Embodiment

A kind of frost valve comprises the valve body 2 of glue system, unidirectional check Jiao Gai stifled 1.Establish the intake duct 4 of perforation in the described valve body 2, valve body 2 middle part peripheral hardware grooves 3 are from the taper structure 5 of groove 3 bottom valve bodies for ease of clamping in manage.Described unidirectional check Jiao Gai stifled 1 is stifled for convexity Jiao Gai, the one end is fixed on the set boss 7 of valve body 2 one sides, the fixing back the other end and plane, valve body top keep the dihedral elastic opening 6 of a setting, and its dihedral elastic opening 6 can close or open respectively when hydraulic pressure being arranged or do not have hydraulic pressure.Connect with water tap, discharging valve, pipe respectively by valve body middle part peripheral hardware groove 3 that the set hole 9 that coincide mutually with groove is fastened on the tube wall of the running water pipe 8 that links to each other, and valve body 2 is positioned at supplies water stream 10 by way of section, valve body 2 is downward, its top is positioned at running water pipe 8, the stifled dihedral elastic opening 6 of unidirectional check Jiao Gai flows 11 directions towards backwater, constitutes a kind of frost valve.Described frost valve is in round-the-clock water supply or locate low-lying charging pipe highway section, and it is stifled that the frost valve of installing is not established unidirectional check Jiao Gai, and intake duct changes into and drips 13 in its valve body.

Working principle

(see figure 3) when supplied water to the time period in the waterworks, frost valve is water flow velocity in running water pipe 8, and pressure of supply water makes the unidirectional check Jiao Gai stifled 1 on the frost valve produce pressure in the pipeline, along stream 10 directions that supply water close cover at intake duct 4 suitable for reading, blocking water supply stream prevents from leaking outside from intake duct 4, flow out from water outlet behind the commentaries on classics core of water process frost valve, various discharging valves, water flow velocity, water pressure are more big, and seal is more tight; When the waterworks will stop to supply water behind water stopping time, each resident family's running water pipe and pipeline do not have hydraulic pressure gradually, because water tap, discharging valve, water from gravity in the running water pipe, eminence produces backwater stream 11 to the running water pipe trickling of lower, just produce resorption power, the unidirectional check Jiao Gai stifled 1 that top one end of the frost valve installed on the areole is linked to each other is returning under the effect of original position opening force, make running water pipe outside air 12 be inhaled into (see figure 4) in the running water pipe 8 from the intake duct 4 on the valve body, cause water tap, discharging valve, pipe joint, water self-gravity action in the running water pipe, be back to rapidly in the underground water supply pipe (if do not enter air in the running water pipe, the water of the inside will staticly not flow), this moment water tap, discharging valve, pipe joint, be in anhydrous state in the ground running water pipe, each resident family's kitchen temperature is low more also to have no relations, and has just played the tap-water pipe defrosting effect.
