Abstract
The utility model relates to a kind of high-accuracy corrosion-resistant butterfly valve, comprise handle, valve body and valve plate, this valve body top mounting handle, this valve interior wall suit valve seat, silicon sulfide glue-line between described valve body and valve seat, be provided with valve plate in this valve seat, the valve seat inner edge that described valve seat contacts with valve plate is spheric structure.This butterfly valve improves manufacturing efficiency by upper and lower formula valve body structure, reduces costs; Make spheric structure by valve seat inner edge, reduce moment of torsion when valve plate rotates, improve the sealability of sealing valve plate; Valve plate and valve seat all adopt PTFE, improve corrosion resistance.The utility model structure is simple, design science rationally, be skillfully constructed, sealability is high, cost is low, has the value of wide popularization and application.
Description
Technical field
The utility model belongs to valve manufacture field, especially a kind of high-accuracy corrosion-resistant butterfly valve.
Background technique
The butterfly plate of butterfly valve is installed on the diametric(al) of pipeline.In the cylindrical channel of butterfly valve body, disc butterfly plate rotates around axis, and angle of swing is between 0 °-90 °, and when rotating to 90 °, valve is full-gear then, is closed condition when 0 °.
There is the problem of following aspect in tradition butterfly valve: 1, valve body is forward and backward two-part compositions, and linked together by the radial equally distributed multiple screw of circumference, the mounting structure of this valve body is loaded down with trivial details, wastes a large amount of manpower.2, in addition, when valve plate rotates and valve plate produce larger torsion, thus reduce sealability.3, usually at valve interior wall sulfuration one deck rubber gasket, the poor corrosion resistance of rubber, there is significant limitation Environmental Conditions aspect.
Through retrieval, find one section of patent documentation relevant to this patent content, publication number is the Chinese patent of CN202580053U, and which disclose a kind of high temperature resistant butterfly valve, comprise valve body, valve rod and seal ring, valve body is cylindrical, and built-in dish plate; Valve body is provided with stuffing box packing with valve stem contacts part.Described valve rod adopts external mounted rolling bearing.
By contrast, the valve body of above-mentioned patent publication us is forward and backward two-part compositions, has relatively big difference with present patent application in technological scheme.
Model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides that a kind of structure is simple, easy for installation, sealability is high, corrosion resistant high-accuracy corrosion-resistant butterfly valve.
Scheme of the present utility model is achieved in that
An efficient sealed Hand-operated butterfly valve, comprises handle, valve body and valve plate, this valve body top mounting handle, this valve interior wall suit valve seat, silicon sulfide glue-line between described valve body and valve seat, is provided with valve plate in this valve seat, and the valve seat inner edge that described valve seat contacts with valve plate is spheric structure.
And described valve body comprises upper valve body and lower valve body, and concrete structure is: the top connecting handle of this upper valve body, and this upper valve body underpart is semicircle arcuation and the arranged on left and right sides of its outer rim is integrally shaped with engaging lug; Described lower valve body is the semicircle arcuation corresponding with upper valve body, and the upper end portion outer rim arranged on left and right sides of this lower valve body is shaped with engaging lug equally, is linked together by upper and lower valve body by engaging lug.
And the inner edge of described upper and lower valve body is shaped with an annular groove.
Advantage of the present utility model and good effect are:
This butterfly valve improves manufacturing efficiency by upper and lower formula valve body structure, reduces costs; Make spheric structure by valve seat inner edge, reduce moment of torsion when valve plate rotates, improve the sealability of sealing valve plate; Valve plate and valve seat all adopt PTFE, improve corrosion resistance.The utility model structure is simple, design science rationally, be skillfully constructed, sealability is high, cost is low, has the value of wide popularization and application.
Accompanying drawing explanation
Fig. 1 is plan view of the present utility model;
Fig. 2 is that the A-A of Fig. 1 is to sectional view.
Embodiment
Below in conjunction with accompanying drawing, also by specific embodiment, the utility model is described in further detail.
A kind of high-accuracy corrosion-resistant butterfly valve, as shown in Figure 1 and Figure 2, comprise handle 1, upper valve body 2, lower valve body 9 and valve plate 4, described upper and lower valve body fastens up and down and is installed together, this valve interior wall suit valve seat 3, be sealed and installed with the valve plate of PTFE in the valve seat of this PTFE, the valve seat inner edge that described valve seat contacts with valve plate is sphere 7 structure caved inward, its effect reduces moment of torsion when valve plate rotates, and improves the sealability of sealing valve plate.
In the present embodiment, the structure of described upper and lower valve body is: the top connecting handle of this upper valve body, and this upper valve body underpart is semicircle arcuation and the arranged on left and right sides of its outer rim is integrally shaped with engaging lug 5; Described lower valve body is the semicircle arcuation corresponding with upper valve body, and the upper end portion outer rim arranged on left and right sides of this lower valve body is shaped with engaging lug equally, is linked together by upper and lower valve body by engaging lug.This mounting structure only needs two screws can complete the connection of valve body, not only improves installation efficiency, also saves cost simultaneously.
Silicon sulfide glue-line 6 between described upper and lower valve body and valve seat, improves the elasticity of valve seat, thus improves the sealability of whole valve.
The inner edge of described upper and lower valve body is shaped with an annular groove 8, its objective is the thickness having thickeied layer of silica gel, improves valve seat elasticity, and then improves sealability.
This butterfly valve improves manufacturing efficiency by upper and lower formula valve body structure, reduces costs; Make spheric structure by valve seat inner edge, reduce moment of torsion when valve plate rotates, improve the sealability of sealing valve plate; Valve plate and valve seat all adopt PTFE, improve corrosion resistance.The utility model structure is simple, design science rationally, be skillfully constructed, sealability is high, cost is low, has the value of wide popularization and application.
It is emphasized that; embodiment described in the utility model is illustrative; instead of it is determinate; therefore the utility model comprises the embodiment be not limited to described in embodiment; every other mode of executions drawn according to the technical solution of the utility model by those skilled in the art, belong to the scope of the utility model protection equally.
