Abstract
The utility model relates to a large-aperture fixed type clamp sleeve heat insulation metal sealing ball valve which is applicable to pipeline control, belonging to the technical field of a valve. The valve has the innovative points that a valve body is designed into a bilaterally symmetrical structure according to the upstream and the downstream directions; a ball body is changed into a fixed type ball body; and a valve seat has a bilaterally symmetrical floating type metal sealing structure. The valve has the advantages of being low in operation torque, wide in aperture application scope, light in weight, long in service life, good in sealing effect, even in heat insulation and the like.
Description
Affiliated technical field
The utility model relates to universal machine valve technology, belongs to the improvement of chuck Thermal insulating ball valve.It is used for pipeline, plays a kind of medium of opening or close.
Background technique
The structure of existing chuck Thermal insulating ball valve has two kinds: a kind of is the floating type chuck Thermal insulating ball valve of soft seal, and another kind is the floating type chuck Thermal insulating ball valve of metallic seal.They all are made up of valve body, spheroid, valve rod, valve seat, insulation jacket, filler, screw etc.Its spheroid all is floating type, and operation is turned round the footpath with respect to fixedly the ball formula is bigger, and they can only be used for small-bore, and using scope is narrow.And it is all asymmetric about the valve body of existing these two kinds of Thermal insulating ball valves, so the insulation media between valve body and the insulation jacket often concentrates on the big left part in space, make the valve insulation inhomogeneous, when the fed sheet of a media flow velocity is blocked than slow or quilt, easily cause local retrogradation even aggegation, can have a strong impact on the sealability of valve like this, even destroy whole seal interface.In addition, the valve seat of the floating type chuck Thermal insulating ball valve of first kind of soft seal is the polytetrafluoroethylplastic plastic valve seat, and for the fed sheet of a media that the needs insulation could be flowed easily, viscosity is big or contain the medium of fiber, immobilized particles often, and the valve of plastic seat is very short its working life like this.The floating type chuck Thermal insulating ball valve of second kind of metallic seal is the downstream valve base sealing, can only seal in one direction, does not just have effective seal on another direction, so it is not suitable for the occasion that has two way sealed to require.
Summary of the invention
The purpose of this utility model is to avoid above-mentioned deficiency of the prior art, provide a kind of valve that can make to be incubated uniformly, can make this valve realize the function of two way sealed again, can also have the fixed chuck insulation of the heavy caliber metal seal ball valve of reliable sealing.
The purpose of this utility model realizes by following technical measures: the fixed chuck insulation of this heavy caliber metal seal ball valve consists predominantly of valve body, spheroid, valve rod, valve seat, valve seat supporting, insulation jacket, O-ring seals, filler, double-screw bolt, nut.Its innovation part is that at first valve body becomes left and right symplex structure by the upstream and downstream direction, and its valve shell and insulation jacket inwall form the uniform cylindrical cavity of left and right symmetry; Next is that the bottom of spheroid is positioned to fixed spheroid by lower valve rod; It three is that upper and lower valve seat part is a symmetric design, all be provided with the spring that pretightening force can be provided to valve seat on the inner side end of their valve seat supporting, its valve seat supporting is to carry out two-way stop bit by stop bit step on the valve body and snap ring to fix, and by lock ring and socket head screw snap ring and valve seat supporting is locked at last.
The utility model beneficial effect compared with prior art is owing to adopted the bidirectional metal sealing structure of spheroid means of fixation and valve seat, advantage such as make that it has that the operation moment of torsion is low, the bore scope is big, in light weight, long service life, good sealing effect, insulation are even.
Description of drawings
Accompanying drawing is a structural drawing of the present utility model.
The figure number explanation:
1, valve rod 2, packing press ring 3, socket head screw 4, filler 5, socket head screw 6, gland 7, O-ring seals 8, thrust bearing 9, lock ring 10, snap ring 11, O-ring seals 12, socket head screw 13, valve seat supporting 14, spring 15, O-ring seals 16, anti-fire ring 17, valve seat 18, insulation interface 19, spheroid 20, lower valve rod 21, blowdown plug 22, thrust bearing 23, drainage interface 24, drain plug 25, pad 26, bottom 27, double-screw bolt 28, nut 29, valve body 30, insulation jacket
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples: the fixed chuck insulation of this heavy caliber metal seal ball valve mainly is made up of valve body 29, spheroid 19, valve rod 1, gland 6, valve seat 17, valve seat supporting 13, spring 14, snap ring 10, lock ring 9, insulation jacket 30, O- ring seals 7,11,15, filler 4, double-screw bolt 27, nut 28 etc.Wherein valve body 29 is left and right symplex structure by the aspect, upstream and downstream.The inwall of the shell of valve body 29 and insulation jacket 30 forms the uniform cylindrical cavity of left and right symmetry, and the neck and the bottom of valve also be incubated, entry and exit with the insulation interface 18 of valve are arranged on the jacket wall of insulation jacket 30 with staggering simultaneously, make this valve obtain the insulation of effectively full side like this; And have additional lower valve rod 20 spheroid 19 is positioned to fixed spheroid in the bottom of spheroid 19; The valve seat 17 of this valve is a Structural Hardware in addition, its upper and lower valve seat is a symmetric form, all be provided with the spring 14 that pretightening force can be provided to valve seat on the inner side end of their valve seat supporting 13, its valve seat supporting 13 is to carry out two-way stop bit by stop bit step on the valve body 29 and snap ring 10 to fix, and is locked by lock ring 9 and 12 pairs of snap rings 10 of socket head screw and valve seat supporting 13 more at last.The valve seat of such upstream and downstream symmetric design just can reach the requirement of two way sealed.The structure at this other position of valve and existing chuck Thermal insulating ball valve are basic identical.
