Intelligent remote control electric valve powered by medium pressure gas battery

Abstract

The invention relates to an intelligent remote control electric valve powered by a medium pressure gas battery. An air inlet and an air outlet are formed in a valve body, a base is fixed on the valvebody, a main control board is arranged in the base, a wireless transceiver module is arranged on the main control board, a battery compartment is arranged in the base, and a low-voltage battery is mounted in the battery compartment; a pull rod is vertically arranged in the base, a diameter reducing section is arranged in the middle of the pull rod, a gasket connecting rod is connected with the lower end of the pull rod, a gasket assembly matched with a valve opening is connected with the lower end of the gasket connecting rod, a spring bracket is arranged outside the gasket connecting rod, anda spring is arranged between the spring bracket and the gasket assembly; and a clamping pin is arranged on the pull rod in a sleeving mode, a clamping slot matched with the diameter reducing sectionis arranged on the clamping pin, a through slot communicating with the clamping slot is further formed in the clamping pin, a deceleration motor is arranged in the base, and the deceleration motor isin transmission connection with a cam matched with the clamping pin. The intelligent remote control electric valve has the advantages that the structure is simple and reasonable, the safety and reliability are achieved, and gas path automatic cutting off can be achieved during the linkage with a gas alarm in case of gas leakage.

Description

technical field [0001] The invention relates to the technical field of gas alarm linkage devices, in particular to an intelligent remote control electric valve powered by a medium-pressure gas battery. The pressure range of the medium-pressure gas is 0.01MPa to 0.2MPa. Background technique [0002] The main component of gas is methane, and the main component of bottled liquefied petroleum gas is propane. When the concentration in the air reaches a certain concentration, it can cause people to suffocate and die. When the content reaches 5%-15%, deflagration will occur when encountering a fire source. Therefore, Gas leakage can cause great harm. [0003] With the development of social economy, people have higher requirements for their quality of life and living environment after meeting the basic needs of life. Unified installation of piped gas is not only convenient for fully enclosed management, although the safety of piped gas is much higher than that of bottled liquefied ...

Problems solved by technology

The description of the above method is complicated, not to mention the applicability

Moreover, most solenoid valves need DC9-12V power supply. Since the inductance of the internal coil of the solenoid valve is generally in the tens to tens of millihenries, the sparks generated by the energy stored and released when it is turned on and off cannot meet the national standard GB3836 for inductance. It cannot be used as an intrinsically safe circuit, so if it needs to meet the requirements, it needs to be flameproof or potted, so that the wireless communication and battery-powered functions can only be processed together with the battery and the circuit. , in addition to bringing great inconvenience to production, it also brings difficulties to use and maintenance
