It is fixed on T type grooves pedestal 15；Sliding bearing 4, holder 9, tank support 11 constitute support system；Valve system 10 is for controlling
The flow direction of fluid, including flowing valve and rebuilt valve, flowing valve is by flow- through valve plate 38, cone shaped spring tabletting 37, tune
Whole gasket a36 compositions；Rebuilt valve is by recovery valve block 41, recovery throttle valve plate 42, cylindrical spring 44, adjust pad b 43, valve seat
45 equal compositions, nut 46, which is used for fixed valve base 45, prevents sliding in an axial direction.
The flow- through valve plate 38 should have certain flatness with valve block 41 is restored.
The dust seal 6, the sealed diameter of oil sealing 7 are identical.
The operation principle of the utility model is：
By toggle the reciprocating motion that the convert rotational motion of motor shaft is piston rod, to ensure that crank exists
It can be passed through when moving to highest, low spot, the length of connecting rod should be greater than the distance between two centre of gyration of crank.
Test the operation principle of deck valve system：There are two types of working conditions for testing stand, first, piston rod is in compression travel, it is another
Kind is that piston rod is in extension stroke.When piston rod 8 is in compression travel, piston 40 moves right at this time, 40 right chamber of piston
The volume of room reduces, and oil pressure increases, when pressure increase to a certain extent when flowing valve open, fluid is by the damping hole on piston 40
Flow to the left chamber of piston 40, but since right chamber by piston rod 8 accounts for a part of volume, thus the increased volume of left chamber is less than right chamber
The volume of reduction, a part of fluid just flow back to repairing chamber 12；When piston rod 8 is in extension stroke, piston 40 is to moving to left at this time
Dynamic, 40 left chamber volume of piston reduces oil pressure and increases, and flowing valve is closed, and the fluid in left chamber will pass through damping hole on piston and push open again
Former valve flow right chamber, since the fluid that the presence of piston rod 8 comes from left chamber is not enough to be full of the increased volume of right chamber, repairing chamber 12
It will be toward right chamber makeup oil liquid.
The operation principle of rebuilt valve：Notched recovery valve block 41 is pressed on piston, when the pressure for restoring 41 both ends of valve block
When difference is smaller, oil pressure can not be such that rebuilt valve opens, so fluid can only be flowed out by the normal open mouth on piston 40, the resistance of generation
It is larger；When both ends pressure difference is larger, oil pressure so that restoring valve block is deformed, and increases the aperture for restoring valve block 41, so oily
The flow area of liquid increases damping force and reduces instead.
The operation principle of flowing valve：The effect of flowing valve is to ensure the one-way flow of fluid, i.e., only allows axis in compressed line
Journey mesohigh chamber fluid flows into low pressure chamber.Only when high pressure chest fluid is more than the pre- of cone shaped spring tabletting 37 to the pressure of valve block
When the deformation force of clamp force or valve block 38, flow- through valve plate 38 could open, due to the pretightning force very little of cone shaped spring tabletting 37, when
When flow- through valve plate 38 fully opens, circulation area be on piston 40 6 damping holes plus 6 normal open mouths same flow area it
With, they generate jointly damping force rise throttling action.
It is mainly made of dynamical system, kinematic system, support system, measuring system etc. with reference to attached drawing the utility model.It is dynamic
Force system is provided by motor 1, and motor 1 is speed regulating motor, and the movement velocity of piston rod is controlled by adjusting the size of rotating speed.
Kinematic system is made of crank 3, connecting rod 23, monaural ring 24, piston rod 8, and wherein crank, connecting rod, monaural ring are constituted
Toggle is converted into the circular motion of motor shaft by it the linear motion of piston rod.
