Abstract
The utility model relates to a L type is sealed firmly structure for V type ball valve. Including the V type ball valve that valve body, spheroid, locking seat, valve rod, ripper ring, disk seat constitute, still include the hard seal structure of the L type that constitutes by ripper ring, disk seat, the ripper ring is cyclic annular lamellar body, the disk seat is the ring bodies, is equipped with the round arch on the outside on face of ring bodies, in the valve body was arranged in to the spheroid, valve rod one end was arranged in the valve body together fixedly with the spheroid, in the valve body is arranged in proper order in to ripper ring, disk seat, the round of disk seat protruding with the ripper ring extrusion together, the locking seat is fixed mutually with the valve port of valve body one side, the ripper ring inner ring constitutes sealed during with the contact of spheroidal sphere, the material of disk seat is inconel X -750 nickelbase superalloy. The effect is: because the disk seat adopts the nickelbase superalloy material, have high rigidity, high elasticity, the heat resistance is good, the wearability is good characteristics. Adopt the hard seal structure of L type, make V type ball valve spillage can reach the IV level.
Description
Technical field
The utility model relates to a kind of L-type hard sealing structure, is mainly used in the hard sealing of V-type ball valve.
Background technique
At present, the seal form of the existing V-type ball valve of China has soft seal and firmly seals two kinds.Soft sealing structure valve seat is teflon material, and maximum operation (service) temperature is 250 DEG C, is requiring that the operating mode occasion of high temperature cannot realize sealing.Hard sealing structure maximum operation (service) temperature is 400 ~ 500 DEG C, and its valve seat and spheroid adopt the structure without built-up welding, part built-up welding and all built-up welding, and requiring the operating mode occasion of hard sealing structure, the leakage rate of these three kinds of hard seal form can not reach IV level.
Summary of the invention
In view of the situation of prior art and the deficiency of existence, the utility model provides that another kind of structure is simple, assembling is simple, the L-type hard sealing structure of V-type ball valve more efficiently when keeping in repair and change trim.
The utility model for achieving the above object, the technological scheme adopted is: a kind of L-type hard sealing structure of V-type ball valve, comprise the V-type ball valve of valve body, spheroid, stop-motion seat, valve rod, bearing ring, valve seat formation, it is characterized in that: also comprise the L-type hard sealing structure be made up of bearing ring, valve seat, described bearing ring is ring-type lamellar body; Described valve seat is ring bodies, the outside on ring bodies face is provided with a circle protruding; Described spheroid is placed in valve body, described valve rod one end is placed in valve body and is fixed together with spheroid, described bearing ring, valve seat are placed in valve body successively, one circle of valve seat is protruding to press together with bearing ring, the valve port of described stop-motion seat and valve body side fixes, and forms sealing surface during the sphere-contact of bearing ring inner ring and spheroid; The material of described valve seat is InconelX-750 nickel base superalloy.
The beneficial effects of the utility model are: L-type hard sealing structure is simple, assembling is simple, the simple and fast more when keeping in repair and change trim.Because valve seat adopts InconelX-750 nickel base superalloy material, there is high hardness, high elasticity, good heat resistance, feature that wear resistance is good.Adopt L-type hard sealing structure, make V-type ball valve leakage rate can reach IV level.
Accompanying drawing explanation
Fig. 1 is for adopting V-type ball-valve structure schematic diagram of the present utility model;
Fig. 2 is the enlarged view of Figure 1A.
Embodiment
As described in Fig. 1,2, a kind of L-type hard sealing structure of V-type ball valve, comprises valve body 1, V-type ball valve that spheroid 2, stop-motion seat 3, valve rod 4, valve seat 5, bearing ring 6 fit together formation, also comprises the L-type hard sealing structure be made up of valve seat 5, bearing ring 6.
Valve seat 5 is ring-type lamellar body.
Bearing ring 6 is ring bodies, the outside on ring bodies face is provided with the protruding 6-1 of a circle.
Spheroid 2 is placed in valve body 1, valve rod 4 one end is placed in valve body 1 and is fixed together with spheroid 2, valve seat 5, bearing ring 6 are placed in valve body 1 successively, the one protruding 6-1 of circle of bearing ring 6 and valve seat 5 press together, stop-motion seat 3 and the valve port of valve body 1 side are spirally connected fixing, compress valve seat 5 and bearing ring 6 by the valve body 1 that is threaded on stop-motion seat 3.
Under the effect of bleed pressure, actuator's output torque band ovable valve stem 4 rotates, and valve rod 4 drives spheroid 2 to do 90 ° of rotations, makes the inner ring of valve seat 5 and spheroid 2 sphere fit tightly formation sealing surface, realizes the sealing of V-type ball valve.
The material of valve seat 5 is InconelX-750 nickel base superalloy.
