Abstract
The utility model belongs to machinery valve field especially relates to a butterfly valve valve plate field. Present butterfly valve is because long -term the transport contains the more fluid of particulate matter, and when receiving large -traffic impacts of fluid, deflect easy emergence of time spent of doing of the power of receiving in the both ends of valve plate, and some take place the deformation even, influence the sealing performance of butterfly valve, especially when accurate conveyance fluid, and the accuracy of influence number certificate. The valve plate leads to a large amount of leakages because the effect of the power that receives takes place to deflect when serious, seriously influences the production progress. The utility model provides a good butterfly valve valve plate of sealing capacity, which comprises the following components: a valve body, the valve body cross sectional shape is circular, its characterized in that, and valve ear and a lower valve ear on edge valve body center pin both ends set up one respectively, the valve ear is the pot shape at the dark end, valve ear upper portion is provided with outside convex border, border thickness is 2 times of valve body thickness, the border degree of depth is the 15 -16 of the valve ear degree of depth, has solved the problem that long -time transport particulate matter fluid and flow strike the deflection deformation that the valve body produced when great.
Description
Technical field
The invention belongs to machinery valve field, particularly relate to a kind of butterfly valve plate field.
Background technique
Butterfly valve is the throttle part that fluid-transporting tubing generally uses, and valve plate is the core component of butterfly valve, plays the key effect controlling flow.Existing butterfly valve is owing to carrying for a long time containing the more fluid of particulate matter, and when impacting by fluid large discharge, the two ends of valve plate easily deflect when the effect being subject to power, what have even deforms, affecting the sealability of butterfly valve, especially when accurately carrying fluid, affecting the accuracy of data.Valve plate deflects due to the effect being subject to power, causes a large amount of leakage, have a strong impact on manufacturing schedule time serious.
Summary of the invention
The butterfly valve plate that the utility model provides a kind of airtight performance excellent, for solving institute's produced problem in above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions: the butterfly valve plate that the utility model provides a kind of airtight performance excellent, comprise valve body, described valve body sectional shape is circular, it is characterized in that, a upper valve ear and a lower valve ear are set respectively along valve body central shaft two ends, described valve ear is the pot shape at the dark end, described valve ear top is provided with outwardly edge, described edge thickness is 2 times of valve body thickness, the described edge degree of depth is the 1/5-1/6 of the valve ear degree of depth, described upper valve ear is provided with double-layer cavity, a cylindrical cavity is established on the top at the edge of described upper valve ear, a square body cavity is established in the bottom at the edge of described upper valve ear, described lower valve ear establishes a cylindrical cavity.
The beneficial effects of the utility model are:
1, one valve ear is respectively set along valve plate central shaft two ends, ensures the balance of valve opening and closing, be beneficial to valve opening size and control, ensure the sealability of valve closing.
2, this valve plate is formed in one, and overall structure is guaranteed the close type performance of valve, stops valve body and reveals generation.
3, upper valve ear inside is double layer construction, and top is cylindrical cavity, and bottom is square body cavity, both ensure that the sealability of valve plate, and has in turn enhanced valve drive forces.
