Description

Technical Field

[0001] The utility model relates to the technical field of water supply equipment, in particular to non-negative pressure water supply equipment. Background Art

[0002] When the non-negative pressure water supply equipment is in use, the pressurized water supply unit of the non-negative pressure water supply equipment is directly connected to the municipal water supply network, so that the non-negative pressure water supply equipment can be connected in series with the municipal water supply network based on the residual pressure of the municipal network to supply water, thereby realizing non-negative pressure water supply, effectively adjusting the water volume according to the water demand of residents, and improving people's user experience.

[0003] The non-negative pressure water supply equipment is mainly composed of a flow stabilizing tank, a water inlet pipe, a drain pipe, a delivery pipe and valves. The valve is mainly arranged at the connection between two adjacent groups of pipe bodies. For valves that have been used for a long time, the rubber seals inside the valve will wear out, causing gaps to appear at the valve. Therefore, when tap water passes through the valve at the connection between the two groups of pipe bodies, part of the tap water will leak into the external environment through the gaps at the valve. The non-negative pressure water supply equipment is mainly arranged in the factory. The factory personnel cannot monitor whether the equipment has leaks at any time, resulting in the non-negative pressure water supply equipment with leaks cannot be discovered in the shortest time, affecting the stable operation of the non-negative pressure water supply equipment. In view of the shortcomings of the existing technology, we propose a non-negative pressure water supply equipment to solve the above problems. Utility Model Content

[0027] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0028] The embodiment of the present application solves the problem that valves connecting two adjacent groups of pipes in non-negative pressure water supply equipment have leakage and cannot be detected and solved in time by providing a non-negative pressure water supply equipment, thereby realizing real-time monitoring of the leakage of valves connecting two adjacent groups of pipes in negative pressure water supply equipment.

[0029] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0030] The embodiment of the utility model discloses a non-negative pressure water supply device.

[0031] According to the attached Figure 1-4 As shown, it includes a base 1, a simmering tank 11, a drain pipe 13 and a delivery pipe 2 arranged between the simmering tank 11 and the drain pipe 13, a valve 21 is arranged on the outside of the delivery pipe 2, and a water inlet pipe 12 is arranged on the top of the simmering tank 11. The base 1, the simmering tank 11, the water inlet pipe 12, the drain pipe 13, the delivery pipe 2 and the valve 21 constitute a tank-type non-negative pressure water supply equipment. When it is used, the tank-type non-negative pressure water supply equipment is directly connected to the municipal water supply network, and then the tank-type non-negative pressure water supply equipment is used. The residual pressure of the municipal water supply network transports the water to the water supply pipeline, that is, one end of the municipal water supply network pipe body is connected to the water inlet pipe 12 on the stabilizing tank 11, and then the water enters the stabilizing tank 11, and then is transported to the drain pipe 13 through multiple groups of delivery pipes 2. The drain pipe 13 is connected to the residential water pipe, so that the water can be transported to the residents through the drain pipe 13. When the residual pressure of the municipal water supply network meets the user's water supply requirements, the tank-type non-negative pressure water supply equipment can automatically enter a dormant state.

[0032] A detection mechanism 3 is provided on the outside of the delivery pipe 2 near the valve 21. The connection parts of two adjacent groups of delivery pipes 2 will be connected through the valve 21. When the water passes through the inside of the valve 21 at the delivery pipe 2, the detection mechanism 3 can automatically detect whether there is a water leakage at the valve 21. However, the detection mechanism 3 is not limited to being set at the delivery pipe 2. The specific number and specific setting position of the detection mechanism 3 are adjusted accordingly according to the different structures of the tank-type non-negative pressure water supply equipment. The detection mechanism 3 includes a detection bucket 31. The interior of the detection bucket 31 is fixedly connected to an inner ring 36. The inner wall of the inner ring 36 is fixedly connected to the outer wall of the delivery pipe 2, and the detection bucket 31 is located below the valve 21. On the other hand, a water droplet sensing plate 32 is arranged inside the detection bucket 31, and an energy supply device 33 is arranged on the top of the base 1. Multiple groups of water droplet sensing plates 32 are electrically connected to the energy supply device 33 through the provided cables, and multiple groups of water droplet sensing plates 32 are adapted to the receiving terminals. When the valve 21 at the connection of the two groups of delivery pipes 2 leaks, the water will drip onto the water droplet sensing plate 32 under the action of gravity. At this time, the water droplet sensing plate 32 automatically detects the water body, and the detection results will be automatically transmitted to the receiving terminal adapted thereto. The receiving terminal is not specifically drawn in the accompanying drawings, so that the inspection personnel holding the receiving terminal can solve the valve 21 leakage problem in time.

[0033] The drain port 34 is provided on the outer wall of the detection bucket 31, and the scraper 35 is rotatably arranged on the top of the water drop sensor plate 32, and one end of the scraper 35 is rotatably arranged on the outer wall of the inner ring 36, and the inner wall of the inner ring 36 is connected to the outer wall of the conveying pipe 2, as shown in the attached figure. Figure 4 As shown, one end of the drain port 34 is located above the water drop sensor plate 32, so that when the scraper 35 rotates along the inner ring 36, the scraper 35 can collect the water accumulated on the water drop sensor plate 32, and the collected water can be discharged through the drain port 34 in a centralized manner, so as to avoid affecting the accurate detection of water leakage by the water drop sensor plate 32 in the later stage.

[0034] A fixed shell 4 and a movable shell 41 are provided on the top of the detection bucket 31, and the fixed shell 4 and the movable shell 41 are rotatably connected. A screw 42 for locking therebetween is provided. The fixed shell 4 is fixedly arranged on the top of the detection bucket 31, and one end of the fixed shell 4 and the movable shell 41 are sleeved on the outer wall of the conveying pipe 2. By setting the fixed shell 4 and the movable shell 41, the open end of the detection bucket 31 can be blocked, and the valve 21 can be blocked at the same time, so that the internal equipment of the detection bucket 31 and the valve 21 can be protected, and objects in the external environment can be prevented from falling onto the water drop sensor plate 32, affecting the accurate sensing of the water body by the water drop sensor plate 32.

[0035] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention.
