Description
Technical field
The utility model relates to a kind of pressure regulator, relates in particular to the pressure regulator of a kind of pressure maintaining performance height, long service life.
Background technique
Pressure regulator is installed in the oil return system of vehicle fuel supply system; Be used for keeping the predetermined oil pressure value of internal system; So that oil pump is realized starting fast and under the automobile working state when system oil pressure is too high pressure release come the regulating system oil pressure; And rapid throttle down when fuel pump cuts out keeps residual pressure.The working principle of existing pressure valve is: the centre of metal shell is divided into two cells through seal membrane with the housing inner chamber, and one is spring housing, in adorn a band pretightening force helical spring act on the diaphragm; Another chamber is the fuel oil chamber, directly is connected into the fuel feeding house steward.When the oil pressure that enters people's fuel oil chamber when fuel feeding house steward's fuel oil surpasses predetermined numerical value; Fuel pressure just turns down seal membrane, valve ball seat and valve ball together; Overcome spring pressure; Make valve open, the fuel oil of the indoor surplus of fuel oil gets into return tube through the valve inner via hole and is back in the fuel tank, thereby the oil pressure of fuel feeding house steward and pressure regulator fuel oil chamber is remained on the predetermined oil pressure value.Yet; This kind pressure regulator is in use because not process filtration of oil-feed; Can make the impurity that produces because of the oil pump wearing and tearing directly get into pressure valve fuel oil chamber, those impurity can scratch counterface and stick on the valve end face and the valve ball end face on, pressure regulator can't cut out fully; Cause pressure maintaining performance low, automobile starts ability drop fast.And the serious wear that is caused by impurity influences the working life of pressure regulator.
The model utility content
The purpose of the utility model is to provide a kind of pressure regulator, and is low with pressure regulator pressure maintaining performance in the solution existing technology, the technical problem that working life is short.
For achieving the above object; The utility model provides a kind of pressure regulator; Comprise: upper valve body, following valve body, valve, first valve ball, filter screen, seal membrane, second valve ball, valve ball seat, spring seat, little spring and pagoda spring; Be respectively arranged with filler opening and oil outlet on the said upper valve body, said valve body down is connected with said upper valve body snapping; Said seal membrane is arranged on said upper valve body and said valve body joint down, forms the fuel oil chamber with said upper valve body inner chamber, and forms spring housing with said body cavity down; Said valve is arranged on the indoor and said oil outlet socket of said fuel oil and is connected; Said first valve ball connects in said oil outlet place and said valve sleeve in succession; Said filter screen is arranged on the indoor cover of said fuel oil and is connected to said valve bottom; Said valve ball seat is connected with said seal membrane socket; Said second valve ball and said little spring are separately positioned in the said valve ball seat, and said little spring is connected with said second valve ball bottom, and the said second spring top is connected to said valve; Said spring seat and said pagoda spring are arranged in the said spring housing, and said spring seat and said valve ball cover for seat connect in succession, and said pagoda spring is connected to said spring seat.
According to the described pressure regulator of the utility model preferred embodiment, it also comprises a seal washer, and said seal washer is connected with said upper valve body socket.
According to the described pressure regulator of the utility model preferred embodiment, it also comprises an O type circle, and said O type circle and said valve sleeve connect in succession.
The technological scheme of the utility model is improved the structure of existing serial pressure regulator; In the pressure regulator indoor design filter screen is installed; Effectively controlled and got into the indoor fuel oil cleaning of fuel oil, make valve, valve ball end face no longer by impurity scratch, bonding, can be rapidly, close effectively; Thereby improve system's pressure maintaining performance, prolong the working life of pressure regulator.Therefore, compared with prior art, the utlity model has the advantage of pressure maintaining performance height, long service life.
