Abstract
The utility model is composed of a valve casing (1), a piston (2), a valve partition (3), a sealing gasket (4), a flow guide ring (5), a mandril (6) and a valve nozzle (7). The working process is that the valve nozzle (7) is held up by a hand, the piston (2) is jacked up through the mandril (6), water flows out from the water outlet of the valve partition (3), the water flows down along the outer wall of the valve nozzle (7) under the action of the flow guide ring (5), the valve nozzle (7) can be kept clean for a long time, the hand leaves the valve nozzle (7), and the water stops flowing out through the pressure in the water pipe. The valve has the advantages of sanitation, water saving, convenience, simple manufacture and difficult damage, and is particularly suitable for hospitals, laboratories and public places.
Description
It is water tap that the utility model belongs to tap water limit switch device, particularly tap water self-cleaning type contacting valve.
The water tap major part of each medical department and public place and laboratory use at present is outmoded unscrewing type valve.This valve must could be opened or close with handle in use, and handle places the valve outlet top, extremely difficult water flushing.Therefore, the pollutant that is trapped on the handle easily causes cross infection, is unfavorable for national health, and especially under the situation that needs sterile working or hygienic requirements strictness, the old-fashioned fire hose is inapplicable first watch.In recent years in the higher department of hygienic requirements, though have otherwise and the valve that closes, or because of the cost height, or because of using inconvenience, or can not generally apply because of fragile.
The purpose of this utility model is, overcomes above-mentioned shortcoming, provides a kind of tap water from the eliminant contacting valve.
Accompanying drawing is a mechanical construction drawing of the present utility model.
(1) is valve casing among the figure
(2) be piston
(3) be valve every
(4) be packing
(5) be guide ring
(6) be push rod
(7) be valve nozzle
Of the present utility model being characterised in that, one piston (2) is arranged in the delivery port of valve casing (1) front end, the front end of piston (2) contacts as ring-type with the delivery port of valve every (3), valve is connected with engage thread with valve casing (1) every (3), gap location seals with packing (4), guide ring (5) is fixed on valve every the front end of (3) with engage thread, and the front end of guide ring (5) has a valve nozzle (7), and a push rod (6) is equipped with on the top of valve nozzle (7). Piston (2) is void column shape in the upper shed, and front end is hemispherical. Valve nozzle (7) is taper, interior sky, round end. Said piston (2), its center borehole jack are on the guide pillar of valve casing (1), to limit the trend of piston (2). Valve nozzle (7) is connected valve by guide ring (5) on (3) with the mode of screw thread, valve nozzle (7) can move up and down in guide ring (5) and not come off, push rod (6) is equipped with in valve nozzle (7) top, and push rod (6) is coaxial with the guide pillar of piston (2) and valve casing (1). On valve nozzle (7) and inclined-plane that guide ring (5) contacts, two pairs of concavo-convex structures are arranged relatively, just can running water when holding up valve nozzle (7) and rotate a direction.
Working procedure of the present utility model is, when the valve nozzle that holds in the palm (7), by push rod (6), with piston (2) jack-up, water just flows out from the water outlet of valve every (3), valve nozzle (7) strengthens with the gap of guide ring (5) joint simultaneously, when current pass through the gap, since the leading role of guide ring (5), water just along valve nozzle (7) outer surface flow down and do not loose shallow, when closing, as long as hand leaves valve nozzle (7), by the pressure in the water pipe, piston (2) can automatically reset, and reaches the purpose of closing.Because the current of this valve are to flow down along valve nozzle (7) outer surface, in use, valve nozzle (7) is washed by water at any time, therefore, is difficult for adhering to dirt and keeps clean for a long time.
The utility model is except that packing (4) and piston (2), and all parts can be manufactured or manufacture with metal with duroplasts, and packing (4) and the available rubber of piston (2) or soft material are manufactured.
Characteristics of the present utility model are health, water saving, convenience and manufacture simply and not fragile, are specially adapted to hospital, laboratory and public place.
Claims (3)
1, a kind of tap water self-cleaning type contacting valve that comprises valve casing (1), it is characterized in that, one piston (2) is arranged in the water outlet of valve casing (1) front end, the front end of piston (2) contacts as ring-type with the water outlet of valve every (3), valve is connected with engage thread with valve casing (1) every (3), and gap location seals with packing (4), and guide ring (5) is fixed on the front end of valve every (3) with engage thread, the front end of guide ring (5) has a valve nozzle (7), and a push rod (6) is equipped with on the top of valve nozzle (7).
By the described tap water self-cleaning type of claim 1 contacting valve, it is characterized in that 2, piston (2) is void column shape in the upper shed, front end is a hemisphere.
3, by the described tap water self-cleaning type of claim 1 contacting valve, it is characterized in that valve nozzle (7) is taper, interior sky, round end.
