Description

Technical Field

[0001] The utility model belongs to the technical field of gas pressure reducing equipment, and particularly relates to an intelligent pressure and flow integrated secondary pressure reducing box for medical gas. Background Technique

[0002] At present, the secondary pressure reducing box is an essential medical device in hospitals. It is used to perform secondary pressure reduction on the conveyed gas to ensure that the pressure of the reduced gas meets the usage standards. At the same time, the secondary pressure reducing box is also used to open or cut off the pipeline channel in this area, facilitating the maintenance of pipelines and equipment.

[0003] The existing secondary pressure reducing box has the following defects: The gas transmission pipeline is pre-constructed and laid, and the distance between it and the wall is fixed. When the secondary pressure reducing box is installed, the distance between the box body and the wall is also fixed, and it is impossible to match the distance between the gas transmission pipeline and the wall, resulting in difficulty in accurately docking the pipeline joint on the box body with the gas transmission pipeline. A reducing joint needs to be used, which not only increases the cost but also reduces the construction difficulty. Summary of the Invention

[0004] The purpose of the utility model is to solve the above-mentioned technical problems existing in the prior art, and provide an intelligent pressure and flow integrated secondary pressure reducing box for medical gas, with novel structure, which can flexibly adjust the distance between the box body and the wall to match the actual distance between the gas transmission pipeline and the wall, facilitating the accurate docking of the gas transmission pipeline and the threaded joint, without the need to configure an additional reducing joint to increase the cost, and also reducing the construction difficulty of the secondary pressure reducing box.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] An intelligent pressure and flow integrated secondary pressure reducing box for medical gas, comprising: a box body, on which an air inlet pipe and an air outlet pipe are respectively arranged; characterized in that: an installation plate is arranged on the back of the box body, the installation plate is connected with a U-shaped bracket for installation on the wall, a limiting groove is arranged on the U-shaped bracket, a positioning pin is arranged on the installation plate, a first nut and a second nut are screwed on the positioning pin, the positioning pin passes through the limiting groove, and the U-shaped bracket is clamped by the cooperation of the first nut and the second nut. This secondary pressure reducing box has a novel structure, can flexibly adjust the distance between the box body and the wall to match the actual distance between the gas transmission pipeline and the wall, facilitating the accurate docking of the gas transmission pipeline and the threaded joint, without the need to configure an additional reducing joint to increase the cost, and also reducing the construction difficulty of the secondary pressure reducing box.

[0007] Furthermore, the limiting groove includes a first hole and a second hole, the first hole is located above the second hole and is connected to the second hole, the cross-sectional diameter of the first hole is larger than the cross-sectional diameter of the second hole, the first hole corresponds to the second nut, and the second hole corresponds to the positioning pin. During installation, first pass the second nut through the first hole, then lower the box body so that the positioning pin enters the second hole, and then rotate the first nut until the first nut sticks to the U-shaped bracket, the first nut cooperates with the second nut to clamp the U-shaped bracket, and the first nut and the second nut cannot pass through the second hole, thereby limiting the free sliding of the positioning pin forward and backward, close contact, large friction, and the box body cannot move upward freely, so that the box body is limited and fixed on the U-shaped bracket, which is stable and reliable.

[0008] Furthermore, the mounting plate is provided with a limiting screw hole which is screwed with the positioning pin. The positioning pin is fixed reliably and can be used at any time after installation, which is flexible and convenient.

[0009] Furthermore, a microprocessor is provided in the box body, and a touch screen is provided on the box cover of the box body, and the touch screen is electrically connected to the microprocessor. Maintenance personnel can set the parameter standard value of oxygen at the alarm point through the touch screen, and the modified data is saved by the microprocessor. The touch screen can also display various parameters of oxygen in the gas supply process in real time, which is clear at a glance.

[0010] Furthermore, an intake pressure gauge is connected to the intake pipe, and an outlet pressure gauge is connected to the outlet pipe, and the intake pressure gauge and the outlet pressure gauge are electrically connected to the microprocessor respectively. The oxygen pressure values in the intake pipe and the outlet pipe are displayed through the touch screen, which is intuitive and clear.

[0011] Furthermore, a flow sensor is connected to the air outlet pipe, and the flow sensor is electrically connected to the microprocessor. The flow sensor can detect the flow of oxygen in the air outlet pipe, and display the oxygen flow value through the touch screen, thereby improving the safety of gas supply.

[0012] Furthermore, the box is provided with an RS-485 communication interface, and the microprocessor is electrically connected to the RS-485 communication interface. The real-time parameters of oxygen are transmitted to the host of the central monitoring system for remote monitoring, which reduces the difficulty of management.

[0013] Furthermore, an audible and visual alarm is provided on the box body, and the audible and visual alarm is electrically connected to the microprocessor. When the real-time parameters of oxygen exceed or fall below the standard values of oxygen parameters set by the system, the microprocessor activates the audible and visual alarm, and the audible and visual alarm sends out an audible and visual alarm to notify the surrounding personnel, so as to solve the fault or problem in time, with intelligent early warning and high safety.

[0014] Furthermore, a pressure relief safety valve is connected to the air outlet pipe. When the pressure of oxygen in the air outlet pipe is too high, the pressure relief safety valve automatically opens to perform pressure relief operation, thereby improving safety.

[0015] Further, threaded connectors are provided on both the intake pipe and the outlet pipe, facilitating connection to the gas transmission pipeline.

[0016] Further, flanges are provided at both ends of the U-shaped bracket, enhancing the structural strength of the U-shaped bracket and making it not easily deformable; fixing through holes are provided on the flanges, facilitating the insertion of screws to fix the U-shaped bracket on the wall surface, improving the convenience of installation.

[0017] Due to the adoption of the above technical solutions, the present utility model has the following beneficial effects:

[0018] When installing the box body, first pass the second nut through the first hole position, then lower the box body so that the positioning pin enters the second hole position, and then rotate the first nut until the first nut abuts against the U-shaped bracket. The first nut and the second nut cooperate to clamp the U-shaped bracket. Neither the first nut nor the second nut can pass through the second hole position, thereby restricting the free sliding of the positioning pin back and forth. They are in close contact with a large frictional force, and the box body cannot move upward freely, making the box body limited and fixed on the U-shaped bracket, which is stable and reliable; the first nut and the second nut can be rotated to change the positions of the first nut and the second nut on the positioning pin, thereby changing the length of the positioning pin passing through the U-shaped bracket, and then changing the distance between the box body and the wall surface to match the actual distance between the gas transmission pipeline and the wall surface, facilitating the accurate docking of the gas transmission pipeline and the threaded connector, without the need to configure additional adapters to increase costs, and also reducing the construction difficulty of the secondary pressure reducing box.
