Abstract
Description
Technical Field
[0001] This utility model relates to the field of kitchen and bathroom technology, specifically to an integrated filter-type water flow pipe. Background Technology
[0002] Existing valve bodies use a valve core to control the flow of water, typically employing a combination of moving and stationary ceramic discs, achieved through the alignment and misalignment of holes on these discs. With increasingly fierce market competition, there is an urgent need to develop a low-cost angle valve structure. The inventors discovered that the valve body's function can be achieved by using an abutment section in conjunction with an existing stop valve on the market.
[0003] Water in the tap water network inevitably contains some scale and sediment. If this scale and sediment enters the water-using equipment, it will shorten the life and performance of the equipment. Therefore, it is necessary to treat the scale and sediment in the water.
[0004] In view of this, the inventor conducted in-depth research on the aforementioned deficiencies in the prior art, which led to the creation of this case. Utility Model Content
[0005] The main purpose of this utility model is to provide a filter-type water-passing pipe, which is installed in the angle valve housing and cooperates with the stop valve, and can significantly reduce the cost of the angle valve.
[0006] To achieve the above objectives, the solution of this utility model is:
[0007] An integrated filter-type water-passing pipe includes an integrally connected abutment section, a filter screen frame, a threaded section, and a handle connection part; the outer wall of the threaded section is formed with threads for connecting to a valve body housing; a water-passing channel is formed inside the abutment section, and the water-passing channel communicates with the inner cavity of the filter screen frame.
[0008] Furthermore, the contact section, filter frame, threaded section, and handle connection part are integrally injection molded from plastic material.
[0009] Furthermore, a counterweight is installed inside the handle connection part, and a knob for driving the handle connection part is also installed outside the handle connection part.
[0010] Furthermore, a first sealing ring groove is provided at the connection between the threaded section and the filter screen frame.
[0011] Furthermore, the abutment section is an abutment pipe integrally connected to the filter screen frame.
[0012] Furthermore, a second sealing ring groove is provided on the outer wall of the abutment pipe.
[0013] Furthermore, the abutting section is an abutting ring integrally connected to the filter frame.
[0014] Furthermore, a cylindrical filter screen is integrally formed on the filter screen frame.
[0015] Furthermore, a cylindrical filter screen is installed on the filter frame.
[0016] Furthermore, the thread on the outer wall of the threaded segment is an external thread.
[0017] With the above structure, the filter-type water-passing pipe of this utility model has at least the following beneficial effects:
[0018] 1. By integrating the abutment section, filter frame, threaded section, and handle connection into a single unit, the abutment section can move axially when the handle connection is rotated due to the threaded connection to the valve body shell. Specifically, when rotated in the closing direction, the abutment section moves outwards, closing the stop valve. This integrated structure allows for production via injection molding or other methods, resulting in a simple structure, easy assembly, and reduced production costs for angle valves.
[0019] 2. The filter screen frame can have filter holes integrated into it, or the filter screen can be a separate unit installed on the filter screen frame. The separate filter screen can be a commercially available metal filter screen, which is very convenient to purchase.
[0020] 3. The length of the abutment section can be a shorter abutment ring or a longer abutment pipe, depending on the internal structure of the valve body shell. A second sealing ring is provided on the outer wall of the abutment pipe to prevent mud and sand from entering the gap between the abutment pipe and the valve body shell and affecting the axial movement of the abutment pipe. Attached Figure Description
[0021] Figure 1 This utility model relates to a cross-sectional structural schematic diagram of an integrated filter-type water-passing pipe.
[0022] Figure 2 This is a cross-sectional view of the utility model in use.
[0023] In the picture:
[0024] Abutting section 1; water passage 11; second sealing ring groove 12; filter screen frame 2; threaded section 3; first sealing ring groove 31; handle connection part 4; counterweight part 41; knob 42; valve body shell 100; stop valve 200. Detailed Implementation
[0025] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.
[0026] like Figure 1 and Figure 2As shown, this utility model relates to an integrated filter-type water-passing pipe, which includes an integrally connected abutment section 1, a filter screen frame 2, a threaded section 3, and a handle connection part 4; the outer wall of the threaded section 3 is formed with threads for connecting to the valve body housing 100; a water-passing channel 11 is formed in the abutment section 1, and the water-passing channel 11 communicates with the inner cavity of the filter screen frame 2.
[0027] Thus, this utility model relates to a filter-type water-passing connecting pipe, which integrates the abutment section 1, filter screen frame 2, threaded section 3, and handle connection part 4 into one unit. Since the threaded section 3 is threadedly connected to the valve body shell 100, the abutment section 1 can move axially when rotated via the handle connection part 4. Specifically, when rotated in the closing direction, the abutment section 1 can move outward accordingly, causing the stop valve 200 to close. This integrated structure allows for production via injection molding, resulting in a simple structure, convenient assembly, and reduced production costs for angle valves. Furthermore, the abutment section 1, filter screen frame 2, threaded section 3, and handle connection part 4 are integrally injection molded from plastic material.
[0028] The filter frame 2 can have filter holes integrally formed, meaning that a cylindrical filter screen is integrally molded on the filter frame 2. Alternatively, a separate filter screen can be installed on the filter frame 2. The separate filter screen can be a commercially available metal filter screen, which is very convenient to purchase.
[0029] Preferably, a counterweight 41 is installed inside the handle connection part 4, and a knob 42 for driving the handle connection part 4 is also installed outside the handle connection part 4. The counterweight 41 improves the overall feel.
[0030] Preferably, a first sealing ring groove 31 is provided at the connection between the threaded section 3 and the filter screen frame 2. The first sealing ring groove 31 is used to install the first sealing ring, thereby preventing water in the valve body from leaking through the gaps in the threaded section 3.
[0031] Preferably, the abutment section 1 is an abutment pipe integrally connected to the filter screen frame 2. The length of the abutment pipe is determined according to the internal structure of the valve body shell.
[0032] Preferably, the outer wall of the abutment pipe is provided with a second sealing ring groove 12. The second sealing ring on the outer wall of the abutment pipe prevents mud and sand from entering the gap between the abutment pipe and the valve body shell and affecting the axial movement of the abutment pipe.
[0033] Preferably, the abutment section 1 is an abutment ring integrally connected to the filter screen frame 2. The abutment section 1 can be a relatively short abutment ring, which is set according to the internal structure of the valve body shell.
[0034] Preferably, the thread on the outer wall of the threaded section 3 is an external thread. This allows the threaded section 3 to be installed on the inner side of the angle valve housing. Alternatively, the threaded section 3 can be an internal thread, connecting with the thread on the outer wall of the angle valve housing. Rotation of the threaded section 3 allows adjustment of the axial position of the water-passing pipe relative to the angle valve housing 100. Figure 2 As shown, the water-passing connecting pipe can abut against the inner core of the water-stop valve to control whether the water-stop valve is in a water-flow state or a water-stop state.
[0035] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
