[0002] Internally threaded (or socket welded) ball valves, as the simplest type of ball valve, are widely used due to their low manufacturing and installation costs and high application value. Among them, the straight-pipe structure valve body has superior sealing reliability compared to existing two- or three-body types, and its lower manufacturing cost makes it the most popular among users. A search revealed existing public technology publication number CN205978554U, a straight-pipe internally threaded ball valve, relating to the valve field. This straight-pipe internally threaded ball valve includes a valve body, a ball disposed within the valve body, and a valve cover threadedly connected to one end of the valve body. A threaded connection interface and a valve seat support are provided at the other end of the valve body. The valve cover also has a threaded connection interface, and a valve seat mounting groove is provided at the top of the valve cover. This invention effectively improves the reliability of the valve.

[0003] In summary: Although the above case solved the corrosion problem of the threaded pipe, the handle of the internal thread ball valve in the above solution is external, and unauthorized personnel can also adjust the handle of the straight-through internal thread self-locking ball valve. If unauthorized personnel adjust the handle during the operation of the ball valve, it will cause the ball valve to stop working. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of the existing technology by providing an internally threaded ball valve with a handle limiting structure. This solves the problem mentioned in the background art, where the handle switch is located outside the valve, and unauthorized personnel can adjust the handle of the straight-through internally threaded self-locking ball valve. If unauthorized personnel adjust the handle during the operation of the ball valve, it will cause the ball valve to stop working.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an internal thread ball valve with a handle limiting structure, comprising a handle limiting structure, wherein a protective structure is installed on one side above the handle limiting structure;

[0006] The handle limiting structure includes an internally threaded ball valve body as the main body, and a through hole recess is fixedly installed on one side of the internally threaded ball valve body. At the same time, an operating handle with a connection hole is provided on the upper part of the internally threaded ball valve body.

[0007] The through-hole recess is rotatably equipped with a rotating connecting seat with the same connecting hole.

[0008] By adopting the above technical solution, the through-hole recess can achieve both fixed installation and internal rotational connection.

[0009] Preferably, the rotating connecting seat is provided with a rod having the same connecting hole through the connecting hole, and one end of the rod is provided with a limiting lock that is connected through the connecting hole.

[0010] By adopting the above technical solution, the limit lock can achieve through-locking.

[0011] Preferably, the protective structure includes a retainer fixed to the other side of the internal thread ball valve body, and the retainer engages with the matching rod. At the same time, a protective cover covering the upper part of the through hole recess is fixedly installed on the upper part of the matching rod.

[0012] By adopting the above technical solution, the matching rod is set to achieve the matching insertion.

[0013] Preferably, the rotating connecting seat has an overall U-shaped configuration.

[0014] By adopting the above technical solution, the rotation adjustment is achieved through the set rotating connecting seat.

[0015] Preferably, the insertion rod is T-shaped.

[0016] By adopting the above technical solution, the insertion limit is achieved by setting the insertion rod.

[0017] Preferably, the protective cover is made of plastic material.

[0018] By adopting the above technical solution, the protective cover can achieve the purpose of wrapping and protecting.

[0019] Compared with the prior art, the beneficial effects of this utility model are: the internal thread ball valve with handle limiting structure,

[0020] (1) This case solves the problem that if the handle switch is outside, unauthorized personnel can also adjust the handle of the straight-through internal thread self-locking ball valve. If unauthorized personnel adjust the handle during the operation of the ball valve, the ball valve will stop working. After the operating handle is turned, the connecting seat is manually rotated to wrap the operating handle. The rod is then inserted into the connecting hole and locked through by the limit lock. The limit lock locks the rod through and locks it, thus preventing unauthorized personnel from moving it at will.

[0021] (2) By setting up a protective structure, the limit lock and operating handle are easily corroded and rusted when exposed to the outside for a long time, which makes them unable to rotate and open. After the operating handle or limit lock is locked through, hold the protective cover to make the matching rod and the card seat engage and limit the position. Then use the protective cover to wrap and protect the limit lock or operating handle, thereby avoiding rainwater corrosion or rust. Attached Figure Description

[0028] 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.

[0029] Please see Figure 1-5 This utility model provides a technical solution: an internally threaded ball valve with a handle and limiting structure, such as... Figure 1 and Figure 2As shown, it includes a handle limiting structure 1, which includes an internally threaded ball valve body 101 as the main body. A through-hole recess 102 is fixedly installed on one side of the internally threaded ball valve body 101. At the same time, an operating handle 103 with a connection hole 104 is provided on the upper part of the internally threaded ball valve body 101. A rotating connecting seat 105 with the same connection hole 104 is rotatably provided inside the through-hole recess 102. The rotating connecting seat 105 is U-shaped. When the above components are U-shaped, it not only reflects the through-hole of the above components, but also reflects the rotatable connection of the above components inside the through-hole recess 102. Furthermore, when the above components are U-shaped, it effectively reflects the rotational wrapping and rotational force separation of the above components on the operating handle 103.

[0030] like Figure 3 and Figure 4 As shown, in the above scheme, the rotating connecting seat 105 is further provided with a rod 107 with the same connecting hole 104 through the connecting hole 104, and one end of the rod 107 is provided with a limiting lock 106 that is connected through the connecting hole 104. The overall shape of the rod 107 is "T". When the overall shape of the above components is "T", it not only reflects the through-limiting function of the above components, but also reflects the through-locking function of the above components. Furthermore, when the overall shape of the above components is "T", it effectively reflects the simplicity of the overall design of the above components and the quick pull-out operation.

[0031] like Figure 5 As shown, a protective structure 2 is installed on one side above the handle limiting structure 1. The protective structure 2 includes a retainer 201 fixed on the other side above the internally threaded ball valve body 101, and the retainer 201 engages with the matching rod 202. At the same time, a protective cover 203 is fixedly installed above the matching rod 202, covering the through hole recess 102. The protective cover 203 is made of plastic material. By using plastic material for the entire component, not only is the overall weight of the component light, but rainwater corrosion and rust are also avoided. This not only effectively extends the service life of the component but also avoids increasing the overall manufacturing cost of the component.

[0032] In the above scheme, after the operating handle 103 is rotated, the rotating connecting seat 105 wraps around the operating handle 103. Then, the insert rod 107 is used to connect the through hole recess 102, the rotating connecting seat 105 and the operating handle 103 through and through. After the limit lock 106 is used to lock through, the matching rod 202 is held and engaged with the card seat 201, so that the protective cover 203 can wrap and protect the operating handle 103, the through hole recess 102, the rotating connecting seat 105 and the limit lock 106.
