The utility model discloses the technical scheme who takes:
a guide and valve seat integrated lifting check valve comprises a valve body, a guide valve seat, a valve clack and a valve cover, wherein the guide valve seat is arranged on the side wall of an upper cavity flow opening and a lower cavity flow opening of the valve body, a gasket is arranged between the guide valve seat and the side wall of the flow opening, a plurality of through holes are formed in the peripheral wall of the lower part of the guide valve seat, the guide valve seat is tightly attached to the inner side wall and sleeved with the valve clack, the top of the valve body is connected with the valve cover through a bolt and a nut, the top of the guide valve seat is abutted to the bottom of the valve cover, the upper part of the guide valve seat is contacted with the upper part of the inner wall of the upper cavity of the valve body, a sealing gasket is arranged on the contact surface of the valve cover, the valve clack groove with a downward opening is formed in the middle of the bottom of the valve cover, the, the spring is sleeved on the upper portion of the valve clack, the upper portion of the spring is embedded into the spring groove, the bottom of the spring abuts against the transition table in the middle of the valve clack, and the middle of the top of the valve cover is in threaded connection with a lifting bolt.
The number of the through holes on the peripheral wall of the guide valve seat is more than 3.
The bottom of the guide valve seat is designed into a step shape, the upper surface of the side wall of the flow opening of the valve body is also designed into a step shape, and the step-shaped bottom of the guide valve seat is matched and connected with the step-shaped upper surface of the flow opening.
The utility model has the advantages that: the utility model discloses a direction disk seat plays the location guard action to the spring, avoids the spring to drop when the valve gap is opened, and traditional welding or threaded connection are avoided adopting as the disk seat of valve clack to the direction disk seat simultaneously for the direction disk seat is easily dismantled, and the online maintenance of being convenient for is changed.
