Description

Technical Field

[0001] The utility model relates to the technical field of guide valves, in particular to a one-way valve capable of adjusting flow direction. Background Art

[0002] When lubricating oil is produced, the production equipment needs to use a one-way valve to control the outflow direction, and when oil is transferred, the flow direction needs to be controlled. The one-way valve can prevent the oil from flowing in the opposite direction, thereby protecting the system, such as avoiding damage to the pump due to a sudden increase in pressure.

[0003] With regard to the prior art, in addition to the ball valve being able to change the direction of oil flow, the ball valve is a two-way valve and cannot prevent the reverse flow of oil, but can only control opening and closing. If the existing one-way valve is to be used to change the direction of fluid flow, the one-way valve can only be removed, rotated 180°, and then installed again. This can achieve the effect of changing the direction of oil flow. However, this processing method is relatively cumbersome, and after disassembly, it is easy to cause oil to flow out of the pipeline and the one-way valve, causing waste.

[0004] Therefore, how to provide a one-way valve with adjustable flow direction to solve the problem that the existing one-way valve is inconvenient to change the flow direction is a technical problem that needs to be solved urgently by technical personnel in this field. Utility Model Content

[0005] To this end, the utility model provides a one-way valve with adjustable flow direction to solve the problem of oil waste caused by oil leakage when the existing one-way valve needs to be removed for switching.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] The utility model discloses a one-way valve capable of adjusting flow direction, comprising:

[0008] A connecting pipe, with pipes inserted at both ends, and blocks installed on the left and right sides of the inner wall of the connecting pipe;

[0017] A hole groove is provided in the annular plate body, a plurality of sliding blocks are arranged on the inner surface of the hole groove, and the valve assembly is drivingly connected in the hole groove.

[0018] In a possible implementation, the outer layer of the annular plate body is made of rubber material.

[0019] In a possible implementation, the valve assembly includes:

[0020] The cylinder is installed and drivingly connected in the installation plate;

[0021] A push plate is mounted on the rear surface of the mounting cylinder, a through hole is formed in the push plate, and one end of the reset assembly is disposed in the through hole;

[0022] A plurality of slide grooves are provided on the side wall of the installation cylinder;

[0023] A plurality of guide holes are provided on the side wall of the installation cylinder, and the guide holes are arranged between the two slide grooves.

[0024] In a possible implementation, the reset component includes:

[0025] An L-shaped connecting block, one end of which is mounted on the rear surface of the mounting plate, and a sleeve is mounted on the bottom of the other end;

[0026] A moving pipe is inserted into the front end of the sleeve, the valve assembly is connected to the outer surface of the moving pipe, the moving pipe is drivingly connected to the outside of the sleeve, and the moving pipe and the inside of the sleeve are hollow structures;

[0027] A return spring is installed in the hollow structure, the front end of the return spring is installed at the rear end of the moving tube front plate, and the rear end of the return spring is installed at the front end of the sleeve rear plate.

[0028] In a possible implementation, the rotating assembly includes a connecting rod and a knob, one end of the connecting rod passes through the connecting pipe and is inserted into the mounting plate, and the other end of the connecting rod is mounted with the knob.

[0029] In a possible implementation, a plurality of small holes are opened on the side wall of the connecting pipe, and the rotating assembly and the limiting bolts are inserted into the small holes.

[0030] The utility model allows only one-way flow of oil through the setting of the valve component, and the design of the reset component can ensure that the entire pipeline is in a closed state when there is no oil impact or when the oil flows in the reverse direction, thereby preventing the oil from flowing in the reverse direction, and the rotating component can control the entire valve component to turn 180° to achieve the purpose of changing the flow direction of the oil. At the same time, the design of the clamping block limits the rotation angle to 180°, and the clamping block can cooperate with the limit bolt to limit the position after the turning is completed to prevent the fluid impact force from pushing the mounting plate to flip when the oil flows through again. This structure not only effectively improves the efficiency of changing the flow direction of the one-way valve, but also avoids disassembly, thereby preventing oil leakage.

DETAILED DESCRIPTION

[0038] The following is a specific embodiment of the present invention. People familiar with the technology can easily understand the other advantages and functions of the present invention from the contents disclosed in this specification. Obviously, the described embodiment is a part of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Please refer to Figure 1-Figure 4 Now, a one-way valve with adjustable flow direction disclosed in the utility model is described. The utility model is composed of seven parts, such as Figure 1 , including a connecting pipe 1, a limiting bolt 2, a valve assembly 3, a reset assembly 4, a clamping block 5, a mounting plate 6 and a rotating assembly 7. Pipes are inserted at the front and rear ends of the connecting pipe 1. Clamping blocks 5 are installed on the left and right sides of the inner wall of the connecting pipe 1. The mounting plate 6 is installed in the connecting pipe 1, and the mounting plate 6 is clamped between the two clamping blocks 5. One end of the rotating assembly 7 is inserted in the upper end of the mounting plate 6, and the other end passes through the pipe wall of the connecting pipe 1. The limiting bolts 2 are arranged in pairs, one end of which is inserted in the mounting plate 6, and the other end passes through the side wall of the connecting pipe 1. The valve assembly 3 is transmission-connected to the mounting plate 6. One end of the reset assembly 4 is installed on the rear surface of the mounting plate 6, and the other end of the reset assembly 4 is inserted in the valve assembly 3.

[0040] When the utility model is in use, oil is generated from the production equipment and the cylinder, and the oil will first flow to the valve assembly 3, and then the impact force will cause the valve assembly 3 to move, causing the oil to move in the other direction. When there is no oil flowing in the pipeline or the oil flows back, the reset assembly 4 will bring the valve assembly 3 back to its original position to ensure that the oil will not flow back from the other end. When the fluid needs to reverse the flow, the limit bolt 2 is unscrewed, and then the rotating assembly 7 is rotated to make the mounting plate 6 carry the valve assembly 3 to rotate. After rotating 180°, the block 5 will prevent the mounting plate 6 from continuing to rotate. When it cannot rotate, two limit bolts 2 are used to be symmetrically inserted on both sides to limit the position of the mounting plate 6.

[0041] In a specific embodiment, Figure 2The mounting plate 6 includes a hole slot 61, a clamping slot 62, a slider 63, a clamping plate 64 and a circular plate body 65. The circular plate body 65 is installed in the connecting pipe 1. The circular plate body 65 has clamping slots 62 on both sides. The clamping slots 62 are provided with clamping blocks 5. The clamping plate 64 is installed in one of the clamping slots 62. The clamping block 5 is provided at the front end of the clamping plate 64. The hole slot 61 is provided in the circular plate body 65. The inner surface of the hole slot 61 is provided with a plurality of sliders 63. The valve assembly 3 is connected to the hole slot 61 in a transmission manner. A clamping plate 64 is installed in a clamping slot 62. The clamping plate 64 is used to cooperate with the clamping block 5 to limit the rotation angle of the circular plate body 65. At the same time, the slider 63 is designed to enable the valve assembly 3 to slide and limit the sliding position of the valve assembly 3 to prevent the valve assembly 3 from slipping due to excessive oil pressure.

[0042] On the basis of the previous embodiment, the outer layer of the annular plate body 65 is made of rubber material. Because the annular plate body 65 needs to rotate in the connecting pipe 1, the outer edge of the annular plate body 65 will produce friction with the inner part of the connecting pipe 1 during rotation, so the outer edge is made of rubber material, which can not only reduce friction and avoid wear of the edge of the annular plate body 65, but also the rubber material has a certain elasticity, which can squeeze the inner wall of the connecting pipe 1 during use, effectively preventing oil from flowing out of the gap.

[0043] In a specific embodiment, Figure 3 The valve assembly 3 includes a slide 31, a push plate 32, a guide hole 33 and a mounting cylinder 34. The mounting cylinder 34 is connected to the mounting plate 6 by transmission. The push plate 32 is mounted on the rear surface of the mounting cylinder 34. A through hole is opened in the push plate 32, and one end of the reset assembly 4 is arranged in the through hole. A plurality of slides 31 are opened on the side wall of the mounting cylinder 34, and a plurality of guide holes 33 are opened on the side wall of the mounting cylinder 34. The guide hole 33 is arranged between two slides 31. The valve assembly 3 is applied to the push plate 32 by oil pressure, so that the push plate 32 will move and slide with the mounting cylinder 34, and the slider 63 is arranged in the slide 31. At this time, the slider 63 can limit the moving distance of the mounting cylinder 34. When the mounting cylinder 34 moves, the guide hole 33 is not blocked, and the oil will flow out of the guide hole 33.

[0044] In a specific embodiment, Figure 4The reset assembly 4 includes a moving tube 41, a reset spring 42, a sleeve 43 and an L-shaped connecting block 44. One end of the L-shaped connecting block 44 is installed on the rear surface of the mounting plate 6, and a sleeve 43 is installed at the bottom of the other end. The moving tube 41 is inserted at the front end of the sleeve 43. The valve assembly 3 is connected to the outer surface of the moving tube 41. The moving tube 41 is transmission-connected to the outside of the sleeve 43. The moving tube 41 and the interior of the sleeve 43 are hollow structures. The reset spring 42 is installed in the hollow structure. The front end of the reset spring 42 is installed at the rear end of the front plate of the moving tube 41, and the rear end of the reset spring 42 is installed at the front end of the rear plate of the sleeve 43. After the valve assembly 3 moves, the moving tube 41 moves backward and squeezes the return spring 42. When there is no oil or the oil flows back, the return spring 42 will push the moving tube 41 forward with the valve assembly 3 under the action of the return spring 42, so that the valve assembly 3 returns to the closed state before use. At this time, the push plate 32 is flush with the rear surface of the mounting plate 6, and the slider 63 is used to limit the movement of the valve assembly 3, so that the oil cannot flow back.

[0045] In a specific embodiment, the rotating assembly 7 includes a connecting rod and a knob, one end of the connecting rod passes through the connecting pipe 1 and is inserted into the mounting plate 6, and the other end of the connecting rod is installed with a knob. When changing the flow direction of the one-way valve, by rotating the knob, the knob will drive the connecting rod to rotate, and the connecting rod will drive the mounting plate 6 to rotate, so as to achieve the purpose of reversing.

[0046] In a specific embodiment, a plurality of small holes are opened on the side wall of the connecting pipe 1, and the rotating assembly 7 and the limiting bolt 2 are inserted into the small holes. The plurality of small holes are provided to facilitate the insertion of the limiting bolt 2, so that the limiting bolt 2 can limit the rotation of the mounting plate 6.

[0047] Although the utility model has been described in detail above with general descriptions and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the utility model. Therefore, these modifications or improvements made without departing from the spirit of the utility model are within the scope of protection claimed by the utility model.
