Abstract
The utility model relates to a water checking dual-purpose valve, which provides a valve in valve which is provided with a spring voltage limiting drive plate, and the utility model is used for opening and closing the valves in a main pipeline and self-closing when water is cut off. The utility model is characterized in that a rotor plate and a core plug are arranged under a main spring in the inner chamber of a valve body, a water inlet is arranged beside the lower part of the valve body, and an auxiliary spring and a penetrated valve rod are arranged under the water inlet. The utility model has reasonable design, reliable performance and convenient operation, with adopting the valve in valve structure, the utility model both can self-close when water is cut off and can be used as a stop valve, and the utility model is an ideal pipe joint of hydraulic pipelines.
Description
The utility model relates to water valve, particularly stop valve and cutting off the water from the Water-checking dual-purpose valve of valve dual functions.
At present, self-closing valve under water-supply off is more, but is difficult to have practical product to appear on the market, and can not satisfy people's demand.
The utility model purpose provides a kind of Water-checking dual-purpose valve by spring pressure limiting drive sheet, is used for main pipe rail start or stop valve and water-stopping self-closing.
Water-checking dual-purpose valve comprises valve body 1, moving plate 3 and sealing gasket 15 etc., it is characterized in that main spring 6 is arranged at valve body 1 inner chamber top, and it is moving plate 3 and core plug 2 down, and side is provided with water outlet; Be provided with water intake in valve body 1 lower lateral, it is down auxiliary spring 8 and the valve rod 7 that penetrates.
This Water-checking dual-purpose valve, emphatically practicability and durability Design, employing be the pressure effect, as the power of power on the figure moving plate 3 and spring 6, use than driving core plug 2 this part is slided up and down, under certain condition, valve rod 7 slips into and closes in the locked groove and reach the effect of closing, during Open valve, need pull-up valve rod 7, make hydraulic action on moving plate 3, removal external force valve opening same as above, this work is all carried out under air-tight state, has only water intake and water outlet, outside leakage situation can not occur.
The dynamic structure working principle:
When water enters to the valve body lower portion side, artificial pull-up valve rod 7, current enter in the active chamber, when pressure during greater than 0.02-0.04MPa, pressure acts on moving plate 3 interlocks upwards, slide at the glissile segment of core plug 2 in valve rod 7 ends, valve opening, water outlet flowing water is normal, when pressure during less than 0.02-0.04MPa, pressure acts on power on the moving plate 3 less than spring force, core plug 2 and moving plate 3 interlocks slip into valve rod 7 ends and close in the locked groove, even pressure is greater than 0.04MPa downwards, valve rod 7 is pinned by groove can not open the effect that reaching thus cuts off the water supply closes; When pressure during greater than 0.02-0.04MPa, for pull-up valve rod 7 acts on power on the moving plate 3 greater than spring 6, core plug 2 interlocks of moving plate 3 upwards, slides on core plug 2 in valve rod 7 terminations, removal external force late gate is also at the state of opening, flowing water is normal.
When water pressure during greater than 0.02-0.04MPa, when wanting to close this valve,, to do the power that is used in moving plate 3 and make pressure cap 5, link rod 4, moving plate 3, core plug 2 simultaneously downwards as long as add that on pressure cap 5 external force makes external force add spring force greater than pressure, valve rod 7 terminations are slipped into and are closed in the locked groove.Pressure is opened in opening state with top described valve during greater than 0.02-0.04MPa, and flowing water is normal.
For preventing that water outlet is greater than water inlet, valve arrangement is to have one section to manufacture valve plug configurations and water outlet position on the core plug 2 in the employing valve, according to pressure condition, adjusts water flow automatically, keep the pressure in the active chamber true and reliable forever, make this valve keep normal working forever.
When pressure during less than 0.02-0.04MPa, but the people is a pull-up valve rod 7, is opening state, continues flowing water, and removing external force is that closed condition can not flowing water.
The utility model is reasonable in design, reliable performance, practical, easy to use, adopts valve arrangement in the valve, can water-stopping self-closing, and can be the desirable pipe fitting of conduit pipe as stop valve again, be suitable for penetration and promotion.
The utility model accompanying drawing is a structural representation, wherein valve body 1, core plug 2, moving plate 3, link rod 4, pressure cap 5, main spring 6, valve rod 7, pair spring 8, pad 9, nut 10, bonnet 11, valve rod base 12, seat cap 13, O type circle 14, sealing gasket 15.
