Abstract

The utility model relates to a water-jet high-pressure gun, particularly a water-jet high-pressure gun which is used for the high-pressure cleanness. The utility model is composed of a mouth tightening nut, a nozzle, an injection tube, a valve body, a valve seat, a trigger, a pressure spring, a sliding sleeve, a handle, a shoulder rest, etc. The utility model is characterized in that a sliding valve, a sliding column and a sliding shaft are directly arranged on a valve clack; a flat trough of a double-face trigger is arranged on the sliding shaft and is positioned by a positioning pin; the pressure spring is installed on the sliding shaft of the front end of the trigger. The utility model has the advantages that simple structure is realized, the trigger action is flexible and reliable, the good sealing property is realized, and the valve clack can be prevented from generating the advancement phenomenon or the hysteresis phenomenon when the fluid jet is opened or closed by the valve clack.

Description

The water jet High Pressure Gun

The utility model relates to a kind of water jet High Pressure Gun, the water jet High Pressure Gun that particularly a kind of high-pressure wash is used.

Existing water jet High Pressure Gun, flap is made up of guiding valve, traveller and three parts of slide-bar, and synchronism is relatively poor when therefore causing unlatching or closing fluid jet, occurs leading or hysteresis and leakage problem easily.And its compression spring is installed in the trigger rear end, and when closing flap, it is big to be prone to the water attack reaction force, and is hard etc. when therefore spurring trigger.

The utility model provides a kind of trigger to be active in one's movements reliably for overcoming above-mentioned defective, guarantees that flap prevents leading or hysteresis, the water jet High Pressure Gun that the high-pressure wash that addresses the leakage concern is used when opening or closing fluid jet.

Solution of the present utility model is: directly be shaped on guiding valve on flap, traveller and slide-bar are provided with the flat groove of two-sided trigger at the rear portion of slide-bar, and with the alignment pin location, prevent flap leading or hysteresis and leakage problem when opening or closing fluid jet.Compression spring is installed on the slide-bar between trigger front end and the traveller step, the sensitivity of coming safety action.

Below in conjunction with drawings and Examples the utility model is done further statement.

Fig. 1 is a structure chart of the present utility model.

The utility model is made up of tight-lipped mother (1), nozzle (2), induction tunnel (3), valve seat (4), flap (5), valve body (6), compression spring (7), trigger (8), handle (9), buttstrap (10), alignment pin (11), sliding sleeve (12), seat cushion (13).Conical nozzle is packed in the tight-lipped mother, tight-lipped mother again with induction tunnel body left end thread connection, therebetween is with sealing gasket, simultaneously, press from both sides with the sealing gasket thread connection equally in the right part of induction tunnel and the left part of valve body, and compress valve seat, guarantee valve seat assembling and positioning and sealing.The valve body inlet is processed into the fluid operating chamber with flap, and the guiding valve of flap front end is a cone, and when quitting work, under the effect of compression spring, cone stretches into valve support chamber about 1/2, is used for high-pressure fluid is dammed.On the traveller at flap middle part, be shaped on two upper grooves and put into O type circle and be used for preventing that the right side high-pressure fluid from leaking, on the slide-bar of flap rearward end, be shaped on the flat groove of two-sided trigger, and, sliding sleeve be housed, to guarantee the concentricity of flap motion in handle end with the alignment pin location.For easy to operate, be provided with buttstrap and seat cushion in handle end, high-elastic plastics are housed on the buttstrap.

The utility model is compared with original technology, have simple in structure, trigger action spirit Quick reliable, good airproof performance, it is leading when opening or closing fluid jet to have overcome flap Or hysteresis.

Claims

1, a kind of water jet High Pressure Gun, mainly formed by tight-lipped mother, nozzle, induction tunnel, valve seat, valve body, compression spring, trigger, alignment pin, sliding sleeve, buttstrap, seat cushion, it is characterized in that: on flap, directly be shaped on guiding valve, traveller and slide-bar, on the slide-bar of flap right part, be shaped on the flat groove of two-sided trigger, and with alignment pin location, compression spring is installed on the slide-bar of right step of traveller and trigger front end.
