The decay resistance of ball valve made of plastic is better than conventional ball valve, and fabricating cost is cheap, and shortcoming is that the macromolecular material moisture absorption is strong, and the heatproof anti-pressure ability is low, and is easily aging.Though ceramic ball valve decay resistance and high temperature resistant property are better, anti-pressure ability height, complex manufacturing technology, fabricating cost costliness, anti-knock shock resistance poor performance.Ball valve made of plastic and ceramic ball valve all exist the shortcoming of operational safety deficiency, are very limited in the application.Titanium alloy ball valve anti-knock shock resistance, it is ageing-resistant that resistance to compression is high temperature resistant.The performance of the acetic acid of anti-nitric acid one class strong corrosive medium is outstanding, but the not corrosion of strong corrosive medium such as anti-sulfuric acid, fabricating cost is higher.The prior art of similar titanium alloy ball valve also has corrosion resisting alloy valves such as monel alloy ball valve, your alloy ball valve of mattress section nickel.Its common trait is that valve body, spherical closure member and valve rod are all made by the noble metal alloy material monolithic; and in strong corrosive medium series, do not have a wide spectrum corrosion resistance; keep away the passive situation of unavoidable " sitting in the right seat ", be difficult to realize large-scale production in batches, can't reduce cost significantly.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of anti-corrosion Float ball valve of wide spectrum that almost all shows extremely strong stability in various acidity or alkali electroless medium is provided.
The purpose of this utility model is achieved through the following technical solutions.
The anti-corrosion Float ball valve of a kind of wide spectrum, it is made up of critical pieces such as side valve body, middle valve body, valve seat, spherical closure member, valve rod, sealing gasket, filler, pressing plate, handle, double-screw bolt and nuts, described valve body is divided into the structure of three formulas, between each piecemeal, be provided with valve seat and sealing gasket, carry out two seals.Described spherical closure member and valve rod adopt that flat tenon is loosening to be connected.
The anti-corrosion Float ball valve of wide spectrum keeps in full accord with prior art aspect structure length and flange Conncetion cimension, sealing together is set between each piecemeal of forming valve body, to improve the reliability of using, allowing spherical closure member and valve rod keep loosening is connected, simultaneously to working surface clinkering one deck nickelio surface hardener alloy of contact mediums such as spherical closure member and valve rod, to improve corrosion resistance.It has reduced the consumption of valuable alloy material and nickel element, has reduced cost, has realized large-scale production in batches.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Embodiment
Referring to accompanying drawing, form the Float ball valve of three formula valve body structures by two side valve bodies 1 and middle valve body 2.Ball valve also can be made two formulas valve body structure of (claiming separable type again).Their structure length and flange Conncetion cimension are all in full accord with conventional ball valve.Establish valve seat 3 and sealing gasket 7 two seals between side valve body 1, the middle valve body 2, and reliably connect, to improve operational safety by double-screw bolt 11, nut 12.Valve body can be flange-type, welding type, clamp band type and thread type with being connected of pipeline.Spherical closure member 4 and valve rod 5 employings loosening connection of flat tenon, under the effect of pressure medium, spherical closure member 4 floats between import and export valve seat 3, floats towards a side of outlet valve seat, and the realization one-way sealing helps reducing to operate moment of torsion, improves working life.
The handle 10 that turns clockwise, valve rod 5 is followed and is turned clockwise, and the flat tenon of valve rod by its lower end drives spherical closure member 4 and reaches closed position, and ball valve is closed.Be rotated counterclockwise handle 10, ball valve is opened, the orientation of handle indication is the orientation of spherical closure member 4 runners.Between handle 10 and pressing plate 9, be provided with ball valve and close positive stop with open position.
Valve body, spherical closure member, valve seat, valve rod, filler and sealing gasket are the overcurrent element of contact medium.Valve seat, filler and sealing gasket are made by the very stable teflon of physics and chemical property.The material of the valve body of metal overcurrent element, spherical closure member and valve rod selects just to have determined the anti-corrosion feature of ball valve.Different with the prior art that adopts corrosion resistant alloy material integral manufacturing metal overcurrent element, way of the present utility model is: selecting the plain cast steel of charcoal is the blank of metal overcurrent element, and it is not crisp firmly, has enough structural strengths.On the working surface of overcurrent element, the thick nickelio surface hardener alloy of compound one deck 1.0-1.20mm, the surface hardening alloy has the high hardness of HRc61-68, extremely strong physics and chemical stability.It gives overcurrent element with good characteristic such as wear-resisting, anti-corrosion, high temperature resistant and anti-oxidant, tolerates the corrosion of almost various acidity or alkali electroless medium.Inside nominal diameter is smaller or equal to 300mm, and nominal pressure all can adopt said method to obtain the wide spectrum corrosion resisting property smaller or equal to the ball valve of 6.4MPa.
Compared with prior art, the alloy material that consumes of the working surface of the utility model overcurrent element Average out to the former about 15%. And the nickel element content in the alloy material exceeds up to 70-90% The former is more than 1 times. Owing to adopt high-temperature vacuum clinkering technology, avoided built-up welding, spray welding process common The composition dilution phenomenon and peel off, the defectives such as crackle, pore. Thin hardened layer can be thick can be thin, densification Firmly. Therefore, the utility model technology can make metal overcurrent element and polytetrafluoroethylene (PTFE) valve seat, fill out Material, sealing gasket have the wide spectrum corrosion resisting property that is complementary.
