Abstract
The utility model relates to a pump head assembly of a high pressure water cleaning machine, which is composed of a pump head, a high pressure cylinder, and valves, wherein the T-shaped high pressure cylinder is arranged on the pump head, the high pressure cylinder is provided with a plunger sleeve, a plunger, a sealing ring, valves, a high pressure deflection tube, a high pressure chamber, a liquid-in valve, a tapping valve, a liquid inlet pipe, a liquid inlet hole, etc. Because inlet and tapping valves are not arranged in the pump head, the pump head can only have the function of a liquid inlet and outlet channel. The high pressure cylinder bears the alternating stress of frequently varying high pressure through the high pressure deflection tube, reduces breakage caused by fatigue, and extends service life, and meanwhile, valves are installed on one end of the high pressure cylinder and are convenient to disassemble.
Description
The utility model relates to a kind of cleaning machine, particularly high pressure washer pump head assembly.
At present, commercially available high pressure washer is made up of mutually perpendicular high pressure cylinder and combination valve group two parts of being installed in the pump head with the pump head parts, the maximum stress place of concentrating is just on the intersection that the two vertical intersection forms in the pressure chamber, along with the pressure alternation of water is frequent, stress raiser is cracked, causing pump head often therefore to burst apart scraps, have a strong impact on service life, simultaneously, the pump head maintenance is inconvenient, and the maintenance cost height, and the user would rather scrap by complete machine, also be reluctant to change pump head separately, thereby cause bigger waste.
The purpose of this utility model is to provide unstressed concentrating in a kind of pressure chamber, long service life, high pressure washer pump head assembly easy to loading and unloading.
The technical solution of the utility model is achieved in that high pressure washer pump head assembly, form by pump head, high pressure cylinder, valve group three parts, "T"-shaped high pressure cylinder is housed, in the plunger bushing of high pressure cylinder on the pump head, plunger is housed, between plunger and the plunger bushing sealing ring is arranged; The other end at plunger bushing is equipped with the valve group, the valve group switching centre has a high pressure guide pipe, valve group and plunger form high pressure chest near the place, the high pressure guide pipe is equipped with spring capping and feed liquor valve in an end of high pressure chest, between feed liquor valve and the spring capping spring is arranged, the inlet opening that is retrained by the feed liquor valve is arranged on the valve group; The other end of high pressure guide pipe is in the cavity of valve group, and tapping valve is housed; Cavity communicates with the discharging tube of high pressure cylinder and pump head, and discharging tube has leakage fluid dram on pump head, and the inlet opening of valve group is communicated with the feed tube of high pressure cylinder and pump head, on the feed tube of pump head inlet is arranged; High pressure cylinder stub end envelope has gland.
The utility model is not owing to be installed into the tapping valve group in the pump head, pump head only plays feed pathway and apocenosis passage, adopt the high pressure guide pipe to bear the high-voltage alternating stress of frequent variations in the high pressure cylinder, reduced the destruction that pump head produces because of fatigue, prolong its service life, simultaneously, the valve group is installed in high pressure cylinder one end, open gland and just can take out whole valve group, demolition and maintenance are very convenient.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a cutaway view of the present utility model.
With reference to accompanying drawing, the utility model is made up of pump head 3, high pressure cylinder 8, valve group 5 three parts, "T"-shaped high pressure cylinder 8 with screw fixings on the pump head 3, in the plunger bushing 13 of high pressure cylinder 8, plunger 1 is housed, and the tired folded sealing ring 2 of multilayer is arranged between plunger 1 and the plunger bushing 13.The other end at plunger bushing 13 is equipped with valve group 5, there is the superior alloy steel high pressure guide pipe 16 of a surface through roll extrusion or anticorrosive nitrogenize intensive treatment at valve group 5 centers, valve group 5 forms high pressure chest 10 with plunger 1 near the place, high pressure guide pipe 16 is equipped with spring capping 14 and feed liquor valve 9 at an end of high pressure chest 10, feed liquor valve 9 can be that cone valve also can be a flap type, between feed liquor valve 9 and the spring capping 14 spring 12 is arranged, a plurality of inlet openings 15 uniform on the valve group 5 are being blocked up by feed liquor valve 9, control its switching.The other end of high pressure guide pipe 16 is in the cavity 7 of valve group 5, and tapping valve 17 is housed, and tapping valve 17 adopts cone valve.Cavity 7 communicates with the discharging tube of high pressure cylinder 8, and vertical the communicating of discharging tube of the discharging tube of pump head 3 and high pressure cylinder 8 forms discharging tube 18 jointly, and the end of discharging tube 18 is leakage fluid drams 4.The inlet opening 15 of valve group 5 is communicated with the feed tube of high pressure cylinder 8 and forms annular lead channel 20 on the valve group, and vertical the communicating of feed tube of the feed tube of pump head 3 and high pressure cylinder 8 forms feed tube 19 jointly.High pressure cylinder 8 stub ends are being screwed gland 6.During cleaning machine work, when bent axle drives plunger 1 when left moves, produce negative pressure in the high pressure chest 10, tapping valve 17 on high pressure guide pipe 16 terminations in the valve group 5 is closed, feed liquor valve 9 is opened, low-pressure water is by the 11 process feed tubes 19 of the inlet on the pump head 3, opening feed liquor valve 9 by inlet opening 15 again enters and is full of high pressure chest 10, when plunger 1 when right is moved, the spool of feed liquor valve 9 is closed, water under high pressure is opened tapping valve 17 by high pressure guide pipe 16, and process cavity 7 also enters discharging tube 18, discharges by discharging tube 18 to leakage fluid dram 4 places in the pump head 3.
