Abstract
The utility model relates to an abrasion -proof ball valve valve holder structure contains valve body, spheroid, disk seat and O shape circle, installs the spheroid at the valve body internal rotation, has disk seat installation annular with system in the valve body at the spheroid contact position to have the disk seat coaxial with the runner in this collar inslot pressure equipment, the disk seat contacts for metal seal with spheroidal close cover position, go up the coaxial spacing O shape circle of installing at the radial contact surface middle part of disk seat and valve body, coaxial arrangement has a rubber circle between the axial contact surface of disk seat and valve body, and it has a radial bulge loop to make in the middle part of the outer peripheral face of rubber circle, coaxial arrangement has a packing ring between the axial contact surface of rubber circle and valve body. The utility model discloses valve long service life, sealing performance is good, effectively solves ball valve life weak point, the problem of easily revealing.
Description
Technical field
The utility model belongs to valve field, relates to ball valve, especially a kind of wear resistance ball valve valve seat construction.
Background technique
At present, the existing wear resistance ball valve valve seat back side adopts cylindrical spring pretension, and the solid granulates in medium is easily deposited on spring place, causes spring stuck, follows the string, and causes valve to leak.
Through retrieval, find the public technology of following analogous technical fields:
A kind of self tightening filler seal structure (CN204647401U) of ball seat, to comprise inside spheroid, valve seat, filler, valve seat filler pressure ring, dust ring, side valve body outside pressure ring, spring, valve seat filler; Described sphere installation is in valve seat, and valve seat is arranged in side valve body; Valve seat and side valve body connecting part are provided with filler by spheroid side, and opposite side is provided with dust ring; Inside described valve seat filler, pressure ring is connected with filler, and outside described valve seat filler, pressure ring is connected with dust ring, is provided with spring inside valve seat filler outside pressure ring and valve seat filler between pressure ring.The gap produced can be out of shape by auto-compensation filler, extend the working life of filler, the long period can keep excellent sealing effect, easy to operate, easy to maintenance, improve quality and the working life of valve.
A kind of sealing configuration (CN204061982U) of hard seal ball valve seat, comprise valve seat and the valve ball of ball valve, the sealing surface that valve seat contacts with valve ball cambered surface is interior concave circular arc, the interior concave circular arc of described sealing surface of seat is provided with the annular groove of multiple opening towards valve ball, sealing surface of seat is divided into several disjunct seal section by these annular grooves, the cross section of described annular groove is V-arrangement right angle groove, one cell wall of described V-arrangement right angle groove and valve seat axis parallel, another cell wall is vertical with valve seat shaft axis, the corner of each V-arrangement right angle groove notch is formed scrapes dirty sword.The utility model reduces the driving torque of ball valve, prevents dirty layer from affecting sealing effect, extends the working life of ball valve.
Comparative analysis is known, and published patented technology and known general knowledge all exist larger technology difference compared with present patent application.
Model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art part, there is provided that a kind of structure is simple, design science, good stability, the reliable wear resistance ball valve valve seat construction of sealing, be applicable to the wear resistance ball valve valve seat construction of graininess medium, and extend life of valve.
The utility model solves its technical problem and takes following technological scheme to realize:
A kind of wear resistance ball valve valve seat construction, comprise valve body, spheroid, valve seat and O shape circle, spheroid is rotatablely equipped with in valve body, with in the valve body of spheroid contact position, be shaped with a valve seat annular groove be installed, and be pressed with a valve seat coaxial with runner in this installation annular groove, valve seat and the sealing surface position of spheroid are that metal sealing contacts; On in the middle part of valve seat with the radial surface of contact of valve body, coaxial limit mounting has an O shape to enclose, and it is characterized in that: between valve seat and the axial surface of contact of valve body, be coaxially installed with a rubber ring, is shaped with a radial convex loop in the middle part of the outer circumferential face of rubber ring; A packing ring is coaxially installed with between rubber ring and the axial surface of contact of valve body.
And, in rubber ring inside, energy-storaging spring is installed.
Advantage of the present utility model and good effect are:
The utility model valve long service life, good seal performance, effectively solves ball valve short for working life, the problem easily revealed.
Accompanying drawing explanation
Fig. 1 is cross-sectional view of the present utility model.
Reference character represents: 1 spheroid, 2 valve seats, and 3O shape is enclosed, 4 rubber rings, 5 packing rings, 6 valve bodies, 7 energy-storaging springs.
Embodiment
Below in conjunction with accompanying drawing, also by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of wear resistance ball valve valve seat construction, comprise valve body 6, spheroid 1, valve seat 2 and O shape circle 3, spheroid is rotatablely equipped with in valve body, with in the valve body of spheroid contact position, be shaped with a valve seat annular groove be installed, and be pressed with a valve seat coaxial with runner in this installation annular groove, valve seat and the sealing surface position of spheroid are that metal sealing contacts;
On in the middle part of valve seat with the radial surface of contact of valve body, coaxial limit mounting has an O shape to enclose;
The innovative point of this structure is:
Between valve seat and the axial surface of contact of valve body, be coaxially installed with a rubber ring 4, in the middle part of the outer circumferential face of rubber ring, be shaped with a radial convex loop, between rubber ring and the axial surface of contact of valve body, be coaxially installed with a packing ring 5.Rubber ring is squeezed a valve seat to spheroid push-tight after installing, and play initial pretension, during work, pressure medium promotes seat compression spheroid further, realizes sealing.
In rubber ring inside, energy-storaging spring 7 is installed, increases the elasticity of rubber ring, extend the working life of sealing configuration.
Although disclose embodiment of the present utility model and accompanying drawing for the purpose of illustration, but it will be appreciated by those skilled in the art that: in the spirit and scope not departing from the utility model and claims, various replacement, change and amendment are all possible, therefore, scope of the present utility model is not limited to the content disclosed in embodiment and accompanying drawing.
