Abstract
Description
Technical Field
[0001] This utility model relates to the field of valve technology, specifically to a straight-through check valve that facilitates the cleaning of impurities. Background Technology
[0002] A straight-through check valve is a common type of valve that allows the medium to flow in only one direction, preventing backflow. However, in actual use, the fluid often carries impurities, which can easily accumulate inside the check chamber, affecting the normal operation and service life of the valve.
[0003] Currently, when cleaning impurities inside the check chamber, a high-pressure water gun is required for high-pressure rinsing. However, some impurities may still remain in the corners of the check chamber. In this case, tools can only be used to remove them, which makes the process of cleaning impurities too cumbersome and requires a lot of time and manpower, causing some inconvenience to the staff. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a straight-through check valve that facilitates the cleaning of impurities. The straight-through check valve uses a detachable impurity collection box to fill the check chamber. At this time, all impurities will be concentrated in the impurity collection box. After the front straight-through valve body is disassembled, the check chamber can be opened. At this time, the impurity can be cleaned by directly disassembling the impurity collection box. Its operation is simple and more convenient when cleaning impurities.
[0005] The technical solution of this utility model is implemented as follows:
[0006] A straight-through check valve for easy cleaning of impurities includes a straight-through check valve body, which has a check chamber and an inlet and an outlet that are connected to the front and rear of the check chamber.
[0007] The check chamber is equipped with a check valve core and an elastic component. The check valve core, pushed by the elastic component, completely blocks the water inlet, thereby achieving unidirectional flow from the water inlet to the water outlet.
[0008] The straight-through check valve body includes a front straight-through valve body and a rear straight-through valve body that is detachably installed on the front straight-through valve body. The check chamber can be opened after the front straight-through valve body is detached.
[0009] The check chamber is fitted with a removable collection box, which is connected to the inlet and outlet water interfaces and is completely fitted to the inner wall of the check chamber. The check valve core and the elastic component are located inside the collection box.
[0010] Using the above solution, the straight-through check valve uses a detachable collection box to fill the check chamber. At this time, all impurities will be concentrated in the collection box. After the front straight-through valve body is disassembled, the check chamber can be opened. At this time, the collection box can be directly disassembled to clean the impurities. Its operation is simple and more convenient when cleaning impurities.
[0011] In a preferred embodiment of a straight-through check valve for easy cleaning of impurities, the impurity collection box has multiple handles arranged in a circumferential array on the inner wall of the opening facing the end of the inlet.
[0012] By adopting the above solution, in order to facilitate the removal of the collection box, a handle can be used to remove it when disassembling the collection box, which will make the disassembly process easier.
[0013] In a preferred embodiment of a straight-through check valve for easy cleaning of impurities, the elastic component includes a bracket with a sliding rod slidably mounted at its center. The end of the sliding rod is connected to the check valve core. A compression spring, which pushes the check valve core toward the inlet, is mounted on the bracket. The compression spring is a frustum-shaped spring. Under the push of the compression spring, the check valve core completely seals the inlet. A removable impurity collection box is installed inside the check chamber.
[0014] In order to achieve elastic pushing of the check valve core, the slide rod is guided by the bracket to slide, and the inlet interface is completely blocked under the push of the compression spring, thereby realizing unidirectional flow from the inlet interface to the outlet interface.
[0015] In a preferred embodiment of a straight-through check valve for easy cleaning of impurities, the bracket is connected to multiple circumferentially arrayed legs at the end facing the water outlet, and the bracket is clamped in the impurity collection box by the legs.
[0016] With the above solution, in order to facilitate the cleaning of impurities inside the collection box, parts such as the bracket and sliding rod can be removed, thereby making it easier to rinse the impurities inside the collection box.
[0017] In a preferred embodiment of a straight-through check valve that facilitates the cleaning of impurities, a sealing gasket is fitted onto the surface of the check valve core facing the inlet interface.
[0018] In order to improve the sealing performance of the check valve core, the above solution uses a removable sealing gasket for installation, which facilitates the replacement of the sealing gasket later.
[0019] After adopting the above technical solution, the beneficial effects of this utility model are:
[0020] 1. This straight-through check valve uses a detachable collection box to fill the check chamber. At this time, all impurities will be concentrated in the collection box. After the front straight-through valve body is disassembled, the check chamber can be opened. At this time, the collection box can be directly removed to clean the impurities. Its operation is simple and more convenient when cleaning impurities.
[0021] 2. To facilitate the removal of the collection box, a handle can be used to remove it when disassembling the collection box, which will make the disassembly process easier;
[0022] 3. In order to achieve elastic pushing of the check valve core, the slide rod is guided by the bracket to slide, and under the push of the compression spring, the water inlet is completely blocked, thereby realizing unidirectional flow from the water inlet to the water outlet.
[0023] 4. To facilitate cleaning impurities inside the collection box, parts such as the bracket and sliding rod can be removed, making it easy to rinse the impurities inside the collection box.
[0024] 5. To improve the sealing performance of the check valve core, a removable sealing gasket is used for installation, which facilitates the replacement of the sealing gasket later. Attached Figure Description

Detailed Implementation
[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] like Figures 1 to 5 As shown, a straight-through check valve for easy cleaning of impurities includes a straight-through check valve body. The body has a check chamber 1 and an inlet port 2 and an outlet port 3 connected to the front and rear of the check chamber 1, respectively. Both the inlet port 2 and the outlet port 3 are threaded holes. A check valve core 4 and an elastic component are installed inside the check chamber 1. The check valve core 4, pushed by the elastic component, completely blocks the inlet port 2, thereby achieving unidirectional flow from the inlet port 2 to the outlet port 3. The straight-through check valve body includes a front straight-through valve body 5 and a rear straight-through valve body 6, which is installed on the front straight-through valve body 5 via threaded disassembly. The check chamber 1 can be opened after the front straight-through valve body 5 is disassembled. A removable impurity collection box 7 is installed inside the check chamber 1. The impurity collection box 7 is interconnected with the inlet port 2 and the outlet port 3 and is completely fitted against the inner wall of the check chamber 1. The check valve core 4 and the elastic component are both located inside the impurity collection box 7. The straight-through check valve uses a detachable collection box 7 to fill the check chamber 1. At this time, all impurities will be concentrated in the collection box 7. After the front straight-through valve body 5 is disassembled, the check chamber 1 can be opened. At this time, the impurities can be cleaned by directly disassembling the collection box 7. Its operation is simple and more convenient when cleaning impurities.
[0034] like Figure 4 As shown, the collection box 7 has multiple handles 8 arranged in a circumferential array welded on the inner wall of the opening facing the end of the water inlet 2. To facilitate the removal of the collection box 7, the handles 8 can be used to remove it when disassembling the collection box 7, making the disassembly process easier.
[0035] like Figure 5 As shown, the elastic component includes a bracket 9, with a sliding rod 10 slidably mounted at the center of the bracket 9. The end of the sliding rod 10 is connected to the check valve core 4. A compression spring 11, which pushes the check valve core 4 towards the water inlet 2, is mounted on the bracket 9. The compression spring 11 is a frustoconical spring. Under the push of the compression spring 11, the check valve core 4 completely blocks the water inlet 2. A removable collection box 7 is installed inside the check chamber 1. In order to achieve elastic pushing of the check valve core 4, the sliding rod 10 is guided by the bracket 9 to slide, and under the push of the compression spring 11, the water inlet 2 is completely blocked, thereby realizing unidirectional flow from the water inlet 2 to the water outlet 3.
[0036] like Figure 5As shown, the bracket 9 has multiple circumferentially arrayed support legs 12 welded to the end facing the water outlet 3. The bracket 9 is clamped in the collection box 7 by the support legs 12. In order to facilitate the cleaning of impurities in the collection box 7, the bracket 9, the slide bar 10 and other parts can be removed, so as to facilitate the rinsing of impurities inside the collection box 7.
[0037] like Figure 5 As shown, a sealing gasket 13 is fitted onto the surface of the check valve core 4 facing the water inlet interface 2. To improve the sealing performance of the check valve core 4, a removable sealing gasket 13 is used for installation, which facilitates the replacement of the sealing gasket 13 in the future.
[0038] The working principle of this utility model:
[0039] In application, the check valve core 4 in the check chamber 1 is connected to the slide rod 10, and the slide rod 10 is guided to slide by the bracket 9. When water flows from the inlet port 2 to the outlet port 3, the check valve core 4 will automatically open under the impact of the water flow; when water flows from the outlet port 3 to the inlet port 2, the check valve core 4 will completely block the inlet port 2 under the push of the compression spring 11, thereby realizing the unidirectional flow of water from the inlet port 2 to the outlet port 3.
[0040] When cleaning impurities, the check chamber 1 is opened by disassembling the front straight valve body 5. At this time, the impurity collection box 7 can be directly removed to clean the impurities. In order to facilitate the cleaning of impurities in the impurity collection box 7, the bracket 9, slide bar 10 and other parts can be removed to facilitate rinsing the impurities inside the impurity collection box 7.
[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
