Description

The utility model relates to the equipment of railway tank cars, namely, to the gates of drain devices and can be installed on commercially available universal drain devices of tank cars as the first additional shutter, which serves to ensure the safety of cargo (oil products) during loading and unloading operations and transportation.

The prior art known shutter drain device of the tank car, comprising a housing with inlet and outlet nozzles, a lid covering the hole in the side wall of the housing, and a locking member in the form of a rotary plate with a saddle, inclined mounted in the inlet nozzle, and a forced closing-opening mechanism comprising a rod with an end extending through the lid under a removable handle (see patent RU92503, class F16K 1/22, publ. March 20, 2010). The main disadvantage of the known device is the inconvenience of use, due to the large stroke of the rod outside the housing when opening the shutter, which is extremely inconvenient in conditions of limited space under the tank.

The technical problem is the creation of a reliable and easy-to-use shutter, which can be installed as part of mass-produced equipment and provides the possibility of introducing mechanized and automated devices through it during routine maintenance (washing, steaming, degassing). The technical result consists in increasing the compactness of the device. The problem posed is solved, and the technical result is achieved by the fact that in the gate of the drainage device of the tank car containing a body with inlet and outlet nozzles, a lid covering the hole in the side wall of the hull, and a locking member in the form of a swivel plate with a saddle mounted obliquely in the inlet the nozzle, and a forced closing-opening mechanism comprising a rod with an end extending through the lid under the removable handle, the rod is installed in the lid with the possibility of free rotation, and on the opposite from the handle to The end is equipped with a thread along which a slider nut moves, mounted in the slots of the lever fixed on an axis inside the housing and connected to the plate. The plate is preferably connected to the lever by means of a swivel mount. The shutter is preferably provided with a position indicator of a forced closing-opening mechanism located outside the housing. The outlet pipe is preferably provided with a shell around the entire perimeter.

The drawing shows the proposed shutter in the closed (solid lines) and open (dash-dotted lines) position.

The proposed shutter drain device of the tank car is a housing 1 with inlet 2 and outlet 3 nozzles, equipped with a lid 4, covering the hole in its side wall. Inside the housing 1 there is a locking element in the form of a rotatable movable plate 5 with a saddle 6, inclined mounted in the inlet pipe 2, and a forced closing-opening mechanism. In the open position, the plate 5 is pressed against the base of the lid 4 and does not reduce the passage section between the inlet 2 and outlet 3 nozzles.

The forced closing-opening mechanism consists of a rod 7 mounted in the cover 4 with the possibility of free rotation, a lever 8 and a slider nut 9 installed in its grooves. One end of the rod

7 through seals 10, ensuring the tightness of the working cavity of the housing 1, leaves through the cover 4 and is equipped with a spindle 11 for a removable handle, and the other is provided with a thread along which the slider nut 9 moves. The lever 8 is mounted on the axis 12 inside the housing 1 and by means of an axial hinge the fasteners 13 are connected to the plate 5. The plate 5 is equipped with a rubber sealing ring 14, fixed with a fixing ring 15 and bolts 16.

For visual indication of the position of the forced closing-opening mechanism outside the housing 1, a pointer 17 is installed with markings in the form of letters and the letters “O” and “3” and a fixing screw 18.

The outlet pipe 3 around the entire perimeter is equipped with a shell 19, providing complete tightness of the shutter.

The proposed shutter works as follows.

When the spindle 11 is rotated using the handle (not shown in the drawings) counterclockwise, the slider nut 9 is screwed onto the rod 7. In this case, using the slider nut 9 connected in series, the lever slots 8 force the lever to turn

8 on the axis 12, which, in turn, through the mount 13 pulls the plate 5, thereby opening the passage of the shutter.

When the spindle 11 is rotated clockwise, the slide nut 9 is unscrewed from the rod 7 and, through the interaction of the above parts and elements, the shutter closes.

Due to the execution of the rod stationary in the axial direction, the proposed valve in any position does not change its most compact overall dimensions, which greatly simplifies its use. At the same time, its design preserves the working diameter of the drain hole 200 mm, which allows the tank car to be drained with a shutter installed within the regulated time standards for the tank car with a universal drain device, and also provides the possibility of introducing mechanized and automated devices through it during routine maintenance (washing, steaming, degassing), i.e. provides the ability to carry out all maintenance work without dismantling the shutter.

The proposed valve has passed a set of tests, including bench tests, impact strength tests and hydraulic tests. The shutter is applicable to all lower discharge devices used in Russia and the Commonwealth countries.
