Abstract

PURPOSE:To facilitate escape of an internal fluid at the time of a sealing performance test by providing a seal surface between an apparatus body to be sealed and a cover member with a continuity groove for connecting the outside and inside of the apparatus. CONSTITUTION:An apparatus body 11 includes an opening 11a to be sealed, the periphery of which is provided with a cover member 12 secured thereto. A contact surface of the cover member 12 with the apparatus body 11 is provided with a line groove 12a for positioning a seal member 13 and with one fluid continuity groove 14 for connecting the inside and the outside of the apparatus body 11.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the structure of sealed equipment, particularly to a structure that can reliably detect deficiencies in the assembly of pneumatic and hydraulic equipment.

The conventional structure of this type of secret sword equipment is, for example, Ill.
/WAK 4 is shown in the figure. ◎ In the figure, l indicates the machine/main body, C indicates the cover material, and J indicates the bolts that secure the cover member to the horizontal body.

Here, the bud member λ is set in advance with the 0 ring lft as a tar member on the endless column, and this main member is used to close the main body of the device. Part I11 will be in contact with the main body of the device around the opening/field, so after positioning Part I1 with respect to the main body of the device, tighten bolt 3 and seal. ◇ However, with such conventional technology, due to the remarkable improvement in machining technology in recent years, for example, the assembling of the seal member is forgotten, the damaged seal member is reattached for a few seconds, and the seal member is Even if foreign matter gets caught in the seal, it is difficult to reliably detect these defects in a relatively short sealing performance test, and air leaks or oil leaks that occur later may be caused by, for example, Because of the risk of causing a vehicle accident, it was necessary to spend many man-hours on the inspection.

The present invention provides a structure for a sealed device that sufficiently eliminates the above-mentioned drawbacks of the prior art. By providing a conduction groove on at least one side of the device that conducts the inside and outside of the device, and making it easier to prevent leakage of internal fluid during sealing performance inspection, complete discovery of each of the above defects can be accomplished with less man-hours. The following is an explanation of what makes this possible, based on the drawings.

FIG. 1 shows an embodiment of the present invention containing water.

In the figure, l/ indicates the device body, and this device body has an opening //a that can be sealed. /J indicates a lid member.

This lid member /J is fixed around the opening of the device body //, while the lid member /J is in contact with the device body // for 1 m! IiK, O having a groove/Ja for positioning the seal member/Jt
In this example, as is clear from Figure 2(b),
A single fluid communication groove is provided that communicates the inside and outside of the lid member/JK1 device body//. In addition, Figure J 6) Medium/Jb
is almost circular! - Three locations Kll in the circumferential direction of eggplant lid member/J
/Jc indicates these flanges/
Jb The fluid conduction groove 1 in Oζ, which indicates the bolt hole provided in K, is used when, for example, the seal member /J is forgotten to be inserted after the device body is sealed as shown in Fig. 1 (,). While communicating between the inside and outside of the device body //,
If a seal member/J is installed, it must be provided to prevent communication.
/Ja seconds also contains a shallow depth. Note that the seal member 13
In addition to the 0 ring, there are 14 square ring gaskets, etc.
Of course, it can be used.

The sealing of the opening //m in this example is the same as that described above with reference to FIG. //Close the a, and then close the device body of the lid member l.//
Perform positioning for.

This is achieved by tightening the bolt inserted into the bolt hole/Jc.

In the sealing performance inspection after assembly, if the proper seal member/J is installed without any defects, the action of the seal member/J will prevent leakage of fluid inside the device passing through the fluid conduction groove/4/Lt. While fluid leakage is reliably prevented, if, for example, the seal member 13 is forgotten to be installed, leakage of fluid inside the device can be immediately and reliably detected. If a foreign object gets caught in a member, the fluid that leaks from the cut or the part where the foreign object gets caught should be treated as
Since the fluid flows out of the main body of the device through the fluid conduction groove l#, malfunctions in this case can be detected reliably.

Although this invention has been described above based on the illustrated example, it is possible to provide a plurality of fluid conducting groove tubes or a fluid conducting groove on the device main body side.
At least four fluid-conducting grooves are provided on at least one side of the s-plane, extending both inward and outward directions of the device body. If there are any defects in the assembly, deficiencies, or other defects in pressure and hydraulic equipment,
1.It is possible to quickly and completely attack what is discovered through a seal performance test and reliably prevent subsequent leakage of internal fluid.
