Abstract
The utility model relates to an air actuated polyurethane spray piston switch which essentially comprises a cylinder, a spray handle and a spray connecting rod. The cylinder is composed of a cylinder body, a cylinder back cover, a gas valve plug, a gas valve rod and an adjusting plug. The spray connecting rod is provided with an inlet groove, and the rear part of the spray connecting rod is provided with a spring. The utility model is characterized in that two valves of the front and back and two gas valves stems of the front and back are arranged in the cylinder of the air cylinder. A mid-blocking wall which is fixedly arranged in the middle of the cylinder through a spring lock ring is positioned between the two air valves. The back gas valve which can move to-and-fro goes across the mid-blocking wall and is connected with the front valve. Two air inlets of the front and back are arranged on the spray connecting rod. And the position of the two inlet groove aims at the back gas room of the two gas valves of the front and back when the spray connecting rod is triggered, and aims at the front gas room of the two gas valves of the front and back when the spray connecting rod is pushed back by the spring. The utility model has the advantages of material saving, energy saving and high efficiency.
Description
Technical field
The utility model belongs to a kind of building block of plastic-blasting instrument, and concrete is a kind of building block of polyurethane coating instrument, a kind of pneumatic means that is used for two kinds of feed liquids of polyurethane black and white are mixed simultaneously the polyurethane Switch of spray pistol of spraying.
Background technology
Polyurethane is very wide industrial raw material of a kind of purposes, usually is used for making the thermal-insulation coat pipe of pipeline etc., needs in the construction two kinds of polyurethane material of black and white are used simultaneously, and sprays while mixing.Usually use a kind of spray gun in this construction, i.e. the polyurethane spray gun.A kind of polyurethane spray gun is to promote a slide block by a kind of piston type cylinder, opens or closes the charging mouth of pipe of two kinds of liquid material of polyurethane black and white simultaneously.Usually need the injection of polyurethane to have bigger pressure in this construction, then the switch place of the charging mouth of pipe also has bigger pressure, so the slide block that needs to realize switch motion also will have the bigger power that is pushed, just the motive force to described piston type cylinder requires bigger.The device that present employed polyurethane spray gun promotes slide block is a piston type cylinder, just in cylinder the inside by one by an air valve and the piston that air valve stem is formed, piston is promoted back and forth movement in cylinder by gases at high pressure, thereby promote the slide block back and forth movement of connection, realize expecting the switch of the mouth of pipe.In order to realize making cylinder produce bigger motive force with less air pressure, thereby reduce the power and the working time of air compressor, dwindle the volume of spray gun, reduce the weight of spray gun, reach and save cost and using electricity wisely, alleviate the purpose of labor intensity of operating staff simultaneously, need to propose a kind of pneumatic means of new structure.
The utility model content
The purpose of this utility model is at the problems referred to above, proposes a kind of pneumatic means of polyurethane Switch of spray pistol of new structure, and this device is provided with two pistons in cylinder, improves the acting surface that enters the pressed gas in the cylinder, thereby improves the motive force of cylinder.
The purpose of this utility model is achieved through the following technical solutions:
A kind of pneumatic means of polyurethane Switch of spray pistol, mainly comprise cylinder, the gunslinging handle, the gunslinging connecting rod, described cylinder is mainly by cylinder barrel, the cylinder bonnet, gas valve core, air valve stem, the adjusting screw plug is formed, described gunslinging connecting rod is provided with air inlet duct, spring is equipped with in the rear end of gunslinging connecting rod, it is characterized in that, before being provided with in the cylinder barrel of described cylinder, latter two air valve and before, latter two air valve stem, be provided with a middle wall in the centre of two air valves, this centre wall is fixedly mounted on the centre of cylinder barrel by spring collar, wall was fixedlyed connected with preceding air valve in the middle of back air valve stem passed, and can come and go activity, before described gunslinging connecting rod is provided with, latter two air inlet duct, the position of these two air inlet ducts just in time is: before aiming at when the gunslinging connecting rod is pulled, the rear gas chamber of latter two air valve is before aiming at when the gunslinging connecting rod is pushed back by the spring of rear end, the preceding air chamber of latter two air valve; Be equipped with sealing ring between the outer of wall and forward and backward air valve and the cylinder barrel in the middle of described.
The utility model is owing to adopt the air cylinder structure of dual Piston, makes one times of the acting surface enlarged proximal that enters the pressed gas in the cylinder, so the motive force that the gas of same pressure produces cylinder has increased greatly.Like this when making the polyurethane material spray produce same pressure, the compressed-air actuated air pressure that the air feed cylinder is used then can be by a relatively large margin with low; The volume of spray gun also can dwindle, weight saving; Thereby labor intensity of operating personnel also can alleviate.Therefore, the utility model compared with prior art has the saving cost, and the conservation of power energy reduces labor intensity, the advantage of raising the efficiency.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
