Description

Screw thread formula relief vent condenser pipe

Technical Field

The utility model relates to the technical field of glass instruments and chemical glass condensing equipment, in particular to a threaded air vent condensing pipe.

Background

The condensing tube is experimental equipment capable of condensing, recycling and reusing volatile solvents in the reactor. Currently, there are reflux condenser, straight condenser, air condenser, spherical condenser, etc.

The charging/discharging function structure of the existing condenser tube is to achieve the sealing purpose by matching a tapered grinding opening and a grinding plug, and the discharging function is achieved by utilizing the position relation of the relevant holes on the circumference of the grinding opening and the grinding plug. The grinding mouth is positioned on the condensing pipe, and the grinding plug is also called a charging pipe or a deflation piston. The connection with grinding and grinding has the following disadvantages:

1. because the taper processing of the grinding mouth and the grinding plug inevitably has errors, the effect of complete sealing between the grinding mouth and the grinding plug cannot be achieved.

2. In order to achieve the sealing effect of the grinding mouth and the grinding plug, vacuum grease needs to be coated on the sealing surface, but when chemical materials with high purity requirements are treated, the vacuum grease can be influenced, so that the vacuum grease cannot be allowed.

3. If the vacuum grease is not coated, the volatile solvent enters the contact surface of the grinding mouth and the grinding plug, and is extremely easy to cause 'seizure' between the grinding mouth and the grinding plug after condensation; however, after application of the vacuum grease, the vacuum grease will change over time due to the use of the instrument at high temperatures, and can also cause "seizure" of the burr and the burr plug.

4. Once the phenomenon of seizure appears between the grinding plug and the grinding mouth, if the grinding plug and the grinding mouth are very difficult to separate, the feeding pipe is often broken, and even the expensive condensing pipe is broken and scrapped.
