Description

Technical Field

[0001] The utility model belongs to the technical field of intelligent control valves, in particular to an intelligent control valve for a liquefied petroleum gas cylinder. Background Art

[0002] Intelligent control valves control fluid flow by receiving signals from the control system, such as 4-20mA current signals and 0-10V voltage signals, converting them into valve opening signals through a signal converter. The valve is then driven by an actuator to drive the valve. Intelligent control valves utilize a combination of sensors, valve actuators, and control modules. Sensor signals transmit commands to the control module, which then activates the valve actuator.

[0003] During the use of existing intelligent control valves, the electronic components inside the control valves need to be regularly inspected and repaired;

[0004] However, most of the intelligent control valves currently on the market adopt an integrated design, and the connections between their internal components are tighter, which increases the difficulty of disassembly and maintenance. Utility Model Content

[0010] As a preferred embodiment of the above technical solution, a sealing ring is fixedly installed inside the connecting pipe, and the inner ring of the sealing ring is fixedly sleeved on the bottom end of the connecting pipe.

[0011] As a preferred embodiment of the above technical solution, the sealing ring is made of rubber material.

[0012] The beneficial effects of the utility model are:

[0013] (1) The utility model uses a screw arranged inside the connecting pipe to rotate the bolt to drive the block inside the alarm housing to move toward the slot. When the block is engaged with the slot, the alarm housing is fixedly installed on the top of the connecting pipe. The operation is simple, and the alarm housing can be easily disassembled and installed, which is convenient for staff to inspect and repair the components inside the alarm housing.

[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0023] Example 1

[0024] The utility model provides a valve for intelligent control of liquefied petroleum gas cylinders, such as Figures 1 to 6 As shown, it includes a valve body 1, a connecting pipe 2 is fixedly installed inside the valve body 1, an alarm housing 3 is provided at the top of the connecting pipe 2, the alarm housing 3 contains electronic components such as a gas detector, a gas alarm controller and a connecting cable, and the normal alarm function of the liquefied gas alarm is ensured by the cooperation of these components. A limit plate 5 is symmetrically fixedly installed at the bottom end of the inner wall of the alarm housing 3, and a screw 4 is rotatably connected to the position between the two limit plates 5 inside the alarm housing 3. The screw 4 passes through the connecting pipe 2 and is rotatably connected to the inside of the connecting pipe 2. The screw 4 The outer surface is located between the two limit plates 5 and is connected with a block 6 through a thread. Both sides of the block 6 are in contact with the surfaces of the two limit plates 5. A slot 7 is provided inside the alarm housing 3 at the position corresponding to the bottom end of the block 6. By rotating the screw 4 and cooperating with the groove opened inside the limit plate 5, the rotation of the screw 4 is converted into a linear motion of the screw 4. The rotation of the screw 4 is controlled to move the block 6 into the inside of the slot 7, thereby fixing the alarm housing 3. The design is simple, which facilitates the disassembly and installation of the alarm housing 3 and reduces the disassembly strength of maintenance personnel.

[0025] like Figure 2 、 Figure 4 and Figure 5 The outer surface of the rotating rod 10 is fixedly sleeved with a gear 11, and a clip 12 is slidably mounted on the inside of the alarm housing 3. By rotating the rotating rod 10, the excess fixing belt 9 is wrapped around the outer surface of the rotating rod 10, and the fixing belt 9 is in a taut state, thereby making the inner wall of the fixing belt 9 fit the outer surface of the valve body 1, and then sliding the clip 12 to move it to the tooth groove position of the gear 11, thereby fixing the position of the rotating rod 10 and preventing the rotating rod 10 from rotating, thereby achieving the effect of secondary fixation of the alarm housing 3, and avoiding the problem that the valve body 1 is working in an oil fume environment for a long time and the fixing components inside the alarm housing 3 are aging and rusting, thereby reducing its fixing effect.

[0026] like Figure 1 and Figure 6As shown, a sealing ring 13 is fixedly installed inside the connecting pipe 2, and the inner ring of the sealing ring 13 is fixedly sleeved on the bottom end of the connecting pipe 2. The sealing ring 13 is made of rubber material. Through the setting of the sealing ring 13, the leakage of liquefied gas between the connecting pipe 2 and the alarm housing 3 can be effectively prevented, thereby ensuring the sealing of the pipeline and reducing the occurrence of safety hazards.

[0027] Working principle: When using the device, rotate the screw 4, and under the action of the two limit plates 5, the screw 4 rotates and drives the block 6 to move in the direction close to the slot 7, and then the block 6 moves to the inside of the slot 7, thereby fixing the alarm housing 3 to the top of the connecting pipe 2. The design is reasonable and the operation is simple, which facilitates the disassembly of the alarm housing 3 and reduces the difficulty for the staff to disassemble the alarm housing 3. Then, rotate the rotating rod 10 so that the excess part of the fixing belt 9 is wrapped around the outer surface of the rotating rod 10. Rotate the rotating rod 10 so that the inner wall of the fixing belt 9 fits the outer surface of the valve body 1, and the fixing belt 9 is in a taut state. Then push the card strip 12 so that the card strip 12 moves to the inside of the tooth groove of the gear 11, so that the gear 11 will not drive the rotating rod 10 to rotate. At this time, the secondary fixation of the alarm housing 3 is achieved, thereby improving the stability of the alarm housing 3.

[0028] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
