The invention relates to the technical field of throttling valve devices, in particular to a filtering-type dual-sealing fixing throttling valve. The valve comprises a valve body, a union connector and a flange short segment; a first channel which runs through the upper and lower ends of the valve body is formed in the valve body, a second channel which runs through the left end of the valve bodyand the first channel is formed in the left portion of the valve body, and a mounting pipe is integrally fixed to the upper portion of the valve body; an inner cavity of the mounting pipe is communicated with the first channel, the union connector is fixedly installed in the upper portion of the mounting pipe, and a third channel is formed in the union connector, wherein the upper portion of the third channel is large, the middle of the third channel is small, and the lower portion of the third channel is large; the third channel, the inner cavity of the mounting pipe and the first channel arecommunicated in sequence, and a first plug is fixedly installed in a large hole of the upper portion of the third channel. The filtering-type dual-sealing fixing throttling valve is reasonable and compact in structure and convenient to use, an inner structure is provided with a filtering device, is of a dual-sealing structure and has a step-shaped mounting type, and the problem can be effectivelyavoided that an oil nozzle during normal production of ground open flowing is easily blocked, easily loosened and easily stabbed.
