Description

Technical Field

[0001] This invention relates to the field of instrument valve technology, specifically to an installation assembly for a high-temperature instrument valve. Background Technology

[0002] An instrument valve is a pipeline accessory used to change the cross-sectional area of ​​a passage and the direction of media flow, controlling the flow of the transported medium. Instrument valves can be classified according to their application as cryogenic valves, low-temperature valves, normal temperature valves, medium-temperature valves, and high-temperature valves. High-temperature instrument valves are typically installed in fluids with high temperatures. Due to the high temperatures during operation, heat-resistant tools may be needed to close the valve when turning it. The sealing performance of an instrument valve refers to its ability to prevent media leakage at each sealing point; it is the most important technical performance indicator. There are three sealing points on an instrument valve: the contact point between the opening / closing element and the valve seat; the mating point between the packing and the valve stem and stuffing box; and the connection point between the valve body and the valve cover. Leakage at the first point is called internal leakage, commonly known as incomplete closure, which affects the instrument valve's ability to cut off the medium. For shut-off valves, internal leakage is unacceptable. Leakage at the latter two points is called external leakage, meaning the medium leaks from inside the valve to outside. External leakage causes material loss, environmental pollution, and in severe cases, accidents. For flammable, explosive, toxic, or radioactive media, external leakage is unacceptable; therefore, instrument valves must have reliable sealing performance.

[0003] Currently, existing high-temperature instrument valves are usually directly exposed on the outside. Due to the high temperature of the equipment itself, workers may get burned. In addition, the equipment itself is easily damaged due to the lack of protective devices. Furthermore, because the fluid controlled by the valve is at a high temperature, the valve itself is also at a high temperature. When workers need to turn it, they need to wear special gloves to work. Moreover, the reuse efficiency of insulated gloves is low, resulting in resource waste. At the same time, the work process is cumbersome and time-consuming. In view of this, we propose an installation component for high-temperature instrument valves. Summary of the Invention

[0004] To overcome the above deficiencies, the present invention provides an installation assembly for a high-temperature instrument valve.

[0005] The technical solution of this invention is:

[0006] An installation assembly for a high-temperature instrument valve includes a housing. A valve body is housed inside the housing. An inlet pipe and an outlet pipe are fixedly connected to both ends of the housing, extending to the outside of the housing. Flanges are fixedly connected to the ends of the inlet and outlet pipes furthest from the valve body. Fixing devices are snapped onto the sides of both the inlet and outlet pipes. The bottoms of both fixing devices are fixedly connected to the housing. A sliding ring is movably connected to the top of the housing via a fixed frustum. A pushing device is fixedly connected to the inner wall of the sliding ring via a heat-insulating ring. A valve stem is located on the top of the valve body, with a pushing device internally meshed with a gear at the upper end of the valve stem. Two heat dissipation devices are located on the top of the housing.

[0007] As a preferred technical solution, the fixed truncated cone has a slot, and the slot is slidably engaged with the sliding ring.

[0008] As a preferred technical solution, the sliding ring is provided with multiple locking posts, the sliding ring is slidably sleeved with the locking posts through grooves, a spring is fixedly connected between the inner wall of the groove of the sliding ring and the locking posts, and the locking posts are engaged with the groove of the fixed truncated cone.

[0009] As a preferred technical solution, the pushing device includes a wrench, and a retaining sleeve is fixedly fitted to the lower end of the wrench.

[0010] As a preferred technical solution, the fixing device includes a lower fixing block and an upper fixing block, both of which are provided with multiple nut holes, and the upper fixing block is movably connected to the nut holes by bolts.

[0011] As a preferred technical solution, the heat dissipation device includes a filter screen, and a cooling fan is fixedly connected to the lower end of the filter screen.

[0012] As a preferred technical solution, a sealing ring is fixedly sleeved on the side of the valve stem, and the sealing ring is rotatably sleeved with the fixed frustum.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. This invention, by setting up a fixing device and a heat dissipation device, has fixing devices snapped onto the sides of both the inlet and outlet pipes. The bottoms of both fixing devices are fixedly connected to the housing. The top of the housing is equipped with two heat dissipation devices. The fixing devices include a lower fixing block and an upper fixing block, both of which have multiple nut holes. The upper fixing block is movably connected to the nut holes by bolts. The heat dissipation device includes a filter screen, and a cooling fan is fixedly connected to the lower end of the filter screen. The upper fixing block and the lower fixing block are fixedly connected by bolts, thus fixing the inlet and outlet pipes on the valve body respectively. Since the fixing devices are fixed to the housing, the valve body is suspended inside the housing. The cooling fan on the heat dissipation device cools the inside of the housing, thus protecting the valve body inside the housing.

[0015] 2. This invention incorporates a wrench and a heat-insulating ring. A sliding ring is movably connected to the top of the housing via a fixed frustum. A pushing device is fixedly connected to the inner wall of the sliding ring via the heat-insulating ring. A valve stem is located on the top of the valve body, with the upper end of the valve stem meshing with a pushing device via a gear. The sliding ring has multiple locking pins, which slide together with the locking pins via grooves. A spring is fixedly connected between the inner wall of the sliding ring's groove and the locking pins. The locking pins engage with the grooves of the fixed frustum. When the valve stem needs to be rotated, the sliding ring moves downwards, causing the wrench and locking sleeve to move downwards until the locking pins reach the grooves within the fixed frustum. The locking pins, via springs, lock the fixed frustum and the sliding ring. The gear groove inside the locking sleeve meshes with gear 12. When the wrench is rotated, the gears drive the valve stem to rotate. When not rotating, the sliding ring can be removed, preventing the locking sleeve from contacting the valve stem. The fixed frustum and the valve body are insulated by the heat-insulating ring.

[0016] 3. This invention uses a housing to install the high-temperature instrument valve as a whole, and the addition of a cooling fan allows for better heat dissipation during operation. Furthermore, the mounting mechanism makes installation more secure and convenient, resulting in better performance. Attached Figure Description

[0030] Please see Figure 1-8 , the present invention provides a technical solution:

[0031] An installation assembly for a high-temperature instrument valve includes a housing 1. A valve body 4 is housed inside the housing 1. An inlet pipe 3 and an outlet pipe 6 are fixedly connected to both ends of the housing 1, extending to the outside of the housing 1. Flange rings 2 are fixedly connected to the ends of the housing 1 and the outlet pipe 6 furthest from the valve body 4. Fixing devices 9 are snapped onto the sides of both the inlet pipe 3 and the outlet pipe 6. The bottoms of both fixing devices 9 are fixedly connected to the housing 1. A sliding ring 13 is movably connected to the top of the housing 1 via a fixed frustum 8. A pushing device 5 is fixedly connected to the inner wall of the sliding ring 13 via a heat insulation ring 16. A valve stem 11 is located on the top of the valve body 4. The upper end of the valve stem 11 is internally engaged with the pushing device 5 via a gear 12. Two heat dissipation devices 7 are located on the top of the housing 1.

[0032] It should be added that the fixed truncated cone 8 has a slot 801, which is slidably connected to the sliding ring 13.

[0033] In a preferred embodiment, the sliding ring 13 is provided with a plurality of locking posts 15. The sliding ring 13 is slidably sleeved with the locking posts 15 through a groove. A spring 10 is fixedly connected between the inner wall of the groove of the sliding ring 13 and the locking post 15. The locking post 15 is engaged with the groove of the fixed truncated cone 8.

[0034] As a preferred embodiment, the pushing device 5 includes a wrench 501, and a retainer 502 is fixedly sleeved on the lower end of the wrench 501.

[0035] As a preferred embodiment, the fixing device 9 includes a lower fixing block 901 and an upper fixing block 902. Both the lower fixing block 901 and the upper fixing block 902 are provided with a plurality of nut holes 903. The upper fixing block 902 is movably connected to the nut holes 903 by bolts.

[0036] It is worth noting that the heat dissipation device 7 includes a filter screen 701, and a cooling fan 702 is fixedly connected to the lower end of the filter screen 701. The cooling fan 702 transfers the internal heat to the outside of the box 1. The bottom of the box 1 is provided with heat dissipation holes, which serve the purpose of heat dissipation inside the box 1.

[0037] As a preferred embodiment, a sealing ring 14 is fixedly sleeved on the side of the valve stem 11. The sealing ring 14 is rotatably sleeved with the fixed truncated cone 8. The sealing ring 14 isolates the heat between the outside of the valve body 4 and the inside of the housing 1, preventing hot air from leaking out and preventing the fixed truncated cone 8 from being heated.

[0038] As a preferred embodiment, the fixed truncated cone 8 is provided with a slot 801, which is slidably engaged with the sliding ring 13. The sliding ring 13 slides within the fixed truncated cone 8, which facilitates the meshing of the pushing device 5 and the gear 12.

[0039] In practical use, the sliding ring 13 is provided with multiple locking pins 15. The sliding ring 13 is slidably sleeved with the locking pins 15 through the groove. A spring 10 is fixedly connected between the inner wall of the groove of the sliding ring 13 and the locking pin 15. The locking pin 15 is engaged with the groove of the fixed truncated cone 8. The locking pin 15 locks the fixed truncated cone 8 and the sliding ring 13 through the spring 10. Without needing to rotate the valve stem 11, the locking pin 15 is moved towards the sliding ring 13 through the cylinder. Then the pushing device 5 is lifted upward, and the sliding ring 13 and the heat insulation ring 16 slide upward. Under the elastic force of the spring 10, the locking pin 15 is pressed tightly against the inner wall of the fixed truncated cone 8, which facilitates the movement of the pushing device 5.

[0040] As a preferred embodiment, the pushing device 5 includes a wrench 501, and a retainer 502 is fixedly sleeved on the lower end of the wrench 501. The retainer 502 meshes with the gear 12 on the valve stem 11 through the internal tooth groove, which facilitates the rotation of the valve stem 11.

[0041] As an optimized installation component for a high-temperature instrument valve according to the present invention, the fixing device 9 includes a lower fixing block 901 and an upper fixing block 902. Both the lower fixing block 901 and the upper fixing block 902 are provided with multiple nut holes 903. The upper fixing block 902 is movably connected to the nut holes 903 by bolts. The purpose of fixing the water inlet pipe 3 and the water outlet pipe 6 inside the housing 1 is achieved by using the grooves of the upper fixing block 902 and the lower fixing block 901.

[0042] As an optimized solution for the installation component of a high-temperature instrument valve according to the present invention, the heat dissipation device 7 includes a filter screen 701, and a cooling fan 702 is fixedly connected to the lower end of the filter screen 701. The cooling fan 702 transfers the internal heat to the outside of the housing 1. The bottom of the housing 1 is provided with heat dissipation holes, which serve the purpose of heat dissipation inside the housing 1.

[0043] As an optimized installation component of a high-temperature instrument valve according to the present invention, a sealing ring 14 is fixedly sleeved on the side of the valve stem 11. The sealing ring 14 is rotatably sleeved with the fixed truncated cone 8. The sealing ring 14 isolates the heat between the outside of the valve body 4 and the inside of the housing 1, so as to prevent hot air from leaking out and to prevent the fixed truncated cone 8 from being heated.

[0044] When using the installation assembly of the high-temperature instrument valve of the present invention, the entire device is first installed. After installation, when the operator needs to close the valve body 4, the sliding ring 13 is moved downwards when the valve stem 11 needs to be rotated. After moving to the appropriate position, the spring 10 locks the locking pin 15 into the groove of the fixed truncated cone 8, fixing the sliding ring 13 to the fixed truncated cone 8. At this time, the sleeve 502 on the pushing device 5 meshes with the gear 12 on the valve stem 11. By rotating the wrench 501, the valve stem 11 can be rotated to achieve the closing function of the valve body 4. At the same time, the sealing ring 14 isolates the heat between the outside of the valve body 4 and the inside of the housing 1, preventing hot air from leaking out and preventing the fixed truncated cone 8 from being heated.

[0045] After the work is completed, the locking pin 15 is moved through the cylinder to the sliding ring 13, and then the pushing device 5 is lifted upward. The sliding ring 13 and the heat insulation ring 16 slide upward. Under the elastic force of the spring 10, the locking pin 15 is pressed tightly against the inner wall of the fixed truncated cone 8. The internal heat is transferred to the outside of the box 1 through the heat dissipation hole by the cooling fan 702. Then, the water inlet pipe 3 and water outlet pipe 6 on the valve body 4 are fixed by the fixing device 9. The valve body 4 does not contact the box 1, which can accelerate heat dissipation.

[0046] Meanwhile, the internal heat is transferred to the outside of the cabinet 1 by the cooling fan 702. The bottom of the cabinet 1 is provided with heat dissipation holes, which serve the purpose of heat dissipation inside the cabinet 1.

[0047] The internal toothed groove of the ferrule 502 meshes with the gear 12 on the valve stem 11, which facilitates the rotation of the valve stem 11.
