Description

Flow indicator for valve

The present invention relates to a flow rate indicator of the valve, and more specifically, the current opening and closing, capacity, etc. can be immediately known from the outside with the naked eye, mechanically, or electronically, so that the capacity can be easily adjusted by coping with the capacity. It relates to the flow rate indicator of.

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, the most widely used stop valves (glove valves and angle valves), slew valves, check valves, pressure reducing valves, etc. are a kind of kokdo valves. 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 in which the direction of the flow is bent 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 sends a part of fluid outward 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 limit 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 conventional 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 quickly adjust the capacity of the valve can be easily adjusted by adjusting the capacity The purpose is to provide a flow rate indicator of.
