A solenoid valve is an integrated device that contains an electromechanical solenoid that can drive a pneumatic or hydraulic valve or an electromagnetic switch.

A solenoid valve is an electromagnetically controlled device and is a basic automation component used to control fluids. It is an actuator and is not limited to hydraulic or pneumatic.

DETAILED DESCRIPTION

[0021] The following will clearly and completely describe the technical solution of the utility model in conjunction with the drawings in the utility model. In addition, the forms of the various structures recorded in the following embodiments are merely illustrative. The electromagnetic integrated valve involved in the utility model is not limited to the various structures recorded in the following embodiments. All other implementations obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the utility model.

[0022] Reference Figure 1-Figure 3 The utility model provides an electromagnetic integrated valve, including an integrated valve block 1. The oil in the oil cylinder will enter the integrated valve block 1 through the oil inlet 101 in the integrated valve block 1 and circulate in sequence through the first two-position five-way electromagnetic reversing valve 2, the second two-position five-way electromagnetic reversing valve 3, the two-position four-way electromagnetic reversing valve 4, the second two-position two-way electromagnetic reversing valve 5, and the first two-position two-way electromagnetic reversing valve 6. The circulated oil flows back to the oil cylinder through the oil outlet 102 in the integrated valve block 1. The first two-position five-way electromagnetic reversing valve 2 and the second two-position five-way electromagnetic reversing valve 3 have the same structure. The first two-position five-way electromagnetic reversing valve 2 and the second two-position five-way electromagnetic reversing valve 3 can work independently. The second two-position two-way electromagnetic The reversing valve 5 has the same structure as the first two-position two-way solenoid reversing valve 6. The second two-position two-way solenoid reversing valve 5 and the first two-position two-way solenoid reversing valve 6 can work independently. The oil must first pass through the flow control valve before entering between the first two-position five-way solenoid reversing valve 2 and the second two-position five-way solenoid reversing valve 3. The side of the first two-position five-way solenoid reversing valve 2 is fixedly connected to the second two-way quantitative hydraulic motor 10, and the side of the second two-position five-way solenoid reversing valve 3 is fixedly connected to the first two-way quantitative hydraulic motor 9. The liquid passing through the first two-position five-way solenoid reversing valve 2 and the second two-position five-way solenoid reversing valve 3 is extracted by the second two-way quantitative hydraulic motor 10 and the first two-way quantitative hydraulic motor 9.

[0023] In the embodiment of the present application, the solenoid valve group of each performance unit is controlled to achieve the buffering and lifting effect of the plunger cylinder supported by the vehicle body and the follow-up switching conversion of the system oil circuit. By driving the variable rotation brake, the drive component or power unit is opened or closed at a very fast speed, thereby enabling rapid control of the armored engineering vehicle. The electromagnetic integrated valve group meets multiple functional requirements such as waterproofing, salt resistance, and corrosion resistance.

[0024] Reference Figure 1 The amount of oil extracted by the second bidirectional quantitative hydraulic motor 10 and the first bidirectional quantitative hydraulic motor 9 is compared with the flow controlled by the flow control valve. The second bidirectional quantitative hydraulic motor 10 and the first bidirectional quantitative hydraulic motor 9 do not interfere with each other when working, and the second bidirectional quantitative hydraulic motor 10 and the first bidirectional quantitative hydraulic motor 9 can control the oil in the integrated valve block 1 at the same time. By controlling the amount of oil extracted by the second bidirectional quantitative hydraulic motor 10 and the first bidirectional quantitative hydraulic motor 9 when working and the flow through the flow control valve, it can be determined whether there is a leakage in the entire hydraulic system to ensure accuracy during work. The second bidirectional quantitative hydraulic motor 10 and the first bidirectional quantitative hydraulic motor 9 are used to work, which can provide greater force. Therefore, when used in clamping engineering vehicles, it can also ensure that they can respond quickly.

[0025] Reference Figure 1 When the oil enters the two-position four-way solenoid reversing valve 4 from the integrated valve block 1, it needs to pass through the overflow valve. The bottom end of the two-position four-way solenoid reversing valve 4 is fixedly connected with the overflow valve, and the bottom end of the overflow valve is fixedly connected to the top of the integrated valve block 1. The side of the two-position four-way solenoid reversing valve 4 is fixedly connected with a booster 11, and the oil flowing through the two-position four-way solenoid reversing valve 4 is controlled by the booster 11. The two-position four-way solenoid reversing valve 4 is located in the middle above the integrated valve block 1, and one side of the two-position four-way solenoid reversing valve 4 is fixedly connected with two two-position five-way solenoid reversing valves, and the other side of the two-position four-way solenoid reversing valve 4 is fixedly connected with a booster 11. There are two two-position two-way solenoid reversing valves fixedly connected on the side, and the two-position four-way solenoid reversing valve 4 is located in the middle above the integrated valve block 1. Therefore, the two-position four-way solenoid reversing valve 4 needs to be connected on both sides. The pressure on the two-position four-way solenoid reversing valve 4 is relatively large, so a booster 11 is added to ensure that the two-position four-way solenoid reversing valve 4 has sufficient pressure to allow the oil to flow during operation. In addition, when the booster 11 provides pressure to make the overall pressure of the hydraulic system constant, when the system fails and the pressure is too high, an overflow valve is added to the two-position four-way solenoid reversing valve 4 to relieve the pressure, thereby ensuring its stable operation.

[0026] Reference Figure 1A second plunger cylinder 8 is fixedly connected to the side of the second two-position two-way electromagnetic reversing valve 5, and a first plunger cylinder 7 is fixedly connected to the side of the first two-position two-way electromagnetic reversing valve 6. The second plunger cylinder 8 and the first plunger cylinder 7 can work independently, and a booster can be added above the first plunger cylinder 7 and the second plunger cylinder 8. The first plunger cylinder 7 and the second plunger cylinder 8 are used to provide pressure. The pressure that the first plunger cylinder 7 and the second plunger cylinder 8 can provide is relatively large, and a booster can be added above the first plunger cylinder 7 and the second plunger cylinder 8 to ensure that there is sufficient pressure for work.

[0027] Reference Figure 1 and Figure 2 The top of the oil inlet 101 and the bottom of the oil outlet 102 are in the same plane. The wall thickness of all oil passages in the integrated valve block 1 is greater than 5 mm. The material of the integrated valve block 1 is 45 steel, and the integrated valve block 1 needs to be heat-treated and tempered. The heat treatment hardness is 240-285HBW. The oil inlet 101 and the oil outlet 102 are set as two layers to prevent the two from communicating with each other. The integrated valve block 1 is heat-treated and the material is selected. Therefore, when it is working, the pressure of the oil flowing is relatively high and it will not cause damage to the integrated valve block 1, thereby extending the service life of the integrated valve block 1.

[0028] Reference Figure 1 , the first two-position five-way solenoid reversing valve 2, the second two-position five-way solenoid reversing valve 3, the two-position four-way solenoid reversing valve 4, the second two-position two-way solenoid reversing valve 5, and the first two-position two-way solenoid reversing valve 6 need to be assembled with an integrated injection molded shell when in use, and the first two-position five-way solenoid reversing valve 2, the second two-position five-way solenoid reversing valve 3, the two-position four-way solenoid reversing valve 4, the second two-position two-way solenoid reversing valve 5, and the first two-position two-way solenoid reversing valve 6 are integrated. The directional valve 3, the two-position four-way solenoid reversing valve 4, the second two-position two-way solenoid reversing valve 5, and the first two-position two-way solenoid reversing valve 6 are integrated, and the surfaces of the first two-position five-way solenoid reversing valve 2, the second two-position five-way solenoid reversing valve 3, the two-position four-way solenoid reversing valve 4, the second two-position two-way solenoid reversing valve 5, and the first two-position two-way solenoid reversing valve 6 are integrated injection molded shells, so they have good sealing performance when in use, and are provided with a plurality of different solenoid valves, so that they can meet the different requirements of armored vehicles when in use, and the overall volume is small.

[0029] Reference Figure 3 When the oil in the oil cylinder enters the oil inlet 101, it needs to pass through the cooler, and the oil passing through the cooler needs to be tested by a pressure gauge. An air filter is provided in the oil cylinder.

[0030] In the embodiment of the present application, an air filter is provided in the oil cylinder to prevent dust in the air from entering the hydraulic oil and affecting the circulation of the oil. The oil is cooled by a cooler when it circulates to prevent the pressure from increasing due to excessive temperature, thereby preventing danger. The oil can also be detected by a pressure gauge to ensure the safety of the system during operation.
