Abstract
The utility model discloses a motor valve sealing mechanism for an intelligent gas meter. The motor valve sealing mechanism comprises a valve rod, a thin-wall rubber part and a valve body, a valve port is arranged on the valve body, the thin-wall rubber part is a thin-wall rubber part with upper and lower openings, the lower end of the valve rod sequentially penetrates through the thin-wall rubber part and the valve port, the thin-wall rubber part comprises a thin-wall rubber part upper portion, a thin-wall rubber part middle portion and a thin-wall rubber part lower portion, an annular groove is arranged at a position, corresponding to the thin-wall rubber part upper portion, of the valve rod, the inner diameter of a cavity wall of the thin-wall rubber part upper portion is smaller than the outer diameter of the annular groove, a groove is arranged at a position, corresponding to the thin-wall rubber part lower portion, of the valve body, and the thin-wall rubber part lower portion is fixed in the groove. By arranging the annular groove and the groove for mounting the thin-wall rubber part on the valve rod and the valve body, pressure resistance of a dynamic valve sealing structure is improved, product production efficiency is improved, and the problem of ineffective sealing caused by glue ageing during gluing is avoided.
Description
Technical field
The utility model relates to a kind of sealing mechanism, particularly relates to a kind of electric motor valve for intelligent gasmeter sealing mechanism.
Background technique
What electric motor valve for intelligent gasmeter was used at present is all that thin-walled rubber carries out motive sealing, when thin-walled rubber is fixedly connected with valve rod with the motor valve valve body, mostly uses glue to carry out bonding.Adopt that glue is bonding exists following shortcoming: 1, curing time is longer fully, generally needs about 12 hours, needs special static ventilation to process; 2, cementability is not strong, can only bear less pressure; 3, production technology is comparatively complicated, is not suitable for production line operation, affects manufacturing efficiency; 4, to contain composition comparatively complicated for rock gas, is in for a long time to cause agingly in rock gas, may come off from the abutting edge.
The model utility content
The purpose of this utility model is that a kind of good seal performance, electric motor valve for intelligent gasmeter sealing mechanism simple in structure are provided in order to address the above problem.
The utility model is achieved through the following technical solutions:
a kind of electric motor valve for intelligent gasmeter sealing mechanism, comprise valve rod, thin-walled rubber parts and valve body, described valve body is provided with valve port, the thin-walled rubber parts that described thin-walled rubber parts is upper and lower opening, the lower end of described valve rod is passed described thin-walled rubber parts and described valve port successively, described thin-walled rubber parts comprises thin-walled rubber parts top, thin-walled rubber parts middle part and thin-walled rubber parts bottom, the described valve rod position corresponding with described thin-walled rubber parts top is provided with circular groove, the internal diameter of described thin-walled rubber parts upper chambers wall is less than the external diameter of described circular groove, the described valve body position corresponding with described thin-walled rubber parts bottom is provided with groove, described thin-walled rubber parts bottom is fixed in described groove.
When valve carries out the switch motion, valve rod carries out downwards and moves upward, when valve rod moves up and down, the thin-walled portion at thin-walled rubber parts middle part stretches and shrinks, but thin-walled rubber parts top is fixed with the relative valve rod in thin-walled rubber parts bottom and valve body, be not subjected to displacement, thereby realize sealing function.
Particularly, the chamber wall thickness on described thin-walled rubber parts top is greater than the chamber wall thickness at described thin-walled rubber parts middle part.
Particularly, the chamber wall thickness of described thin-walled rubber parts bottom is greater than the chamber wall thickness at thin-walled rubber parts middle part
As preferably, described thin-walled rubber parts is horn-like thin-walled rubber parts.
As preferably, described motor valve sealing mechanism also comprises pressing plate, and described pressing plate is close to the top of described thin-walled rubber parts bottom, and the lower end of described pressing plate and described valve body are welded to connect.
The beneficial effects of the utility model are:
By circular groove and the groove that the thin-walled rubber parts is installed is set on valve rod and valve body, increase the voltage endurance capability of valve movable sealing structure, improve production efficient, also avoided the problem of the aging seal failure that causes of the bonding middle glue of glue simultaneously.
