Abstract
The invention provides a reducing type sprayer of a water-jet loom. The reducing type sprayer comprises a spraying pipe, wherein the inner wall of the nozzle side of the spraying pipe is annularly provided with an annular bag body, wherein the annular bag body is controlled to expand or shrink via a gas or liquid state working medium by a pressure control device, and is subjected to size increment deformation in the process of jetting water stream by the spraying pipe. According to the invention, the inner diameter of the annular bag body is decreased progressively in the process of jetting weft yarns by the spraying pipe; the water amount for dragging weft yarns to fly is controlled; the shorter the flight path of the weft yarns is, the small the diameter of the water stream is, and the aim of saving water for spraying is achieved.
Description
Art
The present invention relates to weaving machine equipment field, especially, is a kind of reducing type shower nozzle for water jet looms.
Background technology
Water jet looms belongs to jet loom, is to utilize water as wefting insertion medium, produces frictional traction by jet water course to weft yarn, makes the weft yarn on fixed bobbin introduce shed open.Because the concentration of current is better, without any anti-current disperser on water jet looms, even if its reed width also can reach more than two meters like this.The current convergence of water jet looms is good, and water is also large to the frictional traction of weft yarn in addition, therefore makes the weft yarn flying speed of water jet looms, loom speed all occupies first of all kinds of loom.
The initial stage that water jet looms sprays, the head end of the current weft traction sprayed flies to picking end, bore due to shower nozzle is forever constant, therefore whole injection picking process, current are all with identical diameter weft traction, and this just forms a problem, the stretch footpath of tail end owing to only need fly very little of the picking of weft yarn, therefore only need consume the very little kinetic energy of current just can complete, such filling insertion way is unfavorable for that water jet looms is for the environmental requirement of saving water source.
Summary of the invention
In order to solve the problem, the object of the present invention is to provide a kind of water jet looms reducing type shower nozzle, this water jet looms reducing type shower nozzle can save the water yield required for water jet looms wefting insertion.
The technical solution adopted for the present invention to solve the technical problems is:
This water jet looms reducing type shower nozzle comprises jet pipe, the inwall of the spout side of described jet pipe is equipped with annular balloon body, described annular utricule controls its expansion or contraction by the working medium of gaseous state or liquid state by pressure control device, and described annular utricule completes the deformation that volume increases progressively in the process of jet pipe jet water course.
As preferably, by jet pipe core and coaxial sleeve, the jet pipe cover outside jet pipe core forms described jet pipe, the pressure chamber of airtight formation one annular between described jet pipe core and jet pipe cover, the inwall of the spout side of described jet pipe core has annulus, described pressure chamber is communicated with described annulus, the outer wall of described jet pipe core closes described annulus by a rubber sleeve, described jet pipe puts the working medium import having and be communicated with described pressure chamber, described working medium import is provided with flow-limiting valve, described rubber sleeve forms described annular utricule, and described flow-limiting valve forms pressure control device.
As preferably, described jet pipe cover forms with the contact surface of described jet pipe core inner the clamping area fixing rubber sleeve two ends.
As preferably, be positioned at described annulus to the internal diameter of the jet pipe in-core wall of spout and increase progressively gradually.
As preferably, described working medium is from the water of the band pressure of water jet looms self.
The invention has the advantages that:
During jet pipe jet water course, the section that described rubber sleeve is positioned at described annulus completes the continuous decrementing procedure of internal diameter, the internal diameter of rubber sleeve controls the diameter of jet water course, so just can according to press weft yarn flight path number, control weft traction flight the water yield number, the position that weft yarn flight path is shorter, the diameter of current is fewer, reaches the object of saving water spray.
Accompanying drawing explanation
Fig. 1 is the structural representation of this water jet looms reducing type shower nozzle embodiment two.
Fig. 2 is the structural representation in this water jet looms reducing type shower nozzle embodiment two after annular capsule diameters change.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further described:
Embodiment one:
Consult Fig. 1, in the present embodiment, this water jet looms reducing type shower nozzle comprises jet pipe, the inwall of the spout side of described jet pipe is equipped with annular balloon body, described annular utricule controls its expansion or contraction by the working medium of gaseous state or liquid state by pressure control device, and described annular utricule completes the deformation that volume increases progressively in the process of jet pipe jet water course.
Described annular utricule is made up of the rubber ring of annular, and described pressure control device can adopt air pressure or hydraulic pump to coordinate pressure controller to form.
Embodiment two:
Consult Fig. 1, in the present embodiment, by jet pipe core 100 and coaxial sleeve, the jet pipe cover 200 outside jet pipe core 100 forms described jet pipe, the pressure chamber 400 of airtight formation one annular between described jet pipe core 100 and jet pipe cover 200, the inwall of the spout side of described jet pipe core 100 has annulus, described pressure chamber 400 is communicated with described annulus, the outer wall of described jet pipe core 100 closes described annulus by a rubber sleeve 300, described jet pipe cover 200 has the working medium import 210 being communicated with described pressure chamber 400, described working medium import 210 is provided with flow-limiting valve 220, described rubber sleeve 300 completes the deformation that internal diameter C successively decreases in the process of jet pipe jet water course.
The working medium of band pressure is injected in described working medium import 210 when jet pipe sprays, described working medium makes the pressure linear increment in described pressure chamber 400 because of the effect of described flow-limiting valve 220, described rubber sleeve 300 internal diameter reduces because of expansion, therefore the current diameter that jet pipe sprays also successively decreases, after jet pipe stops spraying, the working medium of described pressure chamber refluxes out described flow-limiting valve 220, and described rubber sleeve 300 internal diameter expands because of contraction, circulation said process, forms continuous print operation acts.
Above-mentioned water jet looms reducing type shower nozzle, described jet pipe cover 200 and the contact surface of described jet pipe core 100 inside form the clamping area at fixing rubber sleeve 300 two ends.
Above-mentioned water jet looms reducing type shower nozzle, is positioned at described annulus and increases progressively gradually to the internal diameter D of jet pipe core 100 inwall of spout.
Above-mentioned water jet looms reducing type shower nozzle, described working medium is from the water of the band pressure of water jet looms self.
Consult Fig. 1 and Fig. 2, in the process of jet pipe jet water course weft traction, the section that described rubber sleeve 300 is positioned at described annulus completes the continuous decrementing procedure of internal diameter C, the internal diameter C of rubber sleeve 300 controls the diameter of jet water course, so just can according to press weft yarn flight path number, control weft traction flight the water yield number, the position that weft yarn flight path is shorter, the diameter of current is fewer, reaches the object of saving water spray.
Describedly be only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included in protection scope of the present invention.
