Abstract
The invention discloses an elastic supporting device for a heat supply steam turbine communicating pipe butterfly valve, and relates to an elastic supporting device. The elastic supporting device solves the problem that a supporting contact face is easy to release or a communicating pipe is easy to break because the conventional supporting device for the heat supply steam turbine communicating pipe butterfly valve is used for rigid supporting. The lower end of a guiding pipe is fixedly arranged on the upper end face of a bottom support, a plurality of disc springs are stacked together from top to bottom and arranged on the lower part in the guiding pipe, the guiding rod consists of a big cylindrical section and a small cylindrical section, the upper end of the small cylindrical section is fixedly arranged in the center of the lower end face of the big cylindrical section, the lower end of the small cylindrical section passes through the plurality of disc springs and a central hole sequentially, the lower part of the big cylindrical section is inserted into the guiding pipe, the bottom end face of the big cylindrical section is in contact with the disc spring on the top, and the top support is arranged on the upper end face of the guiding rod through an adjustable screw. The elastic supporting device is used for supporting the heat supply steam turbine communicating pipe butterfly valve.
Description
Technical field
The present invention relates to a kind of support device of heat supply steam turbine cross over pipe butterfly valve, be specifically related to a kind of resilient supporting unit of heat supply steam turbine cross over pipe butterfly valve.
Background technique
The support device of existing heat supply steam turbine cross over pipe butterfly valve is a rigid support; During steam turbine operation, butterfly valve receives in the pipeline vapor pressure effect and possibly upwards be out of shape on the cross over pipe, when butterfly valve upwards is out of shape; Rigid support does not have supporting effect, supports surface of contact and possibly thread off; Vapor pressure often changes in the cross over pipe pipeline, when butterfly valve in pipeline under the vapor pressure effect when upwards becoming downward distortion, if the bottom does not have support, cross over pipe ruptures easily, causes a serious accident.
Summary of the invention
The present invention causes supporting the problem that surface of contact is prone to dropout or cross over pipe easy-rupturing for the support device that solves existing heat supply steam turbine cross over pipe butterfly valve is a rigid support, and then a kind of resilient supporting unit of heat supply steam turbine cross over pipe butterfly valve is provided.
The present invention solves the problems of the technologies described above the technological scheme of taking to be: the resilient supporting unit of heat supply steam turbine cross over pipe butterfly valve of the present invention comprises top support, can regulate screw rod and bottom support bracket; Be processed with center hole on the said bottom support bracket; Said resilient supporting unit also comprises guide rod, guide pipe and a plurality of dish spring; The lower end of said guide pipe is packed on the upper-end surface of bottom support bracket; A plurality of dish springs from top to bottom are stacked together and are arranged on the bottom in the guide pipe; Said guide rod is made up of great circle shell of column and roundlet shell of column, and the upper end of said roundlet shell of column is packed in the center of the lower end surface of great circle shell of column, and the lower end of said roundlet shell of column is passed a plurality of dish springs and passed by center hole; The bottom of said great circle shell of column is inserted in the guide pipe and the bottom end of great circle shell of column contacts with the dish spring that is positioned at the top, and said top support is installed on the upper-end surface of guide rod through the can regulate screw rod.
The invention has the beneficial effects as follows: resilient supporting unit of the present invention adopts guide rod, guide pipe and a plurality of dish spring to support heat supply steam turbine cross over pipe butterfly valve; With the support device of existing heat supply steam turbine cross over pipe butterfly valve is that rigid support is compared; Resilient supporting unit of the present invention has guaranteed that when butterfly valve upwards is out of shape the support surface of contact fits tightly; Played the effect of supporting, cross over pipe is easy-rupturing not, has improved Safety performance; Resilient supporting unit of the present invention is simple in structure, be convenient to Maintenance and Repair.
