Problems solved by technology

[0003] At present, the pre-filters on the market have a backflushing function, that is, the interior of the filter is self-cleaned by water pressure to prevent impurities from accumulating in the filter membrane of the filter, but the process of backflushing involves water valves This will lead to the occurrence of the water hammer effect. The water hammer effect means that when the open valve is suddenly closed or the closed valve is suddenly opened, the water flow will generate shock waves under the action of inertia, destroying the valve and the water pump. When flushing, the water flow will damage the pipe connection and the water valve. After repeated use, it will cause water leakage and rupture at the connecting pipe. Some filters with poor materials will directly burst the pipe and collapse.

Embodiment 1

[0025] See Figure 1 ~ 3 , A pre-regulatory renapper filter includes a filter chamber 4, a filter film 5, a threaded port 6, a pressure relief hole 7 sealing column 9, and a shut-off valve 16, wherein the filter film 5 for water purification is mounted in the shell The middle portion of the body 1, the outer side of the filter membrane 5 is provided with a filter cavity 4, and the filter film 5 is provided with a threaded port 6, and the thread of the threaded port 6 is provided with a pressure relief hole 7, and the threaded port 6 is provided with a sealing filter. 5 The sealing column 9, and the right side of the housing 1 is provided with a shut-off valve 16 for regulating.

[0026] The housing 1 is provided on the left side of the water supply interface 2, and the water supply pipe 3 is attached to the right side of the water supply interface 2, and the water supply interface 2 is connected to the housing 1, and the feed pipe 3 is connected to the filter film 5 The base 8 is p...

Embodiment 2

[0030] See Figure 4 , A pre-stress-stamping filter is the same as in Example 1, and the filter film 5 is improved, and a card slot 19 is attached to the end of the water pipe 3, and the filter film 5 is mounted on the filter shell 20. In the upper, the filter case 20 is provided with a threaded end 21 between the casing 1, and the filter case 20 is fixed to the housing 1 by the threaded end 21.

[0031] The working principle of the present invention is that when the filter film 5 needs to be replaced, the base 8 is first removed from below, and then the filter case 20 is screwed from the housing 1, and the filter film 5 is replaced. After replacement is completed. The filter case 20 is inserted into the housing, so that the top of the filter case 20 is embedded in the card tank 19, then tighten the threaded end 21, and then tighten the base 8 up, and the replacement of the filter film 5 is completed.

[0032] An advantage of this embodiment is that by removable filter case 20, the...

Abstract

The invention discloses a pre-stabilized recoil filter, which belongs to the technical field of central water distribution. The filter membrane is installed in the middle of the housing, the outside of the filter membrane is provided with a filter chamber, the bottom of the filter membrane is provided with a threaded port, the thread of the threaded port is provided with a pressure relief hole, and the bottom of the threaded port is provided with a sealing column for sealing the filter membrane , The right side of the housing is provided with a shut-off valve for pressure stabilization, a base is provided under the filter membrane, a sealing column is fixedly installed on the base, and a drainage hole is opened at the bottom of the base. The present invention installs a sealing column and a shut-off valve on the pre-filter, which can effectively reduce the water hammer effect generated when the filter is recoiled and cleaned, and prevent the water hammer from destroying the joint and causing water leakage and pipe burst.

Description

Technical field [0001] The present invention relates to the field of centralized water distribution techniques, and in particular, to a pre-regulator reboot filter. Background technique [0002] The central water distribution system is a water distribution device that connects the indoor water appliance by the water pipeline, which first needs to be pretreated in the indoor water source during the installation of the water distribution device. Impurity and trace metallic elements cause blockage and corrosion of pipelines, affecting the service life of water appliances, thereby installing the pre-filter at the water source, preliminary purification of the water source. [0003] At present, the front filters on the market have a rebound function, that is, self-cleaning inside the filter by water pressure, preventing impurities from accumulating in the filter of the filter, but the water valve is involved in the process of repeating The opening and closing, this will cause the hamme...
