Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned deficiency, and it is less to propose a kind of volume, and easy accessibility is installed easily reliable sealing high temperature, high pressure magnetic levitation type liquid level meter access hole packoff.
The utility model is realized with the following method.
High temperature, high pressure magnetic levitation type liquid level meter access hole packoff has circle tube form shell body, the bottom of circle tube form shell body inwall has along the circumferential direction, the cross section is the annular groove of rectangle, on the circle tube form shell body, at the bottom of annular groove, be evenly equipped with four radial direction through hole, have in the annular groove and match with annular groove, the cross section is the combination annulus of rectangle, the external diameter of combination annulus equates with the bottom land place diameter of a circle of annular groove, the internal diameter of combination annulus is littler 8～12 millimeters than the internal diameter of circle tube form shell body, the combination annulus is connected to form by symmetrical six segmental arcs, a left side, the both ends of the surface of the interlude in three segmental arcs of right symmetry are parallel to each other and perpendicular with the plane of symmetry of combination annulus, in the circle tube form shell body, there is the cylindrical envelope core of two sections ladders the top of annular groove, the external diameter of the big section of cylindrical envelope core diameter matches with the circle tube form shell body internal diameter, cylindrical envelope core diameter is than between the outer wall of segment and the circle tube form shell body inwall annular gap being arranged, above the combination annulus, the annular pressure ring is arranged, the external diameter of pressure ring matches with the internal diameter of circle tube form shell body, the wall thickness of pressure ring matches with above-mentioned annular gap, cross section above the pressure ring is an isosceles triangle, there is the disc pressing plate below of annular groove, the pressing plate external diameter matches with the circle tube form shell body internal diameter, between pressing plate and the envelope core connecting screw rod is arranged.
During use, the upper end of the utility model circle tube form shell body is welded on high temperature, the lower end of high pressure magnetic levitation type liquid level meter tubular table body, cylindrical envelope core diameter than the outer wall of segment and the annular gap between the circle tube form shell body inwall in the airtight and watertight padding of filling soft graphite, connecting screw rod between rotary pressure plate and the envelope core allows the envelope core move downward, compress the airtight and watertight padding between envelope core and housing, realize sealing of the present utility model, particularly, seals on the core high pressure in the tubular table body when acting on, the envelope core moves downward, make airtight and watertight padding be pressed in above the pressure ring downwards, can allow airtight and watertight padding more closely be close to the wall that seals between core and housing above the isosceles triangle of pressure ring, produce self sealss, make sealing more reliable.When maintenance, the connecting screw rod between pressing plate and the envelope core is withdrawed from rotation earlier, take out pressing plate from the lower end of tubular table body, from circle tube form shell body, four uniform radial direction through hole stretch into rigid rod at the bottom of the annular groove, release two relative interludes of combination annulus in the annular groove earlier, take out from the lower end of tubular table body, release other four again, take out from the lower end of tubular table body, then can take out the pressure ring in the circle tube form shell body successively from the circle tube form shell body lower end, cylindrical envelope core and soft graphite airtight and watertight padding, can take out high temperature from the circle tube form shell body lower end then, the float that is connected with permanent magnet that lost efficacy in the high pressure magnetic levitation type liquid level meter tubular table body, be reentered into the new float that is connected with permanent magnet, put into cylindrical envelope core more successively, soft graphite airtight and watertight padding and pressure ring, the combination of combination annulus is placed in the annular groove, put into pressing plate, screw bolt, realize high temperature again, the sealing of the lower end access hole of high pressure magnetic levitation type liquid level meter tubular table body.
The utility model volume is less, and easy accessibility is installed easily, and sealing is reliable.
Below in conjunction with accompanying drawing, the utility model is further described.
