Description

Technical Field

[0001] The utility model belongs to the technical field of one-way valves, and in particular relates to a one-way valve for high-viscosity solvents. Background Art

[0002] A one-way valve is a valve that allows fluid to flow only along the inlet, but the medium at the outlet cannot flow back. It is commonly known as a one-way valve. A one-way valve is also called a check valve or a non-return valve. It is used in hydraulic systems to prevent oil from flowing in the opposite direction, or in pneumatic systems to prevent compressed air from flowing in the opposite direction. There are two types of one-way valves: straight-through and right-angle. Straight-through one-way valves are installed on the pipeline with threaded connections. Right-angle one-way valves are available in three forms: threaded connection, plate connection, and flange connection.

[0003] When the one-way valve is in use, when the fluid is passed in the positive direction, the fluid pushes the valve core to allow the fluid to pass through. Since the valve core is inside the valve and occupies the internal space of the valve, it will have a certain obstructive effect on the fluid when in use. In particular, when high-viscosity fluid passes through, the valve core obstructs the flow of the fluid and affects the flow rate of the high-viscosity fluid. Utility Model Content

[0004] The utility model aims to provide a high-viscosity solvent one-way valve, when the fluid pressure is high, the conical rubber pad of the sealing head is impact-deformed, so that the fluid flows out through the through hole, thereby increasing the flow rate of the fluid, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high-viscosity solvent one-way valve, comprising an outer shell and a core body, the outer shell comprising a shell, the interior of the shell being fixedly connected to a liquid inlet bucket, the core body being slidably connected to the interior of the shell, the exterior of the core body being sleeved with a spring, the two ends of the spring being respectively fixedly connected to one end of the core body and one end of the liquid inlet bucket, the core body comprising an openable and closable sealing head, the sealing head being arranged inside the liquid inlet bucket, one end of the sealing head being fixedly connected to a connecting rod, one end of the connecting rod being fixedly connected to a driving end head, and one end of the spring being fixedly connected to one end of the driving end head.

[0006] Furthermore, both ends of the shell are fixedly connected with end pipes.

[0007] Furthermore, the sealing head comprises a cone, and a side wall of the cone is provided with evenly distributed through holes.

[0008] Furthermore, a conical rubber pad is provided on the inner wall of the cone bucket, and one end of the conical rubber pad is fixedly connected to one end of the inner wall of the cone bucket.

[0009] Furthermore, one end of the connecting rod is fixedly connected to one end of the cone bucket.

[0010] Furthermore, the driving end head includes a disc, one end of which is fixedly connected to one end of a connecting rod, the side of the disc is fixedly connected to an extension plate equidistantly distributed around the axis of the disc, and one end of the extension plate is fixedly connected to an L-shaped plate.

[0011] Furthermore, the side wall of the L-shaped plate is slidably connected to the side wall of the shell, and one end of the L-shaped plate is fixedly connected to one end of the spring.

[0012] Compared with the prior art, the utility model has the following beneficial effects: the fluid flow pushes the sealing head to move, so that the gap between the sealing head and the liquid inlet bucket is opened, thereby allowing the fluid to pass through; when the pressure of the fluid is relatively large, the conical rubber pad of the sealing head is deformed by the impact, so that the fluid flows out through the through hole, reducing the resistance to the fluid and increasing the flow rate of the fluid.

[0018] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0019] like Figure 1-3As shown, a high-viscosity solvent one-way valve includes an outer shell 1 and a core body 2, the outer shell 1 includes a shell body 11, the interior of the shell body 11 is fixedly connected to a liquid inlet hopper 13, the core body 2 is slidably connected to the interior of the shell body 11, a spring 3 is sleeved on the exterior of the core body 2, the two ends of the spring 3 are respectively fixedly connected to one end of the core body 2 and one end of the liquid inlet hopper 13, the core body 2 includes an openable and closable sealing head 21, the sealing head 21 is arranged in the interior of the liquid inlet hopper 13, one end of the sealing head 21 is fixedly connected to a connecting rod 22, one end of the connecting rod 22 is fixedly connected to a driving end 23, and one end of the spring 3 is fixedly connected to one end of the driving end 23.

[0020] According to the above structure, when in use, after the fluid enters the interior of the shell 11 through one of the end tubes 12, it first impacts and pushes the driving end head 23. After the driving end head 23 is pushed, it squeezes the spring 3 and moves together with the transmission sealing head 21 through the connecting rod 22. When the fluid flows, it will also impact the sealing head 21, so that the gap between the sealing head 21 and the liquid inlet bucket 13 is opened, so that the fluid can pass through. When the pressure of the fluid is relatively large, the sealing head 21 itself will also open to further allow the fluid to pass through, thereby avoiding obstruction of the fluid and affecting the flow rate of the fluid.

[0021] like Figure 1 As shown, both ends of the shell 11 are fixedly connected with end pipes 12.

[0022] According to the above structure, when in use, the end tube 12 close to the driving end 23 is used as the liquid inlet end, and the other end tube 12 is used as the liquid outlet end.

[0023] like Figure 2 and 3 As shown, the driving end head 23 includes a disc 231, one end of which is fixedly connected to one end of the connecting rod 22, and the side of the disc 231 is fixedly connected to an extension plate 232 equidistantly distributed around the axis of the disc 231, and one end of the extension plate 232 is fixedly connected to an L-shaped plate 233, and the side wall of the L-shaped plate 233 is slidably connected to the side wall of the shell 11, and one end of the L-shaped plate 233 is fixedly connected to one end of the spring 3.

[0024] According to the above structure, when the fluid flows into the shell 11, it impacts the disc 231, thereby pushing the entire driving end head 23 to move along the direction of fluid flow. The L-shaped plate 233 squeezes the spring 3 and is pushed through the transmission sealing head 21 of the connecting rod 22.

[0025] like Figure 3 As shown, the sealing head 21 includes a cone bucket 211, the side wall of which is provided with evenly distributed through holes 212, the inner wall of the cone bucket 211 is provided with a cone rubber pad 213, one end of the cone rubber pad 213 is fixedly connected to one end of the inner wall of the cone bucket 211, and one end of the connecting rod 22 is fixedly connected to one end of the cone bucket 211.

[0026] According to the above structure, the connecting rod 22 pushes the cone bucket 211 to move along the direction of the fluid, so that the gap between the cone bucket 211 and the liquid inlet bucket 13 is opened, and the fluid can flow through the gap. When the flow of the fluid is blocked, the fluid can impact the conical rubber pad 213 through the through hole 212 to deform the conical rubber pad 213. The fluid flows through the through hole 212, thereby increasing the flow rate of the fluid and reducing the obstruction of the core body 2 to the fluid. When the fluid flows in the opposite direction, the spring 3 pushes the core body 2 to reset the gap between the cone bucket 211 and the liquid inlet bucket 13 to be closed, and the conical rubber pad 213 is pressed against the inner wall of the cone bucket 211 to prevent the fluid from passing.

[0027] The working principle of the utility model is as follows: when in use, the end tube 12 close to the driving end head 23 is used as the liquid inlet end, and the other end tube 12 is used as the liquid outlet end. When the fluid flows into the shell 11, it impacts the disc 231, thereby pushing the entire driving end head 23 to move in the direction of the fluid flow, and the L-shaped plate 233 squeezes the spring 3, and the transmission sealing head 21 through the connecting rod 22 is pushed, and the connecting rod 22 pushes the cone bucket 211 to move in the direction of the fluid, so that the gap between the cone bucket 211 and the liquid inlet bucket 13 is opened, and the fluid can flow through the gap. When the fluid flow is blocked, the fluid can pass through the through hole 212 to impact the conical rubber pad 213 to deform the conical rubber pad 213, and the fluid flows through the through hole 212, thereby increasing the flow rate of the fluid and reducing the obstruction of the core 2 to the fluid. When the fluid flows in the opposite direction, the spring 3 pushes the core 2 to reset the gap between the cone bucket 211 and the liquid inlet bucket 13 to be closed, and the conical rubber pad 213 is tightly attached to the inner wall of the cone bucket 211 to prevent the fluid from passing.

[0028] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
