DETAILED DESCRIPTION

[0026] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Example 1

[0028] The preferred embodiment of the linear valve body provided by the utility model is as follows Figures 1 to 6 As shown: a linear valve body comprises a valve body 1 , a filter mechanism 2 is arranged inside the valve body 1 , and the filter mechanism 2 comprises an assembly component 21 and a fastening component 22 .

[0029] In this embodiment, the assembly component 21 includes a baffle 211 , an assembly ring 212 and a filter 213 . By setting the assembly component 21 , the assembly ring 212 can be limited under the action of the baffle 211 to avoid sliding inside the valve body 1 .

[0030] In this embodiment, the baffle 211 is fixedly connected to the inside of the valve body 1 , a mounting ring 212 is attached to one side of the baffle 211 , and a filter screen 213 is fixedly connected to the inner wall of the mounting ring 212 .

[0031] In this embodiment, the fastening assembly 22 includes a mounting groove 221, a first spring 222 and a fixing plate 223. By providing the fastening assembly 22, the assembly ring 212 can be quickly fixed and the assembly ring 212 can be quickly disassembled.

[0032] In this embodiment, the mounting groove 221 is arranged on the left side of the valve body 1, and a first spring 222 is fixedly connected inside the mounting groove 221. The tail of the first spring 222 is fixedly connected to a fixing plate 223 which is slidably connected to the mounting groove 221 and located on one side of the assembly ring 212.

[0033] In this embodiment, the assembly ring 212 and the fixing plate 223 are in a tightly fitted state, and the fixing plate 223 is completely hidden in the interior of the installation groove 221. The assembly ring 212 forms a fixed structure inside the valve body 1 through the fixing plate 223. When the fixing plate 223 is pulled sideways, the fixing plate 223 will slide along the installation groove 221 and gradually break away from the assembly ring 212. At this time, the assembly ring 212 loses the fixing force of the fixing plate 223 and can be removed from the side of the baffle 211, thereby achieving the purpose of disassembling the filter 213.

[0034] Example 2

[0035] Based on Example 1, a preferred embodiment of the linear valve body provided by the present invention is as follows: Figures 1 to 6 As shown: the top of the valve body 1 is rotatably connected to a handwheel 3, the side of the handwheel 3 is fixedly connected to a connecting plate 4, the inside of the connecting plate 4 is slidably connected to a slider 5, the top of the slider 5 is fixedly connected to a second spring 6 fixedly connected to the connecting plate 4, the side of the slider 5 is fixedly connected to an insertion rod 7, the surface of the insertion rod 7 is slidably connected to a first fixing rod 8 fixedly connected to the top of the valve body 1, and the side of the first fixing rod 8 is fixedly connected to a second fixing rod 9 located at the top of the valve body 1.

[0036] In this embodiment, the second fixing rod 9 is located on the rotation trajectory of the insertion rod 7. The handwheel 3 forms a fixed structure through the insertion rod 7. The insertion rod 7 is pulled upward to control the slider 5 to slide upward along the connecting plate 4, and then the handwheel 3 can be controlled to rotate. When the handwheel 3 controls the insertion rod 7 to rotate to the second fixing rod 9, the insertion rod 7 is released. Under the action of the second spring 6, the insertion rod 7 will be embedded in the interior of the second fixing rod 9, thereby fixing the handwheel 3 again.

[0037] The working principle and use process of the utility model are as follows: first, when the valve body 1 is used, by setting the filter screen 213, the filter screen 213 can filter the liquid passing through the inside of the valve body 1 to prevent impurities in the water from clogging the inside of the valve body 1. After the filter screen 213 is used for a long time, more and more impurities will accumulate on its side, causing the filter screen 213 to be blocked. After the left side of the valve body 1 and the conduit are disassembled, the filter screen 213 is exposed, and the fixing plate 223 can be pulled to the side, and the fixing plate 223 will slide along the installation groove 221 and gradually break away from the assembly ring 212. At this time, the assembly ring 212 loses the fixing force of the fixing plate 223 and can be removed from the side of the baffle 211, thereby achieving the purpose of disassembling the filter screen 213.

[0038] Next, in order to avoid accidental touching of the handwheel 3 during use, an insertion rod 7 is provided. Under the action of the second spring 6, the insertion rod 7 will be inserted into the interior of the first fixing rod 8, so as to limit the handwheel 3 and avoid accidental touching of the handwheel 3. When the handwheel 3 needs to be rotated, the insertion rod 7 can be pulled upward to control the sliding block 5 to slide upward along the connecting plate 4, and then the handwheel 3 can be controlled to rotate. When the handwheel 3 controls the insertion rod 7 to rotate to the second fixing rod 9, the insertion rod 7 is released. Under the action of the second spring 6, the insertion rod 7 will be embedded into the interior of the second fixing rod 9, and the handwheel 3 can be fixed again.

[0039] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
