Description

Technical Field

[0001] The utility model relates to the technical field of electro-hydraulic valves, and in particular to a 16-diameter electro-hydraulic valve with a new structure. Background Art

[0002] The electro-hydraulic valve is a device that converts electrical signals into hydraulic energy. It adjusts the flow direction and flow rate of hydraulic oil by controlling the magnitude and direction of the current. It is an automated basic component used to control the direction of fluid in oil and chemical loading systems. It is widely used in automated sending and receiving systems in industries such as petroleum, chemical, fire protection, and water supply systems. The 16-diameter electro-hydraulic valve is widely used in industrial hydraulics, but the traditional structure of the electro-hydraulic valve has the following problems:

[0003] (1) The traditional electro-hydraulic valve body structure is an end cover structure, the processing procedure is complicated, and there are many parts that match it. During the assembly process, problems such as mixed assembly and missing assembly are very likely to occur.

[0004] (2) Since the electro-hydraulic valve requires end covers on both sides to ensure that the pilot control oil can reach both ends of the valve core, a large number of sealing grooves need to be designed. However, since the sealing cover structure uses a large number of sealing rings, the aging of the sealing ring structure will cause a large amount of product oil leakage. Oil seepage often occurs on the joint surface of the end cover, which reduces the service life of the product and poses a quality risk.

[0005] (3) The material of the traditional electro-hydraulic valve end cover is QT500. When working, the main valve core moves left and right, which has a large impact force and a risk of end cover bursting. The impact resistance is low.

[0006] (4) The oil control part of the traditional structure electro-hydraulic valve is a processed flow channel, and the flow channels of the valve body are all processed later. The pilot flow channel needs to be additionally processed, which leads to processing uncertainty, poor product stability and high processing cost.

[0007] (5) The traditional valve body needs to be processed multiple times and can only be realized by machining process holes, which not only makes the electro-hydraulic valve bulky and rough in appearance, but also wastes a lot of materials and increases processing costs.

[0008] In order to solve the above problems, it is particularly necessary to design a new structure 16-diameter electro-hydraulic valve. Utility Model Content

[0009] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a new structure 16-diameter electro-hydraulic valve with a simple structure, reasonable design, simplified processing procedures, avoid oil leakage, enhance impact strength, improve product stability and quality, extend service life, avoid loss, reduce processing costs, have strong practicality, and be easy to promote and use.

[0010] In order to achieve the above-mentioned purpose, the utility model is realized through the following technical scheme: a new structure 16-diameter electro-hydraulic valve, including a valve body, a valve core, a screw plug, a cast flow channel and a gasket, screw plugs are installed at both ends of the valve body, the screw plugs are fixed to both sides of the valve body by spiral rotation, a valve core is installed in the valve body, a gasket is arranged at the connection between the valve core and the screw plug, and an integrally formed cast flow channel is arranged inside the valve body, and the flow channel is all constructed by casting.

[0011] Preferably, the screw plug is a 45 steel structure screw plug. The electro-hydraulic valve adopts a screw plug seal set on the valve body. The 45 steel is modulated to greatly improve the impact resistance.

[0012] The beneficial effects of the utility model are as follows: the device is beautiful and light as a whole, with a delicate appearance, which greatly reduces the processing procedures and avoids the occurrence of oil leakage. At the same time, the functions are more stable and reliable, which greatly improves the product quality and prolongs the service life. The materials used are simple, which avoids loss and saves processing and manufacturing costs, and has broad application prospects. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The utility model is described in detail below with reference to the accompanying drawings and specific implementation methods;

[0014] Figure 1 It is a structural schematic diagram of the utility model. DETAILED DESCRIPTION

[0015] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0016] Reference Figure 1 , this specific implementation adopts the following technical scheme: a new type of structure 16-diameter electro-hydraulic valve, including a valve body 1, a valve core 2, a screw plug 3, a cast flow channel 4 and a gasket 5, screw plugs 3 are installed at both ends of the valve body 1, and the screw plugs 3 are fixed to both sides of the valve body 1 by spiral rotation, a valve core 2 is installed in the valve body 1, and a gasket 4 is provided at the connection between the valve core 2 and the screw plug 3, and the interior of the valve body 1 is provided with an integrally formed cast flow channel 4, which is all cast; the screw plug 3 is a 45 steel structure screw plug, and the electro-hydraulic valve adopts a screw plug type seal arranged on the valve body 1, and the 45 steel is modulated, which greatly improves the impact strength and has no risk of bursting.

[0017] The control oil passage adopted in this specific implementation is a casting structure, and no additional processing of the pilot flow passage is required. Therefore, the end cover structure at both ends of the valve body can be replaced with a screw plug structure, which can greatly avoid the oil leakage phenomenon at the end cover of the traditional valve body. At the same time, due to the particularity of the flow passage of the new electro-hydraulic valve, the oil control method of the electro-hydraulic valve is very different from that of the original valve body. The processing method of the electro-hydraulic valve body is more convenient, and it only needs to open up the flow passage of the control oil. Specifically, its technical advantages are:

[0018] (1) The screw plug sealing structure is adopted, which is not only simpler and more efficient to assemble, but also has a stable screw plug structure. It does not need to use a large number of sealing grooves, which reduces the types of materials and reduces the problems of mixed installation and leakage during assembly. It effectively avoids the poor sealing and oil leakage of the end cover of the traditional electro-hydraulic valve, and solves the oil leakage problem caused by the aging of the sealing ring of the traditional end cover structure, thereby extending the service life of the product and reducing the risk of quality problems.

[0019] (2) The electro-hydraulic valve has a cast flow channel, and no additional processing of the pilot flow channel is required. The processing method is simple, which avoids the loss and uncertainty caused by processing, improves the stability of the product, and saves a lot of labor costs.

[0020] (3) The control oil flow path of the electro-hydraulic valve only needs to process two process holes in the P and T oil paths of the pilot valve body. Compared with the traditional valve body that needs to process multiple process holes, it not only simplifies the processing procedure, but also makes the electro-hydraulic valve structure simpler, more refined, more beautiful, lighter, and more integrated in appearance. At the same time, it can also save a lot of materials and save material costs.

[0021] In summary, the electro-hydraulic valve uses simple materials and is more integrated. The one-piece casting valve body makes the valve function reliable. The valve body flow channels are all cast, which eliminates post-processing problems, improves product stability, and reduces production costs and processing uncertainties. It has broad market application prospects.

[0022] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model.
