Disclosure of Invention

The utility model aims at the above-mentioned problem that prior art exists, provide a magnetism dirt separator, solved and made trouble, the problem of easy wearing and tearing.

The purpose of the utility model can be realized by the following technical proposal:

magnetic dirt separator, including being the cylindric shell that has the inner chamber, connecting in the shell sleeve pipe and wear to establish in the sleeve pipe and be rodlike magnetic core, magnetic core upper end be fixed with stifled cap, the shell is including the last casing that adopts plastics to make, goes up casing top center and runs through and be provided with the connecting hole, the connecting hole includes the linkage segment, its characterized in that, the linkage segment internal fixation have the copper sheathing, the centre bore of copper sheathing is equipped with the internal thread, sleeve pipe upper end threaded connection is in the lower extreme of copper sheathing, stifled cap lower extreme threaded connection is in the upper end of copper sheathing, the connecting hole still includes the cooperation section that is linked together with the linkage segment lower extreme, is equipped with mechanical seal structure between sleeve pipe and the cooperation section.

During assembly, the copper sleeve is firstly placed into the connecting hole at the top of the upper shell, the outer peripheral surface of the copper sleeve is matched with the connecting section on the inner wall of the connecting hole, and then the sleeve is inserted into the shell with the inner cavity. The copper sleeve in the magnetic dirt separator is separately arranged at the connecting section to play the role of connecting the sleeve with the blocking cap, the internal thread made of plastic which is originally molded integrally is replaced, and the separate processing and installation of the copper sleeve are more convenient in the production and manufacturing process, and the toughness of the copper sleeve is far higher than that of plastic, so that the copper sleeve is not easy to wear in the use process, and the service life is greatly prolonged.

The connecting hole still includes the cooperation section that is linked together with the linkage segment lower extreme, and when the external screw thread that the sleeve pipe set up through upper end portion and copper sheathing threaded connection were fixed, the partly of sleeve pipe upper end still cooperated with the cooperation section, and with be provided with mechanical seal structure between the cooperation section, consequently makes this magnetism dirt separator's leakproofness strengthen greatly.

In the magnetic dirt separator, the upper shell is integrally formed outside the copper sleeve in an injection molding mode.

The copper bush replaces the internal thread made of the plastic of the original injection molding integrated molding, so that the problems that the die sinking of the internal thread is inconvenient and the precision is not high due to the insufficient toughness of the plastic material in the production and manufacturing process are solved, the copper bush is made of the copper material and is not easy to deform in a high-temperature environment, the water leakage phenomenon cannot be caused, and the sealing performance is greatly improved.

In the above magnetic dirt separator, the inner wall of the connecting section is provided with at least one connecting groove, the outer side of the copper sleeve is provided with at least one annular connecting part, and the connecting part is embedded in the connecting groove.

The copper sleeve is fixed with the connecting groove through the matching of the connecting part and the connecting groove, so that the copper sleeve is more stably installed in the upper shell, and the structure is firmer.

In the magnetic dirt separator, the sleeve is a copper pipe.

If adopt plastic molding then need certain wall thickness to guarantee, can lead to the magnetism core surface to keep away from magnet along with the increase of wall thickness to take place the condition that magnetism reduces, the sleeve pipe texture in this magnetism dirt separator is copper material, chooses for use copper material to reduce the wall thickness, thereby the magnetism core is close to surface magnet, makes magnetism strengthen greatly.

In foretell magnetic dirt separator, the cooperation section internal diameter be greater than the linkage segment internal diameter, the sleeve pipe outside is equipped with the bulge loop, the side is equipped with annular slot on the bulge loop, mechanical seal structure including locating the sealed pad in the annular slot and connecting in the fitting surface between cooperation section inner wall and the linkage segment inner wall, sealed pad cooperatees with the fitting surface and forms sealedly.

The annular groove internal fixation has sealed the pad, and the height that highly is higher than the annular groove of sealed pad, because the cooperation end internal diameter is greater than the linkage segment internal diameter, and the bulge loop external diameter is greater than the linkage segment internal diameter, consequently when the installation sleeve pipe, the fitting surface between linkage segment inner wall and the cooperation section inner wall supports and presses on annular groove top side and gasket for sealed pad produces the compression to with the same height of annular groove, makes the leakproofness between sleeve pipe and the connecting hole strengthen greatly.

In the magnetic dirt separator, the matching surface is provided with an annular water stopping part, the cross section of the water stopping part is triangular, and the water stopping part is abutted against the upper side surface of the sealing gasket.

When the sleeve is installed, the annular water stop part on the matching surface is pressed against the sealing gasket to force the sealing gasket to be further compressed, so that the sealing reliability between the sleeve and the connecting hole is further improved.

In the magnetic dirt separator, the side part of the convex ring is provided with an annular mounting groove, the mechanical sealing structure further comprises a sealing ring arranged in the annular mounting groove, and the sealing ring abuts against the inner wall of the matching section to form sealing.

The outer side surface of the convex ring is provided with an annular mounting groove, a sealing ring is arranged in the annular mounting groove, and when the sleeve is mounted, the outer side surface of the convex ring and the sealing ring in the annular mounting groove are abutted against the inner wall of the fitting surface, so that further sealing is completed under the condition that the sealing gasket is sealed, a double-sealing effect is formed, and the sealing performance is further improved.

In the magnetic dirt separator, the outer side of the upper end of the sleeve is integrally and fixedly connected with the annular retaining shoulder, and the annular retaining shoulder is abutted against the surface of the lower port of the matching section.

When the sleeve is installed, the sleeve is connected and fixed with the copper sleeve internal thread, the annular blocking shoulder is abutted against the surface of the lower port of the matching section to limit, the sleeve and the copper sleeve internal thread are prevented from being installed too deeply, and the annular blocking shoulder is abutted against the surface of the lower port of the matching section to further enhance the sealing performance between the sleeve and the end part of the upper shell.

Compared with the prior art, the magnetic dirt separator breaks the routine, the copper sleeve is separately arranged at the connecting section, the effect of connecting the sleeve and the blocking cap is achieved, the original internal thread made of plastic which is molded integrally by injection is replaced, the internal thread which is molded integrally by injection is complicated and troublesome in die opening, the precision cannot be better mastered, and the copper sleeve is separately arranged, so that the overall production and manufacturing of the magnetic dirt separator are simple and convenient; secondly the internal thread of the integrated into one piece that moulds plastics easily produces the deformation under high temperature environment, and the toughness of plastics is not enough, has leaded to easily appearing the phenomenon of leaking in the use, and the toughness of copper and resistant high temperature are far stronger than plastics, and difficult wearing and tearing, deformation are in the use, so set up the copper sheathing alone and can make life increase greatly after connecting the short department.
