Embodiment
Accompanying drawing being given for example only property explanation, it is impossible to be interpreted as the limitation to this patent;It is attached in order to more preferably illustrate the present embodiment Scheme some parts to have omission, zoom in or out, do not represent the size of actual product;To those skilled in the art, Some known features and its explanation may be omitted and will be understood by accompanying drawing.
In the description of the invention, it is necessary to which explanation, unless otherwise clearly defined and limited, term " installation ", " connects Connect " it should be interpreted broadly, for example, it may be being fixedly connected or being detachably connected, or it is integrally connected;It can be machine Tool connects or electrical connection;It can be joined directly together or be indirectly connected with by intermediary, it may be said that two The connection of element internal.For the ordinary skill in the art, with concrete condition above-mentioned term can be understood in the present invention Concrete meaning.Technical scheme is described further with reference to the accompanying drawings and examples.
As Figure 1-5, it is a kind of to rinse spray gun, including reducing agent entrance, air intake, rifle certainly for denitrification apparatus Bar, shower nozzle, the reducing agent entrance, air intake are arranged at barral of a gun side, and the shower nozzle is arranged at barral of a gun opposite side, its feature It is:Also include the high pressure air pipe being arranged on barral of a gun.
As the improvement of specific embodiment, check-valves is provided with the reducing agent entrance, air intake.
As the improvement of specific embodiment, the tracheal pressure of the high pressure air pipe is more than 0.6MPa.
As the improvement of specific embodiment, magnetic valve is provided with the high-pressure air pipe.
As the improvement of specific embodiment, sensor is provided with the high-pressure air pipe.
As the improvement of specific embodiment, the sensor is spring pressure sensor
As the improvement of specific embodiment, the spring pressure sensor include ceramic package, spring, stress sliding block, Elastic diaphragm, the ceramic package, spring, stress sliding block, elastic diaphragm are sequentially connected.
As the improvement of specific embodiment, the ceramic package, stress sliding block are insulating ceramics material.
As the improvement of specific embodiment, the ceramic package, stress sliding block have embedded hard contact.
As the improvement of specific embodiment, the reducing agent entrance is liquid reducer entrance, and the air intake is mist Change compressed air inlet.
There are two root entry pipelines on common double-current spray gun body:Mixed aerosol compressed air piping and liquid reducer pipe Road.The scheme that the invention solves technical problem is that one high pressure air pipe of increase, tracheal pressure are more than on spray gun 0.6MPa, a magnetic valve is housed between high-pressure air pipe and spray gun;Increase a spring pressure sensor on spray gun.
When being blocked in spray gun, spray gun interior conduit pressure rises, and pressure sensor opens pneumatic operated valve, utilizes high pressure pressure Contracting air is rinsed to spray gun inside;After blocking inside spray gun is rinsed well, internal pressure can be recovered to normal pressure, The spring reset of pressure sensor, pneumatic operated valve are closed, and high pressure air is cut off, and flushing process is completed.
There are two root entry pipelines on double-current spray gun body:Mixed aerosol compressed air piping and liquid reducer pipeline.Pipe Check-valves is equipped with road, prevents that air backflows when pressure-air from rinsing inside spray gun.Increase a high pressure compressed on spray gun Air hose, tracheal pressure are more than 0.6MPa, and a magnetic valve is housed between high-pressure air pipe and spray gun;Increase a bullet on spray gun Spring formula pressure sensor.When being blocked in spray gun, when spray gun interior conduit pressure rises to certain pressure, pressure sensor is opened Magnetic valve is opened, spray gun inside is rinsed using high pressure air;After blocking inside spray gun is rinsed well, internal pressure Power can be recovered to normal pressure, and the spring reset of pressure sensor, closed electromagnetic valve, high pressure air is cut off, flushed Journey is completed.Spring pressure switch is made up of insulating ceramics.Main composition is ceramic package, stress sliding block, spring, elastic membrane Piece.Ceramic package, stress sliding block are insulating ceramics material, wherein embedded hard contact, the hard contact of ceramic package with Magnetic valve is connected.Magnetic valve is opened during connection.Elastic diaphragm by gas-liquid mixture inside ceramic pressure switch internal and spray gun every From preventing ammoniacal liquor liquid corrosion hard contact.When retaining pressure rise occurs in spray gun, stress sliding block is promoted to move upwards, The hard contact that can overcome the resistance of spring good with ceramic package when reaching certain pressure is contacted, and at this moment magnetic valve is connected, high Pressure compressed air starts to rinse inside spray gun.Treat that spray gun interior flushing is clean, pressure recovers normal, and spring is by stress sliding block top Open, closed electromagnetic valve, high pressure air is closed.
In figure, position relationship being given for example only property explanation is described, it is impossible to be interpreted as the limitation to this patent;Obviously, this hair Bright above-described embodiment is only intended to clearly illustrate example of the present invention, and is not to embodiments of the present invention Limit.For those of ordinary skill in the field, other multi-forms can also be made on the basis of the above description Change or variation.There is no necessity and possibility to exhaust all the enbodiments.It is all the spirit and principles in the present invention it Interior made all any modification, equivalent and improvement etc., should be included within the protection domain of the claims in the present invention.
