Compared with the prior art, the pipe joint has the advantages that: the diameter of a joint part of a pneumatic pipeline for light powders cannot change suddenly, the powders can be prevented from being accumulated, and the powders can be smoothly transported.
Description
Technical field
The utility model relates to a kind of joint that conveyance conduit connects usefulness that is used for.
Background technique
Use strength to obtain to use by the line transportation light powder.Light powder moves with the gas that flows in pipeline, and mobile phase is seemingly in pipeline for situation and fluid.The place but pipe shape changes, mobile powder may produce accumulation and influence transfer efficiency, may blocking pipe when serious.Therefore, directly use existing gas pipeline joint, liquid pipe joint effect all undesirable.The air-flow of light powder and liquid, gas property are different, for the physical and chemical performance of inner-walls of duct material specific (special) requirements are arranged.Two mouths of pipe that pipe coupling connected all have difference at aspects such as direction, position, calibers, need pipe coupling to have certain flexibility.
Summary of the invention
Goal of the invention of the present utility model is to provide a kind of Pneumatic conveying pipeline that is used for light powder to connect, unobstructed all the time double-deck pipe coupling in the time of can guaranteeing pipeline work.
The utility model is to realize like this, comprise first joint, the tail joint, be arranged on head and connect interior pipe and outer tube between the head and tail joint, first joint comprises the head end connection block, be socketed in the head end snap ring on the head end connection block, the head end snap ring comprises ring, be arranged on the internal projecting ring on the ring one end inwall, be arranged on the shackle member on the ring the other end inwall, the head end connection block comprises body, be arranged on the outer bulge loop on the body one end outer wall, the inner pipe joint of the body the other end is set, one end socket of interior pipe is fixed on the inner pipe joint, a wherein end socket of outer tube is fixed on the other end of body, the tail joint comprises the end connector seat, be socketed in the tail end snap ring on the end connector seat, the tail end snap ring comprises ring, be arranged on the internal projecting ring on the ring one end inwall, be arranged on the shackle member on the ring the other end inwall, the end connector seat comprises body, be arranged on the outer bulge loop on the body one end outer wall, the other end socket of outer tube is fixed on the other end of body of end connector seat, and interior pipe passes the body of end connector seat.During use; by shackle member the head end connection block of first joint is fixedlyed connected with the air-out of institute connecting pipe; by shackle member that the end connector seat of tail joint is fixedly connected with the air intake of another pipeline that is connected; under the protection of outer tube; even under the situation of bending; interior pipe also is not easy bending, with the interior conduit sealing, has guaranteed the smooth and easy of material transmission.
When guaranteeing outer canal curvature, have good crooked camber line, Guan Buhui bending in guaranteeing, outer tube is rubber pipe, metallic hose, metal bellows, rubber-like plastic tube.
Produce static in order to prevent to transmit material, inner tube material is textile cloth, pure silk, pure wool cloth.
Here, the shackle member on head end snap ring and the tail end snap ring is a pillar, so that corresponding with set L shaped groove on the air intake of the pipeline that is connected, the outer wall of connection on the exhaust outlet.
The beneficial effects of the utility model are that the diameter of the Pneumatic conveying pipeline connection place of light powder can not suddenly change, and can avoid powder to pile up, and guarantees that powder conveying is unobstructed.
