Anti-leakage durable copper valve

Abstract

The invention discloses an anti-leakage durable copper valve which comprises a valve body. A water inlet is formed in one side of the valve body, a valve port is arranged at one side of the water inlet, and a water outlet is formed in one side of the valve port. A valve element is arranged at the top of the valve port, the outer wall of the valve element is sleeved with a sealing sleeve, and a spherical groove is formed in the valve element. A valve rod is arranged at the top of the spherical groove, a sealing ring is arranged in the middle of the valve rod, and a padding bottom piece is arranged at the top of the sealing ring. Padding is arranged at the top of the padding bottom piece, a padding gland is arranged at the top of the padding, and a mounting cover is arranged at the top of the padding gland. A rotating handle is connected to the top of the valve rod, a valve deck is arranged at the top of the valve body, the position where the valve deck and the valve body make contact is provided with a sealing gasket and a fixing hole, and a bolt is arranged at the top of the fixing hole. Three circles of annular convex blocks are arranged on the valve port of the copper valve, three sealing rings can be formed during complete sealing, and the anti-leakage durable copper valve is good in anti-leakage performance and long in service life.

Description

technical field [0001] The invention relates to valves, in particular to a leak-proof and durable copper valve, which belongs to the technical field of valves. Background technique [0002] The valve is a control component in the fluid delivery system, which has functions such as cut-off, adjustment, flow diversion, reverse flow prevention, pressure stabilization, flow diversion or overflow pressure relief. Valves are widely used in daily life. The existing valves are generally metal valves. The valves made of metal materials are mainly made of copper materials, stainless steel materials, etc., and then loaded into the valve core, valve stem, Handles and other parts. Piston valves are mostly used in sewage and raw water systems. The piston in the existing piston valve is an integral part made of cast steel material. Moreover, after the ordinary valve is used for a period of time, the sealing sleeve of the valve core is easy to be damaged, so that the valve cannot stop the ...
