Embodiment 1

[0022] like figure 1 As shown, a single-flow column valve, the technical solution of the present invention is: a single-flow column valve, comprising: a valve body 1, a valve body chamber 6 is arranged in the valve body 1, and the valve body 1 is circumferentially arranged There are several valve body connecting pipes 3, the valve body connecting pipe 3 communicates with the valve body chamber 6 through the valve body connecting pipe flow channel 15; the valve core 2, the valve core 2 is provided with a valve core chamber 22, the valve core 2 The valve core 2 is provided with a sliding sleeve 14, the valve core 2 and the sliding sleeve 14 are rotatably installed in the valve body cavity 6, and the valve core 2 is provided with a valve core hole 5 in the circumferential direction. The sleeve 14 is provided with a sliding sleeve hole 4 in the circumferential direction; the end cover 20 is fixedly connected with the valve body 1, and the end cover 20 is provided with an end cover...

Embodiment 2

[0026] On the basis of Embodiment 1, in this embodiment, preferably, the center line of the valve core hole 5 and the valve body connection pipe flow channel 15 are located on the same circumferential plane, and the number of the valve body connection pipes 3 is ≥ 2. The sliding sleeve hole 4 is parallel to the center line of the valve core hole 5 , and the projections on the circumferential plane coincide.

[0027] like image 3 As shown, in actual use, the valve core hole 5 and the center line of the valve body connecting pipe flow channel 15 are located on the same circumferential plane, which ensures that the valve core hole 5 is connected to the valve body during the rotation of the valve core 2. The pipe flow channel 15 can be accurately aligned, thereby ensuring the normal opening of the flow channel; the sliding sleeve hole 4 is parallel to the center line of the valve core hole 5, and the projections on the circumferential plane coincide, ensuring that the sliding sl...

Embodiment 3

[0029] On the basis of Embodiment 2, in this embodiment, preferably, the valve core 2 is divided into two sections connected in sequence, and the outer diameter of the first section close to the end cover 20 > the outer diameter of the first section away from the end cover 20 The outer diameter of the second section, the valve core 2 is axially positioned with the positioning step 17 in the valve body 1 through its first section. The outer diameter of the sliding sleeve 14 is the same as the inner diameter of the valve body 1 , and the inner diameter of the sliding sleeve 14 is the same as the outer diameter of the second section of the valve core 2 . The second section of the spool 2 is provided with a groove 13 near the center of one end of the valve stem 9. The notch of the groove 13 is a rectangle, and the symmetry axis of the rectangle is parallel to the long side and the centerline of the spool hole 5. parallel, and the projections on the circumferential plane coincide. ...

Abstract

The invention belongs to the field of pipeline valve tools, and particularly relates to a check column valve. The check column valve comprises a valve body, a valve element, an end cover and a valve rod, wherein a valve body cavity is formed in the valve body, and a plurality of valve body connecting pipes are arranged in the circumferential direction of the valve body; a valve element cavity is formed in the valve element, a sliding sleeve is arranged outside the valve element, the valve element and the sliding sleeve are rotatably installed in the valve body cavity, a valve element hole is formed in the circumferential direction of the valve element, and a sliding sleeve hole is formed in the circumferential direction of the sliding sleeve; the end cover is fixedly connected with the valve body; and one end of the valve rod is fixedly connected with the sliding sleeve, and the other end of the valve rod is connected with a driving device. Through cooperation of the valve element andthe sliding sleeve, alignment and staggering of the sliding sleeve hole and the valve element hole and alignment of the valve element hole and a valve body connecting pipe runner are achieved under the action of the driving device, and therefore the processes of opening and closing of the valve and branch switching are achieved, operation is easy and convenient, practicability is high, and the check column valve can be widely applied to a pipeline structure needing one-way control over multiple branch pipelines.

Description

technical field [0001] The invention belongs to the field of pipeline valves, in particular to a single-flow column valve. Background technique [0002] The valve is a control component in the fluid delivery system, which has functions such as cut-off, adjustment, flow diversion, reverse flow prevention, pressure stabilization, flow diversion or overflow pressure relief. Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. [0003] In the chemical process, it is sometimes necessary to change the flow direction of the medium, that is, to switch the fluid medium from a certain pipeline to other branch pipelines. However, most of the existing valves have a one-valve-one-channel structure, and their application is relatively simple. In order to realize the above technological process, the conventional design needs to open holes in the main pipeline and install multiple...
