Abstract
The utility model discloses a pressure limiting valve of a fuel pump assembly, which includes a valve body and a valve cover that are connected, and is characterized in that a wrapping edge formed through cold punching technology is arranged on the connecting flange surface of the valve body or the valve cover, and fix together the two connecting flange surfaces. As the valve body and the valve cover are connected through the wrapping edge formed through cold punching technology, the pressure limiting valve of the fuel pump assembly has a simple technology and is reliable and firm in connection.
Description
Technical field
The utility model relates to a kind of automobile component, is specifically related to a kind of vehicle fuel pump assembly pressure-limit valve.
Background technique
It is the critical piece of automobile fuel feeding assembly that fuel oil pump assembly is installed in the automotive oil tank, and the effect of fuel oil pump assembly pressure-limit valve is to make the oil return circuit of automobile fuel feeding keep the back pressure of certain pressure value.Present fuel oil pump assembly pressure-limit valve, its valve body and valve gap are to link together through screw, and technology is bad, and it is unreliable to connect, loosening easily in the using process, has a strong impact on the workmanship of pressure-limit valve.
Summary of the invention
To the deficiency that existing technology exists, the purpose of the utility model aim to provide a kind of technology simple, connect reliable tight fuel oil pump assembly pressure-limit valve.
The utility model is implemented through following technological scheme:
The fuel oil pump assembly pressure-limit valve comprises the valve body and the valve gap of connection, and it is characterized in that: the adpting flange mask of valve body or valve gap has the bound edge of cold punching technology moulding, and bound edge is fixed together two adpting flange faces.
In the technique scheme, the adpting flange mask of valve body or valve gap has bound edge, through the bound edge of cold punching technology moulding; Can the adpting flange face of valve body and valve gap is firmly fastening; It is simple that such valve body or valve gap connect technology, connects reliably not become flexible, and effectively guaranteed the workmanship of pressure-limit valve
As preferably, the adpting flange mask of valve body has the bound edge of cold punching technology moulding.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
With reference to accompanying drawing 1, the fuel oil pump assembly pressure-limit valve of the utility model comprises the valve body 1 and valve gap 2 of connection; Valve body 1 is cold-stamped part with valve gap 2, and the adpting flange face 3 of said valve body 1 has bound edge 4, through the bound edge 4 of cold punching technology moulding; Can the adpting flange face 5 of adpting flange face of valve body 3 and valve gap is firmly fastening; It is simple that such valve body 1 or valve gap 2 connect technology, connects reliably and do not become flexible, and effectively guaranteed the workmanship of pressure-limit valve.
Claims (2)
1. fuel oil pump assembly pressure-limit valve comprises the valve body and the valve gap of connection, and it is characterized in that: the adpting flange mask of valve body or valve gap has the bound edge of cold punching technology moulding, and bound edge is fixed together two adpting flange faces.
