Background technique
Ejector is the disorderly diffusion utilizing jet, and the two fluids of different pressures is mixed mutually, and causes fluid machinery and the mix reaction equipment of energy interchange.Ejector forms primarily of main jet, receiving chamber, mixing chamber and explosion chamber, the fluid that before inletting device, pressure is higher is called working fluid, working fluid flows out from nozzle with very high speed, enter receiving chamber, due to the turbulent diffusion of jet, entrainment the fluid of surrounding and the exchange of momentum occurs, being sucked away the lower fluid of pressure driving fluid.
In ejector, regulating spool is operationally by moving back and forth, and regulate the flow entering fluid, therefore must ensure that the coaxality of the assembling of each parts is high, the error of coaxality is from two aspects, and one is machining error, and two is assembly errors.
There is following defect in existing ejector: the first, connects defective tightness between each parts of existing ejector; Second, existing ejector generally by manual assembly, easily occurs due to the problem that the gap of bolt hole causes coaxiality error to strengthen, and resistance suffered when the regulating spool of ejector is worked increases, the working efficiency of ejector work is reduced, and working stability is low.
Model utility content
The purpose of this utility model is to provide a kind of high stability ejector, mainly solves the connection existed in prior art working efficiency that is not tight and that cause because coaxality is not high and reduces, the problem that working stability is low.
To achieve these goals, the technical solution adopted in the utility model is as follows:
A kind of high stability ejector, comprise cylinder block, main valve shell, output shell and explosion chamber, be connected with the entry end of described main valve shell by convex flange bolt bottom described cylinder block, the outlet end of described main valve shell is connected with the entry end of described output shell by convex flange bolt, the outlet end of described output shell is by being connected by the entry end of convex flange bolt with described explosion chamber, all described convex flange bolts are equipped with seam device, described seam device comprises seam bar and rabbet seat, the center of described rabbet seat is provided with groove, described groove matches with described seam bar, the inwall of described groove is evenly provided with multiple clamping device, described clamping device comprises cylinder and spring, one end of described spring is connected with the inwall of described rabbet seat, the other end of described spring is connected with one end of described cylinder, described cylinder is slidably connected with described groove inner wall, the compressible length of described spring is less than the height of described cylinder, one end that described cylinder is positioned at described groove is the concave surface matched with described seam bar, cylinder is used for determining that seam bar enters into the position of rabbet seat when seam bar enters groove, and after seam bar enters groove completely, cylinder under the effect of spring force, can compress seam bar, makes seam bar and rabbet seat coordinate tightr.
In said structure, it is tightr that convex flange bolt makes each several part connect, and seam device makes the utility model can eliminate the error of artificially assembling and bringing, the coaxality of strict guarantee ejector, makes the operation that the utility model energy is steady in a long-term.
Described seam bar and described groove are taper; Seam bar and rabbet seat are more easily coordinated.
The bottom of described seam bar is provided with hemisphere; The bottom of described groove is provided with the sucker matched with described hemisphere; Hemisphere is used for coordinating with sucker, and it is tightr that hemisphere and sucker cooperation make seam bar be connected with rabbet seat, can not rotate.
Described hemisphere and described sucker are made by rubber.
Compared with prior art, the utility model has following beneficial effect:
(1) in the utility model convex surface flange bolt have multiple connecting screw hole make each several part connect tightr, seam device makes the utility model can eliminate the error of artificially assembling and bringing, strict guarantee coaxality of the present utility model, improve working efficiency of the present utility model, and operation that can be steady in a long-term.
(2) in the utility model, cylinder is used for determining that seam bar enters into the position of rabbet seat when seam bar enters groove, after seam bar enters groove completely, cylinder can under the effect of spring force, compress seam bar, seam bar and rabbet seat are coordinated tightr, improve stability of the present utility model.
(3) in the utility model, hemisphere is used for coordinating with sucker, and it is tightr that hemisphere and sucker cooperation make seam bar be connected with rabbet seat, can not rotate, make utility model works more stable.
