Abstract
The utility model discloses a sealing structure of a double-eccentric soft-sealing butterfly valve. The sealing structure of the double-eccentric soft-sealing butterfly valve comprises a butterfly plate, a pressing ring and a seal ring arranged between the butterfly plate and the pressing ring, and is characterized in that the section of the seal ring is in the shape of T, two grooves are formed in the butterfly plate and the pressing ring respectively, and the two ends of the T-shaped head portion of the seal ring are connected to the interior of the butterfly groove and the interior of the pressing ring respectively in a clamped mode. The sealing structure of the double-eccentric soft-sealing butterfly valve changes the structure of the seal ring, and improves practicability and reliability of the valve.
Description
Technical field
The utility model relates to a kind of sealing configuration of butterfly valve, relates to particularly a kind of sealing configuration of two eccentric soft close butterfly valves.
Background technique
Butterfly valve is again Flap valve, is a kind of modulating valve simple in structure, and the switch that also can be used for the low pressure pipeline medium is simultaneously controlled.Butterfly valve refers to that closure member (flap or butterfly plate) is disk, rotates to reach a kind of valve of open and close around valve shaft, and on pipeline, main rising cut off and throttling action.The butterfly valve open-shut device is a discoidal butterfly plate, and the axis around himself in valve body rotates, thereby reaches the purpose that opens and closes or regulate.Butterfly valve is applicable to carry on the pipeline of various corrosivity, non-corrosive fluids medium in the engineering systems such as producer, coal gas, rock gas, liquefied petroleum gas (LPG), town gas, cold and hot air, chemical industry smelting and generation environment-friendly, for regulating and block flowing of medium.
Owing to being Flow-rate adjustment for gas or liquid, so its sealability is extremely important.The sealing configuration of existing two eccentric soft close butterfly valves, be that the one side by seal ring is placed on butterfly plate, and another side is to push down with pressure ring, then tightens with screw; Valve is in the process opened and closed, and the form that the valve seat on sealing surface and valve body produces extruding guarantees sealing.But there is following deficiency in this sealing configuration: the keying of valve produces warp and loosening while easily making the sealing surface of seal ring and valve seat extruding.
The model utility content
The purpose of this utility model is to provide a kind of sealing configuration of two eccentric soft close butterfly valves, to solve the above-mentioned problems in the prior art.
The technological scheme that the utility model provides is as follows:
A kind of sealing configuration of two eccentric soft close butterfly valves, comprise that a butterfly plate, a pressure ring and are located in the seal ring between butterfly plate and pressure ring, it is characterized in that: described seal ring cross section is T shape, be provided with one first groove by edge on butterfly plate, pressure ring is provided with one second groove by edge, and the two ends of the head of the T shape of seal ring are connected in respectively in the first groove and the second groove.
In preferred embodiment of the present utility model, also be provided with for regulating the screw of the tightness between pressure ring and butterfly plate.
In preferred embodiment of the present utility model, the lateral margin outwardly convex of this butterfly plate forms a circle flange, the zone that the bottom of this flange and the angle between lateral margin are place, ，Gai right angle, right angle forms a breach, and this breach is in the bottom of flange, form the first groove by the lateral margin place.。
Due to the sealing configuration of the soft close butterfly valve of two bias, be that the one side by seal ring is placed on butterfly plate, another side is to push down with pressure ring, then tightens with screw; Valve is in the process opened and closed, the form that the afterbody of seal ring and the valve seat on valve body produce extruding guarantees sealing, and the head two ends of seal ring are located at respectively in the first groove and the second groove, while preventing the keying of valve, produce warp and loosening when the afterbody of seal ring and valve seat extruding.For this reason, after having changed the structure of seal ring, strengthened practicability and the reliability of valve.

Embodiment
Specific embodiment of the utility model, referring to figs. 1 through Fig. 4, a kind of sealing configuration of two eccentric soft close butterfly valves, comprise a butterfly plate 1, a pressure ring 2 and a seal ring 3.
Lateral margin 13 outwardly convexs of this butterfly plate 1 form a circle flange 11, and the zone that the bottom 12 of this flange 11 and the angle between lateral margin 13 are place, ，Gai right angle, right angle forms a breach 14.This breach 14 is in the bottom 12 of flange 11, by lateral margin 13 places' formation one first grooves 15.
Referring to Fig. 2, the cross section of seal ring 3 is T shape, and the one end is outstanding outwardly, forms sealed department 31, and sealing section 31 be V-arrangement, from inside to outside, in the middle part of upper and lower two side direction, dwindle gradually.The upper and lower both sides of end inwardly are respectively upper convex portion 32 and lower protuberance 33.
During assembling, referring to Fig. 4, seal ring upper convex portion 32 is arranged on to 15 li of first grooves of butterfly plate 1, lower protuberance 33 is arranged on 21 li of second grooves of pressure ring 2, then uses screw 4 adjusting elasticities.Valve is in the process opened and closed, and sealed department 31 guarantees sealing with the form that valve seat on valve body produces extruding, and upper convex portion 32 and lower protuberance 33 be while preventing the keying of valve, and the sealed department 31 of seal ring produces warp and loosening during with the valve seat extruding.For this reason, after having changed the structure of seal ring, strengthened practicability and the reliability of valve.
Above are only a specific embodiment of the present utility model, but design concept of the present utility model is not limited to this, allly utilizes this design to carry out the change of unsubstantiality to the utility model, all should belong to the behavior of invading the utility model protection domain.
