Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of valves, in particular to a highly wear-resistant titanium alloy ball valve. Background Technique
[0002] A ball valve has an operation of rotating 90 degrees. The outer contour of its valve core is a sphere, and there is a circular through hole or passage passing through its axis. The ball valve is mainly used to cut off, distribute and change the flow direction of the medium in the pipeline. It can be tightly closed only with a 90-degree rotation operation and a very small torque.
[0003] In the prior art, when the ball valve is used, solid particles will enter. There is no filter component inside the ball valve, and it is unable to block the sundries existing in the transported liquid. The sundries are transported along with the liquid. Over time, the inner wall of the valve body and the contact part with the valve ball will be worn, and the sealing effect of the ball valve will become worse. In order to improve the service life of the valve, the commonly used wear-resistant ball valves on the market generally use valve balls and valve stems made of wear-resistant materials to improve the wear resistance of the valve. However, the existing wear-resistant spheres and valve stems are solid cast spheres, which not only use more raw materials and have high production costs, but also need to be replaced as a whole when worn, and the replacement cost is relatively high. Summary of the Utility Model
[0004] The purpose of the utility model is a highly wear-resistant titanium alloy ball valve, which is provided with a filter component to block and filter sundries, and is provided with a hollow structure valve ball and a detachable valve stem, which reduces the cost and also has high wear resistance.
[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions: a highly wear-resistant titanium alloy ball valve, including a valve body, a valve cover, a valve stem and a valve ball. Import channels and export channels are respectively arranged on both sides of the valve body. The valve ball is made of titanium alloy. The import channel is provided with a filter component. The valve ball is of a hollow structure and is provided with an annular cavity. First support rings are arranged on both sides inside the cavity. Both ends of the first support ring respectively abut against the top wall and the bottom wall of the cavity. A second support ring with a V-shaped cross-section is arranged in the middle inside the cavity. Both ends of the second support ring respectively abut against the top wall and the bottom wall of the cavity. The valve stem includes a detachable socket and a connecting rod. A first slot is arranged at the top of the valve ball. The socket is made of titanium alloy and is provided with a first plug block at the bottom that is circumferentially connected and adapted to the first slot. A second slot is arranged at the top of the socket. The bottom of the connecting rod is provided with a second plug block that is circumferentially connected and adapted to the second slot. The upper end of the connecting rod passes through the valve cover. A hand wheel is connected to the upper end of the connecting rod.
[0006] By adopting the above technical solution, a filtering component is provided to block particulate impurities, reduce the contact with the inner wall of the valve body and the valve ball, thereby reducing wear and extending the service life. The valve ball is made of titanium alloy with excellent wear resistance, and the valve ball is set as a hollow structure, reducing the cost and replacement cost. The first support ring and the two ends of the cavity form a triangular structure, and the second support ring and the bottom wall of the cavity form a triangular structure, thereby providing better support for the cavity and increasing the structural strength of the valve ball. The valve stem is divided into a plug joint and a connecting rod. The plug joint rotates in cooperation with the valve ball. The plug joint is made of titanium alloy with excellent wear resistance, reducing the cost. When the valve stem needs to be replaced, it is not necessary to replace the whole, only the corresponding parts need to be replaced, which also reduces the replacement cost.
[0007] As a further optimization of the present utility model, a ceramic wear-resistant sheet is provided on the inner wall of the valve cover.
[0008] By adopting the above technical solution, the ceramic wear-resistant sheet has good wear resistance, thereby reducing the wear of the valve stem on the valve cover and extending the service life of the ball valve.
[0009] As a further optimization of the present utility model, the shapes of the first slot and the second slot are both polygons.
[0010] By adopting the above technical solution, circumferential linkage between the first slot and the first plug and circumferential linkage between the second slot and the second plug are achieved.
[0011] As a further optimization of the present utility model, the filtering component is detachably connected to the inlet passage.
[0012] By adopting the above technical solution, the filtering component can be disassembled, facilitating the removal of deposited impurity particles, and the maintenance and replacement of the filtering component.
[0013] As a further optimization of the present utility model, the filtering component includes a support ring and a filter net arranged in the support ring. An annular groove is formed on the inner wall of the inlet passage, internal threads are provided on the side wall of the annular groove, and external threads are provided on the support ring and are threadedly connected to the annular groove.
