Description

Technical Field

[0001] The utility model belongs to the technical field of valve sealing test, in particular to a petroleum pipeline valve sealing test device. Background Art

[0002] Oil pipeline valves are very important components in the oil and gas industry. They are mainly used to control the flow and cutoff of fluids (such as crude oil, natural gas, water, etc.) in pipelines. They usually have high reliability and strict sealing performance requirements to prevent leakage, ensure process safety, and comply with relevant environmental regulations. At present, when conducting oil pipeline valve sealing tests, it is usually necessary to use clamping devices to fix the valves. However, traditional clamping components may block the main parts of the valve, thereby affecting the test accuracy in these areas. Utility Model Content

[0003] In order to overcome the above defects, the utility model provides a petroleum pipeline valve sealing test device, which solves the problem that the traditional clamping assembly may block the main part of the valve, thereby affecting the test accuracy of these areas.

[0004] To achieve the above object, the utility model provides the following technical solutions: a petroleum pipeline valve sealing test device, comprising a support frame, a water spray assembly is connected to the support frame, a hose is connected to the water spray assembly, a shielding device is arranged inside the support frame, a fixing device is connected inside the shielding device, the shielding device comprises a shell, the fixing device comprises a fixing plate, and a vertical plate is connected to the fixing plate;

[0005] The front of the vertical plate is connected to a hydraulic cylinder, the front of the vertical plate is connected to a fixed clamping plate, the fixed clamping plate is connected to a first rubber plate, the hydraulic cylinder is connected to a movable clamping plate, the movable clamping plate is connected to a second rubber plate, and a pipe is connected through the second rubber plate.

[0006] As a further solution of the utility model: the fixing plate is connected in the shell, and the hose is connected in the pipeline.

[0007] As a further solution of the utility model: the first rubber plate and the second rubber plate are located correspondingly, and the vertical plate is connected in the shell.

[0008] As a further solution of the utility model: the shell is connected in the support frame, the front of the shell is connected with a hinge, and the hinge is connected with a flip cover outside.

[0009] As a further solution of the utility model: the flip cover is overlapped on the shell, and a handle is connected to the flip cover.

[0010] As a further solution of the utility model: a long groove is provided in the flip cover, and an observation window is provided on the front side of the shell.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The oil pipeline valve sealing test device is provided with a hydraulic cylinder, a fixed clamping plate, a first rubber plate, a movable clamping plate, a second rubber plate and a pipeline. When the valve needs to be clamped, the valve is first placed on the fixed clamping plate and the valve port is aligned with the first rubber plate, and then the hydraulic cylinder is started. The hydraulic cylinder drives the movable clamping plate and the second rubber plate to move. Then, when the movable clamping plate moves to the height position of the valve, the operation of the hydraulic cylinder is stopped. At this time, the first rubber plate and the second rubber plate clamp the valve. Then, the water spraying assembly is started, and the water spraying assembly injects water into the pipeline through a hose. The water flow through the pipeline flows into the valve, thereby achieving that the main part of the valve will not be blocked when the fixed valve is clamped, so that the test accuracy of these areas will not be affected.

[0013] 2. The oil pipeline valve sealing test device is provided with a shell, hinges, flaps, handles, long grooves and observation windows. When the valve needs to be tested, the handle is pulled, and the handle drives the flap to rotate through the hinges. Then the flap is overlapped on the shell, and the test is carried out at this time. When the valve leaks, the shell and the flap can block the water flow, so that the splashing of the water flow will not fly out of the working area, avoiding the problem of water splashing everywhere.
