Description
Technical field
This utility model relates to a kind of combination type nozzle of sand spraying machine, belongs to nozzle of sand spraying machine field.
Background technology
Sandblasting machine is employing compression air is power, and with abrasive material for medium, compression air flows through formation negative pressure in spray gun, abrasive material injection to nozzle at high speeds is ejected into and need to be processed surface of the work, to hold as fulcrum, workpiece is sprayed, the surface of workpiece can be made to produce the equipment of favourable change. Wherein nozzle of sand spraying machine is important parts, and it is directly connected to quality and the efficiency of sandblasting processing. Nozzle of sand spraying machine inner chamber is generally divided into contraction section and diffuser. At present, the nozzle of sand spraying machine on market is mostly integral moulded nozzle, and the contraction section of nozzle and diffuser are one. But in normal operation process, contraction section to suffer the impulsive force that high-speed Medium is very big, diffuser then will not, so contraction section loss is generally big than diffuser, therefore once contraction section damage, it is necessary to changing whole nozzle, cost is very high. Additionally, various types of nozzles on market, although have a great difference in diffuser part, but contraction section is but almost completely general, so the main mouth of multiple different diffusers can share the importing mouth of identical contraction section, This further reduces the cost changing different diffuser nozzles.
Utility model content
Technical problem to be solved in the utility model is in that: provides a kind of combination type nozzle of sand spraying machine, it solves nozzle short for service life, the problem that replacement cost is high.
Technical problem to be solved in the utility model takes techniques below scheme to realize:
A kind of combination type nozzle of sand spraying machine, it includes importing mouth, main mouth, sealing member, described importing mouth arrival end is provided with installation screw thread, importing mouth inner chamber be divided into contraction section and connect chamber, described connection cavity wall is provided with connection female thread, and described main mouth one end is provided with connecting portion, connecting portion is provided with connection external screw thread, connecting portion puts sealing member and inserts in connection chamber, is meshed with being connected external screw thread by connecting female thread, will import mouth and seal fixing with main mouth.
As preferred embodiment, described main mouth is double; two main mouths of Wen.
As preferred embodiment, described main mouth is the main mouth of angle.
As preferred embodiment, described sealing member is rubber seal.
The beneficial effects of the utility model are: the contraction section of nozzle and diffuser are respectively prepared importing mouth and main mouth, extend the service life of main mouth, reduce the replacement cost of nozzle; Import mouth can from the main mouth of different diffusers with the use of, reduce nozzle purchase cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is double; two main mouth schematic diagrams of Wen;
Fig. 3 is the main mouth schematic diagram of angle.
In figure: import mouth 1, main mouth 2, sealing member 3, screw thread 11, contraction section 12 are installed, connect chamber 13, connect female thread 14, connecting portion 21, connect external screw thread 22, the main mouth 4 of double; two Wens, the main mouth 5 of angle.
Detailed description of the invention
In order to technological means of the present utility model, creation characteristic, reach purpose and effect and be easy to understand, below in conjunction with being specifically illustrating, this utility model is expanded on further.
As shown in Figure 1-Figure 3, a kind of combination type nozzle of sand spraying machine, it includes importing mouth 1, main mouth 2, sealing member 3, import mouth 1 arrival end and be provided with installation screw thread 11, import mouth 1 inner chamber be divided into contraction section 12 and connect chamber 13, connect chamber 13 inwall and be provided with connection female thread 14, main mouth 2 one end is provided with connecting portion 21, connecting portion 21 is provided with connection external screw thread 22, connecting portion 21 puts sealing member 3 and inserts in connection chamber 13, it is meshed with being connected external screw thread 22 by connecting female thread 14, importing mouth 1 and main mouth 2 are sealed fixing. Main mouth 2 can be double; two main mouths 4 of Wen. Main mouth 2 can be the main mouth 5 of angle. Sealing member 3 is rubber seal.
The contraction section 12 of nozzle is respectively prepared importing mouth 1 and main mouth 2 with diffuser, extends the service life of main mouth 2, reduce the replacement cost of nozzle; Import mouth 1 can from the main mouth 2 of different diffusers with the use of, reduce nozzle purchase cost. Sealing member 3 plays and will import the effect that mouth 1 seals with main mouth 2.
Main mouth 2 is detachable, is replaced with the various main mouth 2 having unified interface. Such as, the main mouth of double; two Wens 4: the main mouth 4 of double; two Wens has air inlet, owing to the effect of high velocity air produces a negative pressure, draws ambient air in nozzle; Cause that the air capacity of ejection is more than the air capacity sucked. The sandblasting area of double; two Wens main mouth 4 sandblasting area ratio Venturi nozzle reaches 35%, and the muzzle velocity of blast media decreases. This kind of nozzle is frequently used for the surface treatment of large area moderate strength. The main mouth 5 of angle: make the direction of motion of abrasive material change, can be used to the position of other more difficult cleanings such as the inner surface clearing up the truss of the steel construction such as bridge, steel tower, the back side of flange, firm pipe. The angle of the centrage in the hole of the main mouth 5 of angle and the axis of nozzle has 45 degree/90 degree/135 degree, it is possible to meet the needs of different construction sites, the process of difformity workpiece.
Of the present utility model ultimate principle and principal character and of the present utility model advantage have more than been shown and described. Skilled person will appreciate that of the industry; this utility model is not restricted to the described embodiments; under the premise without departing from this utility model spirit and scope, this utility model also has various changes and modifications, and these changes and improvements both fall within the scope of claimed this utility model. This utility model claims scope and is defined by appending claims and equivalent thereof.
