Description

Technical Field

[0001] The present invention relates to a valve pressure testing device, in particular to a remote-controlled valve pressure testing device applied in the field of valve testing. Background Art

[0002] Before using the valve, its sealing performance and strength need to be tested. During the test, the valve is generally installed on a valve pressure test device for testing. During the test, generally only one or several connecting branches are used to test the valve, and the remaining redundant connecting branches need to be sealed. In the prior art, when sealing, sealing plugs are often provided on the surfaces of other connecting branches to cover the other connecting branches, and the plugs and other connecting branches are mostly fixed with threads to achieve sealing for other workstations. However, this sealing method is relatively cumbersome and troublesome during installation and disassembly, and it is easy for the valve to be not tightened properly during installation, which may lead to leakage during testing.

[0003] In order to solve the above problems, the specification of Chinese patent CN219675713U discloses a valve pressure test device with a quick-install joint, including a valve pressure test device body, the top, left and right sides and front end of the valve pressure test device body are fixedly installed with connecting branches, the surface of the connecting branch is provided with a sealing structure, the sealing structure includes a sealing cover and a sealing connector, the sealing cover is movably arranged on the surface of the connecting branch, and the sealing connector is fixedly installed on the surface of the connecting branch. According to the utility model, the valve pressure test device with a quick-install joint installs the pressure test valve to be tested on the corresponding connecting branch according to the diameter of the connection through the cooperation of the connecting branch and the sealing structure, and then the remaining unused connecting branches are sealed with the sealing structure, so as to avoid the connection branch without the pressure test valve installed from leaking water or air when in use, and the provided sealing structure facilitates sealing and removal.

[0004] In the above-mentioned prior art, although it is possible to seal other connected pipes during use, it is based on the repeated removal and installation of the sealing structure, which takes a long time during the installation and removal process. At the same time, in actual use, it is also necessary to ensure that the pipe connected to the valve is sealed. The above-mentioned scheme can only seal the pipe not connected to the valve, and its use effect is not comprehensive enough. When the pipe is connected to the valve, there is an additional step of disassembling the sealing structure and then installing it, which brings greater inconvenience to the connection of the valve.

DETAILED DESCRIPTION

[0019] An implementation method of the present application is described in detail below with reference to the accompanying drawings.

[0020] The first implementation method: The present invention provides a remote control valve pressure test device, please refer to Figure 1-Figure 3 , Figure 7 , including a test pressure barrel 1, a booster pump 2 for pumping pressure medium into the test pressure barrel 1 is connected to one side of the test pressure barrel 1 through a pressure pipeline, a console 3 for controlling the operation of the booster pump 2 is installed below the booster pump 2, and a remote communication module for data exchange with an external remote controller is mounted on the console 3. The remote communication module adopts a communication module commonly used in the prior art and suitable for this embodiment (such as a wifi communication module) for realizing data and command transmission between the console 3 and the external remote controller. The external remote controller can adopt a commonly used remote control terminal, such as a mobile phone, a remote controller, a remote computer terminal, etc.; A plurality of evenly distributed connecting pipes 4 are fixed and connected to the test pressure barrel 1; The connecting pipe 4 is detachably provided with a mounting seat 5, the upper end of which is provided with a receiving groove 501 for receiving the valve access end 10, and the mounting seat 5 is also provided with a connecting hole penetrating the mounting seat 5 and communicating with the receiving groove 501; A combined seal 7 that can be movably opened and closed and a trigger mechanism for controlling the opening and closing of the combined seal 7 are installed in the communicating hole of the mounting seat 5; When the valve access end 10 is not installed, the trigger mechanism is in an initial state, and the combined seal 7 closes the connecting hole of the mounting seat 5; when the valve access end 10 is installed, the trigger mechanism operates and drives the combined seal 7 to open; after the valve access end 10 is installed, the combined seal 7 is fully opened, so that the connecting pipe 4 forms a connecting structure with the valve access end 10 through the mounting seat 5 and is sealed externally.

[0021] Based on the above structure, a mounting seat 5, a combined seal 7 and a matching trigger mechanism are added to the original connecting pipe 4, so that when the valve access end 10 is not installed, the trigger mechanism is in the initial state, and the combined seal 7 closes the communication hole of the mounting seat 5; when the valve access end 10 is installed, the trigger mechanism operates and drives the combined seal 7 to open; after the valve access end 10 is installed, the combined seal 7 is fully opened, so that the connecting pipe 4 forms a connecting structure that is mutually connected and externally sealed with the valve access end 10 through the mounting seat 5, so that the connecting pipe 4 of the remote control valve pressure test device can not only maintain a seal when the valve is not connected (connected to the valve access end 10), but also form a sealing structure connected to the valve after the valve is connected, achieving a design purpose of a dual structural effect, thereby achieving a better use effect; At the same time, the added structure makes little change to the original structure, which is conducive to modifying the existing remote control valve pressure test device, thereby facilitating promotion and use with a small improvement cost; In addition, the detachable installation method also facilitates the disassembly of the added mounting seat 5, the combined seal 7 and the matching trigger mechanism, which is convenient for subsequent replacement and maintenance, and is more convenient to use.

[0022] Figure 3-Figure 4 The combined sealing member 7 includes a movable sealing ring 701 and a fixed sealing sheet 702. The movable sealing ring 701 is vertically slidably connected to the mounting seat 5 via a movable member. The fixed sealing sheet 702 slides relative to the movable sealing ring 701. The fixed sealing sheet 702 is fixed to the inner wall of the connecting hole of the mounting seat 5 via a support rod 7021. When the trigger mechanism is triggered, the movable sealing ring 701 moves downward and separates from the fixed sealing sheet 702. At this time, the connecting hole of the mounting seat 5 is opened. When the trigger mechanism is not triggered, the movable sealing ring 701 is sleeved on the outside of the fixed sealing sheet 702 to form a plate-like structure. At this time, the connecting hole of the mounting seat 5 is closed by the movable sealing ring 701 and the fixed sealing sheet 702 to form a seal.

[0023] Through the arrangement of the movable sealing ring 701 and the fixed sealing sheet 702, when the trigger mechanism is triggered, the movable sealing ring 701 moves downward and separates from the fixed sealing sheet 702. At this time, the connecting hole of the mounting seat 5 is opened. When the trigger mechanism is not triggered, the movable sealing ring 701 is sleeved on the outside of the fixed sealing sheet 702 to form a plate-like structure. At this time, the connecting hole of the mounting seat 5 is closed by the movable sealing ring 701 and the fixed sealing sheet 702 to form a seal, thereby ensuring that the connecting pipe 4 is sealed when the valve is not connected, and an external sealing structure connected to the valve access end 10 is formed when the valve is connected to the connecting pipe 4, thereby achieving a multi-state use effect and improving the practicality and convenience of the remote control valve pressure testing device.

[0024] Figure 3-Figure 6 The bottom surface of the receiving groove 501 of the mounting seat 5 is provided with a mounting groove 502, and one side of the mounting groove 502 is provided with a through hole 503 connected with the connecting hole of the mounting seat 5, and the through hole 503 is for the movable part to slide through; The trigger member includes a positioning column 6 and a reset member. The positioning column 6 is slidably inserted into the mounting groove 502. The lower end of the positioning column 6 is fixed to one end of the movable member. The reset member is installed below the positioning column 6 and drives the positioning column 6 to move upward. The reset member includes a reset spring 601, and the upper and lower ends of the reset spring 601 are respectively fixed to the bottom surface of the movable member and the inner bottom wall of the mounting groove 502; The positioning column 6 is adapted to the flange connection hole of the valve access end 10; The movable part includes a connecting contact plate 7011, one end of the connecting contact plate 7011 is fixed to the peripheral side of the movable sealing ring 701, the other end of the connecting contact plate 7011 is fixed to the lower end of the positioning column 6, and the bottom surface of the connecting contact plate 7011 is fixed to the upper end of the return spring 601; The connecting contact plate 7011 is slidably inserted into the through hole 503, and the connecting contact plate 7011 is a deformable soft material; A sealing groove 7012 is provided on the upper surface of the movable sealing ring 701. When the movable sealing ring 701 and the fixed sealing sheet 702 are closed, the support rod 7021 is embedded in the sealing groove 7012 to form a sealed whole. A limiting member for limiting the position of the positioning column 6 is also installed on the upper end of the mounting seat 5; An internal thread is provided at the upper end of the inner wall of the receiving groove 501; The limiting member includes a pressing cover 8, which is provided with an external thread matching the internal thread of the accommodating groove 501 on its circumference. The pressing cover 8 is movably sleeved on the outside of the valve access end 10, and the inner wall of the pressing cover 8 is sealed and fitted with the outer wall of the valve access end 10.

[0025] Through the arrangement of the positioning column 6, the return spring 601 and the pressing cover 8, when the valve access end 10 is not connected, the positioning column 6 rises under the elastic force of the return spring 601, and drives the movable sealing ring 701 to rise synchronously through the connecting contact plate 7011. After the movable sealing ring 701 rises, it is sleeved on the outer side of the fixed sealing sheet 702 and forms a sealed whole with the fixed sealing sheet 702. At this time, the support rod 7021 is embedded in the sealing groove 7012 and forms a sealed whole, thereby forming a seal for the connecting hole of the mounting seat 5. At this time, the pressing cover 8 is not completely screwed into the mounting seat 5; When the valve access end 10 is connected, firstly, the hole on the flange ring of the valve access end 10 is plugged and matched with the positioning column 6, and then the pressing cover 8 is completely screwed into the mounting seat 5, so that the lower end of the pressing cover 8 squeezes the positioning column 6 and moves downward, so that the positioning column 6 drives the movable sealing ring 701 to drop synchronously through the connecting contact plate 7011, thereby separating from the fixed sealing sheet 702, and the support rod 7021 is separated from the sealing groove 7012, so that the connecting hole of the mounting seat 5 is opened. At this time, since the lower end and the surrounding side of the valve access end 10 are respectively pressed against the bottom surface and the side wall of the accommodating groove 501, a sealing structure is formed, which can ensure that the valve access end 10 is connected to the connecting pipe 4 while maintaining external sealing, thereby ensuring the effectiveness of the pressure test; This ultimately achieves the goal of ensuring that the connecting pipe 4 remains sealed when no valve is connected, and that an external sealing structure that is connected to the valve access end 10 is formed when the valve is connected to the connecting pipe 4, thereby achieving a multi-state use effect and improving the practicality and convenience of the remote control valve pressure testing device.

[0026] Figure 5 and Figure 8 It is shown that flexible sealing rings 505 are formed at the upper and lower edges of the connecting hole of the mounting seat 5. The two flexible sealing rings 505 are respectively interference-fitted with the flange ring end faces of the connecting pipe 4 and the flange ring end faces of the valve access end 10. The provision of the two flexible sealing rings 505 can further improve the sealing performance of the mounting seat 5 itself, the connecting pipe 4 and the valve access end 10, thereby ensuring the sealing connection effect between the valve access end 10 and the connecting pipe 4 after the valve is connected. A lower thread groove 504 opening downward is provided on the bottom surface of the mounting seat 5, and the connecting pipe 4 is screwed and fixed to the lower thread groove 504 by means of bolts 401. Through the provision of the lower thread groove 504, the mounting seat 5 can be detachably mounted on the connecting pipe 4, which is convenient for installation improvement of the existing end of the connecting pipe 4 on the one hand, and also convenient for subsequent disassembly and maintenance on the other hand.

[0027] Figure 7-Figure 8 It is shown that an operating ring 9 with an inner diameter larger than the outer diameter of the valve access end 10 is fixed to the upper end of the pressing cover 8, and a concave-convex portion 901 is formed on the outer side of the operating ring 9 for increasing the friction force, so that the user can rotate the pressing cover 8 into or out of the mounting seat 5 for easy operation.

[0028] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
