Safety accessories for pressure vessels

Shandong Tianglian always adhere to the "quality-oriented", with high quality products and perfect after-sales service to win the trust of our customers and a high degree of praise, the product sells well at home and abroad. The following is an introduction to the pressure vessel safety accessories are.

Pressure vessel safety accessories: 1, safety valve: the role of the safety valve is when the pressure in the equipment exceeds the specified requirements automatically open, release the pressure over, so that the equipment back to normal working pressure. After the pressure is normal, the safety valve closes automatically. Safety valve calibration, it is strictly prohibited to add weights, moving weights, the valve flap jamming and other means to arbitrarily increase the safety valve setting pressure or make the safety valve failure. 2, pressure gauge: the range of the pressure gauge should be compatible with the working pressure of the equipment, usually for the working pressure of 1.5 ~ 3 times, preferably 2 times. Pressure gauge dial should be marked with a red line, pointing out the maximum allowable working pressure. The connection pipe of the pressure gauge should not be leaking water or steam, otherwise it will reduce the indicated value of the pressure gauge. 3, rupture disc 4, thermometer 5, level gauge 6, pressure reducing valve 7, emergency cut-off device: its role is to rupture the pipeline and its accessories and misoperation or tanker trucks near the occurrence of fire accidents, can be an emergency to close the valve to quickly cut off the source of gas, to prevent the accident from spreading and expanding. 8, open the door of the pressure vessel safety interlocking Device: open the door safety interlock alarm device is to prevent open the door type pressure vessel to prevent the operation of the accident effective measures. Its role is: a, when the open door to reach a predetermined closing part of the interlocking control function before the pressure can be raised to run; b, when the internal pressure of the pressure vessel is completely released, the safety interlocking device is disengaged before the open door can be opened to interlock the interlocking linkage function; c, with the above action synchronised alarm function.
