Description

Technical Field

[0001] This utility model relates to the field of ball valve technology, specifically a water pipe ball valve with a sealing groove. Background Technology

[0002] A liquid valve is a device used to control the flow of liquids. It plays an important role in both industrial and civil fields. Its main function is to open or close liquid pipelines and regulate parameters such as the flow rate and pressure of liquids. Structurally, a liquid valve mainly consists of a valve body, valve cover, valve seat, opening and closing parts, drive mechanism, seals and fasteners. Its working principle is to use the drive mechanism to make the opening and closing parts move up and down, slide, swing or rotate, thereby changing the size of the flow channel area to control the liquid.

[0003] According to the search results, Chinese patent document, publication number: CN 208058002 U, discloses a ball valve. This utility model discloses a ball valve that solves the problem of easy misoperation of current ball valves. The key technical point of the ball valve is that it includes a valve body, a valve core installed in the valve body, and a control valve stem installed on the valve core. It also includes a handle assembly installed on the control valve stem. The handle assembly includes a rotating plate for adjusting the rotation of the control valve stem and a locking plate for restricting the rotation of the control valve stem. The valve body has a limiting post. The locking plate has a limiting through hole for the limiting post to be inserted and a disengagement through hole for the control valve stem to be inserted and restricting the rotation of the control valve stem. The ball valve has a handle assembly that can prevent misoperation and improve the safety performance of the ball valve.

[0004] The aforementioned device lacks a sealing mechanism at both ends, requiring the use of waterproof tape to wrap around both ends of the valve body when connecting to a pipeline. This is done to prevent water leakage due to insufficient sealing. However, this temporary measure may age and detach after prolonged use, failing to maintain a consistent and effective seal. Furthermore, improper wrapping can easily create gaps or uneven surfaces in the tape, providing a pathway for water leakage. Therefore, we provide a water pipe ball valve with a sealing groove. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a water pipe ball valve with a sealing groove.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a water pipe ball valve with a sealing groove, comprising a valve body, a spherical valve rotatably connected to the center of the valve body, and a through hole opened in the center of the spherical valve; a central shaft rotatably connected to the top of the valve body, and a hexagonal valve fixedly connected to the center of the top surface of the central shaft; multiple ports movably connected to both ends of the valve body, and one side of the outer wall of the port tightly fitting against the outer wall of one end of the valve body; multiple positioning pins fixedly connected to one side of the outer wall of the port; multiple mounting grooves opened on both sides of the port; and multiple threaded holes opened on both sides of the valve body, with mounting bolts rotatably connected to the center of the threaded holes.

[0007] As described above, the spherical valve has a perfectly circular shape, and the outer wall of the top of the spherical valve is fixedly connected to the outer wall of the bottom of the central shaft.

[0008] As described above, the outer wall of one end of the central shaft is connected through to the top of the valve body cavity, and the center of the outer wall of the central shaft is rotatably connected to the center of the valve body cavity.

[0009] As described above, one end of the outer wall of the positioning pin is connected through to one side of the outer wall of the valve body, and the outer wall of the positioning pin is slidably connected to one side of the inner wall of the valve body.

[0010] As mentioned above, sealing grooves are provided on the outer walls of both ends of the valve body and the outer walls of the ports, and sealing rings are fitted onto the outer walls of the sealing grooves.

[0011] As described above, one side of the outer wall of the mounting bolt is in close contact with the inner wall of the mounting groove, and the diameter of the thread of the mounting bolt is smaller than the inner diameter of the mounting groove. One end of the outer wall of the mounting bolt is connected through the center of the threaded hole, and one end of the outer wall of the mounting bolt is rotatably connected to the inside of the threaded hole through the thread.

[0012] Compared with existing technologies, this water pipe ball valve with a sealing groove has the following advantages:

[0013] I. This utility model, by rotating the hexagonal valve to drive the central shaft and the ball valve to rotate at the center inside the valve body, can adjust the flow rate of water inside the valve body by changing the angle of the through hole according to actual needs.

[0014] Second, this utility model, by opening multiple sealing grooves on the outer wall of the valve body and the outer wall of the port, allows installers to quickly install sealing rings at both ends of the valve body before connecting the device to the pipeline. By replacing the tape with sealing rings, the sealing rings can effectively fill gaps and ensure the sealing of the connection, greatly reducing the risk of water seepage and leakage. At the same time, it is more convenient for installers to operate, eliminating the need for time-consuming and laborious wrapping of tape, improving installation efficiency, and reducing sealing problems caused by improper operation.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1-5As shown, this utility model provides a technical solution: a water pipe ball valve with a sealing groove, including a valve body 1, a ball valve 2 rotatably connected to the center of the valve body 1, and a through hole 201 opened in the center of the ball valve 2, a central shaft 202 rotatably connected to the top of the valve body 1, and a hexagonal valve 203 fixedly connected to the center of the top surface of the central shaft 202, multiple ports 3 movably connected to both ends of the valve body 1, and one side of the outer wall of the port 3 tightly fitting with one end of the outer wall of the valve body 1, and multiple positioning pins 301 fixedly connected to one side of the outer wall of the port 3, and multiple mounting grooves 302 opened on both sides of the port 3, and multiple threaded holes 303 opened on both sides of the valve body 1, and mounting bolts 304 rotatably connected to the center of the threaded holes 303.

[0024] By rotating the hexagonal valve 203, the central shaft 202 and the ball valve 2 rotate at the center inside the valve body 1, changing the angle of the through hole 201. By opening multiple sealing grooves 305 on the outer wall of the valve body 1 and the outer wall of the port 3, the installer can quickly install the sealing ring 306 at both ends of the valve body 1 before connecting the device to the pipeline. The sealing ring 306 replaces the tape, and because the sealing ring 306 can effectively fill the gaps, it ensures the sealing of the connection, greatly reducing the risk of water seepage and leakage. At the same time, the installation is more convenient for the installer, eliminating the need for time-consuming and laborious wrapping of tape, improving installation efficiency, and reducing sealing problems caused by improper operation.

[0025] like Figure 3 As shown, the ball valve 2 is circular in shape, and the outer wall of the top of the ball valve 2 is fixedly connected to the outer wall of the bottom of the central shaft 202, so that the device can drive the ball valve 2 to rotate by rotating the central shaft 202.

[0026] One end of the outer wall of the central shaft 202 is connected through to the top of the inner cavity of the valve body 1, and the center of the outer wall of the central shaft 202 is rotatably connected to the center of the inner cavity of the valve body 1, so that the central shaft 202 can rotate smoothly inside the valve body 1.

[0027] like Figure 1-5 As shown, the outer wall of one end of the positioning pin 301 is connected through to one side of the outer wall of the valve body 1, and the outer wall of the positioning pin 301 is slidably connected to one side of the inside of the valve body 1. The positioning pin 301 is used to determine and restrict the positional relationship between the valve body 1 and the port 3.

[0028] Sealing grooves 305 are provided on the outer walls of both ends of valve body 1 and the outer wall of port 3, and sealing rings 306 are fitted on the outer walls of sealing grooves 305. By simultaneously providing sealing grooves 305 on the outer walls of both ends of valve body 1 and the outer walls of port 3, operators can more conveniently and quickly fit the sealing rings 306 onto the outer walls of valve body 1.

[0029] One side of the outer wall of the mounting bolt 304 is tightly fitted to the inner wall of the mounting groove 302, and the diameter of the thread of the mounting bolt 304 is smaller than the inner diameter of the mounting groove 302. Since the inner diameter of the mounting groove 302 is larger than the outer diameter of the mounting bolt 304, the mounting bolt 304 can rotate or move freely inside the mounting groove 302 without being restricted by the outer wall thread. However, when the outer wall of the mounting bolt 304 is fitted to the inner wall of the mounting groove 302, it rotates and inserts into the threaded hole 303, causing the drive port 3 to be tightly fitted to the outer wall of the valve body 1.

[0030] One end of the mounting bolt 304 is connected through the outer wall to the center of the threaded hole 303, and one end of the outer wall of the mounting bolt 304 is rotatably connected to the inside of the threaded hole 303 through the thread. The mounting bolt 304 can be inserted into the inside of the threaded hole 303 by rotating the outer wall thread.

[0031] Working principle: By rotating the hexagonal valve 203, the central shaft 202 and the ball valve 2 are rotated, changing the angle of the through hole 201. At the same time, before connecting the device to the pipeline, the sealing ring 306 is first fitted into the sealing groove 305 at both ends of the valve body 1. Then, using the positioning pin 301, the outer wall of one side of the port 3 is fitted with the outer wall of one end of the valve body 1. The sealing ring 306 is clamped between the port 3 and the valve body 1 by using the outer wall of the port 3 and the valve body 1. Then, the mounting bolt 304 is rotated and placed into the mounting groove 302. The mounting bolt 304 is rotated and inserted into the threaded hole 303 by rotating the outer wall thread of the mounting bolt 304. The outer wall of the mounting bolt 304 is fitted with the inner wall of the mounting groove 302, so that the port 3 is fixed to the outer wall of the valve body 1 by contact.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
