Abstract
The utility model relates to a nozzle which is used for spraying paint. The utility model is characterized in that the internal part of a back seat is provided with a spray head, a front gas chamber wall, a back gas chamber wall, and an integrally combined component which is formed by the integral assembly of interference fit of spacing sleeves; a diameter an at a spout point of the front gas chamber wall is larger than a diameter b at the spout point of the spray head, and the front gas chamber wall is provided with a chamfering d. The utility model has the advantages of high precision of spraying gaps, uniform spraying, not attached walls, no reverse spraying, long use periods, alleviated labour intensity of workers, low cost, convenient assembly and disassembly, and good atomizing effects.
Description
The utility model relates to a kind of paint spray nozzle, particularly a kind of nozzle of cast iron pipe coating spraying usefulness of Thermomembrane method cast.
As Fig. 2, shown in Figure 3, there is following shortcoming in the nozzle of prior art: 1) spout gap instability, cause atomizing inhomogeneous.A
1With A
2Between the spout gap be the key point that guarantees deposition accuracies and atomizing effect be threaded because two parts adopt, cause radially instability, it is inhomogeneous to atomize, become flexible through operations involving high pressure between screw rod and the nut, exceed its normal clearance, also increased the difficulty of adjusting.2) A is passed through in air inlet
4Four spiral road grooves enter mixing chamber on the part, again through A
9The spout ejection is because air admission hole A
7Can only aim at A
4A notch (see figure 3) on the part end face causes gas mixed allocation inequality, directly influences atomizing effect.3) when strengthening mist flow, be easy to generate attached wall phenomenon, cause down spray, cause drip, destroy atomizing.
The purpose of this utility model provides a kind of nozzle even, no attached wall drip phenomenon of spraying.
The purpose of this utility model is achieved in that a kind of nozzle, comprises nut, back seat, it is characterized in that: be equipped with in back seat by shower nozzle, preceding air chamber wall, rear gas chamber's wall, spacer and adopt whole assembling of interference fit or holistic sub-assembly; Preceding air chamber wall has a chamfering d; The preceding diameter a of air chamber wall spout place is greater than shower nozzle spout place diameter b; A plurality of air admission holes are arranged on the spacer, form air chamber W between spacer and the rear gas chamber's wall, form air chamber Z between shower nozzle and the preceding air chamber wall.
The purpose of this utility model can also realize like this: six air admission holes are arranged on the spacer.
The utlity model has following advantage: because the assembling of nozzle employing integral body has spraying gap precision height, gas is through two sub-distribution, and spraying is even, not attached wall, spray, and life cycle is long, alleviates labor strength, and cost is low, easy accessibility, atomizing effect is good.
Elaborate below in conjunction with accompanying drawing:
Fig. 1 the utility model structural representation
Fig. 2 prior art nozzle arrangements figure
Fig. 3 is an A4 spare end view drawing among Fig. 2
The utility model is by original back seat 6, nut 3 and be designed to shower nozzle 1, preceding air chamber wall 2, rear gas chamber's wall 4 of interference fit close fit one, the sub-assembly of spacer 5 constitutes.Chamfering d and the preceding air chamber wall 2 diameter a of the spout place spout place diameter b greater than shower nozzle 1 is arranged on the preceding air chamber wall 2.6 air admission holes are arranged on the spacer 5.Form air chamber W between spacer 5 and the rear gas chamber's wall 4, form air chamber Z between shower nozzle 1 and the preceding air chamber wall 2.
The utility model has overcome the defective of prior art, emphatically its critical piece has been carried out processing and remodelling, has formed self good structure.
The screw thread that the first becomes between shower nozzle and the back seat is connected to whole assembling movingly, presses the interference type secure fit, thereby has guaranteed atomizing effect.
It two is at the distribution of air flow inequality, and problem that can not enlargement discharge has all designed a plurality of air admission holes, and formed two air chambers on rear gas chamber's wall, spacer, average to guarantee the secondary distribution air-flow.
It three is not produce down spray, attached wall phenomenon in the spraying process for making, the diameter a of air chamber wall spout place is greater than the spout place diameter b of shower nozzle before the design, an impulse force forward when being gushed out, air-flow and coating is arranged, in addition at chamfering d of the anterior design of preceding air chamber wall, it is sprayed in angular range, both made enlargement discharge also can not produce down spray, and caused drip, destroy atomizating phenomenon.
Claims (2)
1, a kind of nozzle comprises nut (3), back seat (6), it is characterized in that: be equipped with in back seat (6) by shower nozzle (1), preceding air chamber wall (2), rear gas chamber's wall (4), spacer (5) and adopt whole assembling of interference fit or holistic sub-assembly; Preceding air chamber wall (2) has a chamfering d; Preceding air chamber wall (2) the diameter a of spout place is greater than shower nozzle (1) spout place diameter b; Spacer has a plurality of air admission holes on (5), forms air chamber W between spacer (5) and the rear gas chamber's wall (4), forms air chamber Z between shower nozzle (1) and the preceding air chamber wall (2).
2, nozzle according to claim 1 is characterized in that: six air admission holes are arranged on the spacer (5).
