Abstract

PROBLEM TO BE SOLVED: To provide a device for adjusting the difference between the pressures imposed on both liquid valves, which can be used for supplying any liquids different in pressure and controlled accurately at an optionally mixed rate. SOLUTION: This device is constituted of valve main bodies, a pressure adjusting unit, two meshed members, and a liquid introducing part. The pressure adjusting unit is arranged at the position where both liquids meet so as to interlock with each other by the valve bars so that the impact, which is received on one of the members by introducing the liquid to be made to flow in through any of the liquid inlets, is transmitted to the other of the members to be rotated.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has two liquid water supply valves, and when both liquids are supplied with unequal water pressure,
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a differential pressure adjusting device for two liquid valves, which can prevent a liquid having a relatively small water pressure from being blocked by adjusting a differential pressure by a pressure adjusting device.

[0002]

2. Description of the Related Art Conventionally, this type is as follows. Cold used in everyday life,
The hot water faucets are provided with cold and hot water launching pipes, respectively, and the water temperature must be adjusted according to the demand for use, so that the amounts of cold and hot water launched and the water pressure also differ.

[0003] The following problems can be pointed out for such conventional cold and hot water faucets. In the conventional cold and hot water faucet described above, the amount of cold and hot water launched and the water pressure are different. Therefore, when two liquids with different water pressures meet, the relatively lower liquid (usually hot water) will have a resistance. Receiving makes it harder to drain. Therefore, by discharging a relatively large amount of the liquid having a relatively low water pressure, the liquid having a relatively low water pressure can be smoothly discharged, and then the amount of the liquid must be gradually reduced. In the process of this adjustment, firstly, water is wasted, and if the pressure difference between them is too large, the liquid having a relatively low water pressure cannot flow out. When the device cannot be ignited, a problem arises that gas continues to leak.

SUMMARY OF THE INVENTION The present invention has been made in view of such problems of the prior art,
An object of the present invention is to provide a differential pressure adjusting device for both liquid valves that can achieve the following. SUMMARY OF THE INVENTION It is an object of the present invention to provide a differential pressure adjusting device for a liquid valve which can be used for supplying liquids having different hydraulic pressures and can accurately control mixing arbitrarily.

[0005]

In order to achieve the above object, a differential pressure adjusting device for a liquid valve according to the present invention is as follows. That is, the differential pressure adjusting device for the two liquid valves according to the present invention includes a valve body, a pressure adjusting device, two meshing members, and a guiding portion. The valve body is provided with two water intakes and one water outlet, and a control valve is provided at each of the inlets of the two water intakes. Can be controlled. Since the pressure regulating device is provided in the valve body at a place where the two liquids meet, any liquid having a different hydraulic pressure can be supplied. The two meshing members are housed in the pressure regulating device, and the two meshing members are rotatably formed by meshing with each other by being fitted by the shaft of the valve body. By receiving the strike introduced by the liquid flowing in from the water intake,
The rotation of the other meshing member can be transmitted.
The guiding portion is located at the two water intakes and is formed so as to substantially surround the pressure regulating device. Since both ends of the guiding portion are formed in an arc, the inflows from the two water intakes. Cold,
Hot water can be directed to enter the pressure regulator.

Further, the differential pressure adjusting device for the two liquid valves of the present invention can be configured as follows. The two meshing members are formed to include gears or fan blades.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. With reference to FIGS. 1 and 2, the valve body 1 of the present invention is provided with water intake ports 11 and 12 and a water discharge port 13, so that two different liquids flow in from the water intake ports 11 and 12, respectively. At the same time as flowing out of the spout 13. Since the control valves 14 and 15 are provided at the inlets of the two water intake ports 11 and 12, respectively, the inflowing liquid is controlled by the control valves 14 and 15. A pressure adjusting device 2 is provided at a place where the liquids meet. The meshing members 21 and 22 are provided in the pressure adjusting device 2, and the meshing members 21 and 22 mesh with each other by the shafts 16 a and 16 b of the valve body 1 and rotate. It is formed freely. Meshing member 2
1 and 22 are assembled to the bottom of the valve body 1 by the removable bottom cover 18, so that the meshing members 21 and
Reference numeral 22 is formed so as to rotate in a fixed position.

[0008] The meshing members 21 and 22 of the pressure regulating device 2 can be composed of gears or fan blades, and when one of the meshing members rotates, the other meshing member can also rotate by receiving transmission. The rotational force of the meshing members 21 and 22 is due to the impact of the liquid flowing from the water inlets 11 and 12, and when one of the meshing members 21 or 22 rotates, the other meshing member 21 or 22 is also transmitted. It can rotate in response to it. In this case, the liquid having a relatively low water pressure can be smoothly drawn out by the rotation of the meshing members 21 and 22 by the siphon action.

In order for the meshing members 21 and 22 to have better rotational power, a guiding portion 17 is provided on the inner peripheral wall of the valve body 1, and the guiding portion 17 is located directly in front of the water discharge port 13 and at the water intake port 11. 12 and is formed so as to substantially surround the pressure regulating device 2. Since both ends of the guiding portion 17 are formed in an arc shape, liquids having different water pressures flowing from the water intake ports 11 and 12 can be guided so as to enter the pressure regulating device 2, and thus mesh with each other. The best impact effect can be directly applied to the members 21 and 22.

[0010]

Since the present invention is configured as described above, it has the following effects. ADVANTAGE OF THE INVENTION According to the differential pressure regulator of both liquid valves of this invention, it can be widely used for the supply valve of two types of liquids of different water pressure. Further, according to the differential pressure adjusting device for the two liquid valves of the present invention, it is possible to overcome the problem that the water pressure generated when a liquid having a different water pressure flows is reduced. The present invention may be embodied in other ways without departing from its spirit and essential characteristics. Accordingly, the preferred embodiments described herein are illustrative and not limiting.
