Description

Carry by the formula water tap

The utility model relates to a kind of valve, particularly a kind of water tap.

At present, water tap commonly used all is knob type basically, also have and carry by formula, mainly contain valve body as Chinese patent 94238535.7 disclosed its structures, its have above inner chamber water outlet valve seat, spool have a core through hole, middle spool, open and close plug promptly the 3rd spool, valve rod, have the valve gap of conduit, in handle, seal ring, reach filter screen, valve nozzle etc.There is following deficiency in this water tap: have three spools, complex structure causes easily and leaks; When cutting off the water supply with water afterwards, below spool under the impact of water, very easily takeoff, promptly produce buoyancy, make water tap flowing water.

The purpose of this utility model provides carrying by the formula water tap of a kind of self pressure closes valve door that utilizes water.

The purpose of this utility model realizes by following measure: at the inner chamber of valve body, between the periphery and valve gap of valve seat, pertusate valve core tube on the wall is set, spool sidewall and the driving fit mutually of valve core tube inwall, can slide up and down, and in valve core tube, be connected with thick stem head; Be provided with a seal ring between the upper end of valve core tube and the valve gap, be provided with a seal ring between its lower end and the valve body.

When Water tap was closed, the hole location on the spool tube wall was in the side of valve core tube or/and be higher than spool.Spool is to be made of valve core case, cartridge cover, spring, and spring places in the valve core case, and valve rod passes the hole phase driving fit of the cartridge cover center of circle, and can slide up and down, and stem head is positioned at below the cartridge cover, withstands on simultaneously on the spring, is connected for spiral between cartridge cover and the valve core case.

The utility model is owing to have only a spool, so simple in structure, cost is low; Owing to set up pertusate valve core tube on the wall, when spool was positioned on the valve seat, the hole location on the spool tube wall was in the side of spool or/and be higher than spool, made spool that valve is had buffer seal power when water is arranged, and it can not leaked again; Spring in the spool makes spool that the seal force of spring force be arranged valve; Because valve seat is that seal ring is arranged on the valve, spool does not have the slit between them on valve seat the time, to the anti-multiple insurance of having leaked.Therefore spool is had only the pressure of water, do not have buoyancy of water, limit kind water tap water pressure resistance, the life-span is long, good seal, using scope is wide.

Below in conjunction with accompanying drawing the utility model is described in detail.

Fig. 1 is a half section schematic representation of the present utility model.

With reference to Fig. 1, valve body 10 has inner chamber, has the valve seat that raises up in the outlet port, on valve seat, be provided with rubber and open and close seal ring 4, the spool that is made of valve core case 5, cartridge cover 6 and spring 3 is positioned on the valve seat, spring 3 is in valve core case 5, and the thick stem head of valve rod 8 is positioned on the spring 3, and valve rod 8 passes cartridge cover 6; Middle center of circle hole, and phase driving fit can slide up and down, and are connected for spiral between cartridge cover 6 and the valve core case 5.On spool, be provided with a shockproof top 7 of rubber.A valve core tube 9 is set in the inner chamber of valve body 10, the centre of tube wall and a plurality of water flowing holes not of uniform size are arranged by upper end, lower end, spool sidewall and the driving fit mutually of valve core tube 9 inwalls, and can slide up and down relatively.Between the upper end of valve core tube 9 and valve gap 11, be provided with shockproof seal ring 12, be provided with seal ring 4 between lower end and the valve body 10, water can only be by the turnover of the hole on valve core tube 9 walls valve core tube 9, during valve closing, water has pressure to spool, and hydraulic pressure is big more, and valve closes tightly more, promptly utilize self pressure of water, play the effect of throttle down.During no hydraulic pressure, the rebounding force of spring 3 plays the effect of throttle down.Spring 3 also plays the resilience antihunt action of hydraulic pressure when opening simultaneously; The rebounding force closing function can be played again when closing, therefore water leakage phenomenon can be do not produced.For spiral is connected, positioning ring 13,16 being arranged in the conduit of valve gap 11 between valve gap 11 and the valve body 10, is that valve rod 8 is located up and down, and valve rod 8 has seal ring 17 by conduit outlet place pass-out between inboard valve rod 8 of conduit outlet and conduit.Handgrip by the location cover 14, handgrip covers 15, fixed plate 18 constitutes.14 peripheries that are enclosed within valve gap 11 conduits covers in the location, can slide up and down, and there is hole at fixed plate 18 centers, and valve rod 8 is hole pass-out and fix tightly thus, can not skid off, and place the conduit of valve gap 11 simultaneously and locate to cover 14 top.Handgrip lid 15 covers 14 with spiral with the location and is connected, with fixed plate 18, locate cover 14, the conduit of valve gap 11, seal ring 17, positioning ring 16 all cover within it.Valve rod 8 is in the conduit of valve core tube 9 and valve gap 11.Between the water outlet of valve body 10 and water outlet 1, be provided with filter screen 2, the current of the water outlet 1 that can flow slowly.

When water entered valve body 10, water can only be in the hole on valve core tube 9 walls flows into valve core tube 9, and water makes spool close the water outlet of valve tighter to the pressure of spool.If handgrip is upwards carried, then spool is put on by valve rod 8, promptly spool upwards slides in valve core tube 9, and when valve open, the hole of spool side exposed at its downside, water was promptly flowed out by water outlet 1 through valve therefrom.Hole on valve core tube 9 walls is in lacking that the spool downside exposes, and water flow is just little, hole the spool downside expose many or big, water flow is just big.When the firm shockproof seal ring 12 in 7 tops, the shockproof top of the rubber of spool, the water flow maximum.After handgrip pressed down downwards, spool was got back on the valve seat, was about to valve closing, and water is switched off.
