Description

Technical Field

[0001] The utility model belongs to the technical field of water supply equipment, and more specifically, it particularly relates to a water supply equipment with adjustable flow rate. Background Art

[0002] Water supply refers to the provision of water resources through public facilities, commercial organizations, community efforts or individuals. The transportation of water is usually through pumps and pipelines, and the regulation of water supply flow rate is controlled by valves. By adjusting the opening degree of the valves, the water supply usage requirements of different flow rates can be achieved.

[0003] For the valves of existing water supply equipment used to regulate water flow rate, they do not have a locking structure, and their valve stems can rotate freely. Therefore, after the water flow rate is regulated through the valve stem, the valve stem is very likely to rotate accidentally due to external factors such as accidental collision, thus changing the set water flow rate parameters, with poor stability and low practicality. Summary of the Utility Model

[0004] The embodiment of the present disclosure relates to a water supply equipment with adjustable flow rate, which has a control component. The control component can adjust the water supply flow rate of the opening and closing component, so as to meet the water supply usage requirements of different flow rates. At the same time, the control component has two usage modes. One is the self-locking mode. In this mode, the control component is in a locked state when in the reset state, thus avoiding accidental change of the set water flow rate parameters due to external factors such as accidental collision. It is stable in use, and the water flow rate can also be regulated in the self-locking mode. The other is the free mode. In this mode, the operating rod can rotate freely, which is no different from the usage method of traditional valves. The two usage modes can be switched and selected as needed, and can meet the usage requirements in different environments, with extremely strong flexibility, adaptability, stability and practicality.

[0005] In the first aspect of the present disclosure, a water supply equipment with adjustable flow rate is provided, including an opening and closing component and a control component. The opening and closing component includes a water supply pipeline, an opening and closing valve core and a control valve stem. One end of the water supply pipeline is connected to the water supply equipment, and the opening and closing valve core is rotatably connected inside the water supply pipeline. The control valve stem is fixedly installed on the top of the opening and closing valve core. The control component includes a mounting seat, an operating rod and a switching rod. The mounting seat is fixedly installed on the top of the water supply pipeline, and the operating rod is inserted inside the mounting seat. The switching rod is inserted inside the operating rod.

[0006] In at least some embodiments, the operating rod, the switching rod and the control valve stem are on the same rotation axis.

[0007] In at least some embodiments, a synchronizing rod is provided at the bottom of the operating rod, and the cross-sectional shape of the rod body of the synchronizing rod is a regular polygon. A synchronizing groove is provided at the top of the control valve stem, and the synchronizing rod is inserted inside the synchronizing groove.

[0008] In at least some embodiments, a locking top spring is provided outside the operating rod, and both ends of the locking top spring respectively abut against the middle of the operating rod and the inside of the mounting seat.

[0009] In at least some embodiments, a locking gear is provided in the middle of the rod body of the operating rod, and a locking tooth groove is provided inside the mounting seat. Under the action of the locking top spring, when the operating rod is not pulled by an external force, the locking gear is inserted into the inside of the locking tooth groove.

[0010] In at least some embodiments, the outer rod body of the switching rod is provided with threads, and the switching rod is screwed inside the operating rod through the rod body threads, and the bottom of the switching rod can penetrate the inside of the operating rod.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] The control assembly can adjust the water supply flow rate of the opening and closing assembly, so as to adapt to the water supply use requirements of different flow rates. At the same time, the control assembly has two use modes. One is the self-locking mode. In this mode, the control assembly is in a locked state in the reset state, so as to avoid accidental changes in the set water flow rate parameters caused by external factors such as accidental touching and bumping. The use is stable, and the water flow rate can also be adjusted in the self-locking mode. The other is the free mode. In this mode, the operating rod can rotate freely, which is no different from the use method of a traditional valve. The two use modes can be switched and selected according to needs, which can adapt to the use requirements in different environments and improve the flexibility, adaptability, stability and practicability of the device.

[0023] The following further describes the implementation mode of the present utility model in detail with reference to the drawings and embodiments

[0024] As shown in Figure 1 to Figure 7 shown

[0025] Embodiment 1: The present utility model provides a water supply device with adjustable flow rate, including an opening and closing assembly 1 and a control assembly 2. The opening and closing assembly 1 includes a water supply pipeline 101, an opening and closing valve core 102 and a control valve rod 103. One end of the water supply pipeline 101 is connected to the water supply device, and the opening and closing valve core 102 is rotatably connected inside the water supply pipeline 101. The control valve rod 103 is fixedly installed on the top of the opening and closing valve core 102. The control assembly 2 includes a mounting seat 201, an operating rod 202 and a switching rod 203. The mounting seat 201 is fixedly installed on the top of the water supply pipeline 101, and the operating rod 202 is inserted inside the mounting seat 201, and the switching rod 203 is inserted inside the operating rod 202

[0026] In the embodiment of the present disclosure, the outer surface of the rod body of the switching rod 203 is provided with threads, and the switching rod 203 is screwed inside the operating rod 202 through the rod body threads. The bottom of the switching rod 203 can penetrate the inside of the operating rod 202. During use, by changing the exposed length of the switching rod 203 at the bottom of the operating rod 202, the switching use between the two use modes of the control assembly 2 can be realized. The switching is fast and convenient. When the switching rod 203 is rotated alone, the switching rod 203 can move up and down inside the operating rod 202 through the rod body threads to change the use position. Thus, when the switching rod 203 is completely hidden inside the operating rod 202, the control assembly 2 is in the self-locking mode. At this time, the control assembly 2 is in the locked state when in the reset state, thereby avoiding accidental change of the set water flow rate parameters due to external factors such as accidental touch and collision. The use is stable. When the switching rod 203 extends a certain length from the bottom of the operating rod 202, at this time the control assembly 2 is in the free mode. At this time, the operating rod 202 can rotate freely, which is no different from the use method of traditional valves, and the use is flexible

[0027] In the embodiment of the present disclosure, the operating rod 202, the switching rod 203 and the control valve rod 103 are on the same rotation axis. During use, when the control assembly 2 is in the self-locking mode, a locking top spring 2022 is provided outside the operating rod 202, and both ends of the locking top spring 2022 abut against the middle of the operating rod 202 and the inside of the mounting seat 201 respectively. Under the action of the locking top spring 2022, the locking gear 2023 is inserted into the locking tooth groove 2011. At this time, the operating rod 202 is locked and cannot rotate self. A synchronizing rod 2021 is provided at the bottom of the operating rod 202, and the cross-sectional shape of the rod body of the synchronizing rod 2021 is a regular polygon. A synchronizing groove 1031 is provided at the top of the control valve rod 103, and the synchronizing rod 2021 is inserted into the synchronizing groove 1031. The synchronizing rod 2021 can lock the control valve rod 103 synchronously through the synchronizing groove 1031, so that the control valve rod 103 also cannot rotate self, and can stably maintain the current use angle and state of the opening and closing valve core 102, avoiding accidental change of the set water flow parameters of the control assembly 2 due to external factors such as accidental collision. When it is necessary to adjust the water flow of the opening and closing assembly 1, only need to lift and rotate the operating rod 202. When the operating rod 202 is lifted, the locking top spring 2022 will be compressed, and the locking gear 2023 will be disengaged from the inside of the locking tooth groove 2011. Thereafter, the operating rod 202 can rotate freely. When the operating rod 202 rotates thereafter, the synchronizing rod 2021 can drive the control valve rod 103 to rotate synchronously through the synchronizing groove 1031 to change the use angle and state of the opening and closing valve core 102, thus realizing the function of regulating the water flow of the opening and closing assembly 1. The regulation is convenient. After the regulation is completed and the operating rod 202 is released, the operating rod 202 can automatically reset to the locked state under the action of the locking top spring 2022, and the use is stable.

[0028] In the embodiment of the present disclosure, a locking gear 2023 is provided in the middle of the rod body of the operating rod 202, and a locking tooth groove 2011 is provided inside the mounting seat 201. Under the action of the locking top spring 2022, when the operating rod 202 is not pulled by external force, the locking gear 2023 is inserted into the locking tooth groove 2011. During use, when the control assembly 2 is in the free mode, at this time, the switching rod 203 extends out of the bottom of the operating rod 202, so that the switching rod 203 will lift the operating rod 202, making the locking gear 2023 always in the state of disengaging from the inside of the locking tooth groove 2011, that is, the operating rod 202 is always in the unlocked state and can rotate freely. Thus, by directly rotating the operating rod 202, the regulation of the use angle and state of the opening and closing valve core 102 can be realized, and the use is convenient and the regulation is fast.

[0029] The specific usage and function of this embodiment:

[0030] In the present utility model, the usage mode of the on-demand regulation control component 2 is regulated as required. By changing the exposed length of the switching rod 203 at the bottom of the operating rod 202, the switching use between the two usage modes of the control component 2 can be realized. The switching is fast and convenient. When the switching rod 203 is rotated alone, the switching rod 203 can move up and down inside the operating rod 202 through the rod body thread to change the usage position. Thus, when the switching rod 203 is completely hidden inside the operating rod 202, the control component 2 is in the self-locking mode. At this time, the control component 2 is in the locked state when in the reset state, so as to avoid accidental change of the set water flow parameters of the control component 2 due to external factors such as accidental touch or collision. The use is stable. When the switching rod 203 extends a certain length from the bottom of the operating rod 202, at this time the control component 2 is in the free mode. At this time, the operating rod 202 can rotate freely, which is no different from the usage method of a traditional valve. When the control component 2 is in the self-locking mode, under the action of the locking top spring 2022, the locking gear 2023 is inserted into the internal of the locking tooth groove 2011. At this time, the operating rod 202 is locked and cannot rotate self. The synchronizing rod 2021 can lock the control valve rod 103 synchronously through the synchronizing groove 1031. Thus, the control valve rod 103 also cannot rotate self, and can stably maintain the current usage angle and state of the opening and closing valve core 102, avoiding accidental change of the set water flow parameters of the control component 2 due to external factors such as accidental touch or collision. When it is necessary to adjust the water flow of the opening and closing component 1, only need to lift and rotate the operating rod 202. When the operating rod 202 is lifted, the locking top spring 2022 will be compressed, and the locking gear 2023 will be disengaged from the internal of the locking tooth groove 2011. Thus, the operating rod 202 can rotate freely thereafter. When the operating rod 202 rotates thereafter, the synchronizing rod 2021 can drive the control valve rod 103 to rotate synchronously through the synchronizing groove 1031 to change the usage angle and state of the opening and closing valve core 102, thus realizing the function of regulating the water flow size of the opening and closing component 1. The regulation is convenient. After the regulation is completed and the operating rod 202 is released, the operating rod 202 can automatically reset to the locked state under the action of the locking top spring 2022. When the control component 2 is in the free mode, at this time the switching rod 203 extends from the bottom of the operating rod 202. Thus, the switching rod 203 will lift the operating rod 202, so that the locking gear 2023 is always in the state of being disengaged from the internal of the locking tooth groove 2011, that is, the operating rod 202 is always in the unlocked state and can rotate freely. Thus, the regulation of the usage angle and state of the opening and closing valve core 102 can be realized by directly rotating the operating rod 202.
