Abstract
The utility model discloses a ball valve which comprises a valve body, a valve core, a valve handle and a hand lever. The ball valve is structurally characterized in that the valve core and the valve handle are connected and are disposed in the valve body, with the upper end of the valve handle extending out of the valve body to be fixed with the hand lever; a gasket ring is arranged between the valve handle and the valve core; a groove is arranged at the joint of the valve core and the valve handle; the lower end of the valve handle is provided with a lug boss which matches with the lug boss; the hand lever and the valve body are made of PPR material and are fixed through a bolt, while the valve core and the valve handle are made of steel; the gasket ring is made of composite polymeric plastic ethylene. The ball valve is of small friction, good sealing performance and long service life.
Description
Technical field
The utility model relates to a kind of ball valve.
Background technique
The spool of ball valve at present commonly used is made of copper, and valve body etc. are made by other metallic material, and its common drawback is that the friction between spool and the valve body is comparatively serious, and wearing and tearing can make the sealability variation, cause seepage, and also reduce working life thereupon.
Summary of the invention
Technical problem to be solved in the utility model provides the ball valve of a kind of little, good seal performance of rubbing, long service life.
The technical scheme in the invention for solving the above technical problem is: this ball valve comprises valve body, spool, valve rod and handle, its structural feature is that described spool and valve rod are positioned at valve body, spool is connected with valve rod, the upper end of valve rod is stretched out valve body and is fixed with handle, is provided with seal ring between valve rod and the spool.
The joint of spool described in the utility model and valve rod is a groove, and the lower end of valve rod has projection, and groove matches with projection.
Handle described in the utility model and valve body fix by bolt.
Valve body described in the utility model and handle are the PPR material, and spool and valve rod are steel matter.
Seal ring described in the utility model is moulded multiple ethene material for gathering.
The utility model compared with prior art, have following beneficial effect: valve body and handle are the PPR material, spool and valve rod are steel matter, wear-resisting property between the two is good, and structural strength and sealability have been guaranteed simultaneously, also prolong to some extent its working life, and environment friendly and pollution-free, do not play rust, volume is light.
