Abstract
The utility model relates to a novel spray head for concrete spraying devices, which comprises a spray head body and a spray head base. The external tube surface of the tail part of the spray head body is matched and inserted with the internal tube surface of the spray head base in a sliding way along the same axial line. Two ring-shaped seal rings are arranged in a circular ring slot on the external tube surface of the spray head body at the inserting and matching part of the spray head and the spray head base. A radial flange is arranged on the end port of the spray head base. A circle of radical protrusions are arranged on the external tube surface of the spray head body at the front end surface point of the flange. A ring-shaped platen is arranged on the front end point of the radical protrusions. Fastening screws are arranged on the ring-shaped platen and the flange. The spray head has the characteristics of reliable seal and convenient disassembly and assembly.
Description
The utility model relates to a kind of concrete sprayer, especially relates to a kind of concrete sprayer shower nozzle.
Mix applying of native supporting along with spraying, concrete sprayer is widely used in tunnel, culvert, subway, hydroelectric project, underground construction and colliery.The material that stirs enters the spraying machine conveying pipeline after being pressurizeed by spraying machine, arrives shower nozzle, finally adds small amount of moisture again and ejected by shower nozzle outside shower nozzle.The present shower nozzle (see figure 1) of using, constitute by sprayer body 1, nozzle boss 2, the afterbody of sprayer body is divided into light pipe face portion and this light pipe face screwed pipe face portion in front of rear, and the sealing ring 3 of two annulars is installed in two cannelures of the afterbody light face portion of sprayer body.The inner tube surface of nozzle boss 2 is divided into the threaded portion at seat mouthful place and the light pipe face portion of depths, is fastenedly connected by corresponding screw thread between sprayer body and the nozzle boss, and two sealing rings 3 at the light pipe face place by correspondence are sealed and matched.The intake chamber 4 that annular is arranged on the light face of the sprayer body between two sealing rings is worn along the direction of the circumference of intake chamber bottom surface and to be equipped with uniform inlet opening 5, and the position corresponding with entering groove worn and be equipped with water inlet 6 on sprayer body.Owing to be threaded in the sealing ring 3 above often damaging when changing sprayer body, cause and leak, and after cement enters in the screw thread, make the dismounting shower nozzle very inconvenient.
The purpose of this utility model is that a kind of sealing performance of design is reliable, is convenient to the concrete sprayer shower nozzle of dismounting shower nozzle.
For achieving the above object, the technical solution of the utility model has adopted a kind of concrete sprayer new type nozzle, comprise sprayer body and nozzle boss, coaxial line slip sleeve cooperates between the afterbody outer tube surface of sprayer body and the inner tube surface of nozzle boss, in the annular groove of the sprayer body outer tube surface of both sleeve mating parts, be equipped with two O-ring seals, flange is radially arranged on the nozzle boss port, the sprayer body outer tube surface at the front end face place of flange is provided with a circle radial protrusion, one annular platen is installed in the front end place of radial protrusion, on above-mentioned annular platen and the flange trip bolt is installed.
The centre of sprayer body afterbody two sealing rings has the annular intake chamber of a circle, is evenly equipped with 12 inlet openings along annular intake chamber bottom surface circumferencial direction, and water inlet is radially arranged on the nozzle boss of annular intake chamber correspondence position.
Owing to adopt direct coaxial line sleeve to cooperate, the drainage of having avoided the damage to sealing ring to bring helps spraying operation and improves spray-layer quality.In addition, directly sleeve cooperates and adopts platen fastening, also is convenient to the dismounting sprayer body, improves the efficiency of construction in the site operation process.
Below in conjunction with accompanying drawing the utility model is further explained and illustrates:
Fig. 1 is the structural representation of shower nozzle of the prior art;
Fig. 2 is a structural representation of the present utility model.
Among Fig. 2, shower nozzle of the present utility model is that the master constitutes by sprayer body 9 and nozzle boss 10, coaxial line slip sleeve cooperates between the afterbody outer tube surface of sprayer body and the inner tube surface of nozzle boss, the cannelure that two circumferencial directions are arranged on the sprayer body outer tube surface of both sleeve mating parts, two O-ring seals 11 are installed in two cannelures, on the outer tube surface of the sprayer body between two sealing rings, have the annular intake chamber 12 of circumferencial direction, circumferencial direction along annular intake chamber bottom surface evenly has 12 inlet openings 19, have the radially water inlet 13 that is interconnected with intake chamber with above-mentioned annular intake chamber 12 correspondence positions on nozzle boss, water inlet is welded with water inlet pipe 14 radially outward.The port of nozzle boss 10 is provided with flange 15 radially, the sprayer body outer tube surface at flange front end place is provided with the projection radially 16 of a circle and sprinkler body one, on this projection front end face, be adjacent to annular platen 17 is installed, tighten together by screw 18 between platen 17 and the flange 15.
After above-mentioned annular platen, annular protrusion and flange tightened together by screw 18, sprayer body can be secured together with nozzle boss.
