Abstract
The utility model discloses a nozzle for a textile machine. The nozzle comprises a nozzle base (1) and a nozzle (2), wherein the nozzle (2) is installed in the nozzle base; six spraying holes (3) are formed on the end, far away from the nozzle base, of the nozzle. The nozzle is characterized in that an inner chamber A of the nozzle (1) is a tapered tube chamber; seven helix flow guide grooves are arranged on the tapered tube chamber; the inner diameter of the finer end of the tapered tube chamber is equal to the inner diameter of the nozzle (2); the inner diameter of an inner chamber B of the nozzle base is equal to the outer diameter of the nozzle (2); two sealing grooves are arranged at the inner chamber B of the nozzle base (1); two sealing grooves matched with the two sealing grooves arranged at the inner chamber B are also arranged in the corresponding positions of the nozzle (2); sealing gel (4) is arranged at the sealing grooves; the six spraying holes are arranged in a pentagon; and the apertures of the holes at the peak of the pentagon are smaller than the aperture of the hole at the center of the pentagon. The nozzle has the beneficial effects of reducing the gas consumption, improving the gas spraying quality and being wear-resisting and longer in service life.
Description
Technical field
The utility model relates to technical field of textile machine, especially relates to a kind of textile machines nozzle.
Background technology
The pilot jet operation principle of open-end spinning loom is that after the shed open of warp thread introducing weft yarn was opened, the pilot jet that is installed in the warp thread bottom passed warp thread and gets into shed open, and compressed air gets into nozzle carrier through pipeline; From nozzle bore ejection air-flow, to introduce warp thread to the weft yarn of main burner ejection and accomplish wefting insertion work, nozzle withdraws from warp thread and gets back to original position; The flow quality of nozzle ejection directly influences the wefting insertion quality, and impulse stroke of nozzle will rub twice with weft yarn, in thousands of times friction; Certainly will be affected the service life of nozzle, and in the prior art, the internal diameter of pilot jet is less than the internal diameter of nozzle carrier; After nozzle sprays into nozzle carrier, just form a circle step, produce resistance when causing air-flow when nozzle carrier leads to nozzle, to run into this step; Weaken the flow and the flow velocity of air-flow, the spray orifice force value is reduced, influence the quality of jet-stream wind.
The utility model content
The purpose of the utility model is exactly in order to address the above problem, and a kind of gas consumption that reduces is provided, and improves jet quality, and is wear-resisting, the textile machines nozzle of longer service life.
To achieve these goals, the utility model adopts following technical scheme:
A kind of textile machines nozzle comprises nozzle carrier and is installed on the nozzle in the nozzle carrier that said nozzle nozzle carrier end far away is provided with spray orifice; It is characterized in that; Said nozzle chamber A place is conical tube chamber, and seven road spiral stream guidance grooves are set on this taper shape tube chamber, and conical tube chamber thinner end internal diameter equals nozzle inside diameter; Nozzle carrier inner chamber B place internal diameter equals the external diameter of nozzle; Said nozzle carrier inner chamber B place is provided with two seal grooves, and said nozzle corresponding position also is provided with the seal groove of two couplings, and the place is provided with fluid sealant in seal groove.
Said spray orifice hole count is six holes, and the hole is positioned at the aperture of the aperture in hole, place, pentagon summit less than hole, pentagon center according to pentagonal array.
Said spray orifice hole count is nine holes, and the hole is positioned at the aperture of the aperture in hole, circular central place greater than hole, circular edge place according to circular arrangement.
The beneficial effect of the utility model is: nozzle is a wheel chair access level and smooth chamber, and air-flow can be smooth and easy through nozzle, and flow velocity and flow unchanged; Improve jet quality greatly, and between nozzle carrier and nozzle fluid sealant is set, effectively solve the problem of sealing difference; It is strong that the pentagon design of spray orifice can make the gas beam of ejection concentrate; Improve wefting insertion effect and quality, reduce gas consumption, reduce production costs.

Fig. 2 is the spray orifice pentagon layout drawing of textile machines nozzle.。
Fig. 3 is a H-H profile among Fig. 1.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
Shown in Fig. 1-3, a kind of textile machines nozzle comprises nozzle carrier 1 and is installed on the nozzle 2 in the nozzle carrier; Be smooth inner lumen in the nozzle, what air-flow can smoothness passes through, and jet quality improves greatly; Said nozzle nozzle carrier end far away is provided with spray orifice 3, and the nozzle that spray orifice one end is set is oblate, and said nozzle 1 inner chamber A place is conical tube chamber; The air-flow effect is bigger for compiling, and can effectively improve gas pressure, and seven road spiral stream guidance grooves are set on this taper shape tube chamber; Make the air-flow of straight-line pass become the air-flow that rotatablely moves, under centrifugal action, improve air-flow velocity; Conical tube chamber thinner end internal diameter equals nozzle 2 internal diameters, and nozzle carrier inner chamber B place internal diameter equals the external diameter of nozzle 2, and said nozzle carrier 1 inner chamber B place is provided with two seal grooves; Said nozzle 2 corresponding positions also are provided with the seal groove of two couplings, in the seal groove place fluid sealant 4 are set, and effectively solve the sealing problem between nozzle and nozzle carrier.
As shown in Figure 1, said spray orifice hole count is nine holes, and the hole is positioned at the aperture of the aperture in hole, circular central place greater than hole, circular edge place according to circular arrangement.
As shown in Figure 2, said spray orifice hole count is six holes, and the hole is positioned at the aperture of the aperture in hole, place, pentagon summit less than hole, pentagon center according to pentagonal array.
The above is merely the preferred implementation of the utility model, and the protection domain of the utility model is not limited in above-mentioned embodiment, and every technical scheme that belongs to the utility model principle all belongs to the protection domain of the utility model.For a person skilled in the art, some improvement of under the prerequisite of the principle that does not break away from the utility model, carrying out, these improve the protection domain that also should be regarded as the utility model.
