[0002] A solenoid valve is an actuator used to control the pressure, flow rate and flow direction of a fluid in a control fluid system. A solenoid valve is usually used to control the opening and closing of a valve fluid valve to control the conduction of the fluid in the system.

[0003] In order to save production costs or improve installation efficiency, existing valve control modules often use a single or two solenoid valves in series to control the conduction and closing of the valve. However, when the solenoid valve in the valve control module fails due to various reasons, the control of the valve in the fluid system will fail, resulting in irreversible fluid loss or fluid blockage, and in severe cases, causing serious production accidents such as fluid pipeline rupture. Utility Model Content

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0027] Example 1

[0028] See also Figure 1-Figure 5 The utility model provides an embodiment: a linkage control interlocking valve control module, comprising:

[0029] The rack 100 adjusts the material according to the actual production demand. In the default state, stainless steel is used. Screw holes are provided on the rack 100, and the rack 100 can be detachably connected to the installation position by threaded connection. If disassembly is not required, welding can also be used to reinforce the connection between the rack 100 and the installation position.

[0030] The fluid pipe 200 is arranged on one side of the frame 100. The frame 100 can be provided with a pipe hole so that the fluid pipe 200 can pass through the frame 100 to achieve relative fixation between the fluid pipe 200 and the frame 100. The fluid pipe 200 includes a three-way joint 210, a flow guide pipe 220 and an output end 230. The three-way joint 210 is fixed on one side of the frame 100. One end of the three-way joint 210 is a fluid input end, the other end is used to connect the flow guide pipe 220, and the remaining end is connected to the output end 230. The remaining end can directly transport the incoming fluid to the output end 230. The flow guide pipe 220 is used to carry the transmission fluid. The flow guide pipe 220 is composed of a solenoid valve group 300 and an isolation valve. The valve group 400 is controlled to realize the conduction and closing of the guide tube 220. The output end 230 includes an output end body 231, a first muffler 232, a second muffler 233 and a straight-through sleeve 234. The output end body 231 connects the guide tube 220 and the other end of the three-way joint 210. The first muffler 232 and the second muffler 233 are arranged on the output end body 231. The first muffler 232 and the second muffler 233 are used to reduce the noise generated by the fluid in the output end 230. The straight-through sleeve 234 is arranged on one side of the output end body 231, preferably on the outside of the frame 100, so that the output end body 231 can output the fluid inside the output end body 231 through the straight-through sleeve 234.

[0031] The solenoid valve group 300 is arranged on one side of the frame 100. The solenoid valve group 300 includes four solenoid valves 310. The solenoid valves 310 can be remotely controlled by signals. The four solenoid valves 310 are divided into lower solenoid valve groups V1 and V2 and upper solenoid valve groups V2 and V3. The lower solenoid valve group and the upper solenoid valve group control the conduction and closing of the guide pipe 220. The truth table of the solenoid valves V1, V2, V3 and V4 during normal operation is as described in Table 1.

[0032] Table 1:

[0033]

[0034]

[0035] The solenoid valve values ​​1 and 0 in the table represent whether the solenoid valve is normal, and the ESD function values ​​1 and 0 represent whether the valve control module can complete the ESD function. The ESD function specifically refers to the emergency shutdown of the valve, that is, whether the valve can be effectively shut down by controlling the solenoid valve 310.

[0036] The isolation valve group 400 is arranged on one side of the solenoid valve group 300. The isolation valve group 400 includes four isolation valves 410. The isolation valve 410 includes a handle 411, a locking pin 412, a locking plate 413 and an isolation valve body 410. The handle 411 is used to control the working state of the isolation valve body 410. The locking pin and the locking plate 413 are used to cooperate to lock the isolation valve body 410. The isolation valve body 410 is used to control the conduction and closing of the guide tube 220. The isolation valve 410 corresponds to the solenoid valve 310 one by one. That is, each solenoid valve 310 has an isolation valve 410 working together with it. The default working state of the solenoid valve 310 is a normally closed valve, and the default working state of the isolation valve 410 is a normally open valve. The staff pulls out the locking pin 412 and pulls the handle 411 outward to adjust the working state of the isolation valve 410. The isolation valve 410 temporarily replaces the solenoid valve 310 to cut off the conduction of the guide pipe 220 at that location, so that the damaged solenoid valve 310 can be replaced in time when the fluid system is operating, effectively improving the service life and reliability of the valve control module.

[0037] The status indicator group 500 includes four status indicators 510, and the four status indicators 510 are respectively used to indicate the on-off status of the four solenoid valves 310. The status indicators 510 can be set according to actual needs. In the default state, the on-off status of the solenoid valve 310 can be indicated by setting a status indicator light. For example, a green light indicates that the solenoid valve 310 is turned on, and a red light indicates that the solenoid valve 310 is turned off. The status indicator 510 is set on the frame 100, and the status indicator 510 can be fixedly connected to the frame 100 by a fixed connection method such as welding, or can be detachably connected to the frame 100 by a screw connection or a plug-in connection. The connection method is selected according to actual needs.

[0038] Working principle: The control module of the invention is installed at the desired control position through the frame 100, and the fluid is received by the fluid pipe 200 and the fluid is conducted to the solenoid valve group 300 and the isolation valve group 400 and the output end 230. In the default working state, the connection between the fluid pipe 200 and the output end 230 is closed, and the solenoid valve group 300 controls the conduction and closing of the guide pipe 220. The solenoid valve group 300 includes four solenoid valves 310 to prevent the failure of a single solenoid valve 310 from affecting the normal use of the valve control module. The working state of the solenoid valve 310 is monitored by the status indicator 510. When the solenoid valve 310 fails, the status indicator 510 is used to monitor the working state of the solenoid valve 310. When a fault occurs, the staff pulls out the locking pin 412 of the isolation valve 410 and controls the isolation valve 410 through the handle 411 to temporarily replace the solenoid valve 310 to control the on and off of the guide tube 220, so that the damaged solenoid valve 310 can be replaced in time when the fluid system is operating, so as to effectively improve the reliability of the valve control module. When an emergency occurs and the fluid in the valve control module needs to be released, the connection between the fluid tube 200 and the output end 230 can be opened, and the fluid entering the control module of the invention can be directly output from the output end 230, so as to avoid the problem of damage to the valve control module due to fluid blockage.

Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
