Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

Referring to fig. 1 to 3, the present invention provides a novel stainless steel flange butterfly valve, which comprises: the structure includes: valve body 1, valve rod 2, reducing gear box 3, hand wheel 4, supplementary handle 5, valve body 1 is connected with reducing gear box 3 through the valve rod 2 at middle part, hand wheel 4 is installed at the front end of reducing gear box 3, supplementary handle 5 is installed at the top of valve rod 2, valve body 1 includes: the valve plate comprises a valve plate 11, a joint cavity 12, a driving rod 13, a sealing lug 14 and a supporting bottom groove 15, wherein the outer edge of the valve plate 11 is movably connected with the inner groove of the joint cavity 12, the sealing lugs 14 are arranged on the surfaces of flanges on two sides of the joint cavity 12, the middle part of the joint cavity 12 and the supporting bottom groove 15 form an integrated structure through welding, the driving rod 13 is connected with a valve rod 2 at the top, the inner grooves of the movable rod at the bottom of the valve plate 11 and the supporting bottom groove 15 are mutually nested, the joint cavity 12 is made of 316L stainless steel, and the 316L is widely applied to the chemical industry due to excellent corrosion resistance.

Foretell actuating lever 13 is connected with valve rod 2, carries out the work of opening and shutting, and be equipped with in actuating lever 13 middle part with adjust pole 114 complex hole, conveniently directly control through supplementary handle 5 for overall control's wholeness is stronger, and sealed effect is better.

The valve plate 11 includes: plate body 111, dredge and flow curb plate 112, supplementary circle 113, adjust pole 114, regulating spindle 115, second actuating lever 116, plate body 111 is outer along being equipped with supplementary circle 113, dredge and flow curb plate 112 through the support of second actuating lever 116 and the logical groove swing joint that plate body 111 was seted up, adjust pole 114 through regulating spindle 115 and second actuating lever 116 mechanical connection, adjust the middle part that pole 114 runs through valve rod 2, and be connected with the supplementary handle 5 of installing at valve rod 2 top, supplementary circle 113 is domatic structure, and it is the biggest near plate body 111 one end thickness, and outside highly gently reduces, second actuating lever 116 is equipped with more than two, is annular array and arranges, and second actuating lever 116 is the range of layer and is connected with regulating spindle 115.

The movement of the second driving rod 116 is controlled by the adjusting shaft 1115, the flow dredging side plate 112 is firstly controlled to be opened at the initial stage of opening and closing, so that water flow in the joint cavity 12 flows firstly, sand and stones at the side seams can be firstly taken out, and meanwhile, the water hammer effect caused by too fast opening and closing is reduced.

When in use:

the valve body 1 is connected with the reduction gearbox 3 through the valve rod 2, and the reduction gearbox 3 is driven to rotate through the hand wheel 4 to control the valve plate 11 to open and close.

Because the poor condition of quality of water, pile up the grit easily at plate body 111 periphery, the grit influences plate body 111's life easily, consequently can cooperate through the auxiliary handle 5 at top at the in-process that opens and shuts:

when needing to open, open the supplementary handle 5 at top for adjusting pole 114 drives regulating shaft 115 rotatory, makes second drive rod 116 to the central shrink, and the earial drainage curb plate 112 of side is opened, and rivers pass through supplementary circle 113, and the grit that supplementary circle 113 surface was cut is discharged in advance under the rapid flow of rivers, then opens the valve plate through hand wheel 4, more laborsaving when opening.

When the valve body 1 is closed, the hand wheel 4 rotates, the plate body 111 is closed firstly, then the dredging side plate 112 is closed through the auxiliary handle 5, the water hammer effect caused by sudden closing can be avoided, the efficiency can be improved when the valve body is closed, and the valve body 1 is protected better.
