Abstract
The invention discloses a double-eccentric sealed butterfly valve for cement industry, which comprises a valve body, a valve seat, a valve plate, a joint bearing and an elastic sealing ring, wherein the joint bearing is arranged on the valve body, the valve seat is arranged on the inner wall of the valve body, the valve seat and the valve plate are arranged in a double-eccentric mode, and the elastic sealing ring is arranged on the outer edge of the valve plate. The joint bearing is aligned flexibly, low abrasion and good sealing effect are achieved between the valve plate sealing ring and the valve seat, and the double-eccentric sealed butterfly valve can resist high temperature which can reach 300 DEG C.
Description
Technical field
The present invention relates to a kind of cement industry equipment, be specifically related to the two eccentric sealed butterfly valves of a kind of cement industry.
Background technique
Cement industry uses the operating ambient temperature of seal butterfly valve more than 300 ℃, the seal request height, bore big (common more than 1000mm), as adopt general high sealing valve cost higher, and because the operating temperature height can cause distortion to change motionless, and cement industry with single eccentric sealed butterfly valve in the course of the work, seal ring contacts and pushes with sealing surface of seat all the time, and seal ring is short working life, present domestic this suitable series products that lacks.
Summary of the invention
The objective of the invention is in order to overcome the deficiencies in the prior art, a kind of good sealing effect, the two single eccentric sealed butterfly valves of cement industry simple in structure, that wearing and tearing are little are provided.
Technological scheme of the present invention: the two eccentric sealed butterfly valves of a kind of cement industry, comprise valve body, valve seat, valve plate, joint shaft bearing and elastic seal ring, on the described valve body joint shaft bearing is installed, valve seat is arranged on the inwall of valve body, valve seat and valve plate are two eccentric settings, and elastic seal ring is located at the outer rim of valve plate.
Described elastic seal ring is preferably silicone rubber sheet material, and structure is the strip material, fixes by pressing plate, can save mould.Silicone rubber is convenient to processing, 300 ℃ of high temperature of ability, and cost low, purchase easily.Valve seat on the valve body adopts the bipyramid guiding, can guide elastic seal ring to enter valve seat, thereby alleviate wearing and tearing, simplified structure.
The present invention supports the employing joint shaft bearing, and the support loading ability is strong, aligning flexible, the deformability of compensating shaft is strong.
Described valve plate is two eccentric settings, valve plate is entered or break away from the valve seat process on the valve body, as long as angle between valve plate and the valve seat is greater than 18 °, elastic seal ring just can not contact fully with the sealing surface of valve seat, can reduce resistance effectively, alleviate wearing and tearing, improved elastic seal ring working life.
Beneficial effect of the present invention: 1, the joint shaft bearing aligning is flexible; 2, wearing and tearing are little between valve plate seal ring and the valve seat; 3, good sealing effect, it is high temperature resistant, can reach 300 ℃.
