Abstract
The utility model relates to a throttle sleeve for steering pumps, and belongs to the technical field of throttle sleeves for steering pumps. The objective to be fulfilled is to provide a throttle sleeve which can adjust and control flow flexibly. According to the throttle sleeve for the steering pump in the technical scheme, external threads are arranged outside a cylinder; a throttle hole is formed inside the cylinder in the axial direction and is a step hole, and one end, which is large in pore diameter, of the step hole has an inner hexagonal structure; and one pump body can be used generally aiming at the steering pumps which have the same appearance and the requirement of different control flows, and the requirement of different control flows can be met by replacing the throttle holes with different pore diameters, so that the generality of the pump body can be improved, the control flows are convenient to adjust during tests, and the situation that conventional pump with different control flows corresponds to multiple pump bodies is changed.
Description
Technical field
A kind of steering pump orifice sleeve of the utility model belongs to steering pump and uses the orifice sleeve technical field.
Background technique
The inner throttle structure of existing motor turning vane pump is directly to process a throttle orifice at pump housing oil outlet place mostly, for the steering pump of identical appearance different flow, changes the control flow rate of steering pump through the size that changes throttle orifice in the pump housing.The big and complex structure of the Pump Body Parts of steering pump, the versatility of the pump housing is just poor like this, and in a single day pump is dressed up the back control flow rate and can't adjust again.
The model utility content
The utility model overcomes the deficiency that existing technology exists, and problem to be solved provides a kind of orifice sleeve that can adjust control flow rate flexibly.
For solving the problems of the technologies described above; The technological scheme that the utility model adopted is: a kind of steering pump orifice sleeve; Cylindrical outside is provided with outside thread, and cylindrical inner shaft is to being provided with throttle orifice, and said throttle orifice is that the big end in step hole and aperture is interior hexagonal structure.
The beneficial effect that the utility model compared with prior art has is: to the steering pump of the different control flow rate requirements of identical appearance; Can general a kind of pump housing; The utility model through changing different throttle orifices aperture satisfies the Different control traffic requirement, can improve the versatility of the pump housing.During convenient simultaneously test to the adjustment of control flow rate.Changed the pump of different control flow rate in the past, the situation of the corresponding multiple pump housing.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the plan view of Fig. 1.
Fig. 3 is the installation diagram of the utility model.
Among the figure, 1 is cylindrical body, and 2 is throttle orifice, and 3 is the steering pump pump housing.
Embodiment
Like Fig. 1, Fig. 2, shown in Figure 3, a kind of steering pump orifice sleeve of the utility model: the outside of cylindrical body 1 is provided with outside thread, and the inner shaft of cylindrical body 1 is to being provided with throttle orifice 2, and said throttle orifice 2 is interior hexagonal structure for the big end of step hole and aperture.
It is identical that the utility model can be made a series of external diameters, the assembly that internal diameter is different, and the interior hexagonal structure of throttle orifice 2 can be packed the utility model in the oil outlet of the steering pump pump housing 3 easily in the utility model.
The working procedure of the utility model is: the oil outlet place of the steering pump pump housing 3 is processed with the internal thread with the outside thread of the utility model coupling; Directly the utility model is screwed in the oil outlet internal thread of the steering pump pump housing 3; When needs were adjusted the control flow rate of the steering pump pump housing 3, the utility model of directly being replaced by different throttle orifices 2 apertures got final product.
Claims (1)
1. steering pump orifice sleeve, it is characterized in that: the outside of cylindrical body (1) is provided with outside thread, and the inner shaft of cylindrical body (1) is to being provided with throttle orifice (2), and said throttle orifice (2) is interior hexagonal structure for the big end of step hole and aperture.
