Abstract
The utility model discloses a valve for electrospray fuel pump detection, which comprises a valve seat (1) and a valve body (3); the valve seat (1) is connected with the valve body (3) by a thread; and a seal ring (2) is arranged between the valve seat (1) and the valve body (3). After the technical scheme is adopted, the valve for electrospray fuel pump detection has the advantages that: different requirements of different fuel pumps to be detected on pipelines are met, and quick conversion is realized.
Description
Technical field
The utility model relates to a kind of electric-spraying fuel pump detection and uses valve.
Background technique
At present, in electric-spraying fuel pump detects, all need test the pressure and the flow of oil pump; In test process, need the pipeline of a constant cross-sectional area, the precision that this pipeline must be very is because oil pump is different; Have different requirements for pipes; If product to be detected has had variation, just must change this and close pipeline, make troubles to production.
The model utility content
The problem that the utility model solves provides a kind of electric-spraying fuel pump detection and uses valve, its objective is the convenient electric-spraying fuel pump that detects.
To achieve these goals, the technological scheme taked of the utility model is:
This electric-spraying fuel pump that the utility model provides detects uses valve, comprises valve seat and valve body, and described valve seat is threaded with valve body, is provided with seal ring between described valve seat and the valve body.
Described valve body is a hollow structure, and its cross section is circular.
Described valve body is that the different valve body of a plurality of circulation areas is formed.
The circulation area of said valve body is respectively 0.2mm
2, 0.3mm
2, 0.5mm
2, 1.2mm
2
Adopt technique scheme, this electric-spraying fuel pump that the utility model provides detects uses valve, has the following advantages: realized the demands of different of different fuel pumps to be detected to pipeline, realized Fast transforms.
Description of drawings
Below the mark among expressed content of the accompanying drawing of this specification and the figure is briefly explained:
Fig. 1 is the structural representation of the utility model.
Be labeled as among the figure:
1, valve seat, 2, sealing gasket, 3, valve body.
Embodiment
As shown in Figure 1, this electric-spraying fuel pump that the utility model provides detects uses valve, comprises valve seat 1 and valve body 3, and valve seat 1 is threaded with valve body 3, is provided with seal ring 2 between valve seat 1 and the valve body 3.
Adopt technique scheme, valve seat 1 is a female metalwork in two ends, and an end is used for connecting tube, and the other end is used to connect valve body 3, and valve seat 1 is threaded with valve body 3, and leakage of oil in order to prevent to detect is provided with seal ring 2 between valve seat 1 and valve body 3.
As shown in Figure 1, valve body 3 is a hollow structure, and its cross section is circular.
Valve body 3 is that the different valve body of a plurality of circulation areas is formed.
The circulation area of said valve body is respectively 0.2mm
2, 0.3mm
2, 0.5mm
2, 1.2mm
