Beneficial effect is：Only need to heat rotation stop keyway, without being heated to whole rotation stop pilot hole, make itself and axle
Bar, which is formed, to be coordinated, and saves the time.
The technical scheme of valve of the utility model with gear shaft is：A kind of valve, including valve casing, gear is installed on valve casing
Axle, the gear, which has, to be used in expanded by heating for axostylus axostyle insertion, the rotation stop pilot hole in normal temperature with axostylus axostyle tight fit.
Beneficial effect is：By hot matching method, gear and axle are assembled using metal heat-expansion shrinkage principle, realized
Gear is removable after being assembled with axle, and then realizes when a gear failure, it is only necessary to which more gear changing, axostylus axostyle have obtained rationally
Utilize, furthermore achieved that the reasonable utilization of resource, reduce production cost.
The valve is orifice valve.
Beneficial effect is：By in chamber indoor location restricting orifice, realizing that natural gas throttles.
The rotation stop pilot hole is the circular hole that inwall is provided with rotation stop groove, the outer circumferential surface of the axostylus axostyle be provided be used for
The rotation stop convex key of rotation stop keyway adaptation.
Beneficial effect is：Prevent axostylus axostyle from being rotated in pilot hole inner circumferential.
The gear is interference fitted with axostylus axostyle in normal temperature by rotation stop groove and rotation stop convex key.
Beneficial effect is：Only need to heat rotation stop groove, without being heated to whole rotation stop pilot hole, make itself and axle
Bar, which is formed, to be coordinated, and saves the time.

Embodiment
Embodiment of the present utility model is described further below in conjunction with the accompanying drawings.
The embodiment of gear shaft of the present utility model, as shown in Figure 1 to Figure 2, by two gears 1 and an axostylus axostyle
3 compositions.For the structure of gear 1 as shown in figure 3, the internal diameter of gear 1 carries rotation stop groove 2, gear 1 is interior to carry rotation stop pilot hole 5.Axostylus axostyle
3 structure solid cylinder of the both ends with rotation stop convex key 4 as shown in figure 4, be made up of.The rotation stop groove 2 of gear 1 and axostylus axostyle 3
Rotation stop convex key 4 using interference fit, utilize metal heat-expansion shrinkage principle assembling, i.e., after being heated to 80-100 DEG C to gear 1, tooth
1 expanded by heating is taken turns, the internal diameter size of gear 1 is more than the outside dimension of axostylus axostyle 3, and the size of rotation stop groove is more than the size of rotation stop convex key,
Axostylus axostyle 3 is inserted to the rotation stop pilot hole 1 of gear 1, the rotation stop groove 2 of gear 1 and the rotation stop convex key of axostylus axostyle 3 are realized after being down to normal temperature
