Abstract

FIELD: bathroom and lavatory equipment. SUBSTANCE: invention can be utilized in flush tanks of closet basins. Flush fixture includes extension with integrated launder, hemispherical elastic valve, flexible or rigid tie-rod, handle or knob. Seat of extension is tilted. Hemispherical elastic valve has fork with holes in ends mounted on horizontal uniaxial hooks made on launder on one side and flexible tie-rod with notched end on opposite side. Upper part of launder carries corner bracket anchored with the aid of clamp with screw. Vertical end of bracket has shape of fork with horizontal holes. Mobile lever with short arm possessing fork with horizontal uniaxial holes and long arm with two rows of holes is anchored in bracket. Notched end of flexible tie-rod of valve is fixed in long arm. Horizontal axle of rigid tie-rod of push button is fixed in holes of short arm. Rigid tie-rod has several axles arranged at different levels and is linked to knob with use of thread. Knob is mounted for reciprocating motion in guiding bushing anchored in hole of cover of flush tank by means of coupling nut. Spring which length is twice as short as distance between knob in free position and bottom of bushing is put on rigid tie-rod between knob and bottom of guiding bushing. EFFECT: simplified design and assembly, provision for versatility of application in flush tanks different in form and dimensions, increased reliability and economic consumption of water during operation, reduced usage of materials for manufacture. 1 dwg

Description

 The invention relates to sanitary equipment and can be used in flush tanks for toilets.

 Known drain valves (1) contains a release with combined overflow, hemispherical elastic valve, flexible or rigid traction, trigger handle or button.

 The technical result of the invention is to simplify the design and installation, to ensure universality of use in flushing cisterns that differ in shape and size, increase reliability, comfort and economy in water consumption during operation, reduce material consumption in production.

 To achieve this goal in the claimed drain valve containing a discharge with a combined overflow, a hemispherical elastic valve, a flexible or rigid rod, a trigger handle or a button, the outlet saddle is made inclined, the hemispherical elastic valve has a plug on one side with holes at the ends, mounted on horizontal coaxial hooks made on the overflow, on the opposite side a flexible rod, the end of which is jagged, in the upper part of the overflow with the help of a clamp with a screw, an angled bracket is fixed a unit, the vertical end of which is made in the form of a fork with horizontal holes, into which, using the axis, a movable lever is fixed with a short shoulder having a fork with horizontal coaxial holes and a long shoulder with two adjacent holes, with which the serrated end is fixed to it with a flexible thrust of the valve, in the holes of the fork of the short arm of the lever, the horizontal axis of the rigid thrust of the start button is fixed, the rigid thrust has several axes located at different levels, and using a thread and with a start button, which is arranged with the possibility of reciprocating movement in the guide sleeve, fixed with a union nut in the hole of the flush reservoir cover, a spring is located on the rigid rod between the button and the bottom of the guide sleeve, 2 times less than the distance between the button in the unpressed position and bottom of the sleeve.

 The drawing shows a General view of the drain valves with a push trigger button.

 The drain valve contains: outlet 1, nut 2, gasket 4, inclined seat 5, hemispherical floating elastic valve 6 with plug 7 and flexible rod 19, overflow 9 with hooks 8, angle bracket 11 with clamp 10, lever 12, rigid rod 13, spring 14, nut 15, sleeve 17, button 18.

 Installation of drain valves in the flushing tank is carried out in the following order.

 Issue 1 with gasket 4 is inserted into the bottom hole of the flushing tank 3 and secured with a nut 2. Unscrew the button 18 from the rigid rod 13, remove the sleeve 17 with the spring 14. Install the sleeve 17 in the hole of the lid 16 of the flushing tank and fix it with the nut 15. Insert the rigid rod into the hole of the sleeve 17, put on the spring 14 and screw the button 18.

 The reinforcement is adjusted for the height of a particular tank by moving the clamp 10 at the overflow 9, moving the lever to the corresponding axis of the rigid rod 13, and also moving the flexible rod 19 in the holes of the lever 12.

 The principle of operation of the claimed drain valves is as follows.

 When the useful volume of the flushing tank is filled with water (up to a level of 20 mm below the upper edge of the overflow 9), press button 18 all the way. In this case, the lever 12 lifts the flexible rod 19 and valve 6, which pops up due to the internal air bubble. After emptying the useful volume of water in the tank, the valve 6 loses buoyancy and lowers onto the inclined seat 5 and hermetically closes the outlet opening 1 for refilling the tank.

 The fittings allow you to lower part of the useful volume of water (small descent). To do this, press the button 18 until the spring 14 touches the button (until the sensation of increased effort on the button). In this case, the valve 6 opens, but does not pop up.

 Compared with the known claimed drain valves are simple in design, installation and adjustment, universal in use in tanks of various shapes and sizes, has increased reliability, durability and ease of use, economical in water consumption due to the ability to carry out small and large descents, technological in production with low material consumption and cost (can be made entirely of plastic and rubber).
