Description

Technical Field

[0001] The utility model relates to the technical field of fire valves, in particular to an inner buckle type fire valve with a rapid positioning function. Background Art

[0002] Valves are pipe accessories used to open and close pipes, control flow direction, and adjust and control the parameters (temperature, pressure, and flow) of the conveying medium. Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal, and radioactive media. Fire valves are a type of valve that are used to control the medium on industrial and building pipelines. They are composed of a valve body, an opening and closing mechanism, and a valve cover. During use, they can meet the firefighting work in the surrounding environment when there is a fire.

[0003] The patent document with publication number CN220060755U discloses an inward-clicking fire valve with a quick positioning function. By setting a positioning mechanism, when the spherical block rotates with the handle to a position where the valve body is fully closed or opened, the alarm can sound an alarm, thereby accurately locating the rotation position of the handle, assisting the operator to accurately and quickly determine whether the handle has been rotated to a specific position, avoiding the valve body from being not fully opened during use, affecting the water flow rate, and further affecting fire rescue, or increasing water and electricity consumption due to the handle not being rotated to a fully closed position when not in use.

[0004] However, in the process of implementing the above technical solution, it is found that the above technical solution has the following technical problems:

[0005] The existing inward-clicking fire valve with a quick positioning function is provided with a positioning mechanism. When the handle is rotated to control the valve body switch, an alarm is used to sound an alarm to confirm whether the positioning handle is rotated to a specific position. This is simple and convenient. However, in actual application, during firefighting and rescue, the fire alarm and the surrounding noise are relatively loud. The method of using an alarm to confirm the positioning effect is easily affected by environmental noise and has high limitations. Utility Model Content

[0006] In order to overcome the shortcomings of the existing inward-clicking fire valve with a quick positioning function, which is that the fire alarm and the surrounding noise are loud during fire rescue, and the method of using an alarm to confirm the positioning effect is easily affected by environmental noise and has high limitations, the embodiment of the present application provides an inward-clicking fire valve with a quick positioning function, by sleeved a marking structure on the outside of the control column, when the control handle is rotated to drive the marking structure to rotate synchronously, the marking ring on the marking structure drives the positioning ball head to move, and when one end of the positioning ball head slides out from the inside of the positioning ball groove, the positioning ball head pushes the sliding column to the top, so that one end of the marking rod extends from the inside of the marking ring, so that the rotation of the control handle can be judged according to whether one end of the marking rod protrudes from the surface of the marking ring. It is simple and efficient.

[0007] The technical solution adopted by the embodiment of the present application to solve the technical problem is:

[0008] An inward-buckled fire valve with a quick positioning function comprises a fire valve housing, an end cover and a marking structure, wherein the end cover is assembled and connected to the top of the fire valve housing;

[0009] The marking structure is arranged on the top of the end cover;

[0010] Wherein, the marking structure includes a marking ring, a marking rod is arranged inside the marking ring, a sliding column is processed at one end of the marking rod, a positioning ball head is processed at one end of the sliding column, and four positioning ball grooves are processed at the top of the end cover.

[0011] In a possible implementation, a switching ball head is provided inside the fire valve housing, a control column is processed on the top of the switching ball head, one end of the control column is assembled with a control handle, the control column passes through the center of the end cover, and is movably connected to the inside of the end cover.

[0012] In a possible implementation, four positioning ball grooves are equally spaced around the control column, one end of the positioning ball head is matched with the positioning ball groove, and one end surface of the marking rod is flush with the surface of the marking ring.

[0013] In a possible implementation, the marking ring moves with the control column on the top of the end cover, and the sliding column is slidably connected to the inside of the marking ring.

[0014] In a possible implementation, a receiving groove is processed at the bottom of the marking ring, a blocking cover is arranged inside the receiving groove, the blocking cover is connected and fixed to the marking ring by bolts, and the bolts are received and connected inside the receiving groove.

[0015] In a possible implementation, a support spring is sleeve-connected to the outside of the marking rod, and the support spring is disposed between the sliding column and the inner wall of the marking ring.

[0016] In a possible implementation, a gasket is sleeve-connected to the outside of one end of the control column, the top surface of the gasket fits with the bottom surface of the control handle, and the bottom surface of the control handle fits with the top surface of the marking ring.

[0017] In summary, the present invention includes at least one of the following beneficial technical effects:

[0018] 1. By sleeve-fitting the marking structure on the outside of the control column, when the control handle is turned, the marking structure is driven to rotate synchronously, so that the marking ring on the marking structure drives the positioning ball head to move, and when one end of the positioning ball head slides out from the inside of the positioning ball groove, the positioning ball head pushes the sliding column to the top, so that one end of the marking rod extends out from the inside of the marking ring, so that the rotation of the control handle can be judged according to whether one end of the marking rod protrudes from the surface of the marking ring. It is simple and efficient;

[0026] The technical solution in the embodiment of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows:

[0027] Embodiment 1:

[0028] This embodiment introduces a specific structure of an inward-facing fire valve with a quick positioning function. Figure 1-Figure 5 As shown, it includes a fire valve housing 4, an end cover 5 assembled and connected to the top of the fire valve housing 4, and a marking structure 3 arranged on the top of the end cover 5, the marking structure 3 includes a marking ring 301, a marking rod 302 is arranged inside the marking ring 301, a sliding column 304 is processed at one end of the marking rod 302, a positioning ball head 305 is processed at one end of the sliding column 304, and four positioning ball grooves 8 are processed on the top of the end cover 5;

[0029] like Figure 1 and Figure 2 As shown, a switching ball head 7 is arranged inside the fire valve housing 4, a control column 6 is processed on the top of the switching ball head 7, and a control handle 1 is assembled and connected to one end of the control column 6;

[0030] The control column 6 passes through the center of the end cover 5 and is movably connected to the inside of the end cover 5. When the control column 6 is rotated by the control handle 1 to drive the switching ball head 7 to switch the channel inside the fire valve housing 4, the control column 6 can be used to drive the marking structure 3 to rotate synchronously.

[0031] Secondly, in order to facilitate observation, control whether 1 is turned to the target position, such as Figure 4 and Figure 5 As shown, four positioning ball grooves 8 are equally spaced around the control column 6, and one end of the positioning ball head 305 is adapted to the positioning ball groove 8. When one end of the positioning ball head 305 is located inside the positioning ball groove 8, one end surface of the marking rod 302 is flush with the surface of the marking ring 301;

[0032] At the same time, when the marking ring 301 rotates with the control column 6, so that one end of the positioning ball head 305 slides out from the inside of the positioning ball groove 8, the positioning ball head 305 drives the sliding column 304 to slide inside the marking ring 301, so that one end of the marking rod 302 extends out from the inside of the marking ring 301, which is conducive to judging the rotation of the control handle 1 according to whether one end of the marking rod 302 protrudes from the surface of the marking ring 301.

[0033] Furthermore, in order to facilitate the storage of the slide post 304 inside the marking ring 301, the marking rod 302, the slide post 304 and the positioning ball head 305 are restricted from being separated from the inside of the marking ring 301. Figure 5 As shown, a receiving groove 9 is processed at the bottom of the marking ring 301, and a blocking cover 306 is arranged inside the storing groove 9. After the blocking cover 306 is connected and fixed to the marking ring 301 by bolts, the marking rod 302, the sliding column 304 and the positioning ball head 305 can be stored inside the marking ring 301;

[0034] At the same time, the bolts for connecting the blocking cover 306 and the marking ring 301 are received and connected inside the receiving groove 9, which can prevent the marking ring 301 from interfering with the surface of the end cover 5 when rotating with the control column 6.

[0035] By adopting the above technical solution:

[0036] The above design is to sleeve the marking structure 3 on the outside of the control column 6. When the control handle 1 is rotated to make the control column 6 drive the switching ball head 7 to switch the channel inside the fire valve housing 4, the control column 6 is used to drive the marking structure 3 to rotate synchronously, so that the marking ring 301 on the marking structure 3 drives the positioning ball head 305 to move. When one end of the positioning ball head 305 slides out from the inside of the positioning ball groove 8, the positioning ball head 305 drives the sliding column 304 to the top to slide inside the marking ring 301, so that one end of the marking rod 302 extends from the inside of the marking ring 301. This is conducive to judging the rotation status of the control handle 1 based on whether one end of the marking rod 302 protrudes from the surface of the marking ring 301. The control handle 1 can be controlled to rotate to the target position without being affected by the fire rescue environment. It is simple and quick.

[0037] Embodiment 2:

[0038] Based on Example 1, this example introduces the specific structure of the marking structure 3, where the outer sleeve of the marking rod 302 is connected with a supporting spring 303;

[0039] Among them, by arranging the support spring 303 between the sliding column 304 and the inner wall of the marking ring 301, when the rotating control column 6 drives the marking ring 301 to rotate, so that one end of the positioning ball head 305 slides out from the inside of the positioning ball groove 8, the positioning ball head 305 can be used to push the positioning ball head 305 to move toward the top, thereby compressing the support spring 303;

[0040] At the same time, when one end of the positioning ball head 305 is located inside the positioning ball groove 8, resistance can be added to limit the movement of the marking ring 301 on the top of the end cover 5 without external force;

[0041] Secondly, in order to ensure that the bottom end of the marking ring 301 fits with the top end of the end cap 5, and one end of the positioning ball head 305 falls inside the positioning ball groove 8, so as to increase the resistance of the marking ring 301 to the movement on the top of the end cap 5, as shown in FIG. Figure 4 As shown, a gasket ring 2 is sleeve-connected to the outside of one end of the control column 6. By making the top surface of the gasket ring 2 fit with the bottom surface of the control handle 1, and making the bottom surface of the control handle 1 fit with the top surface of the marking ring 301, the bottom end of the marking ring 301 can fit with the top end of the end cover 5 after the control handle 1 is assembled and fixed to one end of the control column 6.

[0042] By adopting the above technical solution:

[0043] The above design arranges a gasket 2 on the outside of the control column 6 so that the gasket 2 is supported between the marking ring 301 and the control handle 1, and sleeves a support spring 303 on the outside of the marking rod 302 so that the support spring 303 is supported between the top inner wall of the marking ring 301 and the sliding column 304. When the rotating control column 6 drives the marking ring 301 to rotate, so that one end of the positioning ball head 305 slides out from the inside of the positioning ball groove 8, the positioning ball head 305 can be used to push the positioning ball head 305 to move toward the top, compressing the support spring 303, so that one end of the marking rod 302 can be extended from the inside of the marking ring 301 for observation by the user.

[0044] At the same time, when one end of the positioning ball head 305 is located inside the positioning ball groove 8, the marking ring 301 can be restricted from moving on the top of the end cover 5 without external force by adding resistance, ensuring that the control handle 1 is always at a certain angle in a static state.

[0045] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
