Abstract

The utility model relates to a buoyancy-type automatic defect preventing water valve which belongs to valve techniques. The utility model is mainly used for automatically preventing large quantity of running water from running off when water supply works again due to forgetting to turn off a water valve which is turned on when water supply is cut off. The utility model is characterized in that the water valve is composed of water inlet and outlet flanges, a float, a connecting rod, a sealing plate, a hand-operated push rod with a handle, a reset spring, a valve port and a case body. The utility model has the advantages that the structure is simple, the float rises under the action of buoyancy to turn on the valve port normally and falls under the action of dead weight to automatically seal the valve port so as to ensure no loss of running water resulted from the turned on water valve which is not turned off when water supply works again after cut off, water resource is saved, water use accidents are avoided, installation and operation are convenient, etc.

Description

Buoyancy-type automatic defect preventing water valve

The automatic anti-error water valve of a kind of buoyancy type belongs to valve technology field, is mainly used in water supply pipe and prevents to open when cutting off the water water valve automatically and forget and close, and causes a large amount of loss tap water when coming water again.

In prior art, have only various switch water valves, Auto-delay switch water valve etc.Do not see to have to prevent from automatically when temporarily cutting off the water water tap opened and forget to close and cause a large amount of loss tap water when coming water again even flood ground, room toward lower floor's water valve of water story such as leak.And in the supply of tap water because the installation and the maintenance service in water route; it is inevitable that random of short duration cutting off the water appears in reasons such as insufficient water pressure is not enough; opening water valve as water user just at this moment finds anhydrous; want often to wait a moment intentionally and water valve does not cut out; the back of opening that also has is found anhydrously just to do other thing earlier and gone; forget and close water valve; especially the office space face come off duty before with water valve open find anhydrous do not close or not close extremely just come off duty away; could find when coming water can only arrive next day after walking again to come to work again; so not only a large amount of waste water resources, and regular meeting causes local floods.

It is a kind of simple in structure, easy to install that the purpose of this utility model is to provide, be contained in and prevent from automatically on the water supply pipe of switch water valve front switch opens not to be closed when temporarily cutting off the water, a large amount of loss tap water when coming water again, be beneficial to using water wisely, avoid occurring the automatic anti-error water valve of buoyancy type of water accident.

Basic principle according to buoyancy and water-stop, at the subject matter that exists in the prior art, basic design of the present utility model is: adorn a float in valve chest, this float is subjected to floating function when in the water supply pipe water being arranged, the moving connecting rod of last shipper pole moves synchronously with the sealing plate of fixedlying connected with connecting rod, makes the water valve normal open; There has not been buoyancy in the valve body when cutting off the water, float is together with the deadweight of connecting rod and sealing plate one cause and fall, sealing plate is sealed with valve port, although switch water valve is not closed when coming water again, because of this anti-error water valve that is positioned at the switch valve front stops water, so water can not flow out, have only with hand and upwards press the push rod that is located at band Returnning spring under the valve casing, sealing plate is upwards held up, this water valve is opened, float rises, and this water valve is in normally open again.

The automatic anti-error water valve of described buoyancy type that is characterised in that of the present utility model, by entery and delivery port flange, float, connecting rod, sealing plate, manual push rod, Returnning spring, valve port and the housing of band handle constitute; Above-mentioned float is loaded in the above-mentioned housing in the lump and can moves up and down under buoyancy and self-gravity action together after connecting rod and sealing plate are fixedly connected so that the opening and closing of fault valve port, form two of above-mentioned valve port "

" shape wall one falls one just be separately fixed at above-mentioned housing up and down on two walls; so that can be by the above-mentioned valve port of sealing plate sealing above forming for the plane; the manual push rod suit of above-mentioned band handle be loaded in the sealed pipe that above-mentioned housing protrudes downwards by seal washer behind the above-mentioned Returnning spring; whole water valve is loaded on the preceding pipeline of running water switch by above-mentioned intake-outlet flange.

The utility model has the advantages that: spool has only float, connecting rod and sealing plate, simple in structure, rising by buoyancy often opens valve port, by the whereabouts self closing valve mouth of conducting oneself with dignity, guarantees when temporarily cutting off the water switch opens do not closed and comes the water tap water that can not run off again, both conserve water resources, the water accident can not occur again, carry intake-outlet flange, easy for installation, needing only when coming after cutting off the water with hand upwards becomes normally open valve once this valve of manual push rod that pushes away the band handle again.

Accompanying drawing is the whole vertical profile front elevational schematic in the utility model most preferred embodiment assembling back.

1 water outlet flange among the figure, 2 floats, 3 connecting rods, 4 sealing plates, 5 water intake flanges, 6 manual push rods, 7 Returnning springs, 8 pusher grip, 9 valve ports, 10 housings.

Implement construction features of the present utility model further are summarized as follows with the best in conjunction with the accompanying drawings: the utility model product divides 3/4 "; 1 " " three kinds of specifications; be example only; the tubular float made from expanded polystyrene 2 and the sealing plate 4 of rubber circular plate matter; be placed in HT200 as spool and be processed in the housing 10 that carries intake-outlet flange 5 and 1 in the back together; the last inwall of this housing 10 has " ┑ " shape wall; following inwall has " a 7 " shape wall just with 1/2 by cylindrical connecting rod 3 fixed seal connections of duroplasts matter with first kind, the two has formed valve port 9, manual push rod 6 covers of the duroplasts matter band handle 8 cylinder bodily forms are loaded onto wire spring 7 backs and are packaged in the housing 10 downward pipes that protrude by packing ring, its upper end is relative with connecting rod 3, when being arranged, often opens in water by buoyancy valve port 9, by deadweight sealing plate 4 valve port 9 is sealed when cutting off the water, when coming water again with hand upwards moving push rod 6 valve ports 9 of a pushing hands often open again, push rod 6 resets by spring 7 simultaneously.

Change as present embodiment

1. the stock material shapes of each parts and external dimension can suitably change.

2. intake-outlet can only be established screw thread and is connected with water supply pipe by external flange.
