[0018] Figure 1 , 2, 3, the utility model discious water cutting equipment body 1 work, sand tank 101 is filled with sand material in advance, work, pressurizing equipment pumps into the water inlet end of sand tank 101 after pressurizing, high pressure water takes away the sand material of sand tank and exports into the pipeline connected with the cutter head through the valve, then water and sand mixture are high -speed sprayed from the front end of cutter head 103 and carry out cutting operation to the surface of object (the staff carries out operation by hand holding cutter head gun handle). It needs to be explained that water cutting equipment is the existing mature technology, therefore, the application does not repeat the working principle. After AC 220V power enters the power input end of power module A1, the stable DC 12V power of power module A1's 3, 4 feet enters the power input end of wireless receiving circuit, electric proportional valve A4 and display circuit. In the new type, when the staff respectively adjusts the opening and closing degree of handle controller valve core of manual valve 3, can control the water pressure size that enters sand tank 101, the water pressure and water flow that enter sand tank 101 are relatively small when the valve opening degree is small, in this way, the water sand mixture pressure of the front side end output of cutter head 103 is low and carries out derusting operation to the surface of object, when the valve opening degree is big, the water pressure and water flow that enter sand tank 101 are relatively big, in this way, the water sand mixture pressure of the front side end output of cutter head 103 is high and carries out cutting operation to the surface of object (when the control mode of manual valve, the power of power module A1 is closed, the valve core of electric proportional valve A4 is closed). When the manual valve is closed, the staff combines the number (the voltage number that the voltmeter V shows is bigger, represents that the valve core opening degree of electric proportional valve A4 is relatively big, contrarily relatively small) of the number of voltage table V display and can adjust the valve core opening degree of electric proportional valve A4 by wireless remote control mechanism A3 in wireless mode, and then adjust the water pressure size that enters sand tank 101, realize water cutting equipment as cutting or derusting etc. use. After the staff presses the first emission key D1 or the second emission key D2 of wireless remote control mechanism A3, wireless remote control mechanism A3 will emit the first path or the second path wireless closing signal, after receiving, its 3 or 4 feet will output high level and enter the positive power input end of relay J1 or J2, and the control power input end and normally open contact end of relay J1 or J2 will be closed, in this way, the positive or negative or negative positive two power input ends of motor speed reduction mechanism M1 will be electrified, after the motor speed reduction mechanism M1 is electrified, the handle of adjustable resistance RP1 is rotated counterclockwise or clockwise by the rotating shaft of motor speed reduction mechanism M1, the resistance value of adjustable resistance RP1 is smaller or bigger, when the resistance value of adjustable resistance RP1 is bigger, the voltage between adjustable resistance RP1 and resistance R1 is bigger, the 3 foot signal voltage of electric proportional valve A4 is relatively low, the valve core opening degree of electric proportional valve A4 is relatively small, when the resistance value of adjustable resistance RP1 is smaller, the voltage between adjustable resistance RP1 and resistance R1 is smaller, the 3 foot signal voltage of electric proportional valve A4 is relatively high, the valve core opening degree of electric proportional valve A4 is relatively small.When the valve core of the electric proportional valve A4 is opened to a proper degree, the staff presses the first or second transmitting button D1 or D2 of the wireless remote control mechanism A3 again, the wireless remote control mechanism A3 transmits the first or second wireless open circuit signal, and the 3 or 4 pin of the wireless receiving circuit module A2 stops outputting high level to the positive power input end of the relay J1 or J2, the relay J1 or J2 loses power and no longer attracts the control power input end and the open circuit end of the normally open contact, so that the positive or negative power input end of the motor speed reduction mechanism M1 loses power, the shaft of the motor speed reduction mechanism M1 no longer drives the handle of the adjustable resistor RP1 to rotate counterclockwise or clockwise, and the valve core of the electric proportional valve is fixed at the opening degree. Through the above, the staff can not only manually adjust the water pressure and flow entering the sand tank through the valve, but also can adjust the water pressure and flow entering the sand tank through the wireless remote control mechanism, the wireless receiving circuit and the electric proportional valve, and the application mode is more flexible, which brings convenience to the staff. Figure 2 In the new type, the power module A1 is an AC 220V to DC 12V switch power module product; the adjustable resistor RP1 has a resistance of 47K; the resistor R1 has a resistance of 8K; the relays J1 and J2 are DC 12V; the voltmeter V is a four-digit liquid crystal voltage display meter with a range of 12V (the display surface is located outside the front end opening of the element box); the wireless remote control mechanism A3 and the wireless receiving circuit module A2 are wireless transmitting and receiving circuit module products of the TWH9236 / TWH9238 type (identical to the working principle of the wireless remote control and receiving assembly for vehicles); the electric proportional valve A4 is a small proportional integral regulating valve of the VB3100 type, which has two power input ends and one signal input end, and the higher the input signal, the greater the opening degree of the valve core, and vice versa; and the motor speed reduction mechanism M is a coaxial motor gear reducer product with a power of 10W. In the new type, the cutter head 103 can also select different jet hole diameters according to needs, so that the water jet equipment can also realize the conversion between the rust removal and cutting functions. Specifically, when the jet hole diameter of the cutter head 103 is large, the output water pressure is low, and the water jet equipment is used for rust removal, and when the jet hole diameter of the cutter head 103 is small, the output water pressure is high, and the water jet equipment is used for cutting.
