Description
Technical field
The utility model relates to a kind of controller, relates in particular to a kind of ball-type controller.
Background technology
In high pressure line and fracture well head, often will use ball valve controller, it mainly plays control action. existing ball-type controller as shown in Figure 1, mainly comprise valve body 2, spheroid 3, valve rod 5, left valve 14, right valve 15, wave spring 16 parts such as grade, wherein left valve seat 14 1 sides are provided with wave spring 16, can automatically regulate the sealing surface 17 and spheroid 3 Surface Contacts of left valve seat 14, because wave spring 16 has elastic reaction, sealing surface 17 is just not easy seepage like this, spheroid 3 adopts surfacing Ni60 alloy simultaneously, but in such structure, it is metal sealing that spheroid 3 is followed between left valve seat 14 and right valve seat 15, although good seal performance, but difficulty of processing is large, and pipeline includes a large amount of sands, when left valve 14 and right valve 15 are opened, easily wiper seals face 17 of spheroid 3 surfaces, cause the lifetime of left valve 14 and right valve 15, cannot meet actual user demand.
Utility model content
The utility model object is to provide a kind of hardness high in order to overcome the deficiencies in the prior art, and production technology is simple, good seal performance, and easily processing, the ball-type controller of long service life.
For achieving the above object, the technical solution adopted in the utility model is: a kind of ball-type controller, comprises gland nut, valve body, spheroid, valve seat and valve rod; Described gland nut is fixedly arranged in valve body upper end; Described spheroid is arranged in valve body; Between described valve body and spheroid, be provided with two valve seats; Described valve rod is arranged in gland nut, and the lower end of valve rod is connected with the spheroid in valve body through gland nut; Also comprise sealing lining ring; On described valve seat with spheroid near a side be provided with valve seat groove; In described valve seat groove, be installed with sealing lining ring; The material of described sealing lining ring is PEEK; The material of described valve seat is 42CrMo.
Preferably, described spherome surface is coated with EMP layer.
Preferably, between described valve seat and valve body, be provided with an O type circle.
Preferably, between described gland nut and valve body, be also provided with successively Upper gasket, three fillers and lower gasket.
Preferably, described valve body one end is also connected with union joint; Between described union joint and valve body, be provided with several the 2nd O type circles.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages: the ball-type controller of the utility model scheme, it is simple in structure, hardness is high, and sand is difficult to destroy its surface, and production technology is relatively simple, good seal performance, low production cost and easily processing, long service life, has met actual user demand preferably.

Wherein: 1, gland nut; 2, valve body; 3, spheroid; 4, valve seat; 5, valve rod; 6, sealing lining ring; 7, valve seat groove; 8, an O type circle; 9, Upper gasket; 10, filler; 11, lower gasket; 12, union joint; 13, the 2nd O type circle; 14, left valve seat; 15, right valve seat; 16, wave spring; 17, sealing surface.
Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
Described in the utility model a kind of ball-type controller as shown in Figure 2-4, comprises gland nut 1, valve body 2, spheroid 3, valve seat 4 and valve rod 5; Described gland nut 1 is fixedly arranged in valve body 2 upper ends; Described spheroid 3 is arranged in valve body 2; Between described valve body 2 and spheroid 3, be provided with two valve seats 4; Described valve rod 5 is arranged in gland nut 1, and the lower end of valve rod 5 is connected with the spheroid 3 in valve body 2 through gland nut 1; Also comprise sealing lining ring 6; On described valve seat 4 with spheroid 3 near a side be provided with valve seat groove 7; In described valve seat groove 7, be installed with sealing lining ring 6; The material of described sealing lining ring 6 is PEEK; The material of described valve seat 4 is 42CrMo; Described spheroid 3 surfaces are coated with EMP layer; Between described valve seat 4 and valve body 2, be provided with an O type circle 8; Between described gland nut 1 and valve body 2, be also provided with successively Upper gasket 9, three fillers 10 and lower gaskets 11; Described valve body 2 one end are also connected with union joint 12; Between described union joint 12 and valve body 2, be provided with several the 2nd O type circles 13.
Described in the utility model a kind of ball-type controller as shown in Figure 2-4, it is mainly with being applied in high pressure line and fracture well head, the material of valve seat is 42CRMO, and by modified and surfaces nitrided processing, thereby hardness and the intensity of whole valve seat are improved, in valve seat, also have valve seat groove, when actual use, sealing lining ring is pressed onto in valve seat groove, finally valve seat and sealing lining ring are together processed into the sealing surface matching with the sphere of spheroid, thereby increase sealing, and the material of sealing lining ring is PEEK, can directly adopt threaded adjusting, although PEEK material hardness is high, but it does not belong to metal material, itself there is certain elasticity, sand is difficult to destroy its surface like this, meet actual user demand.
Simultaneously spherome surface is processed through modulation 270-320HB, and after fine finishining, finally by spherome surfaceization plating EMP, and thick 0.06-0.075, HV750-850, makes the higher and anticorrosion antiwear of hardness.
Ball-type controller of the present utility model, it is simple in structure, and hardness is high, and sand is difficult to destroy its surface, and production technology is relatively simple, good seal performance, low production cost and easily processing, long service life, has met actual user demand preferably.
Below be only concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation. All employing equivalents or equivalence are replaced and the technical scheme of formation, within all dropping on the utility model rights protection scope.
