Description

Technical Field

[0001] The utility model relates to the technical field of stop valves, in particular to a stop valve body capable of distinguishing between high and low ends. Background Art

[0002] Patent No. CN215214935U discloses a stop valve body that can distinguish between high and low ends. The utility model has a reasonable structural design, which is convenient for operators to distinguish between high and low ends for installation, and the leakage pipe provided at the bottom is convenient for operators to check.

[0003] However, for the above-mentioned existing stop valve body that can distinguish between high and low ends, when the operator needs to install the stop valve body, he first installs the stop valve body by observing the indicator arrows on the front surface. The indicator arrows for the low-end cavity of the valve body are on the left side of the fixing plate, and the indicator arrows for the high-end cavity of the valve body are on the right side. At this time, the stop valve is installed. When the operator determines that the high and low end cavities are completed, the stop valve body can be installed through the mounting hole by using a fixing device. Since the device lacks a flow adjustment structure, it is inconvenient for the user to control the liquid outlet flow in daily use.

[0004] In order to solve the above problems, the utility model provides a stop valve body capable of distinguishing between high and low ends. Utility Model Content

The left side of the fixed plate is the indicator arrow of the valve body's low-end cavity, and the right side is the indicator arrow of the valve body's high-end cavity. At this time, the stop valve is installed. When the operator determines that the high and low end cavities are completed, the stop valve body can be installed through the mounting hole by using a fixing device.

[0019] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0020] Thus, a feature indicated in this specification will be used to illustrate one of the features of an embodiment of the utility model, rather than implying that each embodiment of the utility model must have the described feature. In addition, it should be noted that this specification describes many features. Although some features can be combined together to illustrate possible system designs, these features can also be used in other combinations that are not explicitly described. Thus, unless otherwise stated, the described combinations are not intended to be limiting.

[0021] The principle and structure of the present invention are described in detail below with reference to the accompanying drawings and embodiments:

[0022] refer to Figure 1-4 A stop valve body that can distinguish between high and low ends includes a valve body 1, a low-end pipe 7 is fixedly connected to the side of the valve body 1, a high-end pipe 10 is fixedly connected to the side of the valve body 1, a cover plate 2 is sealedly connected to the upper end surface of the valve body 1, a threaded hole 13 is opened on the upper end surface of the cover plate 2, a screw rod is threadedly connected to the threaded hole 13, a handle 6 is fixedly connected to the top of the threaded rod 5, a stop block 14 is fixedly connected to the bottom end of the threaded rod 5, a partition 11 is fixedly connected to the inside of the valve body 1, a flow hole 12 is opened on the upper end surface of the partition 11, and the side of the stop block 14 is clamped in the flow hole 12.

[0023] By providing the cut-off block 14 , the worker can drive the cut-off block 14 to move up and down through the threaded rod 5 , and the cut-off block 14 is separated from the flow hole 12 , so that the flow rate of the liquid can be controlled.

[0024] Furthermore, one end of the low-end pipeline 7 is connected to the inside of the valve body 1 , and one end of the high-end pipeline 10 is connected to the inside of the valve body 1 .

[0025] Furthermore, the surfaces of the low-end pipe 7 and the high-end pipe 10 are both slidably connected with threaded sleeves 8 , and one end of the low-end pipe 7 and the high-end pipe 10 are both fixedly connected with sealing rings 9 .

[0026] By providing the threaded sleeve 8 , a worker can install the device on a pipeline through the threaded sleeve 8 .

[0027] Furthermore, the cover plate 2 and the side surfaces of the valve body 1 are fixedly connected with a fixing block 3, and the fixing block 3 is internally threadedly connected with a mounting screw 4.

[0028] By providing the mounting screw 4 , the cover plate 2 can be sealed and mounted on the valve body 1 through the mounting screw 4 .

[0029] Furthermore, the diameter of the threaded rod 5 matches the diameter of the threaded hole 13 , and the shape of the cut-off block 14 matches the shape of the flow hole 12 .

[0030] Furthermore, the shape of the cut-off block 14 is set to be conical, and the diameter of the partition plate 11 matches the inner diameter of the valve body 1 .

[0031] The working principle of the utility model is as follows: first, the staff can tighten the low-end pipe 7 and the high-end pipe 10 on the pipe surface through the threaded sleeve 8. In daily use, the staff can drive the threaded rod 5 to rotate clockwise through the handle 6, and the threaded rod 5 drives the cut-off block 14 to move upward and separate from the flow hole 12. The flow rate can be controlled by controlling the rising distance of the cut-off block 14. At this time, the liquid can flow from the high-end pipe 10 into the valve body 1, and the liquid flows out between the cut-off block 14 and the flow hole 12 and flows into the low-end pipe 7. When it is necessary to close the flow in the pipe, the staff only needs to rotate the threaded rod 5 counterclockwise to drive the cut-off block 14 to move downward into the flow hole 12, and then the valve body can be closed.

[0032] Compared with the prior art, the worker only needs to drive the cut-off block 14 to separate from the flow hole 12 through the threaded rod 5, so as to control the size of the liquid outflow.

[0033] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the utility model, and these modifications or replacements should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
