This invention relates to vehicles for the transport of special goods.

The purpose of the invention is to reduce spatter when draining corrosive liquid and simplify the construction of the tank truck.

Equipping the tanker truck with a drain suction device consisting of a hollow body with openings and blockage valve-mounted valves connected to the suction line of the ejector and U-shaped meters with a drain pipe in conjunction with a drain perforated glass, reduces the splashing of corrosive liquid during draining and simplifying the design due to the absence of a transfer pump and its drive.

The drawing shows a tank truck, a general view.

The tank truck for aggressive liquids contains a tank 1 from the upper filling port through which the drain pipe 2, made in the form of an 11-shaped pipe), the ejector 3 with the suction line 4, having a source of discharge, the drain suction device 5, consists The main part of the hollow body 6 located under the container 1 with openings in its upper and lower walls. In the hollow case 6, the upper 7 and lower 8 stop valves, spring-loaded respectively with springs 9 and 10, are installed to block the openings. The upper shut-off valve 7 is rigidly connected to the float II by means of a rod 12. On the bottom side of the first case 6 The valve 8 is fitted with a perforated bowl 13. The cavity of the housing 6 is connected to one of the ends of the G1-shaped drain connection 2 and to the suction inlet 4 of the ejector 3.

Tank truck fu) 1kkioniruet as follows.

For cjmBa aggressive fluid from the tank 1 include the ejector 3, which creates a vacuum in the intake. Magister: and 4 by blowing exhaust gases of the car through the ejector 3. At the initial moment K; iaiiaHbi 7 and 8 block the holes in the upper and lower walls of the hollow body 6 Due to the creation of a vacuum in the cavity of the housing 6 (; the agresscBBoii fluid is sucked from the tank 1 through the drain pipe 2. As the cavity of the housing 6 is filled with liquid, the float 11 pops up and the valve 7 opens, closing the hole in the upper wall to 6. At the same time, under the action of the liquid column in the housing 6, the valve 8 opens, blocking the hole in the bottom wall of the housing 6. Air passing through the hole in the upper wall of the corus 6 is sucked into the main 4 of the ejector 3, preventing it from entering aggressive liquid. The liquid is drained from the housing 6 through the hole in the bottom wall and the perforated cup 13 into the stationary

5 storage. Simultaneously with the start of draining the liquid from the cup 13, the need for the ejector to work is eliminated and it can be turned off, since the liquid is drained by gravity due to the fact that the housing 6 is located under the tank 1.

The presence of springs 9 and 10 makes it possible to torment the force of opening of valves 7 and 8 to the required force. Filling capacity 1 is achieved by any known path through the upper casting neck.
