Abstract
The utility model discloses an included angle type jet device. The included angle type jet device comprises a jet device body, a working fluid passage pipe and a mixture fluid stabilizing cavity pipe. The jet device body is provided with a fluid mixing cavity and a fluid introducing passage, respective passages of the mixture fluid stabilizing cavity pipe, the working fluid passage pipe and the fluid introducing passage are communicated with the fluid mixing cavity, and an included angle is formed by the fluid introducing passage and the working fluid passage pipe. When the jet device is used, fluid quickly flows along a working fluid passage to quickly flow through a nozzle, a relative negative pressure is formed in the fluid mixing cavity to drive fluid in the fluid introducing passage to flow along the fluid introducing passage so as to enter the mixing cavity for mixing, and since directions of the two fluid flows form the included angle, the resistance is low, the fluids can be smoothly mixed to enter the mixture fluid stabilizing cavity, and efficiency in jet refrigeration can be promoted. The jet device is convenient to process and manufacture, low in production cost, less in joint links, steady and reliable in sealing and convenient for sealing and pipe connection due to the fact that all connection ports are in flaring structures.
Description
Technical field
The utility model belongs to ejector refrigeration technical equipment field, specifically a kind of injection apparatus that has angle form structure.
Background technology
The injection apparatus that generally uses is at present right angle form normally, spray exactly working fluid direction mutually vertical with injection introducing flow direction, the feature of this design is simple in structure, comparatively easily realize and spray the function of introducing fluid, but orthogonal with injection working fluid direction owing to spraying introducing fluid, in the time of must causing the two mixed flow, there are larger route change and flow resistance.Another injection apparatus is to spray working fluid direction to introduce flow direction and be parallel to each other even coaxially with spraying, and the feature of this design is that injection is smooth and easy, and efficiency is higher, but complicated structure, and production cost is higher.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the utility model provides a kind of injection apparatus of angle form.
The technical scheme that the utility model adopts is: a kind of injection apparatus of angle form, comprise injection apparatus main body, working fluid tube channel, fluid-mixing current stabilization lumen, sealing gland, sealing ring, friction top, described injection apparatus main body is provided with fluid hybrid chamber, also at least be provided with one and introduce fluid passage, described working fluid tube channel, introduce fluid passage and fluid-mixing current stabilization lumen channel connection fluid hybrid chamber separately, the angle that described introducing fluid passage and working fluid passage form is acute angle, described injection apparatus main body and sealing gland are bolted, described sealing gland and friction top are threaded connection, described injection apparatus main body, between sealing gland and working fluid tube channel three, be provided with sealing ring.
Preferably, described working fluid tube channel and fluid-mixing current stabilization lumen are arranged on coaxial position, and described working fluid tube channel arranges in angle of 45 degrees with introducing fluid passage.
Described fluid hybrid chamber front end is provided with fluid-mixing current stabilization entrance, and described fluid-mixing current stabilization entrance is arranged on the position that there is certain distance on passage joint right side.
Described working fluid passage front end is provided with nozzle, and the distance of described nozzle and fluid-mixing current stabilization entrance is by regulating the front and back position of working fluid tube channel to set.
Compared with prior art, the utility model beneficial effect is: spray working fluid mobile more smooth and easy with introducing fluid, drag reduction; This injection apparatus convenient processing and manufacture, production cost is low, and joint link is few, seals solid and reliablely, and three interfaces are all flared type structure, are convenient to sealing and take over.
Accompanying drawing explanation
Fig. 1 is the structure chart of the injection apparatus of a kind of angle form of the utility model.
In figure: 1. working fluid tube channel, 2. sealing gland, 3. introduces fluid passage, 4. fluid hybrid chamber, 5. fluid-mixing current stabilization lumen, 6. fluid-mixing current stabilization entrance, 7. injection apparatus main body, 8. nozzle, 9. sealing ring, 10. friction top.
Specific embodiment
In order more clearly to understand the technical solution of the utility model, below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of injection apparatus of angle form, comprise injection apparatus main body 7, working fluid tube channel 1, fluid-mixing current stabilization lumen 5, sealing gland 2, sealing ring 9, friction top 10, injection apparatus main body 7 is provided with fluid hybrid chamber 4 and introduces fluid passage 3, working fluid tube channel 1, introducing fluid passage 3 and fluid-mixing current stabilization lumen 5 channel connection fluid hybrid chamber 4 separately, working fluid tube channel 1 is with fluid-mixing current stabilization lumen 5 in coaxial position, and working fluid tube channel 1 and introducing fluid passage 3 shapes are in angle of 45 degrees.
Injection apparatus main body 7 and fluid-mixing current stabilization lumen 5 are by being welded to connect, guarantee to connect sealing, injection apparatus main body 7 is bolted with sealing gland 2, sealing gland 2 is threaded connection with friction top 10, friction top 10 is unscrewed, can before and after regulate the front and back position of working fluid tube channel 1.
Fluid hybrid chamber 4 front ends are provided with fluid-mixing current stabilization entrance 6, fluid-mixing current stabilization entrance 6 is arranged on the position that there is certain distance on passage joint right side, working fluid passage 1 front end is provided with nozzle 8, and the distance of nozzle 8 and fluid-mixing current stabilization entrance 6 is by regulating the front and back position of working fluid tube channel 1 to regulate.
Between injection apparatus main body 7, sealing gland 2 and working fluid tube channel 1 three, be provided with sealing ring 9, object is buffer fluid and extraneous passage, and limit fluid only flows in passage, avoids medium to leak and air enters injection apparatus.
Working fluid tube channel 1 entrance point, three interfaces of fluid-mixing current stabilization lumen 5 ports of export and introducing fluid passage 3 entrance point are all flared type structure, are convenient to sealing and take over.
During work, fluid is along working fluid passage Rapid Flow during through nozzle 8, owing to being subject to the aperture constraint of nozzle, working fluid is further accelerated and stably from nozzle, is sprayed, at fluid hybrid chamber, form a relative negative pressure, driving the fluid of introducing in fluid passage to enter hybrid chamber along introducing fluid passage mixes with it, because the direction of two fluids is mutually an acute angle, phase mutual interference is less, resistance is less, and working fluid Direction distortion is little, can very successfully be mixed into fluid-mixing current stabilization chamber, contribute to like this to promote the efficiency of ejector refrigeration.
The utility model is simple in structure, processing and easy to assembly, and production cost is low, and joint link is few, seals solid and reliable.During use, spray working fluid and introduce the smooth and easy mobile of fluid with injection, mix fully, it is high that efficiency is introduced in injection, greatly promoted the service behaviour of injection apparatus.
The above is only better embodiment of the present utility model, and the equivalence of doing according to structure, feature and principle described in the utility model patent claim therefore all changes or modifies, and is included in the utility model patent claim.
