Description
Technical field
This utility model relates to valve field, particularly relates to a kind of stop valve.
Background technology
Stop valve, is also pipe valve, is one of most popular a kind of valve, and why very popular it is, be due in opening and closing process between sealing surface frictional force little, relatively durable, Lift is little, easy to manufacture, easy to maintenance, it is applicable not only to mesolow, and is applicable to high pressure.The Guan Bi principle of stop valve is, relies on valve thick stick pressure, makes valve clack sealing surface and sealing surface of seat fit tightly, and stops medium circulation.There is the defects such as structure complexity, intensity are not high, not wear-resistant, service life is short in stop valve of the prior art.
Utility model content
Technical problem to be solved in the utility model is: provide the stop valve that a kind of simple in construction, intensity are high.
nullFor achieving the above object，The technical solution adopted in the utility model is: a kind of stop valve，Including: valve body、Valve rod and valve seat，One end of described valve body is provided with import，The other end of described valve body is provided with outlet，Described valve seat is arranged in valve body，One end of described valve rod extends vertically in valve body，Described valve body be arranged over valve gap，It is connected by fixture between described valve body and valve gap，One end of described valve rod is provided with flap and the valve clack cover welded mutually with flap，It is provided with thrust pad between described valve rod and flap，It is provided with upper seal support between described valve rod and valve gap、Spacer ring、Filler and gland，Described gland be arranged over pressing plate，It is connected by eyelet bolt and nut between described pressing plate and valve gap，It is connected by bearing pin between described eyelet bolt and valve gap，The valve stem nut being arranged over matching with valve rod of described pressing plate，Described valve stem nut be arranged over handwheel，Described handwheel be arranged over plain cushion and locking nut.
Preferably, in above-mentioned a kind of stop valve, described fixture is bolt and nut.
Preferably, in above-mentioned a kind of stop valve, the epimere of described valve rod is screw rod, and hypomere is polished rod.
Preferably, in above-mentioned a kind of stop valve, described upper seal support welds mutually with valve gap.
Preferably, in above-mentioned a kind of stop valve, between described valve gap and valve body, it is provided with pad.
Preferably, in above-mentioned a kind of stop valve, described valve body and valve seat are processed by cast steel.
The beneficial effects of the utility model are: the stop valve in this utility model is wear-resistant, good airproof performance, long service life, and valve body and valve seat process by cast steel, and therefore structural strength is higher.

Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail.The example of these preferred implementations has illustrated in the accompanying drawings.Shown in accompanying drawing and the embodiment of the present utility model that describes with reference to the accompanying drawings 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, a kind of stop valve, including: valve body 1, valve rod 2 and valve seat 3, described valve body 1 is processed by cast steel with valve seat 3, therefore has higher structural strength.One end of described valve body 1 is provided with import 4, and the other end of described valve body 1 is provided with outlet 5, and described valve seat 3 is arranged in valve body 1, and one end of described valve rod 2 extends vertically in valve body 1, and the epimere of described valve rod 2 is screw rod, and hypomere is polished rod.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 body 1 and valve gap 6, in the present embodiment, described fixture 8 is bolt and nut.One end of described valve rod 2 is provided with flap 9 and the valve clack cover 10 welded with flap 9 phase, it is provided with thrust pad 11 between described valve rod 2 and flap 9, being provided with upper seal support 12, spacer ring 13, filler 14 and gland 15 between described valve rod 2 and valve gap 6, described upper seal support 12 welds with valve gap 6 phase.Described gland 15 be arranged over pressing plate 16, it is connected by eyelet bolt 17 and nut 18 between described pressing plate 16 and valve gap 6, it is connected by bearing pin 19 between described eyelet bolt 17 and valve gap 6, the valve stem nut 20 being arranged over matching with valve rod 2 of described pressing plate 16, described valve stem nut 20 be arranged over handwheel 21, described handwheel 21 be arranged over plain cushion 22 and locking nut 23.The sealing surface weld deposit Si Taili hard alloy of described stop valve, thus substantially increasing the resistance to erosion of stop valve, decay resistance.
In this utility model, the operation principle of stop valve is: matched with valve stem nut 20 by the screw rod of valve rod 2 epimere, then rotation hand wheel 21, valve rod 2 can be made to make knee-action in valve body 1, when valve rod 2 moves downward, flap 9 seals with valve seat 3 phase, so that stop valve is in closure state, when valve rod 2 moves upward, flap 9 departs from valve seat 3, so that stop valve is in open mode.
In sum, the stop valve in this utility model is wear-resistant, good airproof performance, long service life, and valve body and valve seat process by cast steel, and therefore structural strength is higher.
