Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a ball valve which is easy to install. Background Art

[0002] A ball valve is a fluid valve with a spherical internal valve core. A through hole is set in the middle of the spherical valve core. When the through hole rotates to face the internal channel of the valve body, the valve opens. When the through hole rotates to fit closely to the inner wall of the valve body, the valve closes. Since the various surfaces of the spherical valve core are uniform, it will not rotate by itself due to fluid pressure. Therefore, ball valves are usually used in some channels with higher safety requirements.

[0003] In actual use, a handle is usually provided on the top of the valve to drive the valve stem to rotate, thereby controlling the rotation of the valve core. These handles are usually fixed directly on the top of the valve stem. For some special scenarios, in order to avoid accidental touch, the valve handle is set to a split type. In daily use, there is no handle on the top of the valve stem, which can avoid accidental touch. However, when operation is required, it is troublesome to disassemble and assemble the valve handle, and tools are required to tighten the bolts, which is not convenient. For this reason, a ball valve that is easy to install is provided to solve the above problem. Utility Model Content

[0029] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0030] The utility model embodiment discloses a ball valve which is easy to install.

[0031] According to the attached Figure 1-5 As shown, it comprises a ball valve body 1 and a valve cover 2 installed on the top of the ball valve body 1, a spherical valve core 4 is arranged inside the ball valve body 1, a valve stem 7 is arranged on the top of the ball valve body 1, the valve stem 7 is connected to the spherical valve core 4, and the top end of the valve stem 7 is conical;

[0032] A clamping groove 11 is provided on the top of the ball valve body 1, and a fixing member 9 is provided on the outer side of the valve cover 2. The fixing member 9 is fixedly installed inside the clamping groove 11;

[0033] A quick-install valve handle 3 is provided on the top of the valve stem 7, and the quick-install valve handle 3 includes;

[0034] An annular handle 31 and a holder 32 disposed in the middle of the annular handle 31, wherein the holder 32 is movably sleeved on the outer surface of the top end of the valve stem 7;

[0035] The fixed latch 34 is disposed in the inner wall of the annular handle 31 , and the end of the fixed latch 34 is movably plugged into the valve stem 7 .

[0036] The quick-install valve handle 3 also includes;

[0037] Movable grooves 33 are provided at both ends of the annular handle 31;

[0038] The sliding bar 35 is slidably disposed inside the movable groove 33 , and the sliding bar 35 is fixedly connected to the end of the fixed latch 34 .

[0039] A retaining ring 37 is fixedly sleeved on the outer surface of the fixed latch 34 , and a spring 36 is movably sleeved on one end of the fixed latch 34 close to the sliding bar 35 . The spring 36 and the retaining ring 37 are both placed in the inner side wall of the annular handle 31 .

[0040] A sealing member 5 is provided at the inner top of the ball valve body 1 , and the top of the sealing member 5 abuts against the valve cover 2 .

[0041] A rotating handle 10 is fixedly welded to the outer surface of the top end of the valve cover 2, a fixing seat 8 is fixedly welded to the inner bottom of the slot 11, and a fixing member 9 is fixedly installed with the fixing seat 8 by bolts.

[0042] A clamping hole 6 is formed at the top of the valve stem 7 , and the front end of the fixed latch 34 is movably inserted into the clamping hole 6 .

[0043] Working principle: When the device is in use, the base 32 in the middle of the annular handle 31 is pressed downwardly against the top of the valve stem 7. At this time, the conical part at the top of the valve stem 7 is inserted into the middle of the opposite end of the two sets of fixed pins 34, and as the base 32 is pressed downward, the valve stem 7 pushes the two sets of fixed pins 34 to both sides, so that the spring 36 is compressed. When the valve stem 7 completely enters the inside of the base 32, the fixed pin 34 and the clamping hole 6 are in the same horizontal plane. At this time, the annular handle 31 is rotated. When the fixed pin 34 is rotated to face the clamping hole 6, the spring 36 pushes the fixed pin 34 to the inside of the clamping hole 6. At this time, the annular handle 31 is continued to be rotated to drive the valve stem 7 to rotate. After completion, pull the sliding bars 35 on both sides outward to drive the fixing pin 34 to move out from the inside of the card hole 6. At this time, directly lift the annular handle 31 upward and remove it, so as to realize the quick disassembly and assembly of the annular handle 31. During use, the valve cover 2 is inserted into the card slot 11 by inserting the fixing part 9, and then rotating the valve cover 2 by rotating the handle 10, so that the fixing part 9 enters the card slot 11. At this time, the fixing part 9 is opposite to the fixing seat 8. At this time, bolts are installed between the fixing part 9 and the fixing seat 8 to fix them, so as to vertically lock the valve cover 2 through the card slot 11 to avoid the bolt parts sliding up and down during use, resulting in a gap between the valve cover 2 and the ball valve body 1.

[0044] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0045] 1. The base 32 in the middle of the annular handle 31 is movably connected with the clamping hole 6 at the top of the valve stem 7 through two sets of fixed pins 34. By setting the top of the valve stem 7 to a cone, it is convenient for quick plug-in assembly. After use, the sliding bars 35 on both sides are pulled outward to drive the fixed pins 34 to move out of the clamping hole 6. At this time, the annular handle 31 is directly lifted up and removed, thereby realizing quick disassembly and assembly of the annular handle 31.

[0046] 2. The valve cover 2 is fixed by inserting the fixing member 9 into the slot 11 and then installing bolts between the fixing member 9 and the fixing seat 8, so that the valve cover 2 is vertically locked through the slot 11 to prevent the bolt from sliding up and down during use, resulting in a gap between the valve cover 2 and the ball valve body 1.
