Drawings
FIG. 1 is a schematic view of a weld joint leakage repairing structure for a polymerization production line of the present invention.
The temperature probe comprises a container body 1, a container body 2, a temperature probe sleeve 3, a protective cover 4, an air filling pipe 5 and a cover plate.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and the following detailed description.
As shown in fig. 1, the utility model provides a welding seam trapping structure for polymerization production line, including vessel 1 and the temperature probe sleeve pipe 2 of welding on vessel 1 surface, simultaneously in temperature probe sleeve pipe 2, temperature probe detects the temperature in temperature probe sleeve pipe 2, install safety cover 3 additional at vessel 1, safety cover 3 is in temperature probe sleeve pipe 2 end cover in it, the 2 other ends of temperature probe sleeve pipe pass safety cover 3 and stretch outside safety cover 3, when the welding seam seepage appears in the position that safety cover 3 and vessel 1 are connected like this, toward the 3 intussuseptions of safety cover pack protective gas (protective gas is argon gas or helium), avoid the special medium contact welding high temperature area in the vessel 1. Specifically, the protective cover 3 is manufactured in advance when the container body 1 is manufactured. Specifically, the protective cover 3 is welded at the position of the container body 1 corresponding to the thickness of the steel plate, so that larger leakage points caused by the penetration of the steel plate are avoided, and potential safety hazards are eliminated.
As an example, the protection cover 3 is hemispherical for easy welding. Specifically, the temperature probe sleeve 2 is horizontally arranged, one end of the temperature probe sleeve 2 is welded on the container body 1, the other end of the temperature probe sleeve 2 is welded on the protection cover 3, and the axis of the temperature probe sleeve 2 and the axis of the protection cover 3 are on the same straight line.
As an example, in order to fill the protective gas into the protective cover 3, an air filling pipe 4 is provided in the protective cover 3, and the air filling pipe 4 is communicated with the interior of the protective cover 3. Specifically, the gas filler tube 4 is welded to the protective cover 3. Specifically, the gas filling pipe 4 is obliquely arranged on the protective cover 3, so that gas filling is facilitated. Specifically, after the protective gas is filled, the opening of the gas filling pipe 4 is sealed by the cover plate 5.
Particularly, the utility model discloses a principle is that prior art is because of there being special medium to take place the reaction or increase the potential safety hazard of leaking in welding process, and this type of maintenance mending-leakage can not normally go on, wants to construct special medium in the must evacuation container and wash qualified rear and can go on.
