Abstract
The invention relates to the field of textile machinery, in particular to a shunt valve element, comprising a valve shaft and a valve sleeve; the valve shaft comprises a shaft head, a first shaft body, a second shaft body, a third shaft body and a shaft tail; the third shaft body is arranged in the valve sleeve in an inserting manner; the cross section of the second shaft body is regularly polygonal, the valve sleeve is provided with a countersink matched with the second shaft body, the countersink is internally provided with a limiting step, and the second shaft body is inserted into the countersink and abuts against the limiting step. The regularly polygonal countersink is formed in the valve sleeve, so that a stress surface of the valve sleeve is increased, the valve sleeve is uniformly stressed, and structural strength is increased; a seal ring is arranged between the countersink and the second shaft body to prevent the reduction of airtightness caused by machining error of the countersink, and meanwhile positioning holes and a positioning block are arranged, so that the valve element and the valve sleeve are more tightly connected and the structure is more stable and reliable.
Description
Technical field
The present invention relates to field of textile machinery, be specifically related to a kind of valve core of water isolating valve.
Background technique
Water jet loom shunt valve has makes high pressure water be assigned to effect in multiple nozzle water route, thus realizes having on a water jet loom function that multiple weft yarn nozzle sets timesharing sprays.And existing valve core of water isolating valve is generally made up of with the axle sleeve of the ceramic material be nested with outside mandrel the mandrel of metal, axle sleeve can reduce the frictional loss of mandrel.Existing axle sleeve is generally bonded together by structure glue, and duck in drink for a long time because of spool, some low-quality structure glue there will be inefficacy, thus cause mandrel and axle sleeve depart from or rotate, hole in through hole on mandrel and the water on axle sleeve is misplaced, thus causes high pressure water can not be assigned in each nozzle.Such as: the axle sleeve that the patent No. 201310736376.4 discloses a kind of D nibs and the mandrel matched with it, its shortcoming is that axle sleeve is pottery, frangible, due to stressed by the second spacing plane of axle sleeve during this valve core rotation, discontinuity, easily cause the stressed place of axle sleeve broken, impact uses.
Summary of the invention
The object of this invention is to provide the valve core of water isolating valve that a kind of good seal performance, structure are reliable and stable.
Above-mentioned technical purpose of the present invention is achieved by the following technical programs: a kind of valve core of water isolating valve, comprise valve shaft and valve pocket, described valve shaft comprises spindle nose, the first axle body, the second axle body, the 3rd axle body and axle tail, described 3rd axle body is plugged in valve pocket, described second axle body cross section is regular polygon, described valve pocket is provided with the counterbore matched with described second axle body, is provided with limited step in described counterbore, and described second axle body to be plugged in counterbore and to conflict on limited step.
As preferably, described second axle body cross section is square or regular pentagon or regular hexagon.
As preferably, described limited step is provided with the positioning hole of several circumference uniform distributions, and described second axle body is provided with the positioning block matched with described positioning hole.
As preferably, between described second axle body and counterbore, be provided with seal ring.
As preferably, the sidewall of described 3rd axle body is provided with the circular hole run through, and the sidewall of described valve pocket is provided with the waist-shaped hole run through, and described circular hole is communicated with waist-shaped hole.
As preferably, the lower end of described valve pocket is provided with gland nut, and described gland nut is threaded on axle tail.
As preferably, the lower end surface of described valve pocket and the surface of contact of gland nut are provided with compression line.
The present invention has following beneficial effect: the present invention by arranging the counterbore of regular polygon on valve pocket, add the stress surface of valve pocket, make its uniform force, add structural strength, and seal ring is set between counterbore and the second axle body, prevent from reducing its sealing because of counterbore machining error, positioning hole and positioning block are set again simultaneously, spool is connected more tight with valve pocket, structure is more reliable and more stable.
