Abstract
The utility model relates to a hydraulic self-control valve which is a control valve used for controlling feed water and feed liquid of the cistern and liquid storing tank automatically. The utility model comprises a valve body, a valve core and a valve holder. The utility model is characterized in that the valve core is arranged at one end of a controlling rod in the valve body; the controlling rod penetrates the control chamber; the valve body is connected with the control chamber whose control rod is provided with a piston; the end of the control chamber is provided with an end cover of control chamber; a handle is arranged at a control rod of the control chamber. The valve body is provided with a water source inlet and a cistern water carriage opening. The control chamber is provided with a back water joint and a water leaving outlet.
Description
Technical field
What the utility model hydraulic pressure internally piloted valve related to is a kind of control valve that is used for controlling automatically water storage tank, fluid storage tank water inlet, liquid.
Background technique
Float valve control is adopted in solar water heater water storage tank feed liquor control at present, and float valve is owing to factor affecting such as temperature, and working life is short, also can out of controlly cause the water tank spill-over sometimes.The water tank that has uses computer control liquid level, but the cost height, and to control power supply.
Summary of the invention
The hydraulic pressure internally piloted valve takes following scheme to realize: hydraulic pressure internally piloted valve structure comprises valve body, spool, valve seat, control room, control end cap, piston, controlling rod, be provided with valve seat in the valve body, the water port is arranged on the valve seat, the spool device is at valve body inner control bar one end, controlling rod runs through the control room, valve body is provided with water source water intake, water storage tank water delivery nozzle, valve body links to each other with the control room, device has piston on the inner control bar of control room, the control room end fitting has the control room end cap, on the controlling rod of handle device outside stretching out the control room.The control room is provided with backwater interface, surplus water out.
Hydraulic pressure internally piloted valve working principle: when the water heater water storage tank, water is inserted the backwater interface of hydraulic pressure internally piloted valve during the fluid storage tank spill-over by the spill-over reflow pipe, enter the control room, the hydraulic drive piston, piston drives controlling rod, the spool that is contained in the controlling rod end is sealed the water port on the valve seat, make the water heater water storage tank, fluid storage tank stops into water, feed liquor, unnecessary water is by flowing out in the slit between piston and the control room, connect away drainage by surplus water out, need be when water storage tank be intake driving handle push controlling rod and get final product Open valve, the water source enters water storage tank by the water storage tank water delivery nozzle through pipeline through the valve seat water inlet from the water source water intake.
Description of drawings
The utility model is described in further detail below with reference to accompanying drawing.
Fig. 1 is a hydraulic pressure internally piloted valve structural representation.
Embodiment
With reference to accompanying drawing 1, hydraulic pressure internally piloted valve structure has valve body 1, spool 2, valve seat 12, control room 5, control end cap 8, piston 4, controlling rod 6, be provided with valve seat 12 in the valve body 1, the water port is arranged on the valve seat, spool 2 devices are at valve body 1 inner control bar 6 one ends, controlling rod 6 runs through control room 5, valve body 1 is provided with water source water intake 13, water storage tank water delivery nozzle 11, water delivery nozzle 11 is connected with water storage tank by pipeline, valve body 1 and control room 5 are connected by screw thread, the joint device has seal ring 3 or sealing gasket, device has piston 4 on the 5 inner control bars 6 of control room, piston 4 has certain interval with the control room inwall, control room 5 end fittings have control room end cap 8, on the controlling rod 6 of handle 7 devices outside stretching out the control room, near valve body 1 one end device backwater interfaces 10, backwater interface 10 links to each other with the water storage tank reflow pipe by pipeline, and control room 5 the other ends are equipped with surplus water out 9.
