The difference between gate valves and globe valves

1. Structure Difference The valve core of a gate valve is a gate plate (flat plate or wedge-shaped), and its movement mode is up and down, similar to lifting a sluice gate. The gate plate moves perpendicularly to the direction of the medium flow. The valve core of a globe valve is a valve disc (circular disc-shaped), and its movement mode is front and back pushing and pulling, moving along the axis of the valve seat. It is like a piston. 2. Flow Path Difference When the gate valve is fully open, the flow path is straight-through, and the medium can pass through without any obstruction. Therefore, the flow resistance is extremely small. The flow path of the globe valve is S-shaped and bent. The medium must bend around the bend to pass through, so the flow resistance is relatively large. Even when fully open, there is still some resistance.

Three-piece forged steel ball valve: Structural analysis, performance advantages and application scenarios

The three-piece forged steel ball valve is a type of valve that achieves the on-off or regulation of the medium by rotating the ball. Its core structure consists of the valve body, the ball, the valve stem, and the sealing components. It features high pressure resistance, corrosion resistance, and ease of maintenance, and is widely used in industries such as petroleum, chemical engineering, and energy. The following analysis is conducted from four dimensions: structure, performance, application, and selection suggestions.

What are the precautions to be taken during the use and installation of the high-pressure check valve?

The precautions for high-pressure check valves cover various aspects such as pre-installation preparations, installation process, operation usage, and regular maintenance. Only by strictly following these precautions can the high-pressure check valve operate normally and ensure safety in high-pressure environments.
