Valve body 9, acceleration valve rod chamber spring 10, acceleration valve rod chamber check valve 11 and acceleration valve rod chamber one-way valve seat 12.
The order valve body 5 is have the hole of left and right two, inside to have one from the horizontal of left surface upper shed on the wall of side
The structure of long cavity, described two hole difference A mouths and B mouths, two Kong Junyu laterally long cavity connections, the sequence valve adjusts spiral shell
2, sequence valve adjustment spring 3 is blocked up in the adjustment of silk 1, sequence valve and order valve core 4 (is defined) by accompanying drawing orientation pacifies successively from left to right
Horizontal long cavity inside is mounted in, wherein sequence valve adjustment screw 1 one end is located in horizontal long cavity, and the other end is located at horizontal vast sky
Chamber outside.
The order valve core 4 is equipped with the construction of four sections of strips of growing crosswise of an indent notch for the centre bit of left end face,
First paragraph wherein from left to right, the 3rd section of longitudinal cross-section are equal with the longitudinal cross-section of horizontal long cavity, and second segment and the
Four sections of longitudinal cross-section is less than the longitudinal cross-section of horizontal long cavity, and four sections of cross central line overlaps；Sequence valve adjusts spring 3 one
End contacts with sequence valve adjustment stifled 2, and the other end is located in the indent notch in the left end face of order valve core 4, when without outer
During the effect of power, sequence valve adjustment spring 3 withstands order valve core 4, and now the first paragraph of order valve core 4 withstands sequence valve valve
The hole (A mouths) of the upper left side of body 5, its second segment is located at the lower section in the hole (B mouths) on right side on order valve body 5；Promote when there is external force
Order valve core 4 to the left compression sequence valve adjustment spring 3 when, the second segment of order valve core 4 moves to left on order valve body 5
Hole (A mouths) lower section of side, now the hole (A mouths) of the left and right sides connects with (B mouths) on order valve body 5.
Forward and backward, six sides in upper and lower, left and right Shang Junyou holes the structure of the acceleration valve body 9, wherein left and right side
There are a hole, the hole on left surface and the hole lateral direction penetrating on right flank on face, the centre position and its right side of upper side is equal
There is a hole, there is a hole at the left and right two ends that there is a hole, leading flank in the centre position and its left side of downside (respectively
For Ch mouths, Vr mouths), there is a hole (Ch1 mouths) trailing flank lower right, the Kong Junyu left and right sides phase on forward and backward, upper and lower side
The hole of insertion connects, and the hole (A1 mouths) in the centre position of upper side is longitudinally passed through with the hole (Cr mouths) in the centre position of downside
It is logical.Two holes (A1 mouths, B1 mouths) on the upper side connect respectively with two holes (A1 mouths, B1 mouths) on order valve body 5
And link together.
The acceleration valve rodless cavity spring capping 6, acceleration valve rodless cavity spring 7 and acceleration valve rodless cavity check valve 8 are from a left side
It is sequentially arranged to the right side in the cross through hole for accelerating the left end of valve body 9 and (accelerates the hole of the left and right side lateral direction penetrating of valve body 9),
Acceleration valve rod chamber spring 10, acceleration valve rod chamber check valve 11 and acceleration valve rod chamber one-way valve seat 12 are pacified successively from left to right
It is mounted in the cross through hole for accelerating the right-hand member of valve body 9, and the hole in the centre position of the hole in the centre position of upper side and downside
It is longitudinally through.When in the raw, acceleration valve rodless cavity spring 7 withstands acceleration valve rodless cavity check valve 8, and acceleration valve has bar
Chamber spring 10 withstands acceleration valve rod chamber check valve 11, makes on the right side of hole and the acceleration valve rod chamber check valve 11 on the left of downside
Cross through hole part does not connect with the mid portion of cross through hole；When acceleration valve rodless cavity check valve 8 to the left compression acceleration valve without
Rod cavity spring 7, the compression acceleration valve rod chamber spring 10 to the left of acceleration valve rod chamber check valve 11, at above-mentioned two through hole with it is laterally logical
The mid portion connection in hole.
The oil cylinder acceleration valve is directly mounted at the afterbody of hydraulic tongs oil cylinder, has both saved the connection of outside oil circuit, increases again
Acceleration valve is controlled the smart of oil cylinder.The Ch1 mouths connection corresponding with the rodless cavity of oil cylinder of acceleration valve.Cr mouths pass through exterior tube
Road is connected with the rod chamber of oil cylinder.Ch mouths are connected with the Aw mouths of excavator distributor.Vr mouths connect with the Bw mouths of excavator distributor
Connect.The A1 mouths and Cr mouths for accelerating valve body leads directly to, and B1 mouths lead directly to Vr mouths.
When hydraulic tongs works, come oily from Aw mouths, the Ch mouths of acceleration valve are direct-connected with the rodless cavity of oil cylinder with Ch1 mouths, hydraulic pressure
Oil enters oil cylinder rodless cavity and promotes cylinder rod to overhanging.The hydraulic oil of rod chamber connects through the Cr mouths of exterior line and acceleration valve
Connect, enter into acceleration valve.Order valve core 4 under nature is because the thrust that sequence valve adjusts spring keeps sequence valve A mouths and B
Between be close, hydraulic fluid pressure raise push acceleration valve rodless cavity check valve 8 open, with the liquid from excavator distributor Aw mouths
Force feed, jointly into the rodless cavity of oil cylinder, realizes the quick motion of cylinder rod by Ch1 mouths.
When the crushed thing of hydraulic pressure clamp, to overhanging by resistance, the pressure rise of rodless cavity, hydraulic oil passes through cylinder rod
Acceleration valve internal galleries come side of the order valve core 4 without spring, overcome the thrust promotion order valve element of spring to there is bullet
One lateral movement of spring is so as to getting through the A mouths and B mouths of sequence valve.Now the hydraulic oil of rod chamber passes through the accelerated valve Vr mouths of sequence valve
It is back to excavator Bw mouths and returns to fuel tank.Now the oil pressure of excavator can completely act on rodless cavity, make oil cylinder play maximum
Thrust.So as to hydraulic tongs is easily caught broken crushed thing.
The next oily Jing Vr mouths of the Bw mouths of excavator push rod chamber check valve 11 open and come Cr mouths.Simultaneously the hydraulic oil Jing of Vr mouths adds
The internal galleries of fast valve body 9 come the side of acceleration valve rodless cavity spring 7 of acceleration valve rodless cavity check valve 8.Because check valve both sides
Difference in areas along with acceleration valve rodless cavity spring 7 thrust so check valve is to be closed.Hydraulic oil enters oil cylinder
Rod chamber make cylinder rod to bouncing back back.
The utility model oil cylinder acceleration valve is secondary using the acceleration purpose for realizing oil cylinder, institute using the hydraulic oil of rod chamber
So that through upgrading oil cylinder piston rodless cavity side and the difference in areas of rod chamber side, the speed of service raising 33% of oil cylinder can be made, and then
The operating efficiency for making hydraulic tongs improves 30% to 40%.
The announcement and teaching of book according to the above description, the utility model those skilled in the art can also be to above-mentioned reality
The mode of applying is changed and changed.Therefore, the utility model is not limited to specific embodiment disclosed and described above, right
Some modifications and changes of the present utility model should also be as falling in scope of the claims of the present utility model.Additionally, to the greatest extent
Some specific terms used in pipe this specification, but these terms are merely for convenience of description, not to the utility model
Constitute any restriction.
