Description
Technical field
The utility model relates to pipe joint, especially relates to the swivel joint in the flowing medium delivery line.
Background technique
In order accurately to grasp the variation of ocean environment parameter, needing at sea, the seawater sample of collection in worksite different depth also aboard ship detects in the laboratory immediately.The seawater sample collection of prior art mainly utilizes hydrophore to finish.Usually hydrophore is put in the water by wirerope, after respective depth is adopted water, carries backwater surface again, and the seawater in the hydrophore is used for the laboratory and detects.Utilize hydrophore to adopt water, can not carry out continuously automatically, and it is also limited to adopt the water yield, make troubles for comprehensive marine monitoring operation.
The seawater sample of researching and developing peculiar to vessel is gathered automatically with distribution system and is gathered water sample by sampling pump and the water tube hose of adopting that is put in the water.Adopt water tube hose and be wrapped on the electric capstan, by the folding and unfolding that water tube hose is adopted in the rotation realization of electric capstan, sample at marine different depth, the water sample of collection is transported on the ship by pipe and detects in the laboratory.Because the sampling flexible pipe is wrapped on the electric capstan, finish above-mentioned water sampling and course of conveying, needs one and is installed in the swivel joint that can be communicated with follow-up pipeline on the capstan winch with the synchronous rotation of capstan winch again.And, in order to guarantee to detect the authenticity and the accuracy of data, also require this joint not cause any pollution to the water sample of gathering.
Therefore, one of key technology of automatic collection of seawater sample peculiar to vessel and distribution system is pollution-free swivel joint.
Summary of the invention
Utilize hydrophore to gather the existing problem of seawater sample at prior art, the utility model has been released a kind of swivel joint that the requirement of rotating is arranged of satisfying, be connected with the water tube hose of adopting on being wrapped in electric capstan, realize that water tube hose is adopted in utilization and water pump carries out the automatic collection of marine different depth water sample.
The related pollution-free swivel joint of the utility model comprises hollow shaft, bearing, fittings body.
The hollow shaft front portion is the hollow shaft ladder, and three stair-stepping hollow cylinders are arranged by order from coarse to fine, and front end is the thinnest.The hollow shaft rear portion is the hose plug that has flange, and hose plug is communicated with the hollow shaft ladder is hollow.
Fittings body is a funnel-shaped structure, and the front end of hopper housing is a hose plug, and hose plug is communicated with hopper housing is hollow, and funnel inner chamber end has two annular ditch grooves.
Bearing housing is on the hollow shaft ladder periphery of hollow shaft front portion, and the rear portion of hollow shaft ladder is with star seal ring I, and the front portion of hollow shaft ladder is with shaft block ring and two star seal ring II.The star sealing ring material is a fluorine rubber star seal ring.The hollow shaft ladder of hollow shaft front portion passes the circular hole of bearing (ball) cover and bearing centre, inserts in the fittings body hopper housing.The star seal ring I that is enclosed within hollow shaft ladder rear portion places in the groove of bearing (ball) cover center hole inwall, two star seal ring II that are enclosed within hollow shaft ladder front portion place respectively in two annular ditch grooves of funnel inner chamber end, and the shaft block ring that is enclosed within hollow shaft ladder front portion is near bearing.
Adopt 0 shape seal with elastometic washer between fittings body and the bearing (ball) cover, and rely on bolt that both are fastening.Fittings body is the stationary fixing part, and its outer rim flange firmly is connected with bolt with fixed capstan winch frame.Hollow shaft is a rotating motion part, reliably is connected with winch drum by the outer rim flange, and rotates with winch drum.
During the actual use of the related swivel joint of the utility model, hollow shaft rear portion hose plug inserts in the sampling flexible pipe that is wrapped on the electric capstan, and the hose plug of fittings body front end inserts in the delivery hose.The electric capstan rotation discharges the sampling flexible pipe that is wrapped on the capstan winch and stops to the appointment depth of water, and in this process, the sampling flexible pipe of hollow shaft on winch drum and cylinder rotates, and fittings body and water outlet sampling pipe are motionless.Start sampling pump, the seawater of respective water depth enters hollow shaft rear portion hose plug by the sampling flexible pipe, through inserting the hose plug that the anterior hollow shaft ladder of the interior hollow shaft of fittings body hopper housing enters fittings body hopper housing front end, the delivery hose through being connected with fittings body hopper housing front end hose plug enters laboratory on the ship then again.
Hollow shaft and fittings body adopt that stable chemical performance, corrosion resistance are good, intensity and the good PVC plastic production of mechanical processing characteristic, and the star seal ring that the front and rear of hollow shaft ladder is with is made for the fluorine rubber material.Therefore, all component that contacts with the seawater medium of carrying in the swivel joint all adopt plastics such as the PVC of corrosion-resistant not contaminated-fluid medium or fluorine rubber to make, or have carried out effective partition with above-mentioned material, satisfy the requirement of not polluting the conveying seawater sample.
Dynamic and static seal approach between hollow shaft, fittings body, the bearing (ball) cover three, can effectively cut off in fittings body and hollow shaft on metallic material such as bearing, shaft block ring contact with the seawater medium, and guarantee the reliability of joint at sound two states lower seal.
This swivel joint can be used safely under hydrodynamic pressure ≯ 2bar, capstan winch rotating speed ≯ 120rpm situation, realizes the automatic continuous acquisition of different depth water sample in the comprehensive marine monitoring.
