Description of the drawings:
FIG. 1 is a schematic diagram of a damping device with a fixed structure.
The figures are numbered: 101. the valve comprises a valve rod 10101, a valve block 102, a sealing ring 103, a shell 104, damping liquid 105, an inner shell plate 106, a plunger rod 107, a motor head assembly 108, an electric wire 109, a first connecting hole 110, a second connecting hole 111, a first shell cavity 112, a second shell cavity 11201 and a sub-cavity.
The specific implementation mode is as follows:
the present invention will be described in detail below with reference to the accompanying drawings.
As shown in fig. 1, a damping device with a fixed structure comprises a housing 103 and a valve rod 101, wherein the valve rod 101 penetrates through the housing 103, and the valve rod 101 and the housing 103 are in sliding sealing fit together, the damping device further comprises an inner shell plate 105, a plunger rod 106 and a motor head assembly 107, the inner shell plate 105 is arranged in the housing 103, the inner shell plate 105 divides the space in the housing 103 into a first shell cavity 111 and a second shell cavity 112 which are independent and communicated, one end of the valve rod 101 is in sliding sealing fit with the second shell cavity 112, the second shell cavity 112 is divided into two independent and volume-variable sub-cavities 11201 by the valve rod 101, a plug hole is formed in the housing 103, the plunger rod 106 is directly or indirectly in sliding sealing fit on the plug hole, the motor head assembly 107 is arranged on the outer wall of the housing 103, and the motor head assembly 107 is used for driving the plunger; when the plunger rod 106 is located in the first housing cavity 111, the plunger rod 106 divides the first housing cavity 111 into two separate compartments. The power head assembly 107 is connected to a power line 108 for supplying power to the power head assembly 107.
Compared with a traditional liquid medium damping rod, in the device, an inner shell plate 105 is arranged in a shell 103, the inner space of the shell 103 is divided into a first shell cavity 111 and a second shell cavity 112 which are independent and communicated, one end of a valve rod 101 is matched with the cavity wall of the second shell cavity 112 in a sliding and sealing mode, convection of damping liquid 104 on two sides of the valve rod 101 is achieved through the first shell cavity 111, a plunger rod 106 can cut off or communicate the first shell cavity 111 through self movement, when the first shell cavity 111 is cut off, liquid on two sides of the valve rod 101 cannot be subjected to convection, the valve rod 101 cannot move continuously, when the plunger rod 106 moves again and breaks through the first shell cavity 111 and the second shell cavity 112 again, the damping liquid 104 on two sides of the valve rod 101 can be subjected to convection again, and the valve rod 101 can move again.
Referring to fig. 1, it is further stated that when the plunger rod 106 does not block the first housing chamber 111, there is a limit to the rightward movement of the valve stem 101 (i.e., there is a limit to the compression), because when the valve stem 101 is moving rightward, the damping fluid in the right-side sub-chamber 11201 flows into the left-side sub-chamber 11201, but the volume of the valve stem 101 entering the housing 103 increases, causing squeezing (compression of the damping fluid) of the damping fluid in the housing 103, and because there is a limit to the compression of the damping fluid, there is a limit to the rightward movement of the valve stem 101. Similarly, when the plunger rod 106 separates the first housing cavity 111 and the valve rod 101 moves rightwards again, the damping liquid in the right sub-cavity 11201 cannot flow but is compressed by a part, and at this time, the valve rod 101 moves rightwards for a part of distance but cannot move rightwards continuously; similarly, when the valve stem 101 moves to the left, it cannot move further to the left because of the negative pressure in the left sub-chamber 11201.
The device divides the interior of the shell 103 into two independent and communicated first shell cavity 111 and second shell cavity 112 through the arrangement of the inner shell plate 105, and controls the on-off of the damping liquid 104 on two sides of the valve rod 101 by the movement of the plunger rod 106, thereby realizing the dual functions of buffering and supporting and realizing convenient and rapid conversion.
As shown in fig. 1, a valve block 10101 is disposed on a section of the valve stem 101, and the valve block 10101 is slidably and sealingly engaged with the housing 103 and the inner shell 105.
Valve block 10101 is a portion of valve stem 101 that is well known in the art.
As shown in fig. 1, the housing 103 is provided with a seal ring 102, and the seal ring 102 is used to seal a gap between the housing 103 and the valve stem 101.
As shown in fig. 1, seal ring 102 is located within housing 103.
The function of the sealing ring 102 is to prevent leakage between the valve stem 101 and the housing 103.
As shown in fig. 1, a first connection hole 109 is formed in the valve rod 101, a second connection hole 110 is formed in the housing 103, and the first connection hole 109 and the second connection hole 110 are both located outside the housing 103.
As shown in fig. 1, the power head assembly 107 is sealingly disposed in the plug hole, the plunger rod 106 is mounted on the power head assembly 107, and the power head assembly 107 is used for driving the plunger rod 106 to move.
The movement of the plunger rod 106 on the housing 103 can be realized in various manners, and the movement of the plunger rod 106 between the plunger rod 106 and the motor head assembly 107 can be realized through electromagnetic control, and can also be realized through motor pushing or air cylinder pushing.
As shown in fig. 1, the first shell cavity 111 and the second shell cavity 112 are filled with the damping liquid 104.
The above description is only for the preferred embodiment of the present invention and is not intended to limit the scope of the present invention, and all equivalent structural changes made by using the contents of the present specification and the drawings can be directly or indirectly applied to other related technical fields and are included in the scope of the present invention.
