal diameter size for meaning ball interior identical with sphere diameter just has one less than the internal diameter of through hole to through hole
Fixed choked flow effect.
Connect handle on the valve rod, on the handle, be coated with thermal insulation layer.Equipment in operation, environment under high pressure one
As can simultaneously with the environment of high temperature, thermal insulation layer avoids high temperature burn operator.
Signal inductor, the signal inductor are installed on the inwall of the passage between the through hole and valve body outlet side
For temperature, pressure signal induction apparatuss.Signal inductor is used for determining mixed gas initial mixing pressure.
The present invention compared with prior art, has the following advantages and advantages：
1st, a kind of safety valve pressure testing equipment Multifunction ball valve of the invention opened hole, through hole on the wall of ball valve side
It is connected with external force mechanisms, in safety valve pressure test, rationally make use of ball valve flexibly to control the advantage of the interflow of medium, shunting
So that keeping the gas and pipeline internal gas that uniform mixing external force mechanisms are provided in the case of continuous transmission medium inside pipeline
So as to reach stable test pressure, improve the degree of accuracy of relief valve testing result, shorten detection time；
2nd, a kind of safety valve pressure testing equipment Multifunction ball valve of the invention, the bearing capacity of ball valve are strong and ball valve
Good airproof performance, on ball valve, perforate is simpler compared with the perforate on pipeline and perforate can avoid pipeline from opening on ball valve
The problem split；
3rd, a kind of safety valve pressure testing equipment Multifunction ball valve long service life of the invention, low production cost, external force
Mechanism is arranged on ball valve, and installation cost is low.
