Embodiment 1

[0029] Combine Figure 1-2 As shown, the present invention provides an online inspection separating seat three eccentric butterfly valve, including a body mechanism 100, a maintenance mechanism 200, and a fastening mechanism 300, and the body mechanism 100 includes a valve body 110, a valve plate 120 disposed in the valve body 110, mounted to The valve plate 120 and the valve shaft 130 of the valve body 110 and the valve seat 140 disposed in the inner wall of the valve body 110, the maintenance mechanism 200 includes a repair opening 210 of the valve body 110, which is provided at the maintenance port 210 and mounted in the valve. The valve cover 220 of the body 110 is coupled to the four open ring 230 of the inner wall of the valve body 110, which is formed in a screw 240 of the four-open ring 230 and a pressure plate 250 and a valve plate sealing seat 260 in the valve plate 120, and its design. When the valve occurs internally, the opening of the maintenance port 210 can be used ...

Abstract

The invention discloses an online overhaul separation seat three-eccentric center butterfly valve which comprises a body mechanism, a maintenance mechanism and a fastening mechanism. The body mechanism comprises a valve body, a valve plate arranged in the valve body, a valve shaft installed in the valve plate and penetrating through the valve body, and a valve seat arranged on the inner wall of the valve body; and the maintenance mechanism comprises a maintenance opening formed in the valve body and a valve deck arranged at the maintenance opening and installed on the valve body. According to the online overhaul separation seat three-eccentric center butterfly valve, through mutual cooperation of the body mechanism and the maintenance mechanism, when the valve seat leaks, a worker can open the valve deck, then parts of the maintenance mechanism are disassembled through the maintenance opening, and therefore the valve can be maintained quickly and conveniently; and after maintenance, the valve seat, a valve seat base plate and a compensation pad assembly can be mounted to achieve a self-positioning effect, so that the valve seat is hermetically connected in a valve plate sealing seat, and the condition of leakage after sealing is reduced.

Description

Technical field [0001] The present invention relates to the field of valve technology, and in particular, the three eccentric butterfly valves can be isolated from-line. Background technique [0002] The valve stem axis is simultaneously deviated from the center of the disc and the body center, and the valve seat turn axis has a certain angle with the valve body channel axis, referred to as a three deviate butterfly valve. [0003] The existing three eccentric butterfly valve usually occurs the inner leakage of the valve, while the existing three-ec-side butterfly valve is difficult to repair or replace the valve when the valve seat is disclosed, so that it will affect the normal use of the three eccentric butterfly valve. Inventive content [0004] The present invention is intended to address one of the technical problems present in the prior art or related art. [0005] To this end, the technical solution used in the present invention is: [0006] The separation of the three e...
