Abstract
Description
A cross valve leakage detection device Technical Field
[0001] This utility model belongs to the field of cross valves, specifically, it relates to a cross valve leakage detection device. Background Technology
[0002] The sterile cross valve consists of two symmetrical valve bodies with a cross-shaped cross section and a rotatable valve core in the middle. The valve core has two channels that are connected to the two outlets of the valve body respectively. The internal surface of the valve body is smooth and has no dead corners to ensure sterility.
[0003] Existing cross valves require frequent checks by staff during production. Over long hours, staff may become fatigued and prone to oversights. If leaks or other abnormalities occur, they may not be detected in time, which can easily affect the quality of the valve.
[0004] In view of this, this utility model is proposed. Summary of the Invention
[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a cross valve leakage detection device. This solves the problem that the prior art requires staff to check it frequently. During long working hours, staff may become mentally fatigued and easily overlook or miss the problem. When leakage occurs, it cannot be detected in time, which can easily affect the quality of the product.
[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:
[0007] A cross valve leakage detection device includes: a cross valve body, a connecting pipe installed on one side of the cross valve body, two fixing blocks installed on the surface of the connecting pipe, and a triggering device installed inside the fixing blocks;
[0008] The triggering device includes a movable block that is slidably fitted inside a connecting pipe. A fixed post is installed inside the connecting pipe. An arc-shaped sliding block is slidably fitted inside the fixed post. One end of the arc-shaped sliding block extending to the outside of the fixed post is fixedly connected to the movable block. A limiting plate is installed inside the fixed post. A sliding rod is slidably fitted inside the fixed post. A fixed plate is installed on the surface of the sliding rod located inside the fixed post. A spring is installed between the fixed plate and the limiting plate. One end of the sliding rod located outside the fixed post is fixedly connected to the movable block.
[0009] Optionally, a retaining ring is installed inside the connecting pipe, and a push plate is installed on one side of the retaining ring.
[0010] Optionally, the movable block has a sliding groove inside, and the push plate slides with the movable block through the sliding groove.
[0011] Optionally, a triggering device is provided inside the sliding groove, and the push plate contacts the triggering device through the sliding groove.
[0012] Optionally, a transmitter is provided on one side of the fixed block, and the transmitter has wires inside, and the transmitter is electrically connected to the triggering device.
[0013] Optionally, the moving block has a conical groove inside, and the fixed column has a flow groove inside, with the larger opening of the conical groove located on one side of the material flow direction.
[0014] Optionally, a limiting block is installed inside the fixed column, and the limiting block slides in conjunction with the sliding rod.
[0015] Optionally, a detection device may be installed at one end of the conductor.
[0016] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:
[0017] During operation, a conical trough is set up. When the material flows to the larger opening of the trough, the moving block moves. When the moving block moves away from the trigger device, the alarm is deactivated. When the connecting pipe is damaged and leaks, the air pressure inside the connecting pipe decreases. Under the action of the spring, the sliding rod pushes the moving block to move, causing the trigger device to contact the push plate and activate the trigger device. The signal is then transmitted to the detection device via the transmitter and wire. The detection device receives the signal and transmits it to the alarm device, which then issues an alarm. This eliminates the need for frequent inspections by personnel. Inspections are only required when the alarm device issues an alarm. Leaks and abnormalities can be detected promptly through the alarm device without affecting the quality.

Detailed Implementation
[0028] The present invention will now be described in further detail with reference to the accompanying drawings.
[0029] Please refer to Figures 1-5. In this embodiment, a cross valve leakage detection device is provided, including a cross valve body 1, a connecting pipe 2 is installed on one side of the cross valve body 1, two fixing blocks 3 are installed on the surface of the connecting pipe 2, and a triggering device is installed inside the fixing blocks 3.
[0030] The triggering device includes a movable block 9, which is slidably fitted inside the connecting pipe 2. A fixed post 7 is installed inside the connecting pipe 2. An arc-shaped sliding block 19 is slidably fitted inside the fixed post 7. One end of the arc-shaped sliding block 19 extending to the outside of the fixed post 7 is fixedly connected to the movable block 9. A limiting plate 14 is installed inside the fixed post 7. A sliding rod 8 is slidably fitted inside the fixed post 7. A fixed plate 13 is installed on the surface of the sliding rod 8 located inside the fixed post 7. A spring 15 is installed between the fixed plate 13 and the limiting plate 14. One end of the sliding rod 8 located outside the fixed post 7 is fixedly connected to the movable block 9.
[0031] One application of this embodiment is as follows: During use, the air pressure inside the connecting pipe 2 is relatively high. By setting a conical groove 10, when the material flows to the larger opening of the conical groove 10, the moving block 9 moves. When the moving block 9 moves away from the triggering device 21, the alarm can be deactivated. When the connecting pipe 2 is damaged and leaks, the air pressure inside the connecting pipe 2 will decrease. Under the action of the spring 15, the sliding rod 8 pushes the moving block 9 to move, thereby making the triggering device 21 contact with the push plate 16, which can activate the triggering device 21. The signal can then be transmitted to the detection device 6 through the transmitter 4 and the wire 5. The detection device 6 receives the signal and transmits it to the alarm device 20, which then issues an alarm. By setting a limit block 18, the sliding rod 8 can be limited, maintaining the stability of the sliding rod 8 during operation.
[0032] In this embodiment, the movable block 9 has a sliding groove 17 inside, and the push plate 16 slides with the movable block 9 through the sliding groove 17. A triggering device 21 is provided inside the sliding groove 17, and the push plate 16 contacts the triggering device 21 through the sliding groove 17. The sliding rod 8 pushes the movable block 9 to move, so that the triggering device 21 contacts the push plate 16, which can activate the triggering device 21.
[0033] In this embodiment, a transmitter 4 is provided on one side of the fixing block 3. A wire 5 is provided inside the transmitter 4, and the transmitter 4 is electrically connected to the triggering device 21. The signal is transmitted to the detection device 6 through the transmitter 4 and the wire 5, and the detection device 6 receives the signal and transmits it to the alarm device 20.
[0034] In this embodiment, the moving block 9 has a conical groove 10 inside, and the fixed column 7 has a flow groove 11 inside. The larger opening of the conical groove 10 is located on one side of the material flow direction. By setting the conical groove 10, when the material flows to the larger opening of the conical groove 10, the moving block 9 moves. When the moving block 9 moves away from the triggering device 21, the alarm can be deactivated.
[0035] In this embodiment, a limiting block 18 is installed inside the fixed column 7, and the limiting block 18 slides with the sliding rod 8. By setting the limiting block 18, the sliding rod 8 can be limited, and the stability of the sliding rod 8 during operation can be maintained.
