Description

Technical Field

[0001] This application relates to the technical field of ball valves, and in particular to a durable high-platform ball valve. Background Technology

[0002] High-platform ball valves are widely used in vacuum systems. They have low fluid resistance, and full-bore high-platform ball valves have virtually no flow resistance. They are also simple in structure, small in size, and light in weight. The sealing surface materials of high-platform ball valves widely use various plastics, which provide good sealing performance and can achieve a complete seal.

[0003] Regarding the aforementioned technologies, the applicant believes that in the current high-platform ball valve, the ball can generally be rotated by turning the valve handle. However, this design is prone to accidental activation, which can alter the state of the high-platform ball valve and affect its use. Therefore, there is still room for improvement. Utility Model Content

[0004] In order to reduce the possibility of the high-platform ball valve changing its state due to accidental contact with the valve handle, this application provides a durable high-platform ball valve.

[0005] The durable high-platform ball valve provided in this application adopts the following technical solution:

[0006] A durable high-platform ball valve includes a valve body with an internal valve stem and a valve handle connected to the valve body. The valve handle is provided with an anti-accidental contact structure, which includes a locking plate movably connected to the valve handle and a locking groove formed on the valve body. The locking plate is disposed opposite to the valve handle and can be inserted into the locking groove, and the locking plate is fixed in the locking groove by the locking structure. The locking structure includes a plug-in plate, which is fixed to the opposite locking plate and inserted into the locking groove.

[0007] By adopting the above technical solution, the locking plate on the valve handle is fixed to the locking groove of the valve body using a locking structure, and the positioning effect is further achieved by setting and inserting the plug plate. This can effectively prevent the valve handle from rotating relative to the valve body, thereby preventing the operator from accidentally touching the valve handle and reducing the situation where the state of the high-platform ball valve changes due to accidental touch.

[0008] Preferably, the locking structure further includes a protrusion and a slot, the protrusion being deformable and fixed to the plug plate, and the slot being formed on the side wall of the locking groove for the deformable protrusion to engage and position.

[0009] By adopting the above technical solution, the deformable protrusion enters the locking groove through deformation and is positioned in the groove by deformation reset, thereby achieving the purpose of fixing the plug-in plate and the locking plate.

[0010] Preferably, the locking structure further includes a magnetic block and a magnet. The magnetic block is fixed to the adjacent ends of the opposite plug-in plates, and the magnet is fixed to the corresponding end wall of the locking groove. The magnetic block and the magnet are magnetically attracted and fixed together.

[0011] By adopting the above technical solution, the magnetic block and magnet are further magnetically fixed, improving the positioning effect of the plug plate in the locking groove, further locking the position of the valve handle relative to the valve body, and achieving an effective anti-accidental contact effect.

[0012] Preferably, the locking plate extends from one end inside the valve handle and is fixed to a mounting plate that is lifted and connected inside the valve handle, and a connecting spring is fixed between the opposite mounting plates.

[0013] By adopting the above technical solution, the mounting plate makes the locking plate stably connected to the valve handle, and the connecting spring makes the opposite mounting plates have a force that brings them closer to each other, which helps to improve the stability of the opposite plug plates after they are fixed.

[0014] Preferably, the valve handle has a lifting groove for the locking plate and the mounting plate to move; a fixing block extends and is fixed on the valve stem, the fixing block has a connecting groove for the insertion plate to be inserted, and the side wall of the connecting groove has a groove for the protrusion to engage.

[0015] By adopting the above technical solution, the fixing block provides extension space for the valve stem, which facilitates the insertion of the plug plate; on the one hand, the plug plate can be fixed on the valve body to lock the valve handle, and on the other hand, when the plug plate is fixed on the valve stem, the synchronous rotation stability of the valve handle and the valve stem can be improved.

[0016] Preferably, the side wall of the locking plate is provided with a clamping opening for the clamp to hold.

[0017] By adopting the above technical solution, the clamping port can be easily clamped by a clamp after the corresponding plug-in plate is positioned for unlocking operation.

[0018] Preferably, the valve body surface is coated with a corrosion-resistant layer.

[0019] By adopting the above technical solutions, the corrosion-resistant layer can improve the corrosion resistance of the valve body, thereby extending its service life and improving its durability.

[0020] Preferably, the corrosion-resistant layer is a polytetrafluoroethylene (PTFE) anti-corrosion layer.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] The locking structure is used to fix the locking plate on the valve handle to the locking groove of the valve body. The positioning effect is further achieved by setting and inserting the plug plate. This can effectively prevent the valve handle from rotating relative to the valve body, thereby preventing the operator from accidentally touching the valve handle and reducing the situation where the state of the high platform ball valve changes due to accidental touch.

[0023] The deformable protrusion enters the locking groove through deformation and is positioned in the groove by deformation reset, thus fixing the plug plate and the locking plate; the magnetic block and magnet further magnetically fix it, improving the positioning effect of the plug plate in the locking groove, further locking the position of the valve handle relative to the valve body, and achieving the effect of effectively preventing accidental contact.

[0024] The fixing block provides extension space for the valve stem, facilitating the insertion of the plug plate; on the one hand, fixing the plug plate to the valve body can lock the valve handle, and on the other hand, fixing the plug plate to the valve stem can improve the synchronous rotation stability of the valve handle and valve stem.
