Abstract
The utility model relates to a self-closing flushing valve which adopts an L-shaped sealing ring on the structure of a piston and takes a guide claw on a piston body and the external side of an upper press cap as a guide part of a piston motion. Moreover, an exhaust vent is directly arranged on a valve body, and a starting mechanism is designed into a push rod type. Therefore, the utility model is made into a self-closing flushing valve which has the advantages of compact and reasonable structure, good sealing performance, long service life and no water hammer phenomenon. The valve has small size and saves water over 50% more than that of a water tank of an ordinary urinal. The valve which is ideal flushing equipment of a toilet urinal for a hotel, a restaurant, a hospital, a factory and mine and a dwelling can also be widely used in an industrial department as a quantitative fluid delivering valve.
Description
The utility model belongs to self-closing flushing valve, mainly as the various flushing devices of pedaling sitting urinal in public lavatory or washroom of hotel, restaurant, hospital, factories and miness and residential houses, town and country, also can be used as quantitative fluid-delivery valve and uses.
Known self-closing flushing valve is made of valve body, bonnet, piston, attaching nut, connection sealing ring, handle wrench dynamic formula actuating mechanism, the air cut off device etc. that is provided with steam vent, wherein piston is assembled by piston body, upper press cover, sealing ring, lower cover, sealing mat, spool, valve core spring, screen pack, and has throttle orifice on the piston body.This self-closing flushing valve, physical dimension is big, and is fast as the ring wear of one of piston component in the use, and application life is short, has water hammer when piston is closed, and causes the vibration of supply channel, and in addition, during flushing, steam vent leaks.
It is reasonable that the purpose of this utility model provides a kind of compact conformation, good seal performance, and long service life , And can overcome the self-closing flushing valve of water hammer.
This self-closing flushing valve is made of valve body, bonnet, piston, attaching nut, connection sealing ring, actuating mechanism and steam vent.The position of piston in valve body designed according to the water inlet direction, and when vertical direction was intake, piston can be tilting, and when horizontal direction was intake, piston can vertically be provided with.Piston is assembled by piston body, upper press cover, sealing ring, screen pack, lower cover, sealing mat, spool, valve core spring, and wherein piston body has radially throttle orifice and spool bore, and spool, valve core spring and seal spool pad are contained in the spool bore.The guiding of piston partly is made up of four guide grabs of piston body bottom and the lateral surface of upper press cover, is pressed in sealing ring employing L RunddichtringO on the piston body by upper press cover.This piston structure, the water hammer in the time of can overcoming piston and close, in addition, the L RunddichtringO has tension force, good seal performance, long service life.
Actuating mechanism is a transfer bar mechanism, and its position can just be put, also can side, and it is made of push rod, push-rod hole, spring, clamp nut and seal, and this push-down actuating mechanism is easy to operate, reliable, and physical dimension is littler than handle wrench dynamic formula actuating mechanism.
Steam vent be directly open on the valve body outwards above tilting tilting hole, the effect in this hole is the foul smell of discharging urinal, makes its not polluted source, water did not spill along drain hole when the tilting direction in this hole can guarantee to wash.
This manual has the following drawings:
Fig. 1: A-A sectional view of the present utility model;
Fig. 2: top view of the present utility model;
Fig. 3: the upward view of piston body.
Diagram:
1. valve body; 2. bonnet; 3. piston body; 4. screen pack; 5. throttle orifice; 6.L RunddichtringO; 7. upper press cover; 8. lower cover; 9. spool; 1.0. valve core spring; 1.1. push rod; 1.2. push-rod hole; 1.3. spring; 1.4. clamp nut; 1.5. steam vent; 1.6. attaching nut; 1.7. connection sealing ring; 1.8. inlet opening; 1.9. weep hole; 2.0. valve pocket; 2.1,2.2,2.3, the 2.4. sealing mat; 2.5. packing ring; 2.6. guide grab; 2.7.O RunddichtringO.
Accompanying drawing has been described a kind of embodiment of the present utility model.
Inlet opening (18), weep hole (19), valve pocket (20), push-rod hole (12) and steam vent (15) are arranged on the valve body (1), inlet opening (18) side, the horizontal direction water inlet, button hole (12) horizontal direction is just put, and steam vent (15) outwards top is tilting.Piston is installed in the valve pocket (20), assemble by piston body (3), upper press cover (7), L RunddichtringO (6), copper wire screen pack (4), lower cover (8), sealing mat (22,23), spool (9), valve core spring (10), wherein spool (9), valve core spring (10) and sealing mat (22) are contained in the spool bore of piston body (3), also has radially throttle orifice (5) on the piston body (3), link up valve pocket (20) and spool bore, copper wire screen pack (4) is then to the water filtration of the throttle orifice of flowing through (5).Four guide grabs (26) are arranged at the bottom of piston body (3), and the lateral surface of guide grab (26) and upper press cover (7) forms the guiding part of piston motion jointly.Push rod (11), spring (13), sealing mat (24), O RunddichtringO (27) and packing ring are housed in the push-rod hole (12), and (25) , And compress with clamp nut (14).The top of valve body (1) has sealing mat (21) and bonnet (2) to bind.Weep hole (19) is located to be equipped with attaching nut (16) and is connected sealing ring (17), relies on the distortion that connects sealing ring (17) to hold the cleaning hose that same valve body (1) connects tightly.
In order to deepen that understanding of the present utility model is necessary to narrate the course of work of this flushing valve:
Hand is pushed push rod (11), pushes spool (9) open, and the water of uuper valve chamber flows out through spool bore, and piston is up under the pressure differential effect of water, opens valve opening and discharges water.After hand was thrown off push rod (11), spool (9) was closed, at this moment, the water that flows to uuper valve chamber through filter screen (4), throttle orifice (5), spool bore is full of uuper valve chamber gradually, increased pressure, and And is under the pressure differential effect, promote descent of piston, last self-closing valve hole stops to discharge water.Discharge time generally is designed to 15 seconds, so this valve can be used as quantitative fluid-delivery valve and use, and when using as the urinal flushing valve, controls and pushes the push rod time and can do the adjusting of certain limit to discharge time, reaches water-saving purpose.
In sum, the utility model has overcome the existing problem of known self-closing flushing valve, that a kind of compact conformation is reasonable, good seal performance, long service life does not have the self-closing flushing valve of water hammer, this valve body is long-pending little, more than 50%, be the desirable flushing device of modernized urinal than Water tank for urinal using water wisely, also can be used as the quantitative transfusion valve and be used widely at industrial department.
