Description
Technical field
The present invention relates to valve fields, and in particular to suitable for the high-freedom degree open form plunger valve of oil-gas pipeline.
Background technology
Plunger valve is made of parts such as valve body, valve deck, valve rod, plunger, aperture frame, sealing ring, handwheels.When handwheel rotate,
By valve rod plunger is driven to pump to complete the open and close function of valve among aperture frame.The plunger in valve
With sealing interannular using being interference fitted, by adjusting flange bolt in gland, make lateral force and valve caused by sealing ring compression
Hole face and the sealing of plunger outer circle, so as to ensure that the leakproofness of valve, have prevented internal and outernal leakage while valve opening torque in body
It is small, it can realize that valve opens and closes rapidly.Plunger valve of the prior art is diconnected, fluid can wherein into
The two-way flowing of row, but existing plunger valve flows to that single, degree of freedom is low, only has switching function, after opening completely also only
There are one flow directions.
The content of the invention
It is an object of the invention to provide the high-freedom degree open form plunger valve suitable for oil-gas pipeline, to solve the prior art
Middle plunger valve flows to the problem of single, degree of freedom is low after opening completely, realize the degree of freedom of increase plunger valve, so that opening completely
There is the purpose of more flow directions afterwards.
The present invention is achieved through the following technical solutions：
Suitable for the high-freedom degree open form plunger valve of oil-gas pipeline, including four-way body, it is arranged at four-way body central
Plunger, for the plunger for insulating at the center of four-way body, four open ends of the four-way body are respectively and fixedly provided with flange
Disk sets runner on the plunger, and the axis of the runner is perpendicular to plunger axis；Further include the valve for being fixed on plunger at one end
Handwheel is fixed in bar, the one end of the valve rod away from plunger, and the handwheel is located at four-way outer body；The plunger is away from valve rod
One end is arranged to semi-convex spherical surface, sets the groove of semi-convex spherical surface described in face on the four-way body, the groove be in it is semi-convex
Isometrical hemispherical, the groove inner wall laying rubber pad of spherical surface；When semi-convex spherical surface and rubber pad fit, the runner
The axis co-planar of axis and four-way body.
The problem of single, degree of freedom is low is flowed to after being opened completely for plunger valve in the prior art, the present invention proposes to be applicable in
In the high-freedom degree open form plunger valve of oil-gas pipeline, including four-way body, plunger, the four-way are set at the center of four-way body
The center of body is the intersection of two orthogonal runners in four-way, and plunger is used to insulate the runner that four-way respectively crosses,
So that the runner of four direction is kept apart by plunger.Four open ends of four-way body are respectively and fixedly provided with ring flange, convenient for quick
Exterior tubing and the present invention are attached, improve the present invention installation connection when efficiency.Runner, user are set on plunger
By rotation valve rod, plunger rotation is driven so that runner is connected with the opposite sides of four-way body, you can realizes the stream of fluid
It is dynamic.Handwheel is fixed in the one end of valve rod away from plunger, is operated easily and fast from four-way body exterior convenient for user, improves
The operability of the present invention.The one end of plunger away from valve rod is arranged to semi-convex spherical surface, and semi-convex spherical surface is outwardly hemisphere
Shape curved surface, sets the groove of semi-convex spherical surface described in face on four-way body, groove be in isometrical hemispherical of semi-convex spherical surface, therefore
The semi-convex spherical surface of plunger end can enter in groove just to be bonded with groove inner wall, along with groove inner wall is equipped with rubber
Pad, therefore rubber pad can be squeezed during semi-convex spherical surface enters groove, realize semi-convex spherical surface in groove by rubber pad
Sealing, prevents fluid channelling in groove, it is ensured that the isolation on each flow direction of four-way.Due between hemisphere convex surface and groove simultaneously
Unlocked connection hence the plunger in the present invention has more degree of freedom, can be moved along plunger axis direction
It is dynamic.During normal use of the present invention, semi-convex spherical surface is located in groove, at this time the axis co-planar of the axis of runner and four-way body,
Plane residing for the axis of middle four-way body is the plane that the axis of each flow direction of four-way body is collectively constituted, flows at this time
Road also is located in the plane so that the flow surface of runner face four-way body, user only need to rotate handwheel from outside, drive column
Plug rotates, and can realize the purpose that any two relative direction of four-way is connected or turned off, while can also pass through
The angle of rotation valve rod adjusts uninterrupted.When needing four flow directions using four-way, it is only necessary to towards handwheel place side
To outwards stirring valve rod so that valve rod drives plunger movement, so as to which the semi-convex spherical surface of plunger end be extracted from groove, at this time
Fluid is flowed from groove, and the four direction of four-way body is connected, so that having after plunger valve fully opens
There are more flow directions, solve the problems, such as that it is still single to fully open rear flow direction for plunger valve in the prior art.
Preferably, the rubber pad is Nian Jie with groove inner wall.Ensure to connect between rubber pad and groove by bonding connection
It is firm, it prevents from extracting and takes rubber pad out of disengagings during hemisphere convex surface, improve stability in use of the invention.
Preferably, the thickness of the rubber pad is 0.6~0.9cm.The blocked up semi-convex spherical surface of influence of rubber pad is filled in groove,
It is excessively thin and good sealing performance cannot be played, thus this programme by the thickness limit of rubber pad 0.6~0.9cm scope
It is interior, it is ensured that the excellent performance of rubber pad.
Preferably, the plunger is pierced by four-way outer body, and four-way body interior sets the sealing ring for encircling plunger.I.e.
It is that the contact site of plunger and four-way body is sealed by sealing ring, further improves the sealability of the present invention, prevents
Fluid stopping is overflow in vitro, improves the performance of the present invention.
Preferably, the sealing ring is polytetrafluoroethylsealed sealed circle.
Preferably, the outer surface of the ring flange is embedded steel ring, and the steel ring and ring flange are concentric.Improve ring flange
Sealability without being additionally sealed using air locking, greatly improves the ease of use of the present invention, it is ensured that with outside
Sealing performance when pipeline connects.
Compared with prior art, the present invention it has the following advantages and advantages：
The present invention is suitable for the high-freedom degree open form plunger valve of oil-gas pipeline, between hemisphere convex surface and groove and unlocked company
It connects, hence the plunger in the present invention has more degree of freedom, can be moved along plunger axis direction.By plunger
The semi-convex spherical surface of end is extracted from groove, and fluid is flowed from groove at this time, and the four direction of four-way body is connected
It is logical, so that having more flow directions after plunger valve fully opens, solve plunger valve in the prior art and open completely
Open the problem of rear flow direction is still single.
