Problems solved by technology
One of the situations that is often overlooked by people is that when the gas is stopped, the gas appliances in the home are often still in use, but when the gas is stopped, they forget to turn it off
When the gas supply is restored, if the gas appliance is not turned off, gas leakage will occur at this time, so it is very dangerous

Embodiment Construction
[0015] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0016] Such as figure 1 As shown, the motor valve for the gas stop mechanical self-locking gas meter of the present invention includes a valve body 1, a valve core 2, and a motor 3; the valve body 1 has an air inlet 12, an air inlet cavity 13, and an air outlet 11. The valve core 2 is installed in the valve body 1, and the motor 3 is arranged on the valve body 1; the motor 3 is connected to the valve core 2 through transmission, and the valve core 2 controls the opening and closing of the air outlet 11; A gas detection device 5 is arranged in the air intake cavity 13;
[0017] The gas detection device 5 includes a piston cylinder 51, a piston 52, a spring 53, and a piston rod 54; one end of the piston cylinder 51 is airtight, and the other end communicates with the air intake chamber 13; the piston 52 is installed in the piston cylinder 51, so that On...

The invention discloses a motor valve for a gas meter capable of mechanically self-locking after gas stop, which is simple in structure, and is capable of realizing the purpose of mechanically detecting whether a gas inlet cavity has combustion or not. The motor valve comprises a valve body, a valve core and a motor; the valve body is provided with a gas inlet, a gas inlet cavity and a gas outlet, wherein the valve core is arranged in the valve body, and the motor is arranged on the valve body; the motor is in transmission connection with the valve core; the valve core controls the gas outlet to be opened and closed; a gas detection device is arranged in the gas inlet cavity; the gas detection device comprises a piston cylinder, a piston, a spring and a piston rod; a self-locking controller is arranged on the motor; a self-locking control button is arranged on the self-locking controller; the self-locking control button is triggered in such a manner that the piston rod extends to one side outside the valve body and shrinks. Due to the adoption of the motor valve, the phenomena that a gas appliance is forgotten to be turned off after gas stop and gas leakage is caused in case of supplying gas again can be avoided, and the safety of gas use is improved.
Description
technical field [0001] The invention relates to a motor valve, in particular to a motor valve for a gas stop mechanical self-locking gas meter. Background technique [0002] Known: natural gas leakage often can bring the loss of life and property to people, and the reason that natural gas leakage takes place has multiple, is generally pipeline leakage, gas switching valve damage etc. One of the situations that is often overlooked by people is that when the gas is stopped, the gas appliances in the home are often still in use, but when the gas is stopped, they forget to turn it off. When the gas supply is restored, if the burner is not turned off, gas leakage will occur at this time, so it is quite dangerous. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a motor valve for a gas stop mechanical self-locking gas meter that has a simple structure and can mechanically detect whether there is combustion in the intak...
