Description

Running water sensing of Sluice valve

The present invention relates to a distillation valve for oil and water detection, and more specifically, it is possible to easily detect the flow of water in the interior of the pipe that is difficult to identify with the naked eye, according to the problems such as leakage and clogged pipe and flow direction of the flow easily The present invention relates to a distillation valve for oil and water detection that can be used in various fields.

The conventional water-flow detection distillation valve has a swing chuck type check valve structure, and the inside of the main body is divided into a primary side chamber and a secondary side chamber by a partition 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-reducing water-reducing valve 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. ) 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. The horizontally long lever is installed on the shaft, and the displacement amount due to the rotation of the valve body is amplified and the signal is output 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 above-mentioned water flow detection valve is formed with arc-shaped protrusions on the primary side of the valve body, but it is difficult to process arc-shaped protrusions, and it is difficult to form them unless they are produced in a dedicated shape. . In addition, in order to manufacture a mold for forming an arc-shaped protrusion for each size of the distillation valve for water flow detection, it is very expensive to manufacture a mold.

The water-flow detection distillation valve is provided with a lever or arc-shaped projection as an amplification means so that it is easy to detect rotation of the valve body caused by running water by a 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.

As shown in Figure 1 and Figure 2, the water flow detection valve for water flow 10 of the present invention is a flange 22 is formed body 20 is coupled to the pipeline of the fluid transfer pipe, and the disk embedded in the body 30, a screw 40 for moving the disk up and down, and a water flow detection device 500 installed through one end of the dilution valve 10 to detect the flow of water therein.

The body 20 has flanges 22 formed at both ends of the tubular body to be coupled to other fluid transfer tubes, and the settling portion 21 having a hollow part is formed upward at the end of the tubular body. The settled portion is a space in which the disk 30 moved upwards 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.

In addition, the screw 40 has a locking projection 41 is formed along the outer circumferential surface is rotated only about the axis in the same position when a rotational force is applied to the outside.

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 the portion where the wear occurs, thereby facilitating replacement by wear, and reducing 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.
