Abstract

The utility model relates to a full-automatic intermittent water supply valve. A piston is arranged in the casing, and a spring is arranged below the piston. A sealing rod having two sealing gaskets are arranged in a lower valve body, and a press cap is arranged on the upper sealing gasket. The press cap and the lower valve body form screw connection, and a spring is arranged between the press cap and the upper sealing gasket. The upper end of the sealing rod is hinged with a piston rod through two connecting rods. The bottom of the lower valve body is provided with a small hole, and a pipe communicated with the upper part of the casing is arranged at the small hole. Under the function of water pressure, the automatically intermittent water supply can be realized by the utility model, and a large amount of water resource can be saved. The utility model has the advantages of no need of manual control and adjustment, simple structure, no easy wear part, long service life and without maintenance.

Description

Full-automatic intermittent formula supplying valve

The utility model is a kind of supplying valve, is a kind of full-automatic intermittent formula supplying valve specifically.

Now owing to there is not batch (-type) supplying valve simple in structure, automatic liquid supply, so in some place, adopt the valve control porous drain flushing of rotating open-close mostly as the public lavatory urinal, so that or wash the untimely health that influences, or valve is not closed the waste that causes water resource, stopcock is easy to damage in addition, existingly a lot keeps in repair untimelyly because of valve damages, and causes the phenomenon of perennial draingage.

The purpose of this utility model provides a kind of novel valve, and it can overcome existing shortcoming in the prior art, and batch (-type) supplies water automatically, and is simple in structure, not fragile.

The purpose of this utility model is achieved in that it comprises the housing of upper end closed, it is characterized in that being equipped with the following valve body that has inlet and liquid outlet in the housing lower end, piston is housed in the housing, and under piston, spring is housed, in the following valve body seal bar is housed, be installed with on the seal bar, following two sealing mats, on last sealing mat, pressure cap is housed, thread connection between pressure cap and the following valve body, between pressure cap and the last sealing mat spring is housed, by two rod hinge connections, following valve body bottom has aperture between seal bar upper end and the piston rod, and be equipped with conduit and communicate with housing top at the aperture place.

The valve rod that aperture is closed is installed at aperture place at following valve body, then can make to the utlity model has by function.

The utility model can realize that automatic batch (-type) supplies water under the effect of water pressure, not only can save great lot of water resources, and need not Artificial Control and adjusting, and simultaneously simple in structure do not have vulnerable part, so long service life need not keeped in repair.

Below in conjunction with embodiment and accompanying drawing thereof the utility model is described in further detail.

Fig. 1 is the structure sectional view of the utility model embodiment one.

Fig. 2 is the structure sectional view of the utility model embodiment two.

Fig. 3 is the A-A sectional view of Fig. 2.

With reference to Fig. 1,1 is housing among the figure, piston 2 is housed in housing, have piston rod 16 on the piston, one end of spring 3 withstands on below the piston, the other end withstands on housing bottom, valve body 7 is housed down below the housing, water inlet 13 and delivery port 8 are opened on the Different Plane of following valve body, in the following valve body seal bar 5 is housed also, hinged by two connecting rods 4 between seal bar and the piston rod, seal bar is formed by two sections thread connection at the middle part, the connection place has clamped sealing mat 14, pressure cap 15 is housed above the last sealing mat, and thread connection between pressure cap and the following valve body is pressed on down last sealing mat on the port of valve body, spring 6 withstands between sealing mat and the pressure cap, lower seal pad 9 fixedly is equipped with in lower end in seal bar, in the bottom of following valve body, the side of water inlet has aperture 12, also has aperture 17 on the top of housing simultaneously, be connected with sebific duct 11 between two apertures, valve body is communicated with housing top.

When valve closing, lower seal pad 9 is positioned at top, water is entered by water inlet, enter into the upper space of housing by two apertures and sebific duct, because the pressure of water, piston moves downward, and compression spring 3 and connecting rod 4 force seal bar to drive the lower seal pad then and open port, water is flowed out from delivery port, the water on housing top is backflowed by aperture, is flowed out by delivery port, and this moment, the pressure owing to piston top reduced, spring 3 promotes piston and rises, drive seal bar and sealing mat simultaneously and rise,, so far finish a work period until valve closing.

Aperture by following valve body among the embodiment shown in Figure 2 two is opened in the side of water inlet 13, and sebific duct 11 is equipped with at the aperture place, and the bottom of housing has hole 20, and sebific duct 11 hole thus enters in the housing, and mouthpiece 21 is installed on the piston, and the sebific duct that enters in the housing is inserted on the mouthpiece.Reach the purpose that water inlet communicates with housing top aperture by this structure.A side relative with aperture at water inlet is equipped with tapered rod 22, it with following valve body between be threaded, sealing ring 23 is housed on tapered rod.When valve need be closed, the rotary conic bar utilized it to cut out aperture, and piston rod and seal bar stop action immediately, and supplying valve promptly quits work.

Claims

1, full-automatic intermittent formula supplying valve, it comprises the housing of upper end closed, it is characterized in that being equipped with the following valve body that has inlet and liquid outlet in the housing lower end, piston is housed in the housing, and under piston, spring is housed, in the following valve body seal bar is housed, be installed with on the seal bar, following two sealing mats, on last sealing mat, pressure cap is housed, the valve thread connection of pressure cap and following valve body is equipped with spring between pressure cap and the last sealing mat, passes through two rod hinge connections between seal bar upper end and the piston rod, following valve body bottom has aperture, and be equipped with conduit and communicate with housing top at the aperture place.

2,, it is characterized in that being equipped with by valve rod at the aperture place according to the said supplying valve of claim 1.
