Abstract
The utility model relates to a control valve of toilet water tank. The utility model can be used to solve the defects of complicated structure and bothersome parts production and assembly existing in the prior toilet water saving valve. The utility model is characterized in that the valve body is tubular shape, and an external thread is arranged one end of the valve body. A shoulder is arranged in the inner cavity of the valve body, and an internal thread through hole which is provided with a pipe joint is arranged between the valve body shoulder and the external thread. A valve stem is cylinder shape, and a shaft shoulder is arranged on one end of the valve stem. A cylindrical spring, a gasket, and an O-shaped sealing ring are installed on the valve stem next to the shaft shoulder. A water sealing rubber sealing ring is arranged at the end of the valve stem. The utility model can be used to replace a water saving valve of a toilet water tank.
Description
The utility model relates to the water tank control valve of water-closet.
A kind of water closet water-saving valve is arranged in the prior art, water-saving rate exceedes 80%, this technology is disclosed in the 22nd page in o. 11th (Shanghai is energy-conservation) periodical in 1991, introduce this water-saving valve in the literary composition by " valve body first half, valve body are latter half of, valve rod, spring, pin, casing joint, control crank etc. form ", the structure more complicated, part manufacturing and assembling are all cumbersome.
The purpose of this utility model is when reaching the equal usefulness of lavatory water-saving valve, and a kind of simple in structure, manufacturing and water closet control valve easy to assembly are provided.
The utility model is by valve body, valve rod, spring, sealing ring, packing ring is formed, it is characterized in that valve body is a tubular body, the one end has for the external screw thread that connects water inlet pipe, the stage casing of body cavity has convex shoulder one, the internal thread through hole of a vertical valve body axis for the mounting pipe joint arranged on the valve body between body cavity convex shoulder and the valve body external screw thread, valve rod is a cylinder, the one end has a shaft shoulder, install a cylindrical spring from the shaft shoulder of valve rod in regular turn along valve rod, a packing ring and an O RunddichtringO, cylindrical spring through packing ring the O RunddichtringO is pressed on body cavity convex shoulder hole and valve rod around, valve rod stretches to valve body through body cavity convex shoulder hole an externally threaded end, valve stem end is ined succession one section bolt in order to assemble a watertight rubber seal of closing valve pocket, and the watertight rubber seal is fixed tightly on the bolt of valve stem end with packing ring and nut.
The utility model does not need to be provided with control crank, pin, pin and member such as climbs, compare with the water closet water-saving valve of prior art, part obviously reduces, former and later two half ones of valve body change whole the manufacturing into, and structure more becomes rationally, part manufacturing and assemble all easier.
The explanation of accompanying drawing drawing: accompanying drawing is an assembling drawing of the present utility model, and 1 is valve body among the figure; The 2nd, valve rod, the convex shoulder hole of valve rod cylinder and body cavity movingly, the shaft shoulder of valve rod one end and body cavity are movingly; The 3rd, cylindrical spring; The 4th, packing ring; The 5th, the O RunddichtringO; The 6th, the watertight rubber seal; The 7th, packing ring; The 8th, nut.
Realize that best mode of the present utility model is to make positive hexagon at the valve body cylinder at valve body 1 attaching union place, so that the installation of union and valve body is set, make the taper hole shape in the aperture that the body cavity convex shoulder contacts with the O RunddichtringO, make sealing ring reach the better seal effect, the mode of valve stem end assembling watertight rubber seal also can be taked at the end face of valve stem end screw to be set, and uses fixedly watertight rubber seal of screw and packing ring.
