Self-closing valve profile
Pipeline gas self-closing valve, referred to as the self-closing valve, is installed in the low-pressure gas pipeline system, when the pipeline gas supply pressure undervoltage, overpressure, without electricity or other external power, can automatically shut down and must be manually opened device. The self-closing valve installed at the end of the pipe and the hose after the gas meter should have the function of closing the pressure loss. Pipeline gas self-closing valve for pipeline natural gas, liquefied petroleum gas, artificial gas.
Self-closing valve principle
The basic principle of pipeline gas self-closing valve is the multi-pole permanent magnet linkage mechanism which makes the permanent magnet material permanent memory according to the design requirements, and recognizes the change of the gas pressure parameter passing therethrough, and automatically when the safety setting value is exceeded Close the valve, cut off the gas source.
Self-closing valve function
1, with undervoltage, overpressure, loss of pressure automatically shut down, manual reset function. In the stop gas, abnormal gas supply, hose off, etc., automatically shut down to prevent leakage;
2, no electricity, or any external power, to achieve automatic shut down;
3, automatic work, long-term reliable, will not malfunction;
4, clear working conditions, easy troubleshooting;
5, easy to install, easy to use.
Indoor common gas leak reasons
1, gas hose aging, rupture, rat bite, hose hoops loose, accidental fall off;
2, stop gas maintenance, replacement, gas shortage, ice blocking, or third-party damage,
3, the user forgot to turn off the stove;
4, stove due to the wind, Tang Yi accidental flameout;
5, suicide
6, pressure regulator failure home, equipment (gas meter, hose) damage.
You have to keep in mind
In the gas pipeline, you can see such a device - self-closing valve. Many users are accustomed to manually closing the autoclaved valve after each use of natural gas, which is not right, often opening and closing is likely to make the autoclaved valve malfunction, causing air leaks. After each meal, you should first turn off the stove before the valve, and then turn off the cooker valve.
Users can self-closing valve working status self-test, check the method as follows: In the normal state of gas off the table before the valve, then the self-closing valve automatically closed, the flame goes out; then open the table before the valve, light the stove, if the stove can not Lit, indicating that the self-closing valve closed well, if the cooker can ignite the self-closing valve may indicate a problem.
importance
Gas self-closing valve is equivalent to the gas installed on the "protector", when the gas pipeline leaks, the pressure is too low or too high, abnormal flow, the gas valve does not need any electricity or any external power, you can automatically shut down, So as to better protect the personal and property safety.
It is understood that the installation of self-closing valve in 10 years to eliminate more than 90% of major accidents, is the most long-term and reliable equipment.
Bo burning tips
In the use of the hose if it appears aging, cracking, blistering or damaged, must be replaced. Gas hose should be used within the marked shelf life, the length should not exceed 2 meters. Gas hose should not be used near the furnace surface, so as not to be aggravated by the flame burning, do not fold the gas hose, so as to avoid clogging, affecting continuous gas supply. In particular, pay attention to the gas hose and cooker and the pipe interface, we must use the pipe clamp firmly fastened to prevent the hose loose off, leading to leaks.
