Description

Anhydrous display fire hydrant

Technical field

The present invention relates to a kind of fire hydrant, particularly a kind of anhydrous display fire hydrant.

Background technology

The fire hydrant of fire-fighting fire extinguishing is presently used for, due to every aspect, it sometimes appear that the hidden danger without water；If fire hydrant does not have water, in fire hydrant outward appearance hardly possible also to see, it is unfavorable to fire-fighting fire extinguishing, it is a kind of can show fire hydrant whether with the presence of water anhydrous display fire hydrant turn into eliminate fire hydrant potential safety hazard the need for.

The content of the invention

The purpose of the present invention is to overcome the deficiencies in the prior art there is provided a kind of anhydrous display fire hydrant, for showing whether fire hydrant has water, eliminates and reduce the anhydrous potential safety hazard of fire hydrant.

The technical solution adopted in the present invention is：Anhydrous display fire hydrant, include discharging valve and fire-fighting joint, the water supply connector of discharging valve is provided with water display device, and water display device includes display screen and floating display device, display screen is tightly connected with water supply connector, and floating display device is installed in water supply connector；Display screen is provided with sealing die cavity, sealing die cavity is connected with the intake tunnel of water supply connector, sealing die cavity includes display die cavity and Clear View Screen, Clear View Screen is made up of transparent material, display type intracavitary is provided with anhydrous mark and alarm call number, anhydrous to be masked as Chinese " anhydrous " word and English " anhydrous " word, anhydrous mark and alarm call number is located at the first half of display die cavity；Floating display device includes ball float, the first guide rod, the first guide pin bushing and shutter, shutter is located at display type intracavitary, shutter is located at before anhydrous mark and alarm call number, first guide pin bushing is fixedly connected with the inwall of water supply connector, first guide rod is actively tied in the first guide pin bushing, and shutter is fixedly connected with ball float；Because water is transparent, there are the vision of water and anhydrous visual difference unobvious inside Clear View Screen, can clearly show that inside Clear View Screen there is water or anhydrous using anhydrous mark.

It is anhydrous display fire hydrant operation principle be：When using, the fire protection pipeline of the water supply connector of anhydrous display fire hydrant and running water pipe is connected, and make the center line of the first guide rod vertical with horizon, running water enters after anhydrous display fire hydrant, ball float in water supply connector overcomes the gravity of ball float, the first guide rod and shutter to rise in the presence of hydraulic pressure, and ball float drives shutter to rise to display die cavity The first half, shelters from the anhydrous mark and alarm call number of the display die cavity first half using shutter, people in Clear View Screen it cannot be seen that anhydrous mark and alarm call number, so as to judge there is water inside anhydrous display fire hydrant；When it is anhydrous display fire hydrant in it is anhydrous be passed through after, ball float and shutter are moved down under the Action of Gravity Field of itself, shutter drops to be stopped declining behind the lower half of display die cavity, shutter drops to behind the lower half of display die cavity, shutter have left the position for blocking anhydrous mark and alarm call number, people can see anhydrous mark and alarm call number in Clear View Screen, so as to judge anhydrous inside anhydrous display fire hydrant；And maintenance is contacted by alarm call number.

The beneficial effects of the invention are as follows：Anhydrous display fire hydrant, provided with water display device, people can observe whether fire hydrant has water in the water display device of anhydrous display fire hydrant, just in case fire hydrant is anhydrous, water display device shows alarm maintenance dialogue, people can notify maintenance department to come to repair immediately per capita, reduce the leak that fire-fighting is checked, eliminate the anhydrous hidden danger of fire hydrant.
