Abstract
The utility model discloses a piston valve sub -unit with adjustable, including piston, piston valve body, baffle and lock nut, open there is toper through flow opening and is equipped with axial fluid passage on the piston and recover hole and opening, being equipped with among the toper through flow opening and cup jointing coil spring and the adjustable valve block of installing on the piston rod, adjustable valve block is equipped with the multiunit side by side, piston left end face is sealed through overflow valve piece, gasket and the piston valve body who installs on the piston rod, piston right -hand member face through install throttle valve block on the piston rod, restore the valve block and the baffle is sealed, the baffle is fixed through lock nut outward. Toper through flow opening guarantees that adjustable valve block expandes gradually in toper through flow opening when fluid pressure increases, reduce the flow area of liquid, realizes flow area's automatically regulated, comparing traditional piston rod and adjusting, this piston valve has swift, the rapid characteristics of reaction, can provide bigger damping value.
Description
Technical field
The utility model is related to piston valve technical field, more particularly, to a kind of adjustable piston valve sub-unit.
Background technology
Because vehicle is travelled on different road surfaces, the degree of jolting of vehicle body just differs widely.This is accomplished by shock absorber offer
Different damping force value, effectively to buffer jolting for vehicle body, improves the comfortableness and ride comfort of car load.Shock absorber is made in work
During work, as vehicle body jolts the difference of degree, and different damping force value are provided, to the structure design of shock absorber just extremely
It is important.
Utility model content
In order to overcome above-mentioned existing technological deficiency, the purpose of this utility model is to provide one kind as vehicle body jolts
The difference of degree, and different damping force value are provided, to play the adjustable piston valve sub-unit of effective damping effect.
In order to achieve the above object, the utility model is achieved through the following technical solutions：
The technical program is a kind of adjustable piston valve sub-unit, including piston, piston valve body, baffle plate and locking nut；
Taper through flow hole is provided with the piston and axial fluid passage is provided with and restores hole and opening；It is provided with the taper through flow hole
Helical spring on the piston rod and adjustable valve block are installed in socket, and adjustable valve block is provided with side by side multigroup；The piston left side leads to
Cross and the sealing of flow- through valve plate on the piston rod, pad and piston valve body is installed；Piston right side is by installing on the piston rod
Throttle valve plate, recovery valve block and guard seal, are fixed outside baffle plate by lock nut.
When fluid pressure increases, act on the pressure on adjustable valve block and also accordingly increase, adjustable valve block compresses spiral bullet
Spring, helical spring is supported to it makes the gradually deformation expansion in taper through flow hole of adjustable valve block, the just corresponding increase of its area, and by
Gradually cover and restore hole, to reduce the flow area of liquid, realize automatically adjusting for flow area.Flow area reduces, its damping
Force value will accordingly increase, it is achieved thereby that damping automatically adjusting for force value.
Compared with prior art, the beneficial effects of the utility model are：Taper through flow hole is when fluid pressure increases, it is ensured that
Adjustable valve block gradually spreads out in taper through flow hole, reduces the flow area of liquid, realizes automatically adjusting for flow area, through-flow
Area reduces, and its damping force value will accordingly increase, it is achieved thereby that damping automatically adjusting for force value；Multigroup adjustable valve block is in cone
Gradually spread out in shape through flow hole, it is ensured that reduce the through-flow reliability of liquid by changing area, using piston valve
Overall performance is stablized in journey；Compare traditional piston rod to adjust, this piston valve has the characteristics of reacting quick, rapid, can provide
Bigger damping value.
Description of the drawings
The utility model will be illustrated by example and with reference to the appended drawing, wherein：
Fig. 1 is main structure schematic diagram of the present utility model.
Mark in figure：Piston 1, piston valve body 2, baffle plate 3, locking nut 4, taper through flow hole 5, restore hole 6, opening 7,
Helical spring 8, adjustable valve block 9, flow- through valve plate 10, pad 11, throttle valve plate 12 and recovery valve block 13.
Specific embodiment
Below in conjunction with the accompanying drawings, the utility model is described in detail.
In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with accompanying drawing and enforcement
Example, is further elaborated to the utility model.It should be appreciated that specific embodiment described herein is only to explain
The utility model, is not used to limit the utility model.
Embodiment 1, as shown in fig. 1, the utility model is a kind of adjustable piston valve sub-unit, including piston 1, piston
Valve body 2, baffle plate 3 and locking nut 4；Taper through flow hole 5 is provided with the piston 1 and axial fluid passage is provided with and restores the He of hole 6
Opening 7；Socket is provided with the taper through flow hole 5 helical spring 8 on the piston rod and adjustable valve block 9, adjustable valve are installed
Piece 9 is provided with side by side multigroup；The left side of the piston 1 is by installing flow- through valve plate 10 on the piston rod, pad 11 and piston valve
Body 2 is sealed；The right side of piston 1 by installing throttle valve plate 12 on the piston rod, restore valve block 13 and baffle plate 3 is sealed, baffle plate 3
Fixed by lock nut 4 outward.
When fluid pressure increases, act on the pressure on adjustable valve block 9 and also accordingly increase, the compression spiral of adjustable valve block 9
Spring 8, helical spring 8 is supported to it makes the gradually deformation expansion in taper through flow hole 5 of adjustable valve block 9, the just corresponding increasing of its area
Greatly, and gradually cover and restore hole 6, to reduce the flow area of liquid, realize automatically adjusting for flow area.Flow area subtracts
Little, its damping force value will accordingly increase, it is achieved thereby that damping automatically adjusting for force value.The multigroup adjustable valve block being set up in parallel
9, as the increase of pressure gradually spreads out, it is ensured that reduce the through-flow reliability of liquid by changing area, make piston valve exist
Overall performance is stablized during use.The size of flow area is cleverly adjusted with the pressure of liquid, traditional work is compared
Stopper rod is adjusted, and this device has the characteristics of reacting quick, rapid, and the big damping value for providing.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
