Detailed Description
The invention is further illustrated below with reference to the figures and examples.
Example 1
A flow regulator, comprising:
the flow regulating valve comprises a body 1, wherein a normally open flow passage 11 and an elastically deformable throttling part 12 are arranged in the body 1; the throttling part 12 is matched with the normally open flow channel 11 to change the water passing area of the normally open flow channel 11 by utilizing the self-deformation characteristic under the action of water pressure so as to realize throttling; and
at least one bypass flow channel 2 and an inseparable manual adjustment part 3; the water passing area of the bypass flow passage 2 is adjusted by the manual adjusting portion 3.
In this embodiment, the throttling portion 12 is an annular elastic ring made of an elastic material. The bottom of the body 1 is provided with at least one through hole 13 to form the normally open flow channel 11, and the body 1 is also internally provided with an adjusting and forming part 14; the adjusting forming portion 14 is matched with the annular elastic ring, so that the annular elastic ring partially covers the through hole 13, and the adjusting forming portion 14 is of a concave-convex structure arranged on the inner periphery of the body.
When the water pressure is higher, the water flow extrudes the annular elastic ring from top to bottom; the part of the annular elastic ring abutting against the convex part does not deform, and the part corresponding to the concave part deforms towards the concave part, so that the area of the annular elastic ring for shielding the through hole 13 is increased, and the flow area of the normally-open flow passage 11 is reduced. This achieves throttling at high water pressures. When the water pressure is smaller, the part of the annular elastic ring abutting against the convex part does not deform, and the part corresponding to the concave part deforms back to the concave part, so that the area of the annular elastic ring shielding the through hole 13 is reduced, and the flow area of the normally-open flow channel 11 is increased. This achieves a large flow rate at low water pressure.
The manual adjusting part 3 is an adjusting valve; both ends of the bypass flow passage are provided with an upper opening 31 and a lower opening 32 which are communicated with each other to form the bypass flow passage 2; the regulating valve is provided with a rotary groove 33.
A lug 15 matched with the rotating groove 33 is arranged in the body 1; when the regulating valve is turned, the cam 15 is continuously moved between the first position and the second position.
A lower channel 16 is arranged in the body 1; when the lug 15 is located at the first position, the lower channel 16 is communicated with the bypass flow channel 2, and the bypass flow channel 2 is completely opened; when the lug 15 is located at the second position, the lower channel 16 and the bypass flow channel 2 are staggered, and the bypass flow channel 2 is completely closed; when the projection 15 is located between the first position and the second position, the lower channel 16 is partially communicated with the bypass flow channel 2, and the bypass flow channel 2 is partially opened.
When the user feels that the current water flow is too large or too small, the regulating valve can be rotated to change the water flow, the regulation of which is also linear, since the projection 15 is continuously moved between the first and second positions. The user can make precise adjustments to the amount of water. Therefore, the passive regulation mode that the traditional flow regulator only depends on water pressure regulation is overcome, and the water quantity can be regulated by a user. Therefore, the water pump can be applied to various regions with different water pressures.
In this embodiment, the top of governing valve is equipped with the instruction arrow head, and the body is equipped with a sign. When the regulating valve is turned to the point where the indication arrow points to the flag, the bypass passage 2 is in a fully opened state. This further facilitates the user to know the current operating state of the flow regulator.
Example 2
This example differs from example 1 in that: the manual adjusting part 3 is an adjusting valve; the regulating valve is internally provided with a bypass flow channel 2, and the side wall of the bypass flow channel 2 is provided with a through flow hole 31.
An accommodating cavity 17 matched with the regulating valve is arranged in the body 1; one end of the accommodating cavity 17 is communicated with the bypass flow channel 2; the regulating valve continuously moves from a first position to a second position in the accommodating cavity 17; when the regulating valve is located at the first position, the through flow hole 31 is communicated with the normally open flow channel 11, the bypass flow channel 2 is opened, and water flows out from the bottom end of the accommodating cavity 17; when the regulating valve is located at the second position, the through hole 31 is staggered with the normally open flow channel 11, and the bypass flow channel 2 is closed; when the regulating valve is located between the first position and the second position, the through-flow hole 31 is partially communicated with the normally open flow passage 11, and the bypass flow passage 2 is partially opened.
In this embodiment, the adjusting valve is in threaded fit with the accommodating cavity 17, a groove 32 is formed at the top end of the adjusting valve, and the adjusting valve can be rotated by inserting a tool such as a screwdriver.
The bypass flow passage 2 and the normally open flow passage 11 are independent from each other in embodiment 1, but the bypass flow passage 2 and the normally open flow passage 11 communicate with each other when opened in this embodiment. Therefore, another design concept is provided, and the rest is the same as that of embodiment 1, and is not described again.
Example 3
This example differs from example 1 in that: the manual adjusting part 3 is an elastic plug.
A through hole 18 is arranged in the main body 1 to form the bypass flow channel 2; when the elastic plug is plugged into the through flow hole 18 to form interference fit, the bypass flow channel 2 is completely closed; when the plug is pulled out of the through-flow opening 18, the bypass flow path is completely open.
The rest of this embodiment is the same as embodiment 1, and is not described again.
The above description is only a preferred embodiment of the present invention, and therefore should not be taken as limiting the scope of the invention, which is defined by the appended claims and their equivalents.
