Abstract
The utility model relates to a self-closing valve when the water supply is cut off, which is characterized in that a valve rod which can move in the vertical direction is assembled in the inner through hole of a valve cover, a spring is assembled on the valve rod, and a rubber pad fixed on the lower end of the valve rod can be matched with a valve seat to close the self-closing valve when the water supply is cut off; the lower baffle plate of a valve casing body is fixed on a water inlet part, an O-shaped sealing ring is assembled on the valve rod, and the lower end part of the valve rod is fixed with rubber pads by an upper and a lower clamping plates. The utility model has the advantages of good tightness, long service life, simple operation, and convenient maintenance; moreover, the valve casing body can use the existing valve casing body.
Description
The utility model relates to a kind of poppet valve, i.e. stopper, specifically a kind of self-closing valve under water-supply off.
In the daily life, running water switch and the regulating water-quantity all water tap of the sub-end of tube are manually finished.But can cut off the water suddenly for a certain reason sometimes, forget after water tap is opened and shut, leave home to go out, when coming water once more, current completely even are stretched downstairs, and the phenomenon that makes the wall immersion cause the neighbourhood to get along well happens occasionally.Disclose a kind of " the time Mo of cutting off the water closes; come behind the water Water stop valve tap automatically " for Chinese patent CN2168129 number, its main structure is to be provided with between water tap rear end and feed-water end that the dress ball float blocks up the lock cavity one in, though this structure can intercept water, but bulky, manufacture inconvenience.
The purpose of this utility model provides a kind of simple in structure, is convenient to manufacturing, the self-closing valve under water-supply off of long service life.
The purpose of this utility model can reach by following measure:
Valve chest is basic identical with the preceding total valve shell of the water meter that uses now, valve chest top assembling valve gap, the valve gap intermediate throughholes is assembled valve rod moving up and down, also be equipped with spring on the valve rod, the valve rod lower end is fixed with rubber cushion and does to cut off the water to close to cooperate with valve seat, valve chest install with the secure side of now having used to opposite, an end that promptly has lower pedal in the valve chest is the running water inlet place.The valve gap bottom is equipped with " O " type rubber seal contiguously with valve rod, the spill and leakage of anti-sealing.Valve rod lower end valve head rubber cushion is used die holder and is fixed.
Accompanying drawing and description of drawings:
Accompanying drawing is the self-closing valve under water-supply off cross-sectional view.
Among the figure: 1-valve chest, 2-valve seat, 3-valve head rubber cushion, 4-valve head punch holder, 5-valve head die holder, 6-valve gap, the 7-lower pedal, 8-valve handle, 9-valve rod, the 10-overhead gage, 11-packing ring, 12-spring, 13-" O " type circle, the 14-nut, the interior annular chamber that a chamber-valve chest, lower pedal, rubber cushion valve gap form, the space that b chamber-valve chest overhead gage and rubber cushion surround.
The utility model embodiment in conjunction with the accompanying drawings is described further:
Be the self-closing valve under water-supply off cross-sectional view as shown in drawings, valve chest 1 is with the preceding stop valve structure of installing of recycled water in family table is identical now, assembling valve gap 6 on the valve chest 1, unlike the prior art be, be equipped with valve rod 9 moving up and down in the valve gap 6 middle part through holes, the valve handle 8 that the useful nut 14 in the top of valve rod 9 is fixed, be with spring around the valve rod top that cooperates with valve gap, the valve gap bottom is added with the O type packing ring 13 of medical poisonless rubber material in case excessive leaking outside waterborne with the valve rod cooperation place, make spring not be subjected to etch, increase the service life.The rubber cushion of valve head bottom 3 of valve rod 9 is fixed with nut between valve head punch holder 4 and valve head die holder 5.
This valve still is installed in water meter when installing before, be in normally open when normally using.Hydraulic pressure descends when stopping to supply water, and the valve valve head descends under spring 12 thrusts and valve rod 9 self gravitation effects and closely contacts with valve seat 2.A cavity pressure increase sealing effect is better as shown in FIG. when secondary water-supply.As long as make progress poppet-valve handle 8, valve head will break away from valve seat when the user needed water, and valve head moves up and is parked in certain position, and water flows into the b chamber by a chamber, satisfies user's water.
If the water tap behind the water meter damages when needing to change, press valve handle 8 a chamber hydraulic pressure with hand and substantially exceed b chamber hydraulic pressure, valve head rubber cushion 3 closely contacts with valve seat 2, water can not flow into the b chamber, just cut off the water supply and play by effect, the user can change water tap relievedly, and only need mention valve handle 9 once more after maintenance finishes can normal water.
Water tap after the user is all water meters is closed, and when the water source, back that cuts off the water supplied water once more, self-closing valve under water-supply off just can be opened automatically without the hand control main valve.If there is a water tap not close or be not closed completely behind the water meter, this valve will cut out automatically.Its open theory be because of the initial water pressure that supplies water for the second time little, the specific pressure deficiency, water supply line is full of tap water behind b chamber and the b chamber before cutting off the water, and since water tap close the pipeline internal memory and stay water, because pond dew also can flow to the b chamber, the b chamber is full of tap water very soon, and a, b two chambeies are communicated with at this moment, and the sealing force of valve head rubber cushion 3 is eliminated, and at this moment hydraulic pressure act on valve rod 9 sealing surfaces, along with increasing of hydraulic pressure, piston thrust is greater than spring 12, and valve rod 9 drives the main valve head and opens automatically.If have a valve not close behind the water meter, or be not closed completely, the valve outlet port decompression, come water after hydraulic pressure in a and b two chambeies, produce pressure reduction, a chamber hydraulic pressure is greater than the b chamber, this moment, the main valve head played the one-way valve effect, cut off the water source behind the water meter, did not have water leakage phenomenon and took place.
