First, the system water pressure should always maintain 1.2-1.5 bar. The specific approach is:
1. Open the water inlet switch and close it when the pressure is added to 2 (pressure should not exceed 3);
2, open the last set of radiator drain valve (or floor drain valve), the system will be out of the dirty water;
3, after the "dirty water" flow is clean, close the drain valve, the second time open the water switch pressure to 2 or 3;
4. Repeatedly draining and adding water several times. The first step of rinsing is completed. However, the unloading valve and the inlet valve are opened at the same time until they are thoroughly rinsed.
5. After rinsing, fill with fresh demineralized water and raise the pressure to 1.2.
Second, do not arbitrarily change the dismantling flue, do not hang random debris and clothing on the flue.
Where the gas boiler flue is located, keep the air circulation and the environment clean and tidy. Do not stack the debris at random so as to prevent potential safety hazards.
Third, the use of sanitary hot water, it is best to adjust the temperature in the boiler temperature adjustment at the water point directly open the hot water, do not mix with cold water.
4. In the summer, long-term use of wall-hung boilers will not be used, and the water valves, gas valves, and power supplies connected to the boilers will be closed.
5. After entering the non-heat season, the boiler does not need to drain water.
PE layflat drip irrigation Water Hose/PVC irrigation pipe/ PE agriculture drip irrigation hose
Drip irrigation is a good way to save water, it ensured water flow well, with interface connection, it will not clog or deposit dirt, disperse main pipe water flow, improve irrigation efficiency.
Drip irrigation tape is one of the most effective equipment for the irrigation in the drought area, the utilization of the water could be as high as 95%. Drip line irrigation could save more water than spray irrigation, and when combined with fertilization, it could also enhance the efficiency of fertilizer by 50%.
The inner flat emitter Drip Tape, was inserted the flat emitter into a thin pipe to make it as a integrated tape. Emitter together with the tape, easy installation. With the filter window, the emitter have filter ability. Adopt labyrinth flow pass have the pressure compensation ability. The emitter spacing can be customer requirement.
For the size of products, we can produce it according to customer requirement.
