Description

Technical Field

[0001] This utility model relates to the field of heating valve technology, and more specifically, to a manual ball valve with a detachable handwheel. Background Technology

[0002] Ball valves, which originated in the 1950s, have developed into a major type of valve over the past half-century. They are primarily used to cut off or connect media, and can also be used for fluid regulation and control. V-type ball valves offer more precise flow regulation and control, while three-way ball valves are used for distributing media and changing their flow direction.

[0003] Manual ball valves are a relatively new type of ball valve. They have some unique advantages due to their structure, such as frictionless switching, wear-resistant seals, low opening and closing torque, and the ability to regulate and strictly shut off the medium. They are widely used in applications requiring strict shut-off, such as individual household heating management.

[0004] Individual household heating management involves installing separate valves to control the flow of heat into each household, achieving "one valve per household." Controlling the opening and closing of these valves allows for precise management of each user's heating behavior. These valves can be manual or electric. Electric valves are easier to control, but require an electric actuator for each valve and related equipment to communicate with the management system, resulting in a larger investment in the entire heating control system. For economic reasons, heating companies typically choose manual valves as the mandatory control valves for each household.

[0005] Manual ball valves can be categorized into handwheel-driven and handle-driven types based on their actuation method. Manual ball valves have a simple structure, open and close quickly, requiring only a 90° rotation to go from fully open to fully closed, making them easy to control.

[0006] However, existing manual ball valves have the following drawbacks:

[0007] 1. Some manual ball valves have poor structural design stability and are prone to sliding, which affects operating efficiency. Especially when at the bottom or higher part of the pipeline, they cannot maintain uniform force, making operation even more inconvenient.

[0008] 2. An unreasonable sealing structure design reduces the sealing effect and makes leakage more likely. Utility Model Content

[0009] In view of this, the purpose of this utility model is to address the problems that easily occur in existing manual ball valves by designing a manual ball valve with a detachable handwheel. By designing the upper cavity structure of the valve body, a handwheel assembly can be installed, and a dedicated electronic lock head can also be placed. It can not only be used as a regular ball valve, with a stable structure, easy operation, and good sealing performance, but also achieve valve unlocking and unlocking through the electronic lock head, realizing dual-purpose valve. This saves on equipment procurement costs, installation costs, and time, and is convenient and quick to install and operate, with wide applicability.

[0010] This utility model provides a manual ball valve with a detachable handwheel, comprising: a valve body, wherein the valve body is provided with a handwheel assembly, a valve stem, and a valve ball that are coaxially and detachably connected from top to bottom; the lower part of the valve body includes a first valve body and a second valve body that are threadedly connected, and a PTFE valve seat is provided on each side of the valve ball, with each PTFE valve seat being embedded in the first valve body and the second valve body respectively.

[0011] After the handwheel assembly is installed, a cavity will remain at the bottom of the upper chamber of the valve body. This cavity allows for the smooth installation of a locking head designed to be compatible with this ball valve. When the ball valve is closed, the handwheel assembly can be removed, and the dedicated locking head can be installed into the upper chamber of the valve body. This manual ball valve can then be used as a locking valve.

[0012] Furthermore, the handwheel assembly includes: a handwheel cover, a handwheel fixing member, and a handwheel arranged sequentially from the outside to the inside. The handwheel cover is snapped into the handwheel, the handwheel fixing member is snapped into the valve body, and the handwheel is inserted into the upper cavity of the valve body through the handwheel fixing member.

[0013] Furthermore, the handwheel is provided with a vertical handwheel protrusion and a handwheel groove, and the valve body is provided with a vertical protrusion and a groove, the handwheel protrusion and the handwheel groove respectively cooperating with the protrusion and the groove.

[0014] The handwheel can only be installed normally after the handwheel protrusion and the groove on the valve body, and the handwheel groove and the protrusion on the valve body, are aligned on the same side.

[0015] Furthermore, an annular flange is provided in the upper cavity of the valve body along the circumference of the cavity, and an opening is provided on the flange along the axial direction of the cavity.

[0016] Furthermore, the handwheel assembly also includes: a spring ball seat and a spring ball arranged sequentially from top to bottom between the handwheel fixing member and the handwheel, the spring ball seat and the spring ball being interference-fitted together, and the spring ball seat and the handwheel being interference-fitted together.

[0017] When the manual ball valve is opened, the spring ball in the handwheel assembly rotates with the handwheel and is compressed inward by the flange inside the upper cavity of the valve body. When the valve is fully closed, the spring ball rotates with the handwheel to the opening of the flange inside the upper cavity of the valve body, and the spring ball will pop out. The operator will clearly feel the "click" sound when the spring ball pops out, indicating that the valve is fully closed.

[0018] This structural design allows operators to determine that the valve is fully closed by a "click" sound when it is shut off, saving time for operators to confirm whether the valve is fully closed.

[0019] The upper cavity of the valve body is specifically designed to house the handwheel assembly and is compatible with the replacement of a dedicated electronic lock head for locking. After removing the handwheel assembly (handwheel holder, handwheel, spring ball seat, and spring ball) from the upper cavity of the valve body, a matching dedicated electronic lock head can be installed, enabling the manual ball valve to perform both the opening and closing functions of a regular ball valve and the valve locking function.

[0020] Furthermore, the handwheel cover is provided with a cover buckle, the handwheel fixing component is provided with a handwheel buckle, and the valve body is provided with a slot that cooperates with the handwheel buckle.

[0021] The handwheel cover is connected to the handwheel via a cover clip, and the handwheel fixing component is connected to the valve body via a handwheel clip; the handwheel cover has indications of valve body opening and closing, making it convenient for the operator to identify the valve body status.

[0022] Handwheel clip one on the handwheel fixing component is installed at slot one on the valve body, and handwheel clip two is installed at slot two. The handwheel fixing component can limit the rotation of the handwheel, allowing the ball valve to open and close.

[0023] Furthermore, the handwheel fixing component is provided with a handwheel fixing slot, which cooperates with the handwheel protrusion.

[0024] When the valve is closed, the handwheel can be disassembled and installed. The handwheel protrusion on the handwheel moves along the handwheel fixing slot on the handwheel fixing part, so that the handwheel can be smoothly installed into the upper cavity of the valve body.

[0025] Furthermore, a plug-in buckle is fixedly provided at the upper end of the spring ball seat, and the plug-in buckle is fixedly connected to the handwheel.

[0026] The handwheel is connected to the valve body via a plug-in clip on a spring ball seat assembled with the handwheel. Rotating the handwheel 90° will open the manual ball valve. Once the valve is open, the handwheel cannot be disassembled.

[0027] Furthermore, the upper end of the valve ball is provided with a groove, and the valve stem passes through the upper cavity of the valve body from top to bottom and is inserted into the groove; the lower end of the handwheel is provided with a flat groove, and the upper part of the valve stem is provided with a flat rod, which is inserted into the flat groove. When assembling the ball valve, the flat rod at the upper part of the valve stem will enter the flat groove at the lower end of the handwheel.

[0028] Furthermore, the valve stem is radially fitted with O-rings (preferably two) to prevent liquid from overflowing from the valve.

[0029] Compared with the prior art, the beneficial effects of this utility model are:

[0030] The manual ball valve with a detachable handwheel provided by this utility model has a simple and reasonable structure with strong overall integrity. By designing the upper cavity structure of the valve body, it can not only install the handwheel assembly, but also house a special electronic lock head. It can be used as a regular ball valve, with a stable structure, easy operation, and good sealing performance. Moreover, the valve can be locked and unlocked through the electronic lock head, achieving dual-purpose functionality. This saves on equipment procurement costs, installation costs, and time. It is convenient and quick to install and operate, has good applicability, and has broad prospects for promotion and application. Attached Figure Description

[0048] Example

[0049] This utility model embodiment provides a manual ball valve with a detachable handwheel, such as... Figure 1 The valve body includes a valve body with a handwheel assembly, valve stem 5, and valve ball 3 arranged coaxially and detachably from top to bottom. The lower part of the valve body includes two threaded valve bodies 1 and 2. A PTFE valve seat 4 is located on each side of the valve ball 3, with each PTFE valve seat 4 embedded in either valve body 1 or valve body 2. After the handwheel assembly is installed, a cavity 12 will remain at the bottom of the upper cavity 13 of the valve body (e.g., ...). Figure 1 As shown, cavity 12 ensures smooth installation of the locking head designed for compatibility with this ball valve. When the ball valve is closed, the handwheel assembly is disassembled, and the dedicated locking head is installed into the upper cavity 13 of the valve body, allowing the manual ball valve to be used as a locking valve. The upper end of the ball 3 has a slot, and the valve stem 5 passes through the upper cavity 13 of the valve body from top to bottom and is inserted into the slot. The lower end of the handwheel 6 has a flat groove, and the upper part of the valve stem 5 has a flat rod, which is inserted into the flat groove. During ball valve assembly, the flat rod at the upper part of the valve stem 5 enters the flat groove at the lower end of the handwheel 6. Two O-rings 11 are radially installed on the valve stem 5 to prevent liquid leakage from the valve.

[0050] like Figure 2 , Figure 3 , Figure 4 As shown, the handwheel assembly includes: a handwheel cover 10, a handwheel fixing member 9, and a handwheel 6 arranged sequentially from the outside to the inside.

[0052] The handwheel 6 can only be installed normally after the handwheel protrusion 601 and the groove 102 on the valve body, and the handwheel groove 602 and the protrusion 101 on the valve body, are aligned on the same side.

[0053] like Figure 7 , Figure 8As shown, an annular flange 106 is provided circumferentially within the upper cavity 13 of the valve body, and an opening 105 is provided axially along the flange. The handwheel assembly also includes a spring ball seat 8 and a spring ball 7 arranged sequentially from top to bottom between the handwheel fixing member 9 and the handwheel 6. The spring ball seat 8 and the spring ball 7 are interference-fitted, and the spring ball seat 8 and the handwheel 6 are also interference-fitted. When the manual ball valve is opened, the spring ball 7 in the handwheel assembly rotates with the handwheel 6 and is compressed inward by the flange 106 inside the upper cavity 13 of the valve body. When the valve is fully closed, the spring ball 7 rotates with the handwheel 6 to the opening 105 of the flange 106 inside the upper cavity 13 of the valve body, and the spring ball 7 pops out. The operator can clearly hear a "click" sound when the spring ball 7 pops out, indicating that the valve is fully closed. This structural design allows the operator to determine whether the valve is fully closed by the "click" sound when closing the valve, saving time for confirming whether the valve is fully closed.

[0054] The upper cavity 13 of the valve body is specifically designed to house the handwheel assembly and is compatible with the replacement of a dedicated electronic lock head for locking. After removing the handwheel assembly (handwheel fixing part 9, handwheel 6, spring ball seat 8, and spring ball 7) from the upper cavity 13 of the valve body, a matching dedicated electronic lock head can be installed, enabling the manual ball valve to perform both the opening and closing functions of a regular ball valve and the valve locking function.

The handwheel fixing component 9 can limit the rotation of the handwheel 6, allowing the ball valve to open and close. The handwheel fixing component 9 is provided with a handwheel fixing slot 903, which cooperates with the handwheel protrusion 601. When the valve is closed, the handwheel 6 can be disassembled and assembled. The handwheel protrusion 601 on the handwheel 6 moves along the handwheel fixing slot 903 on the handwheel fixing component 9, allowing the handwheel 6 to be smoothly installed into the upper cavity of the valve body.

[0057] like Figure 10As shown, a plug-in clip 801 is fixedly installed at the upper end of the spring ball seat 8. The plug-in clip 801 is fixedly connected to the handwheel 6, and the handwheel 6 is connected to the valve body through the plug-in clip 801 on the spring ball seat 8. The manual ball valve can be opened by rotating the handwheel 90°.
