Abstract
The utility model relates to a detection device for detecting the air tightness of an engine cylinder head, which comprises a gas source. The gas source is connected with a pressure regulating valve and the pressure regulating valve is connected with an electromagnetic reversing valve. The electromagnetic reversing valve is respectively connected with the two ends of a master cylinder. The master cylinder is connected with an auxiliary cylinder and the auxiliary cylinder is connected with a pressure gauge and a measuring head. The electromagnetic reversing valve is also connected with a power supply unit. The device has the advantages of simple structure and convenient operation. Due to the adoption of the device, the air tightness can be tested without the need of being under water. Thus, the rust problem of the parts of an engine cylinder head due to the reason that the air tightness of the engine cylinder head needs to be tested under water in the prior art is solved.
Description
Technical field
The utility model relates to detection range, relates in particular to a kind of engine cylinder head airtight detecting apparatus.
Background technology
Because can there be casting flaws such as trachoma that naked eyes can't distinguish, shrinkage cavity in engine cylinder head in casting process; Therefore need carry out air-tight test to the motorcycle engine cylinder head; Prior art is after the engine cylinder head is installed part; Lead to and go up the artificial situation that emits that gas is put into the air intake opening of water tank detection of engine cylinder head, exhausr port bubble, judge whether have the gas leakage situation to exist with this.But after the test, engine cylinder head and other part are prone to get rusty in water, and the reparation that engine cylinder head is put into water tank and unacceptable product is wasted time and energy, and can produce loss to part simultaneously.
The utility model content
The applicant provides a kind of engine cylinder head airtight detecting apparatus to above-mentioned shortcoming of the prior art, avoided the engine cylinder head parts get rusty and assemble after the accessory loss problem of doing over again and causing.
The technical scheme that the utility model adopted is following:
A kind of engine cylinder head airtight detecting apparatus comprises a source of the gas, and source of the gas connects pressure regulator valve, and pressure regulator valve is connected with solenoid directional control valve, and solenoid directional control valve is connected with the two ends of master cylinder respectively, master cylinder auxiliary connection cylinder, and countercylinder connects tensimeter and gauge head; Solenoid directional control valve also connects supply unit.
It is further characterized in that:
Said supply unit comprises a power supply, and power supply connects switch;
Said gauge head adopts elastomeric material to process;
Said solenoid directional control valve is two position-5 way valves.
The beneficial effect of the utility model is following:
The utility model is simple in structure, easy to operate, need not get in the water and test, and solves and need engine cylinder head be put into water, the problem that causes the engine cylinder head parts to get rusty for the impermeability of test engine cylinder head in the past; And whole testing process is time saving and energy saving, has improved work efficiency.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing, the embodiment of the utility model is described.
As shown in Figure 1, the utility model comprises a source of the gas 1, and source of the gas 1 connects pressure regulator valve 2, and pressure regulator valve 2 is connected with solenoid directional control valve 10, and solenoid directional control valve 10 is connected with the two ends of master cylinder 4 respectively.Master cylinder 4 auxiliary connection cylinders 3, countercylinder 3 connects tensimeter 5 and gauge head 6, and gauge head 6 adopts elastomeric material to process.Solenoid directional control valve 10 also connects supply unit.Supply unit comprises a power supply 9, and power supply 9 connects switch 8; Solenoid directional control valve 10 is two position-5 way valves.
A among Fig. 1, B point connect the air intake opening and the exhausr port of master cylinder 4, and R, the S residual air of naming a person for a particular job is discharged the atmosphere ventilating opening, and the P point is connected with source of the gas.
Its testing process is following:
Connect source of the gas, make the pressure of source of the gas up to standard through pressure regulator valve 2.Step on switch 8, energized 9 makes solenoid directional control valve 10 energisings, and the electromagnetic force that the solenoid of solenoid directional control valve 10 produces makes iron core overcome spring force and is raised, and PA, BS connect; This moment, air-flow moved through the piston that orders about master cylinder 4 from PA backward, is evacuated countercylinder 3 because solenoid directional control valve 10 is in conducting state.Rubber gauge head 6 is close to the air intake opening and the exhausr port of engine cylinder head 7 respectively at this moment, because gauge head 6 is processed for elastomeric material, has improved the sealing of fitting with engine cylinder head air intake opening and exhausr port; Through observing tensimeter 5, if comparing constantly with standard value, the numerical value of tensimeter 5 diminishes, then there is gas leak phenomenon; If it is constant that the numerical value of tensimeter 5 remains in the standard value range, then there is not the gas leakage situation.
After testing finishes, trip switch 8, power supply 9 makes solenoid directional control valve 10 outages, and the electromagnetic force of solenoid directional control valve 10 is disappeared, and iron core resets, and B, S break off, and cylinder stops to produce air-flow.
More than describing is the explanation to the utility model, is not the qualification to utility model, and the utility model institute restricted portion is referring to claim, and under the situation of the basic structure of the utility model, the utility model can be done any type of modification.
