Abstract
Description
Technical Field
[0001] This utility model belongs to the field of electromagnetic valve technology, and more specifically relates to a gas electromagnetic valve. Background Technology
[0002] In gas transmission systems, gas solenoid valves are used to control the on / off flow of gas. These solenoid valves are typically installed on the main transmission pipeline. Currently, most gas solenoid valves do not have segmented flow control capabilities and have limited functionality. Utility Model Content
[0003] To address the shortcomings of existing technologies, this utility model provides a gas solenoid valve that can change different delivery flow rates according to requirements.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a gas solenoid valve, comprising a drive housing and a delivery housing, wherein a slidable first drive core and a second drive core are disposed within the drive housing, and a first electromagnetic coil and a second electromagnetic coil corresponding to the first drive core and the second drive core are disposed within the delivery housing, wherein a delivery cavity is disposed within the delivery housing, and the two ends of the delivery cavity are respectively the connection ports of the delivery housing, wherein a first valve port and a second valve port are disposed within the delivery cavity, and the first valve port is smaller than the second valve port, and a first valve and a second valve corresponding to the first valve port and the second valve port are respectively disposed on the first drive core and the second drive core.
[0005] Furthermore, a fixing plate is provided inside the drive housing. The fixing plate seals and separates the cavity inside the drive housing into an electromagnetic cavity and a drive cavity. The electromagnetic coil is located inside the electromagnetic cavity. The drive cavity is connected to the conveying cavity. The first drive iron core and the second drive iron core pass through the fixing plate from the electromagnetic cavity to the drive cavity. A return spring is sleeved on both the first drive iron core and the second drive iron core. The return spring is located between the fixing plate and the valve. The elastic force of the return spring drives the first drive iron core and the second drive iron core to seal the valve port when there is no external force.
[0006] Furthermore, both the first and second valves are equipped with rubber gaskets.
[0007] Furthermore, the drive housing is provided with fixing blocks corresponding to the first drive core and the second drive core respectively, and the first drive core and the second drive core are slidably connected to the fixing blocks.
[0008] Furthermore, the first electromagnetic coil is located below the second electromagnetic coil on one side.
[0009] Compared with the prior art, the beneficial effects of this utility model are: the first electromagnetic coil and the second electromagnetic coil can control the first driving iron core and the second driving iron core separately, thereby driving the first valve and the second valve to open and close the first valve port and the second valve port respectively, thereby realizing the change of different conveying flow rates according to the needs.

[0014] Reference Figure 1 The present invention will be further described below.
[0015] A gas solenoid valve includes a drive housing 1 and a delivery housing 2. The drive housing 1 is provided with a slidable first drive core 3 and a second drive core 4. The delivery housing 2 is provided with a first electromagnetic coil 5 and a second electromagnetic coil 6 corresponding to the first drive core 3 and the second drive core 4, respectively. The delivery housing 2 is provided with a delivery cavity 7, the two ends of which are the connection ports of the delivery housing 2. The delivery cavity 7 is provided with a first valve port 8 and a second valve port 9, and the first valve port 8 is smaller than the second valve port 9. The first drive core 3 and the second drive core 4 are respectively provided with a first valve 10 and a second valve 11 corresponding to the first valve port 8 and the second valve port 9.
[0016] like Figure 1 As shown, the first electromagnetic coil 5 and the second electromagnetic coil 6 can independently control the first driving iron core 3 and the second driving iron core 4, thereby driving the first valve 10 and the second valve 11 to open and close the first valve port 8 and the second valve port 9, respectively. When only the first valve 10 is opened, the flow rate of gas from one end connection port of the conveying housing 2 to the other end connection port is minimal because the first valve port 8 is relatively small. When only the second valve 11 is opened, the second valve port 9 is larger, thus increasing the flow rate compared to opening the first valve 10 alone. When the first valve 10 is opened, the second valve 11 can also be opened when needed, so that both valves are open to achieve the maximum flow rate. Alternatively, both valves can be opened simultaneously from the beginning to immediately achieve the maximum flow rate, thereby realizing the ability to change the conveying flow rate according to demand.
[0017] like Figure 1 As shown in the preferred embodiment, a fixing plate 12 is provided inside the drive housing 1. The fixing plate 12 seals and separates the cavity inside the drive housing 1, which is divided into an electromagnetic cavity 13 and a drive cavity 14. The electromagnetic coil is located inside the electromagnetic cavity 13. The drive cavity 14 is connected to the conveying cavity 7. The first drive core 3 and the second drive core 4 pass through the fixing plate 12 from the electromagnetic cavity 13 to the drive cavity 14. A return spring 15 is sleeved on both the first drive core 3 and the second drive core 4. The return spring 15 is located between the fixing plate 12 and the valve. The elastic force of the return spring 15 drives the first drive core 3 and the second drive core 4 to seal the valve port when there is no external force.
[0018] like Figure 1 As shown, specifically, the drive housing 1 is a split type, which can be composed of multiple housings, and the housings are connected to each other by flange sealing.
[0019] Specifically, the drive housing 1 and the conveyor housing 2 are sealed together.
[0020] Specifically, the drive core and the fixed plate 12 are connected by a sealed sliding connection, and a sealing ring can be provided on the hole wall of the fixed plate 12.
[0021] Specifically, an electronic control unit is also provided on the top of the drive housing 1. Figure 1 The dashed section is used to connect the electromagnetic coil and control the on / off state of the electromagnetic coil.
[0022] In this example, preferably, both the first valve 10 and the second valve 11 are provided with rubber gaskets to improve valve sealing.
[0023] like Figure 1 As shown in the example, preferably, the drive housing 1 is provided with a fixing block 16 corresponding to the first drive core 3 and the second drive core 4 respectively, and the first drive core 3 and the second drive core 4 are slidably connected to the fixing block 16.
[0024] like Figure 1 As shown, in this example, preferably, the first electromagnetic coil 5 is located below the second electromagnetic coil 6 on one side, reducing the volume increase caused by side-by-side placement.
[0025] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
