Description

Technical Field

[0002] The function of a check valve is to allow the medium to flow in one direction only and prevent reverse flow. Usually this type of valve works automatically. Under the pressure of the fluid flowing in one direction, the valve disc opens; when the fluid flows in the opposite direction, the fluid pressure and the self-reclosing valve disc act on the valve seat to cut off the flow. Among them, the internal thread check valve and butterfly check valve belong to this type of valve, which includes swing check valves and lift check valves.

[0003] However, there is a problem with the existing water stop valve. If the air pressure in the pipeline is unstable, the valve core will be frequently opened and closed.

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only 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.

[0016] See also Figure 1 to Figure 2 The utility model provides an embodiment: a magnetic water stop valve, which is used to connect a pipeline, which is responsible for liquid transportation, and includes an inlet valve body 1, a two-way valve body 2 and a ball valve core 3. The inlet valve body 1 is installed in conjunction with the two-way valve body 2 to form a water stop valve structure, and a cavity is left between the inlet valve body 1 and the two-way valve body 2, and the ball valve core 3 is located in the cavity. A soft rubber part 4 is installed near the inner pipe mouth of the inlet valve body 1, and an annular magnet 42 is arranged in the soft rubber part 4. The soft rubber part 4 is provided with an arc groove 41 whose shape is adapted to the ball valve core 3, and the ball valve core 3 can be magnetically adsorbed with the annular magnet 42.

[0017] Under normal conditions, the ball valve core 3 is adsorbed in the arc groove 41 through the annular magnet 42, overcoming the unstable air pressure in the pipeline, forming a blocking structure, preventing water from flowing back, and achieving a water-stopping effect.

[0018] Furthermore, the outer side of the ball head valve core 3 is coated with a soft rubber layer 31 , and the soft rubber layer 31 and the soft rubber component 4 are in contact and fit with each other, thereby improving the sealing effect and preventing the water flow from corroding the ball head valve core 3 .

[0019] In this embodiment, the ball head valve core 3 is made of metal iron; the above is only an example of one embodiment of the ball head valve core 3, and does not limit the ball head valve core 3 to be made of other magnetic materials.

[0020] A first branch 21 and a second branch 22 are provided in the two-way valve body 2. The first branch 21 has the same pipeline direction as the feed valve body 1. The second branch 22 forms an angle with the first branch 21, and the end of the second branch 22 is sealed. The second branch 22 can allow the ball head valve core 3 to enter. The diameter of the first branch 21 is smaller than the diameter of the ball head valve core 3.

[0021] In the output state, water flows into the cavity from the outside of the inlet valve body 1, and the water pressure opens the ball valve core 3. At this time, the inlet valve body 1 is connected with the first branch 21. At the same time, the ball valve core 3 cannot enter the first branch 21. Under the action of water pressure, the ball valve core 3 moves to the end of the second branch 22, which does not affect the connection between the inlet valve body 1 and the first branch 21, thereby achieving the effect of water flow transportation.

[0022] When the water flow stops, the water pressure disappears, the ball valve core 3 rolls into the cavity under the action of gravity, and is adsorbed in the arc groove 41 through the annular magnet 42 to prevent the water flow from flowing back.

[0023] Furthermore, the axis center of the first branch 21 is higher than the axis center of the inlet valve body 1 .

[0024] An arc-shaped slope 23 is also provided in the two-way valve body 2. The arc-shaped slope 23 and the arc-shaped groove 41 form a locking structure for fixing the ball head valve core 3. The locking structure can improve the fixing effect of the ball head valve core 3, further improve the sealing effect between the ball head valve core 3 and the soft rubber part 4, and at the same time reduce the misalignment adsorption between the ball head valve core 3 and the soft rubber part 3, thereby preventing the sealing effect caused by misalignment adsorption.

[0025] A plurality of flow holes 43 are evenly arranged on the soft rubber part 4, and the plurality of flow holes 43 all penetrate the arc groove 41. The plurality of flow holes 43 are flow channels for water flow. At the same time, the plurality of flow holes 43 form a filter structure to prevent foreign matter from flowing into the pipeline and clogging it. Even if it is blocked, the blocked position is the water stop valve, which can be cleaned by disassembling the water stop valve, which is convenient for later maintenance.

[0026] Furthermore, the soft plastic part 4 covering the annular magnet 5 can further improve the rigidity of the soft plastic part 4 and prevent the soft plastic part 4 from being deformed due to unstable air pressure and water pressure.

[0027] The soft rubber part 4 is fixedly installed with the inlet valve body 1 by means of screws.

[0028] The inlet valve body 1 and the two-way valve body 2 are fixedly installed by screws, and a sealing ring gasket 6 is arranged between the inlet valve body 1 and the two-way valve body 2, which further improves the sealing effect of the water stop valve.

[0029] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
