Description

Technical Field

[0001] This utility model relates to the field of regulating valve technology, specifically to an anti-collision valve structure and a water supply regulating valve using the same. Background Technology

[0002] Three-way regulating valves are mainly used in pipelines for cutting off, distributing, and changing the flow direction of media, and are a widely adopted new type of valve. Patent application CN202120528068.2 discloses a flow-adjustable three-way regulating valve, including an inlet, a first outlet, and a second outlet. Its valve body mechanism includes a valve stem mechanism, and flow dampers are installed at the inlets of the first and second valve bodies to reduce the impact of the flow on the valve body and increase its service life. Throttling components are installed inside the first and second outlets to control the flow rate, improving the flexibility of valve use. However, both throttling components are fixedly installed, making it impossible to adjust the flow rate at only one outlet independently. Furthermore, the valve stem mechanism synchronously drives the movement of both valve bodies; when the flow rate at one outlet is adjusted, water will inevitably flow through the other outlet, making it impossible to control the flow rate while ensuring only one outlet is connected. In addition, its valve stem moves up and down, occupying a large space and is prone to loosening after accidental impacts. Utility Model Content

[0003] To address the technical problems in the background art, such as the inability of three-way regulating valves to regulate the flow of a single passage and the ease with which valves can loosen after accidental impact, this utility model provides an anti-collision valve structure and a water supply regulating valve using the same.

[0004] The technical solution of this utility model is as follows:

[0005] An anti-collision valve structure includes a valve body and an adjusting component capable of controlling the rotation of the valve body. The adjusting component includes a main shaft, one end of which is connected to the valve body, and the other end has a groove on its outer side. The adjusting component also includes a main cylinder rotatably sleeved on the outer ring of the main shaft away from the valve body, and the main cylinder has a through hole. The adjusting component also includes a rod, one end of which passes through the through hole and is inserted into the groove. When the rod is inserted into the groove, the main cylinder and the main shaft can rotate synchronously. That is, by rotating the main cylinder, the main shaft is driven to rotate, thereby realizing the rotation adjustment of the valve body. After the valve is adjusted, the rod is pulled out. At this time, the main cylinder and the main shaft are rotatably connected. When the valve is subjected to an accidental impact, the main cylinder will rotate around the main shaft, while the main shaft will not be affected by the impact, preventing the valve from opening accidentally and ensuring the safety of the valve.

[0006] Specifically, a buckle is provided at the position of the through hole on the side wall of the main body cylinder; the non-insertion end of the insertion rod is provided with a locking block that can be engaged with the buckle by rotation. After inserting one end of the insertion rod into the recess, rotating the insertion rod causes the locking block to engage with the locking block, thereby limiting the position of the insertion rod.

[0007] To facilitate easy access to the insertion rod, a storage slot is provided at the end of the main shaft away from the valve body to store the insertion rod, so that the operator does not need to carry the insertion rod with them.

[0008] Furthermore, to prevent the insertion rod from being lost and to reduce dust falling between the main body cylinder and the main body shaft, an openable cover plate is provided at the end of the main body cylinder away from the valve body. Covering the cover plate can cover and hide the insertion rod in the storage slot.

[0009] Preferably, the locking block has a handle on the side opposite to the insertion rod, which facilitates the picking up and rotating of the insertion rod.

[0010] In a preferred embodiment, the outer ring of the main body cylinder is also connected to an annular turntable, and the turntable is provided with several hand holes to facilitate rotating the main body cylinder when adjusting the valve. The turntable is annular, and both the outer and inner rings are smoothly arranged without sharp corners, so that no injury may occur if someone accidentally collides with it.

[0011] This utility model also provides a water supply regulating valve, including an inlet pipe, a first outlet pipe, a second outlet pipe, and a diverter valve rotatably disposed between the three. A throttling valve is rotatably installed inside both the first and second outlet pipes, and both the diverter valve and the throttling valve are equipped with adjusting components. The diverter valve controls the water flow direction in the inlet pipe, and the throttling valves individually installed on the first and second outlet pipes can control the flow rate of the internal water. Furthermore, the adjusting components prevent the diverter valve and the throttling valve from loosening or accidentally opening due to accidental impact, ensuring the overall safety of the water supply regulating valve.

[0012] Regarding the diversion valve, the diversion valve includes a spherical first valve body, which has a T-shaped channel. By rotating the first valve body, the water in the inlet pipe can be controlled to flow out through the first outlet pipe and / or the second outlet pipe, or the inlet pipe can be directly closed to cut off the water source. It is highly flexible and easy to adjust.

[0013] The throttle valve includes a spherical second valve body, inside which are a first passage and a second passage that are perpendicular to each other. The sidewalls of the second valve body corresponding to both ends of the first passage are open, and several flow-limiting orifices are provided on the sidewalls corresponding to both ends of the second passage. When water flows out through the first passage, its flow rate is relatively large. When a smaller flow rate is required, the diverter valve is rotated, and the water flow channel changes from the first passage to the second passage, flowing out through the flow-limiting orifices.

[0014] In a preferred embodiment, a sealing ring is also provided between the main shaft and the first and second water outlet pipes to improve the sealing between the adjusting component and the first and second water outlet pipes and prevent leakage.

[0015] Through the above design, the beneficial effects of this utility model's anti-collision valve structure and its application in a water supply regulating valve are as follows:

[0016] (1) By setting the diversion valve, the water flow in the inlet pipe can be controlled to flow out through the first outlet pipe and / or the second outlet pipe, or the inlet pipe can be directly closed to cut off the water source. It is highly flexible, easy to adjust, and suitable for various working conditions.

[0017] (2) Throttling valves are independently installed on the first and second water outlet pipes, which can control the flow rate of the internal water flow respectively.

[0018] (3) Both the diversion valve and the throttle valve are equipped with adjustment components. When the diversion valve and the throttle valve are subjected to an accidental impact, the main body cylinder will rotate around the main body shaft, while the main body shaft will not be affected by the impact, thus preventing the diversion valve and the throttle valve from opening accidentally and ensuring the overall safety of the water supply regulating valve.

[0029] Exemplary embodiments of this disclosure will now be described in more detail with reference to the accompanying drawings.

[0030] Example

[0031] Combination Figure 1 This embodiment first provides an anti-collision valve structure, including a valve body 1 and an adjusting member 2 that can control the rotation of the valve body 1; the adjusting member 2 includes a drive shaft 21, the drive shaft 21 includes a main shaft 211, one end of which is connected to the valve body 1, and the other end has a groove 212 on its outer side.

[0032] In this embodiment, the adjusting member 2 further includes a rotating cylinder 22, which includes a body cylinder 221 rotatably sleeved on the outer ring of the body shaft 211 away from the valve body 1.

[0033] For example, a rolling bearing is provided between the main body cylinder 221 and the main body shaft 211 to ensure the normal working position and rotational accuracy between the main body cylinder 221 and the main body shaft 211. The rolling bearing is convenient to use and maintain, reliable in operation, has good starting performance, and has a high load-bearing capacity at medium speeds.

[0034] As a preferred implementation method, combined with Figure 4 The outer ring of the main body cylinder 221 is also connected to an annular turntable 25, and the turntable 25 is provided with several hand holes to facilitate the rotation of the main body cylinder 221 when adjusting the valve. The turntable 25 is annular, and both the outer and inner rings are smoothly set without sharp corners, so that no one may be injured in case of accidental collision.

[0035] In this embodiment, combined with Figure 2 The main body cylinder 221 has a through hole 222, and a buckle 223 is provided on the side wall of the main body cylinder 221 at the position corresponding to the through hole 222. Two buckles 223 are provided along the diameter direction of the through hole 222 and are located on opposite sides of the through hole 222 respectively.

[0036] In this embodiment, combined with Figure 3The adjusting component 2 also includes a limiting pin 23, which comprises a rod 231, one end of which passes through the through hole 222 and is inserted into the recess 212. The non-insertion end of the rod 231 is provided with a locking block 232 that can be engaged with the latch 223 by rotation. After inserting one end of the rod 231 into the recess 212, rotating the rod 231 causes the locking block 232 to engage with the rod, thereby limiting the position of the rod 231. When the insert rod 231 is inserted into the sink 212, the main body cylinder 221 and the main body shaft 211 can rotate synchronously. That is, by rotating the main body cylinder 221, the main body shaft 211 is driven to rotate, thereby realizing the rotation adjustment of the valve body 1. After the valve is adjusted, the insert rod 231 is pulled out. At this time, the main body cylinder 221 and the main body shaft 211 are rotatably connected. When the valve is accidentally impacted, the main body cylinder 221 will rotate around the main body shaft 211, while the main body shaft 211 will not be affected by the impact, thus preventing the valve from being opened accidentally and ensuring the safety of the valve.

[0037] In specific implementation, the card block 232 has L-shaped protrusions symmetrically arranged along the center of the insertion rod 231 on both sides. By rotating, the two protrusions can be respectively engaged in the two buckles 223.

[0038] Preferably, the locking block 232 is provided with a handle 233 on the side opposite to the insertion rod 231, so as to facilitate the picking up and rotating of the insertion rod 231.

[0039] To facilitate easy access to the insertion rod 231, the end of the main shaft 211 away from the valve body 1 is provided with a storage groove 213 that can store the insertion rod 231, so that the operator does not need to carry the insertion rod 231 with him.

[0040] Furthermore, to prevent the insertion rod 231 from being lost and to reduce dust falling between the main body cylinder 221 and the main body shaft 211, an openable cover plate 24 is provided at the end of the main body cylinder 221 away from the valve body 1. The outer ring of the cover plate 24 is spirally connected to the inner ring of the main body cylinder 221, and a handle 233 is also provided on the upper side of the cover plate 24. Covering the cover plate 24 and tightening it can cover and hide the insertion rod 231 in the storage slot 213, and a pin is provided between the cover plate 24 and the main body cylinder 221 to prevent the cover plate 24 from being opened accidentally.

[0041] Combination Figure 5This utility model also provides a water supply regulating valve, including an inlet pipe, a first outlet pipe 3, a second outlet pipe 4, and a diversion valve 5 rotatably disposed between the three. A throttling valve 6 is rotatably installed inside both the first outlet pipe 3 and the second outlet pipe 4. An adjusting element 2 is provided on both the diversion valve 5 and the throttling valve 6. The diversion valve 5 controls the direction of water flow in the inlet pipe, and the throttling valves 6, individually installed on the first outlet pipe 3 and the second outlet pipe 4, can control the flow rate of the internal water. Simultaneously, the adjusting element 2 prevents the diversion valve 5 and the throttling valve 6 from loosening or accidentally opening due to accidental impact, ensuring the overall safety of the water supply regulating valve.

[0042] Regarding the diversion valve 5, the diversion valve 5 includes a spherical first valve body 51, which has a T-shaped channel. By rotating the first valve body 51, the water in the inlet pipe can be controlled to flow out through the first outlet pipe 3 and / or the second outlet pipe 4, or the inlet pipe can be directly closed to cut off the water source. It is highly flexible and easy to adjust.

[0043] Regarding the throttle valve 6, the throttle valve 6 includes a spherical second valve body 61, and the second valve body 61 has a first passage and a second passage that are perpendicular to each other; combined with Figure 7 The second valve body 61 has open side walls corresponding to both ends of the first passage, and several flow-limiting holes 62 are provided on the side walls corresponding to both ends of the second passage. When water flows out through the first passage, its flow rate is relatively large. When a smaller flow rate is required, the diversion valve 5 is rotated, and the water flow channel changes from the first passage to the second passage, flowing out through the flow-limiting holes 62.

[0044] Combination Figure 6 A sealing ring 7 is also provided between the main shaft 211 and the first water outlet pipe 3 and the second water outlet pipe 4 to improve the sealing between the adjusting component 2 and the first water outlet pipe 3 and the second water outlet pipe 4 and to prevent leakage.

[0045] Through the above design, the anti-collision valve structure of this utility model and the water supply regulating valve using it, through the setting of the diversion valve 5, can control the water flow in the inlet pipe to flow out through the first outlet pipe 3 and / or the second outlet pipe 4, or directly close the inlet pipe to cut off the water source. It has high flexibility, is easy to adjust, and is suitable for various working conditions. The first outlet pipe 3 and the second outlet pipe 4 are each independently equipped with a throttle valve 6, which can control the flow rate of the internal water flow respectively. Moreover, both the diversion valve 5 and the throttle valve 6 are equipped with an adjusting element 2. When the diversion valve 5 and the throttle valve 6 are accidentally impacted, the main body cylinder 221 will rotate around the main body shaft 211, while the main body shaft 211 will not be affected by the impact, preventing the diversion valve 5 and the throttle valve 6 from being opened accidentally, and ensuring the overall safety of the water supply regulating valve.
