A filtering type floating solenoid valve structure for fire water supply

Abstract

The invention provides a filtering floating type electromagnetic valve structure for fire water supply. The filtering floating type electromagnetic valve structure comprises a valve body, a filtering device and a control valve. The valve body comprises an inlet end, an outlet end and a filtering end, and the inlet end and the outlet end are located at the two ends of the valve body respectively; the filtering end is located on the bottom face of the inlet end and is communicated with the inlet end; the filtering device is mounted inside the filtering end; the control valve is mounted on the top of the valve body; an exchange area is arranged in the middle of the valve body, and a containing interval is arranged inside the exchange area and is communicated with the inlet end; a communication pipe is arranged in the exchange area; and an opening is formed in the top end of the communication pipe, and the bottom end of the communication pipe is communicated with the outlet end. An abutting body is arranged to control vertical movement of a piston so as to control opening and closing of a water valve; and meanwhile, two-layer design is adopted in the piston, and a sealing layer on the top face is made of rubber materials and is good in sealing performance, not prone to being corroded and good in press fit alignment effect. A blocking body is arranged on the bottom face of the piston and can effectively prevent the water leakage condition caused by sliding of the piston from happening.

Description

technical field [0001] The invention relates to the technical field of fire-fighting equipment, in particular to a filter-type floating solenoid valve structure for fire-fighting water supply. Background technique [0002] In order to ensure fire safety, fire extinguishing equipment is usually installed in factories, exhibition centers, and terminal buildings. The fire extinguishing device is connected to the fire water inlet pipe through a solenoid valve. The existing water stop valve structure is generally through a movable water stop element. , to connect or block the water pipeline under different conditions. The opening and closing of the water stop element is controlled by the rotating mechanism set on the top of the fire water valve, which needs tools to complete, and the operation is inconvenient. Some fire water valves controlled by solenoid valves can automatically control the switch of the fire water valve through the solenoid valve, which is convenient and quick ...

[0002] In order to ensure fire safety, fire extinguishing equipment is usually installed in factories, exhibition centers, and terminal buildings. The fire extinguishing device is connected to the fire water inlet pipe through a solenoid valve. The existing water stop valve structure is generally through a movable water stop element. , to connect or block the water pipeline under different conditions. The opening and closing of the water stop element is controlled by the rotating mechanism set on the top of the fire water valve, which needs tools to complete, and the operation is inconvenient. Some fire water valves controlled by solenoid valves can automatically control the switch of the fire water valve through the solenoid valve, which is convenient and quick to operate, but at the same time, there is also a phenomenon that the valve core and the valve body are not well pressed and aligned. It is very easy to cause water leakage, which will not only waste water resources, but also be inconvenient to use, and there are various hidden dangers
