Abstract
The utility model relates to a pneumatic sealing type drain valve of a toilet cistern, which is an air chamber made of top-quality rubber. The air delivered into the air chamber by a button switch exerts pressure on a guide rod, and a conducting pipe drives a sealing valve to rise and discharge water by reactive force. The sealing valve is formed by combining a hollow ball crown and a hollow ball table. The utility model has the function of tightly sealing off the opening of a drain pipe in order to achieve the purpose of no water leakage. The utility model is mutually connected with a cistern by a hose, so the utility model is free from the limitation of the geometric size of the cistern, and the pneumatic sealing type drain valve of a toilet cistern can be used as an adapter member for various toilet cisterns.
Description
The utility model relates to step and valve technology, is a kind of vapour-pressure type sealed draw-off valve of tank for excrement pan, and it belongs to daily class.
The purpose of this utility model is to develop a kind of watertight sealed draw-off valve that promotes with vapour-pressure type.
The technical scheme that realizes the utility model purpose is such: air is exerted pressure to guide rod after importing air chamber, and conduit drives seal valve with reaction and upwards draws high, and carries out draining.The seal valve sealing draining mouth of pipe with special pearl structure reaches watertight purpose.
Connection of the present utility model is flexible pipe, is not subjected to the restriction of water tank physical dimension during installation, so can be used as the accessory of all kinds water tank.
The utility model concrete structure is provided by following examples and accompanying drawing (1-3).
Fig. 1-the 3rd, the sectional drawing of the utility model structure.Wherein: 1-air chamber cap, 2-air chamber, 3-garden tube, 4-hollow hemisphere, 5-conduit, 6-guide rod, 7-seal valve, 8-hollow spherical crown, the hollow billiard table of 9-, 10-guide bar support, the 11-draining mouth of pipe, 12-suction nozzle, 13-flexible pipe, the hollow garden of 14-frustum, 15-hollow ellipsoid hat.
Concrete structure of the present utility model and working condition now are described in detail in detail in conjunction with the accompanying drawings.
The vapour-pressure type sealed draw-off valve of tank for excrement pan of the present utility model comprises air chamber cap (1), air chamber (2), garden tube (3), hollow hemisphere (4), conduit (5), guide rod (6), seal valve (7), hollow spherical crown (8), hollow billiard table (9), guide bar support (10), the draining mouth of pipe (11), suction nozzle (12), flexible pipe (13), hollow garden frustum (14), hollow ellipsoid hat (15).The garden tube (3) that air chamber (2) is made for top-quality rubber, an end of garden tube (3) connect a thin hollow hemisphere (4) in garden tube (3), and it is enclosed within the air chamber cap (1).Suction nozzle (12) is arranged at air chamber cap (1) top.The air of being carried by press button enters air chamber (2) through flexible pipe (13), suction nozzle (12), the hollow hemisphere of air chamber (4) is outwards heaved, force in guide rod (6), guide rod (6) is fixed in guide bar support (10) top guide bar support (10) and links together with the draining mouth of pipe (11).Conduit this moment (5) drives seal valve (7) with reaction force and upwards rises, and carries out draining.The first half of seal valve (7) is the hollow spherical crown (8) that top-quality rubber is made, edge thickness increases gradually along its external diameter, because the structure of its spherical crown, upper pressure reasonably is evenly distributed to the edge, make its edge and the draining mouth of pipe (11) face identical closely, close sealing, thereby reach watertight purpose.Hollow spherical crown (8) also available hollow garden frustum (14) or hollow ellipsoid hat (15) replace.Lower Half is the billiard table (9) of TR thin rubber, and the synthetic big air chamber of two parts forms a float up and down, and when treating that water is discharged to the draining mouth of pipe (11), conduit (5) is owing to unlikely deflection is fallen in deadweight along guide rod (6).
The utility model is compared with existing tank for excrement pan draining valve, and the advantage that has has:
1. can be used as the accessory of any tank for excrement pan.
2. overcome the shortcoming of leaking.
3. easy to operate, good reliability.
Claims (3)
1. the pneumatic type sealed draw-off valve of tank for excrement pan, it comprises air chamber cap (1), air chamber (2), garden tube (3), hollow hemisphere (4), conduit (5), guide rod (6), seal valve (7), hollow spherical crown (8), hollow billiard table (9), guide bar support (10), the draining mouth of pipe (11), suction nozzle (12), flexible pipe (13), it is characterized in that the garden tube (3) that air chamber (2) is made for rubber, an end of garden tube (3) connects one at the inner hollow rubber hemisphere (4) of garden tube (3).
2. the vapour-pressure type sealed draw-off valve of tank for excrement pan according to claim 1, also comprise hollow garden frustum (14), hollow ellipsoid hat (15), the top that it is characterized in that seal valve (7) is the hollow spherical crown (8) that rubber is made, edge thickness increases gradually along its external diameter, its edge and the draining mouth of pipe (11) match, hollow spherical crown (8) also available hollow garden frustum (14) or hollow ellipsoid hat (15) replace, and the bottom is hollow billiard table (9), up and down two synthetic air chambers.
3. the vapour-pressure type sealed draw-off valve of tank for excrement pan according to claim 1, it is characterized in that guide rod (6) is fixed on guide bar support (10) top guide bar support (10) and is consolidated with the draining mouth of pipe (11), and conduit (5) can move up and down along guide rod (6).
