The pressure relief device 2' is composed of a movable valve body 21, a spring 2, a positioning cylinder 23, an outer casing 24 and a screw 25. The movable valve body 21; the spring force to the spring 22 can block the air hole in' and the positioning cylinder 23 can control the position of the inner and outer movements of the parent screw 25 to change the pressure state supplied to the movable valve body 21. In the conventional structure, when the internal pressure of the control valve seat 1 is generated, the pressure can automatically push open the movable valve body 21, and the air is discharged through the pressure release pipe 12 through the air hole lu; however, the conventional structure is slightly equivalent in internal pressure. During the spring force of the spring 22, the movable valve body 21 tends to open and close intermittently, and intermittently open and close, causing continuous vibration, resonance or collision noise of the movable valve body 21 with respect to the air vent. The noise generated by this critical interval of pressure relief has disadvantages such as plaguing patients and affecting rest and recuperation for the medical environment. In view of this, the inventors believe that an improvement scheme should be proposed to eliminate the noise generated by the (four) pressure valve when the pressure is in the critical section of the opening and closing or when the movable valve body is closed. In order to solve the problem of the operation of the case, the company has been able to improve the existing operation of the pressure valve in the critical section, so that the pressure relief valve can achieve a silent use. SUMMARY OF THE INVENTION The present invention has the main purpose of providing a pressure relief device, which has a right yang and a damping structure, which can eliminate the venting. The pressure 201241337 is slightly different from the jitter, resonance or intermittent collision noise generated when the ejection pressure is in the critical interval. In order to achieve the above object, the specific means of the present invention is that: by the pressure relief damping structure, the pressure relief action can be reduced due to the sensitivity, and the hysteresis of the opening and closing can be generated to eliminate the jitter, resonance or intermittent collision of the critical interval. sound. The specific content of the present invention is that the damper structure is composed of a movable valve plug, a spring and a positioning cylinder. The movable valve plug has a rounded plug body at one end, at least two clamping pieces are arranged at the rear end of the plug body, and a gap is formed between each clamping piece, and the clamping piece is slightly elastic. The end edge is provided with a rib, and a bevel is formed at the end of the rib. The spring is a conventional continuous ring structure, and the middle portion of the structure is wider than the two ends to form a relatively tapered shape. The positioning cylinder comprises a first column member having different diameters and a curved ring portion at a junction of the first main member and the second column member. By arranging the movable valve plug 'spring and the positioning cylinder in sequence and placing it in the pressure regulating tube body with air holes, the outer end of the positioning rod is fixed. The spring will provide an elastic force to the movable valve plug, and the movable valve plug Located at the inner edge of the air hole: the two clamping pieces of the movable valve plug cooperate with the two ribs to slightly clamp the first column member; when the plug body of the movable valve plug is pressed by the external force of the air hole, and the pressure is greater than the spring force of the spring, the movable room The plug will force the spring to contract and the active valve plug will leave the air vent and create a pressure relief condition. «Outside the stomata. (5) The force is less than the spring force of the spring. The magazine will force the movable valve plug to close the air hole. At this time, the pressure relief will be stopped. If the external pressure of the air hole is slightly equivalent to the spring force, that is, the live 5 201241337 dynamic valve plug and air hole are at In the critical section of opening and closing, when the state is closed at the time of opening and closing, the damping effect of the first column member clamped by the clamping piece and the rib of the feature of the present invention can effectively slow down the closing speed of the movable valve plug relative to the air hole. Sensitivity, by making the hysteresis of the active valve plug close to the air hole closing, is the quiet advantage of no jitter, resonance or collision noise. L. The mode of the "no noise relief pressure damping device" of the present invention And the effect produced by the method, together with the drawings, a preferred embodiment of the present invention is described in detail below. Please refer to the fifth, sixth and seventh figures, "I-noise line pressure damping device" The (4) device 3 is composed of a movable valve plug, a spring 32 and a positioning cylinder 33. The movable valve plug 3 has a rounded plug body 311 at one end, and the rear end of the plug body 311 is provided. At least two clamping pieces 312' are each clamped Between the sheets 312, there is a =313' and the clamping M 312 is slightly elastic. The inner edge of the missing piece 312 has a rib 3121, and the rib ribs*shan occupies a slanted surface 3122; the spring 32 , is a conventional continuous ring-shaped hollow structure, on the periphery of the clamping piece 312, the diameter of the middle section of the elastic π έ 槐 槐 饥 饥 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 The first column member 331 and the first column member 333 having different diameters are included, and the first column member mi disk 丄卞1 intersects with the second column member 333 to connect the dummy curved ring portion 332; - the column splicing portion w is passed through the spring 32 to engage between the moxibustion pieces 312 of the movable valve plug 31. The body 3 = / ^ _ ' will be ^ 31, the material 32 and the positioning cylinder 33 is arranged in series and placed in the pressure regulating pipe body 11 with the negative rolling hole U1% 6 201241337. The positioning cylinder 33 is externally fixed α·g π ^ and the outer end is fixed, and the spring 32 will provide a bullet. At the same time, the two clamping pieces 312 cooperate with the two ribs 3121 to generate a clamping pressure to the first column member 33 as the movable valve plug, and the plug body 311 is pressed to the external force and the pressure is greater than the spring 32, 6 that is When the pressure is released, the movable valve plug 31 contracts the pressure spring 32, and at the same time, the u ^ movable valve plug 31 is released from the air hole 111' to form a pressure relief state. When the external pressure of the air hole ill is smaller than the spring force of the spring 32, the spring will Forcing the movable plug 31 to close the air hole m, and at this time, the stop (four) state, if the external pressure of the air hole 111 is slightly equal to the elastic force of the spring 32, that is, the movable valve plug 31 and the air hole lu are in the critical interval of opening and closing, opening In the closed state, the damping effect of the first column member 331 (such as the seventh figure) is clamped by the clamping rib 31 of the clamping piece 31 of the present invention, which can effectively reduce the closing of the movable valve plug 31 relative to the air hole lu. Speed and sensitivity, by the hysteresis and delay of closing the movable valve plug 31 with respect to the air hole ,, that is, the frequency and speed at which the movable valve plug 31 is closed relative to the air hole 111 during the critical interval can be eliminated; thus, the activity The number of times the valve plug 31 collides with the air hole 111 is lowered, and the speed at which the movable valve plug 31 is closed relative to the air hole 1丨丨 due to the damping action is slowed down, and the action is soft and gentle, and there is no jitter or resonance. Like, you can achieve the quiet advantage of no collision noise. In the past, all the pressure relief valves were in the critical range of jitter, resonance or collision noise when the pressure relief was opened and closed. There has never been a solution. It can even be said that no one has ever faced this problem. The inventor developed the damping of this case. The sound structure effectively eliminates this annoying voice. The process of this case has indeed brought the quietness of the pressure relief 7 201241337 device to a higher level, and achieved a perfect state. In summary, the "noise-free pressure relief damping device" of the present invention, in accordance with the provisions of Article 44 of the current Patent Law, does not violate Articles 21 to 14, and Article 26 of the same law. Article 30, paragraph 1, item 2, article 21, article 32 or item 49, paragraph 4, etc. The case was indeed exploited in the industry and was not seen in the publication or publicly used before the application, and was not known to the public.
