Abstract
The utility model relates to the technical field of ball valve structure, in particular to a five-piece-type forged steel ball valve. A middle valve body and a side valve body are fixedly connected through a connector, and a positioning detent is arranged on the inner side of the connector. An independent valve seat template is arranged between a ball and the side valve body and connected with the ball in sealing mode, and an outer ring of the valve seat template is an outer valve seat. A sealing element is arranged on the end face of the outer valve seat, and the end face of the outer valve seat is connected with the inner face of the connector. A face of the outer valve seat, connected with the connector, is a thrust face shaped like a step. An inner ring of the valve seat template is an inner valve seat. A sealing element is arranged on the end face of the inner valve seat. A gap is arranged between the inner valve seat and the outer valve seat, and a plurality of springs connecting the inner valve seat and the outer valve seat are arranged on the gap.

Description
[technical field]
The utility model relates to the ball-valve structure technical field, specifically a kind of five chip forging steel ball valves.
[background technique]
The main single piece type of current ball-valve structure, two-piece type, three pieces type, upper dress formulas etc. are several.Single piece type wherein, two-piece type, three-flat ball valve no matter adopt shell cast or forging molding, all can't realize changing online internals because spheroid adopts side-mountedly.Particularly in the open air under the condition big-diameter ball valve in a single day break down, in the situation that heavy construction equipment can't arrive, safeguard very difficulty.As the term suggests the upper-mounting type ball valve spheroid can realize dress and on tear open, realized the on-line maintenance of ball valve, reduced labourer's workload.But upper-mounting type ball valve realizes the forging molding that except small-bore Large diameter all adopts casting basically because shell construction is complicated, because casting may produce the phenomenons such as the pore burning into sand is loose, housing has the possibility that leaks outside, and for poisonous and harmful medium operating mode, has increased potential safety hazard.
A kind of ball valve is disclosed such as domestic patent CN101614285B, the perpendicular distance of passing through expansion left and right sides auxiliary valve body of this ball valve reduces the operation moment of torsion, and possess simultaneously the characteristic of floating ball valve and fixing ball valve, but can't solving leakage in the on-line maintenance and part, this structure becomes scattered about problem in the pipeline.
[summary of the invention]
In order to solve the aforementioned problems in the prior and defective, the utility model provides a kind of both can realize on-line maintenance, the five chip forging steel ball valves that can avoid again housing to leak.
For achieving the above object, design a kind of five chip forging steel ball valves, comprise middle valve body, spheroid, valve rod, driver, lower shaft, the side valve body, flange plate and stuffing box, described middle valve body is fixedly connected with by connecting body with the side valve body, survey in the connecting body and be provided with positioning spigot, between described spheroid and side valve body, also be provided with independently valve seat module, the valve seat module is connected with ball seal, described valve seat module is toroidal, the outer ring of valve seat module is an outer seat, the end face of outer seat is provided with Sealing, the end face of outer seat is connected with the connecting body internal surface, and the surface that described outer seat is connected with connecting body is a step-like thrust face, and the inner ring of valve seat module is an interior valve seat, interior valve seat end face is provided with Sealing, inside and outside valve base chamber has a space, in the gap is provided with some springs connections, outer seat, described interior valve seat is connected with ball seal, interior valve seat and be provided with Sealing with the joint of spheroid, outer seat one side is provided with the limiting board that valve seat moves in the restriction.
Described Sealing is O type circle.
Described side valve body, middle valve body all are connected with connecting body by bolt.
Described outer seat and interior valve seat are provided with greasing annular groove and greasing hole.
The utility model is compared with prior art and is had the following advantages:
1. bolt is connected and is convenient to dismantle at any time between connecting body and middle valve body and the side valve body.
2. work as valve seat and abnormal conditions occur, when needing to change its assembly, can directly the valve seat module be taken out, prevent that component from becoming scattered about among the pipeline.
3. connecting body pushes away the inside with after positioning spigot contacts, and drive valve seat module moves to the spheroid direction, when sealing surface with after spheroid contacts, connecting body continues reach, with compression valve seat module inner spring, rely on the distortion of spring to produce the initial sealing pretightening force, thereby realize low pressure seal.
4. outer seat is with after the limiting board screw is connected, and valve seat construction length is fixed up, and has prevented the variation of valve seat module overall length in the unloading process.Be provided with interior valve seat between outer seat and the limiting board, when the variation of spring-compressed state, valve seat can slide front and back between outer seat and limiting board.Compress Spring behind the interior valve seat can be interior valve seat provides the O type circle on the valve seat circumference in the necessary pretightening force to guarantee sealing between the interior outer seat, and the O type circle on the outer seat circumference has guaranteed the effective sealing of valve seat module and connecting body.Greasing annular groove on the interior outer seat and greasing hole can provide effective greasing passage.
