Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a valve group with anti-loosening function. Background Art

[0002] A valve is a pipeline accessory used to open and close pipelines, control the flow direction, adjust and control the parameters of the transported medium, and is commonly used in various industries. When designing a valve, for the convenience of assembly, a nut is usually sleeved on its control component, and the control component is assembled on the valve body by threadedly connecting the nut to the valve body. To prevent the nut from loosening during use due to external forces, resulting in the loosening of the connection between the control component and the valve body, an anti-loosening component assembled on the valve body is usually added to the side of the nut. The anti-loosening component is engaged with the nut to prevent the nut from rotating.

[0003] In this design, the installation position of the anti-loosening component is single, and the degree of tightness of the nut tightened on the valve body is different, so the orientation of its corner is different. This makes it necessary to observe whether the installation hole formed on the anti-loosening component corresponds to the installation hole formed on the valve body by sleeving the anti-loosening component on the nut after the nut is assembled. If the two installation holes are misaligned, the anti-loosening component needs to be removed and the tightening degree needs to be adjusted again. The whole assembly process is relatively cumbersome. Summary of the Utility Model

The distance between the center of the threaded hole and the axis of the first locking member or the second locking member is greater than the distance between the inner arc wall near the center of the arc-shaped through groove and the axis of the first locking member or the second locking member and less than the distance between the outer arc wall far from the center of the arc-shaped through groove and the axis of the first locking member or the second locking member. The anti-loosening member is adjusted in position so that the arc-shaped through groove corresponds to the threaded hole, and the first locking member or the second locking member is clamped in such a way that at least one of the first protrusions or at least one of the second protrusions is clamped in at least one of the notches. The bolt passes through the arc-shaped through groove and is threadedly engaged with the threaded hole to press the anti-loosening member against the valve body.

4. The anti-loosening valve group according to claim 2 or 3, characterized in that, Two sets of the installation assemblies are provided for each group, and each anti-loosening member is detachably installed on the valve body through the two installation assemblies of one group.

5. The valve group for preventing loosening according to claim 2, wherein, The anti-loosening member further has a clamping space, and the notch forms the inner wall of the clamping space. The first locking member or the second locking member is clamped with the corresponding anti-loosening member in such a way that at least part of it is clamped in the clamping space of an anti-loosening member and at least one of the first protrusions or at least one of the second protrusions is clamped in at least one of the notches.

6. The anti-loosening valve group according to claim 5, characterized in that, The first locking member or the second locking member is surrounded by the corresponding anti-loosening member in such a way that it is placed in the corresponding clamping space.

7. The anti-loosening valve group according to claim 5, wherein The first locking member or the second locking member is semi-surrounded by the corresponding anti-loosening member in such a way that part of it is located in the corresponding clamping space.

8. The anti-loosening valve group according to any one of claims 5 to 7, characterized in that, A plurality of the first protrusions and the second protrusions are provided, and the plurality of first protrusions and the plurality of second protrusions are all arranged at intervals. A plurality of the notches are provided, and the plurality of notches are arranged at intervals. The anti-loosening member is adjusted so that the assembly structure corresponds to the installation structure, and the first locking member or the second locking member is clamped in such a way that at least one of the first protrusions or at least one of the second protrusions corresponds to any at least one of the plurality of notches.

9. The anti-loosening valve group according to claim 5, characterized in that The control component includes a coil and an iron core group. The locking component further includes a third locking member. The iron core group is sleeved on the valve body. The first locking member is sleeved on the iron core group and is threadedly connected to the valve body to press-fit the iron core group on the valve body. The coil is sleeved on the iron core group. The third locking member is threadedly connected to the iron core group and abuts against one end of the coil away from the first locking member. At least one third protrusion is formed on the outer periphery of the third locking member, and the size of the third protrusion is adapted to the size of the notch.

10. The anti-loosening valve group according to claim 9, characterized in that, The anti-loosening member includes two anti-loosening portions. The two anti-loosening portions are arranged side by side and each forms at least one of the notches and together form the clamping space. One of the anti-loosening portions of one of the anti-loosening members forms the assembly structure and is detachably mounted on the valve body through the mounting member. At least one of the notches formed in the corresponding anti-loosening portion corresponds to at least one of the first protrusions so that the first locking member is clamped by the corresponding anti-loosening portion. At least one of the notches corresponding to the other anti-loosening portion of the anti-loosening member corresponds to at least one of the third protrusions so that the third locking member is clamped by the corresponding anti-loosening portion.
