Abstract
The utility model relates to a two eccentric butterfly valves of high pressure, which comprises the following components: a valve body, and a valve cor, a valve sea, the valve rod, the pressure disk, clamp plate and U type elastic component, water conservancy diversion chamber and control hole are established to the valve body, water conservancy diversion chamber and the coaxial distribution of valve body, control hole axis is perpendicular and crossing with the valve body axis, the valve rod is installed on the valve body through controlling the hole, and with control the coaxial distribution in hole, the valve rod end is located the water conservancy diversion intracavity of valve body and is connected with the case, and the case equallys divide the water conservancy diversion chamber for flowing in the section and the section that flows, the disk seat is located the outflow section in water conservancy diversion chamber and offsets with the case, U type elastic component at least two and with the section water conservancy diversion intracavity wall sliding connection that flows, the clamp plate passes through the pressure disk and installs the outflow section department in the water conservancy diversion chamber. The utility model discloses an aspect can effectually satisfy the needs that use under the multiple high -pressure pipeline environment, on the other hand can effectually avoid leading to the fact because of the atress deformation the dead phenomenon of card of valve rod because of the valve rod to the stability in use and the reliability of effectual improvement butterfly valve.
Description
Technical field
The utility model relates to a kind of pressure valve equipment, is exactly a kind of high pressure double eccentric butterfly valve.
Background technique
Current butterfly valve is control valve mechanism important in multiple delivery line, have and apply very widely, but find in actual use, current butterfly valve is due to the reason of self structure, use under only using with no pressure or low pressure line environment, and when applying with pressure duct, very easily there is seals damaged and cause dielectric leakage and valve rod etc. that deformation occurs because pressure is excessive in current butterfly valve, and cause the stuck fault such as cannot normally to run of butterfly valve to occur, therefore in order to improve using scope and the stability in use of butterfly valve, in the urgent need to developing a kind of novel dish valve arrangement, with the needs that satisfied reality uses.
Model utility content
For the deficiency that prior art exists, the utility model provides a kind of high pressure double eccentric butterfly valve, the dish valve product that this model utility is more traditional, structural strength is large, good seal performance, anti-pressure ability, anticorrosive ability of anti-deformation are strong, thus the needs used under on the one hand effectively can meeting multiple pressure duct environment, can effectively avoid on the other hand because valve rod to cause the stuck phenomenon of valve rod because of stress deformation, thus effective stability in use and the reliability improving butterfly valve.
To achieve these goals, the utility model realizes by the following technical solutions:
A kind of high pressure double eccentric butterfly valve, comprise valve body, spool, valve seat, valve rod, platen, pressing plate and U-shaped elastic component, valve body establishes diversion cavity and control hole, diversion cavity and valve body coaxially distribute, control hole axis is vertical with valve axis and crossing, valve rod is arranged on valve body by control hole, and coaxially distribute with control hole, valve stem end is positioned at the diversion cavity of valve body and is connected with spool, and diversion cavity is divided into inflow segment and flows out section by spool, valve seat is positioned at the outflow section of diversion cavity and offsets with spool, U-shaped elastic component at least two is also slidably connected with outflow section diversion cavity inwall, U-shaped elastic component one of them and valve seat side end face offset, another and pressing plate offset, pressing plate is arranged on the outflow section place of diversion cavity by platen, and platen, pressing plate and U-shaped elastic component are ring structure.
Further, described spool and contact surface of valve seat place establish sealing joint strip.
Further, described valve rod is separately connected by tapered roller bearing with between control hole.
The dish valve product that the utility model is more traditional, structural strength is large, good seal performance, anti-pressure ability, anticorrosive ability of anti-deformation are strong, thus the needs used under effectively can meeting multiple pressure duct environment on the one hand, can effectively avoid on the other hand because valve rod to cause the stuck phenomenon of valve rod because of stress deformation, thus effective stability in use and the reliability improving butterfly valve.
Accompanying drawing explanation
The utility model is described in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is the utility model structural representation.
Embodiment
The technological means realized for making the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with embodiment, setting forth the utility model further.
A kind of high pressure double eccentric butterfly valve as described in Figure 1, comprise valve body 1, spool 2, valve seat 3, valve rod 4, platen 5, pressing plate 6 and U-shaped elastic component 7, valve body 1 establishes diversion cavity 8 and control hole 9, diversion cavity 8 and valve body 1 coaxially distribute, control hole 9 axis is crossing with valve body 1 axes normal, valve rod 4 is arranged on valve body 1 by control hole 9, and coaxially distribute with control hole 9, valve rod 4 end is positioned at the diversion cavity 8 of valve body 1 and is connected with spool 2, and diversion cavity 8 is divided into inflow segment 81 and flows out section 82 by spool 2, valve seat 3 is positioned at the outflow section 82 of diversion cavity 8 and offsets with spool 2, U-shaped elastic component 7 at least two is also slidably connected with outflow section 82 diversion cavity 8 inwall, U-shaped elastic component 7 one of them and valve seat 3 side end face offset, another and pressing plate 6 offset, pressing plate 6 is arranged on outflow section 82 place of diversion cavity 8 by platen 5, and platen 5, pressing plate 6 and U-shaped elastic component 7 are ring structure.
Further, described spool 2 establishes sealing joint strip 10 with valve seat 3 surface of contact place.
Further, described valve rod 4 is connected with another to be held by tapered roller axle 11 between control hole 9.
The dish valve product that the utility model is more traditional, structural strength is large, good seal performance, anti-pressure ability, anticorrosive ability of anti-deformation are strong, thus the needs used under effectively can meeting multiple pressure duct environment on the one hand, can effectively avoid on the other hand because valve rod to cause the stuck phenomenon of valve rod because of stress deformation, thus effective stability in use and the reliability improving butterfly valve.
The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
