Abstract
The utility model discloses a double air-source nozzle capable of adjusting overflowing area, which comprises a nozzle (1) and an outer sleeve (2). An air outlet end of the nozzle (1) presents conical-surface structure. The characteristics are as follows: the air outlet end of the nozzle (1) is provided with at least two slots (3) which at least extend to the conical-surface structure and divide the outlet end of the nozzle (1) into two nozzle sheets of which the roots are connected together; the outer sleeve (2) is installed on the nozzle (1) in a rotating way, and the position of the outer sleeve (2) on the nozzle (1) opposite to the conical-surface structure of the nozzle (1) presents the conical-surface structure. The nozzle provided by the utility model has simple structure and is convenient to adjust.
Description
Technical field
The utility model relates to a kind of gas-fired equipment, especially a kind of double-air-supply nozzle, the specifically a kind of double-air-supply nozzle that can regulate area of passage.
Background technology
As everyone knows, in the dual gas supply system, because source of the gas calorific value difference, so the area of passage of nozzle is also different.Existing double-air-supply nozzle is to walk always to regulate area of passage according to what different sources of the gas changed gas circuit in the nozzle mostly, a series of problems such as there is complex structure in the double-air-supply nozzle of this structure, and manufacture difficulty is big.
Summary of the invention
The purpose of this utility model is at existing double-air-supply nozzle complex structure, the problem that manufacture difficulty is big, design a kind of simple in structure, thereby can change the double-air-supply nozzle that can regulate area of passage that area of passage adapts to different source of the gas needs by simple rotation.
The technical solution of the utility model is:
A kind of double-air-supply nozzle that can regulate area of passage, comprise nozzle 1 and overcoat 2, the outlet side of nozzle 1 is cone structure, it is characterized in that on the outlet side of nozzle 1, having at least two flutings 3, and described fluting 3 extends to cone structure at least and the port of export of nozzle 1 is divided into two nozzle pieces that root links to each other at least, described overcoat 2 spinnings are on nozzle 1, and the cone structure relative position place on itself and the nozzle 1 also is cone structure so that the nozzle piece of nozzle 1 head is opened or closed.
The beneficial effects of the utility model:
The utility model is simple in structure, and is easily manufactured, only needs several the flutings of nozzle head processing in routine, re-uses that gland dwindles or the distance that strengthens between the fluting can realize the area of passage adjusting.
Description of drawings
Fig. 1 is a three-dimensional decomposition texture schematic diagram of the present utility model.
Fig. 2 is that the natural gas state, area of passage of working in of the present utility model is enclosed within position view on the nozzle when maximum outward.
Fig. 3 is liquefied gas state, the area of passage position view of hour overcoat on nozzle that work in of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figure 1.
A kind of double-air-supply nozzle that can regulate area of passage, comprise nozzle 1 and overcoat 2, the outlet side of nozzle 1 is cone structure, on the outlet side of nozzle 1, have at least two (the best is three) fluting 3, and described fluting 3 extends to cone structure at least and with the port of export of nozzle 1 be divided at least that root links to each other two (when fluting is three, the quantity of nozzle piece also is three) nozzle piece, described overcoat 2 spinnings are on nozzle 1, and the cone structure relative position place on itself and the nozzle 1 is also that cone structure opens with the nozzle piece that enables nozzle 1 head or is closed.
When the area of passage of needs bigger, overcoat 2 only be spinning on nozzle 1, the internal conical surface of overcoat 2 also plays effect of contraction with the conical surface to nozzle 1 head, nozzle piece is in free state, this moment, the area of passage of nozzle equaled design area, as shown in Figure 2.When the area of passage of needs hour, rotatable overcoat makes the inner conical surface of inner conical surface extruding jet nozzle 1 head of overcoat 2, forces nozzle piece to shrink, thereby corrects one's mistakes flow area, as shown in Figure 3.
The utility model does not relate to the part prior art that maybe can adopt all same as the prior art to be realized.
Claims (1)
1. the double-air-supply nozzle that can regulate area of passage, comprise nozzle (1) and overcoat (2), the outlet side of nozzle (1) is cone structure, it is characterized in that on the outlet side of nozzle (1), having at least two flutings (3), and described fluting (3) extends to cone structure at least and the port of export of nozzle (1) is divided into two nozzle pieces that root links to each other at least, described overcoat (2) spinning is on nozzle (1), and the cone structure relative position place on itself and the nozzle (1) also is cone structure.
