Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, specifically a novel pressure-reducing flow integrated box. Background Technology

[0002] The gas in medical gas pipelines is usually compressed by a compressor, and its pressure is typically high, making it unsuitable for direct use by patients and equipment. To ensure gas safety during medical procedures, the gas needs to be depressurized after reaching each floor, adjusting the pressure to a specific range before it can be used by patients and equipment. Each floor is also typically equipped with flow meters for various gases to monitor gas consumption on each floor.

[0003] Traditional pressure reducing boxes require a key to unlock, which can be inconvenient in emergencies as the key may be difficult to find. Secondly, the existing pressure reducing and flow monitoring equipment are separate units, resulting in complex piping layouts throughout the building, making management and maintenance difficult. Furthermore, the gas supply of existing pressure reducing equipment cannot be flexibly adjusted to respond promptly to changes in gas demand on different floors, causing further inconvenience to users. Utility Model Content

[0004] This utility model proposes a novel pressure-reducing flow integrated box, the purpose of which is to: solve the problem of not being able to open the box in time in an emergency; solve the problem of complex pipeline layout that is difficult to manage and maintain; and solve the problem of inconvenient gas supply adjustment.

[0005] The technical solution of this utility model is as follows:

[0006] A novel pressure-reducing and flow-regulating integrated box includes a housing, within which are an inlet pipe and an outlet pipe. A box cover is attached to the housing. The box also includes a lock. Its features include: an inlet pressure gauge installed on the inlet pipe, and an outlet pressure gauge and an electronic flow meter installed on the outlet pipe; two parallel pressure-reducing branches connected between the inlet and outlet pipes; a first T-shaped three-way ball valve connected to the outlet end of the inlet pipe, and a second T-shaped three-way ball valve connected to the inlet end of the outlet pipe; the inlet of the upper pressure-reducing branch is connected to the upper outlet of the first T-shaped three-way ball valve, and the outlet of the upper pressure-reducing branch is connected to the upper inlet of the second T-shaped three-way ball valve; the inlet of the lower pressure-reducing branch is connected to the lower outlet of the first T-shaped three-way ball valve, and the outlet of the lower pressure-reducing branch is connected to the upper inlet of the second T-shaped three-way ball valve; a pressure-reducing valve is installed on each pressure-reducing branch, and the gas, after pressure reduction, exits through the outlet pipe. The lock includes a base plate fixed to the lock body cover. Two lock arms are arranged parallel to each other and symmetrically between the base plate and the lock body cover. The lock arms are rotatably mounted on the base plate. A compression spring connects the two lock arms. A fixed bracket is connected to the inner wall of the housing at a position corresponding to the lock. The fixed bracket has an opening in the middle, and inclined plates are connected to the upper and lower ends of the opening, forming a flared mouth. A rectangular groove is opened at the right end of the lock arm. A sloping slide is provided in the groove, and a rectangular through hole is opened on the slide. The lock also includes a pull rod slidably connected to the base plate. A tension spring for pulling the pull rod to the left is fixed on the base plate. Two sets of second connecting rods are provided on the pull rod, each corresponding to one of the lock arms. The second connecting rods pass through the rectangular through hole on the lock arm and are connected to a second slider. The second slider is used to contact the slide. When the pull rod moves to the right, the second slider pushes the slide, causing the left end of the lock arm to rotate towards the center of the opening.

[0007] As a further improvement, a flow display is also provided on the cover of the housing, and a microcontroller including an A / D conversion circuit is also provided inside the housing. The electronic flow meter is electrically connected to the A / D conversion circuit, and the microcontroller is electrically connected to the flow display.

[0009] As a further improvement, the pull rod includes a handle, with a first connecting rod fixed at both the upper and lower ends of the handle, and a first slider that mates with the track groove fixed at the end of the first connecting rod opposite to the handle.

[0010] As a further improvement, a fixing block for securing the tension spring is also provided on the base plate.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] (1) By setting a lever-type lock on the box cover, the box cover can be opened without a key. When opening, it must be pulled to the right to avoid accidental operation. When closing, there is no need to pull the lever. The lever can be automatically reset under the action of the tension spring to achieve locking.

[0013] (2) By integrating the pressure reduction function and flow monitoring function into one, the pipeline structure is simplified, making management and maintenance easier;

[0021] The technical solution of this utility model will now be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0022] like Figure 1A novel pressure-reducing flow meter includes a housing 1, a cover 2, and internal piping. Two pressure gauges are installed inside the housing: an inlet pressure gauge 5 on the left and an outlet pressure gauge 6 on the right. Pressure values ​​can be easily read through observation holes on the cover 2. A flow monitoring area is provided between the observation holes of the two gauges to display the instantaneous and cumulative flow of the gas in the pipeline. The cover 2 has an observation window 4 with embedded tempered glass for observing the working status of the internal piping and valves. A lock 3 is installed on the left side of the housing for easy maintenance and inspection of the pressure-reducing flow meter.

[0023] like Figure 2 As shown, the internal piping of the housing 1 includes an intake pipe on the left and an outlet pipe on the right, with two parallel pressure-reducing branches connected between the intake and outlet pipes. The intake pipe is connected to an intake pressure gauge 5 to measure the pressure of the intake pipe, and the outlet pipe is connected to an outlet pressure gauge 6 and an electronic flow meter 9 to measure the pressure and flow rate of the outlet pipe. The outlet end of the inlet pipe is connected to a first T-shaped three-way ball valve 7, and the inlet end of the outlet pipe is connected to a second T-shaped three-way ball valve 10. The inlet of the upper pressure-reducing branch is connected to the upper outlet of the first T-shaped three-way ball valve 7, and the outlet of the upper pressure-reducing branch is connected to the upper inlet of the second T-shaped three-way ball valve 10. The inlet of the lower pressure-reducing branch is connected to the lower outlet of the first T-shaped three-way ball valve 7, and the outlet of the lower pressure-reducing branch is connected to the upper inlet of the second T-shaped three-way ball valve 10. Each pressure-reducing branch is equipped with a pressure-reducing valve 8, and the gas flows out through the outlet pipe after being depressurized.

[0024] A flow meter is installed within the pipeline flow monitoring area of ​​the housing cover 2. The housing integrates a microcontroller containing an A / D conversion circuit. The electronic flow meter 9 receives the analog electrical signal of the gas flow mass from the gas flow mass sensor via a digital display calculator and sends it to the A / D conversion circuit for digital signal conversion. Then, the processing module processes the gas mass flow data, converting it into the corresponding volumetric flow rate or mass flow rate under standard conditions. This processing module can calculate the instantaneous flow rate and cumulative flow rate, and transmit the calculation results to the flow meter for real-time display, thereby achieving real-time monitoring of the gas flow rate in the pipeline.

[0025] The new pressure reducing and flow integrated box has multiple working modes. The number of gas supply lines can be adjusted by adjusting the opening or closing of the T-shaped three-way ball valve to flexibly adapt to different gas demand conditions.

[0026] When only one pressure-reducing branch is needed for gas supply, the first T-shaped three-way ball valve 7 and the second T-shaped three-way ball valve 10 can be adjusted so that only one pressure-reducing branch is open, while the other pressure-reducing branch is closed. In this case, gas flows through the inlet pipe to the first T-shaped three-way ball valve 7, is depressurized by the single pressure-reducing branch, and then flows out through the outlet pipe via the second T-shaped three-way ball valve 10. The other pressure-reducing branch serves as a backup. When the gas supply from a single pressure-reducing branch cannot meet the demand, the first T-shaped three-way ball valve 7 and the second T-shaped three-way ball valve 10 can be adjusted so that both pressure-reducing branches are open. In this case, gas flows through the inlet pipe to the first T-shaped three-way ball valve 7, is depressurized by the two pressure-reducing branches, and then flows out through the outlet pipe via the second T-shaped three-way ball valve 10, thus increasing the gas supply capacity. When maintenance is required, the first T-shaped three-way ball valve 7 and the second T-shaped three-way ball valve 10 can be adjusted to close the corresponding pressure-reducing branch for repair or component replacement without affecting the normal operation of other parts of the system.

[0027] like Figure 3 , Figure 4 and Figure 5 As shown, the lock body 3 includes a base plate 3-1, which is fixed to the cover 2. Two locking arms 3-8 are arranged parallel to each other and are symmetrically positioned. The locking arms 3-8 are rotatably mounted on the base plate 3-1, and their rotation shaft 3-9 is fixed at the corresponding position on the base plate 3-1. The left end of the locking arm 3-8 is provided with an inclined surface, and the right end of the locking arm 3-8 is provided with a sloping slide 3-17. A rectangular through hole is also provided in the middle of the slide 3-17, penetrating the locking arm 3-8. A compression spring 3-4 and a fixing rod 3-5 are connected between the two locking arms 3-8 and are fixedly connected to the corresponding sides of the two locking arms 3-8 through the compression spring 3-4. The fixing rod 3-5 is fixed to the left side of the rotation shaft 3-9. The fixing rod 3-5 is flexible. A fixed bracket 3-2 is connected to the inner wall of the housing 1 at the corresponding position of the bottom plate 3-1. The fixed bracket 3-2 is fixed to the inner wall of the housing 1 by screws. The fixed bracket 3-2 has an opening in the middle, and inclined plates 3-3 are connected to the upper and lower ends of the opening respectively. The two inclined plates 3-3 form a flared mouth.

[0028] The lock body 3 also includes a pull rod 3-11, which includes a handle 3-12. The upper and lower ends of the handle 3-12 are respectively fixed with a first connecting rod 3-13. The end of the first connecting rod 3-13 facing away from the handle 3-12 is fixed with a first slider 3-15 that cooperates with the track groove 3-10. A second connecting rod 3-14 is connected to the first connecting rod 3-13. The second connecting rod corresponds one-to-one with the two locking arms. The second connecting rod 3-14 passes through a rectangular through hole and is connected to a second slider 3-16. The second slider 3-16 is in contact with the slide rail 3-17. When the pull rod 3-11 moves to the right, the second slider 3-16 pushes the slide rail 3-17 to make the left end of the locking arm 3-8 rotate toward the center of the opening.

[0029] The base plate 3-1 has a fixing block 3-7 fixedly connected to the base plate 3-1 at the middle position on both the upper and lower sides. The fixing block 3-7 and the first connecting rod 3-13 of the pull rod 3-11 are connected by a tension spring 3-6, which is used to pull the pull rod 3-11 to the left.

[0030] When it is necessary to open the box cover 2, pull the lever 3-11 to the right, so that the first slider 3-15 of the lever 3-11 slides to the right along the track groove 3-10 on the base plate 3-1. At this time, the tension spring 3-6 is stretched, the compression spring 3-4 is compressed, and the locking arm 3-8 rotates around the rotating shaft 3-9. The left ends of the locking arm 3-8 come together and disengage from the fixed bracket 3-2, pulling the box cover 2 outward. Then release the lever 3-11, the tension spring 3-6 returns to its original length, driving the lever 3-11 to reset, and the compression spring 3-4 is also released, driving the locking arm 3-8 to move in the opposite direction and return to the initial position, completing the unlocking. When it is necessary to close the locking cover 2, push the cover 2 inward. The left end of the locking arm 3-8 gradually moves closer under the action of the corresponding side inclined plate 3-3. After entering the opening of the fixed bracket 3-2, the locking arm 3-8 returns to the initial position under the action of the compression spring 3-4. At this time, the locking arm 3-8 is locked together with the fixed bracket 3-2, and the locking is completed.

[0031] It should be noted that, as will be apparent to those skilled in the art, this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. The scope of this utility model is defined by the claims rather than the foregoing description.
