Abstract
The invention relates to a conversion valve. A hollow inner wall of a valve body is in interference fit with a ceramic valve sleeve; a ceramic valve core is driven by a top motor; a shifting block is used for limiting; the middle part of the valve body is provided with a water inlet, a water outlet, an upper drain pipe and a lower drain pipe; the periphery of the valve core is provided with a ring-shaped concave water collecting tank; the valve core is in integrated clearance fit with the valve sleeve; the position of the upper drain pipe corresponds to the water collecting tank; and the position of the lower drain pipe corresponds to a lower water collecting cavity. The integrated ceramic valve core of the invention has the advantages of reasonable structure, convenient assembly, high installing efficiency and low manufacturing cost, and capability of greatly improving the reliability of the conversion valve and prolonging the service life of the conversion valve.
Description
Technical field
The present invention relates to the textile machinery accessories field, especially the switching valve used of weaving machine with water spraying.
Background technique
Weaving machine with water spraying adopts switching valve to realize turning to of Weaving shuttle, and in actual use, Weaving shuttle is carried out the frequent to-and-fro motion of high speed, therefore needs switching valve to turn to switching fast, and per minute need switch 600～800 times usually.Switching valve commonly used at present adopts single swing-arm type single shaft to hold supporting means, though adopt seal ring to seal, because frequent rotation; Therefore the long-term back (being generally about a year) of using, seal ring can lose efficacy, and this moment, water capacity easy to leak was to the metal bearing part; Cause bearing rust, in case get rusty, then running shaft can squint; Cause single spiral arm to produce great moment of torsion, motor load strengthens and damages to cause main shaft to twist off perhaps.The maintain and replace switching valve need stop the operation of whole weaving machine, time-consuming consumption power, and manufacturer's loss is very big.
Patent " 200920071783.7---water jet loom is used shunt valve " discloses a kind of switching valve that adopts two supports Ceramic shaft sleeve up and down to replace one-sided metal bearing, and this structure can solve shunt valve and leak and metal bearing is got rusty and cause motor load to strengthen and the problem damaged.It is very high that but the quality of fit between the spool of high speed rotating and the valve pocket requires; Therefore in the actual production manufacture process; The coaxality that guarantees three central shafts of upper shaft sleeve, middle part spool and bottom axle sleeve simultaneously requires can not reach basically; And in use along with the variation of temperature, this cooperation of crossing constraint also can cause spool often stuck; Can produce and leak in a large number and increase tolerance, the water spray underpressure at last can't normal boot-strap.Therefore this switching valve can not be used for the actual production use.
Summary of the invention
The applicant can produce to above-mentioned existing metal bearing switching valve gets rusty, takes place fracture damage; And that ceramic bearing switching valve assembly precision requires is too high, can't make and be used for shortcoming such as production; Provide a kind of rational in infrastructure; Integrated type ceramic valve core easy to assembly does not have the switching valve of bearing, thereby has improved the reliability of switching valve greatly, has prolonged the working life of switching valve.
The technological scheme that the present invention adopted is following:
A kind of switching valve; The hollow wall interference fit of valve body has ceramic valve pocket, and ceramic valve core carries out spacing by the top motor driving through shifting block; The valve body middle part is provided with water intake, water outlet and goes up waste pipe and following waste pipe, and the side face of described spool is provided with the recessed collecting annulus of annular; Whole Spielpassung between spool and the valve pocket, the said waste pipe position of going up are corresponding to collecting annulus, and said waste pipe position down is corresponding to following collect cavity.It is further characterized in that:
Cooperating monolateral gap between described spool and the valve pocket is 3～6 μ m; Preferred value is 4 μ m;
Described spool and valve pocket carry out axially locating through valve gap and location piece.
The present invention is provided with the recessed collecting annulus of annular at the side face of ceramic valve core, and the water that infiltrates between spool and the valve pocket is in time discharged, and has effectively prevented water seepage outside switching valve, need not to use Sealing.
The present invention adopts spool and valve pocket to carry out overall co-ordination; Need not to install Sealing, bearing support etc.; Up and down the complicated cooperating structure of two supports is for the accurate requirement of coaxality to have avoided available technology adopting metal bearing list point supporting or Ceramic shaft sleeve, and installation efficiency is high, low cost of manufacture.The single installation time of the switching valve of existing technology is 2～3 hours, and installation time of the present invention only needs about 20 minutes.
Spool of the present invention and valve pocket overall co-ordination simple and reliable for structure; Coaxality is high, and stable, high density ceramic material wear resistance is good; Need not any Lubricants and get final product high speed operation; Avoided metal bearing get rusty and Ceramic shaft sleeve is difficult to coaxial shortcoming, improve working life greatly, is 3～5 times of existing switching valve; Therefore also improve the start efficient of weaving machine with water spraying, practiced thrift the cost of production of the factory of weaving cotton cloth.

Fig. 3 is the right elevation of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present invention is described.
Like Fig. 1, shown in Figure 3, the hollow wall interference fit of the valve body 8 of switching valve according to the invention has ceramic valve pocket 4, and ceramic valve core 5 is interference fitted in stainless steel axis outer circumferential face, and stainless steel axis top is driven by motor 1, carries out spacing through shifting block 2; As shown in Figure 2, the side face of ceramic valve core 5 is provided with the recessed collecting annulus 6 of a circle annular; Little Spielpassung between ceramic valve core 5 and the ceramic valve pocket 4, its monolateral gap is 3～6 μ m, is preferably 4 μ m; Valve pocket 4 carries out axially locating with spool 5 through upper valve cap 3, ceramics 10 supportings of location, bottom; Carry out airtight formation Seal cage in valve body 8 bottoms through capping 12; Valve body 8 middle parts are provided with a water intake 9, two water outlets 14 and go up waste pipe 7 and following waste pipe 13; Last waste pipe 7 positions are corresponding to collecting annulus 6, and following waste pipe 13 positions are corresponding to following collect cavity 11.
When reality was used, shift valve spool is back and forth rotation at a high speed, turns to about the water with water intake 9 and distributes to two water outlets 14; A spot of water is in the gap of infiltrating under the effect of pressure between ceramic valve core 5 and the ceramic valve pocket 4, and downward water drops on down collect cavity 11 and passes through waste pipe 13 discharges down, and the water that makes progress arrives collecting annulus 6; Because it is big that the space becomes, so hydraulic pressure reduces immediately, discharges through last waste pipe 7; Can not continue uply, need not to use other Sealings from valve gap 3 seepages.
More than describing is to explanation of the present invention, is not that institute of the present invention restricted portion is referring to claim to the qualification of invention, and under the situation of spirit of the present invention, the present invention can do any type of modification.
