Description
Technical field
The utility model relates to a kind of cover parts, more particularly, and particularly a kind of compound valve pocket.
Background technique
Wear-resisting compound valve pocket in producing petrochemical industry is because of work under bad environment in use, generally there is extremely strict requirement, first in the selection of its material, outer surface requires that hardness can not be better than rotating shaft or bearing, otherwise then can cause the wearing and tearing of rotating shaft or bearing, but too low being easy to again of material hardness causes the erosion of compound valve pocket inner flow passage, corrosive wear is serious, just need roll over dress after short-term job to change, seriously reduce its working life, secondly, compound valve pocket outer surface is generally circle, certain difficulty is there is when connecting with other component, and be difficult to assembling, just interference fit need be taked, but this kind of method inconvenience changes use for a long time, particularly at oil, the production field such as petrochemical industry and Coal Chemical Industry, working environment is mainly coal, it is long for dead time that compound valve pocket repairs replacing at every turn, affect continuous operation, and this compound valve pocket operating ambient temperature is generally up to 415 DEG C, working environment is quite severe, in high temperature corrosion environment like this, the compound valve pocket that prior art is produced is difficult to bear corrosion under this kind of environment and wearing and tearing, working life is very short, greatly have impact on the progress of work, add cost of production.
Therefore, how to provide that not only one corrosion-resistant but also wear-resistant, long service life, fixing compound sleeve can be stablized again and become those skilled in the art's problem demanding prompt solution.
Model utility content
The technical problems to be solved in the utility model is for providing a kind of compound valve pocket, this compound valve pocket is by its structural design, good anticorrosive anti-wear effect and operating life can be had for fields such as oil, petrochemical industry and Coal Chemical Industries for a long time, and folding can be facilitated to repair assembling.
A kind of compound valve pocket, comprise compound valve sleeve body, described compound valve sleeve body is open circles taper valve pocket and jacket wall is provided with uniform runner hole, and this compound valve sleeve body is steel compound valve sleeve body and its inwall is provided with hardstanding, and described hardstanding is amorphous material hardstanding.
Preferably, described hardstanding is CO2 gas shielded arc welding hardstanding.
Preferably, described hardstanding thickness is 5.5-6.5mm.
Preferably, described hardstanding hardness is HRC52-56.
Preferably, described runner hole be horn-like through hole and the large end of described horn-like through hole near jacket wall inwall.
Preferably, described compound valve sleeve body jacket wall outer wall is provided with bayonet socket.
The invention has the beneficial effects as follows: this compound valve pocket, by arranging amorphous material hardstanding at conical inboard wall, can make this compound valve pocket have good anticorrosive anti-wear effect for fields such as oil, petrochemical industry and Coal Chemical Industries for a long time; Meanwhile, by arranging runner hole and arrange bayonet socket at cover outer wall on casing wall, to achieve between these compound valve pocket with other component stable connects, and folding can be facilitated to repair assembling.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiment of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to the accompanying drawing provided.
Fig. 1 is the axial sectional view of the utility model compound valve pocket;
Fig. 2 is the utility model compound valve pocket A-A place sectional view;
Fig. 3 is the utility model compound valve pocket B-B place sectional view.
Embodiment
Technological scheme in the application is understood better in order to make those skilled in the art person, below in conjunction with the accompanying drawing in the embodiment of the present application, technological scheme in the embodiment of the present application is clearly and completely described, obviously, described embodiment is only some embodiments of the present application, instead of whole embodiments.Based on the embodiment in the application, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all should belong to the scope of the application's protection.
See accompanying drawing 1, accompanying drawing 2 and accompanying drawing 3, present embodiments provide a kind of compound valve pocket, comprise compound valve sleeve body, this compound valve sleeve body is open circles taper valve pocket and jacket wall 1 is provided with uniform runner hole 2, this compound valve sleeve body is steel compound valve sleeve body and its inwall 101 is provided with hardstanding 3, and hardstanding (3) is amorphous material hardstanding.
In the present embodiment, steel compound valve sleeve body jacket wall 1 inwall 101 arranges hardstanding 3, by rush at mixed fluid grinder do inwall 101 on hardstanding 3 is set, make this compound valve sleeve body jacket wall 1 inwall 101 corrosion-resistant stronger under complex working condition, and use more wear-resistant and more wear-resistant, significantly improve the working life of product.For reaching above-mentioned effect further, described hardstanding 3 is amorphous material hardstanding.
Runner hole 2 be horn-like through hole and the large end of described horn-like through hole near jacket wall 1 inwall 101.In the present embodiment, runner hole 2 be provided with interlaced arrangement two row and often row be evenly equipped with 12.Not only this kind of mode of execution can ensure the demand of firm connection but also can maintain the required linking intensity requirement of this compound valve pocket itself.
In the present embodiment, the processing mode of hardstanding 3 is the process of CO2 gas shielded arc welding, CO2 gas shielded arc welding compares with arc weldings such as manual electric arc welding, the electronic welderings of submerged arc, the current density of CO2 weldering is large, electric arc heat utilization ratio is higher, and postwelding does not need scarfing cinder, and heat is concentrated, weldment hot area is little, therefore is out of shape little; And use weld seam hydrogen content during CO2 weldering few, resistance to cracking is good, weld joint mechanical performance is good, can be observed electric arc and molten bath situation, be not easily partially welded during welding, suitable all-position welding, easy grasp, CO2 weldering is usually used in carbon steel and low alloy steel, can carry out all-position welding, CO2 gas price is cheap, and power consumption is few.Therefore, CO2 gas shielded arc welding stiff dough treated side is set in the present embodiment and has that manufacturing efficiency is high, welding deformation is little, welding quality is good, easy and simple to handle, adaptable and the feature that cost is low.Consider that in the present embodiment, hardstanding 3 thickness is 5.5-6.5mm, stiff dough treated side 3 hardness HRC52-56 in order to obtain best price/performance ratio again.
For more stable realization fixing this compound valve pocket, in the present embodiment, described compound valve sleeve body 1 outer wall 102 is provided with bayonet socket 4.
Above a kind of combination valve cover provided by the utility model is described in detail.Apply specific case herein to set forth principle of the present utility model and mode of execution, the explanation of above embodiment just understands method of the present utility model and core concept thereof for helping.Should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model principle, can also carry out some improvement and modification to the utility model, these improve and modify and also fall in the protection domain of the utility model claim.
