Abstract
The invention provides a spray nozzle structure of a turbo expander. The spray nozzle structure comprises an annular spray nozzle main body and a pull rod mechanism for adjusting the opening/closing of the spray nozzle main body, wherein the spray nozzle main body comprises a cover plate, a rotary disc and an end cover, the pull rod mechanism is connected in the radial direction of the rotary disc; the single face of the end cover is fixedly arranged on the cover plate; the rotary disc and a spray nozzle blade are arranged between the cover plate and the end cover in sequence; the spray nozzle blade is connected onto the end cover through a fixing pin; the rotary disc is pressed and covered on the spray nozzle blade; a cylindrical helical spring is also arranged between the cover plate and the rotary disc, and can enable the rotary disc to tightly press the spray nozzle blade. By applying the spray nozzle structure, as the rotary disc and the spray nozzle blade can be in tight contact, the zero-clearance axial fitting is realized; meanwhile, the connection way of the pull rod mechanism greatly facilitates the detachment of the mechanism, so that the efficiency of a whole machine is improved greatly, and the purposes of energy conservation and efficiency improvement are realized.
Description
Technical field
The present invention relates to mechanical field, particularly relate 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, the structure of our the critical component-adjustable nozzle to decompressor has been made initiative innovative development.
In turbo-expander, the critical piece that affects efficiency has nozzle and expansion wheel, wherein having the greatest impact of nozzle, 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 difficulty, and working efficiency is low, is unfavorable for technological innovation.
Summary of the invention
The technical problem that the present invention 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 present invention adopt a technological scheme be to provide a kind of 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 in upwards cylinder lever connecting rod mechanism of 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 locating stud on rolling disc adopt the conical structure of tape guide location.
The invention has the beneficial effects as follows: 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.
Brief description of the drawings

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 invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
Refer to accompanying drawing 1 to 4, the embodiment of the present invention comprises:
A kind of spray nozzle of turboexpander structure, 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 in upwards cylinder lever connecting rod mechanism of 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, when 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 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 embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes description of the present invention 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 invention.
