Referring to Figures 1 and 2, a tank container includes a tank 200 and a valve 100. The tank 200 is provided with an opening for loading and unloading materials. The valve 100 is fixed at the opening on the tank 200 to control the opening. opening and closing.

The valve member 100 includes a valve body 1 , a connecting bracket 12 and a valve core 3 . Among them, a connecting flange 13 is provided on the circumferential outer surface of the valve body 1 , and the connecting flange 13 is used for fixed connection with the tank body 200 . The inner wall surface of the first axial end of the valve body 1 forms a limiting convex ring 11. The second axial end of the valve body 1 is provided with a connecting bracket 12. The end of the connecting bracket 12 away from the valve body 1 protrudes from the valve. The second end surface of body 1. Among them, after the connecting flange 13 is connected to the tank 200, the connecting bracket 12 is located inside the tank 200, so that the height of the valve member 100 installed on the tank 200 is reduced.

Referring to Figures 2 and 4, the valve core includes a sliding rod 31, a sealing member 32 and an elastic member 33. The sliding rod 31 passes through the connecting bracket 12 and can move relative to the axis of the valve body 1. The sealing member 32 is connected to the sliding rod 31 and is located on the convex side facing away from the connecting bracket 12 . The elastic member 33 is elastically connected between the sealing member 32 and the connecting bracket 12 to drive the sealing member 32 and the limiting convex ring 11 Abut.

That is to say, the sliding rod 31, the sealing member 32 and the elastic member 33 form the valve core 3 of the valve member 100. When the sealing member 32 abuts against the limiting convex ring 11, the valve member 100 is closed. When the valve core 3 needs to be opened, the sealing member 32 is pushed in the direction of the compressed elastic member 33 so that the sealing member 32 is separated from the limiting flange 11 , and a channel for materials to pass is formed between the limiting flange 11 and the sealing member 32 . When the force pushing the sealing member 32 to move disappears, under the elastic force of the elastic member 33 , the sealing member 32 returns to the contact state with the limiting convex ring 11 , thereby realizing the automatic closing of the valve member 100 .

In detail, the elastic member 33 is sleeved on the sliding rod 31, and one end of the elastic member 33 is in contact with the connecting bracket 12, and the other end is in contact with the sealing member 32. The elastic member 33 is in a compressed state, so that when the elastic member 33 Under the action of elastic force, there is pressure between the seal 32 and the limiting convex ring 11 to prevent the valve core 3 from opening.

Among the above, the elastic member 33 is preferably one or more of a compression spring and a disc spring. In order to reduce the resistance when the material passes through the valve member and increase the contact area, the surface where the seal 32 contacts the limiting convex ring 11 is configured as a tapered surface or an arc surface.

Referring to Figure 4, in this embodiment, when the pipeline used for loading and unloading materials in the tank 200 is connected to the valve body 1, a pipeline joint 400 adapted to the valve 100 is provided on the pipeline, and the pipeline joint 400 is fixed on the valve body. After the first end of 1 is on, the push plate 410 inside the pipe joint 400 can push against the seal 32 and push the seal 32 to a position where it does not contact with the limiting flange 11, so that the seal 32 is in contact with the limiting ring 11. There is a space for materials to pass between the raised rings 11 to realize communication between the tank 200 and the pipeline.

Referring to Figures 1 and 4, when the valve member 100 is installed on the tank 200, the second end of the valve body 1 is connected to the tank 200, that is, the one end of the valve body 1 provided with the connecting bracket 12 is connected to the tank 200. Among them, the middle part of the connecting bracket 12 protrudes along the side facing away from the limiting convex ring 11. After the valve body 1 is connected to the tank 200, the connecting bracket 12 extends into the inside of the tank 200. Therefore, the sliding rod 31 and the sealing member are ensured. 32 and the elastic member 33 require active space, the height of the valve body 1 can be reduced. That is to say, when the valve member 100 is fixed on the tank body 200, the height of the valve member 100 outside the tank body 200 is smaller, so that the height of the valve member 100 after installation is reduced and the space occupied by the tank container is reduced.

In some embodiments, an overflow box 300 is installed on the top of the tank 200 , and the valve 100 needs to be installed in the overflow box 300 so that the overflow box 300 protects the valve 100 , that is, when rainwater exists, The overflow box 300 blocks rainwater on the outside of the valve body 1 to prevent rainwater from corroding the valve member 100 . Due to certain height restrictions of the overflow box 300, this application lowers the installation height of the valve member 100 by protruding the middle part of the connecting bracket 12 along the side facing away from the limiting convex ring 11, so that the valve member 100 can be fully Contained in the overflow box 300.

Referring to Figures 3 and 4, the connecting bracket 12 includes a connecting platform 121 and a connecting arm 122. The connecting platform 121 is located outside the second end of the valve body 1.

The circumferential outer wall of the sliding rod 31 is in contact with the inner wall surface of the through hole for passing the sliding rod on the connecting platform 121, so that the connecting platform 121 plays a guiding role for the sliding rod 31, thereby improving the distance between the seal 32 and the limiter. Sealing after contact between raised rings.

The outer diameter of the connecting platform 121 is smaller than the inner diameter of the valve body 1. The connecting arm 122 is tilted from the valve body 1 to the connecting platform 121. The connecting arm 122 is arranged at an angle along the axis of the valve body 1. That is to say, the connecting bracket 12 is in the form of a boss. shape, one end of the connecting bracket 12 connected to the valve body 1 has a large diameter and the other end has a small diameter, making it convenient to install a siphon connected to the valve body 1 inside the tank 200, and the siphon extends from the valve body 1 to the tank 200 bottom, so that when discharging materials, the siphon can suck out the materials at the bottom of the tank 200 .

The outer diameter of the connecting platform 121 is smaller than the inner diameter of the valve body 1 , and the connecting arm 122 is tilted from the valve body 1 to the connecting platform 121 , so that the connecting arm 122 plays a guiding role in guiding the siphon tube when installing the siphon tube. Moreover, there is a large space for materials to pass between the inner wall of the siphon tube and the connecting platform 121 .

One end of the connecting arm 122 away from the connecting platform 121 is connected to the inner wall surface of the valve body 1, and the connecting flange 13 is provided at the second end of the valve body 1, so that the structural diameter of the valve body 1 is smaller at the connecting flange 13 away from the first end. Small, thereby making it convenient for the connecting bracket 12 to extend into the inside of the tank 200.
