  However, in the workpiece chucking device of Patent Document 1, when the electromagnetic valve is attached, the work of inserting the guide rod into the attachment hole of the electromagnetic valve and the two steps of temporary fixing and permanent fixing are performed. It took a lot of time to install, and time was lost.

  Moreover, according to the brake valve automatic test apparatus described in Patent Document 2, it is possible to reduce the labor of an operator who visually reads a pressure value or a change in a contact signal from a meter and records it manually. It is not possible to reduce the work and labor for installing the valve.

  Furthermore, according to the electromagnetic valve testing apparatus described in Patent Document 3, a leakage test of a plurality of electromagnetic valves attached to the mounting base can be performed at the same time, so that the test operation time can be shortened. And since it can respond by the common working fluid supply source with respect to the some solenoid valve attached to each mounting base, there exists an effect that the number of components can be reduced.

However, in general, in a valve body test apparatus that uses a compressible fluid such as air as a fluid, when measuring the response speed of the valve body under test, the valve body under test and the flow supplied to the valve body are measured. It is necessary to shorten the air passage between the valve body (pressure supply valve body) for turning on and off the pressure body as much as possible. That is, it is necessary to shorten the air passage in order to minimize the influence of the pressure transmission delay due to the compressibility of the fluid.
In addition, in order to test various valve bodies with the same test equipment, it is configured to install an adapter between the test equipment and the valve body to be tested. Is also easy.

  As described above, a plurality of pressure supply valve bodies that supply fluid pressure to the valve body are disposed in the vicinity of the mounting base to which the adapter is attached. Further, the pressure supply valve body is a fluid to the valve body to be tested. Since the size corresponding to the supply amount is required, the pressure supply valve body becomes larger when the valve body to be tested becomes larger. Therefore, the space for mounting the adapter on the mounting base is limited. It is difficult to screw the adapter to the test apparatus in such a narrow space, the work efficiency of the operator is lowered, and it takes time to prepare for the test.

  An object of the present invention is to provide a test apparatus for a valve body in which an adapter can be easily mounted on a mounting base in a space-saving manner.

On the lower surface of the mounting base 200, connection ports C2 corresponding to the plurality of pipes P11 and P12 are provided. A clamp lever 210 a and a clamp lever 210 b are provided on the other surface 202 side of the mounting base 200.

  As shown in FIG. 3, the mounting base 200 is moved in the direction of arrow F2 (vertically downward) to one end of the test base table 110 and attached to the test base table 110 (see FIG. 4).

  As shown in FIGS. 3 and 4, a pressure supply valve body 500 is provided on the other surface 202 side of the mounting table 200 and on the upper surface of the test table 110. 3 to 13, the pressure supply valve body 510 and the pressure supply valve body 520 of the pressure supply valve body 500 are illustrated.

In the pressure supply valve body 510 and the pressure supply valve body 520, a plurality of pipes P1 and P2 are arranged so as to circulate in the pressure supply valve bodies 510 and 520. On-off valves 511 are provided on the pipes P1, P2 in the pressure supply valve body 510, and on-off valves 521 are provided on the pipes P1, P2 in the pressure supply valve body 520.
By opening / closing the on-off valve 511 and the on-off valve 521, air from the air source is supplied into the plurality of pipes P1, P2. Specifically, as the on-off valves 511 and 521, a direct-acting small solenoid valve or the like can be used for the small flow circuit, and a pilot solenoid valve type membrane plate on-off valve can be used for the large flow circuit.

  Subsequently, as illustrated in FIG. 5, the adapter 300 is attached in the direction of arrow F <b> 3 (horizontal direction) from the one surface 201 side of the mounting base 200. In this case, the clamp levers 210a and 210b are arranged at positions that do not hinder the mounting base connecting members 340a and 340b from moving in the direction of the arrow F3.

  Here, when the limit switches S1a and S2a do not detect the clamp levers 210a and 210b, the open / close valve 511 and the open / close valve 521 are closed, or the supply of air from the air compressor of the air source is controlled. 102 to stop. Thereby, it is possible to prevent the supply of air from starting until the adapter 300 is securely attached to the mounting base 200. In addition, when it is made to detect that the valve body 400 is attached with another sensor, the output from this other sensor is also used, and it is controlled by the control box 102 until both detections are turned ON. The on-off valve 511 and the on-off valve 521 may not be opened, or the supply of air from the air source may not be started. If the limit switches S1a and S2a stop detecting after supplying air, the control valve 102 stops the supply of air from the air compressor of the air source by closing the on-off valve 511 and the on-off valve 521. You may do it. With this configuration, the safety of the test work can be ensured.

  Now, the mounting base connecting members 340 a and 340 b of the adapter 300 are fitted with the clamp levers 210 a and 210 b of the mounting base 200, and the adapter 300 is supported by the mounting base 200. As a result, the adapter 300 can be prevented from falling.
