Abstract
The utility model discloses an internal motor valve for a commercial meter gas. The original integral structure is changed to a split-type structure, that is, the original integral valve port bracket is changed to a combined type of a valve upper seat and a valve lower seat at present, so that the processing technology of components is effectively improved, the stability of the product quality can be guaranteed more favorably, and the processing cost and the integral cost of the product can be reduced. Meanwhile, three connecting bars are used for connecting the valve upper seat and the valve lower seat at present, and a valve bolt opens and closes a valve port through the movement of a connecting rod transmission mechanism. The internal motor valve has the advantages as follows: firstly, the valve bolt is not directly contacted with the connecting bars; secondly, the manner of the transmission structure of the valve bolt is improved, so that the valve bolt cannot be stuck, the transmission is stable, and the valve can be opened and closed reliably; and thirdly, a valve closing pivot point of the valve bolt is changed to the present three-point support of the three groups of connecting rod transmission mechanisms from the original one-point support of one screw rod , so that the vale bolt is not inclined during the movement process, and the stability and the reliability during the valve closing process is improved.
Description
Technical field
The utility model belongs to a kind of built-in valve of built-in valve, particularly a kind of gas meter.
Technical background
The publication number of the former first to file of the applicant is CN101551019, open day is on October 7th, 2009, a kind of built-in valve that provides in the patent application of " a kind of built-in motor valve that is installed in commercial combustion gas meter inside " is provided name, it does not directly contact with atmosphere, opening under the valve state, combustion gas enters gas meter inside by valve port, and itself has sealing gas meter, completely cut off atmosphere, effectively prevented the leakage hidden danger of combustion gas.But we find to exist following problem in actual applications, because bibcock is the embedded copper spare of moulding, make difficulty, it is eccentric to be easy to cause embedded copper spare of bibcock and cylindrical to exist, and bibcock is to slide on support when closing valve, when being very easy to switch valve occur like this bibcock and between stuck, switch valve is not in place, especially it is not in place to close valve, bibcock and support assembling simultaneously is also very difficult, and the support volume is bigger simultaneously, and manufacture difficulty is big, man-hour is long, the processing cost height.
The model utility content
The utility model provides a kind of built-in motor valve of commercial combustion gas meter, original overall structure is changed to assembled structure, help reducing difficulty of processing, improve the quality of products, directly driving close port to change into by jointed gear unit by screw rod original bibcock simultaneously drives, it is not in place to make that bibcock can not close valve when closing valve, has increased mechanism stability.
The technical solution of the utility model is: a kind of built-in motor valve of commercial combustion gas meter, comprise the valve bung flange, be provided with base in the valve bung flange, be fixed with motor on the base, motor connects headscrew by output gear, described valve bung flange is provided with the valve seat of honour, the valve seat of honour is fixed with an end of valve body connecting rod, the other end of valve body connecting rod is fixed on the valve base, be connected with the valve mobile plate on the valve body connecting rod, be connected with three groups of jointed gear units on the valve mobile plate, jointed gear unit one end connects the valve mobile plate, the other end connects bibcock, the bibcock front end is provided with valve port, and valve port is enclosed within the valve base, and jointed gear unit is connected with headscrew, motor rotates and drives headscrew, and headscrew drivening rod driving mechanism makes the bibcock lifting open and close the switch that valve port is realized valve.
