[0002] During the daily operation of specialty gas equipment, various abnormal factors often lead to equipment control system malfunctions or power outages. In many cases, the corresponding process equipment still requires the use of specific specialty gases. Therefore, forced gas delivery is necessary for process equipment (such as gas-driven valves).

[0003] Currently, forced opening is typically performed directly on the solenoid valve body, connecting to an external high-pressure gas source to forcibly supply gas to the process equipment. However, such forced opening requires specialized tools and expertise, and the related equipment needs to be assembled manually, making the construction difficult and the operation cumbersome. Moreover, manual operation carries the risk of accidental opening. Utility Model Content

[0017] The present invention will now be described in detail with reference to specific embodiments. It should be emphasized that the following description is merely exemplary and is not intended to limit the scope and application of the present invention.

[0018] It should be noted that, unless otherwise expressly specified and limited, the terms "center," "longitudinal," "lateral," "upper," "lower," "vertical," "horizontal," "inner," and "outer," etc., used in this specification to indicate the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this utility model. The terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features; thus, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature; "multiple" means two or more; and "and / or" includes any and all combinations of one or more related listed items. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0019] This utility model provides a forced supply device for special gas equipment. This device is connected between the gas supply source and the pneumatic actuator, and under normal circumstances, it does not affect the gas supply from the gas source to the pneumatic actuator. It is further connected to a high-pressure gas source, and when the gas supply source cannot supply gas, a forced-opening function is activated to force the high-pressure gas source to supply gas to the pneumatic actuator.

[0020] like Figures 1 to 4 As shown, the special gas equipment forced supply device includes: device body 10, multiple air inlet ports 20, multiple air outlet ports 30, forced opening knob 40, and forced opening gas source port 50.

[0021] The device body 10 is roughly square in shape and contains multiple sets of gas pipelines. The gas inlet 20 is located at the bottom of the device body 10 and is used to connect to the gas supply source; it is the gas inlet under normal circumstances.

[0022] An air outlet 30 is also located at the bottom of the device body 10, used to connect to the gas interface of the pneumatic actuator and supply gas to the pneumatic actuator. An air inlet 20 is connected to an air inlet 30 through a separate gas pipeline to form a continuous air supply pipeline.

[0023] The forced-on knob 40 is located at the top of the device body and is used to control the forced-on function of the forced-on device to be turned on or off. The user can switch between turning the forced-on function on and off by turning the forced-on knob 40 to different angles.

[0024] Preferably, such as Figure 3 As shown, an instruction label 70 is also provided on the top of the device body. The instruction label 70 indicates whether the forced-opening function is on or off, corresponding to different rotation angles of the forced-opening knob 40. Through this instruction label 70, users can intuitively and conveniently confirm whether the special gas equipment forced-opening device is in the state of having the forced-opening function on.

[0025] A forced-opening air source interface 50 is located on the first side of the device body for connecting to an external high-pressure air source. A gas valve is installed between the forced-opening air source interface 50 and multiple internal gas pipelines. This gas valve is controlled by a forced-opening knob 40, so that when the forced-opening knob 40 is turned to the open position, the gas valve opens, allowing high-pressure gas to enter the gas pipeline and continue to supply forced air to the pneumatic actuator through the outlet interface 30.

[0026] In some embodiments, such as Figure 4 As shown, the forced-supply device also includes an exhaust muffler 60.

[0027] The exhaust muffler 60 is located at the bottom of the device body and serves as the exhaust outlet. When the forced-supply device switches from the forced-open function to the closed function, the high-pressure gas in the gas pipeline is slowly discharged through the exhaust muffler 60.

[0028] The exhaust muffler 60 may have an exhaust outlet with a porous structure, which slowly releases high-pressure gas during depressurization to avoid sharp whistling noise caused by rapid release of high-pressure gas, thus affecting the working environment and operational safety.

[0029] For details, please continue reading. Figure 4 Multiple air intake ports 20 are arranged in a row along a first straight line at the bottom of the device body. Multiple air outlet ports 30 and exhaust mufflers 60 are arranged in a row along a second straight line parallel to the first straight line.

[0030] In addition, multiple exhaust ports 30 are symmetrically arranged along the exhaust muffler 60, which is positioned in the middle. The specific number of intake ports 20 and exhaust ports 30 can be set according to actual needs, for example... Figure 4 The four shown.

[0031] In some embodiments, such as Figure 2 As shown, the forced supply device also includes: a pneumatic indicator light 80.

[0032] The pneumatic indicator light 80 is located on the second side of the device body and is used to further display and indicate whether the forced opening function has been activated.

[0033] The second side is the other side of the device body 10 opposite to the first side. For example, when the forced opening function is turned on, the pneumatic indicator light 80 is lit, and when the forced opening function is turned off, the pneumatic indicator light 80 is turned off.

[0034] In some embodiments, please continue reading Figure 2 The forced gas supply device also includes a pressure sensor 90. This pressure sensor 90 is also located on the first side, adjacent to the forced gas supply interface 50, and is used to detect the gas pressure within the gas pipeline. The pressure sensor 90 can be installed... Figure 5 As shown, the detection node marked with D is used to detect the air pressure at that node.

[0035] The following combination Figure 5 Describe in detail the specific operating principle of the forced supply device for this special gas equipment. For example... Figure 5 As shown, the four air intake ports 20 are labeled IN1, IN2, IN3, and IN4, respectively, and the four air outlet ports 30 are labeled OUT1, OUT2, OUT3, and OUT4, respectively. The following description uses air intake port IN1 and air outlet port OUT1 as examples:

[0036] A first check valve structure is provided between the air intake port IN1 and the corresponding air outlet port OUT1. The air outlet port OUT1 is also connected to the connecting pipeline, forming a connection node C1. A second check valve structure is also formed between the connection node C1 and the air outlet port OUT1.

[0037] Under normal conditions, the gas entering through the intake port IN1 can flow smoothly out through the corresponding outlet port OUT1, and is prevented from flowing to the connection node C1 by the second one-way valve structure. At this time, the gas valve controlled by the forced-open knob 40 is in the closed state and is not connected to the forced-open gas source port 50.

[0038] When the intake port IN1 cannot supply gas, the gas valve is opened when the forced-open knob 40 is turned (at this time, A is connected to point P). The forced-open gas source port 50 is connected to the connecting pipeline. The gas input from the forced-open gas source port 50 passes through the connecting node C1 and the second one-way valve structure, and can be output from the corresponding outlet port OUT1. However, due to the restriction of the first one-way valve structure, it will not flow to the intake port IN1.

[0039] The special gas equipment forced supply device provided in this embodiment can be conveniently and quickly installed between the gas supply pipelines of the gas equipment, and the forced gas supply function can be easily activated by turning the forced opening knob. The overall operation is convenient and simple.

[0040] The above description, in conjunction with specific / preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. Those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and all of these fall within the protection scope of the present invention.
