Abstract
The utility model relates to an actuating mechanism assembly with good sealing effect for a motor valve of an intelligent gas meter, comprising a valve body (2), wherein the top of the valve body is connected with a valve seal (1); the bottom of the valve body is connected with a main frame (7); the valve seal is connected with a rack frame (3); a rack (5) stretching downward is arranged on the rack frame; the rack is located in a corrugated tube (4); a spring (6) is arranged on the spring seat of the main frame; the spring is coated on the rack, and the upper end of the spring leans against the lower radial boss of the rack; the lower end of the corrugated tube (4) is embedded in the main frame; the lower end of the corrugated tube (4) is provided with a radially extending edge which extends outward and radially for the corrugated tube; the bottom of the radially extending edge for the corrugated tube leans against the top of the radially extending edge which is arranged on the bottom of the main frame and extends radially for the main frame; the radially extending edge for the corrugated tube leans against the lower end surface of the valve body. The actuating mechanism assembly for a motor valve of an intelligent gas meter is adaptive to the motor valve of an intelligent gas meter.
Description
Technical field
The utility model relates to intelligent gas meter and uses motor valve, the particularly intelligent gas meter actuator with the motor valve.
Background technique
A kind of driving execution mechanism that comprises tooth bar of existing intelligent gas meter motor valve is as shown in Figure 1, and it comprises valve body 2, and the valve body top is provided with jam pot cover 1; The valve body bottom is connected with body frame 7, is provided with seal ring 9 between body frame and the valve body, is associated with bellows 4 on the body frame; Be connected with rack frame 3 on the jam pot cover, rack frame is provided with down the tooth bar of stretching 5, and this tooth bar is positioned at said bellows; The spring seat of body frame is provided with spring 6, and overhead was below the radially boss of tooth bar on this spring was placed in tooth bar and spring.This mechanism, the sealing between body frame and the valve body is realized by lateral extrusion through said seal ring.Because valve body and body frame are difficult to guarantee the accuracy of radial dimension on processing and fabricating, circle is lacked of proper care, this is bad and leakage phenomenon occurs with regard to causing sealing effect easily.
Summary of the invention
The utility model will solve existing intelligent gas meter motor valve rack actuator and cause the problem of leaking because of sealing effect is not good enough easily; A kind of actuator assembly of the intelligent gas meter motor valve of the utility model is provided for this reason; This actuator assembly good sealing effect, and save material.
For addressing the above problem; The technological scheme that the utility model adopts is to be connected with jam pot cover at the valve body top, and the valve body bottom is connected with body frame, is connected with rack frame on the jam pot cover; This rack frame is provided with down the tooth bar of stretching; Tooth bar is positioned at bellows, and the spring seat of body frame is provided with spring, and this spring is placed in tooth bar and spring upper end and relies on below the radially boss of tooth bar; Its special way is that the underpart of said bellows is nested in said body frame; The bellows lower end has radially, and the bellows of extension radially prolongs edge; This bellows radially prolong below the edge by be pressed on the body frame lower end radially the body frame of extension radially prolong above the edge radially the prolonging above the edge of bellows by being pressed on the lower end surface of said valve body.
The utility model should be provided with the perforate convex tendon that bolt penetrates that is used for of evagination radially at said valve outer wall, and bolt passes the through hole of body frame and the perforate convex tendon of valve body is realized combining of body frame and valve body.
The utility model radially prolongs edge owing to the bellows lower end has; This bellows radially prolongs below the edge by being pressed on radially the prolonging above the edge of body frame lower end, radially the prolonging above the edge by being pressed on the lower end surface of valve body of bellows, so when body frame and valve body screw through bolt combine after; Bellows both sealed with body frame; With valve seal, guarantee good sealing effect again, avoid leaking and take place; So structure has also saved the seal ring that existing similar mechanism is adopted, even and body frame, the imbalance of valve body processing and fabricating circularity, do not influence sealing yet, have and save material and the effect that improves process industrial art performance.

Fig. 2 is the structural representation that comprises the utility model;
Fig. 3 is Fig. 2 structure and shape figure.
Be labeled as among the figure: 1 jam pot cover, 2 valve bodies, 3 tooth bar supports, 4 bellowss, 5 tooth bars, 6 springs, 7 body frames, 8 mechanisms, 9 seal rings, 10 perforate convex tendons.
Embodiment
A kind of actuator assembly of intelligent gas meter motor valve has valve body 2, and the valve body top is connected with jam pot cover 1; The valve body bottom is connected with body frame 7; Be connected with rack frame 3 on the jam pot cover, this rack frame is provided with down the tooth bar of stretching 5, and tooth bar is positioned at bellows 4; The spring seat of body frame is provided with spring 6, and this spring is placed in tooth bar and spring upper end and relies on below the radially boss of tooth bar; The underpart of bellows 4 is nested in said body frame; The bellows lower end has radially, and the bellows of extension radially prolongs edge; This bellows radially prolong below the edge by be pressed on the body frame lower end radially the body frame of extension radially prolong above the edge radially the prolonging above the edge of bellows by being pressed on the lower end surface of said valve body; Said valve outer wall is provided with the perforate convex tendon 10 that bolt penetrates that is used for of evagination radially, and bolt passes the through hole of body frame and the perforate convex tendon of valve body is realized combining of body frame and valve body.
Claims (2)
