Description

Technical Field

[0001] The utility model relates to the technical field of liquid level gauges, in particular to a liquid level gauge for a mechanical seal auxiliary system. Background Art

[0002] The liquid level gauge for mechanical seal auxiliary system is usually used to monitor the liquid level of lubricating oil or coolant in the mechanical seal system. The liquid level gauge is usually installed on the liquid storage tank or oil tank of the sealing system to ensure the normal operation of the sealing system by detecting the height of the liquid level.

[0003] The welded glass plate level gauge uses a glass plate as the liquid level observation component. The level gauge is connected to the liquid storage device by welding. The existing level gauge is made of thick stainless steel plates, which is expensive and cannot be replaced as a modular component after being welded. The existing glass plate liquid level position indication is not obvious, and the observation angle is limited to the front of the level gauge. The parts of level gauges of different specifications are not universal, which increases costs.

[0004] Therefore, a liquid level meter for a mechanical seal auxiliary system is proposed. Utility Model Content

[0005] The purpose of the utility model is to solve the problems raised in the above background technology. The utility model provides a liquid level meter for a mechanical seal auxiliary system.

[0006] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

[0007] A liquid level gauge for a mechanical seal auxiliary system comprises two groups of liquid level gauge connectors, the surfaces of the connecting ends of the liquid level gauge connectors are respectively sleeved with a first O-ring, a second O-ring and a third O-ring, a glass tube is inserted into the end face of the liquid level gauge connector, a liquid level gauge protection tube is inserted into the end face of the liquid level gauge connector, and the liquid level gauge protection tube is sleeved on the outside of the glass tube, a liquid level indicating ball is arranged inside the glass tube, an external hexagonal flange face bolt is inserted into the inside of the liquid level gauge connector, and a gasket is sleeved on the surface of the external hexagonal flange face bolt, a hexagonal bushing is arranged at one end of the external hexagonal flange face bolt, and a hexagonal plug with an ED ring is inserted into the other end of the liquid level gauge connector.

[0008] Furthermore, the surface of the third O-ring and the inner wall of the glass tube are arranged in a close fit, and the end surface of the third O-ring and the surface of the second O-ring are arranged in a press fit.

[0009] Furthermore, the surface of the first O-ring and the inner wall of the liquid level gauge protection tube are arranged in a close fit.

[0010] Furthermore, the glass tube is made of high borosilicate glass material, and the first O-ring, the second O-ring and the third O-ring are all made of FKM or PTFE material.

[0011] Furthermore, observation slots are provided on both the front and rear inner walls of the liquid level gauge protection tube, and the liquid level gauge protection tube is made of stainless steel.

[0012] Furthermore, the liquid level indicating ball is movably arranged inside the glass tube, and when in use, the liquid level indicating ball floats on the top surface of the liquid in the glass tube.

[0013] The beneficial effects of the utility model are as follows:

[0014] The outer hexagonal flange bolt, the level gauge connector, the hexagonal bushing and the glass tube are connected and sealed by means of a gasket, a third O-ring and a hexagonal bushing. The outer hexagonal flange bolt is hollow with a hole inside, so that the inside of the level gauge is connected to the liquid storage device, so that the liquid level change can be reflected in the glass tube. The second O-ring acts as a buffer to separate the glass tube from the level gauge connector to prevent the glass tube from colliding with the level gauge connector and causing damage to the glass tube. The level gauge protection tube is fixed by the first O-ring. The level gauge protection tube is used for the glass tube. It can be replaced with other types of adapters through the hexagonal plug with ED ring. A pressure gauge and a pressure sensor can be installed. The connection and sealing with the liquid storage device are achieved with the help of the tapered thread of the hexagonal bushing and sealant. When working normally, the liquid level can be clearly observed through the level indicator ball.

[0015] Compared with the existing liquid level gauges, the assembly is simpler and more convenient. When the liquid level gauge is not needed, the threaded interface connecting the liquid storage device to the liquid level gauge can be sealed with a plug to realize the modular replacement of the liquid level gauge. The liquid level can be clearly observed through the liquid level indicator ball, and the parts are highly universal. It is only necessary to replace the liquid level gauge protection tube and the glass tube to realize the assembly of liquid level observation devices of different specifications.

More specifically, the outer hexagonal flange bolt 6, the level gauge connector 1, the hexagonal bushing 10 are connected and sealed by the gasket 5, the third O-ring 9 and the hexagonal bushing 10. The outer hexagonal flange bolt 6 is hollow with a hole inside, so that the inside of the level gauge is connected to the liquid storage device, so that the liquid level change can be reflected in the glass tube 2.
