DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail in conjunction with the embodiments and drawings. Here, the illustrative embodiments of this application and their descriptions are used to explain this application, but are not intended to limit this application.

[0036] refer to Figures 1 to 9 ,like Figure 1As shown, this embodiment provides a manual valve that is anti-theft and anti-misoperation, including: a valve body 1, a protective shell 2 and a protective cover. The protective shell 2 is installed on the valve body 1, and first grooves 21 are provided on the left and right sides of the lower end of the protective shell 2. The first grooves 21 match the inlet and outlet pipes of the valve body 1, so that the protective shell 2 is installed firmly; the protective cover is connected to the protective shell 2 through a number of anti-theft mechanisms; specifically, the protective cover includes an upper cover 3 and a lower cover 4 fixedly connected to each other, and a handle 231 for easy handholding is installed on the upper cover 3. The anti-theft mechanism includes a mounting mechanism 5 and an unlocker 9. The mounting mechanism 5 is installed in the lower cover 4, and the mounting mechanism 5 can be plugged into the protective shell 2, thereby realizing locking between the protective cover and the protective shell 2. The unlocker 9 is adapted to the mounting mechanism 5, and the unlocker 9 can operate the mounting mechanism 5 to detach from the protective shell 2, thereby realizing unlocking the protective cover.

[0037] Preferably, if Figure 2 As shown, the manual valve further includes an alarm 8 and a vibration sensor 7 . Both the alarm 8 and the vibration sensor 7 are mounted on the protective shell 2 , and the alarm 8 is electrically connected to the vibration sensor 7 .

[0038] Specifically, the alarm 8 and the vibration sensor 7 are both controlled by the controller. When the protective shell 2 is hit or impacted by external force, the vibration sensor 7 can detect the vibration of the protective shell 2, and then control the alarm 8 to start through the controller. The alarm 8 sounds an alarm, which can prevent other people from violently opening the protective shell 2 to steal, thereby improving the safety protection effect.

[0039] like Figure 8 and Figure 9 As shown, the mounting mechanism 5 includes: a rotating shaft 51, a cam 52, a connecting frame 53 and a compression spring 56. The rotating shaft 51 is rotatably mounted on the lower cover 4, and the lower end extends into the mounting groove 42; the cam 52 is connected to the lower end of the rotating shaft 51; the connecting frame 53 is slidably set in the mounting groove 42, and the cam 52 can be supported on the connecting frame 53; the compression spring 56 is accommodated in the mounting groove 42, and the upper end of the compression spring 56 is pressed against the lower end surface of the connecting frame 53, and the lower end of the compression spring 56 is pressed against the bottom wall of the mounting groove 42; a locking assembly, the locking assembly is connected to the connecting frame 53, and the locking assembly can be inserted into the corresponding limit groove 24 on the protective shell 2 to achieve locking between the lower cover 4 and the protective shell 2.

[0040] Preferably, the locking assembly includes a sliding block 54 and a limiting rod 55 that are connected to each other. The sliding block 54 is slidably set in the limiting groove 24. The upper end of the connecting frame 53 is connected to the lower end of the sliding block 54. The upper end of the sliding block 54 is connected to the lower end of the limiting rod 55. The upper end of the limiting rod 55 passes through the end of the lower cover 4 and can be inserted into the corresponding limiting groove 24.

[0041] like Figure 4 and Figure 8 As shown, there are two mounting mechanisms 5 , which are symmetrically arranged in the corresponding mounting grooves 42 , so that the lower cover 4 and the protective shell 2 can be reliably connected.

[0042] like Figure 5 As shown, the upper end of the rotating shaft 51 extends upward and extends into the through hole 32 of the upper cover 3. A plurality of annular slots 511 are provided at the upper end of the rotating shaft 51. The unlocking tool 9 can be inserted into the plurality of slots 511. By operating the unlocking tool 9, the rotating shaft 51 can be rotated, thereby realizing the removal of the protective cover.

[0043] like Figure 6 As shown, the unlocking device 9 includes a handle portion 91, a driving portion 92 and a plurality of insert blocks 93 which are integrally connected. The insert blocks 93 are adapted to the corresponding slots 511. The insert blocks 93 have a rectangular cross-section and are difficult to process. Specific insert blocks 93 must be used to be inserted into the corresponding slots 511, thus having a good anti-theft effect.

[0044] In addition, a pair of front-to-back symmetrical through holes 32 are provided on the upper cover 3, and the upper end of the rotating shaft 51 extends into the corresponding through holes 32, so that the insert block 93 can be inserted into the through holes 32 to be plugged into the slot 511, which can further improve the safety of use.

[0045] like Figure 2 and Figure 3 As shown, two limiting ridges 41 are symmetrically provided at the lower end of the lower cover 4, and the limiting ridges 41 are adapted to the corresponding positioning grooves 23 on the protective shell 2, so that the protective cover can be installed on the protective shell 2 more conveniently and the installation position can be more accurate.

[0046] like Figure 7 As shown, a second groove 22 is provided at both the left and right ends of the protective shell 2, and the positioning groove 23 is connected to the lower end of the corresponding second groove 22. The ends of the upper cover 3 and the lower cover 4 are both accommodated in the corresponding second groove 22, so that the protective cover and the protective shell 2 fit better.

[0047] Preferably, a connector 6 is provided below the lower cover 4, and the connector 6 can be plugged into the handwheel 11 of the valve body 1. When the protective cover is removed from the protective shell 2, the handwheel 11 will be separated from the handwheel 11. When the protective cover is installed, the lower end of the connector 6 is plugged into the socket on the handwheel 11, which can prevent the handwheel 11 from loosening due to vibration or impact, thereby preventing misoperation.

[0048] Working principle: When it is necessary to access the fluid in the valve body 1, use the unlocker 9 to insert multiple plugs 93 into the slots 511, rotate the unlocker 9, so that the cam 52 rotates and squeezes the connecting frame 53, and the connecting frame 53 moves forward to drive the limit rod 55 to disengage from the limit groove 24, and then the protective cover can be removed by holding the handle 31. During installation, the unlocker is also used to retract the limit rod 55 into the installation groove 42, and then the protective cover is installed on the protective shell 2, wherein the left and right ends of the upper cover 3 and the lower cover 4 are respectively accommodated in the corresponding second groove 22, and the limit ridge 41 is inserted into the corresponding positioning groove 23. At this time, the limit rod 55 corresponds to the position of the limit groove 24, so the unlocker 9 is released, and the elastic action of the compression spring 56 can enable the connecting frame 53 to push the limit rod 55 into the corresponding limit groove 24, and the protective cover is installed.

[0049] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Those skilled in the art will appreciate that various modifications and variations of the present embodiment are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
