Abstract

The utility model provides a filter screen cleaning valve, which comprises a valve body and a shifting lever; the valve body is provided with a cavity, and a water inlet, a water outlet and a sewage outlet communicated with the cavity are formed on the valve body; the shifting lever can be rotationally and hermetically arranged in the valve body; two phases of communicated limber openings are formed on the shifting lever; a filter screen is stably combined with one of the limber openings on the shifting lever through a gland bush; the limber opening, at which the filter screen is arranged, is correspondingly communicated with the water inlet of the valve body during normal filtration, so as to filter impurities in water; if the filter screen needs to be cleaned, the shifting lever is rotated to enable the shifting lever to be corresponding to the sewage outlet of the valve body; the filter screen is flushed back by utilizing water at the water inlet; and the filter screen can be easily and quickly cleaned without dismounting the filter screen.

Description

The filter screen cleaning valve

Technical field

The utility model relates to the field of water heating fittings valve, specifically is meant a kind of filter screen cleaning valve.

Background technique

Flow through in the external water source transmission course behind pipeline and the valve body; regular meeting is mingled with various silts in the water; metallic oxide or the like impurity; as filtered directly connect watering equipment as the gondola water faucet of sanitaryware; shower nozzle etc.; because gondola water faucet; the water route is many and thin in the shower nozzle; impurity in the water stops up the water route easily; make gondola water faucet; the shower nozzle water outlet does not freely influence using effect; and the working life of shortening product; therefore common externally water source connects water route one end that enters sanitaryware one filtrating equipment is set; to stop the impurity in the filtered water; in the use; after the filter screen impurity of this filtrating equipment gathers; must clean to guarantee that current are unobstructed filter screen; traditional cleaning process is filtrating equipment to be taken apart filter screen taken off to install after the cleaning again go back; and need before the dismounting earlier the water route to be closed, whole process operation is many and operation is extremely inconvenient, wastes time and energy.

The model utility content

For this reason, the purpose of this utility model is to provide a kind of filter screen cleaning valve, and need not dismounting can clean filter screen, simple to operate, easy to use.

For achieving the above object, the technical solution of the utility model is:

A kind of filter screen cleaning valve, form by valve body and changer lever, described valve body tool chamber, and form the water intake, water outlet and the sewage draining exit that connect chamber, the rotating sealing of described changer lever is located in the valve body, changer lever is provided with two inletes that are connected, and a filter screen firmly is incorporated into a wherein inlet of this changer lever by gland, and makes alternative corresponding water intake or the sewage draining exit that is communicated with valve body of this inlet.

One end face of this changer lever outwards extends a location annular groove, and this positioning ring groove makes changer lever firmly be arranged in valve body in conjunction with a collar.

Then be provided with adjusting portion on the other end of this changer lever and stretch out and protrude a limited part.

One end face of this valve body is provided with limited step.

The utility model adopts said structure, change the sewage draining exit that makes the corresponding connection of the inlet valve body that is provided with filter screen by rotating changer lever when cleaning filter screen, utilize the water back flush filter screen of water intake, can finish the cleaning of filter screen easily, efficiently, and operate very simple, whole process need not dismounting, has improved to commonly use filter screen and need from the many and unhandy problem of reinstalling again after member is pulled down cleaning of operation.

Fig. 2 shows filter screen normal filtration state for the utility model combination schematic representation;

Fig. 3 shows the state that filter screen cleans for the utility model combination schematic representation.

Embodiment

As shown in Figure 1, be filter screen cleaning valve of the present utility model, can use on the inlet pipeline that is installed on a kind of watering equipment (sanitaryware), by valve body 1 and changer lever 2 form, changer lever 2 rotating sealings are located in the valve body 1, described valve body 1 tool chamber 11, and form the water intake 12, water outlet 13 and the sewage draining exit 14 that connect chamber 11, and an end face of valve body 1 is provided with limited step 15, the water intake 12 corresponding water pipes that are communicated with of this

valve body

1,13 corresponding connection watering equipments of water outlet, and sewage draining exit 14 is used for effluent impurity;

Described changer lever 2 is provided with two inletes that are connected 21,22, one filter screen 23 firmly is incorporated into the inlet 21 of changer lever 2 by gland 24, and a wherein end of these changer lever 2 both ends of the surface outwards extends a location annular groove 25, the other end then is provided with adjusting portion 26 (can be made as the cross recess structure), and this end face stretches out and protrudes a limited part 27; During assembling in 2 combination seal spares, 3 sealings of this changer lever and the rotating chamber 11 of being located at valve body 1, and the positioning ring groove 25 of changer lever 2 one ends makes changer lever 2 firmly be arranged in valve body 1 in conjunction with a collar 4, be positioned at the limited step 15 of valve body 1 with the limited part 27 of seasonal changer lever 2, to limit direction and the angle that changer lever 2 rotates relative to valve body 1;

After the filter screen cleaning valve of the present utility model installation, the normal filtration state as shown in Figure 2, the inlet 21 corresponding sealings that make changer lever 2 be provided with filter screen 23 are communicated with the water intake 12 of

valve body

1,22 corresponding sealings of changer lever 2 another inletes are communicated with the water outlet 13 of valve body 1, the sewage draining exit 14 of valve body 1 then is a not on-state, the limited part 27 of changer lever 2 is resisted against first end 151 of valve body limited step 15 at this moment, water is entered after filter screen 23 filters by water intake 12 and is communicated to watering equipment by water outlet 13 outflows, and filter screen 23 filters the impurity that stays and then accumulates in the A place shown in Fig. 2; When needs clean filter screen 23, as shown in Figure 3, adjusting portion 26 on the operation changer lever 2, make changer lever 2 rotations make limited part 27 be resisted against second end 152 of valve body limited step 15, make the inlet 21 corresponding sewage draining exits 14 that are communicated with valve body 1 that are equiped with filter screen 23 this moment after changer lever 2 rotations, the then corresponding water intake 12 that is communicated with valve body 1 of another inlet 22 of changer lever 2, this moment, the water outlet 13 of valve body 1 was a not on-state, water enters back flush filter screen 23 by the water intake 12 of valve body 1, the impurity that accumulates in filter screen A place is discharged by the sewage draining exit 14 of valve body 1, after finishing cleaning, the adjusting portion 26 of operating changer lever 2 again makes changer lever 2 counterrotatings return back to normal drainage state.

The utility model adopts said structure, can finish the cleaning of filter screen easily, efficiently, and operation is very simple, and whole process need not dismounting, so the further expansion of the utility model also can be applicable in the delivery line of various fluids, and application area is wider.
