A large flow plug-in flexible intercepting device

Abstract

This invention discloses a high-flow-rate insert-type flexible interception device, belonging to the field of valve technology. It includes a cylinder, an air nozzle, an inner liner, and a fixing component. The air nozzle is located on the outer side of the cylinder, and the inner liner is fixedly connected inside the cylinder. A fixing component is fixedly connected to a non-section of the cylinder near the air nozzle. This invention can be easily installed at the discharge outlet of municipal or industrial pipelines. By controlling the flow of compressed air, the opening and closing of the flexible interception device is automatically controlled, achieving flow control of the discharged wastewater. Compared to traditional insert-type flexible interception devices, this invention significantly increases the flow rate of the flexible interception device for the same outer diameter. By moving the air nozzle to the side, the air gap caused by the original installation position for the air nozzle is no longer needed, and the inner liner can be closer to the inner wall of the outer cylinder, thus increasing the flow rate.

The air nozzle is provided on the outer side of the cylinder, the inner liner is fixedly connected inside the cylinder, and the fixing member is fixedly connected to the non-section of the outer side of the cylinder near the air nozzle.

[0005] Preferably, the inner liner includes an outer support ring, an upper inner support ring, an inner bushing, and a lower inner support ring. The upper and lower ends of the cylinder are fixedly connected to the outer support ring. The upper inner support ring is fixedly connected inside the upper outer support ring. The upper end of the inner bushing is clamped between the upper inner support ring and the outer support ring. The lower end of the inner bushing is clamped to the lower outer support ring through the lower inner support ring. The outer support ring is integrally formed with the cylinder.

[0006] Preferably, the fastener includes a flange and a sealing sleeve. An annular flange is fixedly connected to the outer end of the cylinder, and a sealing sleeve is fixedly connected to the rear of the flange.

[0007] Preferably, the sealing sleeve is a conical sealing sleeve, and its inner side is tightly fitted to the outer wall of the cylinder.

[0008] Preferably, when the flange is inserted into the pipe and tightened by the pressure plate, it is mated and fixed with the pre-embedded flange on the square well wall or with the pipe.

[0009] Beneficial effects:

[0010] This invention provides a high-flow-rate insert-type flexible interception device with the following advantages: Through its structural design, this device can be easily installed at the discharge outlet of municipal or industrial pipelines. The opening and closing of the flexible interception device is automatically controlled by controlling the flow of compressed air, thus achieving flow control of the discharged wastewater. Compared to traditional insert-type flexible interception devices, this device significantly increases the flow rate for the same outer diameter. By moving the air nozzle to the side, the air gap created by the original installation position for the air nozzle is no longer needed, and the inner liner can be closer to the inner wall of the outer cylinder, thereby increasing the throughput.

[0014] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0015] In the description of this invention, it should be noted that the terms "upper / lower end," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0016] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "set / sleeved," "sleeved," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0017] Please see Figure 1-2 The present invention provides a high-flow-rate insertion flexible interception device, including a cylinder 1, an air nozzle 2, an inner liner 3, and a fixing member 4. The air nozzle 2 is provided on the outer side of the cylinder 1, the inner liner 3 is fixedly connected inside the cylinder 1, and the fixing member 4 is fixedly connected to the non-section of the outer side of the cylinder 1 near the air nozzle 2.

[0018] Furthermore, the inner liner 3 includes an outer support ring 31, an upper inner support ring 32, an inner liner 33, and a lower inner support ring 34. The outer support ring 31 is fixedly connected to both the upper and lower ends of the cylinder 1. The upper inner support ring 32 is fixedly connected inside the upper outer support ring 31. The upper end of the inner liner 33 is clamped between the upper inner support ring 32 and the outer support ring 31. The lower end of the inner liner 33 is clamped to the lower outer support ring 31 through the lower inner support ring 34. The outer support ring 31 is integrally formed with the cylinder 1.

[0019] Furthermore, the fastener 4 includes a flange 41 and a sealing sleeve 42. The outer end of the cylinder 1 is fixedly connected to the annular flange 41, and the sealing sleeve 42 is fixedly connected to the rear of the flange 41.

[0020] Furthermore, the sealing sleeve 42 is a conical sealing sleeve, with its inner side tightly fitting against the outer wall of the cylinder 1. In use, its outer side tightly fitting against the inner wall of the pipe, achieving a seal between the cylinder 1 and the pipe.

[0021] Furthermore, when flange 41 is inserted into the pipe and tightened by the pressure plate, it is mated and fixed with the pre-embedded flange on the square well wall or with the pipe.

[0022] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires, and should select appropriate controllers according to actual conditions to meet control requirements.

The detailed connection methods are well-known technologies in the field. The following mainly introduces the working principle and process, and will not describe the electrical control further.

[0023] In this implementation plan:

[0024] Insert the side of the cylinder 1 away from the air nozzle 2 into the square well wall. The flange 41 is connected and fixed to the pre-embedded flange of the pipeline. The rear sealing sleeve 42 plays a role in sealing and preventing leakage. By inflating and deflating the air nozzle 2, the two sides of the inner liner 33 are deformed under the fixing action of the outer support ring 31, the upper inner support ring 32 and the lower inner support ring 34, thereby affecting the on / off state.

[0025] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
