Abstract
The utility model relates to a spray nozzle of a turboexpander, which is arranged in fluid conveying equipment. The spray nozzle comprises a positioning disc, a positioning sleeve, a slide disc, blades and a cover plate, wherein the slide disc is arranged in a support frame, and is connected through a pull rod, the positioning sleeve is arranged between the positioning disc and the slide disc, the lower end surfaces of the slide disc and the positioning disc are provided with the blades, the lower end surfaces of the blades are provided with the cover plate, and the cover plate, the support frame and the positioning disc are sequentially and movably connected. The installation can be carried out according to a sequence from top to bottom during the installation of the spray nozzle of the turboexpander, i.e. firstly, the positioning disc is arranged on a turbo scroll casing, and then, the components are sequentially installed one by one according to a sequence of the positioning disc, the positioning sleeve, the slide disc, the pull rod, the blades, the support frame and the cover plate. Thereby, the installation of the spray nozzle is convenient and fast, and the operation has the labor saving effect.
Description
Technical field
The utility model relates to the turbine expansion machine nozzle in a kind of fluid transmission equipment.
Background technique
Turbo-expander is the core machinery of a kind of high speed rotating, cryogenic device, and it also must have good structure except will having good thermal performance, aerodynamic performance, mechanical property, technology capability.Under some big environment of working conditions change, accelerated the damage frequency of turbo-expander easily damaged parts, the frequency of maintenance of turbo-expander is increased, the corresponding maintenance expenses that also increases turbo-expander.
The turbine expansion machine nozzle is exactly an easily damaged parts wherein, opens and close frequency when big (when field working conditions changes greatly) at nozzle, and nozzle just is easy to go wrong, and so just need overhaul nozzle.Old-fashioned nozzle can disassemble, but installs but very inconvenient.From old-fashioned structure nozzle part sectioned view (Fig. 1) as seen, this structure is provided with stay rod pin, stay rod pin one end and slider disc interference fit, the other end and pull bar Spielpassung, and stay rod pin on the slider disc and the hole on the pull bar link up (alignment) be very the difficulty, in the turbine spiral case, have no idea to locate, pull bar must upwards pass the gap bridge ice chest simultaneously, so need claw the pearlife that is filled in the ice chest during dismounting nozzle, decompressor outer pipe, end cap, the diffusion chamber removes, also to fill out again after having overhauled, nozzle could be installed, time-consuming, bother very much.It can also be seen that from Fig. 1 slider disc and positioning disk are installed on the both ends of the surface up and down of blade respectively, make that the pin on the blade connects slider disc and positioning disk towards opposite both direction.So just this nozzle can not be installed piecemeal, but integral body being installed together earlier, both, before whole nozzle will be installed in earlier on the dividing plate, and then being installed on the turbine spiral case, also is very inconvenient.
The inconvenience of maintenance will cause the increase of engineering time, and at this moment be exactly money the engineering time of decompressor.
The model utility content
The purpose of this utility model is, provides a kind of quick and easy for installation, the turbine expansion machine nozzle of rapid operation.
The purpose of this utility model realizes by adopting following technological scheme:
A kind of turbine expansion machine nozzle, comprise positioning disk, setting sleeve, slider disc, blade and cover plate, slider disc is arranged in the support, connect by pull bar, setting sleeve is arranged between positioning disk and the slider disc, slider disc and positioning disk lower end surface are equipped with blade, and the blade lower end surface is provided with cover plate, and described cover plate, support and positioning disk flexibly connect successively.
Further, described slider disc and positioning disk lower end surface are equipped with blade by pin.
Further, described pin is all installed up.
Further, the movable pin that is installed on the slider disc lower end surface connects with hole on the pull bar.
Owing to adopted technique scheme, the beneficial effects of the utility model are:
1. the utility model has been cancelled the connection pin on the old-fashioned nozzle, slider disc and positioning disk are arranged at a side of nozzle, so just can install successively in order, promptly, earlier positioning disk is installed on the turbine spiral case, installs one by one by the order of positioning disk-setting sleeve-slider disc-pull bar-blade-support-cover plate again, need not open ice chest and take off sand again, so just make that the installation of nozzle is very light, convenient, rapid operation.
2. the movable pin on the slider disc can connect with pull bar fully, easily.For big decompressor, the threaded screw rod that can do several length replaces pull bar, and the size in hole is almost passable on the size of screw rod and the parts that are mounted, and so just has the strong point, will be laborsaving during installation.
Pin on positioning disk and the slider disc all up, so blade installation can not fall down on positioning disk and slider disc.
Description of drawings
Fig. 1 is old-fashioned structure turbine expansion machine nozzle partial sectional view.
Fig. 2 is the utility model turbine expansion machine nozzle partial sectional view.
Fig. 3 is the utility model turbine expansion machine nozzle scheme of installation.
Reference character: the 1st, slider disc, the 2nd, setting sleeve, the 3rd, positioning disk, the 4th, blade, the 5th, cover plate, the 6th, pull bar, the 7th, movable pin, the 8th, support, the 9th, pin, the 10th, stay rod pin.
Embodiment
As shown in Figure 2, a kind of turbine expansion machine nozzle comprises positioning disk 3, setting sleeve 2, slider disc 1, blade 4 and cover plate 5, and slider disc 3 is arranged in the support 8, connects by pull bar 6, and the movable pin 7 that is installed on slider disc 3 lower end surfaces connects with hole on the pull bar 6.Setting sleeve 2 is arranged between positioning disk 3 and the slider disc 1, and slider disc 1 and positioning disk 3 lower end surfaces are equipped with blade 4 by pin 9, and pin 9 is all installed up.Blade 4 lower end surfaces are provided with cover plate 5, and cover plate 5, support 8 and positioning disk 1 flexibly connect successively.
The utility model turbine expansion machine nozzle, cancelled the stay rod pin 10 in the old-fashioned nozzle, replace with movable pin 7, it is installed along as shown in Figure 3, during installation, earlier positioning disk 3 is installed on the turbine spiral case, install one by one by the order of positioning disk 3 → setting sleeve 2 → slider disc 1 → pull bar 6 → blade 4 → support 8 → cover plate 5 again, need not open ice chest and take off sand again, so just make that the installation of nozzle is very light, convenient, rapid operation.Because pin 9 is all up, so blade 4 is installed on positioning disk 3 and the slider disc 1, can not fall down, also be not influence to the installation of the cover plate 5 of back, one or two people just can install.So just make that the installation of nozzle is very light, convenient, rapid operation.
Because the movable pin 7 on the slider disc can connect with pull bar 6 fully, easily.For big decompressor, the threaded screw rod that can do several length replaces pull bar 6, and the size in hole is almost passable on the size of screw rod and the parts that are mounted, and so just has the strong point, will be laborsaving during installation.
