Summary of the invention
The purpose of this utility model is to provide a kind of high-temperature steam to help pass valve packing gland withdrawing device, this withdrawing device simple in construction, it is capable of the most vertically going up uniformly dynamics dismounting column type packing gland, substitute original that relative clumsy, laborious, violence formula dismounting column type packing gland, while alleviating the labor intensity of maintainer and difficulty, complete packing replacing work.
Realize the technical scheme of this utility model purpose: a kind of high-temperature steam helps pass valve packing gland withdrawing device, this device includes positioner, locking device and adjustment bolt, positioner includes left positioner and right positioner, left positioner and right positioner are connected by locking device, being provided with a boss inside left positioner, right positioner, two boss dock ringwise.
Described left positioner and right positioner are all in semi-circular cylindrical, and left positioner and right positioner form cylindric positioner by locking device fastening.
The inside middle portion of described left positioner is provided with the left boss of semi-circular shape, and right positioner inside middle portion is provided with the right boss of semi-circular shape, left boss and the docking of right boss and forms annulus.
Described locking device includes two groups of location nut, hangers, bolts, a location nut it is respectively provided with outside the two side up and down of left positioner, a hangers it is respectively provided with outside the two side up and down of right positioner, often being connected each via a bolt is fixing between group location nut and hangers, left positioner and right positioner are fastened and form positioner by location nut, hangers, bolt.
It is respectively provided with one in the middle of two location nuts on described left positioner, right positioner and adjusts bolt.
Advantageous Effects of the present utility model: (1) gland of the present utility model withdrawing device is capable of locking column type packing gland quick, effective so that it is will not slip in disassembly process；(2) gland withdrawing device of the present utility model ensure that with the uniform strength of surrounding, and dismounting column type gland in the vertical direction, greatly reduces because unbalance stress causes gland deflection, causes bite phenomenon；(3) gland withdrawing device of the present utility model avoids because the dismounting of violence formula causes the damage of equipment, is effectively guaranteed service life of equipment；(3) labor intensity that gland withdrawing device of the present utility model can effectively reduce a staff, shortens the main line repair time, it is ensured that repair quality.
