Ultra-high-pressure anti-explosion structure with transition joint

Abstract

The invention relates to the field of manufacturing of hydraulic devices, in particular to an ultra-high-pressure anti-explosion structure with a transition joint. The ultra-high-pressure anti-explosion structure comprises the transition joint, wherein ends of two sides of the transition joint are respectively set as an upper end and a lower end; the upper end is communicated with an upper hydraulic element fixedly; the lower end is communicated with a lower hydraulic element fixedly; high-pressure fluid is fed in the upper element and flows into the lower hydraulic element through the transition joint; the lower end of the transition joint is in threaded connection with the lower hydraulic element fixedly; an O-shaped ring for sealing a connector is mounted between the end part of the lower end and the end part, with threads, of the lower hydraulic element; an ultra-high-pressure anti-explosion opening is formed in the side wall of the transition joint and is positioned at a corresponding position of the outer side of the O-shaped ring; the ultra-high-pressure anti-explosion opening is communicated with an external environment; the inner diameter of the ultra-high-pressure anti-explosion opening is smaller than the thickness of the O-shaped ring.

Description

technical field [0001] The invention relates to the field of hydraulic device manufacturing, in particular to an ultra-high pressure explosion-proof structure of a transition joint. Background technique [0002] Hydraulic equipment is a mechanical device with a wide range of applications and is widely used in various industries. However, during the actual use of existing hydraulic equipment, problems often occur at the sealing joints that go downstairs and burst, resulting in Large-scale environmental pollution, equipment damage, and even personal injury and other safety hazards. [0003] Among them, the transition joint is a common sealing connection device in the field of hydraulic cylinders. It is often used in conjunction with devices such as copper gaskets or O-rings.

[0002] Hydraulic equipment is a mechanical device with a wide range of applications and is widely used in various industries. However, during the actual use of existing hydraulic equipment, problems often occur at the sealing joints that go downstairs and burst, resulting in Large-scale environmental pollution, equipment damage, and even personal injury and other safety hazards

[0003] Among them, the transition joint is a common sealing connection device in the field of hydraulic cylinders. It is often used in conjunction with devices such as copper gaskets or O-rings. However, when the fluid pressure is too high or due to other reasons, the copper gasket or O-ring When a leak occurs, the high-pressure fluid fails to leak in time, resulting in a situation where the local back pressure is close to or equal to the original system pressure, which greatly increases the shear force on the thread at the hydraulic component and the transition joint, thereby reducing the safety factor of the thread and increasing danger of the location

[0004] If the leakage of the above-mentioned high-pressure fluid is not detected in time, the high-pressure fluid will be discharged from the root of the thread of the hydraulic component. Since the flow direction of the high-pressure fluid is unpredictable, once it overflows, it will cause huge pollution, and in severe cases, it may even cause personal injury to nearby personnel. casualties
