Problems solved by technology

However, due to the improper design of the above structure or the epoxy resin pouring process, the seal will fail
In addition, the process of using epoxy resin for sealing is cumbersome and requires high requirements for operators, and there is a certain risk of sealing failure, and the wire diameter of this sealing lead is relatively small, which is mainly used for signal transmission and is not suitable for high current transmission.
The above-mentioned ultra-high pressure sealing lead has extremely high requirements on the operator. In the case of seal failure, cleaning the epoxy resin in the sealing groove is time-consuming and laborious. At the same time, the sealing surface is also easily scratched during the cleaning process, resulting in the failure of the workpiece. use

Embodiment 1

[0025] The present invention provides a lead device, which is particularly suitable for an ultra-high pressure environment. In the present invention, the ultra-high pressure refers to a pressure greater than or equal to 300 MPa or more. In addition, in the present invention, for the convenience of description, the side of the lead device close to the atmospheric environment is referred to as the first side (ie, the upper side), and the side opposite to the first side and close to the ultra-high pressure environment is referred to as the first side. is the second side (ie the lower side).

[0026] like figure 1 As shown, the lead device includes a lead pin assembly 2, a lead pin fitting 1 having a slotted hole matched with the lead needle assembly 2, a first fixing member 5 for fixing the lead needle assembly 2, a lead pin fitting 1 for sealing the lead needle assembly 1. At least two insulating seals 6 and a second fixing element 7 for locking the insulating seals 6 , wherein...

Embodiment 2

[0040] The present invention provides a pressure vessel equipped with a lead device.

[0041] Specifically, the lead device is arranged on the inner wall, cover or other required positions of the pressure vessel (for example, the pressure chamber mentioned below). Since the lead device of this embodiment is the same as the lead device of Embodiment 1, it is omitted. its description.

[0042] In this embodiment, the pressure vessel has a pressure chamber. When the pressure in the pressure chamber of the pressure vessel rises to more than 300 MPa, the lead wire device with the above structure can connect the wires outside the pressure vessel to the ultra-high pressure under pressure. The heating wire in the cavity is connected, and when the pressure chamber of the pressure vessel is kept at an ultra-high pressure, for example, the first end 21 of the lead pin 20 is connected to the wire, and the second end 23 of the lead pin 20 is connected to the heating wire, To achieve inter...

Abstract

The present invention provides a lead device and a pressure vessel having the lead device. The lead device includes: a lead needle assembly, which includes an insulating sleeve and a lead needle sheathed in the insulating sleeve, the lead needle includes a first end, a second end opposite to the first end, and a second end located at the first end and the first end. The main body part between the two ends; the lead pin fitting, which has a slot hole matched with the lead pin assembly, the slot hole includes a first slot hole section for accommodating the lead pin, a second slot hole section for accommodating the main body part, and a third slot hole section. a slotted hole segment; a first fixing member, which fixes the first end portion in the first slotted hole segment; and a second fixing member, which is fixed to the third slotted hole segment; in the first slotted hole segment and the third slotted hole segment, The lead pin and the lead pin fitting are insulated by the first insulating gasket, the second insulating gasket and the insulating sleeve respectively, and the second insulating gasket, the second end and the third slotted hole section are formed with at least two insulating seals filled with them. The sealing space of the part, the second fixing part is used to hold the insulating seal.

Description

technical field [0001] The invention relates to providing a lead device suitable for an ultra-high pressure environment and a pressure vessel with the lead device, which ensures the sealing and insulation of the lead device and the external atmospheric environment under the ultra-high pressure environment, and is easy to assemble. Background technique [0002] High temperature and high pressure laboratory system is an important experimental platform. For a high temperature and high pressure experimental system with a pressure of 300MPa and a temperature of 500-1200℃, continuous and stable heating is the basic requirement of the experimental system. For example, when heating with a heating wire, we are required to provide a lead device that can be used under ultra-high pressure conditions, and this lead device must ensure sealing and insulating properties. The problem of sealing leads of pressure vessels has always been the technical difficulty and key point of pressure vess...
