Abstract

The utility model relates to an electric pressure valve in hydraulic valves. The electric pressure valve comprises the output shaft of an electric motor device, an electric head, a pilot valve and a main valve. The electric head transforms the rotary motion of the electric motor device into linear motion to control the pilot valve, and the electric head is positioned between the output shaft of the electric motor device and the pilot valve. The electric head comprises a regulating nut, a connecting sleeve, a spring seat and a pressure adjusting spring. The electric pressure valve can be electrically controlled remotely, and can be controlled by utilizing the existing manual pressure valve. The electric pressure valve has the advantages of low cost, good performance, convenient operation and simple installation. The electric head not only can be suitable for the electric pressure valve, but also can be suitable for an electric flux valve.

Description

The utility model relates to the hydraulic pressure valve, relates in particular to the electric press valve.
Hydraulic pressure valve in the market, the controlling method of Flow valve has three kinds: i.e. hand control valve, servovalve and marginal Proportional valve.Development along with automatic technology, manually control the needs of the far distance automatic chemical control system of incompatibility, though and Proportional valve and servovalve can be realized automation control, but when in general automatic control system, using, performance have more than needed and price high, so the user pressed for a kind of electronic control hydrovalve, its performance is with generally hydrovalve is identical, can realize electric remote-control, price is cheap than Proportional valve.
The purpose of this utility model be to provide a kind of can electric remote-control, functional and electric press valve that price is more cheap.
The utility model electric press valve is made up of electronic device output shaft, pilot valve, main valve and electrical header, and electrical header is converted into straight line motion with the control pilot valve with rotatablely moving of electronic device.Electrical header is between electronic device output shaft and pilot valve, and it comprises adjusting nut, connecting sleeve, spring seat and pressure adjusting spring.The electronic device axle is the screw thread output shaft, cooperate with adjusting nut, adjusting nut places in the connecting sleeve and cooperates with connecting sleeve one end, and the connecting sleeve the other end is connected with the pilot valve adjustable side, and adjusting nut promotes to have in connecting sleeve the spring seat of pressure adjusting spring with the control pilot valve.
Fig. 1 is the electronic relief valve schematic representation of the utility model embodiment, and Fig. 2 is the connecting sleeve schematic representation, and Fig. 3 is that Fig. 2 A is to schematic representation.
Among the figure: 1, electronic device output shaft, 2, adjusting nut, 3, connecting sleeve, 4, pilot valve adjustable side, 5, spring seat, 6, pressure adjusting spring, 7, cone valve, 8, pilot valve, 9, main valve, 10, screw thread.
Below in conjunction with accompanying drawing the utility model is further described.
Pressure valve generally comprises sequence valve, reduction valve, relief valve, electromagnetic relief valve and unloading overflow valve, is characterized in that the pilot valve structure is identical, and main valve is slightly different, or increases by one, two secondary valve.With the relief valve is example, and it is made up of pilot valve and main valve, adds directional control valve on pilot valve, then is electromagnetic relief valve; Below main valve, add one-way valve and then be unloading overflow valve; Change main valve plug into open type by normal close type and then be reduction valve; Stopping up the pilot valve refluxing opening makes its independent oil return then be sequence valve.Therefore relief valve is illustrated the structure of pressure valve as embodiment of the present utility model.Manually relief valve promptly reaches the purpose of control relief valve by the cone valve in the manual adjustment pilot valve in the adjustable side of pilot valve; Proportional valve is to regulate cone valve by the motion of control electromagnet to control relief valve, and the Proportional valve price is more expensive, and the electronic relief valve of the utility model is converted into straight line motion with rotatablely moving of electronic device and regulates cone valve control relief valve by the control motor.
The electronic relief valve of the utility model embodiment comprises electronic device output shaft, electrical header, pilot valve and main valve.Electrical header is converted into straight line motion with rotatablely moving of electronic device, and electrical header is made up of adjusting nut, connecting sleeve, spring seat and pressure adjusting spring, and electronic device output screw thread output shaft becomes screw-thread fit with adjusting nut; Adjusting nut is inserted in connecting sleeve one end, and their cooperation is radial stop, moves axially cooperation, and its fit form can be triangle, quadrangle, hexagon or octagon, and circular groove milling or the like is that hexagon cooperates in the present embodiment; The connecting sleeve the other end is connected with the pilot valve adjustable side, and its Connecting format can be and is threaded or sells connection; Spring seat and pressure adjusting spring place in the connecting sleeve, and pressure adjusting spring one end places on the spring seat, and the other end props up the cone valve in the pilot valve, and for increasing tightness, spring seat is processed as groove, places seal ring; Adjusting nut can promote (or loosening) pressure adjusting spring with the control pilot valve.When electronic device rotates like this, drive adjusting nut promotion (or unclamping) spring seat and compress (or loosening) pressure adjusting spring, the rotating speed of control motor is the may command relief valve.
The utility model has adopted electronic device and electrical header to form the original Manual pressure valve of electric pressure valve replacement, its main feature is to realize the electronic control of hydraulic system pressure, be applicable to far distance controlled and concentrate on operating room (platform) control, have easy to operate, simple characteristics are installed, and can utilize original Manual pressure valve, cost is lower, functional, electrical header in the utility model electric pressure valve is not only applicable to pressure valve, also applicable to electric flow valve, has wider application prospect.

Claims (4)

1, a kind of by the electronic device output shaft, the electric press valve that pilot valve and main valve are formed, it is characterized in that the electric press valve also comprises electrical header, electrical header is converted into straight line motion control pilot valve with rotatablely moving of electronic device, electrical header is between electronic device output shaft and pilot valve, it comprises adjusting nut, connecting sleeve, spring seat and pressure adjusting spring, the electronic device axle is the screw thread output shaft, it cooperates with adjusting nut, adjusting nut places in the connecting sleeve and cooperates with connecting sleeve one end, the connecting sleeve the other end is connected with the pilot valve adjustable side, and adjusting nut promotes the spring seat compression in connecting sleeve or loosens pressure adjusting spring control pilot valve.
