Abstract

The utility model discloses an utilize bellows sealing's ball valve, including valve body, disk seat, spheroid, valve rod, adorn the disk seat cover admittedly at the flange end of valve body, the disk seat overlaps the bottom extension board of bottom setting and the contact of disk seat bottom surface, is the recess form between disk seat and disk seat overlap, and the bellows setting is in the recess, and the one end of bellows is welded with the disk seat, and the other end and the disk seat cover of bellows weld. Application method: through the sealed elasticity that fills up the adjustment bellows, when the spheroid rotated, the disk seat pressurized promoted the bellows, reduced the frictional force of sealed face.

Description

利用波纹管密封的球阀Ball valves sealed with bellows

技术领域 technical field

本实用新型涉及一种利用波纹管密封的球阀。 The utility model relates to a ball valve sealed by a bellows.

背景技术 Background technique

球阀的开关过程中，球体始终与阀座紧贴，接触表面存在确保密封的密封力；特别是高压阀门密封力大，摩擦剧烈，不仅驱动力矩大、成本高、能耗高，而且密封面使用寿命短。 During the opening and closing process of the ball valve, the ball is always in close contact with the valve seat, and there is a sealing force on the contact surface to ensure the seal; especially for high-pressure valves, the sealing force is large and the friction is severe, not only the driving torque is large, the cost is high, and the energy consumption is high, but also the sealing surface uses Short life.

发明内容 Contents of the invention

本实用新型的目的在于提供一种结构合理，开关过程摩擦小、使用寿命长的利用波纹管密封的球阀。 The purpose of the utility model is to provide a ball valve sealed with bellows with reasonable structure, low friction in the switching process and long service life.

本实用新型的技术解决方案是： The technical solution of the utility model is:

一种利用波纹管密封的球阀，包括阀体、阀座、球体、阀杆，其特征是：在阀体的法兰端固装阀座套，阀座套底部设置与阀座底面接触的底部延伸板，阀座与阀座套之间呈凹槽形式，波纹管设置在凹槽中，波纹管的一端与阀座焊接，波纹管的另一端与阀座套焊接。 A ball valve sealed by a bellows, including a valve body, a valve seat, a ball, and a valve stem, characterized in that: a valve seat sleeve is fixed on the flange end of the valve body, and the bottom of the valve seat sleeve is provided with a bottom that contacts the bottom surface of the valve seat The extension plate is in the form of a groove between the valve seat and the valve seat sleeve, the bellows is arranged in the groove, one end of the bellows is welded to the valve seat, and the other end of the bellows is welded to the valve seat sleeve.

阀座套通过螺钉和密封垫与阀体固定。 The valve seat sleeve is fixed with the valve body by screws and gaskets.

波纹管与阀座、阀座套的上端焊接。 The bellows is welded to the upper end of the valve seat and the valve seat sleeve.

使用方法：通过密封垫调整波纹管的弹力；球体转动时，阀座受压推动波纹管，减小密封面的摩擦力。 How to use: Adjust the elasticity of the bellows through the gasket; when the ball rotates, the valve seat is pressed to push the bellows, reducing the friction on the sealing surface.

本实用新型结构合理，开关过程摩擦小、使用寿命长。 The utility model has the advantages of reasonable structure, small friction in the switching process and long service life.

附图说明 Description of drawings

下面结合附图和实施例对本实用新型作进一步说明。 Below in conjunction with accompanying drawing and embodiment the utility model is further described.
