The present invention relates to an external leak tester of an IC fan heater solenoid valve for inspecting leakage of air or oil from the solenoid valve for an IC fan heater to the outside.

In the solenoid valve, when measuring leakage from the inside to the outside, it is recognized that it can be used only when there is no leakage when applying an airtight pressure of 3 kg / cm2. It was complicated and cumbersome to use, and it was impossible to maintain complete air tightness at the upper and lower connections and valve contacts of the fuselage during testing.

Accordingly, the present invention has been made in view of the above-mentioned drawbacks of the prior art to provide an external leakage test apparatus for a solenoid valve for an IC fan heater which has a simple structure which eliminates malfunction during testing and makes the test work very simple. When described in detail based on the accompanying drawings as follows.

On the supporting plate (1), a leakage preventing packing (2) is installed on the upper edge of the upper surface, and an airtight leakage preventing packing (5) is installed on the upper edge of the upper case in the lower case (4) in which the pressure chamber (3) is formed inside. The tip actuating pin 7 of the solenoid valve 6 forms a hole 8 for insertion, and the nipple 10 in the air supply hole 9 and the air supply hole 9 to one side of the hole 8. The fixing rods 11 were screwed together to be inserted and fixed, so that the stepped portion 12 was mounted on the airtight leakage preventing ring 13 inserted and fixed to the lower case 4 on the upper portion of the fixing rods 11, Also, an insertion tube in which the holes 14 and 14 'are drilled so that the support plate 1 and the lower case 4 abut, and the air discharge pipe 15 is screwed into the holes 14 and 14'. 16) is inserted into the upper surface of the lower case (4) in the upper surface to be opened and closed around the hinge (18) on the upper support plate 17 fixed to the back of the support plate (1). "With a further 19 and to the lower lid 20

Figure kpo00002
"One end of the support section 21 of the type, but the front of the support section 21 was installed a handle 23 operated by the spring 22, the spring 22 is a spring made of a separate component The handle 24 is inserted into the inside of the cap 24 by the cap 24, and the handle 23 forms a ruled bar 25 at the end and a spring tangydol piece 26 at the inside thereof, and coincides with the ruled bar 25. It is an external leakage test apparatus of the solenoid valve for the IC fan heater configured by forming the ruled bar 27 in the lower case 4 to be used.

Reference numeral 31 is a hose, 32 is a water tank, 33 is a fixing bolt, 34 is a packing, 35 is a piston rod, 36 is a support.

Referring to the operation and effects of the present invention configured as described above are as follows.

First, before attaching the solenoid valve to the apparatus of the present invention, the air is supplied from the air compressor to the unit of the apparatus, and the pressure is set at 5-6 kg / cm 2, and then the handle ( 23) by pulling forward the ruled bar 25, which is defined in the guide groove 27, is pulled out of the guide groove 27, and then lifted upward.

Figure kpo00003
&Quot; Type support section 21 is opened centering on hinge 18, in which pressure chamber 3 is inserted with end operating plate 7 of solenoid valve 6 to be tested inserted into hole 8; ) Into the pressure chamber (3),
Figure kpo00004
"Down the support section 21 is lowered as a handle 23 installed in the tip end to be ruled, and when pulled the handle 23 forward in the same manner as when open, spring 22 inserted into the cap 24 ) Is compressed by the tungsten stone piece 26 and when the jingjung bar 25 passes through the outer circumferential surface of the lower case 4 and releases the handle 23 that is pulled when reaching the jungjeong groove 27, the spring of the spring 22 The ruled bar (25) is inserted into the free groove (27) by the force,
Figure kpo00005
"The mold support is fixed, and in this state, the cylinder 19 is operated as a switch to cover the lower case 4 firmly as the lid 20 installed at the end of the piston rod 35 is lowered. The airtight leakage preventing packing 5 of the upper periphery of the case 4 prevents air from leaking into the pressure chamber 3 during the test.

Therefore, in the above state, the pressure of 5-6kg / ㎠ set through the air supply hole 9 is injected into the pressure chamber 3 at a uniform pressure of 3kg / ㎠ through the regulator. If there is no reaction in the water tank 32 even after elapsed, there is no problem. If the water tank is bad, the pressure in the pressure chamber is discharged to the air discharge pipe 9 through the inside of the solenoid valve 6, and the water tank through the hose 31. This can be seen by causing bubble generation in (32).

When the external leakage test of the solenoid valve is completed as above, shut off the regulator by stopping the air supply, move the cylinder (19) to raise the lid (20), and pull out the handle (23).

Figure kpo00006
It is sufficient to raise the mold support section 21 and pull out the solenoid valve 6.

As described above, the present invention has the advantage that the external leakage test of the solenoid valve is extremely simple, with a simple configuration and almost no malfunction in the test, so that even a beginner can easily use the device. Multiple installations allow testing of many solenoid valves at the same time.
