Abstract
The utility model discloses a gas compressor volute with an air cock. The air cork is directly arranged on the gas compressor volute in a casting mode. The utility model further discloses an air cork installation module for manufacturing the gas compressor volute with the air cork. Compared with an existing air cork installed through threads and glue, the air cork installation mould is simple in manufacturing technology, low in cost, and little in workload. According to the gas compressor volute with the air cork, the air cork is directly arranged on the gas compressor volute in the casting mode, the problem of insufficient air cork arrangement space due to too many pipelines on the gas compressor volute is relieved, and booster arrangement space is saved. The air cork is flexible in design and does not need installing. Moreover, an inner hole of the air cork is small. An end portion of the air cork is on the same plane with a press shell runner. Noise is little.
Description
Technical field:
The utility model belongs to the dynamic power machine technical field, is specifically related on a kind of compressor volute of gas nozzle and the valve installation mold.
Background technique:
Along with the raising of engine power density, also more and more higher to the compactedness requirement of engine component.For pressurized machine, along with the raising of performance requirement, the assembly on the pressurized machine is also more and more.Originally filled final controlling element, PWM valve, ECRV valve on the compressor volute of spaciousness, how to have arranged reasonably that the pipeline of these assemblies becomes the new problem that hinders the pressurized machine compactness.If can find a kind of method that valve takes up room on the pressurized machine spiral case of compressing, just can solve the not enough problem of the valve arrangement space that causes too much because of pipeline on the compressor volute.The not only arrangement that complicated pipeline can be orderly, and the arrangement space of having saved pressurized machine.
Existing valve mainly contains two kinds of rectangular shape, yi word patterns.But because these two kinds of valve volumes are big, mounting process complexity, suitability are not strong, are difficult to be used for a long time.Complicated along with pressurized machine, the integrated of pressurized machine spiral case and valve will draw attention gradually.
The model utility content:
One of technical problem to be solved in the utility model is to provide a kind of compressor volute of gas nozzle, the compressor volute of this gas nozzle, alleviated the not enough problem of the valve arrangement space that pipeline causes too much on the compressor volute, for the pressurized machine compactness facilitates.
Two of technical problem to be solved in the utility model is to provide the valve installation mold of the compressor volute of making above-mentioned gas nozzle.
Compressor volute as the gas nozzle of the utility model first aspect is characterized in that described valve is cast directly on the compressor volute.
The end of described valve is concordant with the pressure shell runner.
In a preferred embodiment of the present utility model, the fusing point of described valve material therefor is higher than the fusing point of the aluminum alloy material of the compressor volute of casting.
In a preferred embodiment of the present utility model, described valve material therefor is stainless steel material.
Valve installation mold as the compressor volute of the utility model second aspect, comprise pressure shell upper mould, pressure shell mould core and pressure shell lower mould, described pressure shell upper mould and pressure shell lower mould lump together, 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, a locating stud that extends downwards is installed in described valve receiving bore, the end of this locating stud touches the position that pressure shell mould core is installed valve; Hole wall at described valve receiving bore is symmetrically arranged with a pair of spring sheet.
The utility model compared with prior art has following beneficial effect:
The utility model casts from method in the compressor volute body with the stainless steel valve, utilizes the difference of stainless steel and aluminum alloy fusing point, and the stainless steel valve that fusing point is higher casts from the aluminum alloy pressure shell body, realizes the integrated of pressure shell and valve.Compare with the valve that glue is installed with existing dependence screw thread, not only manufacturing process is very simple, and cost is low, workload is few.
The valve of existing use is because endoporus is big, in the pressurized machine high-speed gas by the time be easy to generate abnormal sound.And valve endoporus of the present utility model is little, and the end is concordant with the pressure shell runner, and sound is made an uproar very little.
The utility model has been cancelled the installation procedure of valve, has avoided the space waste that brings because of the valve installation requirements.Its compact structure, technology is simple, and conserve space is with low cost.Alleviate the not enough problem of the valve arrangement space that pipeline causes too much on the compressor volute, also saved the pressurized machine arrangement space simultaneously.
Description of drawings;
Fig. 1 is that valve of the present utility model is installed in the structural representation on the compressor volute.
Fig. 2 is the schematic representation of the utility model mould.
Embodiment:
Further specify the utility model below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1, the compressor volute of the gas nozzle that provides among Fig. 1, its valve 4 is cast directly on the compressor volute 8, and the end of valve 4 is concordant with the pressure shell runner.The fusing point of valve 4 material therefors is higher than the fusing point of the aluminum alloy material of the compressor volute of casting.It for example is stainless steel material.
Referring to Fig. 2, the valve installation mold of the compressor volute that provides among Fig. 2, comprise pressure shell upper mould 1, pressure shell mould core 6 and pressure shell lower mould 7, pressure shell upper mould 1 and pressure shell lower mould 7 lump together, and pressure shell mould core 6 is between pressure shell upper mould 1 and pressure shell lower mould 7; Pressure shell upper mould 1 is provided with a valve receiving bore 1a, and a locating stud 2 that extends downwards is installed in valve receiving bore 1a, and the end of this locating stud 2 touches the 6a place, valve mounting point of pressure shell mould core 6; Hole wall at valve receiving bore 1a is symmetrically arranged with a pair of spring sheet 3.
Utilize above-mentioned mould to realize the valve installation method of compressor volute, specifically comprise the steps:
1, locating stud 2 is installed in the valve receiving bore 1a of pressure shell upper mould 1;
2, valve 4 is enclosed within on the locating stud and by a pair of spring sheet 3 is fixed on the locating stud 2, a baffle plate 5 is installed in the bottom of valve receiving bore 1a again valve receiving bore 1a is sealed;
3, behind 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, an end of casting compressor volute 8 back valves 4 just is deposited in compressor volute 8 inside (referring to Fig. 1).
The utility model is installed on the pressure shell mould inside with the stainless steel valve, utilizes the difference of stainless steel and aluminum alloy fusing point, and valve is cast from pressure shell inside.Realized the integrated of valve and pressure shell.The utility model valve does not need that screw thread is fixed, glue sealing, can directly reach seal request.
