Specific embodiment
The utility model embodiment is described further with reference to the accompanying drawing:
As shown in Figure 1, a kind of plug-in one-way valve with guide hole, including valve seat 1, cover board 2 and spool 3, the valve
Seat 1 and cover board 2 complement each other to form accommodating cavity 4, and the spool 3 is set in accommodating cavity 4 and accommodating cavity 4 is separated into control chamber
41 and oil suction chamber 42, the valve seat 1 is equipped with oil inlet 11 and oil outlet 12, is equipped with elastic component 5 in the control chamber 41,
The spool 3 have close so that first position that oil inlet 11 and oil outlet 12 are isolated and open so that oil inlet 11 and
The second position that oil outlet 12 is connected, the spool 3 are equipped with guide hole 31, and the guide hole 31 passes through oil suction chamber 42
It is connected with oil outlet 12.The guide hole 31 is angularly disposed.Guide hole is provided on the utility model spool, so that
The path that oil liquid passes through is shorter, and liquid resistance is smaller, substantially reduces the closing time of spool, while structure is simple, easy to process, no
It needs additionally to valve deck, other component, processed to main valve, check valve is small in size, does not change original inserted valve installation ruler
It is very little.When inlet pressure oil does not input, inlet pressure is reduced, and the pressure oil of oil outlet enters control chamber by guide hole,
Under high pressure effect, so that spool quick closedown, cutting oil liquid is flowed from oil inlet to oil outlet.
The spool 3 is equipped with spring cavity 32, and the spring cavity 32 is connected with control chamber 41, the spring cavity
32 are connected by the guide hole 31 on spool 3 with oil suction chamber 42, oil outlet 12.Specifically, one end of the elastic component 5 is inserted
Enter and offset in spring cavity 32 with spool 3, the other end offsets with cover board 2, and there is the elastic component 5 driving spool 3 to tend to first
The movement tendency of position.The setting of spring cavity plays the role of limition orientation to elastic component, resets convenient for elastic component, is convenient for simultaneously
Spool is reliably closed.
The spool 3 include fit with valve seat 1 for 1 oil inlet 11 of seal valve seat sealing 33 and be used for and valve
The guide part 34 that 1 inner wall of seat fits, the diameter of 34 outer surface of guide part are greater than the diameter of 33 outer surface of sealing.In this way
Structure make valve core structure simple, easy to assembly, movement is steady reliable.
Interconnecting piece 35 is equipped between the guide part 34 and sealing 33, the guide hole 31 is set to interconnecting piece 35
On.Specifically, the arc-shaped setting of interconnecting piece 35.Such infrastructure product is easy to process, and structure is simple, and sealing can
It leans on.
The guide hole 31 is disposed in proximity on the spool 3 of 33 one end of sealing.Such structure makes spool and draws
Guide hole processing is convenient, and the path that spool guide hole flows through is shorter, and spool closing speed is faster.
The sealing 33 of spool 3 fits with 1 inner wall of valve seat at oil inlet 11 when the spool 3 is in first position
Form inclined-plane sealing pair 36.Such structure makes product sealed reliable.
