What is a safety valve?
The safety valve can automatically open and close according to the working pressure of the system and is generally installed on the equipment or pipeline of the closed system to protect the safety of the system. When the pressure in the equipment or pipeline exceeds the set pressure of the pressure-reducing valve, the pressure-reducing valve will be automatically opened to ensure that the medium pressure in the equipment and pipeline is lower than the set pressure, so as to protect the equipment and pipeline and prevent accidents.
Safety valve characteristics
1. Accurate and constant safe and stable pressure. In case of overpressure, the pressure relief valve can be fully opened to relieve pressure in time.
2, the closing speed is adjustable, eliminating pressure fluctuations.
3, diaphragm transmission mechanism to minimize the operation lag.
4, can be installed in any position, without changing the pressure set value or removed from the pipe and can be repaired and inspected.
The safety relief valve is located where
The safety valve is generally installed at the beginning of the hydraulic or pneumatic system. The system behind the hydraulic pump is generally equipped with a one-way valve. The safety valve is generally behind the one-way valve to regulate the pressure of the system. Generally, the safety valve is required to have good sensitivity, that is, it can open the circuit unloading in time after overpressure, the control pressure should be stable, and there can be no internal leakage.
How to install the safety valve？
The safety valve is installed vertically, and the installation position is as close as possible to the protected equipment or pipeline. Install in a place that is easy to repair and adjust, with enough space around.
The safety valve is a special valve in which the opening and closing parts are normally closed under the action of external force. When the pressure of the medium in the equipment or pipeline rises more than the specified value, the special valve can prevent the pressure of the medium in the pipeline or equipment from exceeding the specified value by discharging the medium outside the system. The safety valve belongs to the automatic valve, mainly used in boilers, pressure vessels, and pipelines, control pressure does not exceed the specified value, and plays an important role in personal safety and equipment operation protection. The injection safety valve must be pressure tested before use.
