Abstract
The utility model discloses a remote control valve, whose main valve consists of a valve body, a piston and a valve cover. The utility model is characterized in that the valve body of three-way structure is vertically provided with a round control cavity and in and out channels. The water outlet is arranged under the control cavity. The circle center of the water outlet is coincided with the axis of the control cavity. The plane above the water outlet is covered with a piston with seal tape which divides the control cavity into a control room and a pressure chamber, a control hole is arranged where-between. A spring is arranged between the crown of piston and the valve cover. The external wall of the piston and the tube wall of the control ventricular are provided with a sealing ring there-between. The valve cover is provided with a control hole connected with the channel or with a small float valve via a pipe. The utility model has the advantages of compact structure and simple machining technology, and can become a remote valve with a small water valve switch and become a remote control float valve with a small float valve. The utility model has a great market prospect.
Description
Technical field
The utility model relates to a kind of remote control valve: particularly a kind of can controlling plumbing fixtures the remote control valve of switch, and can control the heavy caliber remote control float valve of liquid level.
Background technique
Known on the market large bore valves is the keying of umbellate form handwheel, handle or electro motion control valve at present.Because the working principle decision, umbellate form handwheel, handle unlatching are wasted time and energy, the keying cost height of electro motion control valve, and Sealing rapid wear, and working life is shorter.
Summary of the invention
In order to overcome the deficiency of above-mentioned valve, the utility model discloses a kind of remote control valve, utilize hydraulic self-locking sealing in the valve, leicht fallen D/A, valve is carried out telecontrol without electric energy, make valve function obtain expansion.
The technical solution adopted in the utility model is: a kind of remote control valve, comprise valve body, piston, valve gap, it is characterized in that: on the valve body of three-port structure, circular control chamber with advance, the vertical layout of water outlet, water outlet places the control chamber bottom, the water outlet center of circle and control chamber dead in line, be coated with the piston of band seal rubber pad on the water outlet on the plane, piston is divided into control room and pressure chamber with control chamber, between two Room equalizing orifice is arranged, be provided with spring between piston head and the valve gap, be provided with O-ring seal between piston outer wall and control room barrel, valve gap has control hole, is communicated with water outlet or small floating ball valve through pipeline.
The utility model compared with prior art beneficial effect is: simple in structure, and precise control, reliable operation, good airproof performance can accomplish that high and low pressure closes drop and do not leak, and makes the application area of valve obtain expansion, long service life is assembled easy to maintenance.

Embodiment
Below in conjunction with accompanying drawing structure of the present utility model and working principle are described in further detail.
Described a kind of remote control valve, comprise valve body (1), piston (3), valve gap (2), it is characterized in that: on the valve body (1) of three-port structure, circular control chamber with advance, the vertical layout of water outlet, water outlet (9) places the control chamber bottom, the water outlet center of circle and control chamber dead in line, be coated with the piston of band seal rubber pad (7) on the water outlet on the plane, piston is divided into control room (15) and pressure chamber (16) with control chamber, equalizing orifice (10) is arranged between two Room, be provided with spring (5) between piston head and the valve gap, be provided with O-ring seal (6) between piston outer wall and control room barrel, valve gap has control hole (11), is communicated with water outlet or small floating ball valve (13) through pipeline.
The utility model is used for remote control pipeline valve (seeing figure two), have a relief hole (12) at water outlet, during use at control hole (11) and relief hole (12)) between the appropriate location minor valve (14) is installed, when minor valve (14) when opening, the press water in control room (15) is communicated with pressure release by minor valve (14) with relief hole (12), make the pressure and the water outlet pressure balance in control room (15), and the pressure of pressure chamber (16) is greater than the pressure of control room (15), because of the area of circular control chamber area greater than water outlet (9), thereby generation pressure reduction promotes to move on the piston (3) and opens the valve water supply start.When minor valve (14) when closing, because of pressure and pressure chamber (16) of control room (15) average out again by through hole (10), because of the area of circular control chamber area, thereby produce pressure reduction, promote piston and move down throttle down and stops to supply water greater than water outlet (9).Go round and begin again.
When being used for remote control heavy caliber float valve, the utility model (sees figure three), go up by a flexible pipe installation small floating ball valve (13) at control hole (11), when small floating ball valve (13) when opening, the press water in control room (15) is communicated with atmosphere by small floating ball valve (13), make pressure moment in control room (15) drop to almost nil, and the pressure of pressure chamber (16) remains unchanged, because of the area of circular control chamber area greater than water outlet (9), thereby generation pressure reduction promotes to move on the piston (3) and opens the valve water supply start.When small floating ball valve (13) when closing, because of pressure and pressure chamber (16) of control room (15) average out again by through hole (10), because of the area of circular control chamber area, thereby produce pressure reduction, promote piston and move down throttle down and stops to supply water greater than water outlet (9).Go round and begin again.
Claims (4)
1. remote control valve, comprise valve body, piston, valve gap, it is characterized in that: on the valve body of three-port structure, circular control chamber with into and out of the vertical layout of water channel, water outlet places the control chamber bottom, the water outlet center of circle and control chamber dead in line, be coated with the piston of band seal rubber pad on the water outlet on the plane, piston is divided into control room and pressure chamber with control chamber, between two Room equalizing orifice is arranged, be provided with spring between piston head and the valve gap, be provided with O-ring seal between piston outer wall and control room barrel, valve gap has control hole, is communicated with water outlet or small floating ball valve through pipeline.
