Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0023] Such as Figure 1~5 As shown, a PE full-way globe valve includes a valve body 1, a valve core 2, a rotating shaft 3 and a valve cover 5, the rotating shaft 3 is rotatably connected to the valve cover 5, and the valve core 2 is connected to the rotating shaft 3, the valve cover 5 is connected to the valve body 1, and the pipeline in the valve body 1 is a straight full-through pipeline. The pipeline in the valve body 1 is provided with a conical counterbore, and the valve cover 5 is provided with a prismatic counterbore 501 and a shaft through hole 502 . The spool 2 includes a conical structure 202 and a prismatic structure 201. The conical structure 202 has the same taper as the conical counterbore. It is threadedly connected with the rotating shaft 3 , and one end of...

Abstract

The invention relates to a PE all-pass stop valve. The PE all-pass stop valve comprises a valve body (1), a valve core (2), a rotating shaft (3), a hand wheel (4) and a valve cover (5), wherein the rotating shaft (3) is rotatably connected with the valve cover (5); the hand wheel (4) is sleeved on the rotating shaft (3); the valve core (2) is connected with the rotating shaft (3); the valve cover(5) is connected with the valve body (1); an inner pipeline of the valve body (1) is a linear all-pass pipeline; the valve core (2) comprises a conical structure (202) and a prismatic structure (201);the conical structure (202) is as same as conical degree of a conical counter bore in the valve body (1); the prismatic structure (201) is matched with a prismatic counter bore in the valve body (1);inner threads are arranged on the prismatic structure (201); and the prismatic structure (201) is connected with the rotating shaft (3). According to the PE all-pass stop valve, the inner pipeline ofthe valve body (1) is the linear all-pass pipeline; the flowing resistance is small; and the valve core rises and falls through threads, so that the valve core has a throttling function.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a PE full-pass stop valve. Background technique [0002] The globe valve is one of the pipeline connection valves, also known as the gate valve, which belongs to the forced closing valve. Therefore, when the valve is closed, pressure must be applied to the valve core to force the sealing surface not to leak. At present, the conventional globe valves are angle globe valves and straight-through globe valves. The pipes in the valve body of the angle globe valve have upward and downward curved pipe structures respectively, and the joints of the two curved pipe structures form upward and downward sealing surfaces, and the sealing surface cooperates with the valve core to achieve the sealing effect. The structural volume is large, and the flow resistance is also large, which limits the flow velocity of the fluid in the pipeline. The pipeline in the valve body of the direct-flow globe...
