Installation of remote control float valve

Remote control float valve installation techniques: remote control float valve should be set in the pool or water tank on the water pipe, should be installed horizontally, valve cover up. Its control catheter and float set should meet the following requirements:

A, remote control float valve control catheter should be fully fixed in the pool or water tank, control the total length of the catheter should be more than 8cm, the float center should be away from the inlet 1cm or inlet pipe should be taken wave device.

B, the same pool or tank above the overflow level above the water level should be to prevent the return of pollution siphon phenomenon of holes, aperture 10mm, hole center and overflow water level should meet the requirements.

Life of the water supply system adjustable valve, the valve before and after the valve maximum pressure difference of not more than 0.4MPa; in a quiet place (residential, hotel, hospital) living water supply system adjustable valve before and after the valve Differential pressure should not be greater than 0.3MPa. When the maximum pressure difference between the front and the valve after the adjustable water supply valve is above the above stipulation, the adjustable pressure reducing valve should be set in series or take anti-noise measures. When the adjustable diameter of the valve is not greater than 50mm, should be used linear pressure reducing valve; when more than 50mm less than 100mm, it is advisable to use pilot valve. Some of the high-rise civil buildings (such as hotels, homes and hospitals) that are extremely uneven in water consumption, in the case of quiet requirements, adjustable rectifier should be set in parallel. Reducing parallel settings should meet the following requirements:

A, according to the main and auxiliary valve work and flow characteristics to determine the main and auxiliary valve diameter. The general auxiliary pressure valve should be smaller than the nominal diameter of the main valve less than two or more;

B, deputy pressure relief valve after the pressure should be better than the main valve after the high pressure valve 00.020 ~ 0.035 MPa (dynamic pressure value)

Note: A, different diameter parallel set, through the design flow should be different nominal diameter or adjustable pressure valve at the same time work to calculate.

B, Reducing Parallel Settings Only for Adjustable Pressure Reducing Valves.

C, the main pressure reducing valve for the direct pressure reducing valve, the parallel pressure valve can not be parallel.

D, reducer parallel set, the main relief valve can no longer be connected with the diameter of the valve.
