Description

Technical Field

[0001] This utility model relates to the field of valve technology, specifically to a valve water circuit changer. Background Technology

[0002] With the improvement of residents' living standards, the health of household water has received increasing attention, and water treatment equipment such as pre-filters, water purifiers, and water softeners have become common configurations in modern home decoration. However, in older residences or already renovated and occupied houses, the installation of such equipment faces significant technical bottlenecks: traditional water system renovations require chiseling walls and creating trenches to re-lay pipes or expanding the reserved space to achieve series installation of equipment. This process has the following drawbacks: chiseling walls involves wall repair and restoration of wall decoration layers, significantly increasing labor and material costs; damaging the structure of load-bearing walls or walls in areas with dense pipes may lead to risks such as leakage and wall cracking; new equipment requires additional space, and exposed pipes or equipment affect the aesthetics of the interior; dust and noise are generated during construction, and multiple coordinations with plumbers, electricians, and masons are required, seriously disrupting normal life.

[0003] In response, some manufacturers have attempted to alleviate installation difficulties by reducing equipment size or optimizing pipe interface compatibility, but these methods still cannot fundamentally avoid wall damage and complex construction issues. Therefore, there is an urgent need for a water system renovation solution that can be deployed quickly without demolishing walls, to meet the water quality upgrade needs of older residences and renovated homes, while also considering economy, safety, and aesthetics. Utility Model Content

[0004] In view of this, this utility model proposes a valve water circuit changer based on the existing shut-off valve on the pipeline, so as to realize the installation of the pre-filter without breaking the wall.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A valve water circuit alterer includes: a valve body inner tube, one end of which is a first inlet end for connecting to the outlet of a shut-off valve, and the other end of which is a first outlet end; and a valve body outer tube, which includes a first outer tube and a second outer tube. The first outer tube is sleeved between the two ends of the valve body inner tube, and the inner walls of the two ends of the first outer tube are sealed to the outer wall of the valve body inner tube, forming an annular flow cavity between the inner wall of the first outer tube and the outer wall of the valve body inner tube. The first end of the second outer tube is disposed on the outer wall of the end of the first outer tube near the first outlet end and communicates with the flow cavity. The outer wall of the end of the first outer tube near the first inlet end is provided with a return hole communicating with the flow cavity. The outer wall of the first outer tube is provided with a first external connecting thread located between the first end of the second outer tube and the return hole.

[0007] To better implement the above technical solution, optionally, the second end of the first water outlet and the second outer pipe are respectively provided with a second external connecting thread.

[0008] Optionally, the diameter of the first external connecting thread is larger than the diameter of the first external tube.

[0009] Optionally, there are multiple reflux holes, which are spaced apart circumferentially along the outer wall of the first outer tube.

[0010] Optionally, an auxiliary nut is fixed to the outer wall of the first outer tube, the auxiliary nut being used to fix the valve water circuit changer to the shut-off valve.

[0011] Optionally, the outer wall of the first water inlet end of the valve body tube is fitted with a waterproof gasket that abuts against the end face of the first outer tube near the return hole.

[0012] A filter installation structure includes any of the above-mentioned valve water circuit changers, and further includes a pre-filter and a booster pump. The inlet end of the pre-filter is connected to a first outlet end through a pipeline, the outlet end of the pre-filter is connected to the inlet end of the booster pump through a pipeline, and the outlet end of the booster pump is connected to the first end of a second outer pipe through a pipeline.

[0013] The beneficial effects of this utility model are:

[0014] This utility model discloses a valve water circuit alterer. The end of the first outer pipe with a reflux hole and the first inlet end of the valve body inner pipe are respectively connected to a stop valve. This connects the first inlet end of the valve body inner pipe to the outlet of the stop valve, and the reflux hole of the first outer pipe to the inlet of the stop valve. Water output from the outlet of the stop valve sequentially passes through the first inlet end of the valve body inner pipe, the valve body inner pipe, the first outlet end of the valve body inner pipe, an external device (such as a filter), the second end of the second outer pipe, the second outer pipe, the first end of the second outer pipe, the flow chamber, and the reflux hole of the first outer pipe before entering the inlet of the stop valve, thus closing the water circuit. By replacing the valve core of the existing stop valve with the valve water circuit alterer, additional equipment can be installed on the existing pipeline without demolishing walls, thereby meeting the upgrade needs of existing houses. Using the valve water circuit alterer not only significantly reduces the cost and difficulty of renovation construction but also reduces damage to house decoration and shortens the construction period.

[0015] The filter installation structure of this utility model allows water output from the outlet of the shut-off valve to be filtered in the pre-filter through the valve body pipe, then pressurized by the booster pump, and then fed into the second external pipe, through the flow chamber and return hole into the inlet of the shut-off valve, thereby filtering the water in the existing pipeline and upgrading the filtration of the existing pipeline without demolishing the wall.

Detailed Implementation

[0023] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments. Identical components are indicated by the same reference numerals.

[0024] Example 1

[0025] Please see Figures 1 to 3 This utility model discloses a valve water circuit changer, including a valve body inner tube 10 and a valve body outer tube.

[0026] The valve body inner tube 10 has a first inlet end 101 at one end, which is used to connect to the outlet of the shut-off valve 60. The other end of the valve body inner tube 10 is a first outlet end 102. The valve body outer tube includes a first outer tube 20 and a second outer tube 30. The first outer tube 20 is sleeved between the two ends of the valve body inner tube 10, and the inner walls of the two ends of the first outer tube 20 are sealed to the outer wall of the valve body inner tube 10, so that an annular flow is formed between the inner wall of the first outer tube 20 and the outer wall of the valve body inner tube 10. The first end of the second outer tube 30 is located on the outer wall of the end of the first outer tube 20 near the first water outlet 102 and communicates with the water flow chamber 40. The outer wall of the end of the first outer tube 20 near the first water inlet 101 is provided with a return hole 201 that communicates with the water flow chamber 40. The outer wall of the first outer tube 20 is provided with a first external connecting thread 202 located between the first end of the second outer tube 30 and the return hole 201. The first external connecting thread 202 is used to connect with the internal thread of the shut-off valve 60.

[0027] According to an embodiment of this utility model, a valve water circuit modifier is provided. The end of the first outer pipe 20 with a return hole 201 and the first water inlet 101 of the valve body pipe 10 are respectively connected to a shut-off valve 60, so that the first water inlet 101 of the valve body pipe 10 is connected to the water outlet of the shut-off valve 60, and the return hole 201 of the first outer pipe 20 is connected to the water inlet of the shut-off valve 60. Water output from the water outlet of the shut-off valve 60 passes sequentially through the first water inlet 101 of the valve body pipe 10, the valve body pipe 10, the first water outlet 102 of the valve body pipe 10, and the external device. (Such as a filter), the second end of the second outer pipe 30, the second outer pipe 30, the first end of the second outer pipe 30, the water flow chamber 40, and the return hole 201 of the first outer pipe 20 enter the inlet hole of the shut-off valve 60 to achieve water circuit closure. By replacing the valve core of the existing shut-off valve 60 with a valve water circuit changer, additional equipment can be installed on the existing pipeline without demolishing the wall, thereby meeting the upgrade needs of the existing house. The use of a valve water circuit changer not only greatly reduces the cost and difficulty of renovation and construction, but also reduces the damage to the house decoration and shortens the construction cycle.

[0028] In the embodiments of this utility model, the second ends of the first water outlet 102 and the second outer pipe 30 are respectively provided with second external connecting threads. The use of second external connecting threads facilitates the connection of the second ends of the first water outlet 102 and the second outer pipe 30 to external equipment, which improves the versatility and convenience of equipment installation, can quickly adapt to a variety of external equipment, reduce installation and debugging time, and improve overall installation efficiency.

[0029] In the embodiments of this utility model, the inner walls of both ends of the first outer tube 20 and the outer wall of the valve body tube 10 can be connected as one piece by welding or integral forming. This makes it easier to install the valve water circuit changer on the shut-off valve 60. The welding or integral forming process eliminates the connection gaps between components, effectively prevents water leakage, enhances the overall structure and pressure resistance, and extends the service life of the equipment.

[0030] In this embodiment of the invention, the diameter of the first external connecting thread 202 is larger than the diameter of the first outer tube 20. A jacking nut 203 is fixed to the outer wall of the first outer tube 20. The jacking nut 203 is used to fix the valve water circuit changer onto the shut-off valve 60. By rotating the jacking nut 203 with a wrench, the valve water circuit changer is driven, causing the first external connecting thread 202 to engage or disengage from the internal thread of the shut-off valve 60. This allows the valve water circuit changer to be installed on or removed from the shut-off valve 60. The first external connecting thread 202 and the jacking nut 203 simplify the installation and removal of the valve water circuit changer, reducing the labor intensity of installers. Simultaneously, the threaded connection ensures stability after installation, preventing loosening during use.

[0031] In the embodiments of this utility model, there are multiple return holes 201, which are spaced apart circumferentially along the outer wall of the first outer tube 20. Preferably, there are three or four return holes 201. Multiple return holes 201 that are evenly distributed circumferentially increase the water flow area, reduce resistance, and make the water flow back evenly to the inlet of the shut-off valve, avoiding excessive local pressure and improving circulation efficiency.

[0032] In an embodiment of this utility model, a waterproof gasket 50 is provided on the outer wall of the first water inlet end 101 of the valve body tube 10, which abuts against the end face of the first outer tube 20 near the return hole 201. The waterproof gasket 50 can improve the waterproof performance between the water outlet and the water inlet of the shut-off valve 60, and prevent direct communication between the water outlet and the water inlet of the shut-off valve 60.

[0034] like Figure 4 and Figure 5 As shown, this embodiment 2 provides a filter installation structure based on embodiment 1, including the valve water circuit changer in embodiment 1, and also includes a pre-filter 70 and a booster pump 80. The inlet end of the pre-filter 70 is connected to the first outlet end 102 through a pipeline, the outlet end of the pre-filter 70 is connected to the inlet end of the booster pump 80 through a pipeline, and the outlet end of the booster pump 80 is connected to the first end of the second outer pipe 30 through a pipeline.

[0035] The filter installation structure of this utility model embodiment allows water output from the outlet of the shut-off valve 60 to be filtered by the valve body pipe 10, then pressurized by the booster pump 80, and then input into the second outer pipe 30, through the water flow chamber 40 and the return hole 201 into the inlet of the shut-off valve 60, thereby filtering the water in the existing pipeline and upgrading the filtration of the existing pipeline without demolishing the wall.
