DETAILED DESCRIPTION

[0023] In order to better understand the purpose, structure and function of the utility model, the pressure testing device applied to the integrated valve seat of the formation testing instrument of the utility model will be further described in detail below in combination with the drawings.

[0024] As shown in Figure 1 , Figure 2 , Figure 3 , it shows the pressure testing device 2 applied to the integrated valve seat 1 of the formation testing instrument of the utility model embodiment, which comprises a pressure testing device body 21, the pressure testing device body 21 is provided with an input oil way connecting hole 26, one end of the input oil way connecting hole 26 is used for being connected with the oil injection machine 4, and the other end of the input oil way connecting hole 26 is used for being connected with the input interface of the valve seat body.

[0025] The pressure testing device body 21 is provided with a detection interface 24 and a plurality of output oil way connecting holes 27, one end of each output oil way connecting hole 27 is respectively used for being connected with one output interface of the valve seat body of the integrated valve seat 1, the other end of all the output oil way connecting holes 27 is connected to the detection interface 24, and the detection interface 24 is used for being connected with the detection equipment 3.

[0026] The pressure testing device body 21 is provided with an oil return connecting hole 28, one end of the oil return connecting hole 28 is used for being connected with the oil return interface 23 of the valve seat body, and the other end of the oil return connecting hole 28 is used for being connected with the oil injection machine 4.

[0027] The pressing base 2 of the embodiment comprises a pressing base body 21. Firstly, the pressing base body 21 is provided with an input oil path connecting hole 26. When the electromagnetic valve is tested, one end of the input oil path connecting hole 26 is connected with an oil supply device such as an oil injection machine 4 or an oil injection vehicle, and the other end of the input oil path connecting hole 26 is connected with an input interface of the valve seat body. Therefore, hydraulic oil in the oil supply device such as the oil injection machine 4 or the oil injection vehicle can flow into the input interface of the valve seat body through the input oil path connecting hole 26, and then flow into the inlet of the electromagnetic valve of the valve seat body through the input interface of the valve seat body.

[0028] Secondly, the pressing base body 21 is further provided with an oil return connecting hole 28, a detection interface 24 and a plurality of output oil path connecting holes 27. Taking a two-position three-way electromagnetic valve as an example, the input port and the output port of the electromagnetic valve are not connected in normal state, and the input port and the oil return port are connected. When the electromagnetic valve is tested by pressing, the hydraulic oil flowing into the inlet of the electromagnetic valve of the valve seat body flows out from the oil return connecting hole 28 in normal state. At this time, the hydraulic oil does not pass through the detection interface 24, so the detection device 3 at the detection interface 24 should not detect the hydraulic oil. When the input port and the output port of the electromagnetic valve are connected by the power supply, the hydraulic oil flowing into the inlet of the electromagnetic valve of the valve seat body flows out from the outlet of the electromagnetic valve at this time. The hydraulic oil flowing out from the outlet of the electromagnetic valve flows into the detection interface 24 in turn through the corresponding output interface of the valve seat body and the corresponding output oil path connecting hole 27 on the pressing base body 21. At this time, the detection device 3 at the detection interface 24 should detect the hydraulic oil. Accordingly, whether the function of the electromagnetic valve is normal can be judged by the detection device 3 at the detection interface 24, that is, whether the function of the electromagnetic valve in normal state is normal and whether the electromagnetic valve can be switched to another state can be judged.

[0029] The number of output oil path connecting holes 27 of the embodiment is a plurality, so that the electromagnetic valves on various valve seat bodies with the number of output interfaces less than the number of output oil path connecting holes 27 of the embodiment can be tested by pressing.

[0030] When the function of the electromagnetic valve of the integrated valve seat 1 of the formation testing instrument is tested by using the pressing base 2 of the embodiment, after the pressing base body 21 and the corresponding interfaces on the valve seat body of the integrated valve seat 1 are connected, only one end of the input oil path connecting hole 26 is connected with the oil injection machine 4, the detection interface 24 is connected with the detection device 3, and the other end of the oil return connecting hole 28 is connected with the oil injection machine 4. That is, only one oil injection machine 4 and one detection device 3 in the outside world are needed after the pressing base 2 of the embodiment is used. Therefore, the task of testing each electromagnetic valve of the integrated valve seat 1 by pressing can be completed at one time, and the problem that a plurality of detection devices 3 or a plurality of oil injection machines 4 are needed in the prior art is solved.

[0031] The one end of the input oil path connecting hole 26 is provided with a press interface 22 for connecting with the oil injection machine 4.

[0034] The power line through hole 25 of the embodiment is used for the power line to pass through, so as to facilitate the connection of the power interface of the valve seat body with the test power source 6 during the press test.

[0035] The utility model embodiment further provides a press test device applied to the integrated valve seat 1 of the formation testing instrument, as shown in the figure, Figure 3 The one end of the input oil path connecting hole 26 and the other end of the oil return connecting hole 28 are connected with the oil injection machine 4, and the detection interface 24 is connected with the detection equipment 3.

[0036] When the press test device is applied to the press test of the electromagnetic valve on the valve seat body, the corresponding interfaces on the press base body 21 and the valve seat body are connected, the one end of the input oil path connecting hole 26 and the other end of the oil return connecting hole 28 are connected with the oil injection machine 4, and the detection interface 24 is connected with the detection equipment 3. When the press test is specifically performed, taking a two-position three-way electromagnetic valve as an example, the input port and the output port of the electromagnetic valve are set to be not connected in the normal state, and the input port and the oil return port are connected, so that when the press test of the electromagnetic valve is performed, the hydraulic oil flowing into the inlet of the electromagnetic valve on the valve seat body flows out from the oil return connecting hole 28 in the normal state, at this time, the hydraulic oil does not pass through the detection interface 24, so the detection equipment 3 at the detection interface 24 should not detect the hydraulic oil, so as to judge whether the state of the electromagnetic valve in the normal state is correct; when the input port and the output port of the electromagnetic valve are connected through the power supply, at this time, the hydraulic oil flowing into the inlet of the electromagnetic valve on the valve seat body flows out from the outlet of the electromagnetic valve, and the hydraulic oil flowing out from the outlet of the electromagnetic valve flows into the detection interface 24 through the corresponding output oil path connecting hole 27 on the valve seat body and the corresponding output oil path connecting hole 27 on the press base body 21 in turn, at this time, the detection equipment 3 at the detection interface 24 should detect the hydraulic oil, so as to judge whether the electromagnetic valve can be switched to the corresponding state after being powered on.

[0037] The other end of the input oil path connecting hole 26 is connected with the input interface of the valve seat body through a connecting pipe 5, and the two ends of the connecting pipe 5 should also be sealed.

[0038] Wherein, one end of each output oil way connecting hole 27 is connected with the corresponding output interface of the valve seat body through the connecting pipe 5, and the both ends of the connecting pipe 5 should also be sealed.

[0039] Wherein, one end of the oil return connecting hole 28 is connected with the oil return interface 23 of the valve seat body through the connecting pipe 5, and the both ends of the connecting pipe 5 should also be sealed.

[0040] Wherein, the detection device 3 is a pressure gauge, so that whether there is oil at the detection interface 24 can be judged by whether the pressure gauge has pressure indication.

[0041] Wherein, the electromagnetic valve on the valve seat body is connected with the power line, and the power line is connected with the test power source 6 through the power line through hole 25 on the pressure base body 21.
