[0031] Glass tube, it is vertically installed on the side of tank;
[0032] Coke valve, lower flange mouth is installed on the bottom outer wall of tank, the coke valve is installed on the lower flange mouth of tank, the lower end of glass tube is installed on coke valve, so that the fluid in tank sequentially enters into glass tube through lower flange mouth and coke valve;
[0033] Elbow type glass tube connector and hose, upper flange mouth is installed on the top of tank, one end of elbow type glass tube connector is connected with the upper end of glass tube, the other end is connected with one end of hose, the other end of hose is connected with upper flange mouth;
[0034] The hose is transparent hose, so as to facilitate the observation of liquid level;
[0035] The upper flange mouth is located on the top surface of tank, the upper flange mouth is arranged on the top of tank, so that the liquid level meter can display the liquid level condition of the top of tank, which significantly improves the effective distance of liquid level display, and provides more intuitive and accurate liquid level information for user, and through the real-time display of top liquid level, user can judge the liquid level state in tank in time, effectively avoids the full tank overflow problem caused by the failure to observe the top liquid level of tank, so as to ensure the production safety and reduce resource waste;
[0036] The short tube flange is bolted on the upper flange mouth, and the end of the hose is connected with the short tube flange;
[0037] A plurality of groups of lifting pipe clamps, one end is connected with the tank, and the other end is clamped on the outer circumferential surface of glass tube, so as to clamp the glass tube, the lifting pipe clamp is a clamp;
[0038] U-shaped piece, baffle, connecting column, connecting bolt, connecting nut, fixing nut and sleeve are sequentially connected between each group of lifting pipe clamps and tank;
[0039] One end of the U-shaped piece is fixed on the outer circumferential surface of the lifting pipe clamp, and the other end has a through hole for the connecting column to extend into, the through hole is a circular hole, and the U-shaped piece is formed into a generally U-shaped structure;
[0040] One end of the connecting column extends into the U-shaped piece, and the connecting column is formed into a generally cylindrical structure;
[0041] The baffle is fixed on the end face of one end of the connecting column extending into the U-shaped piece;
[0042] One end of the connecting bolt is connected with the end face of one end of the connecting column extending out of the U-shaped piece, and the connecting nut is screwed on the connecting bolt.
[0043] The end face of the fixed nut is welded and fixed on the end face of the sleeve, and both are arranged concentrically, and the other end face of the sleeve is welded and fixed on the outer wall of the tank body;
[0044] The lifting tube clamp opposite to the glass tube and the sleeve opposite to the tank body are fixed as a whole by the connecting bolt;
[0045] When the connecting bolt is screwed, the lifting tube clamp does not rotate with the rotation of the connecting bolt because the connecting column rotates on the U-shaped piece, and when the connecting bolt rotates, the length of the connecting bolt inserted into the sleeve changes, thereby adjusting the distance between the lifting tube clamp and the side wall of the tank body;
[0046] In order to avoid unnecessary breakage of the glass tube during installation, a rubber pad (not shown in the figure) is arranged between the lifting tube clamp and the glass tube to prevent the glass tube from being crushed.
[0047] The use principle of the external liquid level meter for facilitating observation of the liquid level of the tank body is as follows:
[0048] During installation, the lower flange 7 and the upper flange 8 are first welded on the tank body, then the cock valve 1 is installed on the lower flange 7, and then the lifting tube clamp 3 is clamped on the glass tube 4, but not tightly clamped at this time. At this time, the connecting bolt 13 is screwed, and the lifting tube clamp 3 does not rotate with the rotation of the connecting bolt 13 because the connecting column 11 rotates on the U-shaped piece 10. When the connecting bolt 13 rotates, the length of the connecting bolt 13 inserted into the sleeve 16 changes, thereby adjusting the overall length of the lifting tube clamp 3. After the length is adjusted to a suitable length, the sleeve 16 is welded on the outer wall of the tank body 2. After welding, the connecting nut 14 is tightened, thereby fixing the length of the lifting tube clamp 3. Then the lifting tube clamp 3 is tightly clamped. According to the use requirement, a layer of rubber pad (not shown in the figure) can be placed between the lifting tube clamp 3 and the glass tube 4 to prevent the glass tube 4 from being damaged. In addition, the number of the lifting tube clamp 3 is determined according to the requirement. The elbow type glass tube connector 5 is connected to the top end of the glass tube 4, the short tube flange 9 is bolted on the upper flange 8, and the hose 6 is clamped to complete the installation.
[0049] Because the distance between the lifting tube clamp 3 and the tank body 2 is adjustable, even if there is deviation in the welding process of the lower flange 7, the lifting tube clamp 3 can be adjusted. The top end of the glass tube 4 is connected to the tank body 2 through the hose 6, so even if there is deviation in the welding of the upper flange 8, the flexibility of the hose 6 can compensate for it. Although the hose 6 can be used instead of the glass tube 4, the hose 6 needs to be transparent. The current transparent hose 6 will discolor after a long time of use, which makes it difficult to see the liquid level in the tube. Although the glass tube 4 is brittle, it has high transparency and will not discolor after a long time of use, which is convenient for observing the liquid level.
[0050] Compared with setting the upper flange 8 on the side wall of the tank body 2, setting the upper flange 8 on the top of the tank body 2 has a long effective distance of liquid level display, can display the liquid level on the top of the tank body 2, and prevents overflow caused by continuing to inject liquid after the tank is full due to the inability to observe the liquid level on the top of the tank body 2.
