Description

Technical Field

[0001] This application relates to the field of valves, and in particular to an aluminum straight-through valve. Background Art

[0002] A straight-through valve is a commonly used fluid control device, mainly used to control the flow direction, flow rate, pressure and liquid level of liquids or gases. A straight-through valve usually consists of components such as a valve body, a valve cover, a valve seat, a valve core, and a spring. Its structure is simple and easy to use, and the on-off of the fluid is controlled by the opening and closing of the valve core. Straight-through valves are widely used in many fields such as industry, construction, water conservancy, aerospace, etc. because of their simple structure, convenient operation and accurate control.

[0003] However, the sealing surface between the valve core and the valve body of the existing straight-through valve is easily worn, and the service life is relatively short. After the sealing surface is worn, the liquid is likely to leak from the valve body, resulting in waste of resources. Utility Model Content

[0004] In order to reduce the probability of liquid leakage, this application provides an aluminum straight-through valve.

[0005] An aluminum straight-through valve provided by this application adopts the following technical solutions:

[0006] An aluminum straight-through valve includes a valve body, a valve tube, a fixing ring, a first sealing ring, a second sealing ring and a valve ball. The valve body is provided with a through cavity, and the outer wall of the valve body is provided with a driving port, which communicates with the through cavity. Both ends of the valve body are respectively provided with a connecting port and a fixing port, and both the connecting port and the fixing port communicate with the through cavity and are respectively arranged on both sides of the driving port. The outer wall of the valve tube is threadedly connected to the inner wall of the connecting port, and the fixing ring is coaxially and fixedly connected to the inner wall of the fixing port. The first sealing ring is connected to one end of the valve tube facing the driving port, and the second sealing ring is connected to one end of the fixing ring facing the driving port. The inner wall of the first sealing ring is coaxially provided with a first abutting surface, and the inner wall of the second sealing ring is coaxially provided with a second abutting surface. The diameters of both the first abutting surface and the second abutting surface increase as they approach the driving port. Both ends of the valve ball respectively abut against the first abutting surface and the second abutting surface.

[0007] By adopting the above technical solutions, the first abutting surface improves the sealing performance between the valve ball and the first sealing ring, and the second abutting surface improves the sealing performance between the valve ball and the second sealing ring, increasing the contact area between the first sealing ring and the second sealing ring and the valve ball, reducing the probability of leakage due to wear of the sealing surface, extending the service life, and reducing the probability of liquid leakage.

[0008] Preferably, a limiting groove is provided at one end of the valve tube facing the valve ball. The limiting groove communicates with the pipe orifice of the valve tube, and the first sealing ring is embedded in the limiting groove, and the outer wall of the first sealing ring fits against the groove wall of the limiting groove.

[0009] By adopting the above technical solution, the limiting groove limits the installation position of the first sealing ring, so that the first sealing ring is not easily deformed and damaged during the rotation of the valve ball, thereby extending the service life of the first sealing ring and reducing the probability of liquid leakage.

[0010] Preferably, the minimum inner diameter of the first sealing ring is smaller than the diameter of the valve tube.

[0011] By adopting the above technical solution, the fluid pushes the first sealing ring to press against the valve ball during the flow process, thereby reducing the probability of liquid leakage.

[0013] By adopting the above technical solution, the positioning ring body abuts against the groove wall of the positioning ring groove, so that the liquid in the through cavity is not easy to leak, thereby reducing the probability of liquid leakage.

[0014] Preferably, it also includes a sealing ring, which is sleeved on the outer circumference of the valve tube, and is arranged between the first external thread and the positioning ring body, the outer wall of the sealing ring abuts the inner wall of the connecting port, and the inner wall of the sealing ring abuts the outer wall of the valve tube.

[0015] By adopting the above technical solution, the sealing ring improves the sealing performance between the valve tube and the valve body. If the first sealing ring or the second sealing ring is damaged, liquid is not likely to leak from the through cavity, thereby reducing the probability of liquid leakage.

[0016] Preferably, it also includes a valve stem, the end of the valve ball facing the drive port is provided with a mounting groove, the valve stem is coaxially rotatably connected to the inner wall of the drive port, the end of the valve stem facing the valve ball is fixedly connected to a mounting block, and the mounting block is embedded in the mounting groove.

[0017] By adopting the above technical solution, the valve stem is relatively fixed to the valve ball through the mounting block, and the valve ball is driven to rotate when the valve stem rotates, which is convenient for users to use.

[0018] Preferably, it also includes a waterproof ring, which is sleeved on the outer circumference of the valve stem, and the outer wall of the valve stem is coaxially provided with a fixed ring groove, the waterproof ring is embedded in the fixed ring groove, and the outer wall of the waterproof ring abuts against the inner wall of the drive port.

[0019] By adopting the above technical solution, the waterproof ring improves the sealing performance between the valve stem and the valve body. If the first sealing ring or the second sealing ring is damaged, liquid is not easy to leak from the through cavity, thereby reducing the probability of liquid leakage.

[0023] By adopting the above technical solution, the anti-slip ring makes it difficult for the valve stem to slip out of the drive port, thereby facilitating the stable use of the valve.

[0024] Preferably, it also includes a handle and a movable block, the outer wall of the handle is provided with a fixed groove, the end of the valve stem facing away from the valve ball is fixedly embedded in the fixed groove, the inner wall of the drive port is provided with a movable groove, the movable groove extends to the end away from the valve ball and passes through the valve body, the movable block is fixedly connected to the outer wall of the handle facing the valve body, and the movable block is slidably embedded in the movable groove.
