Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with the accompanying drawings detailed description of the invention of the present utility model is described in detail.The example of these preferred implementations is illustrated in the accompanying drawings.The embodiment of the present utility model shown in accompanying drawing and described with reference to the accompanying drawings is merely exemplary, and this utility model is not limited to these embodiments.
At this, it can further be stated that, in order to avoid having obscured this utility model because of unnecessary details, illustrate only in the accompanying drawings and according to the closely-related structure of scheme of the present utility model and/or process step, and eliminate other details little with this utility model relation.
Shown in ginseng Fig. 1 and Fig. 2, a kind of gate valve, including: valve body 1, valve circle 2 and valve rod 3, one end of described valve body 1 is provided with import 4, the other end of described valve body 1 is provided with outlet 5, described import 45 is located on the same line with outlet, described valve body 1 be arranged over valve gap 6, be provided with pad 7 between described valve gap 6 and valve body 1.Being connected by fixture 8 between described valve gap 6 and valve body 1, in the present embodiment, described fixture 8 is bolt and nut.Described valve circle 2 is arranged in valve body 1, and described valve rod 3 extends vertically in valve body 1, and described valve rod 3 epimere is screw rod, and hypomere is polished rod.One end of described valve rod 3 is provided with the flashboard 9 matched with valve circle 2, is provided with upper seal support 10, spacer ring 11, filler 12 and gland 13 between described valve gap 6 and valve rod 3, and described upper seal support 10 welds with valve gap 6 phase.In the present embodiment, described filler 12 is made up of graphite, described gland 13 be arranged over pressing plate 14, the eyelet bolt 15 being arranged above matching with pressing plate 14 of described valve gap 6, it is connected by bearing pin 16 between described eyelet bolt 15 and valve gap 6, the movable joint nut 17 being arranged over matching with eyelet bolt 15 of described pressing plate 14, disc spring set 18, disk spring 19 and disc spring seat 20, described pressing plate 14 be arranged over valve stem nut 21, clamp nut 22 and lubricating cup 23, described valve stem nut 21 be arranged over handwheel 24, described handwheel 24 be arranged over locking nut 25, the sealing surface weld deposit Si Taili hard alloy of described gate valve.
