The present invention relates to an opening / closing amount display device of a chemical pipe open / close valve, and more specifically, it is possible to immediately know the current opening / closing, capacity, etc. from the outside with the naked eye, mechanically, or electronically. It relates to an opening and closing amount display device of the chemical pipeline switching valve that can be dealt with.

In general, a valve is a device that is installed in the middle of a pipeline or in a container and controls the flow rate, pressure, and the like of a fluid, and its type varies depending on the purpose. Generally, most widely used stop valves (glove valves and angle valves), slew valves, check valves, pressure reducing valves, etc. are a type of Kokdo valve. The type and dimensions of the valve are specified in the standard.

Stop valves are widely used as shut-off devices without cost. There are globe valves in the same direction and angle valves that bend at right angles. There are threaded and flanged connections to the pipe. This valve is sure to work and is inexpensive, but has a relatively large fluid resistance and a large pressure loss.

A slot valve is a valve in which a disk-shaped valve closes the pipeline in a right angle to block flow. The slot valve is pulled open by a screw or the like, and the flow rate is controlled by a pulling amount. There are parallel slide valve and wedge valve by operation of the valve. It is used in the case of large capacity because the pressure drop is lower than the stop valve and the length of the valve casing can be short.

The check valve refers to a valve that allows flow in only one direction and prevents flow in the opposite direction in order to prevent danger or ensure function. The pressure reducing valve is a valve for automatically reducing the pressure of the fluid and keeping the pressure after the pressure reduction constant. The valve is opened with a spring or diaphragm. When installing this valve in a pipeline, a ball valve is usually installed on the high pressure side and a safety valve or an escape valve on the low pressure side. An escape valve is a valve which flows a part of fluid out in order to prevent the increase of the pressure by the reduction of a discharge amount.

The throttle valve is a valve that regulates the flow rate. Pressure does not matter. The safety valve is a valve for releasing a part of the fluid when the pressure exceeds a certain limited value and suppressing the increase in pressure.

The cock is used to rapidly block or change the flow of fluid by the rotation of a sliding surface that prevents the flow of gas.

The butterfly valve is used by placing the disc in the pipeline and adjusting the opening by the rotation of the disc. The butterfly valve is simple and does not have any major trouble in the piping space.

The material of the valve is bronze, cast iron, cast copper at medium temperature, medium pressure, bronze at high temperature and high pressure, and high pressure at high temperature. I) alloy steel is used.

As a measure of judgment in opening and closing such a valve, it is the experience of the skilled person, and sometimes it is dependent on the feeling of the worker and personal skill when the branch needs to diverge from the middle part, and when the judgment is wrong, a big error occurs. There was a problem that greatly enlarges.

In addition, since the current state is not known, there is a problem in that it is directly exposed to various risks and its ability to cope with it is reduced.

The present invention is to solve the problems as described above, it is possible to immediately know the current opening and closing, capacity, etc. from the naked eye or mechanical, electronically from the outside, if you need to adjust the capacity in a hurry chemical body opening and closing can be easily adjusted It is an object of the present invention to provide an opening / closing indicator of a valve.

In order to achieve the above object, the present invention is an inlet is formed in one side end, the outlet is formed in the other end, the center is protruded to the upper side and the left and right sides of the inlet and the center is open Sealing protrusions forming the inclined surface to each of the outlet side is formed, the lower body of the synthetic resin material formed on the upper surface of each corner of the fastening through the bottom;

Through-holes are formed on the extension line of the fastening through-holes with a rectangular plate body that is an elastic member, and a valve shaft having an elevating screw portion is axially coupled to the center thereof. A diaphragm for opening or blocking the flow;

Fastening holes are formed on the through-hole extension line by the lower open body fixing the diaphragm to the upper surface of the lower body, and fastened to the fastening through-holes through the through-holes by fastening bolts, and corresponding to the lifting screw portion at the center. An upper body made of a synthetic resin material having an inner threaded portion and a support ring body having a release preventing jaw at the top thereof is inserted from the bottom thereof to form an axial support hole for supporting the upper part to protrude;

In the center of the body is formed a coupling hole in which the upper part of the support ring body is squarely fitted into the protrusion is inserted into the upper portion, the body is fixed by a snap ring on the upper outer periphery of the support ring body, the upper surface of the coupling hole is a circular working recess A handle having a seating groove formed inward at an upper surface of the operation recess, and having a plurality of handles protruding outward at an outer circumference of the body;

A guide tube having a cylindrical shape inserted into an upper end of a valve shaft of the diaphragm and fixed by an axial bolt, and having a guide projecting to a right triangle on one side of the outer circumference;

A circular plate is inserted into the seating groove of the handle, and the center of the body is formed with a guide tube through which the guide tube penetrates, and on one side of the guide tube hole, the guide hole is formed so as to penetrate the upper surface of the guide hole. It is characterized in that it has an opening and closing amount display panel is formed, the opening and closing amount display unit for displaying the opening and closing degree of the diaphragm numerically.

In addition, a plurality of insertion grooves are formed on an upper surface of the body of the handle, and a plurality of insertion protrusions protruding downwardly corresponding to the insertion grooves from the upper part of the handle to protect the guide tube and the closing amount display plate from external shocks. It is characterized by further comprising a protective cap of the transparent material.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.
