Abstract
The utility model relates to the field of textile machinery, concretely relates to valve core of water isolating valve, including valve shaft and valve barrel, the valve shaft includes spindle nose, first axle body, second axle body, third axle body and axle tail, the third axle body is inserted and is established in the valve barrel, second axle body cross section is regular polygon, be equipped with on the valve barrel with second axle body matched with counter bore, be equipped with spacing step in the counter bore, the second axle body is inserted and is established in the counter bore and conflict on spacing step. The utility model discloses a set up regular polygon's counter bore on the valve barrel, increased the stress surface of valve barrel, make its atress even, increased structural strength to setting up the sealing washer between counter bore and second axle body, preventing to set up locating hole and locating piece again simultaneously because of counter bore machining error reduces its leakproofness, it is more inseparable to make case and valve barrel connect, and the structure is more reliable and more stable.
Description
Technical field
The utility model relates to field of textile machinery, is 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.
Model utility content
The purpose of this utility model is to provide the reliable and stable valve core of water isolating valve of a kind of good seal performance, structure.
Above-mentioned technical purpose of the present utility model 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 utility model has following beneficial effect: the utility model 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.
