Analysis of Working Principles of High Temperature Check Valve
High-temperature check valve has a disc-shaped valve flap, which rotates around the axis of the seat, and due to the streamline design of the internal channel, it has less flow resistance than the butterfly check valve. It is suitable for low flow velocity and large diameter occasions where the flow does not often change. However, it is not suitable for pulsating flow, and its sealing performance is inferior to the lift type. The butterfly check valve is divided into three types: single, double, and multi-lobed, mainly divided by the valve diameter to prevent the medium from stopping or reversing, and to weaken the hydraulic impact.
High-temperature check valve is a check valve that has a valve flap that slides along the vertical centerline of the valve body
The internal thread check valve can only be installed on horizontal pipelines, and the valve flap of the high-pressure small-diameter check valve can be a sphere. The shape of the butterfly check valve body is the same as that of the globe valve (it can be used interchangeably with the globe valve), so its fluid resistance coefficient is relatively large.
The structure of the lift check valve is similar to the globe valve, and the valve body and valve flap are the same as the globe valve. The upper part of the valve flap and the lower part of the valve cover are processed with a guide sleeve. The valve flap guide is simple and can freely move up and down in the guide sleeve of the valve body. When the medium flows in, the valve flap is opened by the thrust of the medium, and when the medium stops flowing, the valve flap drops by itself onto the valve seat to prevent medium backflow.
In the straight through type butterfly check valve, the direction of the medium inlet and outlet channel is perpendicular to the direction of the valve seat channel. In the vertical lift check valve, the direction of the medium inlet and outlet channel is the same as the direction of the valve seat channel, and its flow resistance is smaller than that of the straight through type.

The butterfly check valve has a simple structure and can only be installed on horizontal pipelines. It has a good sealing performance.

The pipe check valve is a new type of valve. It has a small volume, light weight, and good processing technology. It is one of the development directions of bronze check valve and brass one way check valve. However, its fluid resistance coefficient is slightly higher than the rotary type check valve.
The compression check valve is a valve used to cut off boiler water and steam. It has the combined functions of a lift check valve and globe valve or angle valve.
In Carbo bronze valve factory, Our products are only assembled after the first product passes a random inspection every two hours to check the assembly performance of the employees. We have two casting production lines with an annual output of 80 million tons of blanks. All materials are tested by the laboratory, and the test reports are kept for three years for traceability. Welcome to inquire.
