Description
Technical Field
The utility model relates to a fuel tank, in particular to valve for fuel tank.
Background
The combined valve is a hydraulic device with the functions of unloading, safety, check and the like, combines a plurality of valves used on an automobile fuel tank, and has the advantages of high integration degree, small volume, compact structure, good sealing property, large flow capacity and long service life, so the combined valve is widely applied to an automobile oil supply device.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a fuel tank is with external welding formula combination valve separately sets up two functional valves, is favorable to the maintenance of valve, and the fixed mode of same external welded is favorable to the installation of combination valve.
The purpose of the utility model is realized like this: the utility model provides an external welding formula combination valve for fuel tank, includes refueling control valve and rollover valve, refueling control valve and rollover valve install the bottom at the mounting panel, the mounting panel includes the roof installation department, and the bottom periphery of roof installation department is provided with the sealing strip, roof installation department top surface is connected with exhaust portion, tubular exhaust portion processes into three-way construction, and three-way construction's by-pass is followed roof installation department bottom and is stretched out, is connected refueling control valve, and three-way construction's through-pass connects rollover valve, another way and regards as the gas vent.
Compared with the prior art, the beneficial effects of the utility model reside in that, the utility model discloses a with refueling control valve and rollover valve through separately installing, the three-way pipe is accomplished in the cooperation and is ventilated to strengthened the inside relative independence of combination valve, be favorable to the installation, the change of two valves, set up the sealing strip in roof installation department bottom simultaneously and strengthened the utility model discloses leakproofness during the installation. The utility model discloses can be used to in the car fuel tank.
As the improvement of the utility model, the one end that the tee bend structure connects the rollover valve is connected with circular boss, and circular boss inner chamber is linked together with the tee bend, the rollover valve is fixed on circular boss inner chamber inner wall. The structure is beneficial to the installation of the rollover valve, and the exhaust is more convenient.
As the improvement of the utility model, the rollover valve mounting height is higher than the mounting height of the refueling control valve. The design avoids the liquid level to cause the influence to the rollover valve.
As the improvement of the utility model, the tip periphery processing that is close to the gas vent in the exhaust portion has the chimb, the chimb is provided with the twice. The convex edge structure is more convenient when the exhaust part is externally connected with other pipelines.
As the improvement of the utility model, the roof installation department is circular structure, exhaust portion is the tubular structure.
