Abstract

The invention discloses a one-way valve and relates to the technical field of pipeline transport. The one-way valve comprises a valve body. An inner cavity of the valve body is sequentially equipped with a valve plug, a spring and a spring base from the inside out. The valve plug is provided with a spherical sealing surface; a rubber seal block embedded in the valve body is arranged between the valve plug and the valve body; the rubber seal block is provided with a fluid passageway; and the end, close to the valve plug, of the rubber seal block is provided with a ring slot arranged outside a mouth of the fluid passageway. The rubber seal block is provided with the ring slot arranged outside the mouth of the fluid passageway; the ring slot enables the rubber seal block to form inner and outer two layers of tube walls which are easy to have elastic deformation; the ring slot leaves a space for elastic deformation of the inner-layer tube wall; and a fluid medium fills the ring slot and exerts a radial pressure on the inner-layer tube wall to enable the rubber seal block to be fitted with the spherical sealing surface of the valve plug better, thereby preventing leakage. According to the one-way valve, the inner cavity of the valve body no longer needs a seal cone hole, the valve body processing is easy, and cost is reduced.

Description

technical field [0001] The invention relates to the technical field of pipeline transportation, in particular to a one-way valve installed on the pipeline. Background technique [0002] The one-way valve is a one-way opening and closing valve that controls the flow of the fluid medium in the pipeline only in one direction and does not allow it to flow back in the opposite direction. There is a one-way valve that includes a valve body and a valve body The inner chamber is equipped with a valve plug, a spring and a spring seat sequentially from the inside to the outside, the valve plug is provided with a sealing cone, and the valve body is provided with a sealing cone hole matched with the sealing cone of the valve plug. Because the sealing taper hole is processed in the inner cavity of the valve, the processing is difficult and the manufacturing cost is high. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a one-...
