Detailed description of the invention
By particular specific embodiment, embodiment of the present utility model is described below, person skilled in the art scholar can be by this descriptionDisclosed content is understood other advantages of the present utility model and effect easily.
Notice, appended graphic the illustrated structure of this description, ratio, size etc., all only in order to coordinate description to discloseContent, understands and reads for person skilled in the art scholar, not in order to limit the enforceable qualifications of the utility model, thereforeThe not technical essential meaning of tool, the adjustment of the modification of any structure, the change of proportionate relationship or size, is not affecting this practicalityUnder novel effect and the object that can reach that can produce, all should still drop on the technology contents that the utility model discloses can containIn the scope of lid. Meanwhile, in this description, quote as " on ", D score, " left side ", " right side ", " centre " andThe term of " one " etc., also only for ease of the understanding of narration, but not in order to limit the enforceable scope of the utility model, it is relativeThe change of relation or adjustment, changing under technology contents, when being also considered as the enforceable category of the utility model without essence.
As shown in Figure 1, the utility model provides a kind of syllogic sleeve adjusting valve, at least comprises: comprise sleeve assembly 1, valveBody 2, spool 3, and executing agency 4.
Described sleeve assembly 1 is contained in described valve body 2, described sleeve assembly 1 by the upper bush 11 splicing successively from top to bottom,Lower sleeve 12 and valve seat 13 form. For convenient splicing, preferably, described upper bush 11 lower surfaces and lower sleeve 12 timesEnd face is male and fomale(M&F), and described valve seat 13 upper surfaces and lower sleeve 12 upper surfaces are male and female face, and described lower sleeve 12Male and female face and described upper bush 11 male and fomale(M&F)s closely cooperate, and the male and fomale(M&F) of described lower sleeve 12 and described valve seat 13 male and female faces are tightCoordinate, see Fig. 1 and Fig. 2.
With reference to figure 1 and Fig. 2, described spool 3 is contained in described sleeve assembly 1, and described spool 3 and described valve seat 13 phasesCoupling, described spool 3 is connected with valve rod 5, sees Fig. 1 and Fig. 2.
Described valve body 2 upper ends are provided with the valve gap 6 for pressing described spool 3, and described valve gap 6 seals with described upper bush 11Connect; Described valve rod 5 is connected with described executing agency 4 through described valve gap 6, sees Fig. 1 and Fig. 2.
Preferably, described valve seat 13 outer wall lower end edge outward flanges offer circumferential recessed groove, in described circumferential recessed groove, valve are installedSeat cushion sheet 8, and described valve seat pad 8 lateral surfaces and lower surface be against on described valve body 2, sees Fig. 2.
Preferably, upper bush 11 outer wall upper ends have step surface, and described valve body 2 inwall upper ends also have step surface, two institutesState step surface and be provided with valve body pad 7, and described valve body pad 7 end faces are against described valve gap 6 lower surfaces, see Fig. 2.
With reference to figure 1 and Fig. 2, when assembling, first described valve seat pad 8 is put into described valve body 2, then by described sleeve assembly 1Put into described valve body 2, then put into the spool 3 that valve rod 5 has been installed; Valve body pad 7 and valve gap 6 are then installed successively,Described valve gap 6 adopts screw bolt and nut to be fixedly connected with described valve body 2; In described valve gap 6, insert again filler and use valve gap 6Gland compress, finally described valve rod 5 is linked together with described executing agency 4, so just assembled this syllogic coverCylinder control valve.
In addition, described valve seat 13 inwalls are provided with the hardened layer of being made up of carbide alloy. The hardness of hardened layer is higher, described valve seatHardened layer on 13 inwalls can reduce cavitation erosion and damage valve seat 13, thereby has extended valve seat 13 long service life.
In addition, described upper bush 11 inwalls are provided with the hardened layer of being made up of carbide alloy. The hardness of hardened layer is higher, described upper coverHardened layer on cylinder 11 inwalls can reduce cavitation erosion and damage upper bush 11, thereby has extended upper bush 11 long service life. PreferablyGround, is only provided with hardened layer at described upper bush 11 inwalls with the place that spool 3 contacts, and not only can avoid like this upper bush11 are damaged by cavitation erosion, have also reduced described upper bush 11 manufacturing costs.
In sum, the utility model provides syllogic sleeve adjusting valve, because described sleeve assembly 1 is by spelling successively from top to bottomThe upper bush 11, lower sleeve 12 and the valve seat 13 that connect form; In the course of work, as described upper bush 11, lower sleeve 12 andIn valve seat 13, when one or two damage parts, only need to change corresponding part, need not change whole described sleeve assembly 1, therefore largeReduce greatly maintenance cost. So the utility model has effectively overcome various shortcoming of the prior art and the utilization of tool high industrialBe worth.
