Abstract
The invention relates to the technical field of wing valves, and discloses a wear resisting method for preventing a valve plate of a wing valve from being worn and a wear-resistant wing valve. Wear-resistant cobalt-base alloy coating is adopted in the method and is sprayed on a surface, which corresponds to a connecting tube 3, of the valve plate 1, catalyst 5 is stopped from flowing to the valve plate 1 so as to avoid scouring and abrading the valve plate 1, and the service life of the wing valve is prolonged. The wear-resistant wing valve comprises a shell 4, the connecting tube 3 and the valve plate 1, one end of the connecting tube 3 in the shell 4 is connected with the valve plate 1, and a cobalt-base alloy coating layer is disposed on a surface, which corresponds to the connecting tube 3, of the valve plate 1. Wear resistance of the valve plate of the wing valve can be effectively increased, the service life of the wing valve is prolonged, repair cost is reduced, and simultaneously, production efficiency is also increased.
Description
[technical field]
The present invention relates to the flutter valve technical field, relate in particular to a kind of wear-resisting method and wear-resisting flutter valve that prevents the wearing and tearing of flutter valve valve plate.
[background technique]
At present, in the prior art, common flutter valve valve plate 304 materials that adopt receive washing away of catalyzer more, and valve plate weares and teares quite serious in very short a period of time, needs often to keep in repair and change.Flutter valve is changed quite trouble, also has certain angle during installation, but also has increased many expenses.
[summary of the invention]
In order to overcome the deficiency in the background technique, the present invention provides a kind of wear-resisting method and wear-resisting flutter valve that prevents the wearing and tearing of flutter valve valve plate.Can effectively improve the wear resistance of flutter valve valve plate, increase the life-span of flutter valve, reduce maintenance cost.Also improved simultaneously manufacturing efficiency.
In order to realize the foregoing invention purpose, the scheme that the present invention adopted is:
A kind of wear-resisting flutter valve that prevents the wearing and tearing of flutter valve valve plate comprises: housing 4, adapter 3, valve plate 1, and an end of said housing 4 inner connecting tubes 3 connects valve plate 1, and said valve plate 1 is provided with the cobalt base alloy sprayfused coating with adapter 3 corresponding one sides.
A kind of wear-resisting method that prevents flutter valve valve plate wearing and tearing adopts wear resistance cobalt base alloy coating, is sprayed on valve plate 1 and takes over 3 corresponding one sides, prevents catalyzer washing away and wear and tear the life-span of prolongation flutter valve valve plate 1.
Because adopt aforesaid technological scheme, the present invention has following superiority:
A kind of wear-resisting method and wear-resisting flutter valve that prevents flutter valve valve plate wearing and tearing can effectively improve the wear resistance of flutter valve valve plate, increases the life-span of flutter valve, reduces maintenance cost.Also improved simultaneously manufacturing efficiency.
[description of drawings]
Fig. 1 is the work schematic representation of the wear-resisting flutter valve of the present invention;
Among the figure: 1: valve plate 2: cobalt base alloy sprayfused coating 3: take over 4: housing 5: catalyst stream is to (signal arrow mark);
[embodiment]
As shown in Figure 1, a kind of wear-resisting flutter valve that prevents the wearing and tearing of flutter valve valve plate comprises: housing 4, adapter 3, valve plate 1, and an end of said housing 4 inner connecting tubes 3 connects valve plate 1, and said valve plate 1 is provided with the cobalt base alloy sprayfused coating with adapter 3 corresponding one sides.
A kind of wear-resisting method that prevents flutter valve valve plate wearing and tearing adopts wear resistance cobalt base alloy coating, is sprayed on valve plate 1 and takes over 3 corresponding one sides, prevents catalyst stream washing away and wear and tear the life-span of prolongation flutter valve to 5 pairs of valve plates 1.
During work,Catalyst stream gets into from taking over 3 to 5, flows to valve plate 1, owing to be coated with wear resistance cobalt base alloy sprayfused coating 2 on the valve plate 1, can not wear and tear so can bear washing away of catalyzer for a long time, reduces maintenance cost, prolongs the life-span of flutter valve.
Claims (2)
1. wear-resisting flutter valve that prevents flutter valve valve plate wearing and tearing is characterized in that: comprising: housing 4, take over 3, valve plate 1, an end of said housing 4 inner connecting tubes 3 connects valve plate 1, said valve plate 1 is provided with the cobalt base alloy sprayfused coating with adapter 3 corresponding one sides.
2. wear-resisting flutter valve a kind of prevents the wear-resisting method of flutter valve valve plate wearing and tearing according to claim 1; It is characterized in that: adopt wear resistance cobalt base alloy coating; Be sprayed on valve plate 1 and take over 3 corresponding one sides, prevent catalyst stream washing away and wear and tear the life-span of prolongation flutter valve to 5 pairs of valve plates 1.
