In above-mentioned a kind of giant, the intake tunnel on described handle is communicated with high-pressure water inlet passage and decompression aquaporin.
The present invention gives prominence to compared to existing technology and useful technique effect is:
1, in the present invention, hydraulic giant adopts ball-and-spring valve, valve rod is made to drive push rod to go to back down ball valve core by manpower cocking, wherein the chute at valve rod place communicates with air, namely make cocking comparatively light, secondly the water under high pressure in hydraulic giant is caused a termination of valve rod, cocking rear section water under high pressure helps applied thrust to valve rod, and the slip making valve rod follow-up is without the need to using too much manpower, especially when being full of water under high pressure in hydraulic giant, and the earth alleviates manipulation strength.
2, in the present invention control valve be arranged so that wear extent between part reduces, be also improve the service life of product and the stability of use further, be namely the reduction of use cost.
Accompanying drawing explanation
Fig. 1 is structure half sectional view of the present invention.
Fig. 2 is partial structurtes enlarged diagram in Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing, with specific embodiment, the invention will be further described, see Fig. 1-2:
A kind of giant, comprise playpipe 1, the high-pressure water inlet passage 11 being provided with control valve 3 in the body of a gun and be communicated with control valve 3 valve pocket and high pressure exhalant canal 12, high-pressure water inlet passage 11 is communicated with the intake tunnel 51 on handle 5, high pressure exhalant canal 12 is communicated with the exhalant canal 41 on spray boom 4, hingedly on the described body of a gun be fixed with trigger 6, the valve rod 30 of described control valve stretches out the upper end of body of a gun apical grafting at trigger, cocking makes valve rod promote spool thus controls being communicated with of high-pressure water inlet passage 11 and high pressure exhalant canal 12, the decompression water channel 7 that control valve 3 controls is provided with in the described body of a gun, decompression aquaporin two ends are connected with the intake tunnel 51 of handle with diversion mechanism and current are caused valve rod place respectively and reduce the thrust promoted needed for valve rod.
As preferably, described control valve is: the spool 314 valve seat 320 of the tail end setting of valve stem sleeve 32 being provided with ball-type, spool 314 uses spring top clamping on valve seat 320, push rod 321 apical grafting in front end and valve stem sleeve, the other end of spring holds out against on the spring base 310 that tail end is closed, the sidewall of spring base is provided with the through hole be communicated with high-pressure water inlet passage 11, the sidewall of valve stem sleeve 32 is provided with the through hole 8 be communicated with high pressure exhalant canal 12, spring base, sealing ring is respectively arranged with between valve stem sleeve and playpipe 1, sealing ring is provided with between valve stem sleeve and push rod 321.
As preferably, the front end expansion of described valve stem sleeve is formed with chute 323, the afterbody 301 of described valve rod is arranged in chute, the front portion 300 of valve rod is passed the body of a gun and stretches out apical grafting on the cushion block 60 of trigger, the front portion of valve rod and afterbody are tightly connected with the body of a gun and slide respectively, described valve rod offers axially extending bore 302 and chute is communicated with air.
