Abstract
The utility model discloses a novel butterfly valve which comprises a valve body (1) and a valve plate (2) arranged inside the valve body (1). The novel butterfly valve is characterized in that a seal ring (3) is arranged on the valve body, and the inner circumferential face of the seal ring is provided with a sealing pressing sleeve (4). The novel butterfly valve has the advantages that the seal ring is installed on the valve body, after the valve is opened, scouring force of fluid flowing through the butterfly valve on the seal ring is reduced, prolonging of service life of the seal ring is benefited, and sealing performance is good.
Description
Technical field
The utility model relates to a kind of novel butterfly valve.
Background technique
Traditional butterfly valve, its seal ring is installed on the valve plate usually, is installed on the seal ring on the valve plate, and its working life is shorter.
The model utility content
The purpose of this utility model is exactly in order to address the above problem, and a kind of novel butterfly valve is provided.
To achieve these goals, the utility model adopts following technological scheme:
A kind of novel butterfly valve, comprise valve body (1) and be located at the interior valve plate (2) of valve body (1), it is characterized in that, seal ring (3) is located on the described valve body, and valve plate corresponding surface of contact when closing seals mutually with seal ring, and sealing circle inner peripheral surface is provided with sealed pressing sleeve (4).
The beneficial effects of the utility model are: seal ring is installed on the valve body, and after Open valve, the fluid of the butterfly valve of flowing through reduces the dynamics of washing away of seal ring, be conducive to prolong the working life of seal ring, and sealability is better.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, a kind of novel butterfly valve, comprise valve body 1 and be located at valve plate 2 in the valve body 1, generally, seal ring all is arranged on the valve plate, this case then is located at seal ring 3 on the described valve body, and valve plate corresponding surface of contact when closing seals mutually with seal ring, and sealing circle inner peripheral surface is provided with sealed pressing sleeve 4.
