Abstract
The invention discloses an adjustable spraying gun. The adjustable spraying gun comprises a spraying gun base, a nozzle, a spraying needle, a connecting body and a connecting cap. An adjustment nut, a guide rod and a valve element are sequentially arranged on the spraying needle in a sleeving mode. The adjustment nut is connected with the guide rod through threads. The guide rod can be pushed to move along the spraying needle by moving or rotating the adjustment nut, the valve element is ejected to be open, and an air way in the spraying gun base is communicated with an air inlet accordingly; meanwhile, the moving valve element can push a spraying needle cap and the spraying needle to jointly move, and therefore a quite small gap is formed between the nozzle and the spraying needle. High-speed air in the air way generates high-speed air flow at a conical spraying hole of the nozzle, liquid of a liquid inlet is sucked, open air-liquid mixing space is formed, and the ideal atomization spraying effect is generated. The adjustable spraying gun can be effectively suitable for spraying or sprinkling or viscous liquid, the viscous liquid spraying efficiency is greatly improved, adjustment can be further carried out according to requirements to generate different spraying amounts and different spraying atomization effects, and operation is convenient.
Description
Technical field
The present invention relates to viscous liquid spray appliance technical field, is a kind of adjustable spray gun specifically.
Background technology
Viscous liquid uses as glue, wet goods not easily carry out sprinkling owing to having viscosity, just carries not high in the production efficiency of some industrialness production and application occasions.If use the shower nozzle of conventional water spray to spray, easy blocking, and do not reach spray effect, add that the liquid throughput of shower nozzle during spraying regulates inconsistent, easily cause running, emit, leakage etc., and operation inconvenience, the flusher being commercially applicable to viscous liquid is at present fewer, and result of use is undesirable.
Summary of the invention
The object of the invention is for above-mentioned deficiency of the prior art, the present invention designs a kind of adjustable spray gun, and can realize gas-liquid simultaneously and open, mix and be atomized, easy to operate, spraying effect is good.
The object of this practicality invention is achieved through the following technical solutions:
A kind of adjustable spray gun, comprise gun, nozzle, nozzle needle, connector be connected block, cavity I is provided with successively in described gun, cavity II and cavity III, and the glue inlet to be connected with cavity I and the air inlet be 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 point, match with the tapered spray orifice of described nozzle and seal, described nozzle needle is arranged with adjusting nut successively, guide rod and spool, described adjusting nut is connected with described guide rod through threaded, be located in described cavity II, adjusting nut side surface exposes, described connector is fixed on described cavity III external port, spring I is provided with between described spool and connector, cavity III is separated into two chambers by spool, be communicated with air inlet and the air flue that passes to the tapered spray orifice of nozzle respectively, described connection block is threaded connection and is connected with described connector, the afterbody cover of described nozzle needle has nozzle needle cap, nozzle needle cap be connected block a shot between be provided with spring II.When spray gun does not work, under the effect of spring I, valve core reset, is pressed in gun, blocks being communicated with of air flue and air inlet, cuts off the circulation of air in air flue; Under the effect of spring II, the taper cone point of the tapered spray orifice of nozzle and nozzle needle matches sealing, and the liquid of inlet is not leaked at nozzle bore place.
In use, viscous liquid and gases at high pressure are connected to inlet and the air inlet of gun, can promote guide rod by the adjusting nut on mobile or rotation spray gun platform to move along nozzle needle, the elastic force overcoming spring I backs down spool, thus the air flue in gun is communicated with air inlet.The resistance that the spool of movement simultaneously can overcome spring II promotes nozzle needle cap and moves together with nozzle needle, thus makes to produce a very small―gap suture between nozzle and nozzle needle.Like this, the high-speed gas of air flue produces air-flow at a high speed at the tapered spray orifice of nozzle, sucks the liquid of inlet, forms gas, the liquid blending space opened wide, produce desirable atomised jet effect, simultaneously by regulating adjusting nut, promote the movement of guide rod, spool and nozzle needle, the position of regulating spool, realize the switch of gas-liquid and the change of tolerance, different tolerance can be produced, produce different atomizing effects, meet the different needs.
In further design, this adjustable spray gun also comprises sprinkler cap and sprayer body, described sprayer body is connected with described nozzle by described sprinkler cap, sprayer body center is shaped with spray orifice, the tapered spray orifice of described nozzle extends in sprayer body spray orifice, periphery leaves air gap, and this air gap is communicated with described air flue.Sprayer body is easily changed, and can obtain different mist types by runner spray orifice shapes different in sprayer body.
Conveniently install and connect viscous liquid and gases at high pressure, inlet and the air inlet of described gun are provided with hickey.
The present invention has following outstanding beneficial effect:
Adjustable spray gun of the present invention, effectively can be applicable to spraying or the sprinkling of viscous liquid, drastically increase viscous liquid spray efficiency, can also regulate as required, produces different spraying dosage sizes and spraying atomizing effect, easy to operate.
