Description

Technical Field

[0001] This application relates to the field of gas transmission technology, and in particular to a gas pressure regulating component. Background Technology

[0002] With the widespread application of natural gas in industrial and residential sectors, the demand for gas pressure regulation is increasing daily. A safe and stable supply of natural gas is crucial for the normal operation of various equipment and the safety of users' lives and property. Therefore, reliable gas pressure regulating components are needed to achieve precise pressure regulation and timely shut-off of gas supply in abnormal situations.

[0003] In existing gas pressure regulating technologies, pressure regulators, typically composed of regulating caps, springs, pressure diaphragms, connecting rods, and levers, are used to regulate and cut off gas pipeline pressure. When cutting off gas, the regulator still employs a complex pressure regulating structure. On one hand, the cutting-off device operates relatively slowly, failing to effectively cut off the gas and increasing safety risks. On the other hand, the internal components such as connecting rods, levers, and springs are closely related to the regulator's performance. Because the cutting-off action lacks buffering, each action impacts the internal levers and connecting rods, causing component dimensional shifts or performance degradation, resulting in a decrease in regulator performance. Utility Model Content

[0004] Therefore, it is necessary to provide a gas pressure regulating component that can accurately regulate pressure and immediately cut off pressure.

[0005] To solve the above-mentioned technical problems, this application provides the following technical solution:

[0006] This application relates to the field of gas transmission technology, and in particular to a gas pressure regulating component.

[0007] A gas pressure regulating component, comprising:

[0008] A pressure regulator has an air inlet channel, an air outlet channel, and a valve port, wherein the air inlet channel and the air outlet channel are connected through the valve port;

[0009] A shut-off device is installed on the pressure regulator. The shut-off device includes an opening and closing element that can reciprocate relative to the valve port edge to control the opening / closing of the valve port.

[0010] Understandably, by setting the valve port and the reciprocating motion of the opening and closing element in the shut-off device relative to the edge of the valve port, when it is necessary to cut off the gas pipeline, the valve port can be closed simply by the opening and closing element blocking the valve port, thereby cutting off the gas pipeline. This design can cut off the gas supply in time when needed, improving the safety of gas use. On the other hand, the separate shut-off device avoids the problem of component size displacement or performance degradation caused by the impact when shutting off the gas supply using a pressure regulator.

[0011] In one embodiment, the opening and closing element is disposed in the area where the air outlet channel is located.

[0012] In one embodiment, the diameter of the valve port is greater than or equal to the minimum diameter of the air outlet passage.

[0013] In one embodiment, the valve port edge is arc-shaped;

[0014] When the opening and closing element closes the valve port, the opening and closing element can undergo elastic deformation under the pushing force of the valve port edge.

[0015] In one embodiment, the cutting device is threadedly connected to the voltage regulator.

[0016] Understandably, the cutting device is connected to the voltage regulator via threads. This connection method is secure, easy to install and disassemble, and facilitates maintenance and replacement when components in the cutting device and voltage regulator malfunction.

[0017] In one embodiment, the gas pressure regulating assembly further includes a seal, which is at least partially disposed between the pressure regulator and the shut-off device for assembling and sealing the pressure regulator and the shut-off device.

[0018] Understandably, by setting up a seal, the gap between the pressure regulator and the shut-off device is sealed, preventing gas from overflowing through the gap, effectively preventing gas leakage, improving the sealing performance between the pressure regulator and the shut-off device, and ensuring the safe operation of the gas pressure regulating component.

[0019] In one embodiment, the seal has a plurality of sealing portions disposed between the pressure regulator and the cut-off device;

[0020] Each of the sealing parts is deformable under pressure and is used to assemble and seal the pressure regulator and the cutting device.

[0021] In one embodiment, the cutting device further includes an elastic element that abuts against the opening / closing element in a pre-compressed manner, and the opening / closing element is movable toward the edge of the valve port under the push of the elastic element to close the valve port.

[0022] Understandably, by setting up an elastic element and pressing it against the opening and closing element in a pre-compressed manner, when it is necessary to cut off the gas pipeline, the opening and closing element moves rapidly toward the edge of the valve port under the push of the elastic element, closing the valve port. In this way, it can be ensured that the opening and closing element closes the valve port quickly, improving the response speed of the cutting-off device.

[0023] In one embodiment, the cutting device further includes a telescopic rod and a locking member, the locking member being able to abut against the telescopic rod for limiting and locking the telescopic rod;

[0024] The opening and closing component is installed on one end of the telescopic rod.

[0025] In one embodiment, the voltage regulator includes an upper housing, a lower housing, and a voltage regulating mechanism, wherein the upper housing is mounted on the lower housing so that the upper housing and the lower housing enclose a receiving cavity;

[0026] The pressure regulating mechanism is disposed in the accommodating cavity and is used to control the channel diameter of the air intake channel;

[0027] The air inlet channel, the valve port, and the air outlet channel are all located on the upper housing.

[0028] Compared with the prior art, the gas pressure regulating component, by setting the valve port and the reciprocating motion of the opening and closing element in the shut-off device relative to the edge of the valve port, can close the valve port simply by blocking the opening and closing element when it is necessary to cut off the gas pipeline. This design can cut off the gas supply in time when needed, improving the safety of gas use. On the other hand, the additional shut-off device avoids the problem of component size displacement or performance degradation caused by the impact when shutting off the gas supply using a pressure regulator.

[0041] Please see Figures 1 to 4 This application provides a gas pressure regulating assembly 100, which includes a pressure regulator 10 and a shut-off device 20. The pressure regulator 10 has an inlet channel 11, an outlet channel 12 and a valve port 13. The inlet channel 11 and the outlet channel 12 are connected through the valve port 13. The shut-off device 20 is installed on the pressure regulator 10 and includes an opening and closing member 21. The opening and closing member 21 can reciprocate relative to the valve port edge 131 on the valve port 13 to control the opening / closing of the valve port 13. Thus, by setting the valve port 13 and the reciprocating movement of the opening and closing element 21 in the shut-off device 20 relative to the valve port edge 131, when it is necessary to cut off the gas pipeline, the valve port 13 can be closed simply by the opening and closing element 21 blocking the valve port 13, thereby cutting off the gas pipeline. This design can cut off the gas supply in time when needed, improving the safety of gas use. On the other hand, the additional shut-off device 20 avoids the problem of component size displacement or performance degradation caused by the impact when the pressure regulator 10 is used to cut off the gas supply.

[0042] like Figure 1 and Figure 3 As shown, the pressure regulator 10 includes an upper housing 14, a lower housing 15, and a pressure regulating mechanism 16. The upper housing 14 is mounted on the lower housing 15 so that the upper housing 14 and the lower housing 15 enclose a receiving cavity 17. The pressure regulating mechanism 16 is disposed in the receiving cavity 17 and is used to control the channel diameter of the air intake channel 11. The air intake channel 11, the valve port 13, and the air outlet channel 12 are all disposed on the upper housing 14.

[0043] Here, the upper housing 14 and the lower housing 15 are detachably connected. Specifically, the upper housing 14 and the lower housing 15 can be connected by methods such as threaded connection or flange connection. Such connection methods are common in related technologies and will not be described in detail here.

[0044] In this embodiment, the pressure regulating mechanism 16 includes a top block 161, a lever 162, a connecting rod 163, a diaphragm 164, an adjusting cap 165, and a spring 166. The right end of the lever 162 is provided with a top block 161 that abuts against the air intake channel 11. The connecting rod 163 connects to the left end of the lever 162. The diaphragm 164 is sleeved on the lower end of the connecting rod 163. The spring 166 is located below the diaphragm 164. The adjusting cap 165 is connected to the lower housing 15. The pressure regulating mechanism 16 can adjust the position of the top block 161 by pushing the spring 166 through the adjusting cap 165, thereby adjusting the pressure of the air intake channel 11.

[0045] like Figure 3 and Figure 4 As shown, the diameter of valve port 13 is greater than or equal to the minimum orifice diameter of gas outlet channel 12. By setting valve port 13, the shut-off device 20 can be activated quickly. At this time, the diameter of valve port 13 is greater than or equal to the minimum orifice diameter of gas outlet channel 12, which can ensure smooth flow of gas at valve port 13.

[0046] In one embodiment, the opening / closing element 21 is disposed in the area where the air outlet passage 12 is located. This allows the opening / closing element 21 to be closer to the valve port edge 131 on the valve port 13, thereby further improving the timeliness of sealing the valve port 13 with the opening / closing element 21 when the shut-off device 20 is activated.

[0047] Furthermore, the valve port edge 131 is arc-shaped; when the opening and closing element 21 closes the valve port 13, the opening and closing element 21 can undergo elastic deformation under the pushing force of the valve port edge 131. In this way, when the opening and closing element 21 closes the valve port 13, the arc-shaped valve port edge 131 and the elastic deformation of the opening and closing element 21 cooperate to better seal the valve port 13, prevent gas leakage caused by incomplete sealing of the valve port 13, and improve the sealing performance of the gas pressure regulating assembly 100 for the valve port 13.

[0048] like Figures 1 to 3 As shown, the cutting device 20 is connected to the pressure regulator 10 by a thread. This connection method is secure, easy to install and disassemble, and facilitates maintenance and replacement when components in the cutting device 20 and the pressure regulator 10 malfunction.

[0049] Furthermore, the shut-off device 20 also includes an elastic element 22, which abuts against the opening and closing element 21 in a pre-compressed manner. The opening and closing element 21 can move towards the valve port edge 131 under the pushing force of the elastic element 22 to close the valve port 13. Thus, by providing the elastic element 22 and pre-compressing it against the opening and closing element 21, when it is necessary to shut off the gas pipeline, the opening and closing element 21 moves rapidly towards the valve port edge 131 under the pushing force of the elastic element 22 to close the valve port 13. This ensures that the opening and closing element 21 quickly closes the valve port 13, improving the response speed of the shut-off device 20.

[0050] Preferably, the elastic element 22 is a spring.

[0051] In one embodiment, the cutting device 20 further includes a telescopic rod 23 and a locking member 24. The locking member 24 can abut against and limit the telescopic rod 23 to lock it. The opening / closing member 21 is mounted on one end of the telescopic rod 23. Specifically, the locking member 24 can be configured as an electromagnet assembly. The locking of the telescopic rod 23 is achieved by the abutment and limiting action between the movable part of the electromagnet assembly and the telescopic rod 23. It should be noted that the movement direction of the movable part of the electromagnet assembly is perpendicular to the movement direction of the telescopic rod 23.

[0052] The operation of the cutting device 20 is as follows:

[0053] When the cutting device 20 opens the valve port 13 via the opening and closing member 21, the opening and closing member 21 is in the retracted state, the locking member 24 abuts against the telescopic rod 23 to limit its movement, and the telescopic rod 23 is locked. At this time, the elastic member 22 is in the pre-compressed state. When the cutting device 20 opens the valve port 13 via the opening and closing member 21, by controlling the displacement of the telescopic rod 23, the abutment limit between the locking member 24 and the telescopic rod 23 is released. Under the push of the elastic member 22, the opening and closing member 21 moves toward the edge 131 of the valve port, and the opening and closing member 21 is in the extended state.

[0054] like Figure 4 As shown, the gas pressure regulating assembly 100 also includes a seal 30, which is at least partially disposed between the pressure regulator 10 and the shut-off device 20, for sealing the pressure regulator 10 and the shut-off device 20 during assembly. It can be understood that by providing the seal 30, the gap between the pressure regulator 10 and the shut-off device 20 is sealed, preventing gas from overflowing through the gap, effectively preventing gas leakage, improving the sealing performance between the pressure regulator 10 and the shut-off device 20, and ensuring the safe operation of the gas pressure regulating assembly 100.

[0055] Furthermore, the seal 30 has multiple sealing portions 31 disposed between the pressure regulator 10 and the shut-off device 20; wherein each of the multiple sealing portions 31 is deformable under pressure, and is used to assemble and seal the pressure regulator 10 and the shut-off device 20 respectively. By providing multiple sealing portions 31 to block the easily leaking parts between the pressure regulator 10 and the shut-off device 20, the problem of gas overflowing from the shut-off device 20 is effectively solved.

[0056] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
