DETAILED DESCRIPTION

[0032] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0033] Embodiment 1

[0034] This embodiment provides a temperature measuring wire lead-out device, which is used for leading out the temperature measuring wire 7 in the hot isostatic pressing device. The temperature measuring wire lead-out device passes through the water-cooled plate 1 and the plug body 2 of the hot isostatic pressing device. The specific structure of the temperature measuring wire lead-out device is shown in FIG. Figure 1 to Figure 2 , including a cup sleeve 3 and a seal arranged in the cup sleeve 3, the seal includes an elastic base 8 (for example, a polytetrafluoroethylene sealing block) and a sealing elastic gasket 10, a hard elastic gasket 11 (for example, a mica gasket) and a rigid gasket 12 (for example, a metal gasket) stacked in sequence on at least one end face of the elastic base 8, and a plurality of wire penetration holes are opened on the seal, and the plurality of wire penetration holes do not cross each other.

[0035] Compared with the prior art, the lead-out device of the temperature measuring wire provided in this embodiment leads multiple temperature measuring wires 7 out of the hot isostatic pressing device through the lead-out device of a single temperature measuring wire. On the one hand, in the seal, the elastic matrix 8, the sealing elastic gasket 10, the hard elastic gasket 11 and the rigid pad 12 are stacked in sequence, and the elastic component and the rigid component are alternately arranged. This not only can achieve multiple seals, but also can ensure the transmission of force, fully squeeze the elastic component, and further improve the sealing performance; on the other hand, a wire through-hole is opened on the seal, and the temperature measuring wire 7 is protected by the seal. During the temperature measurement process, the temperature measuring wire 7 is regularly arranged in the seal. The contact area between the temperature measuring wire 7 and the seal is large, and the extrusion force on the temperature measuring wire 7 is evenly distributed on its surface, which can increase the friction between the temperature measuring wire 7 and the seal, reduce the damage to the wire insulation layer caused by stress concentration and the short circuit and data distortion caused by wear, without bending and wear, thereby ensuring the temperature measurement stability of the hot isostatic pressing equipment; on the other hand, since the elastic matrix 8, the sealing elastic gasket 10, the hard elastic gasket 11 and the rigid pad 12 are all sheet or block structures, they are easy to process and manufacture in the industrial production process, which can effectively shorten the processing and production cycle, facilitate regular replacement of worn components while reducing the failure rate and the number of loss components.

[0036] It should be noted that, from the perspective of sealing, the upper and lower end surfaces of the elastic base 8 are symmetrically stacked with the sealing elastic gasket 10, the hard elastic gasket 11 and the rigid pad 12, and the elastic base 8 is located in the middle position of the seal, that is, the seal includes a lower rigid pad 12, a lower hard elastic gasket 11, a lower sealing elastic gasket 10, an elastic base 8, an upper sealing elastic gasket 10, an upper hard elastic gasket 11 and an upper rigid pad 12 stacked in sequence.

[0037] In order to achieve a reasonable arrangement of the temperature measuring wires 7 , illustratively, the number of wire through-holes corresponds to the number of temperature measuring wires 7 , that is, only one temperature measuring wire 7 passes through one wire through-hole.

[0038] From the perspective of the arrangement of the temperature measuring wire 7, a plurality of wire through-holes penetrate the sealing member along the axial direction of the sealing member, and the plurality of wire through-holes are arranged in parallel.

[0039] In order to improve the tightness of the combination of each component in the seal, and thus improve the sealing between the seal and the cup sleeve 3, an annular protrusion is provided at the lower end of the inner wall of the cup sleeve 3, and the lead-out device of the above-mentioned temperature measuring wire also includes a pressing plate 5 and a connecting rod 6. The pressing plate 5 is detachably fixedly connected to the upper end of the cup sleeve 3 through the connecting rod 6, the upper end of the seal abuts against the pressing plate 5, and the lower end of the seal abuts against the annular protrusion. A pressing plate 5 hole is opened on the pressing plate 5, and the position of the pressing plate 5 hole corresponds to the position of the wire penetration.

[0040] During the installation of the seal, the elastic matrix 8, the sealing elastic gasket 10, the hard elastic gasket 11 and the rigid pad 12 are first stacked on the annular protrusion of the cup sleeve 3 according to their positions. The annular protrusion can prevent the elastic matrix 8, the sealing elastic gasket 10, the hard elastic gasket 11 and the rigid pad 12 from falling from the cup sleeve 3; then, the pressure plate 5 is covered on the upper end of the seal, and the pressure plate 5 is pressed to move downward. The pressure plate 5 squeezes the seal, so that the height of the seal is reduced, and the elastic matrix 8, the sealing elastic gasket 10, the hard elastic gasket 11 and the rigid pad 12 are in close contact. The elastic matrix 8 and the hard elastic gasket 11 are deformed outward to achieve an external seal between the seal and the cup sleeve 3. At the same time, the elastic matrix 8 and the hard elastic gasket 11 are deformed inward to squeeze the temperature measuring wire 7 to achieve an internal seal between the seal and the temperature measuring wire 7, and the installation of the seal is completed.

[0041] It should be noted that during the installation of the seal, the rigid pad 12 and the sealing elastic gasket 10 can effectively transmit the preload force of the pressure plate 5, drive the elastic base 8 and the hard elastic gasket 11 to deform inward and outward at the same time, thereby ensuring that the internal and external seals are effective at the same time; in addition, the pressure plate 5 is used to provide a certain preload force for the seal, which can reduce the impact of temperature and pressure increase and decrease in the hot isostatic pressing equipment on the pressure of the seal, avoid the movement of the seal during service, and reduce the wear of the seal. Due to the existence of the preload force, no relative movement is generated between the elastic base 8, the sealing elastic gasket 10, the hard elastic gasket 11 and the rigid pad 12, and in the radial plane of the temperature measuring wire 7, the deformation of the elastic base 8 or the hard elastic gasket 11 is the same, thereby avoiding the temperature measuring wire 7 from pulling out due to relative movement during the repeated pressure increase and decrease of the hot isostatic pressing equipment.

[0042] In order to improve the sealing performance between the elastic base 8 and the cup sleeve 3, the sealing member further includes an inner hole sealing ring 9, which is sleeved on the outer wall of the elastic base 8 and located between the elastic base 8 and the cup sleeve 3. In this way, the initial sealing between the elastic base 8 and the cup sleeve 3 can be achieved by setting the inner hole sealing ring 9, and the axial sealing between the inner surface of the cup sleeve 3 and the outer surface of the elastic base 8 is ensured under the action of pressure, and as the pressure in the hot isostatic pressing equipment increases, the pressure of the pressing plate 5 on the sealing component increases to form a self-tightening seal.

[0043] In order to prevent the inner hole sealing ring 9 from axial displacement during the installation of the sealing element, an outer wall groove is provided on the outer wall of the elastic base 8, and the inner hole sealing ring 9 is located in the outer wall groove.

[0044] Similarly, in order to provide sealing between the cup sleeve 3 and the water-cooled plate 1 of the hot isostatic pressing equipment, the outer wall of the cup sleeve 3 is in a stepped shape, that is, the outer wall of the cup sleeve 3 is divided into an external section and an internal section connected sequentially from top to bottom, and the outer diameter of the external section is larger than the outer diameter of the internal section, thereby forming a stepped shape, and the lower end surface of the protruding part of the external section contacts the upper end surface of the water-cooled plate 1. In this way, the vertical gap between the cup sleeve 3 and the water-cooled plate 1 can be sealed by the stepped outer wall of the cup sleeve 3, thereby improving the sealing of both.

[0045] The lead-out device of the temperature measuring wire also includes an end face sealing ring 4, which is located between the external section and the water-cooled plate 1. The lower end face of the external section also has an end face groove, and the end face sealing ring 4 is located in the end face groove.

[0046] Furthermore, the cup sleeve 3 is shaped as a hollow cylinder, wherein the outer wall of the cup sleeve 3 is stepped, divided into a first outer wall section, a second outer wall section and a third outer wall section which are connected in sequence from top to bottom, wherein the first outer wall section is an external section, the second outer wall section and the third outer wall section are internal sections, the outer diameters of the first outer wall section, the second outer wall section and the third outer wall section decrease gradually, and the end face groove is arranged on the lower end face of the first outer wall section; the inner wall of the cup sleeve 3 is stepped, divided into a first inner wall section, a second inner wall section and a third inner wall section (i.e., an annular protrusion), the outer diameters of the first inner wall section, the second inner wall section and the third inner wall section decrease gradually, the pressure plate 5 is placed on the upper end face of the second outer wall section, the first inner wall section is used to accommodate the pressure plate 5, the seal is placed on the upper end face of the third inner wall section, the second inner wall section is used to accommodate the seal, the second inner wall section is tightly fitted with the seal, and the third inner wall section serves as an annular protrusion for supporting and limiting the seal. On the one hand, the stepped outer wall can ensure a tight fit between the outer wall of the cup sleeve 3 and the water cooling plate 1 and the plug body 2. On the other hand, the stepped inner wall can support and accommodate the seal and set the preload force of the pressure plate.

[0047] Embodiment 2

[0048] This embodiment provides a method for leading out a temperature measuring wire 7, using the temperature measuring wire leading out device provided in the first embodiment, and the leading out method includes the following steps:

[0049] Place the cup sleeve 3 in the water cooling plate 1 and the plug body 2;

[0050] Pass the temperature measuring wire 7 through the wire hole;

[0051] The sealing member is placed in the cup sleeve 3 to complete the lead-out of the temperature measuring wire 7 .

[0052] Compared with the prior art, the beneficial effects of the method for leading out the temperature measuring wire 7 provided in this embodiment are substantially the same as the beneficial effects of the device for leading out the temperature measuring wire provided in the first embodiment, and are not described in detail here.

[0053] Based on the specific structure of the extraction device, the extraction method specifically includes the following steps:

[0054] Step 1: placing the end face sealing ring 4 in the end face groove of the first outer wall segment;

[0055] Step 2: Place the cup sleeve 3 in the water-cooled plate 1 and the plug body 2, the end face sealing ring 4 is located between the first outer wall section and the water-cooled plate 1, and the lower end face of the first outer wall section of the cup sleeve 3 contacts the upper end face of the water-cooled plate 1;

[0056] Step 3: Pass the lower end of the temperature measuring wire 7 through the upper rigid pad 12, the upper hard elastic pad 11, the upper sealing elastic pad 10, the elastic base 8, the lower sealing elastic pad 10, the lower hard elastic pad 11 and the lower rigid pad 12 in sequence;

[0057] Step 4: The lower rigid pad 12, the lower hard elastic pad 11, and the lower sealing elastic pad 10 are sequentially placed in the cup sleeve 3, wherein the lower end surface of the lower rigid pad 12 contacts the upper end surface of the third inner wall segment;

[0058] Step 5: Place the inner hole sealing ring 9 in the outer wall groove of the elastic base 8, and place the elastic base 8, the upper sealing elastic gasket 10, the upper hard elastic gasket 11 and the upper rigid pad 12 in the cup sleeve 3 in sequence. At this time, the upper end surface of the upper rigid pad 12 protrudes from the upper end surface of the second inner wall section, and the outer walls of the lower rigid pad 12, the lower hard elastic gasket 11, the lower sealing elastic gasket 10, the elastic base 8, the upper sealing elastic gasket 10, the upper hard elastic gasket 11 and the upper rigid pad 12 are in contact with the inner wall of the second inner wall section of the cup sleeve 3;

[0059] Step 6: Pass the upper end of the temperature measuring wire 7 through the pressing plate 5 hole on the pressing plate 5;

[0060] Step 7: placing the pressing plate 5 on the upper end surface of the rigid pad 12 and the upper end surface of the second inner wall section of the cup sleeve 3;

[0061] Step 8: straighten the temperature measuring wire 7 from both ends of the temperature measuring wire 7, and ensure that the temperature measuring wire 7 has a certain pre-tightening force. On the one hand, it can prevent the temperature measuring wire 7 from being clamped between the contact surfaces of the various components of the seal or between the contact surfaces of the seal and the pressure plate 5. On the other hand, the setting of the pre-tightening force can also adapt to the subsequent compression deformation of the seal;

[0062] Step 9: Pass the connecting rod 6 through the connecting hole on the pressure plate 5 and connect it to the upper end surface of the cup sleeve 3, tighten the connecting rod 6, press the pressure plate 5 to move downward, the pressure plate 5 squeezes the seal, so that the height of the seal is reduced, and the seal is completely pressed into the second inner wall section. The elastic matrix 8, the sealing elastic gasket 10, the hard elastic gasket 11 and the rigid pad 12 are in close contact, the elastic matrix 8 and the hard elastic gasket 11 are deformed outward to achieve the external seal between the seal and the cup sleeve 3, and at the same time, the elastic matrix 8 and the hard elastic gasket 11 are deformed inward to squeeze the temperature measuring wire 7, to achieve the internal seal between the seal and the temperature measuring wire 7, and complete the lead-out of the temperature measuring wire 7.

[0063] It should be noted that the use of the above method to lead the temperature measuring wire 7 out of the hot isostatic pressing equipment can effectively ensure the tightness of the fit of various components, and at the same time, can also ensure that the force on the temperature measuring wire 7 is uniform.

[0066] Compared with the prior art, the beneficial effects of the hot isostatic pressing equipment provided in this embodiment are substantially the same as the beneficial effects of the lead-out device for the temperature measuring wire provided in the first embodiment, and are not described in detail here.
