Description

Dilution valve

The present invention relates to a water dispenser valve, and more particularly, it is possible to easily detect the flow of water inside the valve that is difficult to visually identify, and can be used in various fields. It is possible to detect the flow of running water even if it is installed within the reach of the user's hand, so that problems such as leaks and blockages can be easily grasped. It is related to a dilution valve that is equipped with a protective cap on the guide stand in contact with the contact to improve the sealability and at the same time can be partially replaced when worn, reducing the management cost.

The conventional water flow detection device has a swing chuck type check valve structure, and the inside of the main body is divided into a primary chamber and a secondary chamber by a separating wall. A communication port is formed in the dividing wall, and the communication port has a structure that can be opened and closed by a valve valve that is etched.

The water flow detection device is always in a state in which the valve body is closed, and the pressure of the secondary side decreases due to the opening of a sprinkler head connected to the secondary side, whereby the valve body rotates and flows from the primary side to the secondary side. Occurs.

In order to detect the rotation of the valve body at that time and output a signal, a shaft fixed to the valve body protrudes out of the main body, and a limit switch is activated when the rotation angle of the shaft reaches a predetermined angle or more. A horizontally long lever is provided on the shaft, and the displacement amount caused by the rotation of the valve body is amplified to output a signal by a limit switch provided near the tip of the lever (for example, a patent). See Document 1).

In addition, as another configuration, an arc-shaped protrusion is formed on the primary side of the valve element, and the flow area of the communication hole for communicating the primary side chamber and the secondary side chamber is reduced, which flows from the primary side to the secondary side. In some cases, the amount of rotation of the valve body due to water flow is amplified, and the displacement is detected by a limit switch provided near the valve shaft, and a signal is output (see, for example, Patent Document 2).

However, the oil / water detection device is formed with arc-shaped projections on the primary side of the valve body, but it is difficult to process arc-shaped projections, and it is difficult to form them unless they are produced in a dedicated shape. In addition, in order to produce a mold for forming an arc-shaped protrusion by the size of the water flow detection device, it is very expensive to manufacture a mold.

The oil / water detection device is provided with a lever or arc-shaped protrusion as an amplifying means so that it is easy to detect rotation of the valve body due to the water by the limit switch. It is also possible to use a linear projection by replacing the arc-shaped projection, which is the amplification means described in Patent Document 2, but if the projection is too long, projection may be caught on the inner wall of the flow path, which may inhibit the opening of the valve body.

The settled portion is a space in which the disk 30 moved upward to communicate with the tubular body is settled, and the length protruding upward from the pipeline of the body is formed at least greater than the height of the disk to open the tubular body of the fluid ( 30) it is preferable not to disturb the flow of the fluid.

Here, the disk 30 placed inside the body 20 moves up and down by the rotation of the screw 40 to interrupt or open the tubular body. In other words, the disk 30 is moved downward by the screw to block the flow path of the tubular body, and the fluid is interrupted. On the contrary, the disk 30 is moved upward and positioned in the settled portion 21 to flow the fluid. The disk 30 is usually formed of a circular plate body having a predetermined thickness so that the outer circumferential surface of the disk is in close contact with the pipeline of the body when it is interrupted. Therefore, the disk 30 is formed with guide grooves 23 on both sides of the body 20 in contact with the outer peripheral surface of the disk to prevent being pushed by the hydraulic pressure, the outer peripheral surface of the disk 30 corresponding to the guide groove The guide stand 31 is formed so that the guide stand 31 is inserted into the guide groove 23 to be slid up and down, thereby preventing it from being pushed by hydraulic pressure.

A thread is formed.

In such a structure, the disk 30 is formed of a synthetic resin having a material having a constant elastic outer surface to improve watertightness. The synthetic resin generates wear faster than the metal material, so that the guide 31 is guided. As the groove is moved from the groove, wear of the guide guide is rapidly generated.

Therefore, the watertight cap 32 is detachably mounted to the guide stand, which is a part of the wear, to facilitate replacement by wear, and to reduce the maintenance cost.

The watertight cap 32 is preferably formed in a size that can cover the front surface of the guide base 31 sliding in contact with the guide groove, reducing the thickness of the guide base 31 by the thickness of the watertight cap 32 Can be installed.
