Description

Pipeline welding type axial flow check valve

Technical Field

The utility model relates to the technical field of valves, especially, relate to a pipeline welding formula axial compressor check valve.

Background

Along with the development of urbanization, the population of cities and towns is more and more, the development of city and town infrastructure construction is accelerated, and the requirement on an intelligent integrated pump station is higher and higher. The requirement on the installation space of the integrated pump station is more and more compact, so that the structure of the check valve used in the integrated pump station needs to be more compact, and the requirement on the check function of the check valve is more strict; the angle valve with the non-return function in the market at present has the defects of complex structure, high cost, large flow resistance and large leakage amount of a valve seat.

Disclosure of Invention

The utility model aims at overcoming the not enough of prior art, provide a pipeline welding formula axial compressor check valve, the utility model discloses a realize through following technical scheme: a pipeline welding type axial flow check valve comprises a pipeline, a fixed seat and a valve seat, wherein the fixed seat is welded in the pipeline, the valve seat is welded in the pipeline, a rubber seat is mounted on the valve seat, a rubber pressing plate is mounted on the rubber seat, a valve core is mounted on the rubber pressing plate, the valve core and the rubber pressing plate are fastened through screws, a spring is mounted on the valve core, a planar rolling bearing is mounted on the spring, a pressure adjusting seat is mounted on the planar rolling bearing, a check nut is mounted on the pressure adjusting seat, the check nut and the fixed seat are connected with the pressure adjusting seat through threads, when the pipeline welding type axial flow check valve is used on site, the stroke of the pressure adjusting seat can be adjusted and set according to the medium pressure in a working condition, when a medium flows from the end of the valve seat to the end of the fixed seat; when the medium flows to the valve seat from the end of the fixed seat, the valve core is under the action of spring force and medium thrust, so that the rubber seat only seals the valve seat, and the medium in the pipeline has a non-return function; compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses simple structure, installation space is compact, and whole structural installation is in the pipeline, so the appearance is simple pleasing to the eye, and the cost of manufacture is low, and non return sealing performance is good, economical and practical.
