Abstract
The invention discloses a dual-fluid channel rotary joint. The dual-fluid channel rotary joint comprises a rotating part 1, a fixing part 2, a baffle ring 4 and a plug, wherein the rotating part 1 and the fixing part 2 are in dynamic seal matching. The dual-fluid channel rotary joint is characterized in that: a dynamic fluid guide channel A and a dynamic fluid guide channel B are reserved on the rotating part 1; the dynamic fluid guide channel A and the dynamic fluid guide channel B are respectively communicated with a dynamic side channel A1 and a dynamic side channel B1 which are arranged radially through communicating channels which are axially arranged independently in parallel; the dynamic side channel A1 and the dynamic side channel B1 are respectively communicated with a static fluid guide channel A2 and a static fluid guide channel B2 reserved on the fixing part 1; seal grooves are respectively reserved between the static fluid guide channel A2 and the static fluid guide channel B2 and outside the static fluid guide channel A2 and the static fluid guide channel B2; a block ring groove is reserved at the end of the rotating part 1; and a block ring 4 is arranged in the block ring groove and is limited and locked by using a clamp ring 5. In the dual-fluid channel rotary joint, the rotating part and the fixing part which are dynamic seal matching are adopted, so that the dual-channel independent fluid guide transmission medium is ensured and the fluid between the channels is prevented from cross-flowing without leakage in a rotation working condition. The dual-fluid channel rotary joint has a simple structure and works stably and reliably, and particularly can meet a process flow requirement of a waste film recovery machine.
Description
Technical field
The present invention relates to belong to dynamic water conservancy diversion utensil technical field, be specifically related to the rotating motion part-two-fluid passage swivel joint of a kind of Twin channel air feed, water, wet goods fluid.
Background technique
In the tobacco processing, clamping plate tobacco bale dress film recovery process is finished by useless film recovery machine, useless film reclaims machine and film is rotated wraps up in film and rotation and push away film and handle, dispose double-acting cylinder one in its rotary actuator and only reached cylinder control electric elements, gas circuit distribution member, control gas is infeeded by the single channel swivel joint, and control cylinder pushes away the film action.During production run, must be rotated power supply and single channel rotation air feed to rotary actuator cylinder control electric elements.Because electric control element is positioned in the rotating machinery, the outage that easily gets loose of cylinder control unit fixed position, the rate of fault height, remove and install cumbersome, safeguard consuming time seriously; Carbon brush, the conductive trough at rotation power supply position are easy to wear, and conductive trough is changed difficulty.For this reason, the improved procedure that adopts is to make it not need rotation with the power supply of the rotation in rotating machinery control unit is external, with cancellation rotation mode power supply control, but need rotating machinery to be set to double-acting cylinder, promptly need Twin channel rotation status supply gas, the two-fluid passage swivel joint that needs exploitation to satisfy the demand.The Twin channel rotation that the binary channel swivel joint of prior art has German FESST0 company to produce divides air parcel, and it can apply to the occasion of high speed rotating, but this Twin channel rotation divides air parcel complex structure, fabrication and processing required precision height, and need equipped high-speed bearing.This accessory of import exists lead time long, expensive problem.For this reason, the inventor is through experimental study, developed a kind of simple in structure, stable and reliable operation, two-fluid passage swivel joint, evidence, effect is good.
Summary of the invention
The object of the present invention is to provide a kind of simple in structurely, working stability is reliable, is suitable for supplying with the two-fluid passage swivel joint of water, gas, wet goods fluid.
The object of the present invention is achieved like this: comprise solid members, revolving part, baffle ring and plug, described revolving part cooperates with the solid members dynamic seal (packing), dynamic guide channel A and dynamic guide channel B are set on the described revolving part, both independently are provided with vertical connecting passage by parallel to an axis respectively and are communicated with dynamic side canal A1 and the dynamic side canal B1 that radially is provided with, dynamically side canal A1 and dynamically side canal B1 respectively with the static guide channel A2 that is arranged on the fixed block, static guide channel B2 is communicated with, and between described static guide channel A2 and the static guide channel B2 and the outside is provided with seal groove respectively; The revolving part end is provided with the baffle ring groove, assembles baffle ring in the described baffle ring groove, and uses the snap ring limitation locking.
Revolving part and fixed block that the present invention adopts dynamic seal (packing) to cooperate cooperate, and have both guaranteed Twin channel independence water conservancy diversion transmission medium, can guarantee to rotate the series fluid flow that does not take place under the operating mode between the passage again, not outer unloading.Simple in structure, working stability is reliable, especially can satisfy the technological process requirement that useless film reclaims machine.
