The invention adopts the following specific technical scheme: the utility model provides a filter equipment for heat supply pipeline, including the metal casing who adopts integrated into one piece technology to make, the casing divide into casing and lower casing, there is the contained angle below that lower casing is located the casing between the two, the inside of casing is provided with cylindrical filter screen down, cylindrical filter screen upwards extends partly to the supreme casing in, the inside at last casing is fixed on the upper portion of cylindrical filter screen adoption mounting, the one end that the casing was kept away from to the lower casing is passed through the flange and is linked to each other with the entrance point of a valve, flange on the casing down is set for first flange, the flange of valve entrance point is set for the second flange, first flange passes through the bolt fastening with the second flange.
In the technical scheme, the shell of the filtering device is cast and formed by using the mold, and comprises an upper shell and a lower shell, wherein the upper shell and the lower shell are cylindrical, the upper shell is used for being connected to a pipeline in normal operation, the upper shell and the lower shell can be directly connected with the pipeline in a welding or thread mode, shells with different calibers are cast according to the caliber of the pipeline, a cylindrical filter screen is arranged in the lower shell and upwards extends into the upper shell, the extending part is filled with the whole inner diameter of the upper shell, in the operation of the pipeline, fluid in the pipeline flows in parallel, impurities in the pipeline are intercepted by the filter screen or are precipitated into the lower shell under the action of self gravity, and meanwhile, due to the action of gravity, the fluid filled in the lower shell is also in the lower shell, and the precipitated impurities are positioned in the lower shell, so that the fluid flowing through the upper.
The invention further improves the structure that a fixing part connected with the cylindrical filter screen is arranged on the inner wall of the upper shell in an inward extending mode, the fixing part is provided with threads, the position where the cylindrical filter screen is connected with the upper shell is also provided with threads, and the cylindrical filter screen and the upper shell are fixed together in a threaded connection mode. This improvement needs improve the mould when the mould opening, sets for the screw thread, adopts threaded connection, is convenient for change the filter screen.
The invention is further improved, and the valve adopts an all-welded ball valve.
In a further improvement of the present invention, two gaskets made of rubber are disposed between the first flange and the second flange, and are configured as the first gasket and the second gasket, so as to facilitate sealing.
The invention further improves the structure that two ends of the upper shell are provided with the blank caps which are set as the upper blank caps, the outlet end of the valve is provided with the blank cap which is set as the lower blank cap, and the arrangement of the blank caps ensures that the whole filtering device is in a sealed state and is convenient to store and transport.
The invention is further improved, the included angle between the upper shell and the lower shell is 45 degrees, the 45 degrees are set to enable the cylindrical filter screen to be equal to the connecting part inside the upper shell, and the impact force of the fluid flowing through the upper shell to the filter screen drives the pressure to the upper shell to be equal up and down.
The invention has the beneficial effects that: the invention has simple structure and good filtering effect, can discharge impurities in the lower shell by opening the valve, and is simple and convenient to operate.
