Description

Technical Field

[0001] The invention relates to the technical field of supercharger throttle holes, and in particular to a supercharger pressure-adjustable throttle hole flange device and an adjustment method thereof. Background Art

[0002] The function of the throttling orifice is to reduce the aperture of the pipe, so that the liquid flow rate at the constriction increases, thereby reducing the pressure. Arranging different throttling orifices according to the pressure difference between the system pressure and the actual pressure required by the device can meet the actual pressure requirements of the device.

[0003] So far, the lubricating oil inlet of the turbocharger on the marine low-speed diesel engine is mainly provided by the lubricating oil of the diesel engine system, and the lubricating oil system pressure of the diesel engine is often higher than the lubricating oil pressure value actually required by the turbocharger. The actual required turbocharger lubricating oil pressure is mainly achieved by reducing the pressure through the throttle orifice plate, so as to avoid excessive lubricating oil inlet pressure of the turbocharger and damage to the turbocharger. However, in actual projects, the single throttle orifice plate aperture needs to be equipped for each machine according to different system pressures, different turbocharger manufacturers and models, and once installed, if the pressure does not match, it is necessary to disassemble the pipeline and re-process the throttle orifice plate with the appropriate aperture, resulting in waste of throttle orifice plates and time cost of disassembling and assembling pipelines.

[0004] To this end, we propose a supercharger pressure-adjustable throttle flange device and an adjustment method thereof. Summary of the invention

[0005] The object of the present invention is to provide a supercharger pressure-adjustable throttle hole flange device and an adjustment method thereof, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a supercharger pressure-adjustable throttle flange device, comprising: a throttle flange, an adjusting screw and a limit assembly, a pipeline is provided in the middle of the throttle flange, an upper hole and a lower hole are provided inside the throttle flange, the upper hole and the lower hole are arranged one after the other, one up and one down, the lower hole is located slightly behind the upper hole, and threads are provided at the ends of the upper hole and the lower hole, an adjusting screw is threadedly connected to the inner wall of the upper hole, the adjusting screw is made into two sections, the lower section is made into a smooth rod, and a sealing ring groove is provided for installing a sealing ring to prevent the lubricating oil inside the sealed throttle flange from flowing out, the upper part is made into a full thread, which is convenient for the up and down adjustment of the adjusting screw, the throttle flange is provided with limit assemblies at both ends of the pipeline, and connecting pipes are provided at the ends of the pipeline, and the connecting pipes are installed in coordination with the limit assemblies.

[0007] Preferably, the outer wall of the adjusting screw is threadedly connected with two tightening nuts, which are used to fix the position of the adjusting screw after the adjusting screw is adjusted so that it no longer changes.

[0008] Preferably, the lower hole is threadedly connected with a pressure gauge, and the pressure gauge is used to monitor the pressure value after the adjustment screw is adjusted in real time and accurately adjust the position of the adjustment screw.

[0009] Preferably, the limit assembly includes: a hollow connecting ring, the throttling hole flange is located at the end of the pipeline and is fixedly connected to a hollow connecting ring, a connecting ring is rotatably connected inside the hollow connecting ring, a threaded track is provided on one side of the connecting ring, and sliding grooves are equidistantly provided on the inner wall of the hollow connecting ring, an extrusion block is slidably connected to the inner wall of the sliding groove, a threaded groove is provided on the side of the extrusion block close to the threaded track, the threaded groove is slidably connected to the threaded track, an extrusion column is fixedly connected to one end of a plurality of extrusion blocks close to each other, a rounded corner is provided at one end of the extrusion column, a bevel gear ring is fixedly connected to the side of the connecting ring away from the threaded track, a bevel gear is rotatably connected inside the hollow connecting ring, and the bevel gear ring is meshingly connected to the bevel gear.

[0010] Preferably, an extrusion groove is provided at one end of the connecting pipe located inside the hollow connecting ring, and a plurality of extrusion columns have rounded corners to extrude an inclined surface on the extrusion groove.

[0011] Preferably, one end of the bevel gear extends out of the hollow connecting ring and is provided with a hexagonal groove.

[0012] Preferably, the throttle hole flange can be designed according to the actual supercharger lubricating oil inlet pipeline to have the same outer diameter, inner hole diameter and connecting bolt hole specifications as the pipeline flange.

[0013] The present invention also provides the following technical solution: a method for adjusting a supercharger pressure-adjustable throttle flange device, the steps of which are as follows:

[0014] Step 1: First, insert the two connecting pipes into the hollow connecting ring respectively, and then insert the hexagonal wrench into the hexagonal groove, and rotate the hexagonal wrench to rotate the bevel gear, and then drive the bevel gear ring to rotate through the meshing connection between the bevel gear ring and the bevel gear, and the bevel gear ring drives the connecting ring to rotate. At this time, the threaded track rotates together, and the extrusion block moves toward the center of the hollow connecting ring under the dual restrictions of the threaded track and the slide groove. At this time, several extrusion blocks move toward the middle, and the extrusion groove on the connecting pipe is squeezed by the rounded corners on the extrusion column, and the inclined surface on the extrusion groove is pressed, so that the connecting pipe is always in close contact with the end of the pipeline to ensure airtightness;

[0015] Step 2: Adjust the adjusting screw. After adjustment, tighten the nut. When the diesel engine is tested, use the pressure gauge on the throttle orifice device to monitor whether the pressure of the pipeline meets the requirements at any time. If the pipeline lubricating oil pressure is too high or too low, loosen the tightening nut and adjust the extension of the adjusting screw again to meet the pressure requirements; if the pipeline pressure is too low, adjust the adjusting screw upwards; if the pipeline pressure is too high, adjust the adjusting screw downwards. The operation is simple and accurate. The entire pressure adjustment process does not require disassembly of the pipeline. You only need to adjust the adjusting screw and tighten the nut. This avoids the design of multiple specifications for different lubricating oil system pressures, different supercharger manufacturers and models, and different throttle orifice plate apertures. It also saves the time cost of re-disassembly and re-processing of the throttle orifice plate when the pressure does not match.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The present invention has universality and can adjust the matching supercharger lubricating oil inlet pressure by adjusting screws according to different supercharger requirements, thereby avoiding the multi-specification design of matching different superchargers with different throttling orifice plates and avoiding the time cost of disassembling and assembling the pipeline. In addition, the throttling orifice flange device is designed with a pressure gauge, which can timely and real-timely feed back the adjusted pipeline pressure when the pressure is adjusted, thereby avoiding the communication and transmission of long-distance monitoring, and the adjustment is accurate and effective.
