Description
Technical field
The present invention relates to check valve, more particularly to a kind of through type damping check valve component.
Background technology
Traditional electric fuel punp, simple in construction using the noise reduction of damping hole increase back pressure, the structural principle, cost is cheap, lacks
Point be when fuel system changes in flow rate is larger, damping hole produce pressure change it is very big, cause be during fuel system high flow capacity
Pressure of uniting is big, it is impossible to meet fuel system oil spout requirement.Back pressure is inadequate when flow is low, it is impossible to play erasure effect.
The content of the invention
In order to solve the above-mentioned technical problem, the present invention provides a kind of through type damping check valve component, it is ensured that pressure is adjusted
Device rear end back pressure is stable, reduces noise.
To achieve these goals, technical scheme is as follows：A kind of through type damping check valve component, including valve
Right-hand member in shell, the valve casing is equipped with joint, the joint and is provided with oil inlet, and the left end of the valve casing is provided centrally with out
Hydraulic fluid port, in the valve casing built with valve element, damping hole is provided with the valve element, it is characterised in that：The right-hand member set of the valve element
There is valve core case, the inner side aperture of the left end oil-out of the valve casing is provided with guide sleeve, and the valve element left part is reached in guide sleeve,
Valve element and guide sleeve the overcoat pressure spring, the left end of the pressure spring is fixed on the left end of valve casing, and right-hand member passes through valve element
Seat is spacing, and the diameter of the valve core case is less than the internal diameter of valve casing, pressure spring in the raw when, the valve element and joint
End face is fitted, and outside oil-out is also distributed with the left end of the valve casing.
Using such scheme, when flow is smaller, valve element is fitted with joint under the support of pressure spring, passes through the resistance of valve element
Buddhist nun sets up pressure in hole.Pressure oil is gone out by damping hole and center oil outlet.When flow system flow is larger, valve element stress is larger,
Hydraulic drive valve element is moved, and valve element separates with joint binding face, and a part of pressure oil passes through from the outside pressure release of valve element, pressure release oil
Outside oil-out outflow on valve casing；The damping hole pressure release that another part passes through valve element.Flow is with the opening of damping check valve
Shunting is realized, is reduced by by the changes in flow rate of the damping hole of valve element, the change of whole system pressure under changes in flow rate is more solid
Damping hole of the fixed pattern without shunting is stable.The damping hole of valve element is set as that under a relatively low flow back of the body of demand can be produced during design
The damping hole of pressure.Guide sleeve plays a part of being oriented to valve element.
In such scheme, the center line of the guide sleeve and the center line of oil-out, the damping hole of valve element center line with
And the center line of oil inlet is on the same line.It is convenient for assembly.
In such scheme：Oil-out is provided with leg on the outside of the left end of the valve casing.Leg is designed, the damping is prevented
Check valve oil outlet end is shut because assembling.
In such scheme：The valve element is inverted " convex " the shape structure that left part diameter is less than right part diameter, the valve element
Right part major diameter portion diameter be more than guide sleeve aperture.The right part of valve element can not enter in guide sleeve, it is to avoid pressure spring
It is overly compressed in larger flow.
In such scheme：The valve casing, guide sleeve and leg integrated injection molding.
Beneficial effect：The present invention solves the problems, such as that conventional fuel oil is pumped draught control mechanism fluid noise.The damping check valve component
The stabilization of pressure regulator rear end back pressure can be ensured well.In high flow capacity, rear end back pressure is not sharply increased；In low discharge,
Certain back pressure can be also provided, the rate of flow of fluid by pressure regulator is reduced, so as to reduce fluid noise.
