Abstract
The utility model discloses a valve core of a rotary-typed water valve, in particular to relate to the valve core of the rotary-typed water valve which closes the passage by the deformation of the elements. The utility model consists essentially of a sealing liner (2) and a rotor (1). The utility model is characterized in that the sealing liner (2) is in pipe-shape and is made of elastic sealing material; the rotor (1) is in column-shape; the external diameter of symmetrical sealing surfaces (5) and (6) of the central part of the rotor is equal to or slightly larger than the internal diameter of the sealing liner (2); the external diameter of two other starting surfaces (7) and (8) are less than the internal diameter of the sealing liner (2); the central part of the rotor is directly inserted into the sealing liner (2). The utility model adopts the rotor with unique shape deformation matched with the sealing liner, implements the object of simple installation and replacement of the sealing elements, has simple structure and low cost, and thoroughly solves the difficulties of running, bubbling, dropping and leakage of the prior valve.
Description
The utility model relates to a kind of spool of rotary water valve, more particularly relates to the spool that a kind of distortion by element comes the rotary water valve of close passage.
The ZL97201573.6 Chinese patent discloses a kind of spool that is made of valve rod and rubber.Its main feature is: valve rod (4) lower end has spiral shell button (5), valve rod (4) top (2) and rubber (6) top (1) cast solid, and being shaped as during rubber (6) unseal is arc, is shaped as barrel-shaped (see figure 1) when resetting.This model utility is owing to adopt the stretching elasticity sealed valve of rubber, and leakage proof is effective, and can prevent the secondary pollution of scale to water body.But because valve rod (4) top (2) and rubber (6) top (1) cast solid, and rubber is easily damaged parts, so processing and fabricating is complicated, and rubber needs to change whole spool after losing seal action.
Goal of the invention of the present utility model is to provide a kind of can overcome above-mentioned defective, and main seal element is easy to install and change, and opens, closes the spool with the rotary water valve of leakage proof better effects if.
Goal of the invention of the present utility model is achieved in that spool mainly is to be made of seal cartridge and rotor, seal cartridge is a tubulose, its two ends have the flange convex edge, can be directly as the Sealing when fixedly connected between the valve base element, seal cartridge adopts elaxtic seal to make, as rubber etc.; Rotor is a column, the external diameter of the sealing surface of its middle body symmetry equals or slightly greater than the internal diameter of seal cartridge, the external diameter that other two open faces is then less than the internal diameter of seal cartridge, preferably be inner concave shape, the middle body of rotor directly inserts in the seal cartridge, two ends can be used as the positioning shaft of rotor, and wherein an end can be installed handle.
After the middle body of rotor directly inserts seal cartridge, because the sealing surface external diameter of rotor middle body symmetry equals or slightly greater than the internal diameter of seal cartridge, the external diameter of seal cartridge remains unchanged, or slightly deformed, thereby can constitute the cut-off state of valve; The external diameters that other two open faces are then because less than the internal diameter or the indent of seal cartridge, and under the elastic force effect and the pressure of extraneous fluid of himself, the unlatching face of seal cartridge will produce distortion, the opening state of formation valve.Rotor relatively rotates in seal cartridge, just can make two relatively-stationary of seal cartridge to realize sealing or the variation of opening.
The utility model reaches the opening and closing of valve owing to adopted the rotor and the seal cartridge of original creation shape to cooperate with rotor deformation, has realized the seal element installation, has changed simple purpose; In addition, seal cartridge adopts elastic material, makes as free of contamination materials such as rubber, can avoid the secondary pollution of the corrosion of metal spool to water.The 3rd, adopt this structure spool, can realize the further simplification of valve closing and opening structure, reduce cost, and thoroughly solved the difficult problem of the run, drip, leak of conventional valves.
Give detailed description below with reference to accompanying drawing to an embodiment of the present utility model.
Fig. 1 is the prior art constructions schematic representation;
Fig. 2 is the sectional view of the utility model embodiment opening state;
Fig. 3 is the sectional view of the utility model embodiment closed condition
Referring to Fig. 2,3.Spool mainly is to be made of seal cartridge of tubulose (2) and rotor (1), and wherein the two ends of seal cartridge (2) have flange convex edge (4), and seal cartridge adopts rubber material to make; Rotor (1) is a column, the external diameter of the sealing surface of its middle body symmetry (5), (6) is slightly greater than the internal diameter of seal cartridge, other two faces (7), (8) are the indent circular arc of symmetry, the middle body of rotor directly inserts in the seal cartridge, two ends (9), (3) can be used as the positioning shaft of rotor, and wherein an end (3) can be installed handle.
Claims (4)
1, a kind of spool of rotary water valve mainly is to be made of seal cartridge (2) and rotor (1), and it is characterized in that: seal cartridge (2) is a tubulose, adopts elaxtic seal to make; Rotor (1) is a column, the external diameter of the sealing surface of its middle body symmetry (5), (6) equals or slightly greater than the internal diameter of seal cartridge (2), the external diameter of other two unlatching faces (7), (8) is less than the internal diameter of seal cartridge, and the middle body of rotor directly inserts in the seal cartridge (2).
2, the spool of rotary water valve according to claim 1 is characterized in that: the two ends of seal cartridge (2) have flange convex edge (4).
3, the spool of rotary water valve according to claim 1 and 2 is characterized in that: two unlatching faces (7) of rotor, (8) are indent circular arc,
