Problems solved by technology

[0002] The main valves currently used in deluge valve water spray fire extinguishing systems, automatic sprinkler fire extinguishing systems, and automatic opening and closing water spray fire extinguishing systems are opened by the conventional solenoid valve on the main valve. After the solenoid valve is powered off The main valve cannot be closed automatically, it can only be closed manually
In the prior art, the electric control part on the main valve is through the conventional electromagnetic valve on the main valve, and after it is energized and opened, it cooperates with the relevant anti-reset control system to achieve that the main valve cannot be automatically reset when the solenoid valve is powered off. Complexity and poor reliability, so it is necessary to propose a pressure relief anti-reset control solenoid valve

Embodiment Construction

[0011] A pressure relief anti-reset control solenoid valve, as shown in Figures 1 to 5, mainly consists of a fixed nut 1, a static iron core 2, an electromagnetic coil 3, a moving iron core spring connecting rod 4, a moving iron core 5, and a moving iron core spring 6 , static iron core sealing O-ring 7, moving iron core sealing rubber column 8, pressure relief chamber 9, valve body 10, filter screen 11, connecting body 12, manual pressure relief valve 13, anti-return spring 14, anti-reset shaft pin 15. An anti-reset handle shaft seal O-ring 16, an anti-reset connecting body 17, and a manual reset handle 18 are composed. It has electric opening and manual opening functions. After the electromagnetic pressure relief valve is electrically opened, it can be set as the anti-reset function according to the need, and the reset can only be completed manually at this time; it can also be set as the automatic reset function.

[0012] When the manual reset handle 18 of the solenoid val...

Abstract

The invention provides a pressure release anti resetting control electromagnetic valve, which has the functions of electric opening, manual opening, anti-resetting and automatic resetting. The anti-resetting function can only be completed by hand. The working voltage, the working pressure and the drift diameter of the electromagnetic valve are able to be designed freely based on uses; the invention is able to be used for several times.

Description

technical field [0001] The invention relates to a fire extinguishing system, in particular to a pressure relief anti-reset control solenoid valve, which is applied to a deluge valve and an automatic sprinkler system. technical background [0002] The main valves currently used in deluge valve water spray fire extinguishing systems, automatic sprinkler fire extinguishing systems, and automatic opening and closing water spray fire extinguishing systems are opened by the conventional solenoid valve on the main valve. After the solenoid valve is powered off The main valve cannot be closed automatically, it can only be closed manually. In the prior art, the electric control part on the main valve is through the conventional electromagnetic valve on the main valve, and after it is energized and opened, it cooperates with the relevant anti-reset control system to achieve that the main valve cannot be automatically reset when the solenoid valve is powered off. It is complex and has...
