[0002] The valve block is used in an electro-hydraulic servo control system. In the TRT device, it belongs to a subsystem of one of the eight major systems. The valve block is a complex functional block that installs various hydraulic components and can achieve the interconnection of components according to the internal channels. It is a key component in the hydraulic transmission system. After the valve block is manufactured, it needs to be subjected to an airtightness test to avoid leakage after assembly.

[0003] The existing valve block testing equipment generally tests by pressurizing the valve block and checking whether the air pressure in the valve block drops after a period of time. This method has a long waiting time and low testing efficiency.

[0004] Therefore, in order to solve the above problems, it is necessary to design a testing equipment for valve blocks. Content of the Utility Model

[0005] The purpose of the utility model is to provide a testing equipment for valve blocks to solve the technical problem of low testing efficiency of the existing testing equipment.

[0007] A water tank and a hollow plate and a support plate sequentially arranged above the water tank; wherein

[0008] A plurality of connecting columns are arranged between the hollow plate and the support plate;

[0009] A bottom sealing plate is arranged on the hollow plate;

[0010] A top sealing plate is arranged below the support plate; wherein

[0011] The bottom sealing plate and the top sealing plate are suitable for sealing the valve block holes;

[0012] First telescopic members arranged on both sides of the water tank, and their telescopic ends are connected to the support plate;

[0013] The first telescopic members are suitable for driving the support plate, the connecting columns and the hollow plate to move downward when retracting, so that the bottom sealing plate, the valve block and the top sealing plate on the hollow plate are immersed in the water in the water tank;

[0014] A conical air nozzle arranged at the bottom of the top sealing plate, which is suitable for supplying air to the immersed valve block.

[0015] Further, a second telescopic member is arranged at the top of the support plate; wherein

[0016] A connecting plate is provided on the top of the top sealing plate;

[0017] The telescopic end of the second telescopic member is connected to the connecting plate; and

[0018] The second telescopic member is adapted to drive the top sealing plate to move downward and press the valve block through the connecting plate, so that the top sealing plate and the bottom sealing plate seal the valve block hole.

[0019] Furthermore, at least two guide sleeves are embedded on the support plate;

[0020] At least two guide posts are provided on the top of the connecting plate; among which

[0021] Each of the guide posts is adapted to slide in the corresponding guide sleeve.

[0022] Furthermore, four guide rails are provided on the hollow plate;

[0023] Each of the guide rails is arranged on the side of the corresponding bottom sealing plate;

[0030] Furthermore, a number of sealing protrusions are provided on the top sealing plate, the bottom sealing plate and the side sealing plate; among which

[0031] Each of the sealing protrusions is adapted to block the valve block hole.

[0032] Furthermore, a limiting block is provided above one end of the guide rail; among which

[0033] The limiting block is located at one end away from the bottom sealing plate.

[0034] The beneficial effects of the utility model are:

[0035] (1). In the present utility model, the water tank is filled with water, and the valve block is placed on the bottom sealing plate of the base plate. By controlling the second telescopic member to extend, the second telescopic member drives the top sealing plate to move downward through the connecting plate and presses down on the valve block, so that the top sealing plate and the bottom sealing plate fully seal the valve block holes. At the same time, the conical air nozzle is inserted into any one of the valve block holes, and the first telescopic member is controlled to retract.

At this time, air is supplied into the valve block hole through the conical air nozzle, and it is observed whether there are bubbles emerging in the water tank, thereby achieving the effects of intuitive, convenient, and fast testing.

[0036] (2). In the present utility model, the valve block is placed on the bottom sealing plate, and the sealing protrusions on the bottom sealing plate position the valve block. At this time, the second telescopic member is controlled to extend, and the top sealing plate is driven to move downward through the connecting plate and presses down on the valve block. The sealing protrusions on the top sealing plate seal the top holes of the valve block. The guide posts slide downward in the guide sleeves. At the same time, the inclined rods are inserted into the inclined holes when moving downward, so that the push blocks slide on the guide rails, so that the sealing protrusions on each side sealing plate seal the side holes of the valve block. When the second telescopic member retracts, the top sealing plate and the sealing protrusions on the top sealing plate are separated from the valve block. At the same time, the inclined rods move upward through the inclined holes to make the push blocks slide on the guide rails, so that the side sealing plates and the sealing protrusions on the side sealing plates are separated from the valve block. Through the above steps, the effects of rapid sealing and rapid unsealing are achieved, thereby reducing the testing time.
