100x remote control floating ball valve

1100x remote control floating ball valveProduct working principle

When water is supplied from the inlet end of the pipeline, due to the normally open needle valve, ball valve, and float valve, water enters the water tank through the micro filter, needle valve, control room, ball valve, and float valve. At this time, no pressure is formed in the control room, and the main valve opens, allowing the water tower (pool) to supply water.
When the water level of the water tower (pool) rises to the set height, the floating ball rises and closes the floating ball valve, controlling the indoor water pressure to increase, pushing the main valve to close, and stopping the water supply. When the water level drops, the float valve opens again, the water pressure in the control room decreases, and the main valve opens again to continue supplying water, maintaining the set height of the liquid level.

2、 Key points for the design and selection of hydraulic control valves

(1) The hydraulic control valve used in engineering is a product that has been inspected and qualified by the manufacturer, with complete identification and technical documentation that meets the requirements.

(2) According to the functional requirements, select the type of valve, and then determine the material of the valve body and sealing parts based on the pipeline conveying medium, temperature, building standards, and owner requirements. Common valve body materials include cast iron, copper iron, copper, plastic, etc. Common sealing surfaces and lining materials include copper alloy, plastic, steel, hard alloy, rubber, etc. The valve body material should match the pipeline material.

(3) The nominal pressure of valves varies in different levels such as 0.6, 1.0, 1.6, 2.5, and 4.0 MPa. The working pressure of the medium transported by pipelines should be lower than the nominal pressure value of the valve.

(4) The installation of hydraulic control valves in engineering should have sufficient space for management, operation, installation, and maintenance, and should comply with the requirements of pipelines for valves.

(5) When using flange connections for pipelines, hydraulic control valves with flange connections should be used; When using groove type connections for pipelines, hydraulic control valves with groove type connections should be used.

(6) Water control valves should be installed on pipelines with unidirectional flow of the medium.

(7) The direction of the arrow on the main valve body of the hydraulic control valve must be consistent with the flow direction of the pipeline system.

(8) There should be no air blockage or obstruction in the hydraulic control valve pipe section. Automatic exhaust valves should be installed in gas storage sections such as pipeline locations.

(9) When installing the valve horizontally, the valve cover and stem should face upwards. When installed vertically, the valve cover and stem should face outward.

(10) Strength and tightness tests should be conducted before valve installation.

(11) The strength and tightness tests of valves shall comply with the following regulations.

A、 The strength test pressure of the valve is 1.5 times the nominal pressure;

B、 The tightness test pressure of the valve is 1.5 times the nominal pressure;

C、 The test pressure should remain constant during the duration of the test, and there should be no leakage on the shell packing and valve disc sealing surface;

D、 The duration of valve testing shall be as shown in the table above.
