Refering to Fig. 5, switch block 5 includes shell, sliding block 501 and microswitch 502, is provided with slide unit, sliding block in shell 501 are mounted on slide unit；The top of sliding block 501 is set as inclined-plane, the end of overflow valve valve rod 702 and 501 incline position of sliding block Corresponding, the bottom of sliding block 501 is in contact with the switch button of microswitch 502.

Wherein, the first elastic element, the second elastic element, third elastic element, the 4th elastic element are equal in the present embodiment For spring.

Refering to fig. 1 to Figure 10, further the present embodiment is illustrated, is powered on, motor starts running, and drives driving Axis drives swash plate 103 to operate, so that plunger 102 moves back and forth in plunger case 208, generates suction.Machine just starts to transport Air is first excluded when turning, the air in pump head 2 has thrust to the right to main valve 6, so that total valve core 601 and outlet conduit 211 oral areas have certain interval, and air is entered in gas bleeder valve 4 through this gap by the valve opening 405 that loses heart, and pass through the valve body 401 that loses heart Venthole discharge.When air is drained, water flow enters in gas bleeder valve 4, and with the raising of system hydraulic pressure, water flow is to steel ball 404 generate the effect of power, move upwards steel ball 404, contact with the second sealing ring 403, form sealing.When machine run, water Stream is entered in water inlet line 210 by water inlet 201, and the water feeding one-way valve 8 by being located in plunger case 208 enters plunger In cylinder 208, pumping under the continuous pressurization of water flow, water flow is entered by second pipe into water cavity 207, and passes through intake antrum The water one-way valve 9 that goes out in body 207 enters in outlet conduit 211.

When wherein, under hydraulic giant shooting state, water flow passes through main valve 6, is discharged by water outlet 202；Outlet conduit 211 Interior water flow is penetrated through by first through hole and pressure regulation valve chamber 206, by rotating adjusting pressuring knob 301, adjusts pressure regulator valve valve head 304 With the gap between valve seat 305, the circulation loop of water flow is formd, so that the part water flow in outlet conduit 211 passes through pressure regulation Gap between valve valve head 304 and valve seat 305, then water inlet 201 is flowed back to through first pipe.Change pressure regulator valve valve head 304 and valve Gap between seat 305 is completed the change of the flow to flow back to water flow in outlet conduit 211, is realized to water flow pressure Control.

When wherein, under hydraulic giant shooting state, the water in overflow valve 7 is flowed into through overflow valve opening A203 and overflow valve opening B212 Flowing pressure is identical, and overflow valve valve rod 702 ejects downwards under the elastic force effect of third elastic element 701, pushes sliding block 501 downward Movement touches microswitch 502, makes circuit in an ON state.

Wherein, when hydraulic giant closes under gun state, water outlet 201 is in close state, this makes in a flash 201 chamber of water outlet The hydraulic pressure that indoor hydraulic pressure is greater than in outlet conduit 211 pushes away main valve 6 under the action of water flow pressure difference to the right, total valve core 601 inclined-plane fits with 211 mouthfuls of outlet conduit, and sealing is realized under the action of the first sealing ring.Meanwhile being located at water outlet The indoor high pressure water flow of 201 chambers is flowed into overflow valve chamber 209 through overflow valve opening A, and the pressure of water flow is greater than third elasticity member The elastic force of part 701, so that overflow valve valve rod 702 moves upwards, overflow valve valve rod 702 contacts disconnection with sliding block 501, and fine motion is opened 502 rebounds are closed, circuit disconnects, system-down.

Wherein, when hydraulic giant closes under gun state, it is located at the indoor high pressure water flow of 201 chamber of water outlet and passes through pressure regulation valve pipeline 205 and valve hole 307 be flowed into 306 chamber of pressure regulation valve body, high pressure water flow is big to 303 thrust of pressure regulator valve core assembly In the elastic force of the first elastic element 302, move upwards pressure regulator valve core assembly 303, pressure regulator valve valve head 304 and valve seat 305 it Between gap become larger, converge the normal pressure water flow in low pressure water flow and first pipe in outlet conduit 211, so that outlet conduit The pressure of low pressure water flow in 211 is lower, positioned at the indoor high pressure water flow of 201 chamber of water outlet and is located in outlet conduit 211 The pressure difference of low pressure water flow becomes larger, and keeps the leakproofness of main valve 6 more stable.

The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art For art personnel, without deviating from the technical principle of the utility model, several improvements and modifications can also be made, these change It also should be regarded as the protection scope of the utility model into retouching.
