The lining fire hose is a kind of firefighting product. It must have its own characteristics. The main feature is the use of high quality strong wire weaving, so it is subject to high pressure, wear resistance, mildew resistance and hard Leakage, low resistance, polyurethane liner lining for durability and no leakage, can also be bent and folded at will, free to move, easy to use. This is its characteristic, and it is also a good point that it can play a good role in fire protection work.

A lined fire hose is a fire-fighting product that can deliver water or liquid fire-extinguishing agents to a fire site for fire fighting. It is an important supporting equipment for fire hydrants, fire engines and fire pumps; it is a fire-fighting equipment that must be in hotels, office buildings, airports, stations, warehouses and other places. So a lined fire hose is a very important part of our lives, it protects our lives from harm, so you don't have to look down on it!

The flow indicator is still quite technically demanding, and its performance will be low if it is subjected to tremendous working pressure; and its delay performance, the delay time of the flow indicator with delay function should be adjustable But if you don't have it, you won't adjust it easily! The requirements for corrosion resistance are also very high: the water flow indicator is subjected to a corrosion test in accordance with the standard, and any part of the test cannot be subjected to corrosion damage such as cracks that affect performance. Its impact resistance: after three times of 6.8J energy impact, there must be no loose parts to hinder the flow indicator action. After the test, the outer casing of the water flow indicator shall be inspected. If the outer casing is broken without affecting the action of the water flow indicator, it is acceptable. If the outer casing is used for dust or moisture, and the outer casing is broken, the water flow indicator is unqualified. These can be seen that the water flow indicator is very high in technical requirements, so be sure to master enough technology to operate!

The pressure switch is a high and low pressure protection control, steam service and power station widely used in household, commercial and automotive refrigeration systems. It can also be used for high and low pressure protection control of various equipment tools. However, in the selection of the pressure switch, the following points should be noted: 1. The necessity of explosion-proof: The explosion-proof form is divided into explosion-proof type and intrinsic safety type, and most of Nagano products are explosion-proof type. 2. Do you need to bring instructions: according to customer instructions. 3. Number of contacts: one contact (one output) or two contacts (two outputs). 4. Determination of set value and pressure range: The recommended setting range is between 30% and 65% of the pressure range, and the settable range is between 15% and 90% of the pressure range. 5. Is there a pulsation: If the pressure is pulsating or vibrating, a throttle valve is required to suppress the damage of the pulsating pressure to the meter.
