Abstract

The invention discloses a pressure check valve structure which comprises an outer shell. The lower end of the outer shell is provided with an oil nozzle part; a through hole runs through one end of the outer shell and the oil nozzle part; the inner wall of the through hole is provided with an arc groove; a moving valve is arranged in the through hole; the moving valve is of an internal hollow structure; the moving valve consists of a valve cover, an oil outlet part and a screw thread part; the screw thread part is provided with an arc screw thread coincided with the arc groove; one end of the screw thread part, which is towards the direction of the outer shell, is sequentially connected with the oil outlet part and the valve cover; and the oil outlet part is provided with a plurality of oil outlet holes. Compared with the prior art, the pressure check valve structure disclosed by the invention adopts a rotary oil suction structure, so that oil liquid in a check valve is sufficiently mixed and is difficult to solidify and deposit sundries; and the pressure check valve structure utilizes matched rotation of the screw thread and the screw thread groove to lift up the moving valve, so that large impact of oil liquid in a common check valve also can be relieved and part equipment is prevented from being damaged due to the large impact.

Description

technical field [0001] The invention relates to a pressure check valve structure. Background technique [0002] Ordinary one-way valves will accumulate oil after the machine stops running, and the oil may partially solidify. Over time, sediment may adhere to the inner cavity, which is difficult to remove, affecting the smooth flow of the one-way valve, and even damaging the equipment. other parts inside. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a pressure check valve structure for the above-mentioned deficiencies in the prior art. [0004] In order to solve the above-mentioned technical problems, the technical solution adopted in the present invention is: a pressure check valve structure, including an outer shell, an oil nozzle part is arranged at the lower end of the outer shell, and a through hole is arranged through one end of the outer shell and the oil nozzle part, and the inner wall of the through h...
