A kind of heating water boiler water valve that can compensate for wear gap, it comprises valve body, valve gap and the spool interting in valve body and valve gap, spool top is hinged with handle by rotating shaft, pulling handle can prize spool and move up and down in valve gap, it is characterized in that: described spool lower end surface be provided with seal valve under the effect of spring by being pressed on weep hole, on spool between above-mentioned spring suit valve gap and seal valve, described valve gap upper-end surface is also provided with is with externally threaded boss, one adjustable cap is spirally connected and is fixed on this boss by internal thread, be applied to the pressure on weep hole by the adjustable spool of rotation adjustable cap.The beneficial effects of the utility model are: realize the compensation to seal valve wear extent by the distance of adjusting between adjustable cap and boss, make seal valve remain that best pressure is applied in drain opening, make it keep best seal, on the one hand, effectively prevent because of the generation of leaking, cause the wet and slippery caused potential safety hazard in ground and the water resources that cuts the waste.
Description
Technical field
The utility model relates to a kind of water valve, specifically a kind of heating water boiler water valve that can compensate for wear gap.
Background technique
At present, what on market, occur is various of the household electrical appliances such as drinking machine, hot-water bottle, water intaking for the convenience of the user, on drinking machine or hot-water bottle, be all provided with water intake valve (water tap), when user fetches water, only need to pull the handle of water valve, handle utilizes lever principle that the spool of water valve is upwards promoted, the seal valve that is simultaneously positioned at spool lower end separates with drain opening, just can realize the object of water intaking.When user stops after water intaking, valve core reset promotes seal valve by being pressed on intake under the effect of spring force, realizes the seal action to water valve.
But in existing water valve, spool is the working environment in high temperature humidity for a long time, when additional work, constantly wearing and tearing and extruding, are easy to cause seal valve atrophy.Meanwhile, spring is after long-term use, and elastic force disappears gradually, causes the underpressure to seal valve, is difficult to ensure the amount of deformation of seal valve.In addition, the hinged installation of spool top and handle, therefore it defines the stroke of spool, amid all these factors, when water valve used after a period of time, as easy as rolling off a logly causes poorly sealed closely, causes water valve to leak, waste water resource.
Model utility content
The purpose of this utility model is the shortcoming existing in order to overcome prior art, provide a kind of simple in structure, cost of production is low, long service life, after can effectively anti-water check valve long-time use because of wearing and tearing, aging and a kind of heating water boiler water valve that can compensate for wear gap of causing leaking.
The utility model object realizes with the following methods: a kind of heating water boiler water valve that can compensate for wear gap, it comprises valve body, valve gap and the spool interting in valve body and valve gap, spool top is hinged with handle by rotating shaft, pulling handle can prize spool and move up and down in valve gap, it is characterized in that: described spool lower end surface be provided with seal valve under the effect of spring by being pressed on weep hole, on spool between above-mentioned spring suit valve gap and seal valve, described valve gap upper-end surface is also provided with is with externally threaded boss, one adjustable cap is spirally connected and is fixed on this boss by internal thread, be applied to the pressure on weep hole by the adjustable spool of rotation adjustable cap.
Described seal valve is made by heat-proof silica gel material, and the worktable diameter of its lower end is greater than weep hole diameter.
Described boss and valve gap integral production form.
Described adjustable cap is formed by metallic plate punching, and its central position is provided with through hole string and is enclosed within on spool.
Described boss height is greater than 5mm, and thread depth is greater than 3mm
The beneficial effects of the utility model are: 1) simple in structure, cost of production is low, improve the market competitiveness.2) can realize the compensation to seal valve wear extent by the distance of adjusting between adjustable cap and boss, make seal valve remain that best pressure is applied in drain opening, make it keep best seal, avoid leaking, the water resources that cuts the waste, plays energy-conservation effect, and effectively prevent because of the generation of leaking, cause the wet and slippery caused potential safety hazard in ground, on the other hand, prevent that valve body from can not lock the contamination phenomenon that makes outside air enter producing in hot water box and occurring; 3) easy to adjust quick, long service life.

Fig. 2,3 is the utility model Standard figure.
Fig. 4 is the utility model structure sectional view.
Embodiment
Below in conjunction with accompanying drawing, the utility model structure is described further: a kind of heating water boiler water valve that can compensate for wear gap, it comprises valve body 1, valve gap 2 and the spool 3 interting in valve body 1 and valve gap 2, spool 3 tops are hinged with handle 5 by rotating shaft 4, pulling handle 5 can prize spool 3 and move up and down in valve gap 2, it is characterized in that: described spool 3 lower end surfaces be provided with seal valve 6 under the effect of spring 7 by being pressed on weep hole 11, above-mentioned spring 7 is set with on the spool 3 between valve gap 2 and seal valve 6, described valve gap 2 upper-end surfaces are also provided with is with externally threaded boss 21, one adjustable cap 8 is spirally connected and is fixed on this boss 21 by internal thread, be applied to the pressure on weep hole 11 by the adjustable spool 3 of rotation adjustable cap 8.
Described seal valve 6 is made by heat-proof silica gel material, and worktable 61 diameters of its lower end are greater than weep hole 11 diameters.
Described boss 21 forms with valve gap 2 integral productions.
Described adjustable cap 8 is formed by metallic plate punching, and its central position is provided with through hole 81 strings and is enclosed within on spool 3.
Described boss 21 is highly greater than 5mm, and thread depth is greater than 3mm.
Working principle: in the utility model, because this kind of water valve just uses in heating water boiler, belong to environment under low pressure, so compared with traditional water tap, its service behaviour does not have too large requirement to bearing capacity in requiring.So in order to extend the working life of spring and seal valve, avoid seal valve to reduce its working life because bearing too large amount of deformation.So on seal valve, applied pressure is very little in this class water valve, and by its amount of deformation of movement travel control of restriction spool.So in the time designing and dispatch from the factory assembling, the distance that is spirally connected between adjustable cap and boss is larger, makes the top of spool away from weep hole as far as possible.When after long-term use, after seal valve wearing and tearing and spring pressure decay, occur poorly sealed, while causing leaking.User only need rotate adjustable cap, increases the distance that is spirally connected of adjustable cap and boss, the distance between reduction spool lower end and weep hole.Reach the compensating action to wear extent, make seal valve there is enough pressure and cover on weep hole, ensure its sealability.
The adjustment mode simple and fast of structure in the utility model to seal valve, can operate without professional workforce, therefore it can effectively be avoided because water valve is because of the long-time water leakage phenomenon that causes wearing and tearing to cause that uses, extend water valve working life, avoid because changing trouble and the economic loss of water valve to user's moulding, therefore can extensively promote the use of.
