Abstract
Description
Technical Field
[0001] This utility model relates to the field of angle valves, specifically to a water flow indicator angle valve. Background Technology
[0002] Angle valves are common valves used in daily life and are widely applied. They are used to connect to water pipes inside walls. In daily life, water supply may be interrupted due to pipeline maintenance or water tank cleaning, but users cannot directly see the water outage status and need to turn on the tap to verify. Often, after turning on the tap, users forget to turn it off, leading to water waste and the risk of flooding.
[0003] In view of this, the inventor conducted in-depth research on the aforementioned deficiencies in the prior art, which led to the creation of this case. Utility Model Content
[0004] The main purpose of this utility model is to provide a water supply indicator valve that can conveniently indicate the current water supply status.
[0005] To achieve the above objectives, the solution of this utility model is:
[0006] A water flow indicator valve includes a housing and an inner core assembly; the inner core assembly includes a water passage pipe and an axial adjustment part; the housing has a mounting cavity and an inlet and an outlet respectively communicating with the mounting cavity; the axial adjustment part of the inner core assembly is connected to the mounting cavity to adjust the axial position of the water passage pipe, and the water passage pipe of the inner core assembly passes through the inlet.
[0007] An indicator rod is slidably disposed within the axial adjustment part along the axial direction, and a spring is also included to push the indicator rod toward the water inlet; one end of the indicator rod is directly opposite the outlet of the water pipe; when the water supply is stopped, the indicator rod moves toward the water pipe to the first limit position; when the water supply is in progress, the indicator rod moves toward the spring to the second limit position under the impact of the incoming water flow.
[0008] Furthermore, a sealing ring is provided between the outer wall of the indicator rod and the inner wall of the axial adjustment part to maintain a sealed state at all times.
[0009] Furthermore, a water-stop ring is provided at one end of the indicator rod that extends into the mounting cavity. In the first extreme position, the water-stop ring disengages from the axial adjustment part; in the second extreme position, the water-stop ring abuts and seals against the axial adjustment part.
[0010] Furthermore, an indicator block is connected to one end of the indicator rod outside the mounting cavity, and a handle is connected to the axial adjustment part; as the indicator rod moves, the axial relative positions of the indicator block and the handle are different; at the first extreme position, the indicator block abuts against the handle.
[0011] Furthermore, a groove is formed on the handle, and the indicator block extends into the groove; an observation hole is formed on the side of the handle; a first color mark and a second color mark are formed on the side wall of the indicator block, corresponding to the observation hole at the first extreme position and the second extreme position, respectively; the first color mark and the second color mark are different colors.
[0012] Furthermore, the spring is sleeved on the indicator rod and located between the axial adjustment part and the indicator rod; the two ends of the spring respectively abut against the indicator rod and the axial adjustment part along the axial direction.
[0013] Furthermore, a filter screen is provided at one end of the axial adjustment part near the water pipe; one end of the indicator rod moves axially within the space enclosed by the filter screen.
[0014] Furthermore, the axial adjustment part is threadedly connected to the mounting cavity of the housing.
[0015] With the above structure, the water flow indicator valve of this utility model has at least the following beneficial effects:
[0016] 1. When there is water pressure in the installation cavity, the water pressure acts on the end of the indicator rod, overcoming the spring force and keeping the indicator rod in the second limit position. When the water supply is stopped, the water pressure in the installation cavity decreases, and under the action of the spring force, the indicator rod moves towards the water pipe to the first limit position. By observing the position of the indicator rod, the user can understand the current water supply status in the angle valve.
[0017] 2. A sealing ring is provided between the outer wall of the indicator rod and the inner wall of the axial adjustment part to maintain a sealed state, so as to prevent water in the installation cavity from leaking out through the gap between the indicator rod and the axial adjustment part.
[0018] Third, by changing the relative position of the indicator block and the handle, the user can more intuitively observe the current water supply status of the angle valve. Furthermore, through the observation hole and the first and second color marks, the user can observe different colors through the observation hole and thus intuitively understand the current water supply status of the angle valve.

[0025] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.
[0026] like Figures 1 to 4 As shown, this utility model relates to a water flow indicator angle valve, which includes a housing 1 and an inner core assembly. The inner core assembly includes a water passage pipe 2 and an axial adjustment part 3. The housing 1 has a mounting cavity 11 and an inlet 12 and an outlet 13 respectively communicating with the mounting cavity 11. The axial adjustment part 3 of the inner core assembly is connected to the mounting cavity 11 to adjust the axial position of the water passage pipe 2. The water passage pipe 2 of the inner core assembly passes through the inlet 12.
[0027] An indicator rod 4 is slidably disposed within the axial adjustment part 3 along the axial direction, and a spring 43 is also included to push the indicator rod 4 toward the water inlet 12; one end of the indicator rod 4 is directly opposite the outlet of the water pipe 2; when the water is stopped, the indicator rod 4 moves toward the water pipe 2 to the first limit position; when the water is supplied, the indicator rod 4 moves toward the compression spring to the second limit position under the impact of the incoming water flow.
[0028] Thus, in this utility model, when there is water pressure in the mounting cavity 11, the water pressure acts on the end of the indicator rod 4, overcoming the elastic force of the spring 43 and keeping the indicator rod 4 in the second extreme position. Figure 2 As shown; when the water supply is interrupted, the water pressure in the mounting cavity 11 decreases. Under the action of the spring 43, the indicator rod 4 moves towards the water pipe 2 to the first limit position, as shown. Figure 3 As shown. By observing the position of indicator rod 4, the user can understand the current water supply status within the angle valve.
[0029] Preferably, a sealing ring 44 is provided between the outer wall of the indicator rod 4 and the inner wall of the axial adjustment part 3 to maintain a constant seal. The sealing ring 44 prevents water in the mounting cavity 11 from leaking out through the gap between the indicator rod 4 and the axial adjustment part 3.
[0030] Preferably, a water-stop ring 45 is provided at one end of the indicator rod 4 that extends into the mounting cavity 11. In the first extreme position, the water-stop ring 45 disengages from the axial adjustment part 3; in the second extreme position, the water-stop ring 45 abuts against the axial adjustment part 3 for sealing. During normal water supply, the sealing is mainly achieved by the water-stop ring 45 and the end of the axial adjustment part 3. If the water-stop ring 45 fails, the sealing ring 44 serves as the final guarantee of sealing.
[0031] To facilitate user observation of the current water supply status, preferably, an indicator block 42 is connected to one end of the indicator rod 4 located outside the mounting cavity 11, and a handle 41 is connected to the axial adjustment part 3. As the indicator rod 4 moves, the axial relative positions of the indicator block 42 and the handle 41 change; at the first extreme position, the indicator block 42 abuts against the handle 41. By changing the relative position of the indicator block 42 and the handle 41, the user can more intuitively observe the current water supply status of the angle valve.
[0032] Furthermore, a groove 411 is formed on the handle 41, and the indicator block 42 extends into the groove 411; an observation hole 412 is formed on the side of the handle 41; a first color mark and a second color mark are formed on the side wall of the indicator block 42, corresponding to the observation hole 412 at the first and second extreme positions, respectively; the first color mark and the second color mark are different colors. Through the observation hole 412 and the first and second color marks, the user can observe the different colors and intuitively understand the current water supply status of the angle valve. For example, at the first extreme position, the first color mark is red and the second color mark is green at the second extreme position.
[0033] Preferably, the spring 43 is sleeved on the indicator rod 4 and located between the axial adjustment part 3 and the indicator rod 4; the two ends of the spring 43 respectively abut against the indicator rod 4 and the axial adjustment part 3 along the axial direction. In this way, the spring 43 can be simply and cost-effectively installed between the axial adjustment part 3 and the indicator rod 4. The spring 43 can also be installed outside the indicator rod 4, as long as the spring 43 generates a force that pushes the indicator rod 4 towards the water inlet 12.
[0034] Preferably, a filter screen 31 is provided at one end of the axial adjustment part 3 near the water pipe 2; one end of the indicator rod 4 moves axially within the space enclosed by the filter screen 31. By providing the filter screen 31, solid impurities in the water are filtered. When the filter screen 31 needs cleaning, the axial adjustment part can be removed from the housing 1 for cleaning. For example, the axial adjustment part 3 is threadedly connected to the mounting cavity 11 of the housing 1. The threaded connection allows the axial adjustment part 3 to move spirally axially when rotated, and also facilitates disassembly for cleaning of the filter screen 31.
[0035] like Figure 1 and Figure 4 As shown, the water pipe 2 achieves water sealing and water flow in two ways, for example... Figure 1 Water sealing and water flow are achieved through the axial position of the sealing ring 21 fitted on the water pipe 2 relative to the water inlet 12. For example... Figure 4 Water sealing and water flow are achieved by the water pipe 2 abutting against the existing water stop valve 22 inside the pipe.
[0036] Compared with the prior art, the present invention provides an indicator rod 4 in the axial adjustment part 3, and the current water flow status of the angle valve is indicated by the change of the axial position of the indicator rod 4 relative to the axial adjustment part 3.
[0037] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
