Description

Technical Field

[0001] The present application belongs to the technical field of secondary water supply systems, and specifically relates to a float valve and a water supply system. Background Art

[0002] At present, urban expansion has caused excessive water consumption during the peak period of water supply. In order to meet the requirements of water consumption during the peak period, the government has spent a huge amount of money to divert water over long distances and adjust the pipe network. However, most studies have taken the water diversion of the municipal main network as the main research object, and have not integrated it well with the secondary water supply end. According to the current national standard "Design Standard for Building Water Supply and Drainage", Article 3.8.8 stipulates that the design volume of the water tank should be determined according to 20% to 25% of the maximum daily water consumption of the building, Article 3.13.9 stipulates that the water tank volume can be determined according to 15% to 20% of the maximum daily domestic water consumption, and Article 3.13.10 stipulates that the water storage design update cycle shall not exceed 48h. In order to meet the above requirements and avoid accidents of water supply interruption during peak periods, designers can only keep the water tank in a state close to full water at all times, that is, as long as the water tank is used, the water inlet pipe will start to infuse water synchronously. In order to meet the requirements of water inlet flow, the diameter of the water inlet pipe is also selected according to the maximum flow at the highest day. During the peak period, the domestic water tanks of each community are in full load. In this way, no matter how the municipal pipe network is adjusted, a good peak-shifting effect can never be achieved. In order to achieve a better peak-shifting effect, it is necessary to control the water inlet flow of the water tank. At present, an electric control flow regulating valve is usually installed on the water outlet main to change the water replenishment volume of the water outlet main. However, such a modification method also requires the installation of an electric control part and the laying of power supply lines, which invisibly increases the modification cost. In addition, there are still problems such as low reliability, uncertainty in adjustment size and time, high investment, and inability to promote on a large scale through electric control.

DETAILED DESCRIPTION

Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

The terms "first", "second", and "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. In addition, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be a connection between the two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present utility model can be understood according to the specific circumstances.

[0022] like Figure 1 As shown, the float valve provided by the embodiment of the utility model includes a valve housing 1, a partition plate 2 and an opening mechanism.

[0023] A water inlet and a water outlet are respectively arranged on both sides of the valve housing 1, and a partition plate 2 is arranged between the water inlet and the water outlet in the valve housing 1, and three water holes 3 are arranged on the partition plate 2, and each of the water holes 3 is correspondingly provided with a group of the opening mechanisms.

[0024] The opening mechanism includes a chamber 17 , a movable rod 4 , a return spring 5 , a valve plate 6 , a limit ring 7 , a liquid infusion tube 8 , a float valve 9 and a float 10 .

[0025] The movable rod 4 is slidably disposed in the valve housing 1 , the return spring 5 is sleeved on the movable rod 4 , the valve plate 6 matched with the water hole 3 is disposed at the lower end of the movable rod 4 , and the limiting ring 7 is disposed at the upper end of the movable rod 4 .

[0026] The upper end of the infusion tube 8 is connected to the top of the valve housing 1, and the float valve 9 is provided at the lower end of the infusion tube 8. The float valve 9 and the float 10 are connected by a connecting rod 11. The limiting ring 7 is provided in the chamber 17, and the upper end of the infusion tube 8 is connected to the chamber 17.

[0027] In this embodiment, a regulating valve 12 is further provided on the valve housing 1 .

[0028] It should be noted that the structure of the opening mechanism is the same as the principle of the piston-type remote-controlled float valve in the prior art, except that three opening mechanisms are arranged in parallel in the present application, and the three opening mechanisms operate independently. The three opening mechanisms respectively control the opening and closing of the three water holes 3, thereby realizing the flow regulation of the float valve. The limit ring 7 is arranged in the corresponding chamber 17, and the infusion tube 8 is connected to the corresponding chamber 17. The setting of the separation chamber 17 is used to ensure that the three opening mechanisms can work independently.

[0029] In this embodiment, the diameters of the three water holes 3 increase sequentially.

[0030] It should be noted that the lower the water level, the higher the system replenishment volume, thereby meeting peak water demand.

[0031] In this embodiment, a stop valve 13 is provided on the infusion tube 8 .

[0032] It should be noted that when the float valve 9 is inspected, the corresponding stop valve 13 is closed. Closing the corresponding stop valve 13 can disconnect its control pipeline, so that the float valve can be inspected.

[0033] like Figure 1 As shown, a water supply system provided by an embodiment of the utility model includes the above-mentioned float valve and a water tank 14, a water inlet pipe 15 and a water outlet pipe 16.

[0035] The floats 10 of the three opening mechanisms corresponding to the three water holes 3 are respectively located at the upper part, the middle part and the lower part of the water tank 14 .

[0036] It should be noted that by setting three opening mechanisms, different water replenishment flows can be formed by different combinations of water supply methods when the liquid level is at different heights, that is, the utility model automatically adjusts the water replenishment amount according to the different liquid levels, thereby solving the problem of excessive water supply flow demand of the municipal pipe network during peak hours, and achieving the effect of staggered water supply. The utility model also improves the water supply pressure of the municipal pipe network, so that the entire pipe network can be in a higher pressure state. The utility model adopts a purely mechanical adjustment method, which is not only reliable in working mode and not prone to failure, but also has a low investment cost and relatively small modification for the existing water supply pipeline, avoiding the existing modification method of setting an electric control flow regulating valve 12 on the water outlet main pipe to change the water replenishment amount of the water outlet main pipe, which has high modification costs and low reliability through electric control.

[0037] In this embodiment, it is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiment, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. The same applies to more than three liquid levels. Therefore, no matter from which point of view, the embodiment should be regarded as exemplary and non-restrictive, and the scope of the present invention is limited by the attached claims rather than the above description, and it is intended that all changes that fall within the meaning and scope of the equivalent elements of the claims are included in the present invention.
