Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a water-saving intelligent valve. Background Technique

[0002] There are various types of valves, among which there are intelligent valves that can not only control the opening and closing of the valves, but also monitor the flow rate, flow velocity, etc. in real time.

[0003] After retrieval, the intelligent valve announced with the publication number CN212775687U can perform leakage detection, automatically close the pipeline in time to prevent property losses and avoid potential safety hazards. However, when the valve leaks, although it can be detected in time, during the process of the maintenance personnel coming to check, the valve is still in the leaking state, resulting in waste of water resources. Content of the Utility Model

[0004] The purpose of the utility model is to solve the defects existing in the prior art, and to propose a water-saving intelligent valve.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

A baffle is welded on the circumferential inner wall of the connecting pipe. A water passing hole penetrating through the baffle is opened on one side of the baffle. A fixing frame is welded on the circumferential inner wall of the connecting pipe. A blocking frame is sleeved between the circumferential inner walls of the fixing frame. The blocking frame is in contact with the baffle, and the diameter of the contact surface between the blocking frame and the baffle is larger than the diameter of the water passing hole. A spring is fixed on one side of the blocking frame by bolts. An adjusting component for changing the elastic force of the spring is arranged on one side of the fixing frame.

[0007] As a further scheme of the utility model, the adjusting component includes a threaded groove opened on one side of the fixing frame. An external threaded ring is in threaded connection in the threaded groove, and the external threaded ring is in contact with the spring.

[0008] As a further scheme of the utility model, an insertion ring is welded on one side of the blocking frame. A groove is opened on one side of the baffle, and the insertion ring is inserted into the groove.

[0012] The beneficial effects of the present utility model are as follows:

[0013] 1. By providing a baffle and a retaining frame, when the valve body leaks, since the water flow pressure of the leak is small, the water flow will be blocked by the retaining frame and remain in the space between the retaining frame and the valve body, thus avoiding the waste of water flow during the inspection by maintenance personnel and improving the water-saving performance of the valve.

[0014] 2.

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. The described embodiments are only a part of the embodiments of the present utility model, not all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present utility model.

[0022] Refer to Figures 1-4, A water-saving intelligent valve, including a valve body 1. A connecting pipe 2 is provided on one side of the valve body 1. Connecting heads 3 are provided on both the connecting pipe 2 and one side of the valve body 1. The valve can be installed in an external pipeline through the connecting head 3. A baffle 4 is welded to the circumferential inner wall of the connecting pipe 2. A water passing hole 5 penetrating the baffle 4 is opened on one side of the baffle 4. A fixing frame 6 is welded to the circumferential inner wall of the connecting pipe 2. A blocking frame 7 is sleeved between the circumferential inner walls of the fixing frame 6, and the blocking frame 7 is in contact with the baffle 4. And the diameter of the contact surface between the blocking frame 7 and the baffle 4 is larger than the diameter of the water passing hole 5. A spring 10 is fixed to one side of the blocking frame 7 by bolts. An adjusting component for changing the elastic force of the spring 10 is provided on one side of the fixing frame 6. When in use, the device is installed on a water pipe, and the valve body 1 is opened. Water flows into the connecting pipe 2 from the valve body 1. The water flow will impact the blocking frame 7, causing the blocking frame 7 to move backward, so that the blocking frame 7 is separated from the baffle 4. At this time, the water flow will flow through the gap between the blocking frame 7 and the baffle 4 from the water passing hole 5 and flow through the gap between the fixing frame 6 and the connecting pipe 2, thus completing the normal water flow. During the process of the blocking frame 7 moving backward, the blocking frame 7 will squeeze the spring 10 to contract and generate elastic force. When the valve body 1 is closed, the spring 10 will reset and drive the blocking frame 7 to reset, so that the blocking frame 7 is in contact with the baffle 4 to seal the connecting pipe 2. When the valve body 1 leaks, due to the relatively small pressure of the leaked water flow, the water flow will be blocked by the blocking frame 7 and remain in the space between the blocking frame 7 and the valve body 1, thus avoiding the waste of water flow during the inspection by maintenance personnel and improving the water-saving performance of the valve.

[0023] In the present utility model, the adjusting component includes a threaded groove 13. The threaded groove 13 is opened on one side of the fixing frame 6. An external threaded ring 12 is threadedly connected in the threaded groove 13, and the external threaded ring 12 is in contact with the spring 10. Rotate the external threaded ring 12 to move the external threaded ring 12, thereby squeezing the spring 10, changing the pressure required for the blocking frame 7 to move, and thus adapting to different water pressures, improving the applicability of the valve.

[0024] Among them, an insertion ring 11 is welded to one side of the blocking frame 7. A groove 8 is opened on one side of the baffle 4. The insertion ring 11 is inserted into the groove 8 to assist in sealing between the blocking frame 7 and the baffle 4, thus preventing the water flow from flowing through the gap between the blocking frame 7 and the baffle 4 and improving the sealing performance of the valve.

[0025] Among them, a diversion frame 9 is fixed to one side of the baffle 4 by bolts, and the circumferential outer wall of the diversion frame 9 is fixed to the connecting pipe 2. The liquid passing holes of the diversion frame 9 have the same size as the water passing holes 5. During the process of water flow, the water flow will be diverted by the diversion frame 9 into the water passing holes 5, thus preventing the water flow from directly impacting the baffle 4 and causing deformation and damage to the baffle 4, and improving the service life of the valve.

[0026] Working principle: When in use, install the device on the water pipe, open the valve body 1, and water flows into the connecting pipe 2 from the valve body 1. The water flow will impact the blocking frame 7, causing the blocking frame 7 to move backward, so that the blocking frame 7 is disengaged from the baffle 4. At this time, the water flow will flow through the water passing holes 5 through the gap between the blocking frame 7 and the baffle 4, and flow through the gap between the fixing frame 6 and the connecting pipe 2, thus completing the normal water flow circulation. During the process of the blocking frame 7 moving backward, the blocking frame 7 will squeeze the spring 10 to contract and generate elastic force. When the valve body 1 is closed, the reset of the spring 10 will drive the blocking frame 7 to reset, so that the blocking frame 7 contacts the baffle 4 to seal the connecting pipe 2. When the valve body 1 leaks, due to the relatively small pressure of the leaked water flow, the water flow will be blocked by the blocking frame 7 and remain in the space between the blocking frame 7 and the valve body 1, thus avoiding the waste of water flow during the inspection by maintenance personnel and improving the water saving performance of the valve.

[0027] Finally, it should be noted that for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
