Embodiment Construction

[0030] A built-in motor valve of a civil gas meter comprises a bracket, a base, a transmission assembly, a screw assembly and a valve plug assembly.

[0031] Such as Picture 1-1 with 1-2 As shown, the bracket includes a valve plug stop ring 1 and a fixed installation ring 2 coaxially arranged. The inner diameter of the valve plug stop ring 1 is smaller than the inner diameter of the fixed installation ring 2. The rail 3 is connected, and the inner wall of the slide rail 3 is provided with a chute 3-1; the fixed installation ring 2 is provided with a reed pipe installation frame 4, and the outer wall of the slide rail 3 is provided with a motor valve installation ear 3-2; the fixed installation ring 2 and the base The connection is secured by screws.

[0032] Such as diagram 2-1 As shown, the base 5 is provided with a motor box 5-1, a gear box 5-2 and an explosion-proof box 5-3. Motor 6 is arranged in the motor box 5-1, and the motor box cover 7 is threadedly connected wit...

Abstract

The invention relates to an internally installed motor valve of a gas meter for civil use. The existing products cannot meet various functional requirements. The internally installed motor valve of the gas meter for civil use comprises a bracket, a base, a transmission component, a screw component and a valve plug component, wherein a limiting ring and a fixed mounting ring of the bracket are connected through a slide rail and the fixed mounting ring is provided with a reed switch. A motor inside the base is arranged in a motor box, the transmission component is arranged in a gear box, and an anti-explosion plate is arranged in an anti-explosion box. An inner gear wheel upper cover, a limiting ring and an inner gear cover of the transmission component encircle to form a screw positioning cavity. A screw thread is formed in the outer wall of the upper part of the screw main body, and a clamping bump is arranged along the circumference of the waist part. The clamping bump is located in the screw positioning cavity and is linked with the transmission component through a spring and steel beads. The valve plug component comprises a valve plug base and a valve plug, and magnetic steel is embedded in the cylindrical wall of the valve plug base. The valve plug component can move up and down relative to the bracket. With the adoption of a split type structure, the internally installed motor valve of the gas meter for civil use improves machining manufacturability of parts efficiently, guarantees stability of product quality and reduces machining cot and total cost of products.

Description

technical field [0001] The invention relates to a valve, in particular to a motor valve in a civil gas meter. Background technique [0002] The motor valve used in the gas meter has very high requirements. First of all, in the case of ensuring the normal opening and closing of the valve, the lower the power supply voltage, the better, usually using weak current control; secondly, the operating current and power consumption of the motor valve must also be effectively controlled. Control, not too high; at the same time, the higher the valve opening height of the motor valve, the better, and it must meet the gas meter pressure loss requirements stipulated by the state. In addition, the sealing performance of the valve must meet the national standard. The motor valves currently on the market basically cannot meet all the above functional requirements at the same time. On this basis, the motor valves on the market control the valve switch by setting the time. Compared with the...
