Description
Technical field
The present invention relates to a kind of valve, a kind of specifically high pressure pipe joint plug valve that is applied on the petroleum industry special high-pressure manifold pipeline.
Background technology
As everyone knows, plug valve is a blowout prevention instrument in a kind of important drilling tool, when petroleum operations, for drilling well, well cementation, the needs of well workover, prevent blowout, well kick, often it is used on the high pressure pipe joint pipeline of special use, its structure of high pressure plug valve in the past is the structure of ball-type, there are many shortcoming and defect parts in above-mentioned structure, be in particular in: owing to what adopt is the structure of ball-type, the phenomenon of not opening after when the manifold line pressure is big, often occurring closing, and the workman just can't carry out next step operation like this, thereby can form safe hidden danger, cause the generation of accident.
Summary of the invention
The objective of the invention is to provide the high pressure pipe joint plug valve that a kind of simple and reasonable, opening and closing easily under the high pressure conditions of manifold pipeline, security performance are good, can not cause accident to take place.
The object of the present invention is achieved like this, this high pressure pipe joint plug valve comprises valve body, valve seat, flap, cylinder voussoir, loam cake, swivel nut, revolution switch, nut, lower cover, valve rod, guide peg, track pin, described loam cake is arranged on an end of valve body, swivel nut is installed in and covers, revolution switch is arranged on the outside of swivel nut and fixes by nut; The other end at valve body is provided with the lower cover that has track pin on it; Described valve seat is arranged on the valve body inside cavity, is provided with flap and cylinder voussoir in the valve seat; The valve rod that is connected with cylinder voussoir one end is arranged in loam cake and the swivel nut, and the guide peg that is connected with the cylinder voussoir other end is arranged in the lower cover.
Described cylinder voussoir is an oblique cone cylinder, is processed with two dovetail guides of symmetry on it, has the dovetail groove that is complementary with dovetail guide on the flap, and cylinder voussoir and flap can be by the slips that cooperatively interacts of dovetail groove on it and dovetail guide.
Described flap is symmetricly set on the both sides of cylinder voussoir, and they constitute combination valve core, and the face of cylinder of flap is sealing surface.
The present invention is owing to adopt said structure to have the following advantages:
(1), when high pressure pipe joint plug valve of the present invention opens and closes the combination faucet body sealing surface with the complete disengaged condition of sealing surface of seat under carry out, open and close therefore that moment is little, sealing surface does not have wearing and tearing, flexible operation.Simultaneously because when opening, when ball clack is lifted off a seat pipeline internal medium along the ball clack surface evenly by and at the uniform velocity step-down, so need not set up bypass during high pressure and just can open easily; And reduced medium at a high speed by the time to the local erosion of valve base surface, long service life.
(2) high pressure pipe joint plug valve of the present invention is realized sealing by mechanical force, and sealing performance is more reliable.
(3) high pressure pipe joint plug valve dual fail-safe self-locking of the present invention.Be the self-locking of screw thread and the self-locking at wedge cone wedge angle, safe and reliable.
Description of drawings
Fig. 1 is a high pressure pipe joint plug valve A-A face structure sectional view.
Fig. 2 is a B-B face structure sectional view of the present invention.
The specific embodiment
Shown in accompanying drawing 1,2: this high pressure pipe joint plug valve comprises valve body 1, valve seat 2, flap 3, cylinder voussoir 4, loam cake 5, swivel nut 6, revolution switch 7, nut 8, lower cover 9, valve rod 10, guide peg 11, track pin 12, described loam cake 5 is arranged on an end of valve body 1, swivel nut 6 is installed on the loam cake 5, it is fixing by nut 8 that revolution switch 7 is arranged on the outside of swivel nut 6; The other end at valve body 1 is provided with the lower cover 9 that has track pin 12 on it; Described valve seat 2 is arranged on valve body 1 inside cavity, is provided with flap 3 and cylinder voussoir 4 in the valve seat 2; The valve rod 10 that is connected with cylinder voussoir 4 one ends is arranged in loam cake 5 and the swivel nut 6, and the guide peg 11 that is connected with cylinder voussoir 4 other ends is arranged in the lower cover 9.
Described cylinder voussoir 4 is oblique cone cylinders, be processed with two dovetail guides 13 of symmetry on it, have the dovetail groove 14 that is complementary with dovetail guide 13 on the flap 3, cylinder voussoir 4 and flap 3 can be by the slips that cooperatively interacts of dovetail groove on it 14 and dovetail guide 13.
Described flap 3 is symmetricly set on the both sides of cylinder voussoir 4, and they constitute combination valve core, and the face of cylinder of flap 3 is sealing surface 15.
Described cylinder voussoir 4 radially has through hole 16.
The operating principle of high pressure pipe joint plug valve of the present invention is to adopt the principle of cam to make combination valve core break away from valve seat 2 sealing surfaces in rotary course, flap 3 is pushed to valve seat 2 after being rotated in place again and is realized sealing.
When combination valve core is in fully open position, rotate counterclockwise swivel nut 6 with revolution switch 7, when driving combination valve core in valve rod 10, guide peg 11 and the valve pocket and pressing track half-twist on the guide peg 11, valve rod 10, guide peg 11 and combination valve core are subjected to track pin 12 stop bits, rotation can not be continued, the motion that cylinder voussoir 4 makes progress as straight line can only be driven.Under the effect on inclined-plane, cylinder voussoir 4 both sides, two flaps 3 that will match with the inclined-plane strut presses to valve seat 2 realization sealings, combination valve core contract fully.
When combination valve core is in the contract fully position, clockwise rotate swivel nut 6 with revolution switch 7, driving valve rod 10, guide peg 11 and cylinder voussoir 4 moves downward as straight line, under the effect of inclined-plane dovetail groove 14, two flaps 3 that will match with the inclined-plane draw in lifts off a seat 2, be rotated further swivel nut 6, valve rod 10, guide peg 11 and combination valve core are by the position that reaches capacity of the rail groove half-twist on the guide peg 11, combination valve core standard-sized sheet.
