Abstract
The utility model discloses a two adjustable shrinkage cavity valves of pillar chain drive of buggy pipeline, include: casing, upper sprocket wheel, lower whorl sprocket, core, turnscrew, elevating screw, the side of casing set up to the infundibulate, the turnscrew install on the casing right side, its upper portion and cochain endless chain rotate, lower part and sprocket chain drive down, the core be the semi -circular arc board of from top to bottom installation, the core be connected with elevating screw, elevating screw be the reverse short silk thick stick of two screw threads, the one end of turnscrew be provided with the rocking arm. The core passes through the chain and drives the lead screw, realizes opening and shutting in step. Through implementing above technical scheme, technological effect below having: the utility model provides a shrinkage cavity equipment and simple structure, rapid operation, hourglass outside not having, daily operation low cost, the maintenance convenience that the buggy pipeline is adjustable.
Description
Technical field
The utility model relates to Controlling Auxiliaries in Power Plants equipment, particularly the two pillar Chain conveyer adjustable contraction valve of a kind of pulverized coal channel.
Background technique
Along with the development of power plant, the effect of electric power subsidiary engine in daily production becomes more and more important, and the simplification of the operational reliability of subsidiary engine equipment, the convenience of operation, maintenance more and more comes into one's own; The shortcomings such as the wherein adjustment of coal pulverizer export coal powder pipeline pressure and powder sending quantity is all realize by adjustable contraction, and existing equipment exists operation effort, easily dust stratification, it is serious to leak outside, maintenance and repair is inconvenient.
Summary of the invention
The purpose of this utility model is, overcomes the deficiencies in the prior art, and provides a kind of structure simple, and rapid operation, without leaking outside, day-to-day operation is with low cost, the two pillar Chain conveyer adjustable contraction valve of a kind of pulverized coal channel easy to maintenance.
To achieve these goals, the utility model provides following technological scheme:
The two pillar Chain conveyer adjustable contraction valve of a kind of pulverized coal channel, comprising: housing, upper sprocket wheel, lower wheel sprocket, central layer, turn-screw, elevating screw; The side of described housing is set to funnel shape, and described turn-screw is arranged on the right side of housing, and its top and cochain endless chain rotate, bottom and lower sprocket Chain conveyer; Described central layer is the semi-circular arc plate installed up and down; Described central layer is connected with elevating screw; Described elevating screw is the reverse short leading screw of two screw threads; One end of described turn-screw is provided with rocking arm.Central layer, by chain-driving leading screw, realizes synchronous on-off.
By implementing above technological scheme, have following technique effect: the pulverized coal channel adjustable contraction equipment that the utility model provides and structure are simple, rapid operation, without leaking outside, day-to-day operation is with low cost, easy to maintenance.
