Description
Technical field
The present invention relates to the toilet technical field, in particular for the inlet regulating valve of water-saving toilet, can control the water yield that enters in the water tank.
Background technology
Water-saving toilet is comprised of ceramic bowl and flushing tank two parts.Tap water by certain pressure flows into the water tank compressed air to certain height, open control valve during bath, the water in the water tank promotes water and washes under compressed-air actuated effect, yet the inlet valve structure of existing water tank is complicated, easily break down, and cost is higher so that water tank when water inlet pressure a little less than, cause the compressed-air actuated pressure in the water tank relatively poor, thrust when washing by water is not enough, the insufficient pressure of water when causing washing, speed is less, causes flushing unclean.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiency in the prior art, be provided for the inlet regulating valve of water-saving toilet.
The technical solution adopted for the present invention to solve the technical problems is: a kind of inlet regulating valve for water-saving toilet, has valve body, one end of valve body is the water inlet of connecting water pipe, the other end of valve body is for connecting the delivery port of water tank, be provided with sliding spool in the valve body, be provided with the water inlet stage clip between valve body and the sliding spool, sliding spool axially has flow of inlet water near delivery port one end and regulates mouth.
Further, it is the little column structure in the large the inner of openend that described flow of inlet water is regulated mouth, and the radially bilateral symmetry of column structure is opened mouth, and port axially becomes sharp triangle and close sliding spool termination openings.Port is the sharp triangle curve hole of a pair of symmetry, and the radian of this curve can according to determining behind the experimental test, to guarantee the reaching purpose that the impulse force maximum is economized on water again most, reach water-saving purpose.When water closet discharges water flushing, the pressure of water is down to rapidly zero by the pressure of tap water in the water tank, in order to guarantee that water closet has larger flushing ability all the time, in the time of must guaranteeing each flushing in the water tank water rear water intaking valve of giving out light just can open into water, otherwise the air in the water tank is fewer and feweri, little air is during to certain stage, although the water in the water tank is many, but impulse force really descends greatly, even forms negative pressure in the flushing process, stops water outflow in the water tank.When discharging water flushing, the water inlet of water intaking valve and the pressure differential of delivery port strengthen suddenly by zero, rely on this large pressure differential to promote sliding spool rapidly to the right, close delivery port, open water intaking valve until the interior water of water tank approaches when discharging again, and intake in water tank.
Be provided with the relief valve device of not explosion of protection water tank on the described valve body near water outlet; relief valve device comprises the emergency valve seat that is fixed on the valve body, be arranged between safe spool, emergency valve seat and the safe spool in the emergency valve seat and be provided with safe spool stage clip; by cooperating of safe spool and safe spool stage clip, guarantee the unlikely explosion of water tank.
Described valve body internal spool valve core is fixed with the anti counter-flowing rubber seal near the end of water inlet, by anti counter-flowing rubber seal and sliding spool cooperate realization to cut off the water the time water tank in water can not flow backward to water supply pipe and pollute tap water.
The invention has the beneficial effects as follows: a kind of inlet regulating valve for water-saving toilet of the present invention, the flow that flows into by water in the regulating tank reaches good water-saving, and simple in structure, and regulation and control are convenient.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is structural representation of the present invention.
Among the figure 1, valve body, 11, water inlet, 12, delivery port, 2, sliding spool, 3, the water inlet stage clip, 4, flow of inlet water regulates mouthful, 51, emergency valve seat, 52, safe spool, 53, safe spool stage clip, 6, the anti counter-flowing rubber seal.
The specific embodiment
The present invention is further illustrated with preferred embodiment by reference to the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
The inlet regulating valve that is used for water-saving toilet as shown in Figure 1, has valve body 1, one end of valve body 1 is the water inlet 11 of connecting water pipe, the other end of valve body 1 is for connecting the delivery port 12 of water tank, be provided with sliding spool 2 in the valve body 1, be provided with water inlet stage clip 3 between valve body 1 and the sliding spool 2, sliding spool 2 axially has flow of inlet water near delivery port 12 1 ends and regulates mouth 4, it is the little column structure in the large the inner of openend that flow of inlet water is regulated mouth 4, the radially bilateral symmetry of column structure is opened mouth, and port axially becomes sharp triangle and close sliding spool 2 termination openings.Be provided with the relief valve device of protection water tank not explosion on the valve body 1 near delivery port 12 places, relief valve device comprises the emergency valve seat 51 that is fixed on the valve body 1, be arranged between safe spool 52, emergency valve seat 51 and the safe spool 52 in the emergency valve seat 51 and be provided with safe spool stage clip 53.Valve body 1 internal spool valve core 2 is fixed with anti counter-flowing rubber seal 6 near the end of water inlet.
After the flushing that discharges water begins, hydraulic pressure reduces in the water tank, and tap water is intake in the trend water tank by water intaking valve, and the pressure in the water tank and the pressure differential of tap water strengthen rapidly, last water tank is interior even form negative pressure, and the pressure differential of the pressure in the water tank and tap water will be greater than the pressure of tap water at this moment.If do not control the size of the water inlet that different phase intakes in the water tank, in the process of the flushing that then discharges water, external and internal pressure is poor increasing, and is also increasing through flow velocity, the flow of water intake valve, can not reach the purpose of fine water saving.Because flow of inlet water regulates the design of mouth 4 so that the flow of inlet water of different phase is different, has reached good using water wisely purpose.
Water flows backwards in the running water pipe and will pollute tap water in the water tank, so cooperate to prevent aqueous reflux in the water tank by anti counter-flowing rubber seal 6 and sliding spool.By cooperating of safe spool 52 and safe spool stage clip 53, when tap water pressure is too high, relief valve device will be opened release, guarantee the unlikely explosion of water tank.
Above-described embodiment only is explanation technical conceive of the present invention and characteristics; its purpose is to allow the personage that is familiar with technique can understand content of the present invention and is implemented; can not limit protection scope of the present invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
