New description: [New technical field] [0001] A differential pressure type quick release valve with a reverse stop function, especially in a high pressure gas storage tank, which is driven by a gas pressure difference and has a rapid release width. [Prior Art] [0002] Pressurized gas can provide power to drive pneumatic tools, or can be used to inflate objects, etc. Therefore, in general factories or steam and locomotive maintenance yards, air compressors are purchased to supply pressurized gas. Although in most cases, the high pressure gas supplied by the air compressor has sufficient pressure to inflate the object or drive the pneumatic tool. However, sometimes a large amount of instantaneous high-pressure pressurized gas is required to drive or push the inflated object. Conventional air compressors and output valves are not capable of providing an instantaneous large amount of pressurized gas at the time of output. For example, when a car is replaced with a new tire, it needs to be inflated from no gas at all. At this time, if the air compressor cannot provide a large amount of pressurized gas in an instant to open the tire in one breath, it will cause difficulty in charging the air into the tire. [0003] A general air compressor includes a pair of air pressurized pressurizing mechanisms, a high pressure gas storage tank for storing pressurized gas, and a gas release valve for controlling the high pressure gas storage tank to release pressurized gas. The conventional air compressor, such as the Republic of China Patent Certificate No. M376649, "Improved Structure of Air Compressor Check Valve", discloses a check valve of an air compressor, which includes a check valve having an air inlet and an air inlet end. Body, valve plug, spring, and a plug with an air inlet. The inlet end of the one-way valve body is formed with a groove for a spring and a valve plug insertion sleeve, and a plurality of air outlet holes penetrating the outlet end surface of the one-way valve body are formed at the inner end of the groove body, and The air outlet is in a state of being offset from the center of the pocket. The air compressor disclosed in the previous case further includes a piston cylinder, an air reservoir, and an external line connected between the plugging cylinder and the air cylinder of the M412280, which is connected to the live form No. A0101, and the aforementioned check valve can be It is installed between the piston cylinder and the external pipeline, or between the air reservoir and the external pipeline. [0004] Another prior art is the case of the "Integrated Structure of Air Compressor Operation Panel" of the Republic of China Patent Certificate No. M2 96924, which discloses that an air compressor is fixed to a gas storage tank through a base, and the pressure is applied. The components of the table, the pressure regulating valve, the quick pipe joint, the pipe joint of the air compressor, the safety valve and the pressure switch are pre-assembled and integrated on the same base, so that the user can simultaneously operate and monitor the side of the base. The pressure state of the air compressor. [0005] As can be seen from the above two previous cases, the general air compressor does not specifically design a wide door mechanism that instantaneously outputs a large amount of pressurized gas, which causes practical troubles. [New Content] [0006] Since the conventional structure does not specifically design a valve mechanism that instantaneously supplies a large amount of pressurized gas, it causes a problem in that the practical output is insufficient. Therefore, the present invention provides a relief valve structure that instantaneously outputs a large amount of pressurized gas through the improved structure and the installation position. [0007] The present invention is a differential pressure quick release valve having a reverse stop function, the quick release valve is installed in a high pressure gas storage tank, and one end of the quick release valve is connected to a control valve, and the other end is connected Gas line. The quick release valve comprises a hollow valve body, a differential pressure actuating piston housed in the hollow valve body, and an elastic body accommodated in the hollow valve body, wherein the hollow valve body comprises at least one air inlet opening and one air outlet An opening and a pressure relief hole communicating with the control valve, the differential pressure actuating piston having a blocking portion and an abutting surface, the elastic body abutting against the abutting surface to cause the glow plug form number A0101 page 4/16 pages close the outlet opening, and when the control valve acts to cause the pressure of the pressure relief hole to change, the pressure difference moves the differential pressure actuating piston to make the outlet opening unblocked and instantaneously output a large amount of pressurized gas. . According to the foregoing technical feature, the quick release valve is accommodated in the high pressure gas storage tank, and the differential pressure actuating piston is quickly moved through the pressure difference between the pressure relief hole and the intake opening to achieve an instantaneous output. The effect of the pressurized gas of the air volume. [Embodiment] [0009] The present invention is a differential pressure type quick release valve having a reverse function, and the technical features of the present invention will be described below in conjunction with the drawings. Referring to FIG. 1 and FIG. 2, FIG. 1 and FIG. 2 disclose a differential release valve 3 that is operated by a differential pressure difference, and the quick release valve 3 includes a hollow valve body 31'-mounted therein. The differential pressure actuating piston 32 in the hollow valve body 31 and the elastic body 33 in the hollow valve body 31, wherein the hollow valve body 31 includes at least one intake opening 311 and an outlet opening 31 〇, the hollow valve The inside of the body 31 has a space communicating with the intake opening 311 and the outlet opening 31 供 for gas to flow. Moreover, in order to adjust the air pressure in the hollow valve body 3, the intermediate valve body 31 should provide a path for attacking. Therefore, the hollow valve body μ reserves a connection opening 312, and the connection opening 312 can be separated from the connection. A connecting end 342 of the member 34 is engaged such that the connecting member 34 is detachably assembled to the hollow valve body 31. The connecting member 34 has a pressure releasing hole 341 communicating with the space inside the hollow valve body 31, and the control mechanism of the pressure relief or not is to be described in detail later. In order to facilitate the mounting of other components, the connecting end 342 and the connecting opening 312 can be loosened to disassemble the connecting member 34. A differential pressure actuating piston 32 and an elastic body 33 are further disposed in the hollow valve body 31, and the connector form number Α0101 5th page/total 6 pages M412280 34 is installed in the connection opening 312, The differential pressure actuating piston 32 and the elastic body 33 will be housed inside the hollow valve body 31. The differential pressure actuating piston 32 has a blocking portion 321, an abutting surface 322 and an inclined notch 323. The two ends of the elastic body 33 are respectively abutted between the connecting member 34 and the abutting surface 322. The elastomer 33 can be selected with a common spring as an embodiment, and due to the space in the spring, the differential pressure actuating piston 32 can be correspondingly provided with a positioning post 324 through the space in the center of the spring to assist in positioning. By the ejector of the elastic body 33, the differential pressure actuating piston 32 moves in the direction in which the elastic body 33 is pushed up without applying an external force, so that the blocking portion 321 closes the air outlet opening 310, and the inclined gap 323 The center of the differential pressure actuating piston 32 is inclined and retracted. When the blocking portion 321 closes the air outlet opening 310, the air inlet opening 311 is adjacent to the inclined notch 323, and air pressure is applied to the inclined notch 323. Further, in order to ensure airtightness between the differential pressure actuating piston 32 and the inner wall surface of the hollow valve body 31, at least one airtight rubber ring 35 is disposed around the differential pressure actuating piston 32. Referring to FIG. 3, the aforementioned quick release valve 3 is installed in a high pressure gas storage tank, and one end of the quick release valve 3 is connected to a control valve 5, and the other end is connected to an outlet gas line 6. The high pressure gas storage tank 2 has a gas storage space 2 connected to a high pressure gas source 1 which supplies pressurized gas into the gas storage space 20. The quick release valve 3 is located in the air storage space 20 of the high pressure gas storage tank 2, and the air inlet opening 311 allows the air storage space 20 to communicate with the internal space of the quick release valve 3. The high pressure gas storage tank 2 is further connected to an air outlet line 6, and the air outlet opening 310 of the quick release valve 3 is connected to the air outlet line 6. The pressure relief hole 341 of the quick release valve 3 is in communication with the control valve 5, and more specifically, the pressure relief hole 341 and the control valve 5 are connected with a form number A0101, page 6 / 16 pages, and a pressure relief tube. 4. The pressure relief hole 341 is communicated with the control valve 5 through the pressure relief tube 4. The actuation of the control valve 5 will control whether the air in the pressure relief tube 4 flows out through the control valve 5. Referring to FIG. 4-1 and FIG. 4-2 together, when the control valve 5 prohibits the air from flowing out, the air pressure between the pressure relief pipe 4, the pressure relief hole 341 and the differential pressure actuating piston 32 will be balanced. The elastomer 33 will push the differential pressure actuating piston 32 to close the outlet opening 310 (shown in Figure 4-1). When the control valve 5 is actuated to allow the air in the pressure relief tube 4 to pass, the instantaneous pressure imbalance will generate a pressure difference to move the differential pressure actuating piston 32. The blocking portion 321 is separated from the air outlet opening 310, so that the air outlet opening 310 is unblocked and instantaneous. Output a large amount of pressurized gas (as shown in Figure 4-2). Through the above structural features, the quick release valve 3 is accommodated in the high pressure gas storage tank 2, and the gas pressure in the high pressure gas storage tank 2 assists the quick release valve 3 to move the differential pressure actuating piston quickly. 32. The amount of air that releases pressurized gas is much larger than conventional manual control valves, providing instantaneous pressure superior to conventional structures.
