Description

High-sealing sanitary butterfly valve

Technical Field

The utility model belongs to the technical field of the butterfly valve, more specifically say, relate to a high sealed sanitary-grade butterfly valve.

Background

The butterfly valve is a regulating valve with simple structure, and the butterfly plate rotates around the valve rod to open or close, and mainly plays a role in cutting off and throttling on a pipeline.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to provide a high sealed sanitary-grade butterfly valve, it can realize the high sealing performance of butterfly valve, and prolongs the life of butterfly valve.

The utility model discloses a high sealed sanitary-grade butterfly valve, including two valve bodies, two be equipped with the sealing washer between the valve body, be equipped with the butterfly plate in the sealing washer can dismantle on the butterfly plate and be equipped with the handle, be equipped with two seal assembly on two circular terminal surfaces of butterfly plate respectively, seal assembly includes joint portion and sealing.

Preferably, each sealing component clamping part comprises two clamping grooves formed in the circular end face of the butterfly plate.

Preferably, every sealing assembly's sealing part is including setting up two locating pieces on the circular terminal surface of butterfly plate, two can dismantle between the locating piece and be equipped with the pivot, the cover is equipped with sealed the pad in the pivot, sealed pad orientation a side end face of butterfly plate central line is equipped with two fixture blocks.

Preferably, the diameter of the circumscribed circle of the sealing gasket is larger than that of the circumscribed circle of the butterfly plate.

Preferably, the sealing gasket is composed of a fixing section close to the positioning block and an elastic section far away from the positioning block.

Compared with the prior art, the utility model has the advantages of:

1. through the sealed setting of filling up of seal assembly, form the sealing layer in two circular terminal surfaces departments of butterfly plate, make the butterfly valve form the sealed isolation of three-layer, improved the sealed effect in the butterfly valve.

2. Through the setting of sealed pad, sealed pad can laminate with the butterfly plate, wraps up the butterfly plate, has reduced the area of contact between butterfly plate and liquid, has reduced the attachment of impurity on the butterfly plate in the liquid, and then has reduced the butterfly plate when closing the butterfly valve and the wearing and tearing between the valve body, has guaranteed the sealed effect of butterfly plate to the valve body, has prolonged the practical life of butterfly valve.

3. Through the setting of sealed fixed section of filling up, guaranteed sealed stability of filling up, avoid sealed the pad to receive liquid and take place deformation when assaulting, influence the parcel effect to the butterfly plate.

4. Through the cooperation between sealing assembly draw-in groove and the fixture block, the stability of sealed pad at the butterfly plate side has further been improved.

Detailed Description

The first embodiment is as follows: referring to fig. 1-4, a high-sealing sanitary butterfly valve includes two valve bodies 10, the two valve bodies 10 are detachably connected by four locking bolts 12, a sealing ring 11 is disposed between the two valve bodies 10, a butterfly plate 13 is disposed on the sealing ring 11, two sealing assemblies are disposed on two circular end faces of the butterfly plate 13, a rotating end and a connecting end are integrally formed on an outer peripheral side of the butterfly plate 13, wherein the connecting end penetrates through the two valve bodies 10 and extends to an external space, and a handle 17 is sleeved on a portion of the connecting end located outside the valve bodies 10.

In this embodiment, the seal assembly includes a snap-in portion and a seal portion.

The sealing part comprises two positioning blocks 14 arranged on the circular end face of the butterfly plate 13, a rotating shaft is detachably arranged between the two positioning blocks 14, a sealing gasket 15 matched with the butterfly plate 13 is sleeved on the rotating shaft, the sealing gasket 15 comprises a fixed section close to the positioning blocks 14 and an elastic section far away from the positioning blocks 14, and two clamping blocks are further arranged on the end face, facing the butterfly plate 13, of one side of the sealing gasket 15;

further, the circumscribed circle diameter of the sealing gasket 15 is larger than that of the butterfly plate 13.

By arranging the sealing component sealing gaskets 15, sealing layers are formed at the two circular end faces of the butterfly plate 13, so that three layers of sealing isolation are formed in the butterfly valve, and the sealing effect in the butterfly valve is improved;

further, when the butterfly valve is opened and liquid flows in the valve body 10, the liquid impacts the sealing gasket 15 to approach the direction of the butterfly plate 13, so that the sealing gasket 15 is attached to the butterfly plate 13, the butterfly plate 13 is wrapped, the contact area between the butterfly plate 13 and the liquid is reduced, the attachment of impurities in the liquid to the butterfly plate 13 is reduced, the abrasion between the butterfly plate 13 and the valve body 10 when the butterfly plate 13 is closed is further reduced, the sealing effect of the butterfly plate 13 on the valve body 10 is ensured, and the practical service life of the butterfly valve is prolonged;

further, sealed 15 of filling up comprises fixed section and elastic segment two parts, through the setting of fixed section, has guaranteed sealed 15 of filling up's stability, takes place deformation when avoiding sealed 15 of filling up to receive liquid impact, influences the parcel effect to butterfly plate 13.

Sealing assembly's joint portion is including seting up two draw-in grooves on the circular terminal surface of butterfly plate 13, through the cooperation between draw-in groove and sealing part fixture block 16, has further improved the stability of sealed pad 15 at butterfly plate 13 side.
