Description

Technical Field

[0001] This utility model relates to the field of stainless steel ball valve technology, and in particular to a stainless steel ball valve that is easy to connect. Background Technology

[0002] Stainless steel ball valves have a relatively simple structure, mainly composed of a valve body, valve cover, ball, valve stem, and sealing ring. Their working principle relies on rotating the valve core to open and close the valve. A simple 90-degree rotation easily allows fluid to flow freely or be blocked, making operation very simple and rapid, suitable for remote control. Due to the ball structure, in the fully open state, the valve body cavity is completely flat, providing a low-resistance, straight-through flow path for the medium. The fluid resistance coefficient is equal to that of a pipe section of the same length, resulting in a large flow rate and low flow resistance, effectively reducing energy consumption. Simultaneously, the sealing surfaces of the ball and valve seat are not easily eroded by the medium in the closed state. Furthermore, the widespread use of plastics as sealing materials ensures excellent sealing performance, allowing normal operation even in vacuum systems. In addition, the stainless steel ball valve material has excellent corrosion resistance and high-temperature resistance, adapting to various harsh working environments and suitable for controlling the flow of various types of fluids, including air, water, steam, and various corrosive media.

[0003] Existing stainless steel ball valves typically require multiple screws for connection, a cumbersome process that is time-consuming, labor-intensive, and demands specific operating space and tools. This further complicates installation in complex environments. Furthermore, their sealing performance is often inadequate, potentially leading to leaks and impacting performance and safety. To address these issues, this application proposes a stainless steel ball valve that facilitates easy connection. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a stainless steel ball valve that is easy to connect. By inserting the limiting block into the limiting groove, rotating the adjustment knob causes the bidirectional worm gear to rotate. The bidirectional worm gear rotates and meshes with the worm wheel, causing the worm wheel to rotate. The rotation of the worm wheel drives the connecting rod to rotate, and the rotation of the connecting rod drives the limiting block to rotate. The limiting block abuts against the inner wall of the limiting groove to fix the limiting block, thus connecting the two valves.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A stainless steel ball valve that is easy to connect includes a valve, a second connecting block fixedly connected to the left side of the outer wall of the valve, and a first connecting block fixedly connected to the right side of the outer wall of the valve. The right side of the first connecting block has four limiting grooves. The left limiting groove is connected to the left side of the right second connecting block through a limiting component to connect the two valves. The two valves abut against each other on their adjacent sides, and the adjacent sides of the inner walls of the two valves are connected by a sealing component to increase the sealing performance.

[0007] Furthermore, the limiting component includes a plurality of limiting blocks fixedly connected to the left side of the second connecting block, a limiting rotating block rotatably connected to the inner wall of the limiting block, the outer wall of the right limiting block being inserted into the inner wall of the left limiting groove, and the right side of the right limiting rotating block abutting against the right side of the inner wall of the left limiting groove.

[0008] Furthermore, a connecting rod is fixedly connected to the right end of the limiting rotating block, and a worm gear is fixedly connected to the right end of the connecting rod. Two bidirectional worms are rotatably connected to the inner wall of the limiting rotating block, and the outer wall of the bidirectional worms meshes with the outer wall of the worm gear.

[0009] Furthermore, two adjustment knobs are rotatably connected to the front side of the second connecting block, and the front end of the bidirectional worm gear is fixedly connected to the rear end of the adjustment knobs.

[0010] Furthermore, the sealing assembly includes a sealing block fixedly connected to the left side of the valve's inner wall, a sealing ring fixedly connected to the right side of the valve's inner wall, and the inner wall of the sealing block on the left side being inserted into the outer wall of the sealing ring on the right side.

[0011] Furthermore, a plurality of second sealing strips are fixedly connected to the inner wall of the sealing ring, and a plurality of first sealing strips are fixedly connected to the outer wall of the sealing ring. The outer side of the inner wall of the left sealing block is inserted into the outer wall of the right first sealing strip, and the inner side of the inner wall of the left sealing block is inserted into the outer wall of the right second sealing strip.

[0012] Furthermore, the sealing ring, the first sealing strip, and the second sealing strip are all made of polyurethane rubber.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, by inserting the limiting block into the limiting groove, rotating the adjustment knob to rotate the bidirectional worm gear, the bidirectional worm gear meshes with the worm wheel to rotate the worm wheel, the worm wheel rotates to drive the connecting rod to rotate, the connecting rod rotates to drive the limiting block to rotate, the limiting block abuts against the inner wall of the limiting groove to fix the limiting block, thus connecting the two valves.

[0015] 2. In this invention, the sealing ring drives the first and second sealing strips to insert into the sealing block. After the sealing ring is inserted into the sealing block, it occupies a certain space, narrowing the originally smooth flow path of the liquid and increasing the resistance to liquid flow. At the same time, the first and second sealing strips fit tightly against the inner and outer sides of the inner wall of the sealing block, further reducing the size of the gaps through which the liquid may pass, greatly increasing the resistance to liquid flow from these gaps, thereby increasing the sealing performance.

A sealing block 10 is fixedly connected to the left side of the inner wall of valve 1, and a sealing ring 11 is fixedly connected to the right side of the inner wall of valve 1. The inner wall of the left sealing block 10 is inserted into the outer wall of the right sealing ring 11.
