Description

Technical Field

[0001] The utility model relates to a testing device for valve parts, in particular to a testing device for a reducing casting short pipe. Background Art

[0002] The cast iron short pipe for valves is a fitting used to connect and install valves. Its main function is to change the pipeline joint mode, making the socket and spigot of ductile iron pipes become flange ports, so as to dock with gate valves or butterfly valves, etc. The cast iron short pipes for valves, usually called "short pipe A" and "short pipe B", are pipeline connectors with special designs. Short pipe A refers to a cast iron short pipe with a socket at one end and a flange at the other end; while short pipe B refers to a cast iron short pipe with a spigot at one end and a flange at the other end. This design is mainly to solve the problem that cast iron pipes cannot be threaded or welded like steel pipes during connection. By using cast iron short pipes with sockets and spigots, it is convenient to connect cast iron pipes with various valves (such as gate valves, butterfly valves, etc.). A reducing short pipe, also known as a reducing pipe or a tapered pipe, is a pipeline element used to connect two straight pipes with different diameters. The reducing short pipe is mainly used to connect pipes with different diameters, and by changing the flow rate or direction of the fluid, it can adapt to different process requirements or space limitations.

[0003] At present, due to the special structure of the reducing short pipe, the pressure resistance test can only be manually operated, which is inconvenient to operate, has great danger, and can only be carried out at one angle for the pressure resistance test. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is that the existing reducing short pipe cannot be tested at multiple angles and cannot be automatically tested. Therefore, a testing device for a multi-angle reducing casting short pipe is provided.

[0005] The technical solution of the utility model is: a testing device for a multi-angle reducing casting short pipe, including: a rectangular frame, which is arranged perpendicular to the ground; a card slot, which is opened at the center of the lower surface inside the rectangular frame; a Y-axis slider, which is slidably installed on both side walls inside the rectangular frame; a Y-axis cylinder, which is installed on the upper surface outside the rectangular frame and is in transmission connection with the Y-axis slider; an X-axis cylinder, which is installed on the Y-axis slider, and the piston rod of the X-axis cylinder faces the center of the rectangular frame; a vertical pressing plate, which is fixedly connected to the piston rod of the X-axis cylinder; a Z-axis cylinder, which is installed at the center of the upper surface outside the rectangular frame; and a horizontal pressing plate, which is in transmission connection with the Z-axis cylinder and is directly opposite to the card slot.

[0006] The improvement of the above solution is that an extended base is arranged outside the rectangular frame, an auxiliary cylinder extending towards the card slot is fixedly connected to the extended base, and an auxiliary vertical pressing plate is fixedly connected to the piston rod of the auxiliary cylinder.

[0007] A further improvement of the above solution is that the card slot includes a retaining dam, both sides of the top of the retaining dam have horizontal segments extending inwards, the ends of the horizontal segments are hinged with side baffles, and linear drive mechanisms extending into the retaining dam are installed on both sides of the retaining dam, and the linear drive mechanisms are in contact with the side baffles.

[0008] In the above solution, the linear drive mechanism is a cylinder, and the piston rod of the cylinder is in contact with the side baffle.

[0009] A further improvement of the above solution is that the rectangular frame extends outwards with a transfer table, and one end of the transfer table is adjacent to the card slot.

[0010] In the above solution, a conveyor belt is installed on the surface of the transfer table.

[0011] The beneficial effect of the present utility model is that multiple vertical pressing plates and horizontal pressing plates are used to perform multi-angle pressure tests on the reducing short pipe. The reducing short pipe is placed in the card slot to prevent it from shaking. Description of the Drawings

Detailed Embodiment

[0016] The following further describes the present invention with reference to the drawings.

[0017] As Figure 1As shown in the figure, a multi-angle reducing casting short pipe testing device includes: a rectangular frame 1, which is vertically arranged with respect to the ground; a card slot 2, which is opened at the center of the lower surface inside the rectangular frame; a Y-axis slider 3, which is slidably installed on both side walls inside the rectangular frame; a Y-axis cylinder 4, which is installed on the upper surface outside the rectangular frame and is in driving connection with the Y-axis slider; an X-axis cylinder 5, which is installed on the Y-axis slider, and the piston rod of the X-axis cylinder faces the center of the rectangular frame; a vertical pressing plate 6, which is fixedly connected to the piston rod of the X-axis cylinder; a Z-axis cylinder 7, which is installed at the center of the upper surface outside the rectangular frame; and a horizontal pressing plate, which is in driving connection with the Z-axis cylinder and is directly opposite to the card slot. The card slot is used to place the reducing short pipe, especially suitable for bent pipes. The bent part of the bent pipe is placed in the card slot to maintain stability. The two vertical pressing plates and the horizontal pressing plate can perform pressure tests on the reducing short pipe from different angles.

[0018] As a preferred example of the present utility model, an extension base 8 is provided outside the rectangular frame, and an auxiliary cylinder 9 extending towards the card slot is fixedly connected to the extension base. An auxiliary vertical pressing plate is fixedly connected to the piston rod of the auxiliary cylinder.

[0019] As Figure 2 , Figure 3 As shown in the figure, as a preferred example of the present utility model, the card slot includes a retaining dam. The two top sides of the retaining dam have horizontal sections 21 extending inwards. The end of the horizontal section is hinged with a side baffle 22. Linear driving mechanisms 23 extending into the retaining dam are installed on both sides of the retaining dam. The linear driving mechanisms are in contact with the side baffle. When the reducing short pipe has a particularly complex shape, the accommodating space inside the card slot can be changed by pushing the side baffle through the linear driving mechanisms to cooperate with the stable placement of the reducing short pipe. The linear driving mechanism is a cylinder, and the piston rod of the cylinder is in contact with the side baffle.

[0020] As a preferred example of the present utility model, a transfer table 10 extends outwards from the rectangular frame. One end of the transfer table is adjacent to the card slot. The transfer table is used to place the reducing short pipe to be subjected to a pressure test or the reducing short pipe that has completed the pressure test. A conveyor belt is installed on the surface of the transfer table, and the reducing short pipe is automatically conveyed through the conveyor belt.

Without departing from the spirit of the present invention, various transformations made to the present invention fall within the protection scope of the present invention.
