The details of the use of autoclave

An autoclave is a large, heavy, heavy pressure vessel. The use of autoclave is very extensive. It uses a large number of autoclaves for building materials such as coal ash bricks, microporous calcium silicate boards, heat-insulating asbestos boards, and high-strength gypsum. In the course of daily use, attention must be paid to details in order to ensure smooth work. Effectively.

1. The sealing ring used for sealing between the sealing ring kettle door and the kettle ring should always be inspected and replaced in time in order to ensure the effective sealing of the kettle door.

2. After the kettle kettle door product is put into the kettle, the kettle door should be closed carefully so that the kettle door and the kettle ring can be put in place, and the safety handle can be pulled down. After the final inspection of the kettle door closing condition before the air supply is completed to complete the maintenance, the kettle door is opened. Before you must check whether there is pressure in the kettle. First of all, open the safety handle so that the kettle door can be opened after the remaining gas in the kettle is exhausted. Note that the operator should avoid facing the kettle door to prevent it from being burned by high temperature air.

3. The safety valve is an auto unloading component when the autoclave is under high pressure. In order to ensure the good performance of the safety valve, it must be overhauled and routinely maintained.

4. Keeping the water flowing through the autoclave. In addition to the load caused by the internal pressure generated by the steam, the autoclave body must withstand the weight of the autoclave and the weight of the autoclave and products that are carried on the track fulcrum and the kettle support. Load, due to the condensate caused by the difference between the stability of the kettle top and the bottom of the tank, the autoclave under a long period of this cyclical stress, it is easy to make its constituent materials fatigue and lose part of the strength. At the same time, the corrosion of water and gas also tends to reduce the strength of the material.

Therefore, the condensate should be drained in time during use, especially in the initial stage of warming, a large amount of condensed water will be generated in the kettle. If it is not eliminated in time, it will gather at the bottom of the kettle to form a low-temperature area under the kettle to make the kettle body up and down. The temperature difference increases, resulting in excessively high stress difference and thermal deformation in the kettle.
