Description
Technical field
A kind of spring pre-tightening pipe collar of the present invention, for the field such as electric power, chemical industry pretension.
Background technique
At present, the pipe collar of two lobes or multiple even number lobe generally puts together on together with bolt by the pipe collar on pipeline, often need artificial pretension, otherwise ducted medium will leak, and causes manual inspection labor intensity large.The field such as electric power, chemical industry needs a kind of pipe collar without human at periodic intervals's pretension for this reason.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of spring pre-tightening pipe collar, not need human at periodic intervals's pretension bolt just can sealed pipe road junction,
Above-mentioned purpose of the present invention is realized by such technological scheme: a kind of spring pre-tightening pipe collar, comprises left lobe hoop, right lobe hoop, left lobe seat, right lobe seat; Interior rubber ring is provided with between left lobe hoop and right lobe hoop, left wedge type arc plate is provided with below inside described left lobe hoop, described right lobe hoop inner crest face is provided with right wedge type arc plate, and left lobe pretension bolt is successively through fixing behind left lobe seat, left preloading spring, left lobe hoop upper end, right lobe hoop upper end; Right lobe pretension bolt is successively through fixing behind right lobe seat, right preloading spring, right lobe hoop lower end, left lobe hoop lower end.
Described left lobe hoop upper end is provided with upper left and holds out against face, and left lobe hoop lower end is provided with lower-left and holds out against face; Described right lobe hoop upper end is provided with upper right and holds out against face, and right lobe hoop lower end is provided with bottom right and holds out against face.Left lobe pretension bolt holds out against face through left lobe seat, left preloading spring, lower-left successively, upper right is fixed by upper cap nut after holding out against face; Right lobe pretension bolt holds out against face through right lobe seat, right preloading spring, bottom right successively, lower-left is held out against face and fixed by lower nut.
Described upper left holds out against face and is provided with left upper port, and upper right holds out against face and is provided with upper right hole; Lower-left holds out against face and is provided with hole, lower-left, and bottom right holds out against face and is provided with hole, bottom right.
A kind of spring pre-tightening pipe collar of the present invention, tighten upper and lower nut simultaneously, left lobe seat is made to compress left preloading spring and right preloading spring together with right lobe seat, left and right preloading spring is made to produce enough pretension elastic force, this acts on interior rubber ring all the time to pretension elastic force, achieves the technique effect that just can reach interior rubber ring sealed pipe road junction without human at periodic intervals's pretension bolt.
This apparatus structure is simple, practical, easy to use, can be widely used in the field such as electric power, chemical industry.
