Description

The utility model is used in housing and communal services, mainly for the automatic closure of water supply networks, faucets installed in public toilets, in water and rail transport, as well as in a private housing stock.

Cranes are known in the art (for example, the construction of J. Brahm) having a housing with holes for water inlet and outlet and a threaded cavity for installing a locking spindle assembly.

In such a crane, the locking unit is mounted on the drive (spindle) with the possibility of rotation and vertical movement.

The spindle is mounted in a housing with stuffing box seal.

The disadvantages of this crane are lack of reliability and limited consumer capabilities. Limited consumer opportunities are explained by the fact that such a valve during periods of shutdown of pressure (pressure) in the water supply line does not provide disconnection of the latter with the consumer when the valve is opened and when it is in the “open” position (for example, due to consumer forgetfulness), which subsequently leads to uncontrolled water outflow, as well as the lack of control of water flow as necessary.

For the largest number of structural elements, the technical solution "valve" according to Russian patent No. 2171411, IPC 7 F 16 K 1/02 was declared on 04/21/99, published on July 27, 01 as a prototype.

The valve comprises a housing, a seat, a locking unit, a heel, a locking element, a locking unit drive, a spring, an inlet and an outlet. This valve during periods of pressure reduction or shutdown in the supply line (pipe) provides disconnection from the consumer, but does not provide water flow as necessary in it, which is ultimately a drawback.

The objective of the utility model is to expand the consumer capabilities of the crane:

a) the possibility of regulating the flow of water, if necessary;

b) self-closing of the locking unit to prevent unauthorized water outflow from the tap.

To solve the problem in a faucet containing a housing with a saddle, inlet and outlet openings, a spring, a locking assembly and a locking assembly drive, according to a utility model, the faucet is equipped with a rod mounted on the same axis with a drive on the opposite side of the locking assembly and extending beyond the outlet, and the spring is tapered and placed between the end of the drive and the locking unit.

The supply of the proposed device with a rod mounted on the same axis with the drive on the opposite side and extending beyond the outlet, as well as the installation of a spring between the end of the drive and the locking assembly, automatically disconnects the consumer from the pressureless water supply line when opening the tap and when it is in the open position in case of consumer forgetfulness, prevents unauthorized water outflow and provides the ability to control the flow of water if necessary, i.e. creating a water saving mode. The implementation of the conical spring provides maximum compression with a minimum length, which gives maximum water flow.

The inventive utility model is different from the prototype, i.e. meets the criterion of "novelty" and does not follow explicitly from the studied prior art.

In addition, the proposed device can be manufactured on an industrial scale and find application in the automatic shutoff of the water flow, i.e. characterized by the criterion of "industrial applicability".

The essence of the proposed technical solution is illustrated by the drawing, where in Fig.1 - water tap in the actuator position is “closed”; in figure 2 - in the drive position "open on demand"; figure 3 - tap in the "water demand" position (by applying force P from bottom to top).

In the drawings marked with letters:

And - the maximum stroke of the actuator 7 in figure 1

And ¹ - the average stroke of the actuator 7 in figure 2

And ² is the minimum stroke of the actuator 7 in figure 4

With ¹ - the minimum value of the play of the locking node relative to the actuator 7 in figure 1; 3

C is the maximum value of the play of the locking node relative to the drive in figure 2; four

The proposed water tap comprises a housing 1 with a saddle 2 and an inlet and an outlet 3; 4 a conical spring 5 as the most easily compressible into a plane of minimum thickness, the locking assembly 6 and the drive the spindle of the locking assembly 7, the cylindrical rod 8. The locking assembly 6 is mounted by rolling on the drive 7 with an axial play “C” of the heel 9, which ensures independent movement of the assembly relative to the drive and vice versa; sealing element 10.

Water tap works as follows. When opening and closing the valve as previously known, the water pressure, the conical spring installed between the end face of the spindle and the rear side of the locking unit 6, the spindle 7 presses the locking unit 6 against the seat 2 when the spindle opens the pressure-free water supply line and the drive is in the open position on demand 2, the shutoff unit 6 under its own weight, the force of the spring 5 due to backlash "C" when "A ^1" to remain on the saddle 2 crane body 1 by disconnecting the pressureless sanitaroopasnuyu line from the consumer, thanks h th term is further improved water supply services, as corrosion resistance increases.

In this situation, it becomes possible, if there is water in the line, to control the flow of water as necessary in it. Why, on the teardrop-shaped part of the cylindrical rod 8, mounted coaxially with the spindle drive 7, the force P is periodically applied, from the bottom up.

In this case, the conical spring 5 is compressed, the backlash "C" will decrease, the locking unit 6 will move away from the seat 2 and will open the access of water to the outside. When you remove the force P from the rod 8 under the action of the spring 5 and the pressure of the water, the locking unit 6 will again be pressed against the seat 2.

Thus, the water faucet will acquire a water flow control mode, i.e. the opportunity to save it and the second is the self-closing mode of the locking node 6 when removing the force R.

As can be seen in figure 4 in the position of the spindle "C" and "A" - the heel 9 of the locking node 6 rests against the circled part of the spindle.

When the spindle reaches the position at which A ² reaches zero, i.e. reaches the stop, the locking unit 6 will rise by the amount of stroke and will open the constant access of water to the outside.

The implementation of the water tap according to the utility model provides an economical mode of operation of the tap, increases the service life of the water pipe, and prevents unauthorized water outflow.
