Background

In the fields of chemical industry, building, water supply, water heating, petroleum and the like, under the conditions of large vibration and frequent temperature change, the flexible pipe is required to be used for connection to play a compensation role, in the prior art, the compensation is realized by structures such as a corrugated pipe, a metal flexible pipe and a spring damper, but the corrugated pipe, the metal flexible pipe and the spring damper in the prior art have poor anti-explosion capability, and the application range of a single model product is small.

Disclosure of Invention

Aiming at the defects of the prior art, the invention provides a production process of an internal expanding type anti-explosion rubber joint with convenient processing, large deformation degree and strong anti-explosion capability, and the specific technical scheme is as follows:

a production process of an internal expanding type anti-explosion rubber joint comprises the following steps:

the method comprises the following steps: preparing a raw material rubber sheet;

step two: laying meridian lines and steel wires on the raw material rubber sheets;

step three: placing the spherical mold in a spherical mold;

step four: a heating device in the spherical mould heats the raw material rubber sheet, and simultaneously inflates an expansion air bladder in the spherical mould to expand the raw material rubber sheet;

step five: and (5) demolding after molding.

In order to better implement the invention, the method further comprises the following steps:

the first step is specifically as follows:

1.1, plasticating the natural rubber for 10-20 minutes;

1.2, adding damping rubber and mixing for 15-25 minutes;

1.3, adding an anti-aging agent and mixing for 5-10 minutes;

1.4, adding a vulcanizing agent and mixing for 3-7 minutes;

and 1.5, finishing the preparation of the raw material rubber sheet.

In the fourth step, the heating device in the spherical mold heats the raw material rubber sheet at the temperature of 160-180 ℃, and the heating time is 80-100 minutes.

The invention has the beneficial effects that: when the internal stress generated in the pipeline reaches the design value of the joint, the wall body of the joint can expand along with the pressure within 1 second, the bearable pressure of the joint can be 2-3 times of the design value, and the internal stress is passively absorbed and digested through the expansion of the wall body of the rubber joint, so that the pipeline is protected from being damaged, the noise generated by liquid flow is digested, and the noise reduction function is realized.

The whole process method is simple to operate, needs less equipment, is low in cost and facilitates popularization of the technology.
