Abstract
An automatic opening type frost valve. The valve is assembled by a valve body, a valve cap, a valve head and a micro-force spring, wherein the valve head and the micro-force spring are positioned inside the valve body, and the valve cap is arranged at the top of the valve body. When the tap water pipe is in the non-pressure state, the valve head presses the negative pressure of water refluence formation to oppress the micro-force spring and moves down, and the air gets into the water pipe, makes deposit water in the water pipe on the ground surface automatic converge the underground piping in, realizes from this that the automatic frost-proof purpose of converging of opening, the utility model discloses simple structure low cost, application scope is extensive, especially is suitable for vast rural anhydrous tower water supply system.
Description
The utility model relates to a kind of automatic-opening type frost valve, belongs to running water pipe equipment, and particularly suitable does not have the water tower water system.
At present; no water tower is adopted in vast rural area more; be interrupted and supply water; the free of frost phase; it is very convenient to supply water like this; but one to winter temperature decline, and cold weather (especially northern country) is after raw water service pump is shut down; whole water system is in passive state very soon; owing to do not have anti-icer on the running water pipe,, run into this kind situation so the frozen pipe phenomenon often occurs; have to roasting or scald running water pipe with boiling water with fire; when temperature descends suddenly, the water pipe from freezing crack phenomenon often occurs, bring worry and inconvenience to daily life; in order to overcome these deficiencies; the multiple anti-icer that is used for running water pipe has appearred on the market, but most of complex structure cost height, the automatic drainage type frost valve that Chinese patent CN92205887.3 announces is rational in infrastructure.But the size of float and pressure of supply water relation are bigger, and be very inapplicable in the place that ductwork pressure shakiness or water system pressure difference are bigger.
The purpose of this utility model is in order to overcome above-mentioned the deficiencies in the prior art part, to provide a kind of simple in structure, with low cost, the restriction that is not stressed easy to use, the automatic-opening type frost valve of good freezing protection effect.
The purpose of this utility model is that its structure outline that realizes like this is: it is by valve body, and bonnet, valve head, micro-force spring assemble, and valve head and micro-force spring are installed in the inside of valve body, and bonnet is contained in the top of valve body.
The purpose of this utility model can also realize that the utility model bonnet is provided with a center hole, and is processed with screw thread in order to finish automatic unlatching task effectively by following measure.
Compared to existing technology, it is easy to use to the utlity model has simple in structure and low in cost, advantages such as good freezing protection effect.Automatic unlatching of the present utility model is finished by micro-force spring, the sealing, earial drainage is effective and can adjust bonnet and micro-force spring pressure easily, to be suitable for the occasion of different pressure of supply waters, the utility model Applicable scope is extensive, especially is suitable for the no water tower water system in vast rural area.
Embodiment describes the utility model in detail below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present utility model
Fig. 2 is a scheme of installation of the present utility model
Valve body of the present utility model (1), bonnet (2) are made by plain cast iron, bonnet has a center hole on (2), valve head (3) is manufactured by plastics or nylon material, micro-force spring (4) is common spring, valve head (3) and micro-force spring (4) are installed in the valve body (1), fix with screw thread by bonnet (2), adjust spring pressure to be suitable for the water supply pipe system of different pressures by the precession and the back-out of bonnet (2) screw thread.The utility model such as Fig. 2 are installed in threeway (5) upper end of service pipe.When supplying water, because the effect of micro-force spring (4) closely fits together valve head (3) and bonnet (2), water can not be outflowed, the novel closed state that is of the utility model this moment can only be from user's water switch (7) outflow of opening.When water supply stops, the water of (6) example stream in the water pipe, form negative pressure, valve head (3) compressing micro-force spring (4) does not move, air enters pipeline (6) by the center hole of bonnet (2) and the gap of valve head (3), the automatic earial drainage of water in the water pipe (6) goes back, because anhydrous in the water pipe on top, ground, thus reached antifreeze purpose.
Claims (3)
1, a kind of automatic-opening type frost valve, it is characterized in that the automatic-opening type frost valve is assembled by valve body (1), bonnet (2), valve head (3), micro-force spring (4), valve head (3), micro-force spring (4) are positioned at the inside of valve body (1), and bonnet (2) is contained in the top of valve body (1).
2,, it is characterized in that having center hole on the bonnet (2), and be processed with screw thread according to the described automatic-opening type frost valve of claim 1.
3,, it is characterized in that valve head (3) is a cone according to the described automatic-opening type frost valve of claim 1.
