Abstract
The invention discloses a tool for detecting valve body pressure flow performance of a refueling lock cover of an automobile fuel tank. The tool includes a test tank. A pressure sensor and a flow sensor are arranged at each of a left-side gas inlet port and a right-side gas outlet port of the test tank. A valve cover is installed on the test tank in a sealing manner. A fuel injection tube head is fixedly installed on the valve cover and pressed by a pressing block. The refueling lock cover which is internally provided with a valve body function is installed and fastened on the fuel injection tube head according to a loading state. An upper part of the valve cover is provided with a seal cover after being sealed, and the seal cover is compressed through a presser bar and then a windpipe is used to connect the upper part of the seal cover and the right-side gas outlet port of the test tank. The tool for detecting the valve body pressure flow performance of the refueling lock cover of the automobile fuel tank is simple in structure, novel in design, convenient to use and applicable to pressure flow performance test of differently shaped and differently structured refueling lock covers with valve bodies; and through use of the tool, whether the valve body pressure flow performance of a refueling lock cover of an automobile fuel tank is up to standard can be tested and data is accurate and reliable.
Description
Technical field:
The present invention relates to a kind of automobile component device for testing functions, specifically refer to a kind of frock that detects fuel tank of vehicle oiling locking closure valve body pressure flow performance.
Background technology:
The locking closure that refuels is parts that block at automotive oil tank filler, and traditional oiling locking closure mainly rises for nozzle turnover, covers the effect of fuel tank filler (antitheft).Development along with the epoch, to the security performance of automobile, require more and more higher, on market, start to occur that some are with the oiling locking closure of two way valve, this oiling locking closure is more safer than traditional oiling locking closure, when fuel tank is under abnormal condition, when internal pressure is excessive, valve opening, outwards venting, carries out pressure release; While producing negative pressure in fuel tank, valve can be opened, and inwardly inflation, realizes the effect to the pressure in the sealing of fuel tank and trim tank.The at present invention about the oiling locking closure of two way valve function also occurs successively, but how to detect, whether the oiling locking closure valve body pressure flow performance of this function is qualified but never has suitable method.Therefore invent a kind of device that can facilitate testing automobile fuel tank oiling locking closure valve body pressure flow performance, be highly profitable.
Summary of the invention:
The present invention is directed to the problems referred to above a kind of frock that detects fuel tank of vehicle oiling locking closure valve body pressure flow performance, easily and accurately the oiling locking closure pressure flow performance of testing automobile fuel tank band valve are provided.
The technical scheme that the present invention adopted is for achieving the above object: a kind of frock that detects fuel tank of vehicle oiling locking closure valve body pressure flow performance, comprise test tank, at the left side of test tank air intake opening and gas outlet, right side, be provided with pressure transducer and flow sensor, valve gap is installed in the top sealing of described test tank, fixing oiling tube head on described valve gap, with compact heap, compress, after the top sealing of described valve gap, gland bonnet is installed, and compress with compressor arm, with a tracheae, connect described gland bonnet top and gas outlet, described test tank right side.
Further, described valve gap top is provided with O-ring seal.
Preferably, on described oiling tube head, oiling locking closure is installed, then with O-ring seal, gland bonnet, oiling locking closure upper space is sealed, and compress with compressor arm.
Further, the oiling tube head that described oiling tube head is plastic fuel tank.
Preferably, described valve gap and described seal cap sealing are installed.
Further, the parts such as described valve gap and described gland bonnet have formed a confined space, and after described oiling locking closure valve body is opened, gas enters this confined space, and pressure flow is easily detected by pressure transducer and flow sensor.
Further, the valve gap assembling is arranged in described test tank, test tank and valve gap form again an airtight space, air intake opening by test tank during test is constantly ventilated or bleeds in test tank, when the pressure in test tank reaches certain pressure, the valve refueling on locking closure will be opened forward or backwards, by pressure transducer and flow sensor, can test oiling locking closure valve body pressure flow performance parameter.
The present invention is simple in structure, easy to use, is applicable to the pressure flow performance test of the oiling locking closure of difformity different structure, utilizes frock to test, data accurately, reliable, whether the locking closure valve body pressure flow performance of can testing automobile fuel tank refueling qualified.
Accompanying drawing explanation:
Fig. 1 is assembling parts structural representation of the present invention
Fig. 2 is structural representation of the present invention
Embodiment:
Below in conjunction with accompanying drawing, the present invention is described in further detail, is convenient to more clearly understand the present invention, but the present invention do not formed to restriction.
As Fig. 1, shown in Fig. 2, the present invention includes test tank (11), the left side air intake opening (10) of described test tank (11) and gas outlet, right side (12) are provided with pressure transducer (8) and flow sensor (9), it is characterized in that: valve gap (5) is installed in the sealing of described test tank (11) top, the upper fixedly oiling tube head (6) of described valve gap (5), after the sealing of described valve gap (5) top, gland bonnet (1) is installed, and compress with compressor arm (4), with a tracheae (13), connect described gland bonnet (1) top and described test tank (11) gas outlet, right side (12).Described valve gap (5) top is provided with O-ring seal (2).Described oiling tube head (6) is the oiling tube head of plastic fuel tank.Described valve gap (5) is installed with described gland bonnet (1) sealing.
During work, be first that oiling tube head (6) is fixed on to valve gap (5) above, and compress with compact heap (7); Then the oiling locking closure (3) of built-in valve body function is arranged on to oiling tube head (6) according to entrucking state upper, and locking; Then O-ring seal (2) is arranged on to valve gap (5) upper, then gland bonnet (1) is arranged on to O-ring seal (2) top, and compress with compressor arm (4), in oiling locking closure (3) top, form an airtight space.During work, the test tank (11) that the parts that assemble are arranged on is as shown in Figure 2 upper, and test tank and valve gap form again an airtight space.The gas outlet (12) that connects gland bonnet (1) top and test tank (11) right side with a tracheae (13), while testing, air intake opening (10) by test tank (11) is constantly ventilated or bleeds in test tank (11), when the pressure in test tank (11) reaches certain pressure, the valve refueling on locking closure (3) just can be opened forward or backwards, gas enters airtight space, oiling locking closure (3) top, by pressure transducer (8) and flow sensor (9), just can accurately record oiling locking closure (3) valve body pressure flow performance parameter.
