Description

Technical Field

[0001] The utility model relates to the technical field of pressure regulators, in particular to a gas pressure regulator with an explosion-proof alarm function. Background Art

[0002] When the pressure regulator is working, it is necessary to equip both the inlet and outlet with pressure gauges. If the air pressure is too high, the pressure gauge will display it to prevent natural gas leakage. The operator's inspection of the natural gas pressure regulating equipment is staged. After a certain period of operation, the pressure data of the inlet and outlet will be checked. During the waiting period for the inspection, if the air pressure is too high, it may have caused a series of problems such as natural gas leakage. Therefore, the pressure gauge cannot detect the air pressure in real time and cannot detect problems in time. Utility Model Content

Therefore, the directional terms used are used to illustrate and understand the present invention, rather than to limit the present invention.

[0014] like Figure 1-3 A gas pressure regulator with explosion-proof alarm function shown in the figure includes a body 1 and a detection component installed on the body 1, a pressure relief pipe 2 is installed at the air inlet end of the body 1, and a pressure relief pipe 2 is installed at the pressure regulating end, the detection component includes a functional tube 4, both ends of the functional tube 4 are installed with alarm lights 5, a partition 6 is fixedly installed on the inner wall of the functional tube 4, the partition 6 separates the functional tube 4 into two chambers, and the end of a single chamber is installed with an alarm light 5, the pressure relief pipe 2 is connected to one of the chamber pipes of the functional tube 4, and the pressure relief pipe 2 is connected to the other chamber pipe of the functional tube 4.

[0015] A limit ring 9 is fixedly installed at the bottom of the alarm light 5, and the outer wall of the limit ring 9 is threadedly connected to the inner wall of the functional tube 4. A contact switch is installed at the bottom of the alarm light 5. A movable plate 7 is provided on the side of the partition 6 facing the alarm light 5, and the connection points where the pressure relief pipe 1 2 and the pressure relief pipe 2 3 are connected to the functional tube 4 are located between the movable plate 7 and the partition 6, and a spring 8 is fixedly installed between the movable plate 7 and the alarm light 5.

[0016] A contact rod 10 is fixedly mounted on the outer wall of one movable plate 7, and a contact rod 2 11 is fixedly mounted on the outer wall of another set of movable plates 7. The movable plate 7 with the contact rod 10 mounted is installed in the chamber where the functional tube 4 is connected to the pressure relief tube 1 2, and the movable plate 7 with the contact rod 2 11 mounted is installed in the chamber where the functional tube 4 is connected to the pressure relief tube 2 3. The contact rod 10 and the contact rod 2 11 are both mounted on the side of the movable plate 7 facing the warning light 5, and the length of the contact rod 10 is less than the length of the contact rod 2 11.

[0017] Embodiment: Natural gas enters from the air inlet end of the body 1 and is sent out from the air outlet end after pressure regulation. The air inlet pressure at the air inlet end is relatively high. Therefore, in order to prevent the air pressure from being too high and causing the natural gas to leak, a pressure relief pipe 1 2 is installed at the air inlet end so that part of the natural gas can be diverted from the inside of the pressure relief pipe 1 2, reducing the air inlet pressure of the body 1 and preventing the natural gas from leaking at the air inlet end. The pressure relief pipe 2 3 is installed at the pressure regulating end of the body 1. After the pressure regulation is completed, the natural gas is discharged from the outlet end. In order to prevent the discharge pressure from being too high and causing leakage, part of the natural gas is diverted from the inside of the pressure relief pipe 2 3. The natural gas at the air inlet end and the pressure regulating end will enter the two chambers of the functional pipe 4. If the air pressure inside the pressure relief pipe 2 3 or the pressure relief pipe 1 2 is too high, the movable plate 7 inside the functional pipe 4 will be pushed up by the air pressure, and the spring 8 will be compressed and deformed. The contact rod 1 10 or the contact rod 2 11 contacts the contact switch at the bottom of the alarm light 5. The alarm light 5 is powered on and lit.

[0018] Since the pressure inside the pressure relief pipe 2 3 is lower than that inside the pressure relief pipe 1 2, the requirements for air pressure detection are different. The length of the contact rod 2 11 is greater than that of the contact rod 10, which shortens the distance from the contact rod 2 11 to the contact switch at the bottom of the alarm light 5. This improves the accuracy of air pressure detection. When the air pressure is too high, the alarm light 5 will be lit, and the control end will also receive an electrical signal indicating that the alarm light 5 is lit. The two alarm lights 5 at both ends of the functional pipe 4 represent the air intake end and the pressure regulating end, respectively. The operator can also quickly determine which end has a problem based on the position of the alarm light 5 that is lit.

[0019] It should be noted that the parts not covered in the present invention are the same as the prior art or can be implemented by the prior art; the various drives in the present invention can be implemented by corresponding power structures such as cylinders, oil cylinders, electric cylinders, motors, etc. in combination with connecting rods, guide rods, etc., and are not limited to the description in the specification and the structures in the drawings.

[0020] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
