Description

Technical Field

[0001] The utility model relates to the technical field of pressure switches, in particular to a pressure switch connector. Background Art

[0002] The pressure switch uses a high-precision, high-stability pressure sensor and transmission circuit, and then uses a dedicated CPU modular signal processing technology to achieve the detection, display, alarm and control signal output of the medium pressure signal. There are many pressure switch calibration connectors, but they do not match the turbine safety oil pressure and EH oil pressure pressure switch connectors. When the pressure switch is installed and removed during calibration, the thread of the pressure switch is often damaged, resulting in the need to purchase connectors and replace the pressure switch.

[0003] Therefore, we designed a pressure switch connector that can match the turbine safety oil pressure and EH oil pressure switch connectors to avoid damage to the thread during installation and removal. Utility Model Content

[0027] Embodiment 1

[0028] Referring to Figure 1 , this is the first embodiment of the present utility model. This embodiment provides a joint that can achieve the effect of preventing the thread of the pressure switch joint from being damaged. It includes an interface component 100, a connecting component 200, and a fixing component 300. The connecting component 200 and the fixing component 300 are arranged on both sides of the interface component 100 and are used to connect the turbine safety oil pressure and the EH oil pressure switch, enabling quick installation and disassembly and preventing the threads of the turbine safety oil pressure and the EH oil pressure switch from being damaged.

[0029] Specifically, the interface component 100 includes a valve body 101, a first interface 102 provided on one side of the valve body 101, and a second interface 103 provided on the other side of the valve body 101. By providing the first interface 102 and the second interface 103 on both sides of the valve body 101, they are used to connect the turbine safety oil pressure and the EH oil pressure switch respectively, and it can effectively prevent the damage of their threads.

[0030] Further, a connecting component 200 is provided. The connecting component 200 is movably connected to the first interface 102 and includes a connecting portion 201 movably connected to the first interface 102 and a connecting joint 202 movably connected to the connecting portion 201. The connecting joint 202 is a steam turbine safety oil pressure switch joint. By providing the connecting portion 201, the two ends are respectively movably connected to the first interface 102 and the steam turbine safety oil pressure switch joint. During use, by disassembling and installing the connecting portion 201, the connection and disconnection between the steam turbine safety oil pressure switch joint and the valve body 101 are completed, and the calibration of the pressure switch is completed, which can effectively prevent the four ports from being damaged. One end of the connecting portion 201 connected to the steam turbine safety oil pressure switch joint is matched with the connection of the steam turbine safety oil pressure switch joint.

[0031] Furthermore, a fixing component 300 is provided. The fixing component 300 is movably connected to the second interface 103 and includes a fixing portion 301 movably connected to the second interface 103 and a fixing joint 302 movably connected to the fixing portion 301. The fixing joint 302 is an EH oil pressure switch joint. By providing the fixing portion 301, the two ends are respectively movably connected to the second interface 103 and the EH oil pressure switch joint. When performing the installation, disassembly, and calibration of the pressure switch, it is achieved by connecting and disconnecting the fixing portion 301, which can effectively prevent the thread from being damaged. One end of the fixing portion 301 connected to the EH oil pressure switch joint is matched with the connection of the EH oil pressure switch joint.

[0032] During use, the first interface 102 and the second interface 103 on both sides of the valve body 101 are respectively connected to the steam turbine safety oil pressure and the EH oil pressure switch joint. The two sides of the connecting portion 201 are respectively movably connected to the first interface 102 and the steam turbine safety oil pressure switch joint, and the two sides of the fixing portion 301 are respectively movably connected to the second interface 103 and the EH oil pressure switch joint. When the installation, disassembly, and calibration of the pressure switch are required, only the fixing portion 301 and the connecting portion 201 need to be connected and disconnected.

[0033] In summary, by providing the connecting component 200 and the fixing component 300 on both sides of the interface component 100, it can be matched with the steam turbine safety oil pressure and the EH oil pressure switch joint, and prevent the thread from being damaged during its installation and disassembly.

[0034] Embodiment 2

[0035] Refer to Figures 2 to 5, which is the second embodiment of the present utility model. Different from the previous embodiment, this embodiment provides further optimization of the joint, solving the problem of how to prevent the thread from being damaged. It includes that the connecting portion 201 includes a connecting member 201a movably connected to the first interface 102, and a positioning member 201b arranged between the connecting member 201a and the connecting joint 202. In the present utility model, during use, the connecting member 201a is threadedly connected to the first interface 102, the positioning member 201b is threadedly connected to the connecting joint 202, and the connecting member 201a and the positioning member 201b are movably connected.

[0036] Specifically, the connecting member 201a includes a connecting seat 201a-1 movably connected to the first interface 102, and a card slot 201a-2 arranged on the connecting seat 201a-1.

[0037] Furthermore, the positioning member 201b includes a positioning seat 201b-1 movably connected to the connecting joint 202, a connecting spring 201b-2 arranged at the end of the positioning seat 201b-1 and abutted against the connecting seat 201a-1, and a positioning rod 201b-3 arranged on the outer side of the positioning seat 201b-1 and matched with the card slot 201a-2. During use, the connecting seat 201a-1 is threadedly connected to the first interface 102, the positioning seat 201b-1 is threadedly connected to the connecting joint 202, and after aligning them, the positioning seat 201b-1 is inserted into the bottom end of the connecting seat 201a-1, compressing the connecting spring 201b-2. The connecting spring 201b-2 can make the connection between the positioning seat 201b-1 and the connecting seat 201a-1 more firm. Then rotate the positioning seat 201b-1 so that the positioning rod 201b-3 is fixed in the card slot 201a-2, connecting the connecting member 201a and the positioning member 201b. In the present utility model, the card slot is L-shaped, including a circular slot horizontally arranged on the connecting seat 201a-1 and a vertical slot vertically arranged on the connecting seat 201a-1 and connected to the circular slot. When it needs to be disconnected, just rotate the positioning seat 201b-1 to separate the locking positioning rod 201b-3 from the circular slot of the card slot 201a-2, rotate it into the vertical slot, and then directly pull out the positioning seat 201b-1.

[0038] Among them, the fixing portion 301 includes a fixing member 301a movably connected to the second interface 103, a mounting member 301b movably connected to the fixing member 301a, and a locking member 301c arranged between the fixing member 301a and the mounting member 301b. In the present utility model, the fixing member 301a is threadedly connected to the second interface 103, the mounting member 301b is threadedly connected to the fixing joint 302, and the fixing member 301a and the mounting member 301b are firmly connected through the locking member 301c.

[0039] Further, the fixing member 301a includes a fixing base 301a-1 movably connected to the second interface 103, a limiting block 301a-2 movably disposed inside the fixing base 301a-1, and a return spring 301a-3 disposed between the limiting block 301a-2 and the fixing base 301a-1.

[0040] Preferably, the mounting member 301b includes a mounting base 301b-1 movably connected to the fixing base 301a-1, a mounting block 301b-2 slidably disposed inside the mounting base 301b-1 and abutted against the limiting block 301a-2, and a limiting spring 301b-3 disposed between the mounting base 301b-1 and the mounting block 301b-2. The locking member 301c includes two sets of locking grooves 301c-1 horizontally disposed on the mounting base 301b-1 and the fixing base 301a-1, limiting grooves 301c-2 vertically disposed on both sides of the locking grooves 301c-1, a locking block 301c-3 movably disposed in the locking grooves 301c-1, and clamping blocks 301c-4 disposed on both sides of the locking block 301c-3 and matching with the limiting grooves 301c-2. When in use, the fixing base 301a-1 and the mounting base 301b-1 are attached to each other, so that the limiting block 301a-2 compresses the mounting block 301b-2 toward the mounting base 301b-1 side. At the same time, the mounting block 301b-2 also provides a thrust to the limiting block 301a-2, while compressing the return spring 301a-3 and the limiting spring 301b-3. The return spring 301a-3 and the limiting spring 301b-3 can make the connection between the fixing base 301a-1 and the mounting base 301b-1 tighter. Then the locking block 301c-3 is inserted into the locking groove 301c-1, and the locking block 301c-3 is rotated 90°, so that the clamping blocks 301c-4 on both sides of the locking block 301c-3 are clamped into the limiting grooves 301c-2, making the fixing base 301a-1 and the mounting base 301b-1 firmly connected. When it is necessary to separate the fixing base 301a-1 and the mounting base 301b-1, only the locking block 301c-3 needs to be rotated 90° to separate the clamping blocks 301c-4 on both sides of the locking block 301c-3 from the limiting grooves 301c-2, and then the mounting member 301b can be directly pulled out.

[0041] Further, a snap ring 400 matching with the mounting block 301b-2 is disposed inside the mounting base 301b-1. The snap ring 400 is used to limit the position of the limiting block 301a-2 within the mounting base 301b-1.

[0042] In use, the connecting member 201a and the fixing member 301a are respectively threadedly connected and movably installed on the first interface 102 and the second interface 103. Then, the positioning member 201b and the mounting member 301b are threadedly connected to the connecting joint 202 and the fixing joint 302. When pressure switch calibration installation and removal are required, the connecting member 201a and the positioning member 201b are connected and disconnected through the card slot 201a-2 and the positioning rod 201b-3, and then the mounting member 301b and the fixing member 301a are connected and disconnected through the locking member 301c, which can effectively prevent the thread from being damaged due to the relatively large number of installation and disassembly times during threaded connection.

[0043] In summary, by providing the connecting portion 201 and the fixing portion 301, it can be matched with the pressure switch joints of the steam turbine safety oil pressure and the EH oil pressure. During installation and removal, it is not necessary to install and remove their joints by threading, which can effectively protect their threads.

[0044] Embodiment 3

[0045] Refer to Figures 2 to 5 , which is the third embodiment of the present utility model. Different from the previous embodiment, this embodiment provides a joint, which solves the problem of better matching with the pressure switch joints of the steam turbine safety oil pressure and the EH oil pressure. A first sealing gasket 500 is provided between the positioning seat 201b-1 and the connecting seat 201a-1. By providing the first sealing gasket 500, the fixing seat 301a-1 and the mounting seat 301b-1 are connected and sealed to prevent leakage. A sealing gasket is also provided between the fixing seat 301a-1 and the mounting seat 301b-1, which can play a role in preventing leakage.

[0046] In summary, by providing the sealing gasket, the connecting member 201a and the positioning member 201b, and the fixing member 301a and the mounting member 301b can be effectively sealed.
