Outer circumference surface coincide, and two short straight flanges are connected in the two ends of long straight flange respectively, and two middle straight flanges are connected to long straight flange both sides
On short straight flange, arc-shaped edges two ends line constitutes a flat polygon, long straight flange and its both sides with long straight flange, short straight flange and middle straight flange
Short straight flange and the outer of middle straight flange be respectively equipped with wide side plate, narrow side and the latus inframedium extending downwardly, above-mentioned width side plate, narrow side
Plate and latus inframedium are sequentially connected with, and form a housing that inner side is uncovered, downside is uncovered with top board, and two latus inframediums and top board
On have U-lag mouth, the opening of the U-lag mouth on top board is located at arc-shaped edges, and the U-lag mouth on latus inframedium is vertically arranged,
And its opening is located in the lower edge of latus inframedium, top board lower surface is additionally provided with a downward damping projection, damping projection main body
Square shaped, its medial surface is the interior concaved circular cambered surface identical with the outer circumference surface of adapted column, and housing is by polyurethane foam plastics
Make, described damping projection is made up of microcellular polyurethane elastomer, the width of U-lag mouth is more than the external diameter of adapted high-pressure rubber pipe.
, referring to CN 101191010 B, microcellular polyurethane elastomer is referring to CN 1146608 C for polyurethane foam plastics.
During use, this flexible legs hydraulic control one-way valve and relief valve preventer are covered on the column pilot operated check valve of adapted
And so as to high-pressure rubber pipe is respectively embedded in a U-lag mouth on relief valve, described damping projection is pressed in the column hydraulic control list of adapted
To on valve and relief valve.It is so designed that, falling rocks or coal breakage are pounded on this flexible legs hydraulic control one-way valve and relief valve preventer,
Column pilot operated check valve and relief valve will not be damaged, be not easy to the staff that damages.
As optimization, two latus inframediums are respectively equipped with fixed via, fixed via is located inside U-lag mouth.So set
Meter, this flexible legs hydraulic control one-way valve and relief valve preventer can be fixed by the bolt or screw that are located in fixed via.
This utility model flexible legs hydraulic control one-way valve and relief valve preventer have structure simply, and protection, is torn open comprehensively
Fill convenient advantage, suitable mine hydraulic prop uses.
