技术领域technical field
本实用新型属于燃气输送设备技术领域，尤其涉及一种自平衡高压放散阀。The utility model belongs to the technical field of gas conveying equipment, in particular to a self-balancing high-pressure relief valve.
背景技术Background technique
燃气放散阀是一种使用在燃气调压设备上的燃气安全装置，具有超压放散稳定压力的功能。当燃气调压器出口压力升高,超过放散压力设定值时，放散阀阀口打开，气体排出，保证安全用气，来满足用户使用要求。当前使用的燃气放散阀，其结构包括带有进气口、出气口的阀体，阀体内设置有阀口、膜片，膜片上面设置有托盘，托盘上面设置有调节弹簧和调节螺母，膜片与阀杆顶部连接，阀杆底部设置有与阀口相匹配的阀垫。燃气调压器出口压力低于放散压力设定值时，膜片上面的调节弹簧使阀垫关闭阀口。当燃气压力超过放散压力设定值，推动阀垫使阀杆带动膜片上行压缩调节弹簧，阀垫与阀口间出现间隙，燃气经由阀垫与阀口间的间隙由出气口排出，实施放散。在放散结束后，燃气放散阀的调节弹簧伸展，推动阀杆使阀垫关闭阀口。阀垫关闭阀口时，调节弹簧的伸展力直接作用给阀垫，阀垫容易受损，对放散阀效果造成影响。The gas release valve is a gas safety device used on gas pressure regulating equipment, which has the function of releasing overpressure and stabilizing the pressure. When the outlet pressure of the gas pressure regulator rises and exceeds the set value of the relief pressure, the relief valve opens and the gas is discharged to ensure safe gas use to meet the user's requirements. The gas release valve currently used has a structure including a valve body with an air inlet and an air outlet, a valve port and a diaphragm are arranged in the valve body, a tray is arranged on the diaphragm, an adjusting spring and an adjusting nut are arranged on the tray, and The piece is connected with the top of the valve stem, and the bottom of the valve stem is provided with a valve pad matching the valve port. When the outlet pressure of the gas pressure regulator is lower than the set value of the relief pressure, the adjustment spring on the diaphragm will make the valve pad close the valve port. When the gas pressure exceeds the setting value of the release pressure, push the valve pad so that the valve stem drives the diaphragm upward to compress the adjustment spring, and a gap appears between the valve pad and the valve port, and the gas is discharged from the gas outlet through the gap between the valve pad and the valve port, and the gas is released. . After the release is over, the regulating spring of the gas release valve stretches, pushing the valve stem to make the valve pad close the valve port. When the valve pad closes the valve port, the stretching force of the adjusting spring acts directly on the valve pad, and the valve pad is easily damaged, which affects the effect of the relief valve.

本实用新型所提供的自平衡高压放散阀，燃气调压器出口压力低于放散压力设定值时，调节弹簧伸展力下压调节弹簧座、放散活门套、放散活门，阀垫关闭阀口。当燃气压力超过放散压力设定值，燃气推动阀垫，放散活门、放散活门套、调节弹簧座上移压缩调节弹簧，阀垫与阀口间出现间隙，燃气经由阀垫与阀口间的间隙由出气口排出，实施放散。在放散结束后，燃气压力减小，活门弹簧、调节弹簧伸展，调节弹簧座、放散活门套、放散活门下行，在活门弹簧作用下，放散活门向下伸出放散活门套先与阀门接触，然后调节弹簧再带动调节弹簧座、放散活门套向下压缩活门弹簧，使放散活门缩入放散活门套，调节弹簧对放散活门施加压力，阀垫关闭阀口。这样，阀体内设置有放散活门，能够起到平衡入口压力对阀垫造成的冲击，以及上部调节弹簧压力过大，对阀垫造成的伤害。在放散结束后，通过活门弹簧的缓冲作用，使得调节弹簧的伸展力不直接作用给阀垫，阀垫受损状况大大减小，保证放散阀使用效果。在正常情况下，阀垫关闭阀口时，活门弹簧在对阀垫向下用力的同时，活门弹簧也给调节弹簧一个上弹力，减小了调节弹簧的设计压力，减轻了调节弹簧压力过大对阀垫的伤害，提高了阀垫的使用寿命，调节范围进一步加强，放散压力大大提高，灵敏度更高。放散阀在进口压力高的情况下，调节弹簧很小的作用力，就可以使阀垫关闭阀口。活门锁杆设置有里外通透的气道，防止放散活门与放散活门套之间出现抽真空。放散活门与放散活门套之间、放散活门套与放散调节筒之间、放散调节筒与阀体之间分别设置有密封圈，确保密封，保证放散阀使用效果。放散活门套的顶部设置有凸台，调节弹簧座设置有与凸台相匹配的中心孔，放散活门套与调节弹簧座套接在一起，使用效果好。In the self-balancing high-pressure relief valve provided by the utility model, when the outlet pressure of the gas pressure regulator is lower than the set value of the relief pressure, the stretching force of the adjustment spring is pressed down to adjust the spring seat, the relief valve sleeve, and the relief valve, and the valve pad closes the valve port. When the gas pressure exceeds the setting value of the release pressure, the gas pushes the valve pad, the release valve, the release valve sleeve, and the adjustment spring seat move up to compress the adjustment spring, and there is a gap between the valve pad and the valve port, and the gas passes through the gap between the valve pad and the valve port. Discharged from the air outlet for release. After the release is completed, the gas pressure decreases, the valve spring and the adjustment spring stretch, the adjustment spring seat, the release valve sleeve, and the release valve go down. Under the action of the valve spring, the release valve extends downwards. The adjustment spring drives the adjustment spring seat and the release valve cover to compress the valve spring downwards, so that the release valve is retracted into the release valve cover, the adjustment spring exerts pressure on the release valve, and the valve pad closes the valve port. In this way, a release valve is arranged in the valve body, which can balance the impact of the inlet pressure on the valve pad, and the damage to the valve pad caused by the excessive pressure of the upper adjusting spring. After the release is over, through the buffering effect of the valve spring, the stretching force of the adjusting spring does not directly act on the valve pad, the damage of the valve pad is greatly reduced, and the use effect of the release valve is guaranteed. Under normal circumstances, when the valve pad closes the valve port, the valve spring exerts downward force on the valve pad, and at the same time, the valve spring also gives an upward force to the adjustment spring, which reduces the design pressure of the adjustment spring and reduces the excessive pressure of the adjustment spring. The damage to the valve pad improves the service life of the valve pad, further strengthens the adjustment range, greatly improves the release pressure, and has higher sensitivity. When the inlet pressure of the relief valve is high, the small force of the adjustment spring can make the valve pad close the valve port.
