Description

Technical Field

[0001] This utility model relates to the field of high-pressure sealing device assembly technology, specifically to a high-pressure stuffing box assembly device. Background Technology

[0002] High-pressure stuffing boxes are critical dynamic sealing components in industrial production, ensuring no leakage of toxic gases and coolants. The assembly of stuffing boxes on the production line requires precision and meticulousness for a good seal; the assembly accuracy directly affects the sealing performance. However, in actual operation… With numerous ends, when the cooling water jacket is installed, the O-rings on the base protrude significantly from the mating surface, requiring forceful hammering of the cooling cylinder. This uneven force application causes severe damage to the sealing end face of the cylinder, making subsequent work impossible. The O-rings are also often cut off due to the hammering, resulting in rework and waste. Furthermore, the numerous stuffing boxes inside the cylinder experience significant tensile stress due to the surface tension of the O-rings used for sealing and compensating for the seals, causing the small ∮6 diameter bolts and tie rods used for positioning to frequently break, leading to complete rework. During the assembly and testing of the stuffing box assembly, the gas pressure and stress conditions of a single stuffing box cannot be simulated offline under normal operating conditions, preventing the implementation of offline pressure tests and failing to achieve the desired results. Therefore, the existing assembly process suffers from the following problems: 1. Traditional assembly relies on hammering, easily causing damage to the sealing end face and O-ring breakage; 2. Frequent breakage of small bolts and tie rods due to uneven force, leading to rework; 3. Inability to simulate actual working conditions of load and pressure offline, resulting in pressure test failure. Therefore, there is an urgent need to design a high-pressure stuffing culvert assembly device to solve the problems of easy damage and breakage from external impacts, easy rework of using thin bolts and tie rods, and inability to conduct offline simulation experiments in the existing technology. Utility Model Content

[0003] In view of the problems existing in the prior art, the purpose of this utility model is to provide a high-pressure filling culvert assembly device.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a high-pressure stuffing culvert assembly device, including a force-bearing frame, a jack assembly, a threaded clamping rod, an annular buckle and a cooling water cylinder. The force-bearing frame is a base, and the jack assembly is movably connected within the force-bearing frame. The threaded clamping rod includes two parts: a radial threaded rod and an axial threaded rod. The annular buckle is located at the bottom of the force-bearing frame, and the cooling water cylinder is fixed within the force-bearing frame by the annular buckle.

[0005] Specifically, the load-bearing frame includes a horizontal support beam and vertical fixed columns, with the vertical fixed columns symmetrically fixed at both ends of the horizontal support beam.

[0006] Specifically, the jack assembly includes a hydraulic jack and a pressure regulating valve. The hydraulic jack is installed in the middle of the horizontal support beam, and a flange is provided on the top of the hydraulic jack. The flange is rigidly connected to the sealing flange.

[0007] Specifically, the pressure regulating valve is connected to the hydraulic jack via an oil pipeline.

[0008] Specifically, the axial threaded rod extends laterally through the vertical fixed columns on both sides of the load-bearing frame, and is fixed by a nut. The radial threaded rod is connected to the axial threaded rod by an adjusting nut at the top of the axial threaded rod.

[0009] Specifically, the annular buckle is an annular structure, with its inner diameter matching the outer diameter of the cooling water cylinder, and the annular buckle is fixed to the upper surface of the horizontal support beam by bolts.

[0010] This utility model has the following beneficial effects:

[0011] This utility model designs a high-pressure packing culvert assembly device that uses mechanical force instead of hammering. When assembling the packing cylinder, the process is uniform and slow, without damaging the cylinder or breaking the O-rings. Assembly is completed in one step, which is fast and efficient, saving manpower and resources. It has strong applicability, and the adjustable diameter threaded clamping rod can assemble a wide range of components by moving the nut. When pressurizing the packing assembly, the combination of jacks and bolt clamping devices within the frame can effectively simulate the load conditions under normal working conditions of the packing, ensuring 100% success in pressurization.

[0015] Example 1:

[0016] like Figure 1As shown, a high-pressure stuffing culvert assembly device includes a load-bearing frame 1, a jack assembly, a threaded clamping rod, an annular buckle 4, and a cooling water cylinder 5. The load-bearing frame 1 serves as a base, and the jack assembly is movably connected within the load-bearing frame 1. The threaded clamping rod includes a radial threaded rod 3 and an axial threaded rod. The annular buckle 4 is located at the bottom of the load-bearing frame 1, and the cooling water cylinder 5 is fixed within the load-bearing frame 1 by the annular buckle 4.

[0017] The load-bearing frame 1 includes two horizontal support beams and two vertical fixed columns. The horizontal support beams and vertical fixed columns are welded together to form the load-bearing frame 1, which is used to fix the various components.

[0018] The jack assembly includes a hydraulic jack 2 and a pressure regulating valve 2.1. The hydraulic jack 2 is located at the bottom of the horizontal support beam on the load-bearing frame 1. The top of the hydraulic jack 2 is equipped with a flange 2.3 and a sealing flange 2.4, which are rigidly connected by bolts. The sealing flange 2.4 is used to press the high-pressure stuffing box, and the hydraulic jack 2 is used to output pressure. The hydraulic jack 2 is equipped with a pressure regulating valve 2.1 on the outside of the hydraulic jack 2. The pressure regulating valve 2.1 is located on the oil pipeline 2.2 of the hydraulic jack 2 and is used to regulate the oil flow to control the pressure output of the hydraulic jack 2.

[0019] The threaded clamping rod includes a radial threaded rod 3 and an axial threaded rod. The radial threaded rod 3 is connected to the axial threaded rod through an adjusting bolt at the head of the axial threaded rod. The axial threaded rod passes through the vertical fixed columns on both sides of the load-bearing frame 1. The radial threaded rod 3 and the axial threaded rod are used to apply pressure to both sides of the high-pressure filling culvert to prevent tilting.

[0020] The ring buckle 4 is located on the upper part of the horizontal support beam at the bottom of the load-bearing frame 1, and is used to fix the cooling water cylinder 5.

[0021] Example 2: Specific implementation steps based on the structural form of Example 1.

[0022] 1. When assembling a high-pressure stuffing box, the hydraulic jack 2 precisely controls the output pressure through the pressure regulating valve 2.1, and applies it evenly to the sealing flange 2.4 through the flange 2.3, replacing the traditional knocking method and avoiding damage to the sealing end face and O-ring breakage;

[0023] 2. The radial threaded rod 3 and the axial threaded rod are linked by the adjusting nut to ensure that the force on both sides of the stuffing box is balanced, eliminating the risk of breakage of the thin bolt tie rod due to eccentric loading;

[0024] 3. The ring buckle 4 secures the cooling water cylinder 5 within the load-bearing frame 1, and, in conjunction with the synchronous adjustment of the threaded clamping rod, achieves precise alignment of the packing assembly;

[0025] 4. During the pressure test, the hydraulic jack 2 simulates the actual working load, and combined with the fixing effect of the threaded clamping rod, the high-pressure environment is reproduced offline to ensure that the sealing performance verification of the stuffing box is successful on the first try.
