Abstract
The invention discloses a pneumatic wedge type gate valve. The pneumatic wedge type gate valve comprises a valve body, a valve cover and valve rod, wherein the valve cover is arranged on the top of the valve body; a gate plate is arranged at the lower end of the valve rod; a medium through hole is formed in the middle of the valve body; the gate plate is positioned in the medium through hole; a valve base is arranged between the medium through hole and the gate plate; the valve rod extends into the valve cover from the center of the valve body; the valve rod extending from the valve cover is connected with a converter mechanism; a gas cylinder is arranged at the upper end of the converter mechanism; a field indicator is arranged on the top of the gas cylinder; an edge-covered gasket is arranged between the valve cover and the valve body; the valve cover and the valve body are fixed and locked through a double-ended stud and a nut I; filler is arranged between the valve cover and the valve rod; a nut II is arranged between the valve rod and a filler pressure plate; a filler pressure sleeve is arranged between the filler pressure cover and the valve cover. The pneumatic wedge type gate valve disclosed by the invention is relatively reasonable in structure; the converter mechanism is arranged on the top of the valve cover, the gas cylinder is arranged on the top of the converter mechanism, and the gate plate is driven by the opening and closing of the gas cylinder, so that not only is the operation relatively simple and convenient, but also the conversion mechanism can be relatively convenient and beneficial for match.
Description
Technical field
The present invention relates to gate valve technical field, particularly relate to a kind of pneumatic Wedge gate valve.
Background technique
Gate valve uses a kind of valve comparatively widely in pipeline valve, for connecting or block the medium in pipeline.The open-shut device of gate valve is flashboard, configure by ram seal and can be divided into Wedge gate valve and parallel gate valve two class, wedge-type flashboard has single, double flashboard, and the moving direction of flashboard and flow direction perpendicular, gate valve is widely used in the fields such as oil, chemical industry, rock gas, power plant, iron and steel, colliery and sewage treatment.Existing Wedge gate valve great majority are electronic, and little for pneumatic type, and existing electric gate valve not only power consumption is larger, energy transition rate is very low, and the higher and sealability of user cost is poor etc., and the medium after well can not ensureing to open flashboard in pipeline in pipeline directly flows through, operate more complicated, and Wedge gate valve structure is more complicated, maintenance difficulty is large, and working life is also shorter.
Summary of the invention
For Wedge gate valve in the deficiencies in the prior art, the invention provides a kind of pneumatic Wedge gate valve.
To achieve these goals, the technical solution used in the present invention is:
A kind of pneumatic Wedge gate valve, comprise valve body, valve gap and valve rod, the top of described valve body is provided with valve gap, described valve rod lower end is provided with flashboard, medium through hole is provided with in the middle part of valve body, flashboard is arranged in medium through hole, valve seat is provided with between medium through hole and flashboard, valve rod stretches into valve gap from the center of valve body, the valve rod stretched into from valve gap is connected with switching mechanism, switching mechanism upper end is provided with cylinder, cylinder head is provided with on-the-spot indicator, bound edge pad is provided with between valve gap and valve body, by stud and nut one fixing and locking between valve gap and valve body, filler is provided with between valve gap and valve rod, nut two is provided with between valve rod and hold-down grid, filler pressing sleeve is provided with between Gland and valve gap.By adopting technical solution of the present invention, medium through hole along with the motion of cylinder band manual converting mechanism, from making valve rod move, finally can drive flashboard to carry out switch, thus making flashboard carry out closing and opening medium through hole.
Described nut two is two.
Be fixedly connected with by swing bolt between described Gland and filler pressing sleeve, by this setting, be connected with more fastening between Gland and valve gap.
Described cylinder is connected and fixed respectively by connecting bolt with on-the-spot indicator and switching mechanism, and by this setting, cylinder is connected more reliable with on-the-spot indicator and switching mechanism, mount and dismount convenient.
Beneficial effect of the present invention: compared with prior art, vibrational power flow of the present invention is more reasonable, valve gap top is provided with switching mechanism, switching mechanism top is provided with cylinder, the opening and closing of flashboard are driven by cylinder, not only operate more simple and convenient, and switching mechanism also can conveniently be conducive to coordinating; Valve body and valve gap, valve gap and Gland, Gland and switching mechanism, switching mechanism and cylinder, cylinder and on-the-spot indicator are all connected by being fixed between bolt or screw and nut, connect more fastening, also for convenience detach and installation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
