Description

Technical Field

[0001] The utility model belongs to the technical field of electromagnetic valves, and more specifically relates to a fast opening and closing electromagnetic valve. Background Art

[0002] At present, many solenoid valves use relatively high-power solenoid coils in order to achieve rapid response. However, if the response speed of the solenoid valve is required to be lower, a low-power solenoid coil is selected.

[0003] The power of the electromagnetic coil can be achieved by increasing or decreasing the number of turns of the electromagnetic coil. Therefore, solenoid valves of different powers have different sizes, resulting in a large number of models. Customers can only choose from the existing models and cannot adjust the power of the solenoid valve according to their actual situation. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a fast opening and closing solenoid valve to meet the needs of users to adjust the total power of the solenoid valve by themselves.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a quick opening and closing solenoid valve, comprising a first shell, a plurality of second shells, an end cover, a plurality of electromagnetic coils, a main piston rod and a plurality of auxiliary piston rods, the second shell is detachably connected to the first shell, the end cover is detachably connected to the first shell or the second shell, the plurality of electromagnetic coils are respectively located in the first shell and the plurality of shells, the auxiliary piston rod is detachably connected to the main piston rod, the plurality of auxiliary piston rods are detachably connected to each other, and a reset spring is arranged between the main piston rod and the end cover.

[0006] Furthermore, a coil cavity is provided in each of the first shell and the second shell, and the electromagnetic coil is located in the coil cavity.

[0007] Furthermore, the end cover and the second shell are both provided with elastic pressure rings corresponding to the electromagnetic coil.

[0008] Furthermore, the second shell is threadedly connected to the first shell, and the end cover is threadedly connected to the first shell or the second shell.

[0009] Furthermore, both the main piston rod and the auxiliary piston rod are provided with threaded holes, and the auxiliary piston rod is provided with a threaded column.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows: the main piston rod is slidably connected to the first shell, and the user can connect the second shell to the first shell according to practical needs, and place an electromagnetic coil on the second shell, connect the auxiliary piston rod to the main piston rod, and make the auxiliary piston rod extend into the middle of the electromagnetic coil in the second shell, and then place a reset spring between the auxiliary piston rod and the end cover, and finally connect the end cover to the second shell, so as to increase the electromagnetic coil and the main piston rod, so that the electromagnetic force on the main piston rod is greater, and the valve reacts faster, meeting the user's need to adjust the total power of the solenoid valve by himself; of course, the end cover can also be connected to the first shell, the electromagnetic coil is installed in the first shell, and the main piston rod extends into the electromagnetic coil. At this time, the electromagnetic force on the main piston rod is minimal. BRIEF DESCRIPTION OF THE DRAWINGS
