Abstract
The utility model provides a novel hydraulic type freeze-proofing valve which can be installed at a water outlet of the lowest point of each water level of a water pipe, the combination place between the water outlet of the water pipe and a water faucet, or the water pipe which is exposed and can be possibly frozen off. Particularly, the novel hydraulic type freeze-proofing valve comprises the following structure that a valve body is internally provided with an expansion device which is internally filled with the normal butane, the upper end of the expansion device is fixed at the inner side of the valve body by three screw nails with opposite angles with different directions, and the lower end of the expansion device is provided with a copper valve, and a water overflowing port is provided with a rubber seal ring and a guiding device which is used for guiding the expansion device. The normal butane which is filled in the expansion device is the liquid with the low boiling point, wherein the boiling point is minus 0.5 DEG C, and the normal butane in the expansion device is gradually cooled from the boiling and evaporating status when the outer temperature is reduced to be less than minus 0.5 DEG C, so that the expansion device starts to be shrunk, and the copper valve is gradually turned on, therefore, the water in the water pipe flows out from the water overflowing port and is hard to freeze since the water is positioned under the flowing status and the water pressure is also reduced, and the water pipe can not be frozen to be cracked caused by the temperature reduction. The novel hydraulic type freeze-proofing valve has the benefit effects of being safe, economic and high in practical applicability.
Description
Technical field
The utility model relates to valving, specifically is a kind of novel hydraulic type frost valve.
Background technique
Northern city in China; especially in the northwest, northeast winter cold area; the water pipeline that people use often can be damaged by frost; so not only have influence on people's daily water supply; but also caused very big economic loss; therefore people need a kind of valve urgently and can begin automatic draining when temperature drops to below 0 ℃, avoid the water frost crack pipe.Long-term exploration through the inventor, found that a kind of lower boiling liquid normal butane, its boiling point is-0.5 ℃, just in time near apparent freezing point, in case normal butane will change contraction state into by fluidized state when temperature was lower than below-0.5 ℃, produce the effect of expanding with heat and contract with cold according to the variation of external temperature.Yet normal butane except that as fuel and the refrigerant, is used to produce multiple organic synthesis raw material in a large number in industry at present, and its lower boiling physical property that approaches 0 ℃ is not by reasonable use.The purpose of this utility model is rationally to utilize this physical property of normal butane, and it is used as the power raw material of frost valve.Therefore, a kind of novel hydraulic type frost valve has just produced, and can satisfy people's needs.
Summary of the invention
The purpose of this utility model is for a kind of novel hydraulic type frost valve is provided, be installed in the junction of each water level minimum point drain opening place, water pipe water outlet and the water tap of water pipe, the perhaps Luo Lu water pipe place that might be damaged by frost solves cold winter water pipeline often by the problem of bursting by freezing.
A kind of novel hydraulic type frost valve of the utility model by: valve body (1), screw (2), expansion device (3), copper valve (4), rubber seal (5), pipe fitting silk (6), a normal butane (7) are installed, guiding device (8) is formed.It is characterized in that: expansion device (3) is installed in valve body (1), in expansion device (3), fill normal butane (7), the upper end of expansion device (3) is fixed on the inboard of valve body (1) with the diagonal angle screw (2) of three different direction, copper valve (4) is equipped with in the lower end of expansion device, and overflow is equipped with rubber seal (5).When outside air temperature during at normal temperature (more than 0.5 ℃), because the boiling point of the normal butane (7) in the expansion device (3) is-0.5 ℃, so normal butane is in the explosive evaporation state, the increased pressure of steam makes expansion device (3) be in extended configuration, copper valve (4) is squeezed on the rubber seal (5), forms closed state; When outside air temperature is reduced to below-0.5 ℃; normal butane in the expansion device (3) is lowered the temperature gradually by the explosive evaporation state; expansion device (3) is shunk; copper valve (4) is opened; water in the water pipe is flowed out by overflow, because the water in the water pipe is in mobile state, the hydraulic pressure in the water pipe is also reducing gradually simultaneously; therefore not-easy-to-freeze, the protection water pipe is not because of the cooling bursting by freezing.
Described expansion device (3) can be a kind of collapsible cylinder, and the normal butane of its interior splendid attire according to the variation boiling or the contraction of external temperature, thereby can be controlled its flexible unlatching and closure of controlling connected copper valve.
Described expansion device (3) can also be a kind of straight tubular cylinder, be provided with sealing plug in it, the lower end of sealing plug is connected with copper push rod valve, and outside extending to by straight tubular cylinder, the normal butane of the straight interior splendid attire of tubular expansion device cylindraceous (3), according to the variation boiling or the contraction of external temperature, sealing plug is flexible controls the unlatching of connected copper push rod valve with closed thereby make.
Described copper valve (4) can be a kind of valve of disc type.
Described copper valve (4) also can be a kind of valve of tapered.
Described copper valve (4) can also be a kind of valve of push rod.
It can be internal thread that described pipe fitting is installed silk (6), be installed in pipe fitting on the silk.
Described pipe fitting installation silk (6) also can be outer silk, is installed on the pipe thigh.
Described guiding device (8) can be a kind of guide wall, be installed in valve body (1) inboard neutral position and and the screw (2) at three diagonal angles be fixed on same direction place in order to the collapsible cylinder that leads.
Described guiding device (8) can be a kind of guide pipe also, and the lower end that is installed in straight tubular cylinder is passed copper push rod valve, comes it is played the effect of guiding.
The beneficial effect of a kind of novel hydraulic type frost valve of the utility model: the amount of the normal butane that charges in expansion device seldom ensures its Security; Do not need to drop into too much material for making of the present utility model, simple in structure, therefore have Economy; The utility model can be according to the caliber size of water pipeline; disposable installation is appropriate; do not need to carry out secondary operation; temperature variation automatic regulating valve door according to the external world; play the effect that protection water pipeline and pipe fitting are not damaged by frost; therefore have practicability, be fit to promote the use of at the northern area of China.
