Abstract
The utility model relates to a spray gun of a sprayer, which is composed of a gun pipe, a spray head which is connected with the gun pipe, and a control valve which is arranged in the gun pipe. The control valve is provided with an inlet valve hole, a central water control valve hole and a drain valve hole in the gun pipe. A sealing gasket which is squeezed and fixed by a fixing thread sleeve is arranged on a water outlet of the water control valve hole, and a valve core and a spring are arranged in the fixing thread sleeve. A valve plate on the head of the valve core is matched with the sealing gasket, and a head valve cap of the valve core is matched with a handle crotch. A lever bracket is arranged on the wall of the gun pipe, and a handle is matched with the lever bracket. The spray gun can be operated by one hand, and has the advantages of convenient operation, no leakage and safety.
Description
The utility model relates to the sprayer accessory, particularly relates to the spray gun of sprayer, belongs to agricultural plant protection machinery.
Sprayer is to use the most general equipment for plant protection in the agricultural production, is connected jet pipe, spray gun and shower nozzle on the sprayer woven hose, be the critical piece that soup is sprayed to crops, and wherein spray gun is crucial operating mechanism.Existing sprayer spray gun is in the spray boom that connects handle rotary switch to be installed, similar in appearance to the Rotary Water tap, use the shortcoming of this switch to have: the one, need usually with two hand operateds, promptly one holds spray boom, and another hand operating switch handle is so use very inconvenient.The 2nd, the easy seepage of soup is polluted human body, clothing etc., and is caused waste.
The purpose of this utility model is the defective that overcomes prior art, provides a kind of use simple, is applicable to one-handed performance, and sealing is reliable, avoids the sprayer spray gun of leakage.
The technical scheme of the utility model sprayer spray gun is: by the shower nozzle of gun barrel and connection gun barrel, and be installed in control valve in the gun barrel etc. form, its described control valve is to be shaped on into water valve opening in the gun barrel, center control valve hole and draining valve opening, delivery port in water control valve hole, center is installed gasket seal, gasket seal is by fixedly the swivel nut extruding is fixing, spool and spring fixedly are installed in the swivel nut, the valve plate of spool head matches with gasket seal, the bonnet of spool other end matches with the handle prong, be shaped on lever dolly on the gun barrel wall, handle matches with lever dolly.
Sprayer spray gun of the present utility model is shaped on trip on its gun barrel, is equipped with the collar on the handle, and the collar matches with trip.
Sprayer spray gun of the present utility model is shaped on limiting plate on its handle, and limiting plate matches with the gun barrel outer wall.
Sprayer spray gun of the present utility model, the step of its gun barrel valve opening and fixing swivel nut become the sealing compressive plane to two of gasket seal periphery.
Sprayer spray gun of the present utility model is installed filter screen in its gun barrel.
The utility model discloses a kind of sprayer spray gun, compared with the prior art, have following characteristics: the one, press the spray gun handle, the prong of handle and sled fork are with the bonnet pull-up of spool, spring is compressed, and makes valve plate and gasket seal break away from compressing, and the water in control water hole, center extrudes through delivery port, spray and produce
Use very convenient, one-handed performance particularly.The 2nd, in the valve periphery of gasket seal by step and fixedly swivel nut crush seal, safety reliable for effect, soup can seepage, long service life.
Fig. 1 is the structural representation of the utility model sprayer spray gun.
Below in conjunction with Fig. 1 embodiment of the present utility model is done detailed explanation.
1, gun barrel; 2, filter screen; 3, water inlet valve opening; 4, center water control valve hole; 5, gasket seal; 6, draining valve opening; 7, sealing compressive plane; 8, shower nozzle connector; 9, shower nozzle; 10, sealing compressive plane; 11, spring; 12, fixing swivel nut; 13, handle prong; 14, handle sled fork; 15, bonnet; 16, spool; 17, valve plate; 18, lever dolly; 19, the collar; 20, trip; 21, handle; 22, limiting plate.
The utility model relates to the sprayer spray gun, and the gun barrel 1 of a straight rod type is arranged, and at the water inlet that the woven hose of gun barrel connects filter screen 2 can be installed, and the other end connects shower nozzles 9 through shower nozzle connector 8.Be equipped with control valve in gun barrel 1, system water inlet valve opening 3, water control valve hole, center 4 and draining valve opening 6 are installed gasket seal 5 in valve pocket, and gasket seal 5 forms two by step in fixing swivel nut 12 and the gun barrel and seals compressive planes 7,10.The water in water control valve hole, center 4 stops and ejection, by the compressing of 17 pairs of gasket seals 5 of valve plate of spool 16 whether determine that when spring 11 tightly pushed away gasket seal 5 with valve plate 17, water spray was closed; And hold to gun barrel 1 when handle 21, handle 21 is around lever dolly 18, and by the handle sled fork 14 that inserts the handle prong 13 under the bonnet 15 spool 16 upwards drawn, and makes spring 11 by compression, and the compressing power of 17 pairs of gasket seals 5 of valve plate reduces, the water spray beginning.For hand when the normal running is avoided for a long time the grip of handle 21 is enclosed within the collar on the handle 21 19 on gun barrel 1 trip 20 the soup continuous injection.For fear of making handle 21 transition compress gun barrel 1, on handle 21, be shaped on limiting plate 22.
