Description

Technical Field

[0001] This utility model relates to the field of one-way valve technology, and in particular to a multi-channel one-way valve. Background Technology

[0002] A check valve uses fluid to push the valve core, overcoming the spring force of the valve core and causing it to leave the valve seat. The fluid then flows through the gap between the valve body and the valve core, achieving the desired flow. The fluid inflow and outflow directions are fixed, typically in a straight line. However, hydraulic systems require different fluid directions for different control requirements. Therefore, a valve block is usually designed to change the flow direction, which increases product cost. Furthermore, ordinary check valves generally only have on / off functions and lack flow regulation capabilities, requiring the installation of a regulating valve to achieve flow regulation. This application addresses these shortcomings. Utility Model Content

[0003] The purpose of this invention is to provide a multi-channel check valve, which solves the problem that current check valves generally only have one fluid flow direction, making it difficult to adapt to the needs of hydraulic systems.

[0004] To address the aforementioned problems, this utility model provides a multi-channel check valve, comprising a base, a valve seat, a valve core, and an elastic component. The base is provided with an inlet, a channel, and an outlet. The valve seat, valve core, and elastic component constitute a check valve body assembly. The valve seat, valve core, and elastic component are disposed within the channel. Several sets of outlets are provided, each oriented in a different direction. One or more outlets can be selected for use according to the design requirements of the hydraulic system for flow direction. If only one outlet is used, the other outlets can also be used as backflushing ports.

[0005] According to one embodiment of the present invention, a ball valve is provided in the base, the ball valve is connected to a ball valve stem, and the ball valve stem extends to the outside of the base. By rotating the ball valve stem, the water flow rate of the channel can be adjusted.

[0006] According to one embodiment of the present invention, the ball valve is located between the inlet and the valve core.

[0007] According to one embodiment of the present invention, the channel is connected to a bypass port, and when the ball valve is closed, the liquid flows out from the bypass port.

[0008] According to one embodiment of the present invention, the base is provided with a plurality of one-way valve mounting holes, which are distributed on the surface of the base having an outlet. The one-way valve mounting holes are used for mounting one-way valves in various directions.

[0009] According to one embodiment of the present invention, the base adopts a hexahedral structure, with an inlet on one side and outlets on the other sides, i.e., five outlets are provided.

[0010] According to one embodiment of the present invention, the one-way valve mounting holes are provided on all end faces of the base, which facilitates the adjustment of the one-way valve installation method according to requirements and installation position.

[0011] According to one embodiment of the present invention, both the inlet and outlet are provided with sealing ring mounting grooves for installing sealing rings to achieve sealing.

[0012] According to one embodiment of the present invention, at least two sets of ball valve sealing gaskets that contact the ball valve are provided in the channel.

[0013] According to one embodiment of the present invention, the elastic component is a spring, the valve seat is provided with a tapered hole, and the valve core is provided with a tapered surface.

[0014] The beneficial effect of this utility model is that by setting several outlets with different orientations and positions, one or more outlets can be selected for use according to the design requirements of the hydraulic system for the flow direction. Unused outlets can be plugged, and outlets with plugs cannot flow out. This can replace part of the function of the valve block and achieve the purpose of reducing costs.

[0015] By setting up ball valves and bypass ports, and controlling the state of the ball valves, the flow rate of water flowing through the water flow channel can be adjusted to achieve the effect of flow regulation. Attached Figure Description

[0021] The following description is only intended to disclose the present invention so that those skilled in the art can implement it. The embodiments in the following description are merely examples, and those skilled in the art will conceive of other obvious modifications. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other solutions that do not depart from the spirit and scope of the present invention.

[0022] Example 1:

[0023] A multi-channel check valve, such as Figure 1 It includes a base 8, a valve seat 3, a valve core 4, and an elastic component 5.

[0024] The base 8 is provided with an inlet 1, a channel 12 and an outlet 2. The elastic component 5 is a spring. The valve seat 3 is provided with a tapered hole and the valve core 4 is provided with a tapered surface. The valve seat 3 is installed in the channel 12 and the valve core 4 is installed coaxially below the valve seat 3. The tapered surface of the valve core 4 can cooperate with the tapered surface of the tapered hole of the valve seat 3 to achieve a seal. The spring is installed below the valve core 4. The valve seat 3, the valve core 4 and the elastic component 5 constitute a one-way valve body assembly.

[0025] The outlet 2 is provided in several groups, each facing a different direction. One or more outlets can be selected for use according to the design requirements of the hydraulic system for the flow direction. Unused outlets are fitted with plugs, and fluid cannot flow out of the outlets with plugs. If only one outlet is used, the other outlets can also be used as backwash ports.

[0026] Optionally, a plug can be installed on the unused outlet 2. The outlet with the plug cannot flow fluid, which can replace part of the function of the valve block and reduce costs.

[0027] Both the inlet 1 and the outlet 2 are provided with sealing ring mounting grooves 6 for installing sealing rings to achieve sealing.

[0028] The base 8 is provided with a plurality of one-way valve mounting holes 13, which are distributed on the surface of the base 8 having an outlet 2. The one-way valve mounting holes 13 are used for mounting one-way valves in various directions.

[0029] Example 2:

[0030] Based on Embodiment 1, the base 8 adopts a hexahedral structure, with an inlet 1 on one side and outlets 2 on the other sides, i.e., five outlets 2 are provided. One-way valve mounting holes 13 are provided on all end faces of the base 8, which facilitates the adjustment of the one-way valve installation method according to requirements and installation position.

[0031] Example 3:

[0032] Based on Example 1 or 2, this example adds a flow rate adjustment function.

[0033] Specifically, such as Figure 4 A ball valve 7 is installed in the base 8 between the inlet 1 and the valve core 4. The ball valve 7 is connected to the ball valve stem 11, which extends to the outside of the base 8. By rotating the ball valve stem 11, the water flow rate of the channel 12 can be adjusted. Ball valve sealing gaskets 9 are provided on both sides of the ball valve 7. A bypass port 10 is provided on the side of the channel 12 near the inlet 1. When the ball valve 7 is closed, the liquid flows out from the bypass port 10.

[0034] The ball valve 7 has a water flow channel in the middle. When the water flow channel is perpendicular to the plane of the inlet 1, it enables water flow. When the water flow channel is parallel to the plane of the inlet 1, it enables water flow to be closed. Water enters from the inlet 1 and flows out through the bypass port 10.

[0035] When the water flow channel and inlet 1 are in a non-flowing and non-closed intermediate state, the flow rate of water flowing through the water flow channel can be adjusted by rotating the ball valve stem 11. The ball valve body generates resistance A. At the same time, due to the change in water flow, the water pressure acting on the valve core 4 will also change, and the opening distance between the valve seat 3 and the valve core 4 will change. The valve core 4 generates resistance B, which plays a second role in regulating the water flow. At this time, the bypass port 10 can be closed by the shut-off function of the external pipeline. Under the action of resistance A+B, the water flows into inlet 1, which plays a role in regulating the water flow.

[0036] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functional and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations and modifications.
