Description
Technical field
The invention belongs to the pressure-equalizing corrugated compensation device that pipeline is used, relate to the knee pipe pressure balance type compensator with force equalization mechanism.
Background technique
Conventional elbow pressure balanced compensator, technological scheme as disclosed in ZL2009201063820, by two work bellowss and a balance bellows, formed, wherein two work bellowss are when bearing axial displacement, its displacement amount often distributes inequality, therefore easily affects the working life of whole compensator.
Summary of the invention
The technical problem solving:
Knee pipe pressure balance type compensator with force equalization mechanism is provided, it is the improvement to ZL2009201063820, can overcome the deficiencies in the prior art, on the outer wall of the connection straight tube corresponding with two work bellowss, forward and backward symmetrically arranged connecting rod force equalization mechanism is housed, can make two work bellowss when bearing axial displacement, its displacement amount distributed uniform, is conducive to extend working life of whole compensator.
The technological scheme adopting:
Knee pipe pressure balance type compensator with force equalization mechanism, there are two work bellowss, a balance bellows, corresponding inlet connecting branch, nipple, long connecting tube, blind pipe, right-angle elbow pipe and drag link mechanism, it is characterized in that: on the outer wall of the connecting tube corresponding with two work bellowss, before being equipped with, rear symmetrically arranged two cover connecting rod force equalization mechanism, the plane of two link body at two cover connecting rod force equalization mechanism places is parallel to each other, simultaneously, the plane parallel of described link body is in the intersect vertically plane at place of the axis o-o ' of corresponding connecting tube and blind pipe and the axis y-y ' of right-angle elbow pipe, the structure of connecting rod force equalization mechanism is, on the outer wall of inlet connecting branch and long connecting tube, be welded with respectively and take two work bellowss as left and right symmetrical left and right hinged seat, in connecting rod force equalization mechanism, the left and right two ends of can automatic left and right equilibrium under the effect of axial displacement flexible link body, hinged by corresponding left and right fishplate bar on left and right bearing pin and left and right hinged seat respectively.
Beneficial effect:
Knee pipe pressure balance type compensator with force equalization mechanism, owing on the position corresponding with two work bellowss, forward and backward symmetrically arranged connecting rod force equalization mechanism being housed, therefore, the axial displacement that pipeline produces is under the effect of connecting rod force equalization mechanism, and equalization type is distributed to two work bellowss and given balance at any time, is therefore conducive to extend the working life of work bellows and whole compensator, simultaneously, simple in structure, be easy to making, installation and maintenance, cost is low.
