Abstract
The utility model relates to an internally closed type emergency valve used during an abnormal situation of liquid drain valves of a vehicle-mounted storage tank. The storage tank is provided with the liquid drain valves; a liquid inlet pipe is arranged in the storage tank; one end of the liquid inlet pipe is communicated with an outflow opening of the tank wall, and a liquid inlet is formed in the other end of the liquid inlet pipe; a liquid inlet closing piece corresponds to the liquid inlet and is fixed at the lower part of a valve rod; a screwing part is arranged at the other end, extending out of the tank wall, of the valve rod; sealing parts are arranged on the valve rod and the extending opening of the valve rod. The internally closed type emergency valve has the benefits that liquid can be safely prevented from flowing out when the liquid drain valves of the vehicle-mounted storage tank are in an emergency, and liquid drain valves can be conveniently maintained and replaced; a valve sleeve is in threaded connection with the valve rod so as to be unlikely to be disengaged from the valve rod during use, so that the emergency valve can be conveniently operated by an operator; the structure is simple; all the liquid drain valves can be controlled by one valve.

Background technique
At present, in wet-process metallurgy industry, the tapping valve of vehicle-mounted storage tank, is usually located at tank body lower part both sides, with the making of corrosion-proof type material, but all has certain defect.First in the time that valve damages, valve occurs being not closed completely or cannot open, valve loses effective control, run into urgency, for example, when tank body seepage, can not emit in time solution and cause the damage of installations and facilities and material can not reclaim in time the waste causing, therefore design and that standby valve device is installed is particularly important.
Model utility content
The purpose of this utility model is to overcome the deficiency of above-mentioned prior art, provide not only corrosion-resistant but also wear-resisting, the life-span long, lightweight and easy to use a kind of vehicle-mounted storage tank tapping valve when abnormal in enclosed emergency valve.
The utility model object is achieved through the following technical solutions: enclosed emergency valve in when a kind of vehicle-mounted storage tank tapping valve is abnormal, this storage tank is provided with discharge valve, liquid inlet pipe is set in storage tank, described liquid inlet pipe one end is communicated with the outflow opening of tank skin, the other end arranges liquid entering hole, be provided with liquid entering hole closure member corresponding to liquid entering hole, and liquid entering hole closure member is fixed on stem lower portion, the other end that valve rod stretches out tank skin is provided with and screws parts, and valve rod and valve rod extending port place are provided with sealed member.
Described liquid entering hole closure member is cone, and liquid entering hole correspondence is the rounding conical surface.
The surface of contact of described liquid entering hole and liquid entering hole closure member is provided with seal ring.
Described sealed member comprises valve body, filler, gland, and valve body is fixed on the outer flange arranging of outlet, in valve body, is cavity, and valve rod runs through valve body, and filler seals the surface of contact of valve body and valve rod compressed by gland, and gland is fixed on valve body by clamping bolt.
The described parts that screw comprise valve pocket, handwheel, and valve pocket is movable up and down to be arranged on valve body, and valve pocket is connected with threaded stem, and the part that valve pocket is positioned at cavity is provided with and stops projection, and handwheel is connected with valve pocket key and to pass through locking nut fastening.
If when discharge valve has more than two, can be communicated with one of them outflow opening by liquid inlet pipe, then on liquid inlet pipe, offer arm, be communicated with other discharge valves by arm.While only having two discharge valves, be communicated with two outflow openings by a liquid inlet pipe, on liquid inlet pipe, offer a liquid entering hole.
The utility model beneficial effect: make the in case of emergency prevention liquid outflow of safety of vehicle-mounted storage tank tapping valve, facilitate the maintain and replace of tapping valve; Valve pocket adopts with valve rod the mode being threaded, difficult drop-off in using process, easy-to-operat personnel operation; Structure is simplified, and a valve can be controlled all discharge valves.
