Problems solved by technology

[0004] The flat pad pressure sealing gaskets used in the products currently on the market can only be used under low pressure conditions or in environments that do not require high leakage. For fluid transportation that requires large-diameter pipelines and requires no leakage When using other types of connectors, it can only increase the user's cost

Embodiment Construction

[0018] The specific embodiments of the present invention will be described in detail below based on the drawings.

[0019] according to Figure 1 to Figure 5 As shown, the large-diameter cam-locking quick coupling described in this embodiment includes a male connector 1, a female connector 3, and a pressure sealing gasket arranged between the male connector and the female connector. 2. The opposite end faces of the male connector and the female connector are provided with annular grooves 11 for connecting pressure sealing gaskets, and each groove is connected with a pressure sealing gasket 2, the male connector and The two pressure sealing gaskets on the end face of the female connector are pressed against each other to seal the quick joint. Four cam lock handles are installed on the outer circumference of the female connector to connect with the male connector.

[0020] The pressure sealing washer is integrally formed of rubber, and the structure includes a clamping part 22 that...

Abstract

The invention discloses a large-diameter cam locking type rapid connector. The large-diameter cam locking type rapid connector comprises a female connector, a male connector and pressure sealing gaskets, wherein the female connector and the male connector are matched with each other; the pressure sealing gaskets are arranged between the male connector and the female connector; corresponding end faces of the male connector and the female connector are provided with annular clamping grooves for connecting the pressure sealing gaskets; each clamping groove is internally connected with one pressure sealing gasket. Each pressure sealing gasket comprises a clamping part and an abutting part; the outer end of each abutting part is an inclined abutting face; each abutting face has high inside and low outside and the inner end of each abutting face extends inwards to form an inner convex part; the inner wall face of each inner convex part is a convex arc-shaped surface; when high-pressure fluid in a pipeline passes through the position of the rapid connector, the pressure is generated on the convex arc-shaped surface positions of the pressure sealing gaskets by the high-pressure fluid so that the pressure between the two pressure sealing gaskets is increased and the abutting surface between the two pressure sealing gaskets does not leak.

Description

Technical field [0001] The invention belongs to the field of quick joint structure for fluid conveying pipelines, and particularly relates to the structure of a large-diameter cam locking type quick joint. Background technique [0002] The cam lock type quick connector is derived from the US military AA-59326 standard and the European Union EN14420-7 standard, and is used for the connection of fluid conveying pipelines. Because of its fast and convenient disassembly and assembly, it has been widely used in the field of fluid transportation. The cam lock type quick connector is composed of a female body, a male body, a cam lock handle assembly and a seal. In my country, standards for the use of similar products have also been formulated, such as "Ship Injection Head Connector GJB1122-91" and "Hose Quick Connector GB / T 16693-1996". As the amount of fluid transportation is increasing and the efficiency requirements are higher, the use of large-diameter pipelines is increasing, and...
