Abstract
The utility model relates to a nozzle structure of a turbo expander, which comprises an annular nozzle main body and a pull rod mechanism for adjusting the opening and the closing of the annular nozzle main body, wherein the nozzle main body comprises a cover plate, a rotating disc and an end cover; the pull rod mechanism is connected with the rotating disc in the radial direction; the single surface of the end cover is fixed to the cover plate, and the rotating disc and a nozzle blade are arranged between the cover plate and the end cover in sequence; the nozzle blade is connected with the end cover through a fixed pin, and the rotating disc is pressed on the nozzle blade; a cylindrical helical spring is also arranged between the cover plate and the rotating disc, so as to enable the rotating disc to tightly press the nozzle blade. In such a way, by adopting the nozzle structure, the rotating disc can be enabled to be in tight contact with the nozzle blade, so that the zero clearance axial fit is realized; meanwhile, through the connecting way of the pull rod mechanism of the nozzle structure, great convenience is brought to the disassembly and the assembly of the mechanism, so that the efficiency of the whole machine is greatly improved, and the energy-saving and effect improving purposes are achieved.
Description
Technical field
The utility model relates to mechanical field, particularly relates to a kind of spray nozzle of turboexpander structure.
Background technique
The Kong Fen producer of China develops into present four, Wu Shijia by eight sufficient tripartite confrontations of the eighties in last century, has really entered the epoch of Warring states' disputes.Along with market competition is more and more fierce, the performance of product more and more becomes a key index, as the supporting unit-turbo-expander of the key in air separation plant, also must adapt to the requirement of complete sets of equipment, not only requiring to process tolerance can regulate, and efficiency is higher, mounting or dismounting also must be more convenient.All these requirements, have all proposed new test to the design of decompressor.In order to improve efficiency and the combination property of decompressor, we have made initiative innovative development to the structure of the critical component-adjustable nozzle of decompressor.
In turbo-expander, the critical piece that affects efficiency has nozzle and expansion wheel, wherein nozzle has the greatest impact, nozzle velocity coefficient improves one percentage point, and the efficiency of whole decompressor also almost improves a percentage, and turbo-expander is adjust flux, substantially all adopt adjustable nozzle structure, but common adjustable nozzle structure dismounting is difficult, and working efficiency is low, is unfavorable for technological innovation.
Model utility content
The technical problem that the utility model mainly solves is to provide a kind of spray nozzle of turboexpander structure, and it is reasonable in design, simple in structure, has solved efficiency and the dismounting problem of spray nozzle of turboexpander structure.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is to provide a kind of spray nozzle of turboexpander structure, and it comprises: the nozzle body of annular and for regulating the drag link mechanism of nozzle body folding; This nozzle body comprises: cover plate, rolling disc and end cap, and the cylinder lever connecting rod mechanism that makes progress in the footpath of rolling disc; Described end cap one side is fixing on the cover board, also establishes successively rolling disc and nozzle vane between cover plate and end cap; Described nozzle vane is connected on end cap by fixing pin, and rolling disc covers on nozzle vane; Between cover plate and rolling disc, being also provided with cylindrically coiled spring can make rolling disc compress nozzle vane.
Preferably, between drag link mechanism and rolling disc, adopt waist shaped hole straight-bar to be connected, and the locating stud on rolling disc adopt the conical structure of tape guide location.
The beneficial effects of the utility model are: a kind of spray nozzle of turboexpander structure is provided, and this nozzle arrangements can make rolling disc and nozzle vane close contact, has realized zero clearance and has axially coordinated; The Placement of its drag link mechanism brings great convenience to the dismounting of mechanism simultaneously, thereby the efficiency of entire machine is greatly improved, and has reached the object of energy efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of spray nozzle of turboexpander structure of the utility model;
Fig. 2 is the structure cut-away view of nozzle body side-looking;
Fig. 3 is the partial sectional view that nozzle body master looks;
Fig. 4 is the local enlarged diagram of cylindrically coiled spring;
In accompanying drawing, the mark of each parts is as follows: 1, nozzle body; 2, drag link mechanism; 3, cover plate; 4, rolling disc; 5, end cap; 6, nozzle vane; 7, fixing pin; 8, cylindrically coiled spring; 9, waist shaped hole straight-bar connects; 10, conical structure.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.
Refer to accompanying drawing 1 to 4, the utility model is embodiment comprise:
A spray nozzle of turboexpander structure, it comprises: annular nozzle body and for regulating the drag link mechanism of nozzle body folding; This nozzle body comprises: cover plate, rolling disc and end cap, and the cylinder lever connecting rod mechanism that makes progress in the footpath of rolling disc; Described end cap one side is fixing on the cover board, so just possible many leakage points is reduced to a place, and by the weight saving of cover plate about half, because being brass, makes by cover plate, so not only save manufacturing expense, and reduced leakage loss, can improve the efficiency of 1～2 percentage.
Between cover plate and end cap, be also provided with successively rolling disc and nozzle vane; Described nozzle vane is connected on end cap by fixing pin, and rolling disc covers on nozzle vane; Between cover plate and rolling disc, being also provided with cylindrically coiled spring can make rolling disc compress nozzle vane.When at adjust flux, drag link mechanism drives rolling disc rotation, cylindrically coiled spring is subject to the running torque of rolling disc, axial compression, so just can realize nozzle vane and rotate around fixing pin, during steady running condition, cylindrically coiled spring fastens rolling disc, make itself and nozzle vane close contact, realized zero clearance and axially coordinated.
Between drag link mechanism and rolling disc, adopt waist shaped hole straight-bar to be connected, and the straight pin on rolling disc change the conical structure of tape guide location into.The improvement of this structure has great convenience to mounting or dismounting decompressor, originally to overhaul, change cover plate or nozzle vane, all need the pearlife of the little ice chest of hoeing decompressor, not only lose time but also consume workman labour, and more this does not need the pearlife of the little ice chest of hoeing decompressor now, need 2 hours at most, a people just can install and remove like a cork and change expansion wheel cap or nozzle vane, convenient and efficient.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model description to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
