Description

Technical Field

[0001] The utility model relates to the field of pipes, in particular to a device for a rigid polyvinyl chloride pipe joint. Background Art

[0002] Rigid polyvinyl chloride, UPVC, also known as hard PVC, is an amorphous thermoplastic resin made by polymerization of vinyl chloride monomer and certain additives (such as stabilizers, lubricants, fillers, etc.). But strictly speaking, UPVC is hard PVC, and hard PVC is not UPVC. A rigorous and scientific discussion of UPVC should be that UPVC cannot contain or use plasticizers, while hard PVC contains plasticizers; in addition to using additives, it also adopts the method of blending and modifying with other resins to make it have obvious practical value; these resins include CPVC, PE, ABS, EVA, MBS, etc.; UPVC has high melt viscosity and poor fluidity. Even if the injection pressure and melt temperature are increased, the fluidity does not change much; in addition, the molding temperature of the resin is very close to the thermal decomposition temperature, and the temperature range for molding is very narrow, making it a difficult material to mold; polyvinyl chloride is polymerized from vinyl chloride monomer (VCM); because 57% of the mass of its molecules is chlorine; so compared with other plastics, it consumes less petroleum in the same mass.

[0003] The patent search is about a device for rigid polyvinyl chloride pipe joint (publication number CN214008462U), which relates to the field of rigid polyvinyl chloride technology, and is to solve the problem that the joints of existing rigid polyvinyl chloride pipes are inconvenient to connect and install, and inconvenient to operate.

[0004] The above patent facilitates the connection and installation of the joints of the rigid polyvinyl chloride pipe, but when the filter is cleaned, the filter is disassembled and cannot operate normally, thereby affecting the normal transportation of the solution by the rigid polyvinyl chloride pipe.

[0005] Therefore, it is necessary to invent a device for a rigid polyvinyl chloride pipe joint to solve the above problems. Utility Model Content

[0006] The utility model aims to provide a device for rigid polyvinyl chloride pipe joints to solve the problem in the background art that the filter screen cannot work normally when it is removed during cleaning, thereby affecting the normal delivery of solution by the rigid polyvinyl chloride pipe.

[0011] Preferably, a sealing cover plate is provided on the top of the counterweight block, the sealing cover plate is fixedly connected to the counterweight block, and a U-shaped handle is fixedly connected to the top of the sealing cover plate.

[0012] Preferably, fixing columns are fixedly connected at the four corners of the sealing cover plate, and there are four groups of fixing columns, which are distributed in a rectangular shape.

[0013] Preferably, the tops of the first filter box and the second filter box are provided with limiting holes, and the limiting holes match the fixing columns.

[0014] Technical effects and advantages of the utility model:

[0015] 1. By setting the first control valve, the second control valve, the third control valve, the diverter box, the first filter box, the second filter box and the confluence box, when the filter needs to be cleaned, the second control valve can be closed first, and the first control valve and the third control valve are opened normally. At this time, the solution inside the first rigid polyvinyl chloride pipe enters the second delivery pipe through the diverter box, and then enters the second filter box, and is transported to the second rigid polyvinyl chloride pipe through the fourth delivery pipe and the confluence box, and then output by the second rigid polyvinyl chloride pipe. Then the staff starts to clean the filter inside the first filter box. When the filter inside the first filter box is cleaned, the third control valve can be closed, and the first control valve and the second control valve are opened normally. At this time, the solution flows out through the first filter box. At this time, the staff can start to clean the filter inside the second filter box. When the filter inside the second filter box is cleaned, the first control valve, the second control valve and the third control valve are all opened normally to complete the cleaning of the filter, so that the staff will not affect the normal delivery of the solution by the first rigid polyvinyl chloride pipe and the second rigid polyvinyl chloride pipe when cleaning the filter;

[0016] 2. By setting a U-shaped handle, a sealing cover, a fixed column, a limit hole and a counterweight block, the staff first hooks the U-shaped handle and then pulls it upward. Because the U-shaped handle is fixedly connected to the sealing cover plate, and the four corners of the sealing cover plate are fixed with fixed columns, the fixed columns are then driven to separate from the limit holes, so that the filter net connected to the sealing cover plate through the counterweight block is pulled out, which is convenient for the staff to quickly disassemble the filter net for cleaning.
