Description

Technical Field

[0001] The utility model belongs to the technical field of valves, and particularly relates to a safe natural gas inlet valve. Background Art

[0002] In order to prevent the valve stem handle from falling off, existing natural gas inlet valves all use fixed handles. Although the fixed handle can prevent falling off, there is a hidden danger of accidental contact during use, which can easily cause accidental opening and closing, leading to accidents, and the safety performance is relatively low.

[0003] Currently, there are also handles with locking valves. Although they can self-lock, they have a complex structure and take up a large space, which has a certain impact on disassembly and assembly. In addition, when opening, closing, and adjusting the flow, they need to be unlocked first and then self-locked, which is troublesome to operate.

[0004] At the same time, when the inlet valve is connected to the inlet meter, two wrenches are required, one is put on the hexagonal outside of the valve body, and the other is put on the hexagonal outside of the inlet meter joint to loosen or tighten the threaded joint for disassembly and assembly; when connecting the pipeline, two wrenches are also required, one is put on the hexagonal outside of the valve body, and the other is put on the hexagonal outside of the pipe joint to loosen or tighten the threaded joint for disassembly and assembly.

[0005] The outer hexagon of the valve body and the outer hexagon of the pipe joint and the outer hexagon of the inlet table are closely adjacent, and the two wrenches often interfere with each other during the disassembly and assembly process. Since the inlet valve is close to the wall, it is inconvenient to disassemble and assemble it by leaving the wall and pipeline aside. Utility Model Content

[0006] In order to overcome the deficiencies of the prior art, the utility model provides a safe inlet valve which is easy to disassemble and assemble and has a simple structure, is convenient to disassemble and assemble, and has a strong safety performance.

[0007] The technical solution of the utility model is: a safe household valve that is easy to disassemble and assemble, including: a quick-change handle, a valve stem, a valve body, and a handle seat. The handle seat is fixedly connected to the center of the bottom of the valve body. A lower screw hole B is designed on the handle seat. The quick-change handle can be connected to the handle seat through the lower screw hole B. The lower end of the valve stem passes through the center hole at the top of the valve body and is connected to the valve core in the valve body cavity. An upper screw hole A is designed on the upper part of the valve stem. The quick-change handle can be connected to the valve stem through the upper screw hole A.

[0008] The lower screw hole B is designed as a through hole, which allows the quick-change handle to be installed on either side.

[0009] The lower screw hole B is designed in the horizontal direction of the center of the handle seat.

[0010] The thread of the quick-change handle matches the upper screw hole A and the lower screw hole B.

[0011] When the utility model is disassembled and assembled, the quick-change handle is connected to the handle seat through the lower screw hole B to serve as an installation handle. Only one wrench is needed to complete the disassembly and assembly of the house valve, thereby avoiding the mutual interference of the two wrenches during work and reducing the number of installation tools.

[0012] After the valve is disassembled and assembled, the valve is in working state. Remove the handle seat from the lower screw hole B and install it into the upper middle screw hole A on the upper part of the valve stem. Turn the quick-change handle to drive the valve stem, and drive the valve core in the valve body cavity to rotate through the lower end of the valve stem to operate the valve switch opening and closing and flow regulation, acting as a valve switch handle.

[0013] After the valve is opened and closed, promptly remove the quick-change handle from the screw hole on the valve stem and reinstall it into the screw hole B under the handle seat to prevent the valve stem from being accidentally touched and causing accidental opening or closing, greatly reducing safety hazards; at the same time, the screw hole B under the handle seat is threaded to prevent the handle from falling off.

[0014] Since the installation position of the inlet valve of the utility model is close to the wall and adjacent to the inlet meter, the lower screw hole B is designed as a through hole, so that the quick-change handle can be installed on both sides arbitrarily, which is convenient for leaving the wall and the air pipe; if the air pipe is run along the left side of the wall, the quick-change handle can be installed on the right side; if the air pipe is run along the right side of the wall, the quick-change handle can be installed on the left side, thereby avoiding interference between the quick-change handle and the air pipe and the wall.

[0015] In summary, the utility model can serve as an installation handle and a switch handle, can be switched back and forth, and is flexible and versatile, which not only ensures the safety of the valve, but also avoids the situation where the two wrenches interfere with each other during work, and improves the efficiency of disassembly and assembly. It occupies a small space, is convenient for leaving the door, wall and pipeline, is more suitable for wall installation, and can replace the lockable valve handle to ensure the safety of the valve, and has strong practicality.

[0018] like Figure 1 ,like Figure 2 As shown, a safe household valve that is easy to disassemble and assemble includes: a quick-change handle 1, a valve stem 2, a valve body 3, a handle seat 4, and a valve core 5. The handle seat 4 is fixedly connected to the center of the bottom of the valve body 3. The handle seat 4 is designed with a lower screw hole B. The quick-change handle 1 can be connected to the handle seat 4 through the lower screw hole B. The lower end of the valve stem 2 passes through the center hole at the top of the valve body 3 and is connected to the valve core 5 in the cavity of the valve body 3. An upper screw hole A is designed on the upper part of the valve stem 2. The quick-change handle 1 can be connected to the valve stem 2 through the upper screw hole A.

[0019] The lower screw hole B is designed as a through hole, which allows the quick-change handle to be installed on both sides arbitrarily, so as to make way for the wall and the air pipe.

[0020] The lower screw hole B is designed in the horizontal direction of the center of the handle seat 4.

[0021] The thread of the quick-change handle 1 matches the upper screw hole A and the lower screw hole B, which is convenient for flexible switching.
