The utility model is a filter valve for HVAC equipment, which reduces the possibility of thread slippage on the filter valve screw, increases the service life of the filter valve screw, and can conveniently open the valve body, thereby timely cleaning the dirt filtered by the filter net.

[0004] Most of the existing filter valves are similar to the structure in the patent document. A filter screen is set at the water inlet end of the valve body. Due to the filter screen's blocking effect on impurities, most impurities remain on the water inlet side of the filter screen. Impurities accumulate over a long period of time, affecting the water filtering effect, and further affecting the heating effect. In addition, the long-term accumulation of impurities causes the impurities to not completely accumulate on the side wall of the filter screen, but also extend into the pipe. Simply removing the filter screen part cannot achieve a good cleaning effect. Therefore, in order to solve the above problems, the present application provides a HVAC pipe valve body that is easy to clean. Utility Model Content

DETAILED DESCRIPTION

[0023] The following is combined with Figure 1 - Figure 6 This application is described in further detail.

[0024] Embodiment 1:

[0025] A HVAC pipe valve body that is easy to clean, refer to Figure 1 - Figure 6 , including a valve body consisting of a valve tube 2, a flange 21, a knob 3 and a valve core 31. A filter tube 4 is arranged at the water inlet end of the valve tube 2. A filter screen 9 is arranged inside the filter tube 4. The filter screen 9 is arranged to be inclined forward. A mounting ring is welded on the inner wall of the filter tube 4. The filter screen 9 is fixedly connected to the mounting ring with bolts, so that the filter screen 9 is easy to disassemble, replace and clean.

[0026] Below the filter tube 4, at the bottom front side of the filter screen 9, there is a receiving section 6 that penetrates the filter tube 4. The receiving section 6 is provided with a detachable blocking structure. The receiving section 6 is located outside the filter tube 4, and the outer side of the opening of the receiving section 6 is fixedly connected with an end cap 7 by a thread. The receiving section 6 has a two-section structure, including a connecting section that is connected to the inside of the filter tube 4 and an expansion section at the bottom. The volume of the expansion section is larger than that of the connecting section. In the early stage of impurity deposition, under the action of gravity, the impurities enter the expansion section through the channel of the connecting section for storage, which can effectively reduce the impact on the pipeline's own transportation capacity. When cleaning, the end cap 7 can be unscrewed to clean the impurities inside.

[0027] An openable processing mechanism 8 is also provided above the filter tube 4; the processing mechanism 8 includes a processing tube 81 connected to the inside of the filter tube 4, the processing tube 81 is welded to the outer wall of the filter tube 4, and the end of the processing tube 81 is threadedly connected to the end cover 82. The significance of the processing mechanism 8 is that when there are some impurities in the interior of the receiving section 6 that are difficult to clean or clogged therein, the end cover 82 can be opened, and the position can be cleared through tweezers, probes and other objects, so as to obtain a better cleaning effect and improve the convenience of simple cleaning.

[0028] Both ends of the filter tube 4 are slidably provided with connecting rings 5, and the end connecting ring 5 is threadedly connected to the valve tube 2, and the front connecting ring 5 is used for threaded connection with the external pipeline, and cooperates with the flange 21 of the valve tube 2 to realize the installation of the valve on the pipeline.

[0029] Both ends of the filter tube 4 are provided with an outwardly convex annular sheet, and both connecting rings 5 ​​are provided with an inwardly convex annular sheet. A rubber ring 10 is provided between the outwardly convex annular sheet and the inwardly convex annular sheet at both ends of the filter tube 4. The outwardly convex annular sheet and the inner wall of the connecting ring 5 are gap-matched, and the inwardly convex annular sheet and the outer wall of the filter tube 4 are gap-matched. There is an overlapping part between the two in side view. The rubber ring 10 is provided between the overlapping parts to ensure the sealing between the filter tube 4 and the connecting ring 5.

[0030] Rubber rings 11 are provided on the outer sides of both ends of the filter tube 4, and the rubber rings are provided on the inner side of the connecting ring 5. The filter tube 4 is in the state of the connecting ring 5 at one end being connected to the valve tube 2 when it leaves the factory. Therefore, when installing the filter tube 4, first push the connecting ring 5 to one side of the filter tube 4 so that its end does not exceed the position of the outer convex annular piece, and then insert the rubber ring 11 between the filter tube 4 and the external pipeline, and then screw the connecting ring 5 and the external pipeline to lock them, so as to ensure the sealing of the valve body after installation.

[0031] When performing a larger degree of cleaning, close the external main valve and the valve core 31 at the valve tube 2, rotate both connecting rings 5 ​​toward the centerline position of the filter tube 4, and after disconnecting from the external pipeline and the valve tube 2, the filter tube 4 can be removed, and the filter section can be completely removed for cleaning. At the same time, since the end of the external pipeline is free, impurities that may be present at the end can also be cleaned. This increases the convenience of cleaning while expanding the cleaning range and improving the cleaning effect.

[0032] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
