An anti-drip suction tube connection joint

Abstract

Disclosed is an anti-drip suction tube connector, comprising a connector body (1), a fixed end (2), a 90-degree interface end (3), an elastic seal body (4), a valve element (5) and a spring (6). The connector body is fixedly connected to the fixed end in a sealing manner. The 90-degree interface end is rotatably connected to the fixed end in a sealing manner. Guide slots (2-1) are arranged at a lower end of the fixed end. The valve element comprises a plunger (5-1) and the same number of guide winged edges (5-2) as there are guide slots. The guide winged edges of the valve element are in sliding fit with the guide slots. One end of the spring abuts against the fixed end, and the other end of the spring abuts against spring catch slots (5-3) on the guide winged edges. The elastic sealing body comprises a ring-shaped body (4-1). A lower end of the ring-shaped body is provided with a tapered ring (4-2) extending upwardly. The tapered ring is provided with a fluid through hole (4-3). A lower end of the elastic sealing body abuts against a step (1-1) in the body. A wing-shaped liquid accommodating slot (4-4) is formed between the ring-shaped body on the elastic sealing body and the tapered ring. The plunger abuts against the fluid through hole of the elastic sealing body in a sealing manner by means of the spring. The connector can be automatically opened when it is in place by means of its own structure, and can be automatically closed after being disengaged from an operating system, so that residual liquid in an operating pipeline can be effectively prevented from dripping out after being disengaged from the operating system, thereby improving the safety of the system.

Description

technical field [0001] The invention relates to the technical field of suction tube connection joint equipment, in particular to a drip-proof suction tube connection joint. Background technique [0002] Suction tube connectors are widely used in daily life and industrial production. It can be said that they are ubiquitous. Traditional suction tube connectors generally adopt an in-line structure, and the in-line structure is fixed by interference fit. However, if the interference If the interference is too large, it will easily cause installation difficulties, and if the interference is too small, it will cause unreliable fixation. Especially when changing the suction pipe connection joint, the water in the pipe will cause great trouble to the installation. The two ends of the suction pipe connection joint The joints are always open. When the joints are pulled out after work, the residual liquid in the conduit will easily leak and cause inconvenience; the joints fixed on the ...
