Description
Technical field
The utility model relates to viscous liquid spray appliance technical field, specifically a kind of adjustable spray gun.
Background technology
Viscous liquid such as glue, oil etc. are difficult to owing to having viscosity carry out spraying use, and the production efficiency in some industrialness production and application occasions just carries not high.If the shower nozzle using conventional water spray sprays, easily blocking, and do not reach spray effect, liquid throughput regulation plus shower nozzle during spraying is inconsistent, be easily caused race, emit, leakage etc., and operating inconvenience, the flusher being commercially applicable to viscous liquid at present is fewer, and using effect is undesirable.
Content of the invention
It is an object of the invention to for above-mentioned deficiency of the prior art, the present invention designs a kind of adjustable spray gun, can realize that gas-liquid is opened, mixed and be atomized simultaneously, and easy to operate, spraying effect is good.
The purpose of this practicality invention is achieved through the following technical solutions:
nullA kind of adjustable spray gun，Including gun、Nozzle、Nozzle needle、Connector and connection block，It is sequentially provided with cavity I in described gun、Cavity II and cavity III，And the glue inlet that is connected with cavity I and the air inlet being connected with cavity III，Described nozzle is provided with tapered spray orifice，Nozzle is installed on described cavity I external port，Described nozzle needle crosses in described cavity I、Cavity II and cavity III，The syringe needle of nozzle needle is taper cone，Match sealing with the tapered spray orifice of described nozzle，It is arranged with adjusting nut successively on described nozzle needle、Guide rod and spool，Described adjusting nut is connected with described guide rod through threaded，It is located in described cavity II，Adjusting nut side surface exposes，Described connector is fixed on described cavity III external port，It is provided with spring I between described spool and connector，Cavity III is separated into two chambers by spool，Respectively with air inlet and pass to the air flue of the tapered spray orifice of nozzle and connect，Described connection block is threaded connection and is connected with described connector，The afterbody of described nozzle needle is cased with nozzle needle cap，Nozzle needle cap is provided with spring II with being connected between block.When spray gun does not works, under the effect of spring I, valve core reset, it is pressed in gun, blocks the connection of air flue and air inlet, cut off circulation in air flue for the air；Under the effect of spring II, the tapered spray orifice of nozzle and the taper cone of nozzle needle match sealing, make the liquid of inlet not leak at nozzle bore.
In use, viscous liquid and gases at high pressure are connected to inlet and the air inlet of gun, guide rod can be promoted to move along nozzle needle by the adjusting nut moving or on rotation spray gun platform, overcome the elastic force of spring I to back down spool, so that the air flue in gun connects with air inlet.The spool simultaneously moving can overcome the resistance of spring II to promote nozzle needle cap to move together with nozzle needle, so that producing a very small-gap suture between nozzle and nozzle needle.So, the air-flow of the tapered spray orifice generation high speed at nozzle for the high-speed gas of air flue, sucks the liquid of inlet, forms open air-liquid blending space, produce preferable atomised jet effect, simultaneously by regulation adjusting nut, promote the movement of guide rod, spool and nozzle needle, the position of regulation spool, realize the switch of gas-liquid and the change of tolerance, different tolerance can be produced, produce different atomizing effects, meet different demands.
In further design, this adjustable spray gun also includes sprinkler cap and sprayer body, and described sprayer body is connected with described nozzle by described sprinkler cap, sprayer body center is formed with spray orifice, the tapered spray orifice of described nozzle extends in sprayer body spray orifice, and periphery leaves air gap, and this air gap connects with described air flue.Sprayer body is easily changed, and can get different mist types by runner spray orifice shapes different in sprayer body.
Installing for convenience and connecting viscous liquid and gases at high pressure, inlet and the air inlet of described gun are provided with hickey.
The present invention has a beneficial effect following outstanding:
The adjustable spray gun of the present invention, can be effectively adapted to spraying or the sprinkling of viscous liquid, drastically increase viscous liquid spray efficiency, can also be adjusted as required, produces different spraying dosage sizes and spraying atomizing effect, easy to operate.

Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment the invention will be further described:
nullSee Fig. 1、2、3，A kind of adjustable spray gun，Including sprinkler cap 1、Sprayer body 2、Nozzle 3、Nozzle needle 7、Gun 5、Connector 10 and connection block 13，It is sequentially provided with cavity I 17 in gun 5、Cavity II 18 and cavity III 19，And the glue inlet 14 that is connected with cavity I 17 and the air inlet 15 being connected with cavity III 19，Nozzle 3 is provided with tapered spray orifice，Nozzle 3 is installed on cavity I 17 external port，Sprayer body 2 is connected with nozzle 3 by sprinkler cap 1，Sprayer body 2 center is formed with spray orifice，The tapered spray orifice of nozzle 3 extends in sprayer body 2 spray orifice，Periphery leaves air gap，This air gap connects with air flue 16，The spray orifice of sprayer body and the tapered spray orifice of nozzle、The needle point of nozzle needle is concentric，Nozzle needle 7 crosses in cavity I 17、Cavity II 18 and cavity III 19，The syringe needle of nozzle needle 7 is taper cone，Match sealing with the tapered spray orifice of nozzle 3，It is arranged with adjusting nut 4 successively on nozzle needle 7、Guide rod 6 and spool 8，Adjusting nut 4 is threaded connection with guide rod 6，It is located in cavity II 18，Adjusting nut 4 side surface exposes，Connector 10 is fixed on cavity III 19 external port，It is provided with spring I 9 between spool 8 and connector 10，Cavity III 19 is separated into two chambers by spool 8，Respectively with air inlet 15 and pass to the air flue 16 of the tapered spray orifice of nozzle 3 and connect，Connection block 13 is threaded connection and is connected with connector 10，The afterbody of nozzle needle 7 is cased with nozzle needle cap 11，Nozzle needle cap 11 is provided with spring II 12 with being connected between block 13，The inlet 14 of gun 5 and air inlet 15 are provided with hickey.When spray gun does not works, under the effect of spring I9, spool 8 resets, and is pressed in gun 5, blocks the connection of air flue 16 and air inlet 15, cuts off circulation in air flue 16 for the air；Under the effect of spring II 12, the tapered spray orifice of nozzle 3 and the taper cone of nozzle needle 7 match sealing, make the liquid of inlet 14 not leak at nozzle 3 hole.
