How to open the gas pipeline self closing valve, how to open the gas self closing valve

The method of opening the gas self-closing valve is to open the plug valve by hand, and the direction of the handle needs to be parallel to the direction of the pipeline. Gently pull the lift up and pull it to the position of the first switch.

In this way, the gas can be used normally. In the process of opening the gas self-closing valve, it must not be too forceful, otherwise it is easy to cause the lifting torque to be pulled to the position of the second gear switch, resulting in overpressure, so that the gas self-closing valve will be automatically closed, and the gas can not be used continuously.

If it is found that the lifting twist cannot be pulled up, it means that the gas self-closing valve is underpressurized, and it is necessary to find the staff of the gas company to deal with it.

Except for safety valves, the rest of the valves are ball valves. The opening and closing operation of the ball valve is very simple, that is, the valve handle is rotated 90 degrees to complete the opening and closing action. Among them, the valve handle and the pipeline direction are flat in the open state, and the valve handle and the pipeline are perpendicular to the closed state.

The valve handle has an angle of 45 to the direction of the pipeline, which is in a half-open state, and it is not recommended to be half-open in the actual use process, either closed or fully open.

2. Switching sequence.

The valves mentioned above have different functions and there is no order of opening and closing. Here we talk about the sequence of opening and closing of the cooktop valve and the meter tail valve. The cooktop valve refers to its fire switch, and their order of opening and closing is as follows:

In the order of opening, first open the tail valve, then press and rotate the cooktop ignition switch to ignite. The advantage of this is that the hose and stove can be checked for air leakage by slowly opening the tail valve, and we can close it in time to prevent serious natural gas leakage. That's a little trick, right?

In the order of closing, close the cooktop valve first after using the cooktop, and then close the meter tail valve casually. The advantage of this is to prevent the stove from flashing back, which is easy to cause damage to the stove. But here you must remember to close the tail valve.

3. Matters that should be paid attention to when opening and closing valves.

The opening and closing of natural gas valves should be slow, and it should not be opened and closed quickly;

The tail valve of the natural gas meter needs to be closed every time the gas appliance is used, and the valve in front of the meter should be closed when it is not at home for a long time;

In the event of a fire in the kitchen, the valve in front of the natural gas meter should be closed as much as possible;

Safety valves cannot be reset without identifying the cause;

Do not operate the utility natural gas valve at will.

Before opening the stove, the valve is pressed in with a half-knob and then rotated to the left, at which point a squeaky discharge sound is heard and a blue flame is seen. Then the natural gas is ignited, the switch is turned on to the maximum as much as possible during ignition, and then gently rotates the knob to the left according to the needs of the fire. Adjusting the size of the flame is also more gas-saving, and finally change the nozzle.

The method of opening the gas self-closing valve is to first open the plug valve by hand, and the direction of the handle needs to be parallel to the direction of the pipeline, and then gently pull the lifting twist up to the position of the first gear switch, and then you can use the gas normally.

Pipeline gas self-closing valve, referred to as self-closing valve, is installed on the pipeline of low-pressure gas system, when the pipeline gas supply pressure appears underpressure or overpressure, without electricity or other external power, it can be automatically closed and must be opened manually.

The basic principle of the pipeline gas self-closing valve is to magnetize the permanent magnet material according to the design requirements to make a multi-pole permanent magnet linkage mechanism with permanent memory, identify the changes in the gas pressure parameters during the passage, and automatically close the valve when the safety setting value is exceeded to cut off the gas source. No matter how good the gas is, there are always potential safety hazards, we can only use gas safely by taking precautions in advance, and the emergence of stupid valves in gas self-closing allows us to be truly prepared, safe and secure.

Benefits of Gas Self-Closing Valves:

The gas bending self-closing valve is a new thing for many people, but it is a safety device, which is used in household gas, and it is a very popular product. It is even more popular than gas alarms, and the reason is related to their protective mechanism, which is easier to use than alarms, and has a low error rate.

The advent of the gas self-closing valve can be said to be a good solution to these problems, it does not need to use electricity or other power, the use of permanent magnet materials in accordance with the design requirements to magnetize the multi-pole permanent magnet linkage mechanism of permanent memory, through the change of gas pressure parameters to identify, when the safety set value is exceeded, automatically close the valve, immediately cut off the gas source to prevent gas leakage.

Gas self-closing valve from the development to the present, in fact, has been constantly updated, so that the gas self-closing valve is easier to use and safer, because there are users or habitual to close the valve, so in the gas self-Zheng Pei stuffy closing valve added a special gas source closing valve, in daily use, to close the pipeline gas, just close the small knob on the gas self-closing valve, no need to change the knob.

A gas self-closing valve is usually a safety device installed on a household gas pipeline, which can automatically cut off the gas ** in the event of a gas leak to ensure home safety. If you need to open the gas self-closing valve, please follow these steps:1

Close the valve on the gas appliance or the valve of the gas meter to ensure that the gas appliance has stopped working; 2.Find a self-closing valve, usually on a gas meter or gas pipeline, which looks like a valve with a red handle; 3.Hold the handle of the self-closing valve with your hand, press it down and rotate it about 90 degrees, so that the arrow is aligned with the square ruler of the pipeline; 4.

After waiting for a period of time, you can reopen the valve of the gas appliance or the valve of the gas meter and restore the gas ** after confirming that there is no gas leakage. It should be noted that if you are not sure whether your operation is correct or you encounter a dangerous situation such as a gas leak, please leave immediately and contact the company or emergency rescue department to deal with it.

The gas self-closing valve is a multi-pole permanent magnet linkage mechanism that magnetizes the permanent magnet material according to the design requirements to make permanent memory, identifies the changes in the gas pressure parameters during the period, and automatically closes the valve when the safety setting value is exceeded to cut off the gas source.

1 4 Open the valve and open the manual valve (the handle spinning bridge is turned parallel to the direction of the pipeline), and gently pull up and twist to the first gear switch, which can use gas normally. If the force is too high, it will be pulled to the second gear to form an overpressure shutdown. 2 4 After using the valve opening, the valve is in the automatic detection state, and the gas makes the key durable and does not need to reset the knob, only need to close the manual plug valve (the handle is screwed to be perpendicular to the direction of the pipeline).

3 4 Undervoltage closure button can not be pulled up for undervoltage shutdown, there may be the following reasons: (1) gas outage, maintenance, gas supply pressure is too low (2) IC card gas meter arrears (3) connected stove hose leakage 4 4 overpressure closure If the button is closed from the top to the second gear position, you should immediately contact the natural gas company.

Hello dear, happy to answer your questions! Gas self-closing valve is a safety valve, usually installed on the gas pipeline, which is used to automatically cut off the gas ** when the gas pipeline leaks, so as to protect the safety of people and property.
