Embodiment 1

[0047] Such as Figure 1-3 The shown one-hole multi-wire high-voltage container lead device includes a housing 1, a wire 2, a pressing plate 3, and a tie rod 4. The housing 1, the pressing plate 3 and the tie rod 4 are all made of conductive metal materials, and the lead 2 Is an enameled wire; the pull rod 4 includes an integrally formed cylindrical portion 41 and a tapered portion 42, a pressure plate 3 is movably arranged at the top of the housing 1, a pull rod 4 and a wire 2 are arranged in the housing 1, the pull rod 4 The pressure plate 3 is connected to the housing 1, and the wire 2 is fixed in the housing 1 through a tie rod 4; the pressure plate 3 is fixed to the top of the housing 1 by a threaded connection, and both ends of the pressure plate 3 are respectively provided with first mounting holes, A second mounting hole corresponding to the cylindrical portion 41 is arranged in the middle; a screw 8 is movably arranged at both ends of the top of the housing 1, one end ...

Embodiment 2

[0052] A method for using a one-hole multi-line high-pressure vessel lead device is as follows:

[0053] Fix a plurality of wires 2 in the interlayer between the first tapered ring 6 and the second tapered ring 7 along the circumferential direction, and put the first tapered ring 6 and the second tapered ring 7 into the second through hole 52, One end of the wire 2 is led out from the bottom end of the housing 1, and the other end is led out from the top of the housing 1 through the first through hole 51; align the pull rod 4 with the through hole 5 through the through hole 5 from bottom to top to the tapered part 42 completely enters the second through hole 52, and the first tapered ring 6, the wire 2 and the second tapered ring 7 are pressed on the inner wall of the second through hole 52 through the tie rod 4; one end of the cylindrical portion 41 of the tie rod 4 The second mounting hole extending to the outside of the housing 1 and passing through the pressing plate 3 is con...

Embodiment 3

[0055] The use method of a one-hole multi-wire high-pressure container lead device is basically the same as that of Embodiment 2, except for the following technical features: the lead device is inserted into the high-pressure container before the formal work, the lead 2 is further removed by the pressure clamp 13 The ground is compacted in the interlayer between the first tapered ring 6 and the second tapered ring 7. Such as Figure 4 As shown, the pressure holder 13 includes a hollow cylinder 131, a pressure cap 132, and a pressure delivery port 133. Both ends of the hollow cylinder 131 are movably provided with a pressure cap 132, and the side wall of the hollow cylinder 131 is provided with There is a pressure delivery port 133, which is connected to a pressure pump through a pipe, and inputs water or oil to the hollow cylinder 131 through the pressure pump; the two ends of the hollow cylinder 131 are equipped with lead devices through pressure caps 132, respectively, The wi...

Abstract

The invention discloses a one-hole and multi-wire high-pressure container lead device and a use method thereof. The lead device comprises a shell, a wire, a pressing board and a pull rod; the pressingboard is movably arranged at the top end of the shell; the pull rod and the wire are arranged inside the shell; the pull rod is connected with the shell through the pressing board; the wire is fixedin the shell through the pull rod; and a through hole is formed in the shell in the axis direction. The one-hole and multi-wire high-pressure container lead device is simple and reasonable in design structure, a lead hole is of a conical structure, a big-area end face bears pressure, and the pressure action causes deformation of a sealing material to generate sealing in a working state. The higherthe pressure is, the more compact the lead device is; and at the same time, due to the conical stress structure, the potential safety hazard that a lead component flies out at a high speed in the useprocess is avoided. A lead set of the lead device is convenient to replace, and can be replaced with a new lead set only by replacing small and big teflon conical rings and epoxy resins.

Description

Technical field [0001] The invention relates to the technical field of pressure vessel sealing in mechanical engineering, in particular to a one-hole multi-line high-pressure vessel lead device and a method of use thereof. Background technique [0002] In scientific research or production activities related to high pressure, it is often necessary to perform in-situ measurement of the physical or chemical parameters of material objects in a high-pressure environment. The sensor is directly placed in a high-pressure environment, and the measurement signal needs to be transmitted to the measuring instrument outside the high-pressure vessel through the measurement lead. Leading the measurement signal from the inside of the high-pressure vessel to the outside of the high-pressure vessel requires a special lead device. How to achieve safe, simple and effective lead-out of multiple measuring lines is a technical problem related to the structure of the lead device. [0003] There are cur...
