Abstract
Description
Technical Field
[0001] The utility model belongs to the field of flow switches, in particular to a combined float flow switch. Background Art
[0002] In the chemical production process, the function of the float flow switch is to detect whether the liquid in the process pipeline has reached the preset flow rate, and output an electrical signal indicating whether it has reached the standard to the control system, which then responds. The working principle of the float flow switch is to preset the float position. When the liquid flow in the pipeline pushes the float up, the float drives the connecting rod, and the connecting rod moves up to trigger the switch, thereby outputting an alarm signal, indicating that the liquid flow in the pipeline has reached the preset value.
[0003] Existing float flow switches are all preset in advance according to the application situation. Due to the integrated design, pipes with different diameters need to be equipped with flow switches with corresponding connecting rod lengths, which have poor versatility and increase the cost of use. Utility Model Content
[0004] The utility model aims to provide a combined float flow switch to solve the problem that the existing float flow switch cannot adapt to pipelines with different diameters.
[0005] The technical solution adopted by the utility model is as follows:
[0006] A combined float flow switch comprises a control end meter head, a meter body connecting rod, a float and a mounting flange. A mounting rod is arranged on the upper end of the float, and the mounting rod is connected to the meter body connecting rod through a threaded connection, and a fixing nut is arranged at the connection.
[0007] Preferably, the meter body connecting rod is provided with a mounting nut, and there are multiple mounting nuts.
[0008] Preferably, the mounting rod is provided with a thread matching with the mounting nut.
[0009] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:
[0010] Through the assembly design of the float part and the meter body part, the position of the mounting rod can be adjusted to make the float in different positions, or the float and the mounting rod part can be replaced, so that the float flow switch can be suitable for pipes of various diameters. Because the float and the mounting rod part have lower costs, resources are also saved. BRIEF DESCRIPTION OF THE DRAWINGS
[0011] Figure 1 It is a schematic diagram of the overall structure of the utility model.
[0012] Among them: 1-control end meter head, 2-meter body connecting rod, 3-float, 4-mounting flange, 5-mounting rod, 6-fixing nut, 7-mounting nut. DETAILED DESCRIPTION
[0013] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.
[0014] like Figure 1 As shown, a combined float flow switch includes a control end meter head 1, a meter body connecting rod 2, a float 3 and a mounting flange 4. A mounting rod 5 is provided on the upper end of the float 3. The mounting rod 5 is connected to the meter body connecting rod 2 through a threaded connection. A fixing nut 6 is provided at the connection. The meter body connecting rod 2 is provided with a mounting nut 7. There are multiple mounting nuts 7. The mounting rod 5 is provided with a long thread that matches the mounting nut 7, so that the mounting rod 5 can be connected to the meter body connecting rod 2, and the fixing nut 6 can fix the two rods.
[0015] How it works:
[0016] After determining the pipe diameter for installing the float flow switch, adjust the target position of the float 3 in the pipe as required. The adjustment method is to first loosen all the fixing nuts 6, then rotate the float 3 and the installation rod 5 to move it up and down relative to the meter body connecting rod 2. After reaching the appropriate position, tighten all the fixing nuts 6, and finally install the device on the pipe. When the pipe diameter or the use environment of the installed pipe changes, the position of the float 3 can be changed in the same way.
[0017] Meanwhile, when the float ball 3 of the device is damaged or does not meet the use requirements, the entire float ball 3 and the mounting rod 5 can be partially disassembled and replaced.
[0018] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be modified and varied. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
