Description

Technical Field

[0001] The present application relates to the technical field of valve bodies, and in particular to a W-shaped ball valve. Background Art

[0002] Ball valves, as important components mainly used for cutting off, distributing, and changing the flow direction of media in pipelines, are widely used in oil and gas transportation pipelines. Due to the characteristics of small fluid resistance, fast opening and closing speed, and simple operation of ball valves, they are widely used in industries such as petroleum, natural gas, chemical industry, heating, and power stations. The sealing of a ball valve is formed by the preset pre-tightening force between the ball and the valve seat plus the acting force caused by the liquid pressure on the valve seat sealing surface.

[0003] When some ball valves are in use, an electronic drive is used for remote opening and closing or electronic opening and closing. However, when connecting these drives, due to the uniform style of the valve stem of the ball valve, it is impossible to accurately understand the opening and closing state of the valve core inside the ball valve, which affects the installation accuracy. It is necessary to test after installation to ensure the accurate installation state of the drive and the valve stem. Summary of the Invention

[0004] In order to improve the above problems, the present application provides a W-shaped ball valve.

[0005] The W-shaped ball valve provided by the present application adopts the following technical solutions:

[0006] A W-shaped ball valve includes a valve body and a valve seat; the valve body is installed on the valve seat and is communicated with the valve seat; a spherical valve core is arranged in the valve seat, the spherical valve core is connected with a valve stem, the valve stem penetrates through the valve seat and the valve body and extends outwards, and a drive is externally connected after extension; a positioning groove is opened on the top surface of the valve stem, and the opening direction of the positioning groove is consistent with the opening and closing direction of the spherical valve core; an installation marking groove for inserting the drive is opened on the side wall of the valve stem.

[0007] By adopting the above technical solutions, when installing the drive, the drive is inserted into the installation marking groove, so that the drive can be accurately installed on the valve stem. At the same time, the position of the spherical valve core is determined by the positioning groove on the valve stem, and the installation position of the drive is determined by the installation marking groove, so as to achieve the effect of quickly, conveniently, and accurately installing the drive on the W-shaped ball valve.

[0008] Optionally, the positioning groove is a straight groove.

[0009] By adopting the above technical solutions, the straight groove can more intuitively observe the opening and closing state of the spherical valve core.

[0010] Optionally, two marking lights are further arranged in the valve stem, and are respectively embedded in the side walls on both sides of the installation marking groove, and a sensor is embedded at the bottom of the installation marking groove.

[0011] By adopting the above technical solution, the marker light is used to judge the accuracy of the connection status when the driver is connected to the valve stem. When the connection between the driver and the valve stem is stable, the driver contacts the sensor, thereby turning on the marker light to indicate that the current connection is an accurate connection.

[0012] Optionally, a side groove wall of the installation mark groove is paved with a transparent portion, and the mark light is located in the transparent portion.

[0013] By adopting the above technical solution, when the marker light is on, the light can shine out of the driver through the transparent part, thereby making the light more eye-catching and allowing the user to more intuitively observe the connection between the driver and the valve stem.

[0014] Optionally, the transparent portion passes through the installation mark groove and extends to the outer wall of the valve stem.

[0015] By adopting the above technical solution, the transparent part is no longer limited to the installation mark groove, but extends to the outer wall of the valve stem. Even when the driver is installed on the valve stem to cover the light, the light can still be observed through the transparent part extending to the outer wall of the valve cover, further improving the significance of observing the light.

[0016] Optionally, a reflective sheet is provided between the transparent portion and the groove wall of the installation mark groove.

[0017] By adopting the above technical solution, when the marker light is on, the light can be reflected in the installation marker groove through the reflective sheet, which can intensify the light and further improve the light reflection, making it easier for the user to observe the light.

[0018] Optionally, the transparent part is provided with a power connection piece, which is divided into a positive pole and a negative pole and is respectively located on the transparent part on both side walls of the installation mark groove, and the plug-in end of the driver is connected to the power connection piece.

[0019] By adopting the above technical solution, when the plug-in end of the driver is inserted into the installation mark slot, as the installation plug block is continuously inserted, the power connection part contacts the positive and negative poles, thereby connecting the positive and negative poles to automatically turn on the mark light. This method can automatically turn on the mark light without using a sensor.

[0020] Optionally, the distance from the end of the power connection plate to the bottom of the installation mark groove is consistent with the height of the power connection part.

[0021] By adopting the above technical solution, when the power connection part moves to the bottom of the marking slot, the power connection part can just leave the contact range of the power connection sheet, so that the marker light loses the connection between the positive and negative poles and is turned off, thereby achieving the effect of automatically closing the marker light.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. When installing the drive, the drive is inserted into the installation mark slot for alignment, so that the drive can be accurately installed on the valve stem. At the same time, the positioning slot on the valve stem is used to determine the position of the spherical valve core, and then the installation position of the drive is determined through the installation mark slot, so as to achieve the effect of quickly, conveniently and accurately installing the drive on the W-ball valve;

[0024] 2. The one-word slot can more intuitively observe the opening and closing state of the spherical valve core;

[0025] 3. The marking lamp is used to provide a judgment on the accuracy of the connection state when the drive is connected to the valve stem. When the drive is stably connected to the valve stem, the drive contacts the sensor, thereby turning on the marking lamp to indicate that the current connection is an accurate connection;

[0026] 4. When the marking lamp is on, the light can shine through the transparent part to illuminate the drive, making the light more eye-catching and enabling the user to more intuitively observe the connection situation between the drive and the valve stem. Description of the Drawings

[0037] The following will further describe the present application in detail Figure 1 - with reference to the Figure 4 accompanying drawings.

[0038] An embodiment of the present application discloses a W-type ball valve.

[0039] The W-type ball valve not only has a simple structure and good sealing performance, but also has a small volume, light weight, less material consumption, small installation size within a certain nominal size range, and small driving torque, simple operation, and easy to achieve rapid opening and closing. In addition to using a rotating handle to open and close, the existing W-type ball valve also uses an electronic driver 5, which can achieve remote control of opening and closing. However, when connecting these drivers 5, due to the uniform style of the valve stem 4 of the W-type ball valve, it is impossible to accurately understand the opening and closing state of the valve core inside the ball valve. If the driver 5 is installed in the reverse direction, it is impossible to achieve opening and closing, affecting the installation accuracy. Therefore, it is necessary to conduct tests after installation to ensure the accurate installation state of the driver 5 and the valve stem 4. In order to improve the installation accuracy and provide a more convenient installation, an application of an W-type ball valve of the present application is therefore used.

[0040] Reference Figure 1 and Figure 2 As shown, an W-type ball valve includes a valve body 1 and a valve seat 2; the valve body 1 is installed on the valve seat 2 and is communicated with the valve seat 2. An O-ring and a sealing seat are also provided between the valve seat 2 and the valve body 1. The O-ring cooperates with structures such as a valve cover and a sealing gasket to seal the connection point between the valve body 1 and the valve seat 2, avoiding phenomena such as water leakage.

[0041] A spherical valve core 3 is provided inside the valve seat 2. The spherical valve core 3 is connected to a valve stem 4. A composite bearing is also provided on the valve body 1. The valve stem 4 is movably connected to the composite bearing to provide support for the valve stem 4, enabling the valve stem 4 to rotate stably. When the valve stem 4 rotates, it can drive the ball valve to rotate along the inner cavity of the valve seat 2 to switch the communication state inside the valve seat 2.

[0042] The valve stem 4 penetrates through the valve seat 2 and the valve body 1 and extends outward. After extension, it is externally connected to a driver 5. The driver 5 is electrically connected to the controller in the background, enabling the background to send control signals to control the driver 5 to control the rotation of the valve stem 4 and switch the opening and closing state of the spherical valve core 3.

[0043] A positioning groove 41 is opened on the top surface of the valve stem 4. The opening direction of the positioning groove 41 is consistent with the opening and closing direction of the spherical valve core 3. By using the opening direction of the positioning groove 41, the opening and closing state of the spherical valve core 3, such as the open state or the closed state, can be intuitively understood.

[0044] An installation marking groove 42 for inserting the driver 5 is opened on the side wall of the valve stem 4. The installation marking groove 42 is unique, that is, there is only one installation marking groove 42 on the entire side surface of the valve stem 4. When installing the driver 5, an installation insertion block corresponding to the installation marking groove 42 is provided on the driver 5. The installation insertion block is aligned with the installation marking groove 42 for insertion, enabling the driver 5 to be accurately installed on the valve stem 4. At the same time, the position of the spherical valve core 3 is determined by the positioning groove 41 on the valve stem 4, and the installation position of the driver 5 is determined by the installation marking groove 42, so as to achieve the function of quickly, conveniently and accurately installing the driver 5 on the W-type ball valve.

[0045] For further reference, Figure 1 As shown, the positioning groove 41 can be a straight groove, and the straight groove can more intuitively observe the opening and closing state of the spherical valve core 3. For example, the end of the straight groove corresponds to the end of the spherical valve core 3. When the straight groove is rotated to be on the same axis as the valve seat 2, the spherical valve core 3 closes the valve seat 2. When the straight groove is rotated to be tangent to the axis of the valve seat 2, such as in the shape of the number "1", the spherical valve core 3 opens the valve seat 2, thereby realizing the function of intuitively determining the opening and closing state of the spherical valve core 3.

[0046] In some embodiments, reference Figure 3 As shown, a marker light 43 is also provided in the valve stem 4. The marker light 43 is used to judge the accuracy of the connection state when the driver 5 is connected to the valve stem 4. The marker light 43 can be an LED light and has a battery inside. There are two marker lights 43, which are respectively embedded in the two side walls of the installation mark groove 42. The marker light 43 can be turned on and off intermittently, that is, after starting, it is lit within a unit time. After exceeding the set unit time, the marker light 43 is automatically turned off.

[0047] A sensor 421 is embedded at the bottom of the installation mark groove 42. The sensor 421 can be a pressure sensor 421. The mark light 43 is electrically connected to the pressure sensor 421. When the installation plug of the driver 5 is inserted into the installation mark groove 42 and inserted to the correct position, the installation plug contacts the sensor 421, thereby turning on the mark light 43. The flashing light of the mark light 43 reflects the driver 5, so that the user can intuitively understand that the driver 5 is accurately connected to the valve stem 4.

[0048] For further reference, Figure 3 As shown, the side groove wall of the installation mark groove 42 is paved with a transparent portion 44, and the mark light 43 is located in the transparent portion 44. The transparent portion 44 can be made of a transparent plastic plate, and the transparent plastic plate can be light-transmissive. When the mark light 43 is on, the light can pass through the transparent portion 44 to illuminate the driver 5, thereby making the light more eye-catching, allowing the user to more intuitively observe the accurate connection between the driver 5 and the valve stem 4.

[0049] Further, refer to Figure 4 As shown, the transparent portion 44 passes through the installation mark groove 42 and extends to the outer wall of the valve stem 4. The transparent portion 44 is no longer limited to being located in the installation mark groove 42, but extends to the outer wall of the valve stem 4. Even when the driver 5 is installed on the valve stem 4 to cover the light, the light can still be observed through the transparent portion 44 extending to the outer wall of the valve cover, further improving the significance of observing the light.

[0050] Further, refer to Figure 4As shown, a reflective sheet 45 is provided between the transparent portion 44 and the groove wall of the installation mark groove 42. The reflective sheet 45 can be made of a metal sheet or a tin foil sheet, which has a reflective property, so that when the marker light 43 is on, the light can be reflected in the installation mark groove 42 through the reflective sheet 45, which can intensify the light and further improve the light reflection, making it easier for the user to observe the light.

[0051] In some embodiments, reference Figure 4 As shown, the transparent portion 44 is provided with a power connection sheet 46, which is divided into a positive pole and a negative pole, and is respectively located on the transparent portion 44 on both side walls of the installation mark slot 42. The power connection sheet 46 is made of metal, and a metal connection wire can also be used. When installed on the transparent portions 44 on both sides, the positive and negative power connection sheets 46 on both sides are not connected, so the mark light 43 cannot be turned on.

[0052] The plug-in end of the driver 5, that is, the mounting plug, is connected with a power connection part 51, which can be a metal power connection block. When the mounting plug of the driver 5 is inserted into the mounting mark slot 42, as the mounting plug is continuously inserted, the power connection part 51 contacts the positive and negative poles of the power connection pieces 46, thereby connecting the positive and negative poles of the power connection pieces 46 to automatically turn on the mark light 43. This method can automatically turn on the mark light 43 without using the sensor 421.

[0053] Furthermore, the distance between the end of the power connection piece 46 and the bottom of the installation mark slot 42 is consistent with the height of the power connection part 51, so that when the power connection part 51 moves to the bottom of the installation mark slot 42 or is positioned accurately, the power connection part 51 can just leave the contact range of the power connection piece 46, so that the marker light 43 loses the connection between the positive and negative poles and is turned off, thereby achieving the effect of automatically closing the marker light 43.

[0054] Among them, if a sensor 421 is provided, the installation plug contacts the sensor 421 to send an electrical signal to the background, and the background data can be used to accurately understand whether the driver 5 and the valve stem 4 are installed correctly. At the same time, the marker light 43 is turned on and off when the power connection part 51 contacts the power connection piece 46, which can provide multiple verifications of the accuracy and stability of the installation in two ways.

[0055] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
