Description

说明书 自平衡式自补偿密封球阀  Instructions Self-balancing self-compensating sealed ball valve
技术领域  Technical field
[1] 本发明创造涉及一种中压或者高压领域使用的大通径球阀。  [1] The present invention relates to a large-diameter ball valve for use in the medium or high pressure field.
背景技术  Background technique
[2] 目前， 各种类型的球阀， 其进出口均直接与阀体腔相通， 而且压力流体直接作 用在球阀芯上， 通过 90度旋转实现开启和关闭。 当对压力较高， 通径较大的球 阀开启或关闭吋， 由于流体压力作用， 会有很大力使球阀芯压向阀座或驱动轴 ， 因此造成操纵扭矩很大， 在摩擦力的作用下使密封部位破坏速度加快， 以上 原因， 是影响了大通径， 高压力球阀的发展的主要原因。  [2] At present, various types of ball valves have their inlet and outlet directly connected to the valve body cavity, and the pressure fluid is directly applied to the ball valve core to open and close by 90 degree rotation. When the ball valve with a high pressure and a large diameter is opened or closed, due to the fluid pressure, there is a great force to press the ball valve core against the valve seat or the drive shaft, thus causing a large steering torque under the action of friction. The above-mentioned reasons are the main reasons that affect the development of large-diameter and high-pressure ball valves.
对发明的公开  Disclosure of invention
技术问题  technical problem
[3] 本发明创造的目的是提供一种自平衡式自补偿密封球阀， 该球阀通过平衡腔使 所控制的压力流体同吋并对称的作用在球阀芯的两侧， 实现压力自平衡。 同吋 通过一种对球阀芯自补偿密封方式， 实现球阀的轻便开启与关闭， 并且能够设 计制造出比现有球阀压力更高通径更大的新型球阀。  [3] The object of the invention is to provide a self-balancing self-compensating sealing ball valve, which realizes pressure self-balancing by balancing the controlled pressure fluids on both sides of the ball valve core through the balance chamber. Simultaneously, the ball valve is self-compensating and sealing, which realizes the light opening and closing of the ball valve, and can be designed to produce a new ball valve with a higher diameter than the existing ball valve.
技术解决方案  Technical solution
[4] 一种自平衡式自补偿密封球阀， 其组成包括： 阀体及其阀盖， 安装在阀体中的 球阀阀芯， 所述的阀体和所述的阀盖中具有与阀入口相通的对称的平衡腔， 所 述的平衡腔与所述的阀芯中的 T  [4] A self-balancing self-compensating sealed ball valve, the composition comprising: a valve body and a valve cover thereof, a ball valve spool installed in the valve body, the valve body and the valve cover having a valve inlet a symmetrical balance chamber, the balance chamber and the T in the valve core
形孔对应， 所述的阀芯和所述的阀体之间装有密封活塞。  Corresponding to the shape hole, a sealing piston is arranged between the valve core and the valve body.
[5] 所述的自平衡式自补偿密封球阀， 所述的平衡腔中对称装有背压弹簧， 所述的 背压弹簧顶在所述的密封活塞上。 [5] The self-balancing self-compensating sealed ball valve, wherein the balance chamber is symmetrically equipped with a back pressure spring, and the back pressure spring is mounted on the sealing piston.
[6] 所述的自平衡式自补偿密封球阀， 所述的 T [6] The self-balancing self-compensating sealing ball valve, the T
形孔的第三端通过环形平衡腔与所述的阀出口相通。  The third end of the shaped bore communicates with the valve outlet through an annular balance chamber.
有益效果  Beneficial effect
[7] 通过平衡腔使得两个自补偿密封活塞上同吋受到等压力流体作用， 从而实现了 球阀芯的压力自平衡。 同吋， 由压向球阀芯的自补偿密封活塞和具有启闭通道 的球阀芯的不同对应位置实现球阀的启闭功能， 因此， 该阀操纵力矩可极大减 少， 使得在相同压力等级下， 通径范围可得到很大扩展； 适于中高压力流体的 通断控制。 [7] The balance chamber is used to make the two self-compensating sealing pistons act on the same pressure fluid, thus achieving The pressure of the ball valve core is self-balancing. At the same time, the ball valve opening and closing function is realized by different corresponding positions of the self-compensating sealing piston pressed to the ball valve core and the ball valve core having the opening and closing passage, so that the valve operating torque can be greatly reduced, so that under the same pressure level, The diameter range can be greatly expanded; it is suitable for on-off control of medium and high pressure fluids.
[8] 当压力流体由阀体进口， 通过所述的阀体和所述的阀盖中具有与阀入口相通的 对称的平衡腔分别对称进入并作用在球阀芯 6两侧和两个自补偿密封活塞 9 上吋， 阀芯处于压力平衡状态， 所以可以轻易的旋闭阀芯， 实现氐扭矩下的开 闭。 减少或者避免了流体压力下的机械磨损， 能大幅度的提高阀门寿命， 减轻 旋转压力。  [8] When the pressure fluid is imported from the valve body, the symmetrical balance chambers in the valve body and the valve cover having a symmetrical inlet with the valve inlet respectively enter and act symmetrically on both sides of the ball valve core 6 and two self-compensation The upper part of the sealing piston 9 is in a pressure-balanced state, so that the valve core can be easily closed and closed to achieve opening and closing under the torque. Reduces or avoids mechanical wear under fluid pressure, which greatly increases valve life and reduces rotational pressure.
[9] 阀芯关闭后， 即使有反向压力， 由于阀芯处于环形平衡腔内， 平衡了侧向压力 [9] After the spool is closed, even if there is reverse pressure, the lateral pressure is balanced because the spool is in the annular balance chamber.
， 同样能够实现氐扭矩下的开启和关闭， 避免压力不平衡造成的机械磨损和阀 门泄漏问题。 It also enables opening and closing under 氐 torque to avoid mechanical wear and valve leakage caused by pressure imbalance.
[10] 由于自补偿密封活塞 9与球阀芯 6  [10] Due to self-compensating sealing piston 9 and ball valve plug 6
接触一侧的面积小于另一侧面积， 所以使其一直压向球阀芯 6  The area on the contact side is smaller than the area on the other side, so that it is pressed against the ball valve core 6
确保密封， 而且磨损后可自动补偿。 背压弹簧 8  Ensuring a seal and automatically compensating after wear. Back pressure spring 8
提供一个预紧力参与密封； 因球阀芯 6的 T  Provide a preload force to participate in the seal; due to the ball valve core 6 T
形孔包括直通孔和与其相通的开启通道 15， 所以当驱动轴在 90  The shaped hole includes a through hole and an opening passage 15 communicating therewith, so when the drive shaft is at 90
度旋转吋， 通过对 T形孔中通孔位置的选择即可实现开启和关闭。  Rotate the 吋 and turn it on and off by selecting the position of the through hole in the T-shaped hole.
