Embodiment 1
[0020] Such as figure 1 with 2 As shown, a gas meter has a built-in flow control mechanism, which includes a main body 4 . The left part of the main body 4 is a cylinder, and the upper part of the cylinder is a trumpet-shaped opening. The right part of the main body 4 is a motor frame, and the motor frame is fixed with a drive motor 8 . A gear set 7 is arranged between the cylinder and the motor frame. The bottom of the cylinder of the main body 4 is connected with a round tube 42 , and the upper part of the round tube 42 is inserted into the cylinder to be sleeved with a spring 41 . The outer wall of the circular tube 42, the bottom of the cylinder and the inner wall of the cylinder form a spring chamber, and the spring 41 is arranged in the spring chamber. Spring 41 is stage clip, and the lower end is crimped with cylinder bottom. The bottom of the circular tube 42 stretches out from the bottom of the cylinder. The trumpet-shaped open end of the main body 4 is sealingl...

The invention provides a built-in flow control mechanism of a gas meter and relates to the technical field of gas meters. The main body of the built-in flow control mechanism is a cylinder provided with a horn-shaped opening. The horn-shaped opening end is in seal connection with a butterfly-shaped sealing piece. A lifting wheel is rotatably connected with the lower portion of the cylinder. The lifting wheel is provided with a spiral oblique face which serves as a lifting rail. The lifting wheel is connected with a driving motor through an arranged gear set. An inverted-T-shaped lifting shaft is inserted into the cylinder. A throttling sealing piece is connected to the upper end of the lifting shaft. The lower portion of the lifting shaft attaches to the lifting rail tightly. By the adoption of the built-in flow control mechanism, the technical problems that in the prior art, the control structure of a switch valve of a gas meter is large, a sealing piece is prone to being damaged and losing efficacy, and potential safety hazards exist are solved. The built-in flow control mechanism has the beneficial effects that the functions of flow transmission control, flow switch in-place detection and structure sealing are integrated, the structure is compact and reasonable, the number of parts is small, the assembling technique is simple, the production cost is reduced, and the efficiency is improved; the size of the gas meter is reduced, and flow control is reliable; damage to the sealing piece is low, and the potential safety hazards are eliminated.
Description
technical field [0001] The invention relates to the technical field of gas meters, in particular to a control structure of a gas meter switch valve. Background technique [0002] With the improvement of living standards, people also have further requirements for the supporting facilities of life. The gas meter is a mandatory gas trade settlement record form. People's requirements for it have risen from the original measurement accuracy and safe use to small size, less space, and intelligent meter reading for easy use. China Patent Authorization Announcement No. CN202451931U, authorized announcement date September 26, 2012, a utility model patent named "Electric Actuator for Intelligent Gas Meter Control Special Motor Valve", which provides an electric actuator for gas meter motor valve device. It includes a valve core assembly, a return elastic member and a driving mechanism; the valve core assembly includes a valve stem, a limit shaft vertically arranged at the top of the...
