Description

Technical Field

[0001] The utility model relates to the technical field of flow controllers, in particular to a flow controller with a rubber throttle ring. Background Art

[0002] The flow controller is an intuitive and simple flow control device. The automatic flow control valve used in the pipe network can directly set the flow according to the design. The valve can automatically eliminate the flow deviation caused by the residual pressure head and pressure fluctuation of the pipeline under the action of water. No matter how the system pressure changes, the set flow is kept unchanged. These functions of the valve enable the pipe network flow regulation to be completed at one time, turning the network adjustment work into a simple flow distribution, and effectively solving the hydraulic imbalance of the pipe network. It is mainly used in water systems such as centralized heating (cooling), so that the pipe network flow is distributed on demand, the hydraulic imbalance of the water system is eliminated, and the problem of uneven hot and cold can be solved, which can save energy and electricity by 15%-20%. The flow controller is used in the cooling water system of the shield machine to control the cooling water flow of important components such as the main drive motor, the main drive reducer, the main hydraulic station water-cooled motor, and the frequency conversion cabinet. The shield machine will generate a lot of heat during use, so the cooling effect will directly affect the service life of the whole machine.

[0003] During the operation of the shield machine cooling water system, the flow of water in the pipeline will fluctuate, which will affect the heat dissipation effect. In order to effectively control the cooling water flow and stabilize the heat dissipation effect, an adjustable flow controller is generally equipped. Traditional flow controllers are divided into two types: adjustable flow and non-adjustable flow. The non-adjustable flow controller cannot adjust the flow with the system pressure. The adjustable flow controller must be opened manually or by electric flow controller. The control is more complicated and is not suitable for this working condition, so it needs to be improved. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the shortcomings of the prior art and provide a flow controller with a rubber throttle ring to solve the problem in the prior art that during the operation of the shield machine cooling water system, the flow of water in the pipeline will fluctuate and affect the heat dissipation effect. In order to effectively control the cooling water flow and stabilize the heat dissipation effect, an adjustable flow controller is generally equipped. Traditional flow controllers are divided into two types: adjustable flow and non-adjustable flow. The non-adjustable flow controller cannot adjust the flow with the system pressure, and the adjustable flow controller must be controlled by manual or electric flow controller port opening, which is more complicated and not suitable for this working condition.

[0005] In view of this, the utility model provides a flow controller with a rubber throttle ring, including a first cylinder and a second cylinder, wherein a first mounting groove and a second mounting groove are respectively provided at one end of the first cylinder and the second cylinder, a rubber throttle ring is arranged between the first cylinder and the second cylinder, and a connecting assembly is arranged between the first cylinder and the second cylinder.

[0006] Optionally, the rubber throttle ring is fixedly installed between the first installation groove and the second installation groove.

[0007] Optionally, a through hole with a diameter of 6 mm is opened at the axial center of one end of the first cylinder.

[0008] Optionally, a through hole with a diameter of 19.5 mm is opened at the axial center of one end of the second cylinder.

[0009] Optionally, the connection assembly comprises a clamping ring, a connecting sleeve (7) and a sealing ring, the clamping ring being fixedly connected to the outer wall of one end of the first cylinder, one end of the connecting sleeve being rotatably connected to the outside of the clamping ring, and the sealing ring being fixedly mounted at one end of the first cylinder.

[0010] Optionally, the inner side of one end of the connecting sleeve is threadedly connected to one end of the second cylinder.

[0011] Optionally, the outer wall of the sealing ring is disposed against an end surface of the second cylinder.

[0012] It can be seen from the above technical solutions that the embodiments of the utility model have the following advantages:

[0013] 1. The utility model discloses a flow controller with a rubber throttle ring, which is provided with a first cylinder, a second cylinder and a rubber throttle ring. Specifically, after the flow controller is installed, cooling water flows from the first cylinder to the second cylinder. When the cooling water pressure increases, the flow rate and flow rate increase. The rubber throttle ring in the flow controller is deformed by the water pressure, the area of ​​the middle flow port becomes smaller, and the regulated flow rate decreases. Similarly, when the cooling water pressure decreases, the flow rate and flow rate decrease. The rubber throttle ring in the flow controller is reduced by the water pressure, the deformation is restored, the area of ​​the middle flow port increases, and the regulated flow rate increases. The flow controller can achieve stable regulated flow rate and ensure stable heat dissipation effect.

[0014] 2. The utility model provides a flow controller with a rubber throttle ring, which is threadedly connected by a connecting assembly, specifically, a connecting sleeve and a second cylinder. When the rubber throttle ring is corroded and aged after long-term use, the connecting sleeve is unscrewed from the second cylinder, the first cylinder and the second cylinder are separated, and the rubber throttle ring can be replaced, thereby facilitating maintenance of the flow controller.

[0015] These features and advantages of the present invention will be disclosed in detail in the following specific implementation manners and drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following is an explanation and description of the technical scheme of the embodiment of the utility model in conjunction with the drawings of the embodiment of the utility model, but the following embodiment is only a preferred embodiment of the utility model, not all. Based on the embodiment in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the utility model.

[0024] A flow controller with a rubber throttle ring according to an embodiment of the utility model will be described in detail below in conjunction with the accompanying drawings.

[0025] Example 1

[0026] For easier understanding, see Figures 1 to 5 The utility model provides an embodiment of a flow controller with a rubber throttle ring, comprising a first cylinder 1 and a second cylinder 2, wherein a first mounting groove 3 and a second mounting groove 4 are respectively provided at one end of the first cylinder 1 and the second cylinder 2, a rubber throttle ring 5 is provided between the first cylinder 1 and the second cylinder 2, a connecting component is provided between the first cylinder 1 and the second cylinder 2, the rubber throttle ring 5 is fixedly installed between the first mounting groove 3 and the second mounting groove 4, a through hole with a diameter of 6 mm is provided at the axis center of one end of the first cylinder 1, and a through hole with a diameter of 19.5 mm is provided at the axis center of one end of the second cylinder 2.

[0027] It should be noted that, by installing the rubber throttle ring 5 between the first installation groove 3 and the second installation groove 4 opened in the first cylinder 1 and the second cylinder 2, after the flow controller is installed, the cooling water flows from the first cylinder 1 to the second cylinder 2, when the cooling water pressure increases, the flow rate and flow rate increase, the rubber throttle ring 5 in the flow controller is deformed by the water pressure, the area of ​​the middle flow port becomes smaller, and the regulated flow rate decreases. Similarly, when the cooling water pressure decreases, the flow rate and flow rate decreases, the rubber throttle ring 5 in the flow controller is reduced by the water pressure, the deformation is restored, the area of ​​the middle flow port increases, and the regulated flow rate increases. The flow controller can achieve the stability of the regulated flow rate, thereby ensuring the stability of the heat dissipation effect.

[0028] Example 2

[0029] In some embodiments, Figure 1 , Figure 2 , Figure 3 As shown, the connecting assembly includes a clamping ring 6, a connecting sleeve 7 and a sealing ring 8, the clamping ring 6 is fixedly connected to the outer wall of one end of the first cylinder 1, one end of the connecting sleeve 7 is rotatably connected to the outside of the clamping ring 6, the sealing ring 8 is fixedly installed at one end of the first cylinder 1, the inner side of one end of the connecting sleeve 7 is threadedly connected to one end of the second cylinder 2, and the outer wall of the sealing ring 8 is against the surface of one end of the second cylinder 2.

[0030] It should be noted that, by providing a connecting sleeve 7 for threaded connection with the second cylinder 2, the separated first cylinder 1 and second cylinder 2 can be connected into a whole. When the rubber throttle ring 5 is corroded and aged after long-term use, the connecting sleeve 7 is unscrewed from the second cylinder 2, the first cylinder 1 and the second cylinder 2 are separated, and the rubber throttle ring 5 can be replaced, thereby facilitating the maintenance of the flow controller. The sealing ring 8 is provided to ensure the sealing when the first cylinder 1 and the second cylinder 2 are connected.

[0031] Working principle: After the flow controller is installed, the cooling water flows from the first cylinder 1 to the second cylinder 2. When the cooling water pressure increases, the flow rate and flow rate increase. The rubber throttle ring 5 in the flow controller is deformed by the water pressure, the area of ​​the middle flow port becomes smaller, and the regulated flow rate decreases. Similarly, when the cooling water pressure decreases, the flow rate and flow rate decrease. The rubber throttle ring 5 in the flow controller is affected by the water pressure reduction, the deformation is restored, the area of ​​the middle flow port increases, and the regulated flow rate increases. The flow controller can achieve stable regulated flow rate and ensure the stability of the heat dissipation effect. Then, when the rubber throttle ring 5 is corroded and aged after long-term use, the connecting sleeve 7 is unscrewed from the second cylinder 2, the first cylinder 1 and the second cylinder 2 are separated, and the rubber throttle ring 5 can be replaced, thereby facilitating the maintenance of the flow controller.
