Abstract
The present invention is a kind of novel ejection structure, and the model used of the most having installed mostly is concentration injection type structure.The injector of this kind of form has simple in construction, intensity high, but shortcoming is that injection ratio is relatively low, slightly inferior properties.The technical solution of the present invention is that ejection structure is divided into nozzle ring, rear seal ring and bump joint, and three kinds of parts, all by integrated machine add-on type, are then passed through being welded to form eductor.This arrangement enhances injection performance, avoid the problem that externally-hanging type nozzle strength is not enough, decrease weld seam quantity simultaneously, eliminate weak link, improve its global reliability.
Description
Technical field
The present invention relates to a kind of ejection structure.
Background technology
Injector is applied relatively broad in air circulation refrigeration system.Traditional multiinjector injector injection
Can still can, but due to structure and the problem of processing technique, during use, fault rate remains high, it is impossible to full
Foot reliability requirement, is the most gradually substituted by slightly inferior properties but the higher centralized injector of reliability.
The model used of the most having installed mostly is concentration injection type structure.The injector of this kind of form has structure
Simply, intensity high, but shortcoming is that injection ratio is relatively low, slightly inferior properties.
Summary of the invention
It is an object of the invention to provide a kind of novel ejection structure, this structure can be good at solving tradition ring
Shape ejection structure and the problem of centralized ejection structure degraded performance, can well make up tradition multiinjector simultaneously
The defect that ejection structure intensity, reliability are not enough.
A kind of annular multiinjector eductor structure for injector, it is characterised in that: include nozzle ring 1, after
Seal ring 2 and bump joint 3, nozzle ring 1 is the multiinjector structure of global formation, and nozzle quantity and arrangement can roots
Arrange in loop configuration according to performance need；Nozzle ring 1, rear seal ring 2 and bump joint 3 constitute airtight passage,
Three passes through integrated machine add-on type, is then passed through being welded to form, and provides runner for injection air.
Advantageous Effects: compared with tradition ejection structure, this novel ejection structure driving nozzle is by outer cantilever
Formula is improved to built-in, and processing technique is welded one by one by blast tube and is improved to overall machining, such as figure simultaneously
Shown in.This new construction not only increases injection performance, avoids the problem that externally-hanging type nozzle strength is not enough,
Decrease weld seam quantity simultaneously, eliminate weak link, improve its global reliability.
Accompanying drawing explanation
Fig. 1 is the structure composition schematic diagram of the present invention；
Fig. 2 is nozzle interior structural representation of the present invention；
Fig. 3 is tradition multiinjector ejection structure schematic diagram.
Detailed description of the invention
Below in conjunction with Figure of description, the present invention is described in further detail, refers to Figure of description 1-2, this
The bright annular multiinjector eductor structure for injector, including nozzle ring 1, rear seal ring 2 and bump joint
3, nozzle ring 1 is the multiinjector structure of global formation, and nozzle quantity and arrangement can be according to performance need in annulars
Arrange in structure；Nozzle ring 1, rear seal ring 2 and bump joint 3 constitute airtight passage, and three passes through integrated machine
Add-on type, is then passed through being welded to form, and provides runner for injection air.
