Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a valve capable of arbitrarily adjusting the direction of a pressure gauge. Background Art

[0002] In the current industry, the valve part that can adjust the direction of the pressure gauge arbitrarily needs to install the pressure gauge. The common installation method of the pressure gauge is: the valve body is provided with a mounting hole for the pressure gauge, the mounting hole is provided with an internal thread, the end of the pressure gauge is provided with an external thread, and the external thread of the pressure gauge is screwed and tightened with the internal thread of the mounting hole to complete the assembly. However, due to the uncertainty of the thread rotation direction, after the pressure gauge is installed, the direction of the pressure gauge dial is random and uncontrollable, which affects the reading and spatial layout of the pressure gauge.

[0003] In order to solve the above problems, patent CN220452902U discloses a 360° adjustable valve for a pressure gauge, in which a first compression sleeve is mounted on the surface connection part and screwed to the inner wall of the connecting pipe, and a second compression sleeve is screwed to the outside of the surface connection part and placed inside the connecting pipe, thereby limiting the first compression sleeve and realizing the mutual rotation between the first compression sleeve and the second compression sleeve. Since the inner hole of the first compression sleeve and the outer wall of the second compression sleeve are both smooth, the pressure gauge can be rotated 360° until it is adjusted to the angle required by the user. This method has the following problems: Since the first compression sleeve and the pressure gauge are matched with a smooth inner wall, and the second compression sleeve and the connecting pipe are also matched with a smooth inner wall, there will inevitably be a gap between the smooth inner walls, so this method may cause the pressure gauge to shake slightly, affecting normal use. Secondly, the prior art uses two compression sleeves, with many structural parts and cumbersome assembly.

[0004] Therefore, it is urgent to provide a valve that can arbitrarily adjust the direction of the pressure gauge to solve the above problems. Utility Model Content

[0018] The utility model provides a valve capable of arbitrarily adjusting the direction of a pressure gauge. When installing the pressure gauge, firstly, a connecting piece is threadedly sleeved on the outside of the pressure gauge, and the connecting piece is rotated to an unlocked position, and then the pressure gauge is plugged into the mounting hole. At this time, the connecting piece is located outside the mounting hole, and the pressure gauge can rotate freely in the mounting hole.

[0033] In the description of this embodiment, the terms "upper", "lower", "right", etc., are based on the directions or positions shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0034] like Figure 1 and Figure 2As shown, this embodiment provides a valve that can adjust the direction of the pressure gauge at will. The valve can be a pressure reducing valve, a ball valve, etc. This embodiment is described by taking the valve as a pressure reducing valve as an example. Specifically, the pressure reducing valve includes a valve body 10, a valve cover 50 and a pressure reducing assembly 40. The valve cover 50 is threadedly connected to the upper end of the valve body 10 to form a closed valve cavity 14. The pressure reducing assembly 40 is arranged in the valve cavity 14. The left and right ends of the valve body 10 are respectively provided with an inlet channel 12 and an outlet channel 13. The inlet channel 12 and the outlet channel 13 are used to connect to external pipelines. The valve cavity 14 is respectively connected to the inlet channel 12 and the outlet channel 13, and the valve cavity 14 is inclined relative to the inlet channel 12 and the outlet channel 13. The pressure reducing assembly 40 can cut off or connect the water inlet channel 12 and the water outlet channel 13 by moving along the axial direction in the valve cavity 14, thereby realizing the cutoff or flow of the fluid, thereby realizing the closing or opening of the pressure reducing valve. When the pressure reducing valve is in the open state, the pressure reducing assembly 40 can realize the pressure reducing and stabilizing effect. Among them, the specific structure and working principle of the pressure reducing assembly 40 are all existing technologies and will not be repeated here.

[0035] To detect fluid pressure, such as Figure 1 and Figure 2 As shown, the pressure reducing valve also includes a pressure gauge 20, an assembly port 11 is provided on the valve body 10, a mounting hole 111 is provided in the assembly port 11, the pressure gauge 20 is partially inserted in the mounting hole 111, and a connecting hole 15 is also provided on the valve body 10, the connecting hole 15 is used to connect the mounting hole 111 and the water outlet channel 13, so that the pressure gauge 20 can detect the outlet water pressure in the water outlet channel 13.

[0036] like Figure 2 and Figure 3 As shown, in order to realize the installation of the pressure gauge 20, the pressure reducing valve further includes a connecting member 30, which is threadedly connected to the outside of the pressure gauge 20. By screwing the connecting member 30 along the thread on the pressure gauge 20, the connecting member 30 can be switched between the unlocked position and the locked position; Figure 2 As shown, in the unlocked position, the connector 30 is rotated outside the mounting hole 111, and the pressure gauge 20 can rotate freely in the mounting hole 111; Figure 3 As shown, in the locking position, the connecting member 30 is screwed into the mounting hole 111 and is threadedly connected with the mounting hole 111 .

[0037] When installing the pressure gauge 20, first thread the connector 30 onto the outside of the pressure gauge 20, and screw the connector 30 until it is as shown in the figure. Figure 2The pressure gauge 20 is then inserted into the mounting hole 111. At this time, the connector 30 is located outside the mounting hole 111, and the pressure gauge 20 can rotate freely in the mounting hole 111. The direction of the pressure gauge 20 can be adjusted to the required direction, and then the connector 30 is screwed so that the connector 30 is screwed into the mounting hole 111 along the thread on the pressure gauge 20 and is threadedly connected with the mounting hole 111, so that the connector 30 is in the position shown in FIG. Figure 3 The locking position shown in the figure, at this time, the inner wall of the connecting piece 30 and the pressure gauge 20 are threadedly connected, and the outer wall of the connecting piece 30 and the mounting hole 111 are also threadedly connected, thereby achieving a stable connection of the pressure gauge 20 and preventing the pressure gauge 20 from shaking. When the direction of the pressure gauge 20 needs to be adjusted, the connecting piece 30 can be screwed back along the threads on the pressure gauge 20 to the position shown in the figure. Figure 2 The unlocked position shown in FIG. 1 is used to disconnect the connector 30 from the mounting hole 111. The pressure gauge 20 can now rotate freely. The pressure gauge 20 can then be adjusted to the desired orientation. The connector 30 can then be rotated back to the desired orientation. Figure 3 The locking position shown, therefore, through the above settings, the orientation of the pressure gauge 20 can be adjusted arbitrarily so that the pressure gauge 20 meets different reading requirements and spatial layouts, and only one connector 30 is required to complete the installation of the pressure gauge 20, with fewer structural parts and convenient and quick assembly.

[0038] like Figure 2 and Figure 3 As shown, a seal 60 is provided between the pressure gauge 20 and the bottom of the mounting hole 111, thereby forming a good sealing effect to prevent liquid leakage. The seal 60 is an O-ring. Before the pressure gauge 20 is inserted into the mounting hole 111, the seal 60 is first placed at the bottom of the mounting hole 111, and then the pressure gauge 20 is inserted into the mounting hole 111. The pressure gauge 20 directly presses the seal 60 to achieve a sealing effect.

[0039] like Figure 5 and Figure 6 As shown, the pressure gauge 20 includes a gauge head 21 and a mounting portion 22 connected to each other, the mounting portion 22 is inserted into the mounting hole 111, and the connecting member 30 is threadedly connected to the outside of the mounting portion 22. Specifically, the outer wall of the mounting portion 22 is provided with a second outer thread 221, and the inner wall of the connecting member 30 is provided with a second inner thread 33 that matches the second outer thread 221. Through the threaded connection between the second outer thread 221 and the second inner thread 33, the connecting member 30 is stably sleeved on the mounting portion 22.

[0040] Combination Figure 3 , Figure 4 and Figure 6The mounting hole 111 includes a first hole 1111 and a second hole 1112 which are coaxially connected. The first hole 1111 is closer to the meter head 21. The aperture of the first hole 1111 is larger than the aperture of the second hole 1112. The mounting portion 22 is plugged into the first hole 1111 and the second hole 1112. The hole wall of the first hole 1111 is provided with a first internal thread 1113. The outer wall of the connecting piece 30 is provided with a first external thread 321 which cooperates with the first internal thread 1113. The connecting piece 30 is stably connected to the mounting hole 111 through the threaded connection between the first external thread 321 and the first internal thread 1113. The mounting portion 22 is matched with the second hole 1112, the free end of the mounting portion 22 is inserted into the second hole 1112 and pressed against the sealing member 60, the middle portion of the mounting portion 22 is located in the first hole 1111 and is fixedly connected to the first hole 1111 through the connecting member 30, and the rest of the mounting portion 22 extends out of the mounting hole 111. This type of mounting hole 111 can reduce the height of the pressure gauge 20 during installation, save installation space, and avoid interference with other valves. The cooperation between the second hole 1112 and the mounting portion 22 can also play a certain role in limiting the mounting portion 22, and try to avoid shaking of the pressure gauge 20.

[0041] In an optional embodiment, the wall of the second hole 1112 is a smooth surface. By setting the wall of the second hole 1112 to a smooth surface, the friction can be reduced, and when the connecting member 30 is in the unlocked position, the pressure gauge 20 can be freely rotated 360 degrees until it is adjusted to the angle required by the user, and the rotation is smooth and the adjustment is convenient.

[0042] Furthermore, the axial height of the connecting member 30 is less than the length of the second external thread 221 on the mounting portion 22. This arrangement allows the connecting member 30 to have sufficient screwing space on the mounting portion 22, so that the connecting member 30 can switch between the unlocking position and the locking position along the second external thread 221.

[0043] Furthermore, the depth of the mounting hole 111 is less than the axial length of the mounting portion 22. This arrangement ensures that after the mounting portion 22 of the pressure gauge 20 is inserted into the mounting hole 111, the bottom of the mounting portion 22 can contact and press the seal 60 in the second hole 1112 to achieve a sealing effect.

[0044] like Figure 4 As shown, a step surface 1114 is formed at the connection between the first hole 1111 and the second hole 1112, and one end of the connector 30 can abut against the step surface 1114. The step surface 1114 can limit the connector 30. When the connector 30 abuts against the step surface 1114 during the process of screwing the connector 30, it means that the connector 30 is installed in place.

[0045] In an optional embodiment, if Figure 1 and Figure 5As shown, a second screwing portion 23 is further provided between the gauge head 21 and the mounting portion 22, and a wrench is processed on the outer circumference of the second screwing portion 23, and the shape of the wrench is preferably a regular hexagon. This form of the second screwing portion 23 is convenient for cooperation with operating tools such as a wrench, so that the pressure gauge 20 can be rotated by the tool, and force can be applied conveniently, thereby achieving the purpose of labor saving.

[0046] In an optional embodiment, if Figure 2 , Figure 3 and Figure 6 As shown, the connecting member 30 includes a first screwing portion 31 and a threaded portion 32 connected to each other. The first screwing portion 31 is closer to the meter head 21. A first external thread 321 is provided on the outer wall of the threaded portion 32. The threaded portion 32 is threadedly engaged with the first internal thread 1113 on the hole wall of the first hole 1111 through its first external thread 321, thereby connecting the connecting member 30 to the mounting hole 111. The connecting member 30 can be conveniently screwed through the first screwing portion 31.

[0047] In an optional embodiment, if Figure 6 As shown, the outer diameter of the first screwing portion 31 is greater than the outer diameter of the threaded portion 32. This arrangement makes it easier to screw the connector 30 through the first screwing portion 31, making the operation easier and more labor-saving.

[0048] In an optional embodiment, if Figure 1 As shown, the outer peripheral surface of the first screwing portion 31 is processed with a wrench, and the shape of the wrench is preferably a regular hexagon. This form of the first screwing portion 31 is convenient for cooperation with operating tools such as wrenches, so that it is convenient to screw the connecting member 30 through the tool, which is convenient for applying force and achieving the purpose of labor saving.

[0049] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
