Description

Technical Field

[0001] The utility model relates to the technical field of continuous casting starting pouring devices, in particular to an anti-loss device for the pipe cap of the discharge port of a petrochemical device. Background Technique

[0002] There are a large number of discharge ports at the device site in the petrochemical industry. The pipe diameters are generally between DN15 and DN25, and are used for purging and replacement, temporary sampling, steam drainage, temporary drainage ports for inspection, repair, etc. In order to prevent the leakage of toxic and harmful media in the pipeline into the atmosphere and soil environment due to valve internal leakage and other reasons when these discharge ports are not in use and pollute the environment, it is generally required to add pipe caps or plugs. Among them, the pipe cap is applicable to pipelines with external threads at the discharge port, and the plug is used for pipelines with internal threads at the discharge port. Among them, external threads are more common, and generally the pipe cap form is adopted.

[0003] As an independent pipe fitting, the pipe cap itself has no anti-loss measures. The pipe cap is small in size and has no fixed points. The removed pipe cap can only be placed nearby on the ground, valve, pipeline or other equipment and facilities. During on-site start-up, shutdown and inspection and repair, the personnel are complex and it is extremely easy to lose. The pipe caps of some discharge ports that need to be opened frequently are also lost due to reasons such as frequent disassembly and random placement. At present, only management measures and training and education measures can be relied on to minimize the loss as much as possible, but the effect is generally average and the effort is wasted. Content of the Utility Model

[0004] In order to solve the above problems, the utility model provides an anti-loss device for the pipe cap of the discharge port of a petrochemical device, and the technical scheme adopted is as follows:

[0005] An anti-loss device for the pipe cap of the discharge port of a petrochemical device, including a discharge pipe and a switching valve arranged on the discharge pipe. One end of the discharge pipe is threadedly connected with a pipe cap. It is characterized in that it further includes:

[0006] A first connecting rope, with a first wire locking device and a second wire locking device connected to both ends in the length direction. One end of the first connecting rope is fixedly connected with the pipe cap through the first wire locking device;

[0007] A second connecting rope, with a third wire locking device and a fourth wire locking device connected to both ends in the length direction. One end of the second connecting rope is fixedly connected with the discharge pipe through the third wire locking device;

[0008] A universal connecting ring, and the two rotating ends of the universal connecting ring are respectively connected with one ends of the first connecting rope and the second connecting rope through the second wire locking device and the fourth wire locking device.

[0009] Further, both rotating ends of the universal connecting ring are D-shaped rings.

[0010] Further, the pipe cap is an internal thread pipe cap.

[0011] Further, both the first connecting rope and the second connecting rope are steel wire ropes.

[0012] Further, the second connecting rope is connected to the discharge pipe at one end of the water inlet of the switching valve through a third wire locking device.

[0013] The beneficial effects of the present utility model are as follows:

[0014] 1. By fixing the pipe cap on the discharge pipe through the connecting rope, the problem of loss of the pipe cap caused by random disassembly can be avoided;

[0015] 2. The two groups of connecting ropes are respectively connected to the pipe cap and the discharge pipe, and the adjacent two groups of connecting ropes are rotationally connected by a universal connecting ring. When disassembling or installing the pipe cap, the rotation of the pipe cap will not cause the connecting rope to be twisted and deformed, improving the service life of the components and the reliability during the installation of the pipe cap.

[0021] As Figure 1 - Figure 2A device for preventing the loss of the pipe cap at the discharge port of a petrochemical device, as shown, includes a first connecting rope 1, a second connecting rope 4, and a universal connecting ring 7. A switching valve 10 is provided on the discharge pipe 9. The first connecting rope 1 and the second connecting rope 4 are connected through the universal connecting ring 7, and the ends of the two ropes away from the universal connecting ring 7 are fixedly connected to the pipe cap 8 and the discharge pipe 9 respectively.

[0022] Specifically, at both ends of the first connecting rope 1 in the length direction, a first wire locking device 2 and a second wire locking device 3 are respectively connected. The two rotating parts of the universal connecting ring 7 are of D-ring structure. One end of the first connecting rope 1 passes through the inlet hole on the first wire locking device 2, then passes through a set of D-rings of the universal connecting ring 7, and then passes through the outlet hole and is fixed by the locking mechanism on the first wire locking device 2. Thus, one end of the first connecting rope 1 is connected to one set of D-rings of the universal connecting ring 7 through the first wire locking device 2, and the end of the first connecting rope 1 away from the universal connecting ring is fixedly connected to the pipe cap 8 through the second wire locking device 3; one end of the second connecting rope 4 is connected to the second set of D-rings of the universal connecting ring 7 through a third wire locking device 5, and its connection method is the same as that of the first connecting rope 1, which will not be elaborated here. The end of the second connecting rope 4 away from the universal connecting ring 7 is connected to the discharge pipe 9 through a fourth wire locking device 6, and the connection position of the two is on the discharge pipe 9 at the water inlet end of the switching valve 10.

[0023] In this embodiment, both the first connecting rope 1 and the second connecting rope 4 are made of steel ropes with a diameter of 1.5 mm.

[0024] The technical solution adopted in this application connects the pipe cap 8 to the discharge pipe 9 through two sets of connecting ropes to prevent the loss of the pipe cap. Moreover, the two sets of connecting ropes are connected through the universal connecting ring 7. When disassembling or installing the pipe cap 8, the rotation of the pipe cap 8 will not cause the connecting ropes to twist and deform, improving the service life of the components. And when installing the pipe cap, it avoids the problem of loosening caused by the rotation of the pipe cap 8 driven by the twisting of the connecting ropes.

[0025] The above is only the preferred embodiment of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements can still be made, and these improvements should also be regarded as the protection scope of the present invention.
