Description
Technical field
The utility model relates to valve technology field, in particular to a kind of wear resistance ball valve.
Background technique
The valve that mineral industry generally uses is metal hard-sealing ball valve, use existing history for many years, although metal hard-sealing ball valve is through the improvement of structure and material, but by the restriction of metallic material attribute, the demand of the bad working environments such as more and more higher wearing and tearing, deep-etching can not be adapted to, be mainly reflected in working life short, leak serious, greatly have impact on the stability of system cloud gray model.Valve be by change MEDIA FLOW through valve passage time drainage area realize control overflow, in pipeline, the medium of normal circulation is when by valve, due to the flip-flop of its drainage area, thus have also been changed the flow velocity of medium, the flow direction, pressure reduction and even temperature, energy obtains release at this or is further compressed, medium defines very complicated motion at valve cavity, and as eddy current, cavitation erosion, water hammer etc., these motions are the principal elements causing valve wear, corrosion and erosion.In order to adapt to the needs of special operation condition, the ore pulp particularly walked in mineral industry valve is the gas-solid mixing medium of high hardness solid particle or the solid-liquid mixed media containing highly corrosive composition, under certain temperature and pressure, in pipeline, the medium of fast flowing can increase the weight of wearing and tearing to valve, corrosion and erosion, so be proposed higher requirement to aspects such as wear-resistant, the corrosion resistance of valve and abrasion resistances.
Current valve manufacture enterprise is all by have employed high-velocity spray at spheroid and valve base surface, surfacing high hardness hard alloy layer, or the modes such as high hard alloy such as built-up welding Si Taili, the life-span of valve is made to obtain certain raising, but because the spheroid of wear resistance ball valve and the surface hardness of valve seat are all close with medium, or exceed few, and the corrosivity of coating metal material to medium does not play the function resisted, do not have real erosive wear resistant, corrosion resistant use effect, and valve is once after finding leakage, larger defect can be there is in a short period of time.
Model utility content
The purpose of this utility model is that providing a kind of improves the wear resistance ball valve realizing erosive wear resistant by circulating channel structure, during to solve the use of existing ball valve, the media such as ore pulp particle impact large to valve seat or valve body and outlet port, and coated with hard alloy-layer is difficult to the real problem reaching resistance to erosion.
For realizing the utility model object, the technological scheme adopted is: a kind of wear resistance ball valve, comprise valve body and the valve seat, the spheroid that are positioned at valve body, spheroid offers spheroid through hole, the outer wall of valve seat is attached on the overall inwall of valve body, and the hole wall of the inwall of valve seat and spheroid through hole forms the circulation passage of venturi tube structure.
Venturi tube structure comprises straightway and is positioned at the diffuser at straightway two ends, its channel internal diameter is made to have certain change, the diameter of passage is imported and exported two ends from it and is diminished gradually to middle spheroid, namely the pressure in valve body is changed accordingly, thus prevent medium the washing away valve such as ore pulp particle, reduce its wearing and tearing to valve seat.
Further, the surface of described circulation passage is provided with ceramic layer.Like this on the basis changing channel design, the part contacted with circulation medium at ball valve is all set to structural ceramic material, the chemical stability of pottery and extreme hardness, make this valve have higher wear-resistant, corrosion-resistant, erosive wear resistance, and thermal insulation is good, thermal expansion is little, make this valve durable in use, reliability is high, long service life, is titanium alloy valve and Monel valve 2-4 times, reach wear-resistant antiscour, corrosion resistant object, guarantee that product valve body breakage does not occur.
Further, described valve body comprises left valve barrel and right valve barrel, and is connected with valve gap therebetween; The valve seat be positioned on left valve barrel and right valve barrel inwall is respectively left valve seat, right valve seat, and spheroid is between left valve seat and right valve seat.For convenience detach, the also more convenient circulation passage being processed to form venturi tube structure.
Further, described spheroid coordinates with valve seat rotary seal, left valve seat, right valve seat is provided with the arc sealing surface coincide with spheroid.Guarantee that the secondary physical dimension of spheroid and valve base sealing is coincide consistent, arc sealing surface is abradant surface, and spheroid and valve seat are to grinding the sealability reached.
Further, the valve rod arranged that to link with spheroid is also comprised.Valve rod, as actuator, drives spheroid to rotate the keying realizing valve.
The beneficial effects of the utility model are, become the circulation passage of venturi tube structure with spherical by valve seat in valve body, Venturi principle is adopted to improve traditional channel design, the erosive wear resistant of valve is realized by channel design, adopt merely hard alloy layer to improve compared with its wearability with prior art, more effectively prevent ore pulp granule medium to valve seat, washing away of valve body and valve export end, ceramic layer also can be set and improve its wear-resistant performance such as corrosion-resistant further, meet the corrosion-resistant requirement of high abrasion, preferably be applicable to the granule medium of high hardness, or have soft particle but have the medium of corrosion, the particularly ore pulp of mineral industry, ball valve tool of the present utility model has great advantage, such architecture advances not only increases its erosive wear resistant, and structure is simple, good seal performance, less in certain inside nominal diameter scope inner volume, lightweight, material consumption is few, installation dimension is little, easy and simple to handle, be easy to Operation and maintenance.
