For achieving the above object, the utility model provides following technical scheme: a kind of detector for sealing performance of automobile fuel system, include tensimeter, described tensimeter is connected with valve body, valve body is provided with the main channel, for the fuel gauge jointing that valve body is connected to the fuel pipe jointing on the fuel pipe and is used for the Bonding pressure table, described main channel and fuel pipe jointing, the fuel gauge jointing is interconnected, described valve body is provided with two fuel pipe jointings and two fuel gauge jointings, described two fuel gauge jointings are between two fuel pipe jointings, and described valve body is provided with the stop valve of control main channel break-make between two fuel gauge jointings.
By adopting technique scheme, each local fuel pipe in the same oil piping system is connected on the valve body by the fuel pipe jointing, and by being located at the break-make of two stop valve control main channels between the fuel gauge jointing, stop valve is opened the sealing that then detects whole oil piping system; Close stop valve, the main channel is divided into two sections, form two separate detectors, act on different local oil piping systems, to the sealing propertytest of the local fuel pipe of difference, oil piping system does not need the secondary dismounting, only needs the break-make by the control stop valve, can detect quickly and easily partially sealed property and the entire system sealing of fuel system, have advantage convenient to use and easy to detect.
The utility model further is set to: described valve body is connected and composed by stop valve by left and right valve body, a fuel gauge jointing and a fuel pipe jointing are all arranged on the described left and right valve body, and left and right valve body is positioned at the interface of fuel gauge jointing one end for being connected with stop valve; Described stop valve is detachably connected on the interface of left and right valve body.
By adopting technique scheme, that detecting instrument has is easy to process, collection is convenient and use fast and easily advantage.
The utility model further is set to: described stop valve is ball valve.
By adopting technique scheme, simple in structure, good seal performance that ball valve has, and stimulate the menstrual flow in certain nominal that the scope inner volume is less, lightweight, material consumption is few, installation dimension is little, and driving moment is little, and is easy and simple to handle, easily realize the advantage of fast opening and closing.
Below in conjunction with accompanying drawing the utility model is further described.
Description of drawings
Fig. 1 is the structural representation of the utility model specific embodiment detector for sealing performance of automobile fuel system;
Fig. 2 is the use view of the utility model specific embodiment detector for sealing performance of automobile fuel system.
Embodiment
Referring to accompanying drawing 1, the disclosed a kind of detector for sealing performance of automobile fuel system of the utility model, include valve body 1, valve body 1 is provided with main channel 10, fuel pipe jointing 11 and fuel gauge jointing 12, and described main channel 10, fuel pipe jointing 11 and fuel gauge jointing 12 are interconnected; Fast-type detector for sealing performance of automobile fuel system of the present utility model is connected in the fuel system by fuel pipe jointing 11, and tensimeter 2 is installed on the fuel gauge jointing 12, and tensimeter 2 is for detection of the sealing of fuel system; Described valve body 1 is provided with two fuel pipe jointings 11 and 12, two fuel gauge jointings 12 of two fuel gauge jointings are arranged between two fuel pipe jointings 11; Described valve body 1 is provided with the stop valve 3 for control main channel 10 break-makes between two fuel gauge jointings 12; Described stop valve 3 is ball valve; Concrete, described valve body 1 separately forms left and right valve body between two fuel gauge jointings 12, be equipped with a fuel gauge jointing 12 and a fuel pipe jointing 11 on the left and right valve body, left and right valve body is positioned at the interface of fuel gauge jointing 12 1 ends for being connected with stop valve 3.In this specific embodiment, two oral areas of stop valve 3 and the interface of left and right valve body are connected to form detector for sealing performance of automobile fuel system of the present utility model; Stop valve 3 can adopt with the interface of left and right valve body and be threaded, ring flange is connected and grafting etc. removably connects, also can adopt welding or valve body 1 to be processed to form etc. for integral body, but removably connect have collection, transportation and the advantage such as easy to maintenance, adopt dismountable connected mode so the utility model is preferential.
The principle of work of the detector for sealing performance of automobile fuel system in the present embodiment is (such as Fig. 2): the fuel pipe jointing is connected with fuel system.1) fuel system sealing propertytest, stop valve is opened, and the main channel of left and right valve body is in connected state; Fuel from fuel tank out after, cut-out of fuel pump, system is in packing state, the pressure fuel oil enters into the main channel through filter cleaner from the fuel pipe jointing that connects filter cleaner, and goes out from the fuel pipe jointing that connects fuel injector; If system sealing is functional, then two manometric readings variations are in the critical field; Otherwise, if changing, manometric reading exceeds critical field, then there is leakage in illustrative system.
