Description

Technical Field

[0001] The utility model relates to the technical field of mechanical seals, in particular to a feeding device with a feeding cover that prevents separation of a mechanical seal cooling system. Background Art

[0002] like Figure 1 As shown, a double-end sealing system is provided with a filling assembly 10 for adding a spacer fluid.

[0003] However, the current feeding hopper has the following problems: the material cover is separated from the hopper. When the isolation liquid needs to be added, the material cover needs to be removed and placed somewhere else. After the isolation liquid is added, the material cover is picked up and installed on the hopper, which makes it inconvenient to use; some install a rope on the cover plate, and the other end of the rope is installed on the hopper, but the rope cannot rotate with the material cover, which makes the rope easy to get tangled. Summary of the invention

[0004] In view of the deficiencies in the prior art, the utility model provides a feeding device with a feeding cover that prevents separation of a mechanical seal cooling system, so as to solve the problems mentioned in the above background technology.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0006] A feeding device with a feeding cover that prevents separation of a mechanical seal cooling system comprises a feeding pipe, a hopper threadedly connected to the feeding pipe, and a feeding cover threadedly connected to the hopper, wherein the inner wall of the hopper is provided with a convex block, a chain is fixed to the convex block, the inner wall of the feeding cover is provided with a circle of convex rings, the inner wall of the convex rings is provided with a circle of sliding grooves with a spherical cross-section, balls are slidably arranged in the sliding grooves, more than half of the balls are located in the sliding grooves, and the upper end of the chain is connected to the outer side of the balls.

[0007] Preferably, the material pipe includes a pipe body, a ball valve installed on the pipe body, and a mounting sleeve fixed to the top surface of the ball valve. The inner wall of the mounting sleeve is provided with an internal thread, and the lower end of the hopper is threadedly connected to the mounting sleeve.

[0008] Preferably, the inner wall of the material cover is provided with a first sealing ring.

[0009] Preferably, a circle of second sealing ring is provided on the inner wall of the mounting sleeve.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] The cover is threadedly mounted on the hopper and further connected by a chain. When the cover is removed, you can simply let go and the cover will not fall off due to the action of the chain. Moreover, when the cover is screwed, the ball will slide in the slide groove of the convex ring to drive the chain to rotate with the cover, thereby preventing the chain from getting tangled.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Example 1

[0020] See also Figure 2-5 A feeding device with a feeding cover that prevents separation of a mechanical seal cooling system comprises a feeding pipe 1, a hopper 2 threadedly connected to the feeding pipe, and a feeding cover 3 threadedly connected to the hopper. The feeding pipe 1 comprises a pipe body 101, a ball valve 102 installed on the pipe body, and a mounting sleeve 103 fixed to the top surface of the ball valve. The inner wall of the mounting sleeve 103 is provided with an internal thread, and the lower end of the hopper 2 is threadedly connected to the mounting sleeve 103. The hopper and the feeding pipe are detachably connected, which is convenient for replacement and installation.
