Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.
Referring to fig. 1-5, an embodiment of the present invention is shown: a selector valve with signal feedback comprises a self-locking pressure switch 1, a reset plug screw 2, a one-way valve 3, a valve body 7, a valve seat 8, a sensing element 9 and a proximity switch 10, wherein the proximity switch 10 is arranged below the valve seat 8, the sensing element 9 is arranged at the bottom of the valve seat 8 above the proximity switch 10, the valve seat 8 is arranged in the valve body 7, a pressure switch interface is integrated at the position, close to the outlet, of the valve body 7, the outlet of the valve body 7 is connected with an air outlet pipeline 5, the inlet of the valve body 7 is connected with an air inlet pipeline 6, the self-locking pressure switch 1 is installed at the pressure switch interface, the one-way valve 3 is arranged inside the self-locking pressure switch 1, the one-way valve 3 is connected with a selector valve 4, and the reset plug screw 2 is also arranged on the self-locking pressure switch 1; the proximity switch, the pressure switch and the relay of each selector valve are all connected with a controller 11, the controller 11 is connected with audible and visual alarms 12 of a plurality of protection areas, and the proximity switches of each selector valve are connected in series.
Notably, the proximity switch 10 is a magnetic proximity switch. Other types of proximity switches or non-contact switches are also possible.
In addition, the inlet pipeline of the selector valve 4 is connected with a fire extinguishing agent conveying pipeline, the selector valves 4 are connected with a controller 11 in an interlocking control mode, and the controller 11 is connected with a protection area audible and visual alarm 12.
The pressure signal feedback of the selection valve of the embodiment is integrated on the selection valve, the selection valve does not need to be installed on a pipe network behind the valve, and the pressure switch has the functions of self-locking and manual resetting.
The selector valve actuation of this embodiment may be piloted electric/direct electric/pneumatic/manual. The domestic selector valve is generally manual/pneumatic and is not electric; the pilot electric operation is to close the compressed gas input in front of the selector valve in the solenoid valve, the solenoid is powered on when the solenoid valve is started, the solenoid valve is opened, and the driving gas enters the driving cylinder at the top of the selector valve to open the selector valve.
The selector valve design is equipped with valve position (open entirely or close entirely) long-range supervisory function, and the system can monitor the valve state, and other selector valves are avoided opening simultaneously to the selection valve of interlocking simultaneously, cause and can't guarantee the concentration of putting out a fire and effectively put out a fire. The remote monitoring of the valve position (full open or full close) of the selector valve is realized by sensing the open-close position of a valve seat (installing a sensing element) through a non-contact proximity switch and feeding back the open-close state of the valve to a remote control cabinet.
The pressure switch is arranged on the valve body of the selector valve close to an outlet of the pressure switch, the pressure of an outlet blow-off pipe rises after the selector valve is opened, the pressure switch acts to feed back a pipe network pressure signal behind the valve, the pipe network pressure signal is self-locked and maintained through an internal one-way valve, and the pressure switch can be reset through the release of a reset screw plug. The pressure switch is a pressure signal feedback device on the gas automatic fire extinguishing system.
