KR20010110377A - Butterball Strainer and Due check By-pass type valve (One stop valve) - Google Patents

Abstract

Conventional piping has many unreasonable points when considering the load and workability of piping lines using valves that require each function. We developed a composite valve that combines the functions of the valve, and the function was created by combining the existing Butterfly and Ball and the Strainer, By-pass and Due Check Valve.

The valve can be used for general and firefighting. The function is to function as butterfly ball, to act as a strainer in the ball, to remove this substance, to install a valve to prevent backflow, and to prevent vacuum or differential pressure in the pipe. By-pass valves were installed to control pressure differentials as they occur. They are also fitted with switches to meet the needs of firefighters and consumers, and are designed to check valve status where required.

This valve is expected to contribute greatly to cost reduction and corporate competitiveness.

Description

Multifunctional compound valve {Butterball Strainer and Due check By-pass type valve (One stop valve)}

Looking at the previous piping, there was the trouble of installing the ball valve, the strainer role of each function, the role of the check valve, and the by-pass for removing the differential pressure. We designed and designed a valve that can be used as one, and it is expected that there will be a significant change and development of piping through this valve.

As a result of efforts to improve, the rubber is coated on the outside of the ball to improve airtightness, and it can act as a strainer inside, and it is designed to prevent backflow. By-pass and gear box can be attached at the request, so it can be used for firefighting and general use. Therefore, when using for firefighting, it is easy to check the operation status of the valve at the place required by the consumer. It was possible to check the opening and closing state of the valve by attaching a device directly connected to the drive of the disk, this pipe valve had the disadvantage of installing By-Pass separately from the individual valves in the prior art.

In order to reduce weight in the future, new materials are used to make light and solid valves, and domestic valves are also demanding technology-intensive composite valves.

Butterball Strainer and Due check By-pass Flange type valve

Specification 50A 65A 80A 100A 125A 150A 200A 250A 300A

The drawings below are designed to easily assemble the repair work using bolts so that the flanges can be reused when the previous pipe is to be repaired as a schematic diagram.

It is composed of spheroidal graphite cast iron, bronze, stainless steel, rubber, etc. The valve can be used for general and firefighting, and it functions as a butterfly ball and acts as a strainer in the ball. A valve to prevent backflow was installed, and a bypass valve was installed to control the pressure difference when a vacuum or differential pressure occurred in the pipe.

It is also equipped with a switch to meet the needs of firefighters and consumers, and is designed to check the condition of the valve where required.

This valve is expected to contribute greatly to cost reduction and corporate competitiveness.

As the weight per unit is reduced compared to the previous valve, the load on the piping line is reduced, the workability is excellent, and the cost reduction effect is secured. Feed
