Description

Time delay shut-off valve for toilet

The utility model relates to a kind of sanitary flush valve, especially for the washroom, and lavation chamber, the plumbing flush valves of the energy automatic delay function of occasions such as lavatory.

Used the washroom, the sanitary flush equipment of occasions such as lavatory mostly is high and low water tank greatly in the past.Promptly waste water, wayward again.For addressing the above problem, a kind of scheme has been proposed in the Chinese patent application 86200387.Replace the high-level or low-level water case with plumbing flush valves.But this flushing valve must be used with antifouling helping towards device, have control dumb, the volume of whole valve is bigger.The shortcoming of flushing pressure deficiency.

Task of the present utility model is to propose a plumbing flush valves that has improved.Closing of energy automatic delayed by-pass valve control can increase the speed of flushing pressure again.

Task of the present utility model is reach like this valve body is connected on the water supply pipe, (pressure of tap water should greater than 1 kg/cm).Tap water enters control chamber from bleed off pipe.Press the button, depress the elastic membrane pad, cleansing pin pressurized simultaneously moves down, and the compression spring.Water in the control chamber is expelled to delivery port by the water-guiding hole that control valve puts through aqueduct at this moment.After this part water was discharged, the ponding in the control valve pocket reduced, and with the pressure disequilibrium of tap water, under the effect of tap water pressure, will control guiding valve jack-up.Water flow to from valve seat and penetrates the increase of suction inlet pressure, and flow velocity is accelerated, and flows out flushing from outlet, and another part water enters the control chamber of controlling valve pocket through spout hole.At this moment, move down under the effect of the water that the control guiding valve reenters in this section and the restoring force of spring, until valve closing.Be the time of time-delay during this period of time,, can reach the adjustable purpose of water outlet time delays by changing the diameter of spout hole.

The advantage of plumbing flush valves of the present utility model is that flushing pressure and speed are big.Washing time is adjustable, using water wisely.The similar plumbing flush valves of the volume ratio of whole flushing valve is little.Low cost of manufacture, material source is extensive, and cast iron, lead, steel, copper or plastic or other material all can.Range of application is more extensive simultaneously, the washroom, and the lavatory, the occasion that lavation chamber etc. need be washed away all can be used.

Description of drawings, accompanying drawing are the structure sectional views of a specific embodiment of utility model.Plumbing flush valves in the accompanying drawings mainly contains valve body (1), outlet pipe (2), aqueduct (3), knob (4), knob gland (5), elastic membrane pad (6), joint ring (7), control valve pocket (8), joint ring (9) cleansing pin (10), spring (11), rubber ring (12), y-type seal ring (13), control guiding valve (14), valve seat (15), seal (16), water inlet plug (17), air vent (18), joint (19), (20).Penetrate and inhale hole (21), spout hole (22), water-guiding hole (23) is formed.

Below in conjunction with accompanying drawing the specific embodiment of plumbing flush valves of the present utility model is given to describe in detail.

With reference to accompanying drawing, control valve pocket (8) is equipped with on the top of valve body (1), and water outlet one side is equipped with outlet pipe (2), and control valve pocket (8) is linked by joint (19), (20) and aqueduct (3) and outlet pipe (2).Control ponding in the inner chamber of control valve pocket (8) flows into outlet pipe (2) by aqueduct (3).In valve body (1), also be fixed with a valve seat (15).Valve seat (15) can be with the independent processing and fabricating of materials such as copper or antimonial lead.Control guiding valve (14) has been adorned in the control valve pocket (8).On the control guiding valve (14) y-type seal ring (13) is housed, Y type opening is towards the direction of button (4), and the lip limit of y-type seal ring forms sealing surface with the inwall of control valve pocket.Go up semi-enclosed hole of matching in addition at control guiding valve (14) with spring (11), the other end of control guiding valve (14) is equipped with into water stopple (17), is equipped with the hermetic unit that seal (16) and valve seat (15) form plumbing flush valves on-off water of the present utility model between water inlet stopple (17) and control guiding valve (14).There is the sliding groove in 4～6 gardens in the outer garden of control guiding valve (14) on week, to reduce the resistance that slides up and down when control guiding valve (14) is worked, increase the sensitivity of its control.The bottom cleansing pin of cleansing pin (10) from the spout hole of semi-enclosed hole of control guiding valve (14) and water inlet stopple (17) by (prevent spout hole obstruction).The diameter of spout hole (22) is 0.3～1 times of cleansing pin diameter.The top of cleansing pin (10) is the cleansing pin bar that is with sealing ring (12), and the cleansing pin bar passes from the upper guide water hole (23) of control valve pocket (8), and sealing is therebetween realized under spring (11) and pressure by sealing ring (12).Plumbing flush valves of the present utility model is connected on the water supply pipe (pressure of tap water should greater than 1 Kilogram Force Per Square Centimeter).Tap water enters the inner chamber of controlling valve pocket (8) through spout hole (22), will control guiding valve (14) jack-up simultaneously, and the compression spring has part of running water to flow out to outlet pipe (2) from valve seat (15).By the time when controlling the pressure balance of interior water pressure of valve pocket (8) and tap water, under the restoring force effect of spring (11), plumbing flush valves of the present utility model is closed.Press the button (4), elastic membrane pad (6) moves down thereupon, the cleansing pin bar of cleansing pin (10) is depressed, also compressed simultaneously spring, make water-guiding hole (23) locate to form a space, ponding in the control valve pocket (8) is under the pressure effect of itself, and the gap flow to aqueduct (3) and enters outlet pipe (2) thus, loosens the space of button (4) water-guiding hole (23) and promptly closes.Since after ponding flows out, control valve pocket (8) inner chamber and ducted tap water pressure imbalance, and tap water will be controlled guiding valve (14) jack-up.Tap water is inhaled hole (21) supercharging after-acceleration outflow along valve seat (15) through penetrating.Another part tap water enters into the inner chamber of controlling valve pocket (8) from spout hole (22), and under the restoring force effect of spring, flushing valve is closed in pressure balance.Finish the once flushing process.The effect of joint ring (7) is to prevent that the water that flows out from water-guiding hole (23) from leaking to the outside of button (4).Button (4), elastic membrane pad (6) button gland (5) is formed the control section that flushes out the water yield.That is: press the button then water outlet, loosen a period of time of to delay time behind the button and just can stop water outlet.It is hole, a tapered cross-section that penetrating in the outlet pipe (2) inhaled hole (21).Tap water through valve body (1) and valve seat (15) outflow quickens in this place's supercharging.Pressure and speed that the tapering of change taper hole can be regulated water outlet, tapering can change arbitrarily in 0～90 ° of scope, to satisfy the water requirement of all kinds of different service conditions.The effect of air vent (18) is to prevent that producing negative pressuren zone at a position influences developing result.The quantity of air vent is 1～6.

The time-delay process of plumbing flush valves of the present utility model is that the water yield adjusting is to rely on the diameter that changes spring (11) and spout hole (22) to realize.The coefficient of rigidity of spring is big, and the process time of then delaying time is short, water yield is few.The coefficient of rigidity of spring is little, and the diameter of spout hole is also little, and the process time of then delaying time is long, and water yield is big.In general the use, usually the coefficient of rigidity of spring is fixed, the spring of promptly choosing has just no longer been changed, and the diameter that only changes spout hole reaches the purpose that control time-delay process time promptly changes water yield.This method is relatively simple.
