Description
Technical field
The utility model relates to valve field, relates in particular to a kind of electric remote control float valve.
Background technique
At present, hydraulic automatism control valve is generally used for the various water tanks (pond) in industrial and mining enterprise, civil building, the automatic water supply system of water tower, and can be used as normal-pressure boiler circulating water control valve.It comprises the liquid chunnel that liquid entering hole and liquid outlet form, and is provided with the sealed mouth of sealing fluid circulation road while being convenient to cut off in liquid chunnel.Hydraulic control valve complex structure of the prior art, works not steady, in range of working pressure, opens inconvenience, is prone to impact of water hammer, and liquid level control accuracy is low.
Model utility content
The utility model, in order to overcome deficiency of the prior art, provides a kind of electric remote control float valve.
The utility model is to be achieved through the following technical solutions:
A kind of electric remote control float valve, mainly by main valve, needle type regulating valve, ball valve, electronic float switch, float valve, solenoid valve and conduit composition, described main valve comprises the valve body that is provided with liquid entering hole and liquid outlet, between liquid entering hole and liquid outlet, form liquid chunnel, valve body is provided with flap and valve gap, the valve cavity part composition main valve control chamber of flap upper end and valve gap lower end, flap is arranged on the valve rod in valve body, the lower end of described flap is provided with seal ring, the lower end of described seal ring is provided with seal joint, upper end at flap is provided with diaphragm, the upper end of described diaphragm is connected with diaphragm platen, the back segment of described valve rod is provided with spring, one end of spring is connected in the groove of diaphragm platen upper end, the other end is connected in valve gap, between valve gap and the rear end of valve rod, valve rod copper sheathing is installed, the upper end of described valve gap is connected with suspension ring.
Between valve body liquid entering hole and main valve control chamber, be connected with needle type regulating valve by conduit, on main valve control chamber, be also connected with successively ball valve, solenoid valve, float valve and electronic float switch by conduit.
Compared with prior art, the beneficial effects of the utility model are: by adopting said structure design, under normal operation, solenoid valve power-off, in opening state, only has float valve to play and control water level effect.
When tank water bit line is during lower than user's designated water level line, float valve in pond is opened, press water in main valve control chamber leaks into pond by conduit, pressure in main valve control chamber decrescence and level off to zero, main valve entrance point has the WATER AS FLOW MEDIUM of pressure to act on flap, when the active force of its generation overcomes total power of the power of the spring in main valve control chamber and the power of flap deadweight, flap rises, main valve is opened, pipe network system starts to supply water to pond, after flap is opened, the pressure in main valve control chamber equates with the pressure of main valve entrance point.
In the time that tank water bit line reaches user's designated water level line, the ball float of the float valve in pond is closed at buoyancy of water effect float downward, pressure in main valve control chamber equates with the pressure of main valve entrance point, because the area of the Area Ratio flap of diaphragm wants large, although the pressure in main valve control chamber equates with the pressure of main valve entrance point, but the water with pressure on diaphragm with flap on the active force that produces different, the former is large, flap is had and move down the trend of closing main valve, so, flap is at the active force that has the counter-flow media of certain pressure to produce, the active force of spring, under the effect of three kinds of active forces of power of flap deadweight, automatically close.
In the time that in pond, float valve is malfunctioning, when water level exceedes normal water level 10cm, the action of electronics float switch, solenoid valve energising is closed, cutting-off controlling pipe water route, main valve is slowly closed, and plays dual fail-safe and controls in time water level effect.
By the supravasal needle type regulating valve that regulates main valve entrance point to be connected with main valve control chamber, can regulate the time of main valve flap opening and closing, effectively eliminate, control the generation of water hammer.
The hydraulic control valve that the utility model provides uses hydraulic principle control, novel structure, advantages of simple, and stable working is reliable, in range of working pressure, open flexibly, without impact of water hammer, convenient for installation and maintenance, liquid level control accuracy is high, water level is not subject to the variation of pressure medium and change and the tight good characteristics such as water-tight, flexible durable.
