Abstract
The utility model discloses a front-to-back washing bridge type controlling apparatus. The once water system of the stator, and rotor water cooling winding of the present turbo generator adopts the decentralized control mode. The immediate performance can not be realized when adjusted. The work efficiency is low. The front-to-back washing bridge type controlling apparatus comprises a water inlet pipeline 1. The water inlet pipeline is connected with four valve pipelines 5 in the mode of bridge connection. The water inlet pipeline 1 is connected with a collector ring pipeline 7. A valve pipeline 6 like a butterfly valve 51 is isolated between the water inlet pipeline 1 and the collector ring pipeline 7. A refluxing pipeline 9 of the collector ring pipeline 7 is provided with a valve 8 which is connected with a pipeline 10 provided between a valve 53 and a valve 54 which are one side of the diagonal of the valve pipeline 5 in the mode of bridge connection. A pipeline 11 which is arranged on one side of the diagonal of the water inlet pipe path 1 and is provided between a valve 52 and the valve 53 is connected with an outlet pipe 12. The pipeline 11 is arranged on the valve pipeline 5 in the mode of bridge connection. The utility model can be used for the front-to-back washing of the once water system of the stator, and rotor water cooling winding of the present turbo generator.
Description
Technical field: the utility model relates to the positive backwash bridge-type control device that an a kind of water system of stator, rotor water-cooled winding of turbo generator uses.
Background technology: a water system of the stator of existing turbo generator, rotor water-cooled winding adopts nail, rotor, forward, back flush decentralized control, distance is big between the valve that is associated, the display unit, can not realize instantaneity during adjustment, inefficiency, therefore operating accident often takes place, and has expended a large amount of pipelines and corresponding building materials.
Summary of the invention: the purpose of this utility model provides a kind of central controlled, safe and reliable novel positive backwash bridge-type control device.
Above-mentioned purpose realizes by following technical scheme:
Positive backwash bridge-type control device, its composition comprises: inlet pipeline, the valve pipeline that described inlet pipeline links to each other with four bridge-types links to each other, link to each other with the collector ring pipeline with the be separated by pipeline of a valve of described inlet pipeline, diagonal angle one side of the valve pipeline that valve is housed on the return line of described collector ring pipeline and links to each other with described bridge-type links to each other, and links to each other with outlet pipe with the pipeline of described inlet pipeline diagonal angle one side on the valve pipeline that described bridge-type links to each other.
Above-mentioned positive backwash bridge-type control device, described collector ring pipeline links to each other with the pipeline that leads to bus-bar room, and break valve A and flowmeter are equipped with in series connection on this pipeline, are parallel with another break valve B on the line segments of described break valve A and flowmeter.
Above-mentioned positive backwash bridge-type control device is equipped with water filter and flow of inlet water meter on the described inlet pipeline, the valve on the valve pipeline that described four bridge-types link to each other is a butterfly valve, and above parts are contained in the housing.
This technical scheme has following beneficial effect:
1. adopt valve is connected according to the bridge-type connected mode, constitute functional fluid pressure line structure, easy for installation, compare with old backwashing manner, overcome the situation of acting hurriedly in a messy situation, waste time and energy of original distributing operation.This product passes through the control to different valve opening and closing states, the positive and negative flushing work of finishing the disposable water system of turbo generator stator and rotor water-cooled winding that can be safe and reliable.
2. be convenient to centralized control, can positive direction wash and water flowing, and can carry out Automatic Cycle on inlet pipeline, and can adjust pressure easily by the valve opening size by water collection assembling device is installed with opposite direction by valve control.
Description of drawings: accompanying drawing 1 is the structural representation of this product.
Accompanying drawing 2 is pipeline connection diagrams of this product.
