Abstract
The utility model relates to an internal pressure type water inlet device, which belongs to a water inlet device of a closet. A water inlet upper seat (6) is installed on a water inlet seat (3). A filtering net (4), an O-shaped ring (5), a rubber plug (7), and a pressing rod (8) are installed on the water inlet upper seat (6). The pressing rod (8) is hinged with a water pressing lever (10) by a positioning pin (9). A counterweight block (11) and a floating ball (12) are installed on the water pressing lever (10). When the internal pressure type water inlet device is sealed, the acting force of the internal pressure type water inlet device is the water deliver pressure of tap water. Not only sealing pressure is large, but also a water outlet is sealed form interior to exterior. A sealing surface is in conical surface sealing. The internal pressure type water inlet device has reliable work, long service life, high speed sealing process, convenient installation and connection, no water leakage, and low cost. The rubber plug is an integral structure. The internal pressure type water inlet device is suitable for a water inlet mechanism of a closet.
Description
The utility model relates to toilet water inlet device, particularly a kind of internal pressure type water inlet device.
The toilet water intake mechanism mainly is the pressure that utilizes the height of water to produce in the prior art, act on the water inlet by rubber plug, to reach sealing purpose, its major defect is, owing to be the external force sealing, so external force must be enough big, the shape of water inlet oral area must be got well, and sealing surface is narrow, these require, and not only manufacture difficulty is bigger, and be unfavorable for working life of sealing gasket, and the contamination resistance of sealing surface is poor simultaneously, and these shortcomings influence the working life of common water intake mechanism greatly.
The purpose of this utility model is: a kind of internal pressure type water inlet device is provided, it utilizes the water pushing pressure of tap water, seals water outlet from inside to outside, its good airproof performance, thereby improved the working life and the functional reliability of water intake mechanism greatly, solved the run, drip, leak phenomenon well.
Formation of the present utility model:, balancing weight stifled by influent base, rubber, filter screen, the water inlet seat of honour, depression bar, setting-out lever and ball float are formed, on influent base (3), be installed into seat waterborne (6), there are filter screen (4) and O shape circle (5) in influent base (3) top in the water inlet seat of honour (6), filter screen top in the water inlet seat of honour (6) has rubber to block up (7), rubber stifled above be depression bar (8), depression bar (8) is hinged by locating stud (9) and setting-out lever (10), goes up at setting-out lever (10) balancing weight (11) and ball float (12) are installed.Rubber stifled (7) is overall structure, and the centre is cylindrical, and two is conical.The water inlet seat of honour (6) is made up of secondary ladder outer cylinder and secondary stepped shaft endoporus, and big endoporus is a tapped hole, is threaded with influent base (3), has filter screen (4) and rubber to block up (7) in middle endoporus, and depression bar (8) is arranged in little endoporus.
Compared with the prior art, the utility model is simple in structure, reliable operation, with low cost, water-tight, long service life, install easy to connectly, during sealing, its active force is the water pushing pressure of tap water, not only the sealing load of more common water intake mechanism is big, and is to seal water outlet from inside to outside, and sealing surface is a conical surface seal, reliable operation, rubber is stifled to be overall structure, long service life, seal process speed is fast, and sealing strip is downward, so contamination resistance is strong.
Accompanying drawing is the utility model structural representation.
Embodiment of the present utility model: as shown in drawings, water inlet nut (1) and water inlet sealing gasket (2) are installed on the lower end screw rod of influent base (3), on the screw rod of upper end, be installed into seat waterborne (6), O shape circle (5) is installed in big endoporus bottom at the water inlet seat of honour (6), filter screen (4) and rubber stifled (7) are installed in middle endoporus, depression bar (8) is installed in little endoporus, depression bar (8) is hinged by locating stud (9) and setting-out lever (10), at the cantilever end of setting-out lever (10) balancing weight (11) and ball float (12) is installed.
During water inlet, rubber stifled (7) is under setting-out lever (10) and depression bar (8) active force, be in open mode, tap water can flow in the toilet water tank from the water inlet, when water arrives certain height, because the rising of ball float (12) has driven the setting-out lever and depression bar rises, make rubber stifled (7) under bourn acting force upwards suction seal mouth place water seal is lived.
When discharging water, along with the decline of water level, ball float, setting-out lever and depression bar are under action of gravity, and it is stifled to back down rubber, gets back to into water state.
Claims (3)
1, a kind of internal pressure type water inlet device,, balancing weight stifled by influent base, rubber, filter screen, the water inlet seat of honour, depression bar, setting-out lever and ball float are formed, it is characterized in that: on influent base (3), be installed into seat waterborne (6), there are filter screen (4) and O shape circle (5) in influent base (3) top in the water inlet seat of honour (6), filter screen top in the water inlet seat of honour (6) has rubber to block up (7), rubber stifled above be depression bar (8), depression bar (8) is hinged by locating stud (9) and setting-out lever (10), goes up at setting-out lever (10) balancing weight (11) and ball float (12) are installed.
2, internal pressure type water inlet device according to claim 1, it is characterized in that: rubber stifled (7) is overall structure, and the centre is cylindrical, two is conical.
