[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model provides Figure 1-3 The high-precision four-hole pressure cover for polyester chemical fiber equipment shown in the figure is not easy to be damaged, including a fixing column 3 fixedly connected to the upper outer wall of a base 1;

[0024] A plurality of vertically penetrating holes 4 are provided between the fixed column 3 and the base 1 at equal intervals for the medium to pass through;

[0025] The uppermost sides of the inner walls at the left and right ends of the hole 4 are threadedly connected with connectors 5;

[0026] The outer wall of the upper end of the connector 5 is fixedly connected with a delivery pipe 6 to transport the medium. First, the connector 5 and the hole 4 are fixedly connected, and then the fluid or gas is transported through the delivery pipe 6 to ensure the stable operation of the equipment under high pressure and high temperature environment, thereby reducing damage to the equipment. When the polyester chemical fiber equipment is running, the four holes 4 on the pressure cover will control the flow of fluid or gas to ensure that the pressure and flow speed inside the equipment are within a safe range. The high-precision pressure cover can accurately control the size and position of the hole to achieve precise regulation of the flow of fluid or gas;

[0027] Positioning plates 8 are provided at the four corners of the circular outer wall of the connecting head 5, and upwardly opening threaded holes 7 are provided on the upper outer wall of the fixing column 3 and on the left and right sides of the hole 4. The upper outer wall of the positioning plate 8 is provided with fixing screws 9 that penetrate downward into the threaded holes 7 to limit the position of the positioning plate 8 and the connecting head 5. When fixing the connecting head 5, the positioning plate 8 and the threaded hole 7 can be aligned, and the fixing screw 9 is passed through the threaded hole 7 of the positioning plate 8 and rotated clockwise. After tightening the fixing screw 9, the position of the connecting head 5 can be fixed.

[0028] like Figure 3 As shown, a fixing ring 10 is fixedly connected between the plurality of positioning plates 8 , and a limiting ring 12 is fixedly connected to the outer wall of the upper end of the fixing column 3 to limit the position of the fixing ring 10 .

[0029] When the connector 5 is fixed inside the hole 4 and rotated, the fixing ring 10 can be clamped on the limiting ring 12 to limit the fixing range between the connector 5 and the hole 4, and the position of the welding fixing ring 10 can be adjusted according to needs.

[0030] like Figure 4As shown, a positioning groove 14 opening to the right is formed inside the right end outer wall of the fixing ring 10, and a positioning rod 13 penetrating to the left inside the positioning groove 14 is fixedly connected to the left end outer wall of the positioning plate 8 to limit the rotation distance of the positioning plate 8.

[0031] When the rotary connector 5 is connected to the hole 4 , the different threaded connection positions will cause the positioning plate 8 and the threaded hole 7 to be farther apart. At this time, the positioning plate 8 can be rotated to adjust its position to align with the threaded hole 7 .

[0032] like Figure 2 and Figure 3 As shown, multiple positioning plates 8 can be rotated under the drive of external force to adapt to the positions of corresponding threaded holes 7. There are four positioning plates 8 in total. The fixing ring 10 and the connecting head 5 are fixedly connected by welding. A limiting groove for the limiting ring 12 to be clamped is opened inside the outer wall of the lower end of the fixing ring 10.

[0033] After being fixed by the fixing screws 9 , the four positioning plates 8 can more stably limit the position of the connector 5 , and the fixed connection is performed by welding, which can avoid the occurrence of breakage and separation between the fixing ring 10 and the connector 5 .

[0034] like Figure 1 As shown, the upper outer wall of the base 1 is fixedly connected to the cover body 2, and the uppermost sides of the left and right outer walls of the connector 5 are fixedly connected to the limiting blocks 11.

[0035] The cover body 2 is provided to shield the fixing column 3 so that the position of the connector 5 is shielded by the cover body 2 to prevent the connector 5 from being broken due to contact with external objects, and the friction force when disassembling and assembling the connector 5 is increased by the limit block 11.

[0036] The implementation principle of this embodiment is: first, a fixed connection is made between the connector 5 and the hole 4, and then the fluid or gas is transported through the delivery pipe 6 to ensure the stable operation of the equipment under high pressure and high temperature environment, thereby reducing damage to the equipment. When the polyester chemical fiber equipment is running, the four holes 4 on the pressure cover will control the flow of fluid or gas to ensure that the pressure and flow rate inside the equipment are within a safe range. The high-precision pressure cover can accurately control the size and position of the holes to achieve precise adjustment of the flow of fluid or gas. When fixing the connector 5, the positioning plate 8 and the threaded hole 7 can be aligned, and the fixing screw 9 is passed through the positioning plate 8 and the threaded hole 7 and rotated clockwise. After tightening the fixing screw 9, the position of the connector 5 can be fixed.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
