Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a flow control device and a water saving cylinder for saving water of a flush valve used for supplying water to a flush toilet and the like.

[0002]

[Prior art]

 Conventionally, flush valves used for flush toilets and the like usually have an adjusting device attached to the valve itself, and an adjusting valve is usually used for a water supply pipe thereof.

[0003]

[Issues to be solved by the invention]

 By adjusting the adjustment valve and flush valve currently used, the flow rate per operation can be adjusted to the minimum necessary (for example, 8 liters), but the actual piping work is completed before water supply. In addition to the fact that there is virtually no regulation of water supply conditions, the pressure of tap water varies from place to place. For example, the same flush valve may be determined due to the distance between the installation location of the flush valve and the water supply main pipe, the difference between the base end and the front end in the same water pipe, or the height of the installation location (for example, the first and tenth floors of a building). It was almost impossible to adjust each flush valve or the attached control valve to obtain the proper amount of water from each valve, because of the problem that the water volume coming out of the valve varied greatly.

[0004]

[Means for Solving the Problems]

 However, according to the present invention, a water-saving cylinder is interposed in a connecting pipe connecting the adjusting valve and the flush valve so that the amount of flowing water can be adjusted according to the water pressure, so that the above problem can be solved.

[0005] That is, the invention of the flow control device is a flow control device characterized in that a water-saving cylinder is interposed in a connecting pipe connecting the adjustment valve and the flush valve. In addition, the invention of a water-saving cylinder is based on the idea that, in a water-saving cylinder interposed in a connecting pipe connecting a regulating valve and a flush valve, the inner diameter of the inlet side of the cylindrical body is made larger than the inner diameter of the outlet side, and the above-mentioned inlet side is A water-saving cylinder characterized in that a hook flange is provided on the outer periphery of the mouth. Another water-conserving cylinder was devised in a water-conserving cylinder interposed in the connecting pipe that connects the regulating valve and the flush valve, in which the inside diameter of the inlet side of the cylindrical body was made larger than the inside diameter of the outlet side, and A water saving cylinder characterized in that the joint between the inner wall on the inflow side and the inner wall on the outflow side of the cylindrical body is inclined in the outflow direction, and is provided through a connecting pipe connecting the adjustment valve and the flush valve. In the water-saving cylinder to be mounted, the inner diameter of the inflow-side opening of the cylindrical body is made larger than the inner diameter of the outflow-side opening, and the inner peripheral edge of the inflow-side opening and the inner peripheral edge of the outflow-side opening are chamfered. It is a water saving cylinder that is a feature.

[0006] The inner diameter of the outlet side of the water-saving cylinder is determined by the amount of water discharged to a flush toilet or the like and the water pressure of the tap water. In other words, once the amount of water discharged to a flush toilet (for example, 8 liters) is determined, the amount of water is kept constant for the same flush valve. By measuring the water supply pressure of the water supply, the water-saving cylinder with the required inner diameter can be immediately determined.

[0007]

[Embodiment of the invention]

 According to this invention, the drainage is controlled by interposing a water-saving cylinder in the connecting pipe connecting the regulating valve and the flush valve. In the water-saving cylinder, a hook flange is provided on the outer periphery of the inflow-side opening of the cylindrical body, and the inner diameter of the inflow-side opening is increased and the inner diameter of the outflow-side opening is reduced.

[0008]

Embodiment 1 An embodiment of the present invention will be described with reference to FIG.

An annular flange 3 is formed on two outer circumferences of the inflow side port of the cylindrical body 1. It is larger than the inner diameter D ₂ of the outlet-side opening portion the inner diameter D ₁ of the inlet-side mouth 2 of the cylinder 1. A water-saving cylinder 8 is formed by forming an inclined surface 7 at an abutment between the inner wall 5 of the inflow side port 2 and the inner wall 6 of the outflow side port 4 in the outflow direction and at 45 degrees to the center line. ing. The reason why the inclined surface 7 is set to 45 degrees is that when water flows in from the inflow side port 2 as shown by arrow 9, the water smoothly passes through the incline 7 and the outflow side port 4 of the inner diameter D _2. It can be flowed inside. In FIG. 1B, reference numerals 10 and 11 denote inclined surfaces formed on the inner peripheral edge of the inflow side port portion 2 and the inner peripheral edge of the outflow side port portion 4. Although the shape of the water-saving cylinder 8 is the cylindrical body 1, it is not limited to the above-mentioned shape. In addition, since the annular collar 3 is for stably locking the water saving cylinder, the shape is not limited as long as the purpose is achieved.

[0010]

Embodiment 2 An embodiment of the device of the present invention will be described with reference to FIG. In this embodiment, a water saving cylinder 8 of the above embodiment is interposed in a connecting pipe 14 between an adjustment valve 12 and a flash valve 13. The adjusting valve 12 is provided in a valve housing 17 having an inflow port 15 from below and an outflow port 16 connected to the connection pipe 14, and a valve seat 18 provided inside the inflow port 15. The valve body 19 is installed so as to be able to move up and down, and the valve rod 20 of the valve body 19 is inserted and held in the shaft hole 22 of the adjusting rod 21 screwed to the upper wall of the valve housing 17. I have.

The flash valve 13 is provided with a piston valve 26 which can be moved up and down in a valve housing 25 having an inlet 23 connected to the connecting pipe 14 and an outlet 24 opening downward. It is configured.

An upper part of the piston valve 26 is inserted into a water chamber 27 provided in a cylindrical shape inside the valve housing 25, and a lower part of the piston valve 26 is an annular valve provided on an upper part of the outlet 23. It has an annular flange 29 that comes into contact with the seat 28 and is fitted into the outlet 23 so as to be liftable. A water passage 31 having a valve seat 30 is formed inside the upper end of the piston valve 26, and a valve rod 33 of a valve body 32 abutting on the valve seat 30 hangs downward from the water passage 31. , The valve body 32 and the valve rod 33 constitute a starting valve 34. A handle 27 for operating an activation valve 34 is slidably mounted on a side of the valve housing 25, and a tip of the handle 27 is opposed to the valve rod 33, and the valve rod 33 and the handle 27 are A spring 35 that constantly urges the handle 27 away is mounted, and the position of the handle 27 is stably held by the spring 35 and the flange 36 of the handle 27. A groove 37 is provided in the lower peripheral wall of the piston valve 26 to form a flowing water gap.

In the above embodiment, when the pressurized water reaches the inflow port 15 as indicated by an arrow 38, the pressurized water pushes up the valve body 19 in the same direction, passes between the valve body 19 and the valve seat 18, It passes through the outlet 16 as shown by the arrow 39 and reaches the inlet 23 of the valve casing 25 via the connecting pipe 14 (that is, the inlet 23 is filled with pressurized water). Then, when the handle 27 is protruded in the direction of the arrow 40, the tip of the handle 27 presses the valve rod 33 of the starting valve 34 in the same direction, so that the valve rod 33 is inclined as indicated by a chain line 41. Then, the valve element 32 is also inclined, and the water in the water chamber 27 flows down through the water inlet 31. Therefore, the pressure difference between the inlet port 15 and the inside of the water chamber 27 causes the piston valve 26 to move in the direction indicated by the arrow. It rises like 42. When the piston valve 26 rises, the upper part of the groove 37 provided below communicates with the inlet part 15, and the pressurized water flows down as indicated by the arrow 43. On the other hand, a small hole 44 is vertically formed in the upper piston portion of the piston valve 26, and the small hole 44 communicates the water chamber 27 with the inflow portion 15, so that the piston valve 26 rises. At the same time, pressurized water flows into the water chamber 27 from the small holes 44. As the pressurized water enters the water chamber 27, the piston valve 26 descends, and the water chamber 27 is filled with the pressurized water. At the same time, the piston valve 26 seals the outflow port 24, thus completing one discharge. (Each part returns to the state before water discharge).

[Effect of the invention]

 According to this invention, since the water-saving valve is interposed in the connecting pipe connecting the adjusting valve and the flush valve, there is an effect that the amount of water discharged into the flush toilet once can be adjusted regardless of the water pressure. In addition, in this invention, since the flow rate is regulated by making the inner diameter of the outlet side smaller than the inner diameter of the inlet part of the cylindrical body, there is no movable part in the flowing water, and vibration occurs due to water control and noise is generated. There is no danger of this occurring, and there is an effect that the water flow can be accurately controlled. Further, there is an effect that the control operation is simple and the accuracy is high.
