In carrying out various electric propulsion engine ground experiment processes, often use metal tubes that propellant feed is arrived test engine.Because self is charged in the electric propulsion engine working procedure, if be on state between the pipeline of motor and supply propellant agent, the electric energy that offers motor in the test will be dissipated on the pipeline greatly, directly influence the engine operation performance even cause motor to work.Therefore, in electric propulsion engine ground experiment propellant-feed system, not only require pipeline bindiny mechanism to realize connection and sealing, assurance liquid and the gas propellant safety supply of pipeline, the supply pipeline that also requires to link to each other with motor has the function of insulation.Simultaneously, in other field, also there is similar demand.
Summary of the invention:
The present invention is directed to the demand that exists in the existing pipeline connection insulation function, a kind of connecting mechanism of sealed insulation pipelines is provided, this pipeline jointing construction adopts and is threaded, end face compresses mode and seals; Adopt the poly-tetrafluoro insulator spacer of particular design simultaneously in the mechanism, guaranteed that the metal tubes that links to each other with these pipeline jointing construction two ends is in state of insulation.Pipeline provided by the invention bindiny mechanism removes possesses that pipeline connects, the function of sealing, guarantees that simultaneously the pipeline that two ends are attached thereto is insulated out.
Technological scheme of the present invention is as follows:
A kind of connecting mechanism of sealed insulation pipelines comprises straight coupling, insulator cap, ball-type joint, the insulation collar and cap nut.
Straight coupling and pipeline pass through welding repeatedly, and link to each other with cap nut by the screw thread on the straight coupling, play the effect of connecting pipeline.
Ball-type joint and pipeline be by being weldingly connected, and be installed in the cap nut, and being threaded by cap nut and straight coupling contacts the bulb of ball-type joint, compress with the conical surface in the straight coupling, plays the effect of sealing.
Ball-type splice insulation cap plays the function that pipeline insulate with the insulation collar.Ball-type splice insulation cap is installed makes bulb joint and straight coupling be in state of insulation; The insulation collar is installed makes bulb joint and cap nut be in state of insulation.
A kind of connecting mechanism of sealed insulation pipelines of the present invention, its advantage and effect are: this pipeline jointing construction adopts thread connecting mode that the two ends pipeline is linked together; Adopting end face to compress mode seals bindiny mechanism is sealed; Adopt the insulating part of poly-tetrafluoro insulating material, realize bulb joint in the bindiny mechanism axially, insulation in the radial direction, guarantee that the metal tubes that links to each other with these pipeline jointing construction two ends is in state of insulation.Sealing insulation pipeline bindiny mechanism is simple in structure, easy to use, is requiring that stronger using value is arranged on the metal tubes Insulation Problems.
Be applicable in the electric propulsion engine test plateau propellant supply system at a cover, adopted above-mentioned connecting mechanism of sealed insulation pipelines, effectively realized the insulation between test engine and the metal propellant supply pipeline.

Embodiment
Below in conjunction with accompanying drawing connecting mechanism of sealed insulation pipelines of the present invention is elaborated.
A kind of connecting mechanism of sealed insulation pipelines of the present invention as shown in Figure 1 and Figure 2, comprises straight coupling 1, insulator cap 2, ball-type joint 3, the insulation collar 4 and cap nut 5.Described straight coupling 1 is the pipe through-hole structure, and outside thread is arranged, as shown in Figure 2, one end of straight coupling 1 is a circular tube structure, is used for being welded to connect with pipeline, and the other end is an external thread structure, be used for being threaded, play the effect that two sections pipelines are connected together with cap nut 5.
Described insulator cap 2 plays the effect of insulation between straight coupling 1 and the ball-type joint 3, is the tapered part that a centre is equipped with circular hole.
Described ball-type joint 3 one ends are circular tube structure, are used for and the pipeline welding, and the other end is a ball head structure, and middle design has a shaft shoulder structure, as shown in Figure 1.
The described insulation collar 4 is for having the cylindrical structure of a boss, and but drum diameter is greater than the diameter of ball-type joint 3 less than the diameter of cap nut 5.Boss and cylindrical portions may are respectively applied for and guarantee that ball-type joint 3 axially, in the radial direction and the insulation between the cap nut 5.
Cap nut 5 is the part of similar and a nut, and just being equipped with one on nut is used for the circular hole that pipeline passes through.
At a side through hole diameter of straight coupling 1 outer worm structure greater than pipe one side diameter, there is one the conical surface 6 one side inside of outer worm structure, preferred 6 one-tenth 37 ° of angles of the conical surface, as shown in Figure 3, when insulator cap 2 and ball-type joint 3 are installed, the bulb part of insulator cap 2 and ball-type joint 3 just is stuck near the taper hole of the conical surface 6 formation, both guarantee the UNICOM sealing between ball-type joint 3 and the straight coupling 1, and utilized insulator cap 2 to guarantee good insulation performance effect between ball-type joint 3 and the straight coupling 1 again.
In mechanism's assembly process, at first one side of the pipe on the straight coupling 1 is welded together with the pipeline that needs to be connected, continue to employ; The insulation collar 4 is enclosed within the cylindrical section of ball-type joint 3, and pass cap nut 5 together, and, notice that the localized hyperthermia that avoids in the welding process welding formation damages the insulation collar 4 that non-metal insulating material is made with the pipe on the spherical joint 3 and the company's for the treatment of metal tube welding; Insulator cap 2 is installed on the conical surface 6 of straight coupling 1, and confirms that ball-type joint 3 bulb metalwork do not surpass insulator cap 2; The insulator cap 2, ball-type joint 3, the insulation collar 4 that have assembled are connected with straight coupling 1 with cap nut 5, and threaded together guarantees that the bulb of ball-type joint 3 partly withstands insulator cap 2 and tightly pushing the conical surface on the straight coupling 1, tightly press the boss structure of the collar 4 that insulate simultaneously between the shaft shoulder of cap nut 5 and ball-type joint 3, so just can realize the sealing and the insulation of bindiny mechanism simultaneously.
