Novel protected range.
It is in the description of the present invention, it should be noted that term " center ", "upper", "lower", "left", "right", " perpendicular
Directly ", the orientation or positional relationship of the instructions such as "horizontal", "inner", "outside" is to be based on the orientation or positional relationship shown in the drawings, and is only
For ease of description the utility model and simplify description, rather than the device or element of indication or suggestion meaning must have it is specific
Orientation, be constructed and operated in a specific orientation, therefore should not be understood as limiting the present invention.In addition, term " the
One ", " second ", " third " are used for descriptive purposes only and cannot be understood as indicating or suggesting relative importance.
In addition, as long as technical characteristic involved in the utility model different embodiments disclosed below is each other
Not constituting conflict can be combined with each other.
Fig. 1 is the central cross-sectional view according to the mechanical two-port valve of this practical preferred embodiment；Fig. 2 is amplified at A in Fig. 1
Figure.Mechanical two-port valve generally may include valve body 1, spool 2, spring 3, and pushing block 4 is preferably arranged.
Such as Fig. 1, valve body 1 is bulk, is provided with oil duct 11 in valve body 1, the side of oil duct 11 is provided with a separately spacing
From first opening 111 and second opening 112.It generally is passed through hydraulic oil from the first opening 111, from the second 112 effluxes of opening
Pressure oil.Connection or blocking between spool 2 and the control of spring 3 first opening 111 and the second opening 112.
Such as Fig. 1 and such as Fig. 2, the oil duct between the first opening 111 and the second opening 112 is provided with contraction flow region 113.This reality
Apply in example, contraction flow region 113 be it is step-like, on direction from left to right, the internal diameter of oil duct 11 reduces suddenly to be formd step and receives
Contracting portion 113.
At the second opening 112, the left end of spool 2 extends to the first opening 111 and crosses contraction flow region 113 setting of spool 2
It is connected with the right end of spring 3.The part that spool 2 crosses contraction flow region 113 is formed with one week protrusion 21, and protrusion 21 has towards receipts
The inclined-plane 211(in contracting portion 113 is referring to fig. 2).
When protrusion 21 is in contact with contraction flow region 113, be formed as sealing state between protrusion 21 and contraction flow region 113, specifically
Be to be formed as cone sealing between inclined-plane 211 and contraction flow region 113, not phase between the first opening 111 and the second opening 112 at this time
Logical, hydraulic oil cannot be communicated to the second opening 112 from the first opening 111.
(spool 2 is pushed to the left) when protrusion 21 is separated with 113 phase of contraction flow region, formed between protrusion 21 and contraction flow region 113
For discrete state, be particularly formed as discrete state between inclined-plane 211 and contraction flow region 113, at this time the first opening 111 and second
It is connected between opening 112, hydraulic oil is connected to the second opening 112 from the first opening 111.
In other technical solutions, inclined-plane 211, such as setting arcwall face and the perpendicular face of axial line can also be not provided with
Deng.
In other technical solutions, contraction flow region 113 can not also be as described above from first opening 111 to second opening 112
Upper 11 internal diameter of oil duct reduces to be formed, for example only the internal diameter at contraction flow region 113 reduces, except the oil duct of 113 other parts of contraction flow region
Oil duct internal diameter at 11 (at the first opening 111 and the second opening 112) is all larger than 113 minimum diameter of contraction flow region.
In other technical solutions, contraction flow region 113 can not also be step-like, for example be chevron protrusion, and self-constriction portion 113 is most
Small inner radius is gradually reduced to 113 internal diameter of contraction flow region of two sides.
Such as Fig. 1, the other end of spool 2 is arranged in 4 left end of pushing block.4 slip of pushing block is arranged in valve body 1, to make valve
2 right end slip of core is arranged in valve body 1.
It is mutually sealed between the circumferential surface of pushing block 4 and valve body 1, to prevent hydraulic oil in oil duct 11 from leaking out.
The right end of pushing block 4 exposes valve body 1, and the part that pushing block 4 exposes valve body 1 is formed as pushing part 41, makes it easier to push away
Dynamic pushing block 4 is to push spool 2.
Such as Fig. 1, sprue 12 is additionally provided in valve body 1, sprue 12 extends to oil duct 11, and the left end of spring 3 is fixed on sprue
On 12.The setting of sprue 12 is so that the manufacture and assembling of mechanical two-port valve are more easy.
The above embodiments are only for explaining the technical ideas and features of the present invention, and its object is to allow be familiar with technique
Personage can understand the content of the utility model and implement accordingly, do not limit the protection scope of the present invention,
All equivalent change or modifications according to made by the spirit of the present invention essence, should all cover the protection scope of the utility model it
It is interior.
