Abstract

The utility model relates to an energy-saving valve mouth connector, belonging to the valve mouth connector, which can be used in various high rate jet looms. The electromagnetic valves and the additional mouths used in various deformed reed type jet loom at home and abroad are all in split type of connection of valves and jet used hoses, and each electromagnetic valve has three to five additional mouths. Not only each connection hose is long to cause the waste when the residual air current is exhausted, but also the three to five additional mouths simultaneously jet air outward when filling insertion, and bigger waste of the air current of the evacuating part can be caused before the filling yarn head ends arrive. The valve mouth connector of the utility model realizes a whole structural form of one valve with two mouths or one mouth. By calculating, only canceling hose connection can save air and energy by 11. 63%.

Description

Energy-conservation valve nozzle conjoined device

One. technical field:

The utility model is relevant with valve and nozzle, is mainly concerned with the valve spray and fuses, and belongs to textile equipment, is applicable to high-speed air-jet looms.

Two. technical background:

Used electromagnetic valve and pilot jet all is split type on the current domestic and international various special-shaped reed formula air-jet looms, and both connect as gas channel by flexible pipe, and every electromagnetic valve connects 3～5 pilot jets.There are three defectives in being provided with like this:

1. the flexible pipe that is 250mm with an average length between every electromagnetic valve and the pilot jet is connected as gas channel, and after a wefting insertion finished closed electromagnetic valve, the high pressure draught that remains in this section flexible pipe will run off from the ground emptying in vain, cause waste.

2. every electromagnetic valve connects 3～5 pilot jets, has 3～5 pilot jets simultaneously outwards jet when making wefting insertion in 160～320mm length, certainly will make dirty secondary air in the emptying of also no show forward part of weft yarn head end, also can cause bigger waste.

3. the spool reciprocating motion of electromagnetic valve and rely on spring reset, very easily wearing and tearing gas leakage, malfunctioning, high speed bad adaptability.

Based on as can be known above-mentioned, the air consumption of the current air-jet loom of generally acknowledging is very big, and is directly relevant with this valve, mouth split set-up mode.

Three. summary of the invention:

The purpose of this utility model is a kind of energy-conservation valve nozzle conjoined device of design, connects flexible pipe with cancellation and comes solar term to economize energy; Improve its high speed adaptability with micro machine control spool, use for various air-jet looms.

Four. technical measures:

Technical measures of the present utility model are as follows:

The structure of energy-conservation valve nozzle conjoined device such as accompanying drawing.1 is valve body among the figure, and 2 and 3 is pilot jet, and 1 and 2 and 3 link together by screw becomes the valve body conjoined device.4 is the nozzle copper sleeve, and 5 is gas channel, and 6 is the screw that air inlet is connected with appendix, and 7 is air chamber, and 8 is four holes that are connected with slay.9 is spool, is rigidly connected with the micro-motor (not shown) or flexibly connects.

Five. advantage and effect

The utility model has the advantages that energy-conservation, the high speed conformability is good.Analyze accompanying drawing and can learn and adapt at a high speed how to realize energy-conservation.To fuse and abolished length L be 250mm for valve body 1 and

pilot jet

2 and 3 among the figure, and internal diameter φ is the air hose of 4.8mm.If a kind of speed of a motor vehicle n of air-jet loom is 700r/min, 4 pilot jets of every electromagnetic valve band, every total pilot jet m of loom is 24.With a valve band two mouths is example, and as calculated, the volume of gas Vd that cancels remaining emptying in 24 air hoses is:

Vd＝(π×φ)/4×L×m×n

＝0.076M/min

Total air consumption V of 24 pilot jets of known this air-jet loom is that the percentage that 0.7M/min ， The Vd accounts for V is:

Vd/V＝11.63％

This explanation, after the utility model was implemented, the air consumption that only this item is saved just accounted for 11.63% of the total air consumption of complete machine pilot jet.The technical scheme of a valve band two mouths has also been stopped 3～5 bigger wastes that the auxilliary gaseous blast part emptying in the simultaneously outside jet downstream of causing of pilot jets is caused simultaneously.High speed conformability of the present utility model is to rotate by the high speed of micro machine to realize, the anglec of rotation of its spool is 30 °～90 °.The machine operation frequency is 35HZ～45HZ.

Six. description of drawings:

Accompanying drawing is energy-conservation valve nozzle conjoined device figure.

Wherein: the 1---valve body, 2, the 3---pilot jet, 4---nozzle copper sheathing,

The 5---gas channel, 6---air inlet screw, the 7---air chamber,

Four holes that 8---is connected with reed, the 9---spool.

Seven. the specific embodiment:

With reference to accompanying drawing, introduce a kind of major parameter of energy-conservation valve nozzle conjoined device of a valve band two mouths that are applicable to air-jet loom: the pilot jet total height is 60mm, spray orifice aperture φ 1.4mm, spray to angle β=6 °, what jet pipe copper sleeve lower end was connected with valve body is the M8 screw thread, and its internal diameter φ 3.5mm is as gas channel.The air inlet screw of valve body is that M12 links to each other with compressed air inlet pipe.Valve body length is 86mm, and width is 22mm, is 32mm highly, and the centre-to-centre spacing that two pilot jet screws are installed is 70mm.The micro machine operating frequency is 36HZ, the φ 10mm of valve core diameter, and passage aperture φ 3.5mm, the spool anglec of rotation is 45 °.

Claims

1. energy-conservation valve nozzle conjoined device, it is characterized in that: valve body and pilot jet fuse.

2. valve nozzle conjoined device as claimed in claim 1 is characterized in that two pilot jets of a valve band or a pilot jet.

3. valve nozzle conjoined device as claimed in claim 1 is characterized in that valve core rotation, and the span of the anglec of rotation is 25 °～90 °.
