Description
技术领域 technical field
本实用新型涉及一种碗形垫圈，属于密封技术领域。 The utility model relates to a bowl-shaped washer, which belongs to the technical field of sealing.
背景技术 Background technique
碗形垫圈是气杆的重要承压部件，安装于活塞杆底部，用于对气杆内高压气体进行施压获得弹力。由于碗形垫圈随活塞杆不断地做往复运动，且处于高压工作环境，因此对碗形垫圈的密封性和强度有着较高的要求。现有的碗形垫圈结构简单，密封性差，在长期往复运动后容易出现磨损失效；且现有的碗形垫圈为纯橡胶件，当活塞杆受压不均衡时，容易出现偏载，导致气杆行程不稳定，存在不足。 The bowl washer is an important pressure-bearing part of the gas rod, installed at the bottom of the piston rod, and is used to pressurize the high-pressure gas in the gas rod to obtain elasticity. Since the bowl-shaped gasket continuously reciprocates with the piston rod and is in a high-pressure working environment, there are high requirements for the sealing and strength of the bowl-shaped gasket. The existing bowl-shaped gasket has simple structure and poor sealing performance, and is prone to wear and failure after long-term reciprocating motion; and the existing bowl-shaped gasket is made of pure rubber. The rod stroke is unstable and there are deficiencies.
