Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic views illustrating only the basic structure of the present invention in a schematic manner, and thus show only the constitution related to the present invention.
As shown in fig. 1-2, the present embodiment provides a stop valve guide structure, which includes a valve body 1 and a valve cover 2, a valve seat 3 for partitioning a liquid inlet/outlet chamber is disposed in the valve body 1, an upward protruding neck 4 is disposed in the middle of the valve body 1, a valve rod 5 is disposed in the valve cover 2 in a penetrating manner, the valve rod 5 is connected to a valve flap 6 located on the valve seat 3, and the valve flap 6 is lifted and controlled to be in sealing fit with the valve seat 3 through the valve rod 5; a plurality of guide ribs 7 which are in the same direction as the valve rod 5 are uniformly distributed on the inner wall of the neck opening 4 in the circumferential direction, preferably, three guide ribs 7 are arranged and are integrally formed with the neck opening 4, the three guide ribs 7 can form stable supporting guide, and the forming and connecting effect is good by adopting an integrally formed production process; the surface of the guide rib 7 is smooth to reduce friction, and any guide rib 7 is connected with the peripheral surface of the valve clack 6 in a sliding mode.
During assembly, the valve rod 5 is connected with the valve clack 6 and then is arranged in the valve body 1 from the neck opening 4 until the valve clack 6 reaches the position of the valve seat 3, the valve clack 6 is guided in a sliding mode under the combined action of the three guide ribs 7 in the process, the valve rod 5 is lifted up and down for several times, and the valve clack 6 is confirmed to be opened without obstacles. The stop valve has the advantages of simple guide structure, low cost and good effect, and can be realized only by simply modifying the valve body 1.
In order to facilitate the connection of the valve rod 5 and the valve clack 6, the bottom of the valve rod 5 is sleeved with a valve clack cover 8, and the valve clack 6 is in threaded connection with the bottom of the valve clack cover 8.
