Abstract
The present invention relates to a strong oxidation corrosion resisting titanium butterfly valve which comprises a valve body and a valve rod which is dynamically sealed and matched with the inner cavity of the valve body through a butterfly plate connected with the valve rod through a fastening member. The outside extending end of the valve rod is connected with a valve controlling device. The valve body is made from a ZTA2 or TA2 titanium material. The valve rod is made from a TC4 or TA2 titanium material. The butterfly plate is made from the ZTA2 or TA2 titanium material. The fastening member is made from the TC4 or TA2 titanium material. All the parts contacting strong oxidation corrosion media in the butterfly valve of the present invention are made from titanium materials, which causes the butterfly valve to have the advantages of good corrosion resisting performance, strong oxidation corrosion media resistance, very long time use, no need of replacement generally, no influence on continuous production, no corroded leakage, safety and reliability.
Description
Technical field: the present invention relates to a kind of butterfly valve.
Background technique: in fields such as petrochemical industry, soda acid, chlorine, chemical fertilizer and desalination of sea water produce, all have strong oxide etch medium, be easy to medium pipeline and valve corrosion.General anticorrosion valve all adopts cast iron or alloy material manufacturing, and anti-strong oxygen corrosion is relatively poor, must often change, and can influence bigger to ask for something quantity-produced field.And if general valve is corroded and leaks out strong oxide etch medium, have influence on safety in production easily.
Summary of the invention: at the deficiencies in the prior art, it is long to the invention provides a kind of service time, safe and reliable titanium butterfly valve with powerful oxidation corrosion resistance.
The present invention includes valve body and valve rod, the butterfly plate and the body cavity motive sealing that are connected on the valve rod by fastening piece cooperate, the valve rod overhanging end then is connected with the valve control device, valve body adopts ZTA2 or TA2 titanium material to make, valve rod adopts TC4 or TA2 titanium material, butterfly plate adopts ZTA2 or TA2 titanium material, and fastening piece adopts TC4 or TA2 titanium material; Sealing pair between butterfly plate and valve body adopts nonmetal resistant material and TC4 or the stacked mode of TA2 titanium material to constitute the multi-level sealing pair of soft or hard, perhaps adopts titanium material spring ring to constitute hard sealing pair.
All parts that contact strong oxide etch medium all adopt the titanium material in the butterfly valve of the present invention, and corrosion resistance is good, can the powerful oxidation corrosion resistance Korrosionsmedium, service time is very long, does not generally need to change, and can not influence continuous production, and the seepage that can not be corroded, safe and reliable.
The present invention also can be provided with packing layer and corresponding filler gland between the overhanging end of valve rod and valve body, this filler gland adopts TC4 or TA2 titanium material to make.So a small amount of medium enters in the slit between valve rod and valve body, also can seepage not go out better reliability.
When using in the production that partly can produce crystallization, can be with insulation jacket outside valve body, this insulation jacket adopts TC4 or TA2 titanium material to make.Utilize chuck to be incubated, can eliminate the medium crystallization, manufacturing efficiency is higher.
Further specify the present invention below in conjunction with drawings and Examples.
Description of drawings: Fig. 1 is embodiment's a main structure schematic representation;
Fig. 2 is the I portion enlarged diagram of Fig. 1;
Fig. 3 is another form schematic representation of Fig. 2.
Embodiment: as shown in Figure 1, valve rod 2 places valve body 1 to be rotationally connected, and the butterfly plate 3 and the valve body 1 inner chamber motive sealing that are connected on the valve rod 2 by fastening piece 4 cooperate, and valve rod 2 overhanging ends then are connected with valve control device 5.Valve body 1 adopts ZTA2 or TA2 titanium material to make, and valve rod 2 adopts TC4 or TA2 titanium material, and butterfly plate 3 adopts ZTA2 or TA2 titanium material, and fastening piece 4 adopts TC4 or TA2 titanium material.Present embodiment is provided with packing layer 6 and corresponding filler gland 7 at the overhanging end and 1 of the valve body of valve rod 2, and this filler gland 7 adopts TC4 or TA2 titanium material to make.Also be with insulation jacket 8 outside valve body 1, this insulation jacket 8 adopts TC4 or TA2 titanium material to make.
According to the needs of actual design, when valve body 1 and butterfly plate 3 employing forging types, available ZTA2 titanium material, available TA2 titanium material is produced in welding.The hardness of TC4 titanium material is higher, and general valve rod 2 can adopt TC4 titanium material, and intensity is higher and can bear than high pulling torque.In the reality, filler gland 7 and fastening piece 4 generally also adopt TC4 titanium material.The valve control device 5 of present embodiment is a manually operated type, also can use different forms such as pneumatic, electronic certainly.
