Abstract
The utility model relates to a valve, particularly a self-controlled valve for water supply after water cutoff. The utility model comprises a valve body, a valve cap and a valve core. The utility model is arranged between a water source and a water tap. When water is normally supplied, the valve core floats on the water surface at the upper part of the valve body. When a pipe line stops supplying water, the valve core falls through self weight. When water-supply is recovered, if the water tap is forgotten to close, the valve core tightly seals water roads under the action of water pressure, so that the phenomenon of water overflow can not occur, and only small quantity of water flows out through small holes on the sidewall of the valve body. If normal water supply is needed, the water tap can be closed and then the valve core can float off to start the water road.
Description
The utility model relates to a kind of valve, particularly a kind of resupply on water cut-off internally piloted valve.
After the water tap that uses in water system is at present opened, in supply channel, can not close voluntarily when anhydrous, therefore such situation often takes place in some areas that often cut off the water or high-rise building: after water tap is opened, when in the pipeline when anhydrous, the user often forgets and closes and leave away, current cause waste incessantly after coming water, even flood takes place.
In order to address this problem; people have designed many solutions; chewing (CN86207694u), water supply saving valve (CN86200662u), no-voltage protection formula water as water-stopping self-closing water chews (CN86200894u) and does not have the self closing water tap of pressure (CN85203289u) etc.; though they can address this problem; but part all comes with some shortcomings; or complex structure, or operation inconvenience.
The purpose of this utility model is to provide a kind of simple in structure, easy to operate resupply on water cut-off internally piloted valve.
The purpose of this utility model realizes in the following way: the resupply on water cut-off internally piloted valve is made up of valve body, valve gap and spool, and valve body divides epicoele and cavity of resorption, respectively water receiving source and water tap.Epicoele and cavity of resorption communicate by through hole.Spool is installed in the epicoele and can moves up and down freely.Through hole in the bottom of spool and the valve pocket becomes drive fit, and it is hollow that spool can adopt lightweight material to make as plastics, rubber, nylon etc., so that can float on the surface easily.Valve gap is installed in the top of valve body by screw thread.Body wall has an aperture to connect the epicoele and the cavity of resorption of valve body.
The utility model is simple in structure, and is easy to operate, can solve the pipeline back water tap of cutting off the water and forget and close that the back water that resumes water supply promptly runs off wasting disadvantage in a steady stream.
Describe CONSTRUCTED SPECIFICATION of the present utility model in detail below in conjunction with accompanying drawing.
Referring to Fig. 1, the utility model is made up of valve body (1), valve gap (2) and spool (3), and valve body (1) and valve gap (2) are cast iron, and the two is by being threaded.Spool (3) is made hollow by polyolefin plastics, so that can bubble through the water column easily.Valve body (1) comprises the epicoele and a cavity of resorption that is connected water tap that connect the water source, and the two communicates by a taper hole.The sidewall of valve body (1) has an aperture to connect the epicoele and the cavity of resorption (as shown in Figure 2) of valve body (1).Spool (3) is installed in the epicoele and can moves up and down freely.The bottom of spool (3) is a cone, with valve body in taper hole become drive fit.After pipeline is cut off the water, spool (3) moves down under the effect of deadweight, closely cooperate with the taper hole in the valve body (1), again supply water when pipeline and forget when closing, spool (3) is sealed the upper and lower cavity path in the valve body (1) under the effect of hydraulic pressure, avoided the continuous wasting situation of current, as the need normal water supply, only need water tap is closed, at this moment, the water of valve body (1) epicoele constantly flows into cavity of resorption through the aperture of sidewall, when the hydraulic pressure of epicoele and cavity of resorption equated, spool (3) was at the floating function float downward, thereby opened the upper and lower cavity path, open water tap again, then water can flow out in a steady stream.
Claims (2)
1, a kind of resupply on water cut-off internally piloted valve that is used for water circuit system is characterized in that, is made up of valve body (1), valve gap (2) and spool (3); Valve gap (2) closely connects as one by screw thread and valve body (1) top; Valve body (1) comprises the epicoele and a cavity of resorption that is connected water tap that connect the water source, and the three communicates by a through hole, and the sidewall of valve body (1) has an aperture to connect the upper and lower cavity of valve body (1); Spool (3) is installed in the epicoele of valve body (1), and the interior through hole of its bottom and valve body (1) becomes drive fit.
2, a kind of resupply on water cut-off internally piloted valve that is used for water circuit system is characterized in that, spool (3) can adopt lightweight material to make hollow as plastics, nylon, rubber.
