Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water supply device for a local cleaning device which is installed in a water supply pipe line for tap water or the like (hereinafter referred to as a line) and does not use electricity (home AC power supply). In particular, by opening and closing the pilot orifice of the diaphragm valve with the pilot valve connected to the plunger by sliding the flow adjustment dial, the main valve seat can be opened and closed by interlocking the diaphragm valve, The present invention relates to a pilot valve type water supply device for a manual type local cleaning device that can vary the amount of cleaning water supplied to an anal cleaning nozzle or the like by turning a flow rate adjustment dial.

[0002]

2. Description of the Related Art Conventionally, a pilot valve type electromagnetic water supply valve (hereinafter referred to as a conventional valve) mounted on a local cleaning device or the like using electricity includes an inlet, an inflow pipe, an inflow chamber, and the like.
A soft diaphragm valve (valve element) is installed on a valve body in which a main valve seat, an outflow pipe, and an outlet are integrally formed with a synthetic resin molded member (for example, polypropylene resin) so as to close the main valve seat. A guide case (the inside is referred to as a back pressure chamber) of a synthetic resin molded member (for example, nylon resin) is pressed against the body so as to press the liquid-tight packing portion of the diaphragm valve. A plunger of a hard magnetic member (for example, a stainless steel rod) to which a soft pilot valve (valve element) of an elastic member (for example, silicone rubber) is fixed so that a pilot orifice of the diaphragm valve is closed, A coil spring (e.g., stainless steel wire) that is constantly urged is housed, and a copper wire (e.g., enameled wire) is provided on the outer periphery of the guide case with a cylindrical bobbin (e.g., a stainless steel wire). , Nylon resin), a solenoid (coil) connected to a terminal strip (for example, Faston terminal # 250) or a lead wire (electric wire) is installed, and a flow rate adjusting shaft having a wedge-shaped groove is installed in the outflow conduit. There is known a configuration in which a flow control dial is connected to the flow control shaft.

[0003] An inflow port is provided for connecting a tap water supply hose or the like. Inner circumference of the inflow pipe connected to the inflow port (the pressure of the inflowing water is referred to as a primary pressure or a high pressure side)
Has a function of preventing foreign matter (eg, insects, sand, iron scraps, etc.) from entering.
In many cases, a metal strainer (filter) having a mesh size or a flow rate adjusting component or a pressure reducing member is incorporated so that the flow rate is substantially constant irrespective of the primary pressure (dynamic pressure of the line).

[0004] Although there are exceptions, the predetermined flow rate is 10 L / min.
In the case of the flow rate control component in the case of less than, for example, as disclosed in JP-B-59-28796, JP-B-62-18787, etc., a synthetic resin molded member (for example, polyphenylene oxide resin, A hard cup of polyphenylene ether resin, polyacetal resin) and a soft annular disk of elastic member (for example, nitrile rubber) on the downstream side (hereinafter referred to as flocon, a conical inclined recess with a chamfered through hole in the approximate center) It is common to install a flow control component having a shape that is not molded.). When the primary pressure is supplied to the flow rate adjusting component at a low water pressure (for example, 0.05 to 0.10 MPa [megapascal] or less), the water pressure causes the hard cup to slightly press the floorcon. The flowing water passages provided in the hard cup (for example, a V-groove, a stepped groove, etc. in the case of a peripheral installation, a through-hole, etc. in the case of a substantially central portion) are secured as they are, Water less than the water flow rate passes. When the primary pressure is supplied at a medium water pressure (for example, about 0.10 to 0.50 MPa), the hard cup is more strongly pressed by the water pressure than at the time of low water pressure, and is provided on the hard cup. In addition, the flow control bites into the flowing water passage, so that the flowing water passage is narrowed, so that a predetermined amount of water or less is passed. Furthermore, the primary pressure is high water pressure (for example, 0.50 to 0.75M
(Pa or more), the hard cup almost bites into the floorcon due to the water pressure, and the flow passage is almost closed, so that a predetermined amount of water or less is passed.

[0005] Although there are exceptions, the predetermined flow rate is 10 L / min.
From about 35L per minute to about
For example, FIG. 6 and FIG.
And the like, the through-hole (also called an orifice, which is a flowing water pipe) substantially at the center of both end surfaces is bent by a change in water pressure or a flow rate of a fluid, and the cross-sectional area of the flowing water pipe changes. A flexible annular disk (hereinafter, referred to as a flow sheet) of an elastic member (for example, nitrile rubber) having a conical inclined concave shape formed so as to be easily formed, and a synthetic resin molded member (for example, polypropylene resin, It is common to install a flow control component composed of a hard color (a polyacetal resin) which is a support for a flow sheet for preventing fly-out at the time of backflow. With respect to the flow rate adjusting component, the flow sheet is bent and deformed due to a change in water pressure or a flow rate of the fluid, so that the flow pipe, which is the substantially central through-hole, is narrowed, and a predetermined amount of water or less flows therethrough. Will be.

The inflow chamber is a chamber surrounded by the inner wall of the valve body and the outer peripheral portion of the outflow pipe, and has a function of transmitting water pressure to the diaphragm valve. Usually, the cavitation generated in the inflow pipe is lost in the inflow chamber.

The main valve seat is shaped so that the diaphragm valve can easily bite in order to improve the water stopping performance.

[0008] A flow control shaft having a wedge-shaped groove is provided in the outflow pipe, and a flow control dial is connected to the flow control shaft. When the flow rate adjusting dial is rotated, the discharge amount of the wash water supplied to the anal washing nozzle or the like can be adjusted with an effective orifice determined by the intersection angle between the wedge-shaped groove of the flow rate adjusting shaft and the rectangular groove of the outlet. . The outlet is an outlet of the outflow conduit, and is a spout of washing water supplied to an anal washing nozzle or the like.

The diaphragm valve is provided, for example, with at least one small hole and one medium hole provided in a soft diaphragm made of an elastic member (for example, silicone rubber), and one surface of a hard disk made of a synthetic resin molded member (for example, polyacetal resin). (See, for example, registered utility model No. 3)
As disclosed in Japanese Patent Publication No. 010806 or the like, a plurality of small holes and small projections may be provided and fitted and connected. The small projection protrudes from the outer periphery of the diaphragm valve, and a side orifice (also referred to as a small hole or a bleed hole) penetrating the inflow chamber and the back pressure chamber (inside the guide case).
The central projection of the diaphragm valve has the central projection protruding therefrom, and is provided with the back pressure chamber and a pilot orifice (hole) passing through the back pressure chamber outlet. When installing the diaphragm valve on the valve body to close the main valve seat,
The side orifice is at the outlet of the inlet line. Because the cavitation generated in the inflow line is very rapidly compressed and disappears in the inflow chamber,
A sudden pressure rise (water hammer pressure) occurs, causing the diaphragm valve to float from the main valve seat, or the pressure difference (=
This is because it is presumed that the driving force is caused to flow from the side orifice into the back pressure chamber due to (water hammer pressure−back pressure chamber pressure).

When a current is applied to the solenoid (normally, a voltage of AC 100 V is applied to excite the solenoid), the plunger is attracted to a substantially central portion of the guide case provided inside the solenoid. The pilot valve closing the pilot orifice is released. Then, the water in the inflow chamber flows into the back pressure chamber from the side orifice,
The pilot orifice passes through the back pressure chamber outlet and exits to the outlet line and outlet. When this passage is opened, the diaphragm valve slightly floats from the main valve seat due to the decrease in the pressure of the water in the back pressure chamber and the pressure of the water in the inflow chamber. The water flowing into the back pressure chamber from the side orifice contracts once at the side orifice, so that the pressure is reduced and cavitation occurs. The water in the back pressure chamber has a rapid pressure rise (water hammer pressure) due to the disappearance of cavitation, and while constantly pressing the diaphragm valve floating from the main valve seat, the water in the outflow conduit, the flow It is estimated that it has flown to the exit. And since most of the water in the inflow chamber flows out to the main valve seat, the outflow pipe, and the outflow port,
The water at the hydrostatic pressure of the line falls to the hydrodynamic pressure and enters a flowing state. Due to the flow control components for flow control incorporated in the inlet, the water contracts once and the pressure drops, causing cavitation in the inflow pipe, disappearing in the inflow chamber, and causing a sharp pressure increase (water It is estimated that the diaphragm valve floats from the main valve seat.
Further, a pressure wave or the like generated due to a rapid pressure rise is not propagated to the line side (or the propagation amount is small) since the flow of water flows out from the inlet through the flow path of the outlet. ) Is assumed. Therefore, during the valve-opening operation of the conventional valve, the hydraulic pressure of the line (it decreases when the flow rate is large) is stable. As a reference, when the flow rate adjusting component is not installed, the pressure loss (= primary pressure−secondary pressure) of the conventional valve at the line hydraulic pressure is 0.01 MPa to 0.02 MPa, so that cavitation disappears. After that, it can be seen that the pressure almost recovers to the primary pressure.

Next, the flow of current to the solenoid is stopped (usually, a voltage of AC 100 V is cut off and demagnetized).
The plunger is returned to the normal position by the coil spring, and the pilot valve closes the pilot orifice. Then, the water flowing into the back pressure chamber from the side orifice loses its destination, but as described above, a sharp pressure rise (water hammer pressure) occurs in the back pressure chamber due to disappearance of cavitation. Therefore, the diaphragm valve floating from the main valve seat is pressed against the main valve seat. Then, the main valve seat is suddenly closed by the diaphragm valve to stop water, and the water in the inflow chamber cannot flow into the back pressure chamber from the side orifice, and the valve closing operation of the conventional valve is completed. I do.

[0012]

However, the conventional valve mounted on the local cleaning device or the like is naturally driven by electric (electromagnetic) operation. (Water supply and stoppage of water and adjustment of water discharge amount).

The present invention has been made in view of the above-mentioned problems of the prior art, and has as its object to operate an opening / closing valve by manual operation or the like (water supply, water stoppage, and water discharge amount adjustment).
