Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention are described in further detail below.
Example 1
In order to achieve the above object, referring to fig. 1 and 2, an embodiment of the present invention provides a transceiver device with pressure, including: an end cover 1, an outer cylinder 2 and an inner protective pipe 3; one end of the outer cylinder 2 is provided with a flange 23 and a ball valve 22, the top 21 of the outer cylinder 2 is connected with the end cover 1 by adopting a thread connection, and the end cover sealing ring 13 is adopted for sealing; one end of the inner protective pipe 3 is provided with a sealing boss 31, the outer diameter of the sealing boss 31 is attached to the inner wall of the outer cylinder 2, the inner part of the inner protective pipe 3 is divided into an inner chamber 32 and an outer chamber 25, the inner chamber 32 is communicated with liquid in the pipeline, the outer chamber 25 is communicated with the outside through a ball valve 22, and preferably, the ball valve 22 is a stainless steel ball valve.
The sealing boss 31 can freely slide on the inner wall of the outer cylinder 2, so that the whole inner protective tube 3 is driven to freely slide in the outer cylinder 2; a boss sealing ring 33 is arranged on the sealing boss 31; the other end of the inner protective tube 3 is provided with a flexible tube 34, and the connection mode can be screwing, welding or bonding, and preferably adopts a welding mode; the function of the flexible tube 34 is to protect the detection device 41 and the cable 42 from damage during the detection process.
Preferably, the flexible tube 34 may be a commercially available stainless steel threaded hose; other flexible hoses of similar flexible construction may also be employed, for example: nylon corrugated pipe, PU pipe, PE pipe, silicone tube and the like; the inner protective pipe 3 is provided with a flange sealing ring 24 at the position penetrating through the flange plate 23, so that the fluid in the outer chamber 25 is ensured to be isolated from the fluid in the pipe.
Preferably, the end cap 1 is provided with a threading hole 11 for threading a cable of the cable detection device 41; preferably, a threading sealing ring 12 is further disposed in the threading hole 11 for sealing between the threading hole 11 and the cable 42 of the pipeline inspection device.
Preferably, the end cover 1 is further provided with an auxiliary circular hole 14 for smoothly lowering the boosting detection equipment 41 into the pipeline 6 to be detected.
Example 2
The operation of the transceiver in embodiment 1 is further described with reference to fig. 3, and is described in detail as follows:
as shown in fig. 3, the working principle of the transceiver is that the whole device is arranged on the gate valve 5 above the pipeline 6 to be tested when in use. Before use, the detection device 41 is placed in the inner protective tube 3, and the cable 42 of the detection device is connected to the outside through the threading hole 11; when the pipeline 6 to be detected normally runs, the internal water pressure is high, the inner chamber 32 is filled with high-pressure water by opening the gate valve 5, and the pressure acts on the boss end face 35 on the inner protective pipe 3, so that the inner protective pipe 3 drives the detection equipment 41 to move downwards. During this process the space of the outer chamber 25 is gradually compressed and the liquid therein is discharged to the outside through the ball valve 22.
In practice, the speed of the downward movement of the inner sheath 3 can be controlled by the size of the opening and closing of the ball valve 22, and when the ball valve 22 is fully closed, the pressure of the outer chamber 25 is balanced with the pressure of the inner chamber 32, and the inner chamber 32 no longer moves downward. The inner shroud 3 descends at a maximum rate when the ball valve 22 is fully opened, and does not stop moving until reaching the bottom of the outer tub 2. The ball valve 22 is prohibited from being in the fully open state in order to avoid damage caused by the collision.
When the detection task is completed to recover the detection device 41, the inner protection pipe 3 needs to be raised to the inside of the outer tube 2, otherwise the gate valve 5 cannot be closed. At this time, high-pressure fluid is injected into the outer chamber 25 through the ball valve 22, and the inner protection pipe 3 slowly rises under the pressure until the boss end face 35 abuts on the end cover 1, so that the gate valve 5 can be closed. When the detection device 41 is taken out, the ball valve 22 needs to be opened to perform pressure relief treatment, so that the end cover 1 cannot be unscrewed.
In the embodiment of the present invention, except for the specific description of the model of each device, the model of other devices is not limited, as long as the device can perform the above functions.
Those skilled in the art will appreciate that the drawings are only schematic illustrations of preferred embodiments, and the above-described embodiments of the present invention are merely provided for description and do not represent the merits of the embodiments.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
