Abstract
Description
Technical Field
[0001] This utility model relates to the field of injection equipment technology, specifically to a four-row valve head with a pressure sensor. Background Technology
[0002] The quadruple valve head integrates four independent valve heads into a single structure, making it a rather unique component in fluid control systems.
[0003] Each valve in the four-way valve head can be controlled independently, enabling operations such as opening, closing, and adjusting the opening degree. This allows the four-way valve head to individually control parameters such as fluid flow rate and direction in each channel according to specific fluid control needs. However, existing four-way valve heads do not have pressure detection function within the flow channels, making it difficult to detect the flow resistance of each channel in real time. Furthermore, the four flow channels of the valve body cannot be merged, thus making it impossible to combine reagents. Therefore, we propose a four-way valve head with a pressure sensor. Utility Model Content
[0004] One of the technical problems that this application aims to solve is that the four-way valve head does not have a detection function, cannot detect the flow resistance of each flow channel in real time, and cannot perform flow fusion, so the combination of reagents cannot be completed.
[0005] To address the aforementioned technical problems, this application provides a four-unit valve head with pressure sensors, including a lower valve head, an upper valve head at the upper end of the lower valve head, a valve head cover at the upper end of the lower valve head and located on the outer wall of the upper valve head, multiple solenoid valves connected to the rear end of the lower valve head, and multiple mounting slots at the upper end of the lower valve head. It also includes:
[0006] A pressure detection mechanism is installed inside the mounting groove, and the status of each flow channel can be monitored in real time through the pressure detection mechanism.
[0007] The installation mechanism is located inside the lower valve head and on one side of the pressure detection mechanism, allowing for quick assembly and disassembly of the pressure detection mechanism.
[0008] In some embodiments, the pressure detection mechanism includes a pressure plate and a pressure sensor. The pressure plate is slidably disposed on the upper end of the lower valve head and located in the mounting groove. The pressure sensor is disposed inside the mounting groove, and a sealing ring is provided at the lower end of the pressure sensor.
[0009] The above technical solution involves using a pressure detection mechanism to perform real-time pressure detection on the flow channel of the valve body.
[0010] In some embodiments, the mounting mechanism includes a sliding assembly and a positioning assembly, wherein the sliding assembly causes the pressure plate to slide on the lower valve head, and the positioning assembly causes the pressure sensor to be mounted and positioned.
[0011] The above technical solution allows for easy installation of the pressure sensor by the installation mechanism.
[0012] In some embodiments, the sliding assembly includes a plurality of slide grooves and a slider. The plurality of slide grooves are formed on the lower valve head and located on both sides of the mounting groove. Each of the plurality of slide grooves is provided with a slide rod. Each of the slide rods is fitted with a first spring on its outer wall. The slider is disposed on both sides of the lower end of the pressure plate and slides at the upper limit of the slide rod.
[0013] The above technical solution allows the pressure plate to slide on the lower valve head via a sliding component.
[0014] In some embodiments, the positioning component includes a movable groove, a protrusion, and an elastic component. The movable groove is formed inside the lower valve head and located at the front end of the mounting groove. A half-tooth is rotatably provided inside the movable groove. An arc-shaped rod is fixedly connected to one side of the half-tooth. A positioning block is fixedly connected to the end of the arc-shaped rod away from the half-tooth. A rack is engaged on one side of the half-tooth. An L-shaped connecting rod is connected to one side of the rack. A pressing head is connected to the other end of the L-shaped connecting rod. The protrusion is disposed on the side wall of the pressure sensor.
[0015] The above technical solution allows the pressure sensor to be positioned by pressing the positioning block against the protrusion of the pressure sensor when the pressure plate is slid to the front end by the positioning component.
[0016] In some embodiments, the elastic component is disposed inside the lower valve head and located at the front end of the L-shaped connecting rod, and the elastic component includes a second spring, with a push block fixedly connected to the rear end of the second spring;
[0017] The above technical solution involves using a second spring to push the push block, causing the L-shaped connecting rod to reset.
[0018] In some embodiments, a flow channel is provided inside the lower valve head, through which the four valve ports of the lower valve head are connected, and the flow channel and the valve port path are consistent.
[0019] The above technical solution connects the valve ports through the flow channel, which can satisfy the fusion of four reagents and also perform cleaning at the same time.
[0020] This utility model has at least the following beneficial effects:
[0021] 1. The installation mechanism facilitates quick assembly and disassembly of the pressure sensor. Insert the pressure sensor into the mounting slot and release the pressure plate. The slider at the lower end of the pressure plate is reset by the first spring, causing the slider to move the pressure plate and press and position the upper end of the pressure sensor. When the slider reaches the front end of the groove, it presses against the extrusion head, which moves inward, causing the toothed plate to rotate. This moves the positioning block into the mounting slot, pressing the protrusion on the pressure sensor and further improving the stability of the pressure sensor installation. This convenient pressure sensor assembly and disassembly greatly benefits the operator.
[0022] 2. The four-way valve head has pressure sensors added to each flow channel, which can detect the flow resistance of each flow channel in real time and can self-test the pressure resistance at any time. At the same time, the four flow channels are connected to meet the fusion of four reagents and can also be cleaned at the same time. Attached Figure Description

[0033] Pressure detection mechanism 6 is installed inside the mounting groove 5. The pressure detection mechanism 6 can monitor the status of each flow channel in real time.
[0034] The mounting mechanism 7 is located inside the lower valve head 1 and on one side of the pressure detection mechanism 6. The pressure detection mechanism 6 can be quickly disassembled and assembled through the mounting mechanism 7.
[0035] The pressure detection mechanism 6 includes a pressure plate 61 and a pressure sensor 62. The pressure plate 61 is slidably disposed on the upper end of the lower valve head 1 and located in the mounting groove 5. The pressure sensor 62 is disposed inside the mounting groove 5. A sealing ring 63 is provided at the lower end of the pressure sensor 62. The pressure detection mechanism 6 performs real-time pressure detection on the flow channel of the valve body.
[0036] The mounting mechanism 7 includes a sliding component 8 and a positioning component 9. The sliding component 8 allows the pressure plate 61 to slide on the lower valve head 1, and the positioning component 9 allows the pressure sensor 62 to be installed and positioned. The mounting mechanism 7 facilitates the installation of the pressure sensor 62 by the operator.
[0037] The sliding assembly 8 includes multiple sliding grooves 81 and sliders 84. The multiple sliding grooves 81 are opened on the lower valve head 1 and located on both sides of the mounting groove 5. Each of the multiple sliding grooves 81 is provided with a sliding rod 82. Each of the multiple sliding rods 82 is fitted with a first spring 83 on its outer wall. The sliders 84 are located on both sides of the lower end of the pressure plate 61. The sliders 84 slide at the upper limit of the sliding rods 82. The sliding assembly 8 makes the pressure plate 61 slide on the lower valve head 1.
[0038] The positioning component 9 includes a movable groove 91, a protrusion 98, and an elastic component 99. The movable groove 91 is opened inside the lower valve head 1 and located at the front end of the mounting groove 5. A half tooth 92 is rotatably provided inside the movable groove 91. An arc-shaped rod 93 is fixedly connected to one side of the half tooth 92. A positioning block 94 is fixedly connected to the end of the arc-shaped rod 93 away from the half tooth 92. A rack 95 is engaged on one side of the half tooth 92. An L-shaped connecting rod 96 is connected to one side of the rack 95.
