Abstract
The utility model discloses a nickel sealed iron ball eccentric valve which is characterized in that a nickel seal element (1) is arranged at the contact position of a valve body(2) of the iron ball eccentric valve and a valve plate(3), and the nickel seal element(1)matched with the corresponding part of the valve plate(3). The nickel sealed iron ball eccentric valve can remain stainless in various complicated environment with fluid media and is good in sealing effect. Meanwhile, the sealing surface is unlikely to fall off, thereby greatly improving the service life of the valve and reducing the using cost of the valve. The nickel sealed iron ball eccentric valve can effectively protect the normal operation of the pipeline system.
Description
Technical field
The utility model relates to a kind of magnesium iron eccentric valve, and especially a kind of valve body is the magnesium iron eccentric valve of nickel sealing, belongs to mechanical manufacturing field.
Background technique
Present eccentric valve sealing surface generally adopts copper base or stainless steel-based sealing surface embedding technique to handle, in pipeline under the complicated flowing medium environment, contain particularly that stainless steel-based sealing surface can quicken to get rusty under the situation of electrolyte or strong acid or highly basic, copper base sealing surface can quicken to get rusty in the bigger medium of carbon dioxide content.After sealing surface gets rusty, can cause valve seal to lose efficacy, pipeline can't run well; Embedding technique in use has obscission under the not too tight situation of preparation process technology, cause whole valve invalidation, and pipeline can't run well, and must change valve again, increases user's operating cost and economic loss.
The model utility content
At the deficiency that prior art exists, technical problem to be solved in the utility model provides a kind of magnesium iron eccentric valve of nickel sealing, to solve the easy problem of quickening to get rusty, have obscission of sealing surface in the prior art.
For solving the problems of the technologies described above, the magnesium iron eccentric valve of nickel sealing of the present utility model, its technological scheme of taking is: the sealing station at magnesium iron eccentric valve valve body and valve plate is provided with the nickel Sealing, and the corresponding site of nickel Sealing and valve plate matches.
The magnesium iron eccentric valve of above-mentioned nickel sealing is provided with the built-up welding groove with the valve plate position contacting on its valve body, and the nickel Sealing is welded to connect by built-up welding groove and valve body.
The magnesium iron eccentric valve of this nickel sealing surface, the nickel content of its sealing surface reaches 99.99%, can keep stainless in the liquid media environment of various complexity, and sealing effect is better; Simultaneously; because the pure nickel sealing material is to adopt advanced argon arc welding technology built-up welding on valve body; be welded as organic whole with valve body; the possibility that sealing surface does not come off; improved the working life of valve greatly; reduce the user cost of valve, can effectively protect the normal operation of pipe-line system.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the sectional view of A-A part among Fig. 1.
Embodiment:
As depicted in figs. 1 and 2, the magnesium iron eccentric valve of this nickel sealing, it is provided with built-up welding groove 4 with valve plate 3 position contacting on magnesium iron eccentric valve valve body 2, on the built-up welding groove 4 of valve body 2, nickel Sealing 1 is set, nickel Sealing 1 is welded to connect by built-up welding groove 4 and valve body 2, and nickel Sealing 1 matches with the corresponding site of valve plate 3.
The magnesium iron eccentric valve of this nickel sealing, the making method of its sealing surface is: at first open in the position that magnesium iron eccentric valve valve body need seal and make the built-up welding groove, reach 99.99% nickel built-up welding sealing surface then with content by the argon arc welding technology, and accomplish sealing surface dense structure, non-oxidation, require to process the correct shape of sealing surface again according to drawing, the outermost nickel content of its sealing surface will reach 99.99%.
The magnesium iron eccentric valve of this nickel sealing surface, the nickel content of its sealing surface reaches 99.99%, can keep stainless in the liquid media environment of various complexity, and sealing effect is better; Overcome because of the defective stainless steel-based under the bigger situation of electrolyte, strong acid, highly basic, carbon dioxide content, that copper base sealing surface can quicken to get rusty; Simultaneously; because the pure nickel sealing material is to adopt advanced argon arc welding technology built-up welding on valve body; be welded as organic whole with valve body; the possibility that sealing surface does not come off; the phenomenon that can come off in the sealing surface using process that has prevented to inlay; improve the working life of valve greatly, reduced the user cost of valve, can effectively protect the normal operation of pipe-line system.
Claims (2)
1, a kind of magnesium iron eccentric valve of nickel sealing, it is characterized in that: the contact position at magnesium iron eccentric valve valve body (2) and valve plate (3) is provided with nickel Sealing (1), and nickel Sealing (1) matches with the corresponding site of valve plate (3).
2, the magnesium iron eccentric valve of nickel according to claim 1 sealing is characterized in that: go up with valve plate (3) position contacting at its valve body (2) and be provided with built-up welding groove (4), nickel Sealing (1) is welded to connect by built-up welding groove (4) and valve body (2).
