Abstract
The utility model discloses a kind of elastic packing butterfly valves, it include valve body, butterfly plate and valve rod, resilient seal surface is used between the valve body and butterfly plate, the resilient seal surface is U-loop sealing ring, U-loop sealing ring compensates sealing surface with elastic packing, the sealing performance of valve is effectively increased, also prevents excessive hardness sealing from causing the abrasion of sealing surface, keeps valve seal more reliable effectively.
Description
Technical field
The utility model relates to butterfly valve field, specifically a kind of elastic packing butterfly valve.
Background technique
Butterfly valve, is a kind of simple regulating valve of structure, and the butterfly valve that can be used for the switch control of low pressure pipeline medium refers to butterfly
Plate is disk, and a kind of valve of open and close is reached around valve shaft rotation.Butterfly valve is widely used in metallurgy, oil and gas chemical industry, city
On political affairs pipeline, it is used as and adjusts flow and truncation fluid use.General butterfly valve by self structure influenced can only positive pressure bearing and seal,
For the floating valve seat Bidirectional pressure butterfly valve then developed because simply preventing valve seat from revealing using O-ring seal, sealing performance is obvious
It is bad.
Summary of the invention
The purpose of this utility model: in order to overcome the drawbacks of the prior art, the utility model provides a kind of valve base sealing
Elastic packing butterfly valve of good performance.
The technical solution of the utility model includes: including valve body, butterfly plate and valve rod, bullet is used between the valve body and butterfly plate
Property sealing surface, the resilient seal surface be U-loop sealing ring.
By adopting the above technical scheme, U-loop sealing ring compensates sealing surface with elastic packing, effectively increases valve
Sealing performance also prevents excessive hardness sealing from causing the abrasion of sealing surface, keeps valve seal more reliable effectively.
The further setting of the utility model: U-loop sealing ring includes that two on the outside of curved face part and curved face part are straight
Line portion, the curved face part and butterfly plate form sealing cooperation.
Using above-mentioned further setting, curved face part and butterfly plate form elastic sealing and cooperate.
The further setting of the utility model: U-loop sealing ring uses full austenite resisto material.
Further it is arranged using above-mentioned, which has effective stress resistance, further enhances sealing performance.
The further setting again of the utility model: valve body includes left valve barrel and right valve barrel, the part of the right valve barrel
It penetrates in left valve barrel and is welded to connect, be provided with annular groove on the axial direction between the left valve barrel and right valve barrel, the U-loop is close
Seal is installed in annular groove.
Using above-mentioned setting further again, U-loop sealing ring installation site is rationally designed, is made easier for installation.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model specific embodiment；
Fig. 2 is the enlarged diagram in the utility model Fig. 1 at A；
Wherein, valve body 1, butterfly plate 2, valve rod 3, U-loop sealing ring 4, curved face part 41, straight line portion 42, left valve barrel 11, right valve barrel
12, annular groove 13.
Specific embodiment
A kind of elastic packing butterfly valve as shown in Figure 1 and Figure 2 includes valve body 1, butterfly plate 2 and valve rod 3, valve body and butterfly plate
Between use resilient seal surface, resilient seal surface be U-loop sealing ring 4, U-loop sealing ring 4 includes curved face part 41 and song
Two straight line portions 42 in 41 outside of face, curved face part 41 and butterfly plate 2 form sealing cooperation.Two straight line portions 42 are that curved face part 41 mentions
For brace foundation, curved face part 41 and butterfly plate 2 form elastic seal pair when valve is closed.
U-loop sealing ring 4 has good mechanicalness using the full austenite resisto material of titanium stabilizedization processing
Can, it is highly suitable as elastic seal ring use.
Valve body 1 includes left valve barrel 11 and right valve barrel 12, and the part of right valve barrel 12 penetrates in left valve barrel 11 and is welded to connect, left
Annular groove 13 is provided on axial direction between valve body 11 and right valve barrel 12, U-loop sealing ring 4 is installed in annular groove 13, curved surface
The sealing that is in contact with butterfly plate 2 is then exposed in portion 41, and the contact of contact left valve barrel 11 1 of straight line portion 42 1 of U-loop sealing ring 4 is right
It is firm to also help installation while being easily installed U-loop sealing ring 4 for valve body 12, split type valve body structure.In addition, valve
If 1 monolithic construction of body then opens up annular groove 13 on 1 inner wall of valve body, for U-loop sealing ring 4 to be packed into.
