Description
Technical field
The present invention relates to a kind of ultrahigh pressure ball valve, relate in particular to a kind of replaceable spool ultrahigh pressure ball valve.
Background technique
The highest 32Mpa (≈ 320Kg) that is no more than of high pressure hand-operated ball valve nominal pressure that produces through the present domestic manufacturer of investigation, latus rectum are below DN32, and nominal pressure all needs import at 32Mpa, ultrahigh pressure ball valve more than the DN32.The spool under high pressure and ultrahigh pressure and the wearing and tearing of Sealing also cause valve to need frequent change, and fault treatment is got up cumbersome.
Summary of the invention
The objective of the invention is to overcome the shortcoming of prior art, a kind of ultrahigh pressure ball valve that can satisfy a kind of replaceable spool of high pressure, the requirement of ultrahigh pressure pipeline is provided.
The ultrahigh pressure ball valve of replaceable spool of the present invention; It comprises valve body; In described valve body, comprise supporting frame; Left valve seat, ball valve core, right valve seat are installed in described supporting frame from left to right successively; The upper and lower surface of contact of described supporting frame and left valve seat, ball valve core, right valve seat is the plane, and the left end of described left valve seat is arranged on outside the supporting frame left side and is close to the supporting frame left side through boss face and cooperates, and at described valve body left end suction flange is installed; At described valve body right-hand member outlet(discharge) flange is installed; Be equipped with successively in the top perforate in the middle of described valve body in upper end cap and upper bearing (metal), the bottom perforate in the middle of described valve body lower end cap and lower bearing are installed successively, in the perforate of described upper and lower end cap, be inserted with upper shaft, lower end axle respectively, described upper shaft, lower end axle link to each other with the ball valve core through linkage structure respectively; In the perforate of described suction flange right-hand member and between the left valve seat left side, spacer ring is installed; On described supporting frame and the contacted left end outer wall of valve body inner bore wall, have the left side circular groove, in the circular groove of described left side, jump ring is installed, on described supporting frame right-hand member and the contacted outer wall of outlet(discharge) flange inner hole wall, have the right side circular groove; In the circular groove of described right side, seal ring is installed, between the described supporting frame endoporus step surface on right side and right valve seat right side, the butterfly spring is being installed.
Ultrahigh pressure ball valve of the present invention can satisfy the requirement of high pressure, ultrahigh pressure pipeline.This type of valve is widely used in the production link of various media such as petrochemical industry, ocean engineering, naval vessel and fuel, combustion gas and transfer line.This ball valve structurally the suction flange end spacer ring of an erosion, the main effect of this spacer ring are arranged is to prevent the impingment corrosion to valve body and valve device of high pressure, high speed medium, the working life of improving valve.As long as in use pull down an end flange (suction flange 1 or outlet(discharge) flange 4) in case leakage takes place, extract former valve body 2 out, change new valve body and can recover to use, easy to maintenance, fault treatment is convenient.The user needs only a subsequent use 1-2 valve body can satisfy job requirement, and needn't change whole ball valve, cuts down expenses.

Embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is done to describe in detail.
The ultrahigh pressure ball valve of a kind of replaceable spool of the present invention as shown in the figure; It comprises valve body 2; In described valve body, comprise supporting frame 3; Left valve seat 10, ball valve core 5, right valve seat 6 are installed in described supporting frame from left to right successively; The upper and lower surface of contact of described supporting frame and left valve seat 10, ball valve core 5, right valve seat 6 is the plane, and the left end of described left valve seat 10 is arranged on outside the supporting frame left side and is close to the supporting frame left side through boss face and cooperates, and at described valve body left end suction flange 1 is installed; At described valve body right-hand member outlet(discharge) flange 4 is installed; Be equipped with successively in the top perforate in the middle of described valve body in upper end cap 13 and upper bearing (metal) 14-1, the bottom perforate in the middle of described valve body lower end cap 13 and lower bearing 14-2 are installed successively, in the perforate of described upper and lower end cap, be inserted with upper shaft 16-1, lower end axle 16-2 respectively, described upper shaft, lower end axle link to each other with ball valve core 5 through linkage structure respectively.Described linkage structure can be key 15.Handle 12 preferably is installed on upper shaft; In described suction flange 1 right-hand member perforate and between left valve seat 10 left sides spacer ring 9 is installed; On described supporting frame 3 and the contacted left end outer wall of valve body inner bore wall, have the left side circular groove; In the circular groove of described left side, jump ring 11 is installed; On described supporting frame 3 right-hand members and the contacted outer wall of outlet(discharge) flange 4 inner hole walls, have the right side circular groove, in the circular groove of described right side, seal ring 8 is installed, between the described supporting frame 3 endoporus step surfaces on right side and right valve seat 6 right sides, butterfly spring 7 is being installed.
Under low-pressure state, there is the butterfly spring 7 of certain pretightening force to push ball valve core 5 to left valve seat 10, they are kept in touch and certain contact force arranged.If have low-pressure fluid to flow through this moment, because ball valve core 5 closely contacts with left valve seat 10 and certain pretightening force is arranged, fluid can not missed.Along with hydrodynamic pressure raises gradually, pretightening force is not enough to when fluid-encapsulated, under butterfly spring 7 and jump ring 11 relative pressure effects; Ball valve core 5 and right valve seat 6; Form double seal between the valve seat 10 of a left side, this sealing force is directly proportional with hydrodynamic pressure, and hydrodynamic pressure is high more; Sealing force is big more, thereby realization ultrahigh pressure is not revealed.
Between described suction flange 1 right side and left valve seat 10 left sides, spacer ring 9 is installed, this spacer ring can prevent the impingment corrosion to valve body of high pressure, high speed medium, the working life of having improved valve.
