The coupler consists of a left coupler (1), a rightcoupler (4), a left cover (2) and a right cover (3); the left end of the left coupler (1) is equipped with left coupler threads (8) and the right end is a concave sphere (7) which is fit with the left cover (1); the right end of the right coupler (4) is equipped with right coupler threads (5) and the left end is a convex sphere (6) which is fit with the right cover (3); the right cover (3) and the right coupler (4) are fit in the left cover (2); the right cover (3) is equipped with external cuniform bosses of the right cover (10) and a operating handle (11); the right cover is equipped with internal cuniform bosses of the left cover (9), the number of which is equal to that of the external cuniform bosses (10) of the right cover; the proper number is 2 to 4. The invention is characterizedby long service life, excellent rightness and greatly reduced production cost; at the same time the replacement times of the invention are reduced and the production efficiency is promoted.
Description
Technical field
The invention belongs to steelmaking technical field, the quick-replaceable joint device that particularly a kind of ladle argon-blown is used.
Background technology
Rapid-acting coupling at present is a kind of tube stub that does not need tool using can realize rapid dismounting again, and it has advantages such as compact construction, volume are little, in light weight, high pressure resistant, interchangeable.This tube stub uses lightly nimble, clarity, the hydraulic pressure that is widely used in metallurgy, mine, forging and pressing, oil, lathe, chemical industry equipment and various agricultural machine, piping systems such as pneumatic transmission and lubricating fluid conveying thoroughly realize safe and efficient leak free quick conversion.In being badly in need of frequent disassembling pipe, particularly adapt to.The ladle argon-blown quick joint generally adopts the hydraulic quick coupler standardized component, but because liquid steel temperature is at 1550-1680 ℃ in the ladle, rubber gasket high-temperature heating in the hydraulic quick coupler is easily aging, particularly after the vacuum-treat of VD stove, the ladle argon-blown quick joint is that a stove one changes substantially, has greatly increased production cost.
Summary of the invention
The objective of the invention is at the problems referred to above and defective, and the ladle argon-blown that designs a kind of high temperature resistant, long service life, good sealing effect is with the hydraulic quick coupler easy aged hydraulic quick coupler standardized component that replaces being heated.
The object of the present invention is achieved like this: it is to be made of left joint, right connector, left side cover and right cover, the left-hand end of left side joint is provided with screw thread, right-hand member is concave spherical surface and is set with left side cover, the right-hand end of right connector is provided with screw thread, and left end is protruding sphere and is set with right cover that right cover and right connector are sleeved in the cover of a left side, the right side puts and is provided with right outer wedge shape boss of cover and operation handle arm, a left side puts and is provided with wedge shape boss in the cover of a left side, and wedge shape boss and the outer wedge shape boss quantity of right cover equate in the cover of a left side, are advisable for 2-4.The present invention is owing to be provided with the concave, convex sphere in the end of left and right joint, and left and right on left and right joint puts and is respectively equipped with in the cover of a left side wedge shape boss outside the wedge shape boss and right overlapping, so make the steel spherical joint replace rubber gasket, mode of connection changes spiral holding out against into, makes joint bring up to 80 heats by 1 heat work-ing life; Adopt self-locking to hold out against overcoat, strengthened sealing effectiveness, greatly reduce production cost, reduced the replacing number of times simultaneously, improved production efficiency.
Description of drawings
Accompanying drawing 1 is a structural representation of the present invention.Accompanying drawing 2 is the structural representation of left side cover among the present invention.Accompanying drawing 3 is the vertical view of accompanying drawing 2.Accompanying drawing 4 is the structural representation of right cover among the present invention.Accompanying drawing 5 is the vertical view of accompanying drawing 4.In the accompanying drawing: 1-left side joint, 2-left side cover, the right cover of 3-, 4-right connector, 5-right connector screw thread, the protruding sphere of 6-, 7-concave spherical surface, 8-left side joint screw thread, wedge shape boss in the cover of a 9-left side, the outer wedge shape boss of the right cover of 10-, 11-operation handle arm, 12-groove.
Embodiment
That the invention will be further described is as follows below in conjunction with accompanying drawing: it is by left joint 1 for the present invention, right connector 4, left side cover 2 and right cover 3 constitute, the left-hand end of left side joint 1 is provided with left joint screw thread 8, right-hand member is concave spherical surface 7 and is set with left side cover 2, the right-hand end of right connector 4 is provided with right connector screw thread 5, left end is protruding sphere 6 and is set with right cover 3, right cover 3 and right connector 4 are sleeved in the left side cover 2, right cover 3 is provided with right outer wedge shape boss 10 of cover and operation handle arm 11, be provided with wedge shape boss 9 in the cover of a left side in the left side cover 2, wedge shape boss 9 and outer wedge shape boss 10 quantity of right cover equate in the cover of a left side, be advisable for general 2-4, one end of left side cover 2 is a hexagon, the other end is cylindrical, and right cover 3 is a truncated cone-shaped.When using the utility model, left side cover 2, left joint 1 link to each other with ladle, rightly overlap 3, right connector 4 links to each other with Argon pipe before the steel melting furnace.When right connector 4 during by the continuous precession of right cover 3, gap between the concave spherical surface 7 on the joint 1 of a left side and the protruding sphere 6 of right connector 4 constantly dwindles, when concave spherical surface 7 just overlaps with protruding sphere 6, cover outer wedge shape boss 10 in the right side of right cover 3 also just contacts with two sides that interior wedge shape boss 9 is overlapped on the left side in the left side cover 2 on the right connector 4, continue precession right connector 4, make the protruding sphere 6 of concave spherical surface 7 and right connector 4 on the left joint 1 constantly hold out against, reached good sealing effectiveness.Processed left and right cover 2,3 and left and right joint at 1,4 o'clock, and must guarantee working accuracy, smooth finish reaches, to guarantee its sealing effectiveness; Guaranteeing simultaneously has good interchangeability between each part.When the novel ladle argon-blown of installation is used hydraulic quick coupler, note holding out against between joint and the cover, hold out against degree and sealing effectiveness to strengthen it.
