Abstract

The high temperature resistant stopcock of the utility model one insulation, be provided with a valve gap, described valve gap is connected and fixed by bolt and valve body, it is a four-way cavity in the middle part of described valve body, described four-way cavity is up and down respectively by plug seal, and described valve body top is fixed by nut and a gland, and described gland top is installed with a manual station, be connected interlock with a valve rod bottom described manual station, described valve rod is affixed through the plug top on gland and valve body top.The utility model is incubated high temperature resistant stopcock compact overall structure, and maintenance and installation is simple, and effectively can improve the temperature-resistance characteristic of stopcock by the stopper arranging insulation exotic material.

Description

Be incubated high temperature resistant stopcock
Technical field
The utility model relates to a kind of plug valve, and it is specifically related to the high temperature resistant stopcock of a kind of insulation.
Background technique
Stopcock is the rotary valve of closure member or plunger shape, makes the passway on valve plug identical with the passway on valve body or separate by 90-degree rotation, realizes a kind of valve opened or close.The shape of the valve plug of stopcock can become cylindrical or conical.In cylindrical valve plug, passage is generally orthogonal; And in cone-shaped valve plug, passage in echelon.These shapes make the structure of stopcock become light and handy, but also create certain loss simultaneously.Stopcock is most suitable for as cut-out and connects medium and shunting is suitable for, but according to the character be suitable for and the abrasion-resistance of sealing surface, sometimes also can be used for throttling, current existing stopcock complicated integral structure, so be badly in need of now solving the problem.
Summary of the invention
For the problems referred to above, the purpose of this utility model proposes a kind ofly to seal the high temperature resistant stopcock of insulation tight, rational in infrastructure.
The high temperature resistant stopcock of a kind of insulation, be provided with a valve gap, described valve gap is connected and fixed by bolt and valve body, it is a four-way cavity in the middle part of described valve body, described four-way cavity is up and down respectively by plug seal, and described valve body top is fixed by nut and a gland, and described gland top is installed with a manual station, be connected interlock with a valve rod bottom described manual station, described valve rod is affixed through the plug top on gland and valve body top.
Described valve rod is at gland and valve body link position place periphery by packing seal, and described valve rod is also connected with valve body upper end inner wall sealing by multiple O shape circle being positioned at filler bottom; Described valve rod axle journal place is by a plane bearing and valve interior wall Spielpassung.
The utility model is owing to taking above technological scheme, and it has the following advantages:
The utility model is incubated high temperature resistant stopcock compact overall structure, and maintenance and installation is simple, and effectively can improve the temperature-resistance characteristic of stopcock by the stopper arranging insulation exotic material.
Accompanying drawing explanation
Fig. 1 is the cross-sectional view that the utility model is incubated high temperature resistant stopcock.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in detail.
As shown in Figure 1, for the utility model is incubated the structural representation of high temperature resistant stopcock, be provided with a valve gap 1, described valve gap 1 is connected and fixed by bolt and valve body 2, it is a four-way cavity 11 in the middle part of described valve body 2, described four-way cavity about 11 seals respectively by stopper 3, described valve body 2 top is fixed by nut and a gland 8, described gland 8 top is installed with a manual station 9, be connected interlock with a valve rod 4 bottom described manual station 9, described valve rod 4 is affixed with stopper 3 top on valve body 2 top through gland 8.
Described valve rod 4 is sealed by filler 7 at gland 8 and valve body 2 link position place periphery, described valve rod 4 is also connected with valve body 2 upper end inner wall sealing by multiple O shape circle 6 being positioned at filler 7 bottom, and described valve rod 4 axle journal place passes through plane bearing 5 and a valve body 2 inwall Spielpassung.
The utility model is incubated high temperature resistant stopcock compact overall structure, and maintenance and installation is simple, and effectively can improve the temperature-resistance characteristic of stopcock by the stopper arranging insulation exotic material.
The utility model is only described with above-described embodiment; the structure of each parts, setting position and connecting all can change to some extent; on the basis of technical solutions of the utility model; all improvement of carrying out individual part according to the utility model principle and equivalents, all should not get rid of outside protection domain of the present utility model.
