Description
Technical field
The present invention relates to a kind of high-power vibration damping valve arrangement, belong to hydraulic system and road vehicle application field.
Background technology
The effect of liquid-springing valve is exactly back and forth to be flowed in damping hole by liquid, due between liquid internal molecule with
And the friction between molecule and hole wall, convert vibrational energy into heat energy and distribute, so that the vibration of vehicle of decaying.Civilian goods car
Damping unit damper valve generally use choke valve slice structure, form is simple and with certain versatility, but practice have shown that
Then insufficient strength is applied on motor-driven off-road vehicle high, valve block fracture often occur causes the situation of failure of apparatus.In addition at present
The liquid-springing valve generally existing overall volume of the manufacturing is larger, and construction is complicated, the defect such as quality is unstable.It is contemplated that
There is provided a kind of with earial drainage function and liquid-springing valve simple and reliable for structure is solving above-mentioned technical problem.
The content of the invention
The present invention provides a kind of liquid-springing valve, it include valve body, adjusting pad, spring base, helical spring, valve element, valve seat,
Baffle ring and circlip for hole.Wherein, adjusting pad is installed in valve body, and spring base is close to adjusting pad placement, and helical spring is supported
Lean against on spring base, valve element loads in the through hole of valve body, in the hole of its bar portion insertion spring base.Valve seat is connected with valve body screw thread,
Valve element is pressed on helical spring by tightening valve seat.The conical surface of valve seat and the conical surface of valve element complement each other to form conical surface seal.
Valve seat is provided with centre bore and circumferential uniform throttle orifice.Baffle ring is between valve seat and circlip for hole.Valve element is provided with
Normal open hole and the throttle orifice being evenly distributed.
Wherein valve body plays the fixation and guide effect of other parts.Valve seat is provided with centre bore with circumferential uniform section
Discharge orifice, centre bore is the oil duct of positive revesal, and circumferential uniform throttle orifice is engaged the oil duct for being only used for revesal with baffle ring.Valve
Also two kinds of throttle orifices i.e. normal open hole and throttle orifice is designed on core, two kinds of oilholes are functioned both on during revesal, fluid during compression travel
Flow velocity be less than certain value when, fluid flows only through low pressure oil duct, when fluid flow velocity exceed certain particular value when, valve element overcomes spiral
The spring force that spring is provided, another oil duct is opened, such that it is able to realize, the different damping force of positive revesal, and can protect
, in positive stroke, resistance rises will not be too fast, the speed that resistance rises for card, can be adjusted by adjusting the power of helical spring
It is whole.
Liquid-springing valve provided by the present invention solves above-mentioned the deficiencies in the prior art well, stable and reliable in work,
The damping capacity of hydro-pneumatic spring can be effectively improved by facts have proved.

Specific embodiment
The invention will be further described with reference to the accompanying drawings and examples.
Liquid-springing valve small volume of the present invention, it is lightweight, it is stable and reliable in work.It include valve body 1, adjusting pad 2,
Spring base 3, helical spring 4, valve element 5, valve seat 6, baffle ring 7 and circlip for hole 8.
Adjusting pad 2 is installed in valve body 1, and spring base 3 is close to adjusting pad 2 and is placed, and helical spring 4 is resisted against on spring base 3,
Valve element 5 loads in the through hole of valve body 1, in the hole 10 of its bar portion 11 insertion spring base 3, is oriented to using hole 10.In assembling, first
Selected adjusting pad 2 is put into valve body 1, spring base 3 is then placed in, spring base 3 coordinates with the gap of 1 endoporus of valve body 9, to ensure
Easily spring base 3 can be put into valve body 1, be then placed in helical spring 4, reinstall valve element 5.Valve seat 6 connects with the screw thread of valve body 1
Connect, valve element 5 is pressed on helical spring 4 by tightening valve seat 6.The conical surface 15 of valve seat 6 and the mutual cooperation shape of the conical surface 14 of valve element 5
Into conical surface seal, while two conical surfaces also have certain positioning and guiding to act on.Valve seat 6 is provided with centre bore 16 and circumferential uniform section
Discharge orifice 17.Between valve seat 6 and circlip for hole 8, the effect of back-up ring 8 is that anti-baffle ring 7 takes off from damper valve to baffle ring 7
Go out.During damper valve works, valve element 5 axially moves in the presence of fluid along the hole 10 of spring base 3, in valve element
There are normal open hole 12 and throttle orifice 13 on 5, throttle orifice 13 is evenly distributed.
Fig. 5 is work sheet of the damper valve in compression travel, and Fig. 6 is that damper valve is restoring the work sheet (arrow in figure of stroke
Represent the direction of liquid stream).
During compression travel, as shown in figure 5, fluid is by the right side of valve body 1 flow direction left side.Baffle ring 7 is uniform by the circumference of valve seat 6
Normal open hole 17 is blocked, and the compressed throttle orifice 12 of centre bore that fluid then flows through valve element 5 by the centre bore 16 of valve seat 6 enters into valve body
Left side.When piston speed increases, the flow velocity of fluid increases, when fluid speed reaches to a certain degree, produced by orifice valve
When throttle resistance pressure difference exceedes the pretightning force of helical spring 4, it is relative that valve element 5 will overcome the effect of helical spring 4 and valve body 1 to occur
Motion, can produce current by pass between its conical surface 14 and valve seat 6, i.e., can be divided into two again by the fluid of valve base center hole 16
Road, leads up to the throttling of compression throttling hole 12 and enters shoe cream room, and another road then enters shoe cream room by current by pass earial drainage, also
It is to say, can be decreased obviously by the flow in compression throttling hole 12, increases too fast with speed so as to reach suppression shock absorber Resistance Value
Purpose.
When restoring stroke, as shown in fig. 6, fluid is by the left side of valve body 1 flow direction right side.Answered in the effect valve element 5 of helical spring 4
Position, i.e., the conical surface 14 of valve element 5 is close together with the conical surface 15 of valve seat 6.Now baffle ring 7 moves right to circlip for hole 8,
Restore throttle orifice 17 and be in opening state, fluid point two-way flows to the right side of valve body, and a part of fluid order is saved by compressing
Discharge orifice 12 and valve base center hole 16 enter valve body right side, another part then order by circumferential uniform hole 13 on valve element 6 and multiple
Former throttle orifice 17 enters valve body right side.
Liquid-springing valve in the present invention uses cone valve type linear sealing structure, to the sensitiveness of impurity pollution in fluid
Small, easy to manufacture, sealing property is excellent, with good promotional value.
It should be noted that skilled person can easily appreciate that, liquid-springing valve involved in the present invention can
It is installed as described above on different types of vehicle, and do not departing from the spirit of the invention that is defined by the following claims
In the case of scope, the change and change of various multi-forms can be carried out to the present invention.
