Description

Technical Field

[0001] This utility model relates to the field of directional valve technology, and more specifically, to a cartridge-type directional valve. Background Technology

[0002] Directional control valves, also known as operating valves or control valves, are used in hydraulic support systems to control the direction of fluid flow, enabling different actions such as lifting, pushing, and pulling of the hydraulic support.

[0003] In response, Chinese patent application number CN214787455U discloses a novel cartridge-type metal ring-sealed directional valve, comprising a valve body, a valve core, a valve sleeve, a housing, and valve chambers. Valve chambers are provided on both sides of the valve body, with the top of each chamber extending to the outside of the valve body. A flow port is provided inside the valve body below each valve chamber, with the bottom of the flow port extending to the outside of the valve body. A valve sleeve is provided at one end of each valve chamber, with the top of the sleeve extending to the outside of the valve chamber. A valve core is located inside the valve chamber below the sleeve. A return hole is located at the center of the valve body, and an inlet hole is located inside the valve body above the return hole. A housing is installed at the top of the valve body, with a handle installed at the center of the top of the housing. This invention not only improves the sealing performance of the directional valve during use, achieving rapid reset, but also enhances the convenience of its use.

[0004] However, in actual use, the operation is relatively cumbersome, and the reversing operation cannot be performed quickly. In addition, there is no reminder function when reversing, and the reversing valve requires strong stability during installation.

[0005] Therefore, in order to solve the above-mentioned technical problems, this application proposes a cartridge-type directional valve. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a cartridge-type directional valve.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a cartridge-type directional valve, comprising a directional valve body, wherein a first discharge pipe and a second discharge pipe are arranged sequentially from top to bottom on the right side surface of the directional valve body, and a feed pipe is arranged on the left side surface of the directional valve body, and a cylinder body is fixedly connected to the top surface of the inner wall of the directional valve body.

[0008] Insert plate, the insert plate is installed on the lower surface of the cylinder body, and the insert plate has a discharge hole inside;

[0009] A base plate is installed on the inner bottom wall of the reversing valve body. A support plate is fixedly connected to the top surface of the base plate, and a pressure sensor is installed on the top surface of the support plate.

[0010] Preferably, the support plate has a flow groove inside, and a guide frame is fixedly connected to the left side surface of the support plate.

[0011] Preferably, a guide groove is provided on the left side surface of the insert plate, and a conveying groove is provided on the inner side wall of the insert plate.

[0012] Preferably, the conveying trough and the discharge hole are interconnected, and the discharge hole and the first discharge pipe have the same dimensions.

[0013] Preferably, a connecting plate is fixedly connected to the front surface of the reversing valve body, and a top plate is fixedly connected to the top surface of the connecting plate.

[0014] Preferably, the upper and lower ends of the connecting plate are fixedly connected to a fixing plate, and the fixing plate is provided with fixing bolts inside.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In this utility model, through the arrangement of a reversing valve body, a first discharge pipe, a second discharge pipe, a feed pipe, a cylinder body, a cartridge plate, a discharge hole, a bottom plate, a support plate, a pressure sensor, a flow channel, and a guide frame, it is possible to quickly reverse the discharge through the first and second discharge pipes. The overall operation is relatively simple. During use, the cylinder body can drive the cartridge plate to move downwards. When the cartridge plate descends and abuts against the upper surface of the bottom plate, the top surface of the inner wall of the cartridge plate will abut against the support plate and the pressure sensor. At this time, the pressure sensor is subjected to pressure, so the cartridge plate will abut against the lower surface of the bottom plate. Then, the cylinder body stops moving, and the discharge hole aligns with the first discharge pipe, allowing material to be conveyed through the first discharge pipe. At the same time, the right side of the insert plate seals the second discharge pipe, resulting in a good overall reversing effect. When the second discharge pipe needs to discharge, the cylinder body drives the insert plate to rise, disengaging the discharge hole from the first discharge pipe. The insert plate then seals the first discharge pipe, allowing the second discharge pipe to discharge. The design of the flow channel and guide frame ensures stable conveying of materials fed from inside the feed pipe, demonstrating the practicality of the design.

[0017] 2. In this utility model, through the design of the guide groove, conveying groove, connecting plate, top plate, fixing plate, and fixing bolts, during use, the guide groove and conveying groove can independently feed material into the discharge hole. At this time, the feed pipe is above the guide groove, so the feed pipe directly conveys the material into the guide groove and conveying groove, and then conveys it into the first discharge pipe through the discharge hole. During installation, the two sets of fixing plates are first attached to the mounting plate and fixed by fixing bolts. Then, the top plate strengthens the stability between the reversing valve body and the connecting plate, so the overall installation effect of the reversing valve body is better, reflecting the functionality of the design.

[0025] Reference Figures 1 to 5 The present invention provides a further description of an embodiment of a cartridge-type directional valve.

[0026] This utility model provides a cartridge-type reversing valve. The reversing valve body 1, cartridge plate 6, pressure sensor 10 and cartridge plate 6 used in this application are all products that can be directly purchased on the market. Their principles and connection methods are existing technologies known to those skilled in the art, so they will not be described in detail here. The reversing valve body 1 includes a first discharge pipe 2 and a second discharge pipe 3 arranged sequentially from top to bottom on the right side surface of the reversing valve body 1. A feed pipe 4 is arranged on the left side surface of the reversing valve body 1. A cylinder body 5 is fixedly connected to the top surface of the inner wall of the reversing valve body 1.

[0027] Insert plate 6 is installed on the lower surface of cylinder body 5, and a discharge hole 7 is provided inside the insert plate 6;

[0028] The base plate 8 is installed on the inner bottom wall of the reversing valve body 1. A support plate 9 is fixedly connected to the top surface of the base plate 8. A pressure sensor 10 is installed on the top surface of the support plate 9. The cylinder body 5 can drive the cartridge plate 6 to move downward. When the cartridge plate 6 descends and touches the upper surface of the base plate 8, the top surface of the inner wall of the cartridge plate 6 will touch the support plate 9 and the pressure sensor 10. At this time, the pressure sensor 10 is under pressure, so the cartridge plate 6 will touch the lower surface of the base plate 8. Then, the cylinder body 5 stops moving. At the same time, the discharge hole 7 will be aligned with the first discharge pipe 2, so that the material can be conveyed and discharged through the first discharge pipe 2. At the same time, the right side of the cartridge plate 6 will seal the second discharge pipe 3. The overall reversing effect is good. When the second discharge pipe 3 needs to discharge, the cylinder body 5 drives the cartridge plate 6 to rise. At this time, the discharge hole 7 is separated from the first discharge pipe 2. The cartridge plate 6 seals the first discharge pipe 2, and the second discharge pipe 3 can discharge.

[0029] The support plate 9 has a flow channel 11 inside, and a guide frame 12 is fixedly connected to the left side surface of the support plate 9. The design of the flow channel 11 and the guide frame 12 enables the material fed from the feed pipe 4 to be transported stably.

[0030] A guide groove 14 is provided on the left side surface of the insert plate 6, and a conveying groove 15 is provided on the inner side wall of the insert plate 6. The conveying groove 15 is connected to the discharge hole 7. The discharge hole 7 and the first discharge pipe 2 have the same size. Through the design of the guide groove 14 and the conveying groove 15, material can be fed into the discharge hole 7 independently. At this time, the feed pipe 4 is above the guide groove 14, so the feed pipe 4 directly conveys the material into the guide groove 14 and the conveying groove 15 during feeding, and then conveys it into the first discharge pipe 2 through the discharge hole 7.

[0031] A connecting plate 16 is fixedly connected to the front surface of the directional valve body 1, a top plate 17 is fixedly connected to the top surface of the connecting plate 16, and fixing plates 18 are fixedly connected to both the upper and lower ends of the connecting plate 16. Fixing bolts 19 are provided inside the fixing plates 18. During installation, the two sets of fixing plates 18 are first attached to the mounting plate and fixed by the fixing bolts 19. Then, the top plate 17 is used to enhance the stability between the directional valve body 1 and the connecting plate 16, so that the overall installation effect of the directional valve body 1 is better.

[0032] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
