である。[Detailed Description of the Invention] The present invention relates to a bottom valve operating device for a tank truck for opening and closing a bottom valve provided at the bottom of the tank using a rotary handle provided at the top of the tank.

あつた。 Conventionally, in tank trucks, a bottom valve that can be opened and closed is provided at the discharge port that opens at the bottom of the tank, and a valve rod is provided that is screwed onto the top of the bottom valve to move the valve body up and down. A rotatably provided handle shaft and this valve stem were connected by a connecting rod via a universal joint. When the rotary handle is rotated, the valve stem rotates, and the valve body rises together with the valve stem to open the bottom valve.Generally, the handle shaft at the top of the tank is connected via a universal joint, and the bottom valve and axis center line are connected. Since they are provided in different positions, even if the valve stem rises, the connecting rod etc. may bend and the rotating handle may not rise, and the rising dimension of the valve stem and the rotating handle may not match. Therefore, it was not possible to judge the opening degree of the bottom valve based on the rising dimension of the rotary handle at the top of the tank.
In addition, since the handle shaft is raised via a connecting rod that is connected at an angle, bending loads are applied to the valve stem and handle shaft due to component forces, making it difficult to rotate the handle smoothly and making it difficult to operate the handle. It had the disadvantage of being heavy.

る。 In this invention, the valve stem is screwed to the upper part of the bottom valve, the handle shaft is screwed to the support part, and the handle shaft and the valve stem are connected by a connecting rod via a flexible joint.
A floating part that moves only in the axial direction is provided between the handle shaft and the valve stem, and only rotational motion is transmitted between the handle shaft and the valve stem, and axial movement is transmitted by the floating part. It is designed so that it does not work together,
The handle shaft and valve stem are raised and lowered by independently installed screws, so even if the valve stem and handle shaft are installed with different axes,
Since there is no bending load due to the diagonal connecting rod, the handle operation is smooth and easy.Also, the handle shaft is raised by an independent screw according to the amount of rotation of the rotating handle, so the rotating handle can be adjusted according to the amount of rotation. It is possible to provide a bottom valve operating device for a tank truck, which allows the bottom valve to be raised by the amount of rise and determines the opening degree of the bottom valve based on the amount of rise, making it easy to operate the bottom valve and preventing erroneous operation. be.

ツチに設けられている。 In FIG. 1, reference numeral 1 denotes a bottom valve fixed by bolts 7, 7 to a discharge port 5 opening at the bottom of a tank 3 of a tank lorry, and is constructed as follows. That is, 9 is a valve body that opens and closes a valve hole 13 that opens in the valve body 11. A valve stem 15 rotatably engages in the upper part of the valve body 11, and is secured by a screw 19 that engages with a groove 17 at the lower end of the valve stem 15. It is locked in the vertical direction.
The valve stem 15 is screwed into a support 21 fixed to the upper part of the valve body 11 through a threaded portion 23 . 25 is a discharge passage provided horizontally in the lower part of the valve body 11, and communicates with a discharge pipe (not shown). An emergency valve element 27 opens and closes a valve hole 29 provided in the discharge passage 25, and is pivotally connected to one end of the arm 31. The other end of the arm 31 is fixed to a shaft 33 so as to be swingable, and a lever 35 that is linked to an emergency lever (not shown) is fixed to the other end of the shaft 33. The upper end of the valve stem 15 is connected to the lower end of a connecting rod 39 via a universal joint 37. 40 is a wire mesh that covers the upper part of the bottom valve 1. Reference numeral 41 designates a floating portion provided in the middle of the connecting rod 39, which is locked in the rotational direction and freely movable only in the axial direction by a pin 45 that engages with a groove 43. 47 is a support part 49 provided at the upper part of the tank 3
A rotating handle 51 is fixed to the upper end of the handle shaft. Reference numeral 53 denotes a mounting seat welded to the upper part of the tank 3, to which a support portion 49 is fixed with bolts 55, 55. 57 is an oil seal, and 59 is a seal holder. Reference numeral 61 denotes a threaded cylinder that fits into the lower end of the support part 49 and is fixed by a screw 63, which is connected to the threaded part 6 provided on the handle shaft 47.
It is screwed together with 5. The lower end of the handle shaft 47 is connected to the upper end of the connecting rod 39 via a universal joint 67. The threaded portion 65 is provided at the same pitch as the threaded portion 23 of the valve stem 15.
