Abstract

FIELD: sanitation equipment.

SUBSTANCE: invention relates to sanitary devices. Method consists in application of user's hand vertical force to rigidly fixed nipple (16) rod-pusher (15), thereby causing its vertical movement upwards with subsequent action end of shank (17) rod-pusher (15) on ball-valve (20) and its separation from sealing gasket (11), as a result, valve seat is opened in the form of insert hole (7) and water is provided to lower volume (22) of nozzle housing (1). By displacement of contact surface of end surface of shank (17) with ball-valve (20) radially away from vertical axis of symmetry additional torque is created, which provides tilting of ball-valve (20) to side with subsequent opening of valve seat in form of hole for free passage of water. After termination of user's hand impact on rigidly fixed nipple (16) of rod-pusher (15), ball-valve (20) as a result of rolling under action of gravity rushes along walls of internal cone (8) into seat of valve in form of hole.

EFFECT: reduced force to open water supply by user's hand.

Description

The invention relates to methods of sanitary equipment used in housing and communal services, in public places, in medical institutions, in kindergartens and schools to save water consumption when using plumbing systems.

A known method of operation of a water tap with a valve retainer [1], which consists in moving the spherical valve rigidly fixed on the guide rod due to the longitudinal displacement of the rod itself when a user's hand is applied from the bottom upwards to the tap nipple. Returning the ball valve to the closed position is done by means of a return spring.

The main disadvantage of the known method of operation of a water tap with a valve retainer is the need for a significant user hand to open the water supply due to the rigid fixation of the spherical valve on the guide rod, and the presence of a return spring complicates the operation of the nozzle.

The aim of the invention is to eliminate the disadvantage of the known method of operation of the faucet, namely reducing the required effort to open the water supply by hand of the user.

The invention consists in the following.

Due to the displacement of the contact patch of the surface of the end of the shank with the ball-valve radially away from the vertical axis of symmetry, additional torque is created, which causes the ball-valve to tilt to the side with a much smaller effort of the user's hand compared to the prototype and the subsequent opening of the valve seat in the form of an opening free passage of water. The possibility of free movement of the valve ball as a result of rolling under the action of gravity along the walls of the inner cone into the valve seat in the form of an orifice greatly simplifies the work of the nozzle.

The solution of the problem is achieved by implementing a new way of working the nozzle on a tap or mixer for water supply. Graphic material explaining the invention is presented in the following figures:

FIG. 2 - nozzle housing, top view;

FIG. 7 - nozzle on the faucet or mixer with a filled upper cavity, the phase of readiness to supply water for consumption;

FIG. 8 - nozzle on the faucet or mixer in the phase of water supply for consumption needs.

The nozzle consists of a nozzle body 1 of cylindrical shape, in the upper part of which there is a thread 2 of internal or external design for mounting on a faucet or mixer (Fig. 1). In the center of the bottom wall 3 of the nozzle is located a guide hole 4 and multiple perforated holes 5 for the passage of water (Fig. 1, 2). On the inner wall of the upper part of the housing of the nozzle 1 there is a supporting step 6 (Fig. 1), on which the insert 7 is supported (Figs. 3, 4, 6). The insert 7 has an upper end part in the form of an internal cone 8 (FIG. 3, 4), ending with a valve seat in the form of an opening 9 and a ledge 10 (FIG. 3) for laying the sealing gasket 11 (FIG. 6). From the opposite end of the insert 7 on the legs 12, the guide ring 13 is held with the guide hole 14 (Fig. 3, 4). In the guide hole 4 of the body of the nozzle 1 (Fig. 1, 2) and the guide hole 14 of the guide ring 13 of the insert 7 (Fig. 3, 4), the push rod 15 (Fig. 5, 6) freely walks. At the end of the pusher rod 15 (Fig. 5, 6), coming out of the body of the nozzle 1 to the outside, the nipple 16 is rigidly fixed. From the inner end, the pusher rod 15 has a shank 17 with a diameter larger than the diameter of the pusher rod 15 and with the end face 18 cut at an angle in the form of an oblique flat cut. In the upper cavity 19 of the insert 7 above the inner cone 8 (Fig. 3, 6) is placed a ball-valve 20 (Fig. 6) with the possibility of free movement in the cavity 19.

The nozzle assembly (Fig. 6) is fixed by means of the nozzle body 1 through the sealing gasket 21 to the faucet or the faucet through the threaded connection 2 of internal or external performance, depending on the design features of the faucet or the faucet. The ball-valve 20, being in a free state, under the influence of gravity will lie in the valve seat in the form of a hole 9 (Fig. 3) on the sealing gasket 11, blocking this hole 9.

When the valve of the faucet or mixer is opened, the water under pressure fills the entire volume of the upper cavity 19 of the insert 7 (Fig. 7). Under the influence of the hydrodynamic pressure of water generated in the upper cavity of the nozzle 19 and the force of gravity acting on the ball-valve 20, the ball-valve 20 hermetically closes the valve seat in the form of the hole 9 of the insert 7, by means of a sealing gasket 11, thereby preventing water from entering the lower volume 22 of the nozzle body 1.

In order to supply water for consumption, it is necessary for the user to apply a vertical force with the hand to the rigidly fixed nipple 16 of the push rod 15 (Fig. 8). As a result, the pusher rod 15 moves vertically upward, acting by the end face 18 of the shank 17 of the pusher rod 15 on the ball-valve 20, tearing it away from the sealing gasket 11. As a result, the valve seat opens in the form of an opening 9 of the insert 7, thereby providing water access in the lower volume 22 of the nozzle housing 1. The pressure in the upper cavity of the nozzle 19 and the lower volume 22 of the nozzle housing 1 is leveled, water is poured out through the perforated holes 5 of the bottom wall 3 of the nozzle housing 1 to the outside for water consumption in the form of water jets 23 ( Fig. 8).

Due to the execution of the end 18 of the shank 17 (Fig. 5) in the form of an oblique flat cut, the contact patch of the surface of the end 18 of the shank 17 with the ball-valve 20 is radially away from the vertical axis of symmetry to the maximum possible distance (Fig. 8), which creates an additional torque, which provides tilting of the ball-valve 20 (Fig. 8) to the side with the subsequent opening of the valve seat in the form of an opening 9 for free passage of water, while significantly reducing the required applied force for the separation of the ball-cl Pan 20 of the gasket 11 and opening the valve seat in the form of holes 9.

To close the water supply for the needs of consumption through the nozzle, it is necessary to stop the impact of the user's hand on the rigidly fixed nipple 16 of the pusher rod 15 (Fig. 8). As a result, the pusher rod 15, under the influence of gravity, moves downward until it touches the shank 17 with the guide ring 13 of the insert 7. The impact on the ball valve 20 from the side of the rod pusher 15 stops and the ball valve 20 as a result of rolling under the action gravity rushes along the walls of the inner cone 8 into the valve seat in the form of a hole 9. As a result of the hydrodynamic pressure of water and gravity on the ball-valve 20, the valve seat in the form of the hole 9 of the insert 7 overlaps guide pads 11, thereby stopping the supply of water for consumption. The nozzle on the tap or mixer for water supply returns to its original state (Fig. 7).

The proposed method of operation of the nozzle on the faucet or mixer significantly reduces the efforts of the user's hand attached to the rigidly fixed nipple 16 of the pusher rod 15 to bias the ball-valve 20 with the subsequent opening of the valve seat in the form of the hole 9 (Fig. 6, 7, 8). This effect is achieved by displacing the contact patch radially away from the vertical axis of symmetry, thereby creating additional torque and thus tilting the ball-valve 20 to the side and then opening the valve seat in the form of an opening 9 for free passage of water for water consumption.

In addition, the possibility of free movement of the ball valve 20 as a result of rolling under the action of gravity along the walls of the inner cone 8 in the valve seat in the form of an opening 9 greatly simplifies the work of the nozzle (Fig. 7, 8).
