Abstract
The utility model relates to a combination valve for an oil supply system of a high-speed centrifugal blower, which comprises a combination valve body. The combination valve is characterized in that: a first one-way valve, a second one-way valve, an overflow valve, a pressure reducing valve and a throttle valve are arranged in the combination valve body; the overflow valve is respectively connected with the first one-way valve, the second one-way valve and the pressure reducing valve by pipelines; the pressure reducing valve is connected with the throttle valve by the pipeline, and the throttle valve is connected with an outlet by the pipeline. The structure of the combination valve is simple, compact and reasonable; the combination valve integrates multiple functions into one, including one-way, overflow, pressure-reducing, throttling and the like; the combination valve occupies small space, leads high integration in function, and brings great convenience to installation, debugging as well as maintenance work; the appearance is beautiful; as the combination valve is multifunctional in one valve, the cost is low; the performance is good, leakage points are less, and the normal as well as continuous running of the blower at high speed can be ensured.
Description
Technical field
The utility model relates to a kind of combined valve for oil supply system of high-speed centrifugal fan, be used for oil supply system of high-speed centrifugal fan specifically and control the combined valve of oil pressure, flow, guarantee blower fan normal running that continues under high speed, belong to the mechanical structure technical field.
Background technique
In prior art, the oil supply system on the high-speed centrifugal fan is general to adopt independent valve element to be equipped with oil pipe composition oil supply loop.The layout of this kind dispersion not only takes up space greatly, influences aesthetic feeling, and the manufacture cost height, and loosening leakage phenomenon also often takes place at many pipe joints place, and maintenance work is brought very big inconvenience.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, thereby a kind of combined valve for oil supply system of high-speed centrifugal fan is provided, and it will integrate multiple functions such as unidirectional, overflow, decompression, throttling; Institute takes up space little, the functional integration height, and low cost of manufacture, Installation and Debugging and maintenance are very convenient.
The technological scheme that provides according to the utility model, combined valve for oil supply system of high-speed centrifugal fan, comprise combinaing valve body, feature is: be provided with first one-way valve, second one-way valve, relief valve, reduction valve and throttle valve in combinaing valve body, relief valve is connected with first one-way valve, second one-way valve and reduction valve respectively by pipeline; Reduction valve is connected with throttle valve by pipeline, and throttle valve is connected with outlet by pipeline.
Described relief valve connects oil sump.Described reduction valve connects oil sump.
Compared with the prior art the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure; Owing to will integrate multiple functions such as unidirectional, overflow, decompression, throttling; Institute takes up space little, and the functional integration height brings great convenience to Installation and Debugging and maintenance work; Specious, a valve multipotency cost is low, functional, and leakage point is few, can guarantee blower fan normal running that continues under high speed.
Description of drawings
Fig. 1 is the utility model structural principle user mode figure.
Embodiment
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
As shown in Figure 1: comprise combinaing valve body 1 (the first one-way valve 1-1 and the second one-way valve 1-2, relief valve 1-3, reduction valve 1-4 and throttle valve 1-5), auxiliary oil pump 2, main oil pump 3, oil sump 4, first pressure gauge 5, second pressure gauge 6, outlet 7 etc.In combinaing valve body 1, be provided with the first one-way valve 1-1 and the second one-way valve 1-2, relief valve 1-3, reduction valve 1-4 and throttle valve 1-5, relief valve 1-3 by pipeline respectively with oil sump 4, the first one-way valve 1-1, the second one-way valve 1-2, the reduction valve 1-4 and first pressure gauge 5 connect, reduction valve 1-4 is connected with first pressure gauge 5 and throttle valve 1-5 respectively by pipeline, throttle valve 1-5 by pipeline respectively with second pressure gauge 6 and export 7 and be connected, the first one-way valve 1-1 by pipeline respectively with auxiliary oil pump 2, the reduction valve 1-4 and first pressure gauge 5 connect, auxiliary oil pump 2 connects oil sump 4, the second one-way valve 1-2 by pipeline respectively with main oil pump 3, the reduction valve 1-4 and first pressure gauge 5 connect, and main oil pump 3 connects oil sump 4.Described reduction valve 1-4 connects oil sump 4.
The utility model working principle and working procedure:
The utility model is before high-speed centrifugal fan starts, at first should start auxiliary oil pump 2, pressure oil enters reduction valve 1-4 through one-way valve 1-1, the inlet pressure of reduction valve 1-4 is by 5 indications of first pressure gauge, its numerical value is guaranteed by relief valve 1-3, the effect of relief valve 1-3 is to guarantee constant pressure and security of system off-load, the pressure oil that enters reduction valve 1-4 makes oil pressure be reduced to designing requirement and keeps constant through the adjusting of reduction valve, enter throttle valve 1-5 again, make the pressure oil flow of throttling valve outlet port reach designing requirement by the restriction of regulating throttle valve, and will meet flow and pressure (the outlet oil pressure is by 6 indications of second pressure gauge) required pressure oil and send into each lubricant housings by exporting 7, reach the pre-lubrication purpose before the fan starting.Then start blower fan, the main shaft in the blower fan speedup box drives main oil pump 3 and starts simultaneously, and (main oil pump 3 fuel feeding principles are with auxiliary oil pump 2) closes auxiliary oil pump 2 when treating blower fan and main oil pump smooth working, has finished the handing-over of major-minor oil supply system this moment.The pressure oil of each lubricating point flow through oil strainer and cooler enter oil sump 4 at last, thereby form the circulation oil supply loop.
From actual use condition, the utility model is not only specious, and a valve multipotency cost is low; Service behaviour is good, and leakage point is few, brings great convenience to maintenance work.
