Abstract

The utility model discloses a double-controlling sanitary flushing valve, which is composed of a valve body, a piston, an electromagnetic valve, a manual component, a drainage channel of an upper water chamber. The utility model is characterized in that the double-controlling sanitary flushing valve makes an internal chamber of the piston separated to be the upper water chamber and a lower water chamber through making use of the piston; through making use of pressure difference of the upper and the lower water chambers, and through a switch of the electromagnetic valve, opening and closing of the piston can be realized. An operating component of the switch of the double-controlling sanitary flushing valve is integrated of electric control and manual operation; the double-controlling sanitary flushing valve can not only be conducted with the electric control, but also can be conducted with the manual operation when power is shortage, and flushing effects and sealing performance of the double-controlling sanitary flushing valve are favorable.

Description

The double control-type plumbing flush valves

The utility model belongs to the plumbing field, relates in particular to the flushing valve of lavatory cleaning blowdown.

In lavatory blowdown irrigator valve apparatus, existing hand pulling type wc flushing cistern and the traditional delay-self-closing flushing valve of all using, its defective is: the former water supply volume is big, and component are fragile, causes out of control and leaks in a large number; Next is that volume is difficult for greatly installing.Latter's structure and complex process, the cost of production height.And its water shutoff performance is still poor, and by " the double control-type flushing valve " of inventor's invention, number of patent application 94247704.9 has solved the defective of said apparatus, but its structure is also imperfect, has increased material consumption, and lacks aesthetic appearance.

The purpose of this utility model is to improve 94247704.9 double control-type flushing valve structures, and a kind of good seal performance is provided, no drainage, and long service life, rational in infrastructure, aesthetic in appearance, and can be with the automatically controlled or manual double control-type plumbing flush valves of all realizing washing capacity.

The utility model is achieved in that the principle of utilization water generates pressure difference, it is relative with delivery port to make a water inlet with metal material, valve insertion is inclined between the entery and delivery port, the valve body of likeness in form " y " shape, and be the piston of one " worker " font two hydroeciums up and down with the valve insertion packing, establish a drain (as the upper tank sluice way) in the piston and go out the valve body delivery port, establish a miniature electromagnetic valve on the valve gap, be external to power supply and switch, by the keying of power switch control upper tank sluice way and the keying of piston, thus the function of realization electric-controlled switch.Still establish a push rod in the piston, its upper end withstands on the sealing-plug under the electromagnetic valve, and the lower end is pressed on the manual handle connecting rod of valve body, activity by manual handle, the keying of control electromagnetic valve and the keying of piston, and function is also opened in the realization manual control, has realized the purpose of this utility model.

Advantage of the present utility model: this device can be delayed time to wash and be closed automatically, and its water supply volume is few, and flushing ability is strong; Even good airproof performance also water-tight than hanging down under the hydraulic condition, has overcome the defective of traditional time-delay flushing valve water shutoff difference.And the control of this flushing valve current collection with manual in one, realized the electrification of lavatory flushing, can under no electric condition, manual operations also realize its function again.

The explanation of accompanying drawing drawing: accompanying drawing is this device sectional drawing.

On scalene valve body, water inlet (1) is arranged on the relative position with delivery port (2), valve insertion is established an aperture at interior side valve wall and is fed water inlet (1) as upper tank inlet opening (3) tiltedly between water inlet (1) and the delivery port (2).Sealing mat (5) is loaded onto at " worker " font piston (4) two, and piston (4) center is the hollow sluice way (6) of upper tank (9) that is, piston (4) lower end is adorned one and fallen the steady lifting of " mountain " shape location key seat (7) with support piston (4); Its upper end is provided with sealing column (8) shutoff sluice way (6), piston (4) is two hydroeciums (9) (10) up and down with the valve insertion packing, valve gap (11) is gone up the lifting of dress electromagnetic valve (12) control sealing column (8), promptly control the keying of sluice way (6), external power supply and the switch gone up of electromagnetic valve (14), still be provided with manual push rod (13) in the sluice way (6) in the piston (4), push rod (13) upper end withstands under the sealing column (8), and the lower end withstands on the handle and connecting rod (14).

The course of work: under the normal condition, closed electromagnetic valve, be that sluice way (6) in the piston (4) is closed, when water advances lower header (10) from water inlet (1), also enter upper tank (9), at this moment from upper tank inlet opening (3), the pressure of upper tank (9) is greater than the pressure of lower header (10), piston (4) is down pushed away, and seals delivery port (2), and water is promptly dammed.When connecting power of electromagnetic valve, sealing column (8) is picked up, open at upper tank sluicing road junction (6), the water of upper tank (9) is discharged from sluice way (6) toward delivery port (2), the pressure of upper tank this moment (9) is less than lower header (10), piston (4) up promotes, and delivery port (2) is opened, and water promptly rushes at bedpan from delivery port (2).Behind the powered-down, electromagnetic valve sealing column (8) is closed, is that sluice way (6) is closed, after water is discharged certain hour from delivery port (2), upper tank (9) progressively is full of water, its pressure constantly increases, and when its pressure during greater than the pressure of lower header (10), piston (4) is pushed downwards again, envelope stops flushing toward delivery port (2).Under power failure short of electricity situation, when needing flushing, connect lower handle, connecting rod (14) is lifted push rod (13) top, and electromagnetic valve sealing column (8) is opened, and promptly enters working programme same as described above.

Claims (2)

1, the double control-type plumbing flush valves is made of valve body, valve gap, piston, location key seat, push rod, handle and electromagnetic valve, it is characterized in that the water inlet on the valve body is relative with delivery port, and valve insertion is inclined between the entery and delivery port; The piston lower end is provided with location key seat and shutoff delivery port, and the piston upper end is provided with the electromagnetic valve sealing column, and electromagnetic valve is located on the valve gap; Water outlet valve wall place is provided with handle and connecting rod, and connecting rod is provided with push rod and withstands under the electromagnetic valve sealing column.

2, flushing valve according to claim 1 is characterized in that piston is " worker " font, and it is upper tank and lower header with valve pocket every envelope, and the piston center is provided with the upper tank sluice way, and interior side valve wall is provided with the upper tank inlet opening.
