Abstract

A top mounted ball valve of an inner-propped compound seal forged steel is applicable to pipeline control, belongs to the technical field of valves, and is characterized in that a compound seal valve seat structure fixed through a clamp ring is adopted, and the displacement stroke of the valve seta is designed into an inner-propped type, therefore, no mounting and dismounting hole is required to be formed outside the valve body, the leakage points liable to leak are reduced, and the top mounted structure of the valve is achieved. The top mounted ball valve can achieve online mounting and dismounting and online maintenance, dispenses with additional special tools for mounting and dismounting, and has the advantage of convenience for operation.

Description

Interior top formula compound seal forged steel top dress ball valve
Affiliated technical field
The utility model relates to universal machine valve technology, belongs to the transformation of top dress ball-valve structure, and it plays a kind of medium of opening or close on pipeline.
Background technique
Existing top dress ball valve mainly is made up of valve body, valve gap, spheroid, valve rod, valve seat supporting, valve seat, valve seat transposition assembly, filler, double-screw bolt, nut etc.The structural type of its valve seat is general common three kinds: having first kind of structure now is unidirectional stroke valve seat construction, is to adopt the mounting or dismounting double-screw bolt to be given up the throne from spheroid realization valve seat in valve seat supporting top, so that spheroid is installed.The dismounting double-screw bolt that just comes loose after spheroid installs so push valve seat to spheroid by the valve seat support spring, is blocked screw with the shutoff screw at last.Existing second kind of structure is two-way double-stroke valve seat construction, and it is by the double-screw bolt of giving up the throne valve component to be pushed up to two outsides, so that spheroid is installed.Behind the spheroid of packing into, by one group of wedge shape stationary axle assembly valve component is fixed to the working position again.More than two kinds of structures all compare concision and compact, but first kind of structure is suitable for heavy caliber top dress ball valve.These two kinds of structures all need from the valve peripheral operation simultaneously, must increase position, perfoliate technological operation hole, can increase the risk that leaks outside like this; In addition, their valve seat all adopts plastic seat such as PTFE or NYLON, is easily caused seal failure by the rigid impurity scuffing in the medium.The third is that elastic collar stop bit valve seat keeps coil structures.It is to adopt the valve seat retaining ring to entangle valve component to fix, and keep ring flat-plate to both sides valve seat by the special-purpose valve seat frock of giving up the throne, so that pack spheroid into, after spheroid is packed into, with special tooling the valve seat retaining ring is pulled to spheroid with valve component again, to be enclosed within elastic collar on the valve seat retaining ring cylindrical afterwards more in advance and pack in the draw-in groove, just take off special tooling, refill assemblies such as joining valve gap at last.This structure is from the valve internal mounting or dismounting, does not have the extra mounting or dismounting auxiliary hole that increases, and reduces the passage of internal leakage, has reduced the risk that leaks outside.But shortcoming is to have increased O-ring seals, and this has just increased the risk of interior leakage.The valve seat retaining ring of Zeng Jiaing and the increasing of valve body cause cost of material to increase simultaneously, and Economy is not good.The special tooling that is adopted can not keep the symmetrical application of force of circle to valve seat, therefore assembles and disassembles difficulty and strengthen; Its valve seat is plastic seat such as the teflon that adopts or nylon in addition, is easily scratched by the rigid impurity in the medium and causes seal failure.
Summary of the invention
The purpose of this utility model is to avoid above-mentioned deficiency of the prior art, provide a kind of applicable to different bores, pressure, the mounting or dismounting of its product are carried out from valve internal, do not need any special tooling just can install and remove valve easily again and sealing reliability is greatly improved interior top formula compound seal forged steel top dress ball valve.
The purpose of this utility model realizes by following technical measures: top formula compound seal forged steel top dress ball valve includes valve body, valve gap, spheroid, valve rod, valve seat supporting, valve seat, spring, gland, tie-plate, filler, O-ring seals in this, its innovation part is to be set with spring seat on the back cylindrical of valve seat supporting, has on the cylindrical of spring seat simultaneously and is used for installing the annular groove of splitting snap ring.In addition, be screwed the snap ring maintainance block on the front-end face of spring, it will be split snap ring and steadily protect.
The utility model beneficial effect compared with prior art is that the mounting or dismounting by this valve are from valve internal, again without any need for special special tooling, thereby avoided the appearance of leakage point, improved the sealing reliability of this valve, simultaneously it can be implemented in and traditional thread bindingly tear open and safeguard to have advantages of simple operation.
Description of drawings
Fig. 1 is a structural drawing of the present utility model.
Fig. 2 is a valve component partial enlarged drawing partly among Fig. 1.
The figure number explanation:
1, valve body 2, O-ring seals 3, valve seat supporting 4, spring seat 5, split snap ring 6, spring 7, snap ring maintainance block 8, socket head screw 9, valve seat 10, spheroid 11, grease pouring valve 12, safety check 13, sliding bearing 14, thrust bearing 15, thrust bearing 16, valve gap 17, O-ring seals 18, pad 19, socket head screw 20, gland 21, O-ring seals 22, filler 23, tie-plate 24, valve rod 25, key
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples: top formula compound seal forged steel top dress ball valve mainly is made up of valve body 1, valve gap 16, spheroid 10, valve rod 24, valve seat supporting 3, valve seat 9, spring 6, gland 20, tie-plate 23, filler 22, O- ring seals 2,17,21 etc. in this.At first suit upper spring seat 4 on the back cylindrical of valve seat supporting 3 has on the cylindrical of spring seat 4 and be used for installing the annular groove of splitting snap ring 5 simultaneously.During the assembling of this ball valve, be to go up from the valve top earlier spring seat 4 and valve seat are supported assemblies such as 3 to pack in the valve body 1.Reinstall spheroid 10 afterwards, and spheroid 10 got to closed condition, then from the valve internal operation, tighten socket head screw 8 on the spring seat 4 and valve component is pulled to spheroid 10 reach the seal operation position, and then pack in the annular groove on spring seat 4 cylindricals and split snap ring 5.Then earlier the inside door angle screw 8 on the spring seat 4 is taken off again, two snap ring maintainance blocks 7 of on the front-end face of spring seat 4, packing into and being symmetrically distributed, and be fixed with the socket head screw of before having unloaded down 8.The structure at this other position of valve and existing top dress ball valve are basic identical.
