Description
Technical field
The utility model be applied to gas transmission ＆ distribution field, more particularly to a kind of integrated buried solenoid valve box, the equipment can
It is used widely on gas transmission and distribution.
Background technology
With the development of science and technology and economic society, natural gas is widely applied, while anti-as gas safe
The gas emergency cut-off valve (magnetic valve) of important component also achieves extensive application in protecting system, realizes in accident condition
Lower cut-out gas supply, reduces dangerous effect.
Magnetic valve is more in actual applications to be used with forward and backward valve and by-passing valve and subsidiary pipeline composition solenoid valve block, just
The forward and backward valve of opens solenoid valve and by-passing valve often is closed when using, and the magnetic valve maintenance period closes forward and backward valve opening by-passing valve
To ensure continuous supply.
In practical application, based on a variety of causes, the design of gas pipeline generally lags behind building design, gas pipeline
Construction generally lags behind the construction of building again.The solenoid valve block of gas pipeline of being registered one's residence in practice of construction is generally placed in outdoor,
Majority leans on the exposed arrangement of wall, have impact on the overall appearance of building.There is following defect in solenoid valve block outdoor exposed：
1st, solenoid valve block pipeline and valve are unobstructed, influence building overall appearance；
2nd, the bright dress of front and rear valve there is a situation where easily to be supplied by artificial destruction without lock；
3rd, by-passing valve is easily illegally opened without control by people, and depositing magnetic valve in the state of accident and can not cutting off gas supply makes
Obtain the risk of warning system ineffective；
