Problems solved by technology

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the fact that the solenoid valve opening distance in the prior art is usually non-adjustable after reaching the maximum, so that it cannot meet the user's control requirements for the gas flow rate, which will cause waste of gas supply resources. In order to solve the problem of poor performance, it provides a combined two-stage multi-functional solenoid valve device that realizes multi-level regulation of gas flow, meets the user's control requirements for gas flow, has a wide range of applications, and has good performance.

Embodiment 1

[0043] Below in conjunction with accompanying drawing this embodiment is described in detail:

[0044] This embodiment provides as Figure 1-5 The shown combined double-stage multifunctional solenoid valve device includes a valve body 1, a ventilation pipeline 10 arranged in the valve body 1, and at least one valve port 11 arranged in the ventilation pipeline 10 , and at least one valve driving device for closing or opening the valve port, wherein the valve driving device comprises:

[0045] The valve assembly 2 includes a valve disc 21 disposed on the valve port 11 which can be opened or closed, and a transmission rod 22 fixedly connected to the valve disc 21;

[0046] The first electromagnetic valve core 3 is movably connected with the transmission rod 22 in the valve body 1, and when the first electromagnetic valve core 3 moves upward along the axial direction of the transmission rod 22, it drives the transmission rod toward Move away from the valve port 11, and drive the...

Embodiment approach

[0050] As a preferred embodiment, the first electromagnetic valve core 3 and the second electromagnetic valve core 4 are energized successively, and the connection between the first electromagnetic valve core 3 and the second electromagnetic valve core 4 and the transmission rod 22 A limit transmission structure 5 is provided respectively, and the first electromagnetic valve core 3 or the second electromagnetic valve core 4 drives the transmission rod 22 to move synchronously through the limit transmission structure 5 when moving upwards. When a solenoid valve core 3 moves up, it first drives the transmission rod to move up to the first-stage stroke, and then when the second solenoid valve core 4 moves up, it drives the transmission rod to move up to the second-stage stroke. Figure 1-2 A closing spring 23 is provided between the valve body 1 and the valve disc 21, and the closing spring 23 drives the valve when the first electromagnetic valve core 3 and / or the second electroma...

Abstract

The invention discloses a combined type two-stage multifunctional electromagnetic valve device. The combined type two-stage multifunctional electromagnetic valve device comprises a valve driving device used for closing or opening a valve port, the valve driving device comprises a valve disc, a transmission rod, a first electromagnetic valve element and a second electromagnetic valve element, and the transmission rod is driven by the first electromagnetic valve element to move upwards. The valve disc opens a first stage stroke at the valve port, and drives the transmission rod to continue to move up through the second electromagnetic valve element to open the valve disc in the first stage stroke to a second stage stroke. By adopting the technical scheme, the electromagnetic valve device realizes the flow switching function by adjusting and controlling the two-stage stroke of the valve disc. Therefore, switching control over the gas flow is achieved, ignition and detonation risks causedby the fact that the instantaneous discharge amount of gas is too large are avoided, controllability is good, use is safe and reliable, unnecessary waste of gas resources is avoided, the multi-stage control requirement of customers for the gas flow can be met, and the application range is wide.

Description

technical field [0001] The invention relates to the technical field of gas solenoid valves, in particular to a combined double-stage multifunctional solenoid valve device. Background technique [0002] Solenoid valve is an industrial equipment controlled by electromagnetic. It is an automatic basic component used to control fluid. It belongs to actuator. It is used to adjust the direction, flow, speed and other parameters of medium in industrial control system. It can be applied to steam pipeline, gas In pipeline transportation systems such as pipelines and natural gas pipelines, it is widely used in our daily life. [0003] In daily life and industrial production, most of the gas valve devices commonly used by people adopt a direct-acting solenoid valve structure. This solenoid valve is mainly composed of an electromagnetic coil, a magnetic core and a valve core, and also includes one or several holes. The valve body, the return spring between the valve body and the valve ...
