Abstract
The utility model discloses a valve core assembly, comprising a rotary shaft, a valve core body and a locating pin, wherein the valve core body is provided with an adjusting cavity; the rotary shaft is sleeved in the adjusting cavity and in clearance fit with the adjusting cavity; a locating hole is formed on the wall of the adjusting cavity; a blind hole is formed on the rotary shaft; and the locating pin passes through the locating hole to the blind hole, and is in interference fit with the locating hole and/or the blind hole, so that the manufacturing procedures can be effectively decreased, therefore the production efficiency is improved.
Description
Technical field
The utility model relates to a kind of Spool assembly, and it is applicable to gas valve core or the water valve core of gas water-heater.
Background technique
The Spool assembly of existing gas water-heater is comprised of spool body, rotating shaft and locating stud, rotating shaft is provided with the through hole of fixed locating stud, first interference fit is carried out in the adjusting chamber of rotating shaft and spool during assembling, then the through hole in locating stud and the rotating shaft is carried out interference fit, the step of two interference fit need to progressively be carried out, and causes to have the problems such as complex procedures, manufacturing efficiency be low.For overcoming these defectives, the gas water-heater Spool assembly is improved.
Summary of the invention
Technical problem to be solved by this invention provides a kind of Spool assembly, and it can reduce manufacturing procedure effectively, enhances productivity.
The technological scheme that its technical problem that solves the utility model adopts is: comprise rotating shaft, spool body, locating stud, the spool body is provided with the adjusting cavity, rotating shaft be placed in regulate in the cavity and with regulate the cavity Spielpassung, the wall of regulating cavity is provided with positioning hole, rotating shaft is provided with blind hole, locating stud passes positioning hole to blind hole, and with positioning hole and/or blind hole interference fit.
Be provided with annular knurl with positioning hole and blind hole contacting point in the middle of the described locating stud, locating stud is by annular knurl and positioning hole and/or blind hole interference fit.
Described locating stud and positioning hole and blind hole interference fit, positioning hole is identical with the diameter of blind hole.
Described spool body is made by aluminium or stainless steel material.
Described rotating shaft is made by aluminium or iron or stainless steel material.
Described locating stud is made by aluminium or iron or stainless steel material.
The utility model is compared the beneficial effect that produces with background technique:
Since the utility model adopts rotating shaft to be placed in regulate in the cavity and with regulate the cavity Spielpassung, the wall of regulating cavity is provided with positioning hole, rotating shaft is provided with blind hole, locating stud passes positioning hole to blind hole, and with the scheme of positioning hole and/or blind hole interference fit, directly rotating shaft is put into the adjusting cavity of spool during assembling, then locating stud is squeezed into positioning hole and blind hole, can effectively reduce manufacturing procedure, enhance productivity.

Embodiment: referring to accompanying drawing 1, accompanying drawing 2, accompanying drawing 3, accompanying drawing 4, accompanying drawing 5, shown in the accompanying drawing 6, the present embodiment comprises rotating shaft 1, spool body 2, locating stud 3, spool body 2 is provided with regulates cavity 7, rotating shaft 1 be placed in regulate in the cavity 7 and with regulate cavity 7 Spielpassung, the wall of regulating cavity 7 is provided with positioning hole 4, rotating shaft 1 is provided with blind hole 5, locating stud 3 passes positioning hole 4 to blind hole 5, the diameter of locating stud 3 centres and positioning hole 4 and blind hole 5 contacting points is greater than the diameter of positioning hole 4 and blind hole 5, positioning hole 4 is identical with the diameter of blind hole 5, locating stud 3 and positioning hole 4 and 5 while of blind hole interference fit.Locating stud 3 has the diameter of an end at least less than the diameter of positioning hole 4 and blind hole 5, does not need to check locating stud 3 which end in order to install for to the inner again, and the diameter at locating stud 3 two ends is identical in the present embodiment, all less than the diameter of positioning hole 4 and blind hole 5.
Further, be provided with annular knurl 8 with positioning hole 4 and blind hole 5 contacting points in the middle of the locating stud 3, the diameter of annular knurl 8 is greater than the diameter of positioning hole 4 and blind hole 5, and locating stud 3 is by annular knurl 8 positioning holes 4 and blind hole 5 interference fit, and annular knurl 8 can increase frictional force, prevents from skidding.In addition, because Copper Product in China is rare, the copper valency is higher, and the spool body 2 in the utility model is made by aluminium or stainless steel material, and rotating shaft 1 is made by aluminium or iron or stainless steel material, and locating stud 3 is made by aluminium or iron or stainless steel material, can effectively reduce cost.
During assembling, owing to regulating cavity 7 internal diameters greater than the external diameter of rotating shaft 1, can directly rotating shaft 1 easily be put into regulate cavity 7 and with adjusting cavity 7 Spielpassung, and make positioning hole 4 corresponding with the position of blind hole 5, then an end of locating stud 3 is aimed at positioning hole 4 and blind hole 5, by utensil locating stud 3 is directly squeezed in positioning hole 4 and the blind hole 5 again, make locating stud 3 and positioning hole 4 and 5 while of blind hole interference fit by annular knurl 8, need not to carry out respectively the step of twice interference fit, can effectively reduce manufacturing procedure, enhance productivity.
