丹富斯遥控浮球阀工作原理
当管道从进水端给水时,由于针阀、球阀、浮球阀是常开的,水通过微型过滤器、针阀、控制室、球阀、浮球阀进入水池,此时控制室不形成压力,主阀开启,水塔(池)供水。当水塔(池)的水面上升至设定高度时,浮球浮起关闭浮球阀,控制室内水压升高,推动主阀关闭,供水停止。当水面下降时,浮球阀重新开启,控制室水压下降,主阀再次开启继续供水,保持液面的设定高度。

Dan fuss remote-controlled floating ball valve consists of the main valve, needle valve, ball valve, ball valves, hydraulic control micro filter, etc to take over the system, after setting, automatic control level. Remote control float valve directly using the liquid level control, and do not need other devices and energy sources, convenient maintenance, high accuracy of liquid level control, is not affected by water pressure, the sealing is reliable. 100 x remote-controlled floating ball valve products are widely used in high-rise buildings, living areas, such as water supply pipe network system of liquid level control of water tower, pool and other facilities.
Dan fuss remote-controlled floating ball valve working principle
When the pipeline from the inlet water supply, because of the needle valve, ball valve, floating ball valve is normally open, water through the micro filter, needle valve, control room, ball valve, floating ball valve into the pool, the control room not formation pressure, the main valve opens, supply water towers (pool). When a water tower (pool) rose to the surface of the setting height, floating ball float close floating ball valve, control indoor water pressure increases, promote the main valve closed, stop water supply. When the water drop, floating ball valve reopens, control the water pressure drop, the main valve to open again continue to water supply, set to keep the liquid surface height.
Dan fuss hydraulic control valve design and selection
(1) type in the application of hydraulic control valve is a factory inspection, all kinds of logo is complete, the product technical information to meet the requirements.
(2) according to the functional requirements, select the valve type, and then according to the pipeline medium, temperature, building standards and the owner to ask and so on, to determine the valve body and the material of sealing parts. Commonly used valve body materials have cast iron, copper, iron, copper, plastic, etc. Commonly used seal face and lining material have copper alloy, plastic, steel, cemented carbide, rubber, etc. The valve body material should match the piping material.
(3) the nominal pressure of the valve are 0.6, 1.0, 1.6, 1.0 and 1.6 MPa at different levels, such as pipeline medium, its working pressure should be less than nominal pressure value of the valve.
(4) of hydraulic control valves in the project should have enough space, so that the management, operation, installation and maintenance, and should accord with the requirement of pipe to the valve.
(5) pipe with flange connection, the flange connection of the hydraulic control valve should be adopted; Line using the groove connection, should adopt the groove connection of the hydraulic control valve.
(6) water control valve should be set on the road at the pipe of unidirectional flow medium.
Hydraulic control valve (7) the main direction of the arrow on the valve body must be consistent with the piping system flow.
(8) by the hydraulic control valve, gas section should not have air blocking resistance phenomenon. In the aeration pipe network highest position such as deposit Should be set up automatic exhaust valve.
(9) when mounted horizontally, the valve cover, stem should be facing up. Vertical installation, valve cover, stem should be outward.
(10) valve strength and leak test should be obtained before installation.
(11) the strength of the valve and leak test shall meet the following requirements.
A, the valve strength test pressure is 1.5 times the nominal pressure;
B, valve leak test pressure is 1.5 times the nominal pressure;
C, test pressure in the test duration shall remain unchanged, and shell packing and clapper sealing surfaces without leakage;
D, valve test duration according to the table.
