Abstract
The compressor volute of gas nozzle disclosed by the invention, described valve is cast directly on compressor volute.The invention also discloses valve installation mold and the method for the compressor volute manufacturing above-mentioned gas nozzle.The valve that the present invention installs with existing dependence screw thread and glue is compared, and not only manufacturing process is very simple, and cost is low, workload is few.Valve of the present invention directly casts from compressor volute, alleviates the not enough problem of valve arrangement space that on compressor volute, pipeline causes too much, also saves pressurized machine arrangement space simultaneously.This valve flexible design, without the need to install.And valve endoporus is little, end is concordant with pressure shell runner, and sound is made an uproar very little.
Description
Technical field:
The invention belongs to field of power machinery technology, on the compressor volute being specifically related to a kind of gas nozzle and valve installation mold and method.
Background technique:
Along with the raising of engine power density, require also more and more higher to the compactedness of engine component.For pressurized machine, along with the raising of performance requirement, the assembly on pressurized machine also gets more and more.Originally spacious compressor volute has filled final controlling element, PWM valve, ECRV valve, how reasonably to have arranged that the pipeline of these assemblies becomes the new problem hindering pressurized machine compactness.If a kind of method compressed valve on spiral casing of pressure booster and take up room can be found, the not enough problem of the valve arrangement space that compressor volute causes because pipeline is too many just can be solved.The arrangement that not only complicated pipeline can be orderly, and also save the arrangement space of pressurized machine.
Existing valve mainly contains rectangular shape, yi word pattern two kinds.But because these two kinds of valve volumes are large, mounting process is complicated, suitability is not strong, is difficult to be applied for a long time.Complicated along with pressurized machine, spiral casing of pressure booster will draw attention gradually with the integrated of valve.
Summary of the invention:
One of technical problem to be solved by this invention is the compressor volute providing a kind of gas nozzle, the compressor volute of this gas nozzle, alleviates the not enough problem of valve arrangement space that on compressor volute, pipeline causes too much, for pressurized machine compactness provides convenient.
Two of technical problem to be solved by this invention is the valve installation mold providing the compressor volute manufacturing above-mentioned gas nozzle.
Three of technical problem to be solved by this invention is to provide a kind of method utilizing above-mentioned mould to install to realize valve.
As the compressor volute of the gas nozzle of first aspect present invention, it is characterized in that, described valve is cast directly on compressor volute.
The end of described valve is concordant with pressure shell runner.
In a preferred embodiment of the invention, the fusing point of described valve material therefor is higher than the fusing point of aluminum alloy material of casting compressor volute.
In a preferred embodiment of the invention, described valve material therefor is stainless steel material.
As the valve installation mold of the compressor volute of second aspect present invention, comprise pressure shell upper mould, pressure shell mould core and pressure shell lower mould, described pressure shell mould and pressure shell lower mould are combined, and described pressure shell mould core is between described pressure shell upper mould, pressure shell lower mould; It is characterized in that, described pressure shell upper mould is provided with a valve receiving bore, be provided with one to the locating stud of downward-extension in described valve receiving bore, the end of this locating stud touches the position that pressure shell mould core installs valve; The hole wall of described valve receiving bore is symmetrically arranged with a pair spring sheet.
As the valve installation method of the compressor volute of third aspect present invention, specifically comprise the steps:
1, in pressure shell upper mould, locating stud is installed;
2, air tap sleeve is fixed on locating stud by a pair spring sheet on locating stud, then in the bottom of valve receiving bore, one baffle plate is installed valve receiving bore is closed;
3, after pressure shell upper mould, pressure shell mould core and pressure shell lower mould matched moulds, the other end of valve withstands on the valve mounting point of pressure shell mould core;
4, after casting compressor volute, one end of valve is just deposited in compressor volute inside.
The present invention compared with prior art has following beneficial effect:
Stainless steel valve is cast from the method in compressor volute body by the present invention, utilizes the difference of stainless steel and aluminum alloy fusing point, is cast from aluminum alloy pressure shell body by stainless steel valve higher for fusing point, realizes the integrated of pressure shell and valve.The valve installed with existing dependence screw thread and glue is compared, and not only manufacturing process is very simple, and cost is low, workload is few.
The valve of existing use due to endoporus large, in pressurized machine high-speed gas by time easily produce abnormal sound.And valve endoporus of the present invention is little, end is concordant with pressure shell runner, and sound is made an uproar very little.
Present invention eliminates the installation procedure of valve, avoid the space waste brought because of valve installation requirements.Its compact structure, technique is simple, and conserve space is with low cost.Alleviate the not enough problem of valve arrangement space that on compressor volute, pipeline causes too much, also save pressurized machine arrangement space simultaneously.
Accompanying drawing explanation;
Fig. 1 is the structural representation that valve of the present invention is arranged on compressor volute.
Fig. 2 is the schematic diagram of mould of the present invention.
Embodiment:
The present invention is further illustrated below in conjunction with the drawings and specific embodiments.
See the compressor volute of the gas nozzle provided in Fig. 1, Fig. 1, its valve 4 is cast directly on compressor volute 8, and the end of valve 4 is concordant with pressure shell runner.The fusing point of valve 4 material therefor is higher than the fusing point of the aluminum alloy material of casting compressor volute.It is such as stainless steel material.
See Fig. 2, the valve installation mold of the compressor volute provided in Fig. 2, comprise pressure shell upper mould 1, pressure shell mould core 6 and pressure shell lower mould 2, together with pressure shell upper mould 1 is 2-in-1 with pressure shell lower mould, pressure shell mould core 6 is between pressure shell upper mould 1 and pressure shell lower mould 2; Pressure shell upper mould 1 is provided with a valve receiving bore 1a, and in valve receiving bore 1a, be provided with one to the locating stud 2 of downward-extension, the end of this locating stud 2 touches the 6a place, position that pressure shell mould core 6 installs valve; The hole wall of valve receiving bore 1a is symmetrically arranged with a pair spring sheet 3.
Utilize above-mentioned mould to realize the valve installation method of compressor volute, specifically comprise the steps:
1, in the valve receiving bore 1a of pressure shell upper mould 1, locating stud 2 is installed;
2, valve 4 to be enclosed within locating stud and to be fixed on locating stud 2 by a pair spring sheet 3, then in the bottom of valve receiving bore 1a, one baffle plate 5 being installed valve receiving bore 1a is closed;
3, after pressure shell upper mould 1, pressure shell mould core 6 and pressure shell lower mould 7 matched moulds, the other end of valve 4 withstands on the valve mounting point 6a of pressure shell mould core 6;
4, after casting compressor volute 8, one end of valve 4 is just deposited in compressor volute 8 inside (see Fig. 1).
Stainless steel valve is installed on pressure shell mould inside by the present invention, utilizes the difference of stainless steel and aluminum alloy fusing point, valve is cast from pressure shell inside.Achieve the integrated of valve and pressure shell.Valve of the present invention does not need that screw thread is fixed, glue sealing, directly can reach seal request.
