The use of quick-open mud drain valve

This series of sludge discharge valves, also known as angle-type diaphragm quick-opening sludge discharge valves, are mainly installed outside the bottom wall of various sedimentation tanks, or on the main drainage pipeline to remove sediment and dirt at the bottom of the tank and inside the pipeline. It adopts electric two-position four-way reversing valve or manual two-position four-way or directional valve centralized control, which is easy to operate and the valve can be opened and closed flexibly.

Reference standard for quick-open mud drain valve

1. Design and manufacturing standard: JB/T6900-1993;

2. Flange connection standard: GB/T9113-2000;

3. Test and inspection standards: GB/T13927-92;

4. Pressure and temperature grade standard: GB/T17241.7-98;

The working principle of the quick-open mud drain valve

JM744X diaphragm type quick-opening sludge discharge valve is an angular cut-off valve with hydraulic source or pneumatic source as the actuator. It is usually installed in a row on the outer side wall of the bottom of the sedimentation tank to remove the sediment and dirt deposited at the bottom of the tank. thing.

Diaphragm type quick-opening mud discharge valve is divided into two chambers by nylon reinforced rubber diaphragm, connected to hydraulic or pneumatic source, and controlled by electric or manual two-position four-way reversing valve to realize rapid mud discharge. The valve replaces the diaphragm with the piston without moving friction, which is more suitable for granular media such as mud, which greatly improves the service life of the valve.

Installation and maintenance of quick-open mud drain valve

1. All kinds of hydraulic and pneumatic sludge discharge valves produced by Mingguan Valve are pressure-tested according to the standard of GB/T13927-92 before leaving the factory, and there is no leakage for 2 minutes. The hole cavity is cleaned, and there is no need to disassemble and adjust the valve. It can be directly connected to the flange or valve of the same specification and pressure for installation and use.

2. The diaphragm of Mingguan valve body has good sealing performance and durability. The diaphragm is made of nylon reinforced rubber, and its service life is more than three years. It needs to be replaced after more than five years. An O-ring is installed between the valve stem and the support seat to completely prevent the occurrence of water leakage here.

3. The manual, hydraulic and pneumatic sludge discharge valves produced by Mingguan Valve are guaranteed to be used for 18 months according to the performance specifications.

Troubleshooting and troubleshooting of quick-open mud drain valve

Faced with the phenomenon that the valve cannot be opened and closed normally, it is necessary to check the following contents:

1. Whether the input voltage of the electromagnetic directional valve is normal.

2. Whether the connection is in good condition, whether there is leakage in the connecting pipe, and whether the pipeline is connected incorrectly.

3. Whether the seal is damaged and whether the driving pressure is normal

Specific processing method:

1. If the voltage is abnormal, you need to input the voltage according to the instructions;

2. If there is electricity leakage, correct the leakage problem of the connecting pipe and connect the pipeline according to the requirements of the manual;

3. If the driving pressure is abnormal, it is necessary to replace the seal and adjust the pressure.
