Description

[0001] Apparatus For Testing Gas Leakage Can Be Portable [

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a test apparatus for leakage test, and more particularly, to a rechargeable portable leak test apparatus for testing leakage of various vacuum equipment used in a semiconductor, LCD, LED, or SOLAR manufacturing facility.

Vacuum equipment is installed in semiconductor, LCD, LED or SOLAR manufacturing facilities. These vacuum equipments are used for various purposes and should be operated in vacuum condition. Therefore, the degree of vacuum is an important factor in determining the quality or defect of the product. Therefore, periodic care should be taken to prevent leakage from any part of the vacuum system. If a leak is found, it must be recovered.

In this way, it is being carried out to check whether or not the vacuum is leaked from various vacuum equipment or to locate the leakage point. The test gas is used for this operation. That is, when the test gas is sprayed to the leaked portion, the test gas will flow into the vacuum facility, and the test gas can be detected by the gas detector inside the equipment. That is, if the test gas is detected, there is a leak.

As the test gas, helium (He) gas having a small particle size and stable molecular structure is used. Helium has been widely used because it has a stable structure and a small particle size, which can be introduced through fine gaps and can increase detection accuracy.

For the test using helium, conventionally, piping for only helium gas was installed inside the plant, and helium was taken out from the plant for testing. In this case, since the helium pipe must be installed as a whole, there is a problem that the cost is excessively increased.

To solve this problem, a helium gas cylinder filled with helium was installed on a cart or a bogie to carry out a leak test by going around the facility. In this case, the helium gas cylinder used is large in size and difficult to transport and obstructs the existing operator. In order to test a narrow area or a high point, a long hose must be connected and used.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. First, basic matters will be described with reference to FIGS. 1 to 6, and the following description will be given with reference to the remaining drawings.

The portable leak test instrument according to the present invention has a configuration in which the test gas is charged into the pressure-resistant container (B) at a high pressure and is drawn out at a moment to be tested. Therefore, it is easy for the operator to carry it personally, and the pressure-resistant container may have a capacity of 50 to 300 cc, for example, and may be made of metal such as aluminum. The charging pressure of the test gas depends on various conditions.

In the pressure-resistant vessel B, a thread is provided in the injection port, and the inner valve 100 is fastened to the injection port. On the upper surface of the inner valve, a pin 121 (see Figs. 7 to 10) protrudes. When this pin 121 is pushed, the test gas is ejected through the pin-fitted hole. The inner valve 100 will be described later. Hereinafter, the valve opening 1 for discharging the test gas by operating the inner valve 100 will be described first.

The valve opening portion 1 is operated to open the inner valve 100 so that the test gas is ejected by a small amount in a reduced pressure state through the gas outlet 47 of the orifice type. The valve opening portion 1 includes a casing 3 which is coupled to the inner valve 100 to be installed on the pressure-resistant container B; A presser bar (21) which presses the pin (121) projecting from the upper surface of the inner valve (100) upwardly and upwardly while being installed in the casing (3); And a push switch 33 installed at the upper end of the casing 3 so as to press the presser bar 21 from above. When the presser 21 presses the pin 121 and presses it, the test gas ejected from the pressure-resistant container B is ejected only through the gas outlet 47 provided on the side of the casing 3, And a gas guide means provided in the gas passage. On the outer surface of the casing (3), a catching part (3a) can be provided so as to be convenient to hold by hand.

The presser bar 21 is installed such that it can be vertically maneuvered while keeping the airtight state in a state of being fitted inside the cylinder 20 provided in the longitudinal direction inside the casing 3 like a piston. Tight packing (21, 25) is fitted on the outer circumferential surface of the presser bar (21). A push pin 15 protrudes downward from the push rod 21 and extends toward the pin 121 of the inner valve after passing through the pin guide hole 19. A pin guide hole (19) penetrating through the pressing pin (15) penetrates the lower end of the cylinder to prevent the pressing pin (15) from flowing.

On the other hand, a sealing member 11 is provided at the boundary between the inner valve 100 and the casing. A center hole 13 is formed at the center of the sealing member 11 in which the pressing pin 15 is inserted. An O-ring 17 is fitted to the edge of the center hole 13 to maintain airtightness.

According to the feature of the present invention, since the spring 43 is interposed between the presser bar 21 and the push switch 33, the push switch 33 is forced to return to the original position by the elastic force of the spring 43. A spring seat 45 is provided at the upper portion of the presser bar.

The push switch 33 is fitted to the switch seating portion 73 provided at the upper end of the casing 3. A pinhole 79 provided at one upper end 37 of the casing is provided and the push switch 33 is fitted in a hinge pin 65 which engages with the pinhole 79. The hinge pin (65) is fitted in the pin coupling groove (31) provided at one side of the push switch (33). Therefore, the push switch 33 performs a seesaw motion in a certain range about the hinge pin 65. [

A connector 41 may be interposed between the spring 43 and the push switch 33. The connector (41) is installed so as to be vertically movable in a state of being fitted in the cylinder (20). A push rod 35 protrudes upward from the connecting port 41 and is supported by the push switch bottom face 33b. When the upper surface 33a of the push switch is manually pressed, the test gas is ejected to the outside along the direction of the arrow with a thick solid line in Fig.

According to still another aspect of the present invention, a gas (flow rate) regulator for regulating the amount of test gas to be blown by limiting the starting range of the push switch 33 is further included.

The gas control member includes an adjusting pin 27, an adjusting switch 29, and an adjusting pin guide 30. The casing 3 is provided with an adjustment pin installation space 75 for allowing the adjustment pin 27 to move and flow. One end of the adjustment pin 27 is screwed into a screw groove 77 provided in the adjustment pin installation space 75 of the casing and the upper end 31 is selectively supported on the bottom surface 33b of the push switch. The adjustment switch 29 is for restricting the degree to which the adjustment pin 27 is screwed to the casing 3 by rotating the adjustment pin 27 and may be integrally formed with the adjustment pin 27.

The adjustment pin guide 30 is fitted to the upper end of the adjustment pin 27 to guide the adjustment pin 27 to start up and down.

The adjustment switch 29 is adapted to be manually turned by the user. Therefore, as the adjustment pin 27 is farther away from the bottom surface 33b of the push switch, the ejection amount increases, and as the ejection amount decreases, the ejection amount decreases. Therefore, the ejection amount of the test gas can be freely adjusted within a certain range, and it is possible to prevent the ejection amount of the test gas from being excessively ejected due to the error. In practice, such a gas (flow rate) regulating mechanism becomes useful because it is possible to barely eject a gas to such an extent that the gas can barely be judged by the touch.

According to another aspect of the present invention, the apparatus further includes an induction pipe coupling body (53) coupled to the gas outlet (47) so as to eject the test gas precisely at a local point.

The induction pipe assembly 53 is screwed to the casing 3 and has a socket 63 provided with pinholes 67 on both sides thereof and a socket 63 which is coupled to the pinhole 67 of the socket and is rotatable about the pinhole 67 And a jetting pipe 59 extending to the distal end of the rotary shaft 69 and extending long. At the rear end of the socket 63, there is provided a coupling portion 61 screwed into a screw hole extending from the gas outlet 47 of the casing, and a hinge coupling hole 67 for hinge coupling of the rotary shaft is provided at both sides . A groove into which the rotation hole 69 can be fitted is provided toward the front of the socket 63. [ The rotary tool 69 includes a cylindrical socket engaging hole 69 which engages with the socket 63 and a spray pipe coupling 55 to which the spray pipe 59 is coupled. On both sides of the socket coupling hole (69), a projection (71) fitted to the hinge coupling hole (67) is protruded.

Between the casing (3) and the socket (63) and between the socket (63) and the rotary tool (69), packing (49, 51) for hermetic sealing is provided. The rotary tool 69 can be rotated in a predetermined angular range around the projection 71 as an axis. This configuration freely adjusts the injecting direction of the test gas so that the test gas can be injected at the correct position. At one end of the spray tube 59, a screw coupling portion 57 for coupling with the rotary shaft is provided. The spray tube 59 is a thin tubular body having an inner diameter of 1 to 3 mm, and may be replaced with a different length if necessary.

Hereinafter, the inner valve 100, which has been briefly described above, will be described with reference to FIGS. 7 to 10. FIG.

The body of the valve mechanism is integrally formed to maintain rigidity.

In order to engage the valve opening described above, a male screw portion 105 is provided on the outer circumferential surface of one side of the body. A first female screw portion 107 is provided on the inner circumferential surface of the other side of the body 1 in order to engage the container body B. [

A first sealing seating portion 111 is provided adjacent to the first internal thread portion 107 where the first sealing member 109 is inserted. A cylindrical valve operating chamber 113 is provided inside the body. The valve operating chamber 113 is connected to the first sealing seating portion 111 and has an inner diameter smaller than the inner diameter of the first sealing seating portion 111. A pin hole 115 is provided at one side of the body so that the valve operating chamber 113 can communicate with the outside air. The pinhole 115 is provided at the center of the contact surface 103.

The valve body 117 is fitted into the valve operating chamber 113 to open and close the pinhole 115. [ The valve body 117 has a button-shaped head 119 fitted in the valve operating chamber 113 and installed so as to be movable upward and downward in the drawing, And a pin 121 formed thereon. The fin 121 may have a conical column shape by narrowing the cross-sectional area toward the end.

According to another embodiment of the present invention, the head 119 of the valve body has a stepped portion composed of a large-diameter portion 119a and a small-diameter portion 119b. The upper surface of the head 119, that is, the surface 127, which is in contact with the second sealing member 125 described later, is an inclined surface.

The stopper member 127 is corked to the rear end of the valve operating chamber 113 to reduce the cross sectional area of the valve operating chamber 113. [ The stopper member 129 is screwed to the second female threaded portion 131 provided on the inner circumferential surface of the valve operating chamber 113 as shown in FIG. A gate hole 133 should be provided in the middle of the stopper member 129 so that the gas can pass therethrough. The gate hole 133 is provided so as to have a diameter similar to that of the pinhole 113. In addition, a tool groove 135 is provided on one side of the stopper member 129, which can be rotated using a tool such as a screwdriver or a wrench.

The coil spring 137 is fitted in the valve operating chamber 113 so that one end is supported on the bottom surface of the head 119 of the valve body and the other end is supported on the upper surface of the stopper member 129. The annular second sealing member 125 is fitted in the valve operating chamber 113 so that one end of the annular second sealing member 125 is supported by the tip wall 139 provided with the pinhole 115 and the other end is supported by the head 119 of the valve body. An embossing 143 is formed on the bottom surface of the second sealing member 125 which is in contact with the head 119.

On the other hand, in the case of a gas composed of small particles such as helium (He), more careful attention to leakage is required. In the previous embodiment, there is also a possibility that the second sealing member 125 is opened due to the pressure applied on the top of the valve body when the gas is charged, and the valve body 117 is disengaged.

The head 119 of the valve body 117 is in the form of a cup having an open top. The head 119 of the valve body 117 includes a bottom plate 155 and a cylindrical side wall 151 provided at the edge of the bottom plate 155 to provide an upper open seating space 153 and a bottom plate 155 And a pin 121 protruding from the center. The second sealing member 125 is fitted into the seating space 153 provided by the valve body 117. The height of the side wall 151 is higher than the height of the second sealing member 125 so that the second sealing member 125 can not escape from the seating space 153 of the head 119 even if the shape of the second sealing member 125 changes.

A presser bar (157) is integrally protruded toward the second sealing member (125) at the center of the front end wall (139) of the body. The pressure pad 157 has a cylindrical shape and the tip end face 159 is inclined to approach the second sealing member 125 toward the center. The angle M between the horizontal plane and the front end face 159 may be 60 to 80 degrees. This is a method for further increasing the airtightness holding force by allowing the pressure pad 157 to press the upper surface of the second sealing member 125 in a manner similar to a wedge.

The presser bar 157 also has an outer diameter that can be closely fitted into the side wall 151 of the head 119 of the valve body. This is also a means to further tighten the confidentiality.

The inner valve 100 according to the present embodiment is advantageous in that the second sealing member 125 is secure from the deformation due to the high temperature of the compressed gas when the gas is charged so that the durability is good and the charging is facilitated.

The configuration shown and described above is merely a preferred embodiment based on the technical idea of the present invention. It will be understood by those skilled in the art that various changes and modifications may be made without departing from the scope of the present invention.
