Embodiment Construction

[0029] In order to further understand the present invention, the best embodiment of the butterfly valve of the present invention is as attached Figures 1 to 13 As shown, it at least includes a valve body 1, a leak-proof element 2 and a valve 3:

[0030] Such as figure 1 and 2 The aforementioned valve body 1 is provided with a valve stem hole 10, and the aforementioned valve stem hole 10 penetrates downward from the valve seat 11 to the valve stem groove 13 below the valve through hole 12, so that the valve stem 14 is arranged in the valve stem hole 10, and The top of the aforementioned valve stem 14 can be combined with the handle 15 , and the aforementioned valve stem 14 passes down through the valve through hole 12 and passes through the central hole 30 of the valve 3 to be positioned in combination with the aforementioned valve stem groove 13 . The annulus wall 120 of the aforementioned valve through hole 12 is an integrated polygonal-like joint flange 121 that can be pr...

Abstract

The invention provides a butterfly valve. The butterfly valve at least comprises a valve body, a leakage stopping element and a valve, the valve body is provided with a valve through hole, and the valve through hole can be combined with the leakage stopping element firstly; the leakage stopping element is provided with a surrounding surface, the surrounding surface is provided with corresponding upper and lower combination holes of the valve, one or more first leakage stopping surrounding parts are integrally formed on the inner ring walls of the upper and lower combination holes, and one or more second leakage stopping surrounding parts are integrally formed on the inner sides of the upper and lower combination holes and positioned on the inner wall of the valve hole; the valve is provided with an upper positioning element and a lower positioning element which are integrally formed, after the leakage stopping element is combined with the valve, the first leakage stopping surrounding parts and the second leakage stopping surrounding parts can achieve the effects of sealing and no leakage, and the valve can be opened and closed more smoothly.

Description

technical field [0001] The invention relates to a structural innovation of a butterfly valve, in particular to an innovative design that can ensure smooth opening and closing of the butterfly valve. Background technique [0002] Existing butterfly valves, such as China Taiwan Patent No. M517277 "Double Leap Butterfly Valve Structure", the combination of the valve body and the disc plate must be pierced by means of the upper and lower valve stems, that is, the aforementioned butterfly plate and the valve seat do not have any The points and surfaces that are fixed and fixed make the butterfly plate and the valve seat seem to have no interaction, and it also causes the butterfly plate to come out of the valve seat after being subjected to a large water pressure, causing a problem of failure. [0003] For this reason, the inventor of this case has accumulated many years of experience in designing and manufacturing various valves, studied the structural problems of the aforementi...
