FAQ：
What type of device is this? What is its main purpose?
This is a gas pressure regulator specifically designed for connecting propane cylinders. Its main function is to reduce the high-pressure gas (such as propane) stored in the gas cylinder to a suitable low pressure for use, and maintain stable output pressure for subsequent operations (such as welding, cutting, or heating).
What is the outlet pressure range of this pressure reducer?
From the dial scale, it can be seen that the outlet pressure adjustment range of this pressure reducer is 0~0.6 MPa. The pointers on the dial can indicate the current output pressure value, measured in megapascals (MPa).
What does “ПパОПАН” mean on the device?
ПパОПАН “is a Russian word that means” propane “. This indicates that the pressure regulator is specifically designed for propane gas. Although many pressure reducers have universal structures, specialized pressure reducers for different gases may have differences in sealing materials, and it is not recommended to mix them.
What is the function of that red knob? How to adjust?
This red knob is a pressure adjustment handwheel.
Adjustment method: Clockwise rotation (marked with a “+” direction) will increase the output pressure; Turning counterclockwise (marked with a “-” direction) will decrease the output pressure.
Operation tip: Usually, slow rotation is required when adjusting, and observe the changes in the dial pointer.
What is the unit of “MPa” on the dial?
MPa is the International System of Units (SI) unit for pressure, officially known as “megapascals” in Chinese. 1 MPa is approximately equal to 10 atmospheres of pressure. In industrial gas applications, MPa is one of the most commonly used standard units for measuring gas pressure.
Why is this pressure regulator made of brass material?
Brass material has the characteristics of good corrosion resistance, high strength, and good thermal conductivity. For gas equipment, the corrosion resistance of brass can effectively prevent gas leakage and component damage, ensuring long-term safe use in high-pressure environments.
What are the characteristics of the pipe joint on the right side?
The right side pipe joint is usually designed with a barbed structure (sleeve type joint) for quick connection of hoses (such as rubber or acetylene pipes). This type of connector is easy to install, just put the hose on the connector and tighten the clamp, which can effectively prevent detachment.
Is there a safety valve (relief valve) on this pressure regulator?
The obvious independent safety valve structure cannot be directly seen from the picture. But in this type of pressure regulator, an overvoltage protection device is usually integrated internally. If the output pressure rises abnormally, it may automatically cut off the airflow to prevent hose rupture or equipment damage.
What preparations need to be made before use?
1.Ensure that the cylinder valve is in the closed position.
2.Check whether the appearance of the pressure reducer is intact, whether there are cracks or damage.
3.Before connecting the pressure reducer to the gas cylinder, first open the valve of the gas cylinder to blow away the dust at the interface.
4.Slowly open the valve of the gas cylinder and observe whether the pressure gauge pointer jumps or is abnormal.
What safety precautions should be taken when using?
1.Prohibition of grease: It is strictly prohibited to apply grease on the surface of the pressure reducer, as propane gas may ignite or explode when encountering grease at high temperatures.
2.Slowly open: When opening the valve of the gas cylinder, it should be done slowly to avoid damage to the instrument caused by the instantaneous impact of high-pressure gas.
3.Prohibit overpressure: When adjusting the pressure, do not exceed the rated working pressure of the equipment (0.6 MPa).
4.Regular inspection: Regularly check for leaks at the connection, and use soapy water to apply to the interface to check for bubbles.
5.Storage environment: When not in use, the cylinder valve and regulator knob should be closed and stored in a well ventilated and dry place.
