Description

Technical Field

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

[0002] Non-negative pressure water supply equipment is a pressurized water supply unit that is directly connected to the municipal water supply network. It is connected in series with the municipal water supply network based on the residual pressure of the municipal water supply network to ensure that the municipal water supply network pressure is not less than the set protection pressure of the secondary pressurized water supply equipment. Non-negative pressure water supply equipment is also called pipe network superimposed water supply equipment. There are mainly tank-type non-negative pressure water supply equipment and box-type non-negative pressure water supply equipment on the market.

[0003] Tank-type non-negative pressure water supply equipment can effectively use the gravity and pressure of water to meet the water supply needs of multiple floors through the water storage tank installed in the equipment. Compared with the traditional water pump water supply system, tank-type non-negative pressure water supply equipment can control the use time and water supply volume of the pump within the optimal range, thereby achieving energy-saving and high-efficiency effects.

[0004] However, the tank-type water supply equipment needs to filter the water source when supplying water. Among the common filtering methods, one is to install the filter plate inside the turbulence tank, which not only affects the water storage capacity of the turbulence tank, but also requires closing the valve to clean and replace the baffle, which not only affects the water supply of the equipment, but also is inconvenient to operate; another method is to add a filter unit to the outside of the tank body for connection. This practice increases the volume of the equipment and the space occupancy rate, and also increases the cost of using the equipment. Therefore, those skilled in the art provide an integrated tank-type non-negative pressure water supply equipment to solve the problems raised in the above background technology. Utility Model Content

[0005] 1. Technical issues to be resolved

[0006] In view of the deficiencies in the prior art, the utility model provides an integrated tank-type non-negative pressure water supply equipment to solve the problem that the tank-type water supply equipment needs to filter the water source when supplying water. In the common filtering method, the filter plate is generally installed inside the pressure-stabilizing tank and the constant pressure tank, which not only affects the water storage capacity of the tank body, but also makes the subsequent cleaning and replacement of the partitions inconvenient. In another method of adding a filtering unit to the outside of the tank body, the volume of the equipment increases, resulting in an increase in space occupancy and an increase in the use cost of the equipment.

[0007] (II) Technical solution

[0008] To achieve the above purpose, the utility model provides the following technical solutions: an integrated tank-type non-negative pressure water supply device, comprising a flow stabilizing tank body, the upper part of the flow stabilizing tank body is connected to a water inlet pipe, a negative pressure suppressor is installed at the connection between the water inlet pipe and the flow stabilizing tank body, the lower part of the flow stabilizing tank body is connected to a water outlet pipe, the water outlet pipe is connected to a mounting seat, and a water pump is installed at the lower end of the water outlet pipe, and the water pump is used for conveying water;

[0009] Bolts are threadedly connected on the upper and lower sides of the mounting seat, a through groove is horizontally opened in the mounting seat, an insert block is horizontally inserted in the through groove, two water grooves are opened on the insert block, a support ring is installed at the bottom opening of the water groove, a threaded ring is threadedly connected at the upper opening of the water groove, a filter element is arranged between the support ring and the threaded ring, and threaded holes are opened on the upper and lower sides of the insert block.

[0010] Preferably, the inner diameter of the water trough is the same as the inner diameter of the water outlet pipe. When the water trough is aligned with the water outlet pipe, the water source can be filtered through the filter element.

[0011] Preferably, the bottom of the filter element is in contact with the support ring, and the upper part of the filter element is in pressure contact with the threaded ring, and the filter element can be replaced after the threaded ring is screwed out.

[0012] Preferably, baffles are provided at both ends of the plug block, and the baffles are plugged into the side ends of the mounting seat. The provision of the baffles can avoid the problem of misalignment between the water trough and the water outlet pipe.

[0013] Preferably, a movable handle is inserted into the top of the bolt, and the bolt is threadedly connected to the threaded hole. Through the arrangement of the movable handle and the bolt, after replacing the water trough and the filter element, the plug and the mounting seat can be tightened to avoid gaps.

[0014] (III) Beneficial effects

[0015] Compared with the prior art, the utility model provides an integrated tank-type non-negative pressure water supply device, which has the following beneficial effects:

[0016] Through the design, the plug is moved so that the baffle at one end of the plug contacts the side end of the mounting seat. At this time, one of the water troughs is connected to the water outlet pipe, so that the water outlet pipe can normally transport water and the water is filtered by the filter element. After the filter element has been used for a certain period of time, the filter element is placed in another water trough located on the side of the water outlet pipe, and the plug is pulled to one side so that the water trough with the filter element just replaced is connected to the water outlet pipe again, thereby achieving the effect of replacing the filter element. This method of replacing the filter element does not require shutting down the water supply equipment, and the filter element can be replaced with less impact. The process of replacing the filter element is quick and convenient, and because the filtering mechanism is integrally connected to the water outlet pipe, the volume is small, and the negative pressure suppression device, the filtering mechanism and the conveying mechanism are integrated with the tank body, which will not affect the water storage capacity of the stabilizing tank while reducing space occupancy.
