Embodiment 1

[0060] Such as Figure 1 ~ Figure 2 As shown, a household gas pipeline safety monitoring system according to the present invention includes a pressure detection valve 1, a pipeline solenoid valve 4 and a controller. The controller is connected with the pressure detection valve 1 and the pipeline electromagnetic valve 4 respectively. The controller is used for controlling the action of the fixed solenoid valve, specifically, controlling the channel opening and closing of the pipeline solenoid valve 4 and controlling the pipeline solenoid valve 4 to lock the closed channel. At the same time, the controller receives the alarm signal from the pressure detection valve 1, controls the passage of the pipeline solenoid valve 4 to close, and controls the pipeline solenoid valve 4 to lock the closed passage.

[0061] Specifically, the pressure detection valve 1 includes a valve body, a diaphragm 11 , a first pressure balance mechanism 3 and a second pressure balance mechanism 2 . The ...

Embodiment 2

[0079]The safety monitoring system of a household gas pipeline described in Embodiment 2 has a structure similar to that of Embodiment 1, and the principle is the same. Specifically, the pipeline solenoid valve is described:

[0080] The pipeline solenoid valve 4 includes a hollow pipe body 41 , a sealing assembly 42 and an electromagnetic driving assembly 43 .

[0081] Such as image 3 As shown, specifically, the inner wall of the hollow tube body 41 has a stepped structure, so that the inside of the hollow tube body 41 has a first cavity and a second cavity parallel to each other. Both the first cavity and the second cavity are cylindrical cavities, and the diameter of the first cavity is larger than that of the second cavity; the boundary plane between the two is the stepped platform of the stepped structure, which is an annular .

[0082] The sealing assembly 42 includes a magnetic metal part 421 and a sealing rubber pad disposed on the magnetic metal part 421 . The out...

Abstract

The invention discloses a safety monitoring system for household gas pipelines. The safety monitoring system comprises a pressure detecting valve and a pipe electromagnetic valve connected with each other, and a controller connected with the pressure detecting valve and the pipe electromagnetic valve; the pipe electromagnetic valve is used for joining with a gas input pipeline; the pressure detecting valve is used for joining with a household pipeline; a cavity of the pressure detecting valve comprises an upper cavity and a lower cavity; the two cavities are isolated through a diaphragm, and are respectively provided with pressure balancing mechanisms; one ends of the two pressure balancing mechanisms butt against each other, and the two are positioned on the two sides of the diaphragm; the lower cavity is provided with two gas interfaces, and a rocking arm module for opening and closing the gas interfaces; and the rocking arm module is in driving connection with the pressure balancingmodule of the lower cavity. In a pipeline detecting state, even if the power is failed, although the pressure detecting valve cannot send an alarm signal, the pressure detecting valve still can detect if leakage occurs, and the pressure detecting valve can automatically close self channel.

Description

technical field [0001] The invention belongs to the technical field of gas safety monitoring, and in particular relates to a safety monitoring system for household gas pipelines. Background technique [0002] Existing household gas leakage alarms all adopt the method of sensing leaking gas and giving an alarm. This kind of gas leakage alarm has the following disadvantages: the reliability of the gas leakage alarm device is low, and the gas sensor for small leaks, Difficulty sensing. The charged alarm device itself is a source of danger in the case of gas leakage; leak alarms often cause false alarms. [0003] The Chinese invention patent "A Method for Leakage Detection of Indoor Gas Pipeline" with the notification number CN107606491 discloses a method for detecting leakage of an indoor gas pipeline and a pressure sensing device thereof. It installs a pressure sensing device in each indoor pipeline of the gas pipeline; closes the main valve of the corresponding household pi...
