Adjustable automobile tail plate flow control valve DLF-08

When the one-way valve is difficult and can't be repaired, be sure to buy a new one-way valve. Before buying one-way valve, first understand the function and structure of one-way valve, which is conducive to better purchasing a suitable one-way valve. Let's take a look at what a one-way valve is and how to buy a suitable one.

Custom check valves are also called globe valves or check valves. In hydraulic transmission device, preventing oil discharge or reverse fluidity is used to prevent oil discharge or reverse fluidity. One-way valve has two types: transmission data type and inclination angle type. The one-way valve for transmitting data is assembled on the pipeline with flange connection. There are three methods of inclined angle check valve: flange connection, platform connection and loose flange.

Structure of one-way valve:

1. According to the structure: lifting mechanism check valve, stacked check valve and swing check valve.

2. Check valves of lifting mechanism: vertical check valves and upright check valves.

3. Rotary check valves: single-flap check valves, double-flap check valves and multi-flap check valves.

4. According to the connection method, it is divided into flange connection check valve, electric welding check valve and flange check valve.

Selection of one-way valve:

1. One-way valves are only suitable for controlling the fluidity of liquid chemicals. Ningbo vacuum solenoid valves are not suitable for very large solid particles and chemicals with strong adhesion. Check valves with low voltage requirements include disc check valve, diaphragm check valve and column elevator check valve. Whether the ball check valve with medium and low voltage requirements is damaged or not, the disc check valve and diaphragm check valve with low voltage requirements.

2. Diaphragm one-way valve is used for low-pressure pipeline which is easy to cause water damage. The diaphragm on the one-way valve at this time of unilateral cartridge valve can very well offset the water hammer when liquid chemicals flow.

3. The stacked one-way valve can be used for pipelines that require water hammer when closing the one-way valve.
