Description

The utility model relates to devices for shutting off the flow of any medium, namely, liquid in the form of water in the event of an emergency in the water supply network.

A well-known water valve containing a housing with an external male thread and an internal longitudinal bypass channel having an end entrance and lateral exit windows, a lock nut, lock plates and an end gasket, RU No. 27396 U1, E03C 1/04, 2003.01.27.

Known valve head of sanitary fittings, including a hollow cylindrical body with an external thread for fastening in the fitting seat, and used in water supply networks when it becomes necessary to block the flow of the working medium, RU No. 2162180 C1, F16K 3/08, 2001.01.20.

Known devices are designed to control (overlap) the flow of a liquid medium.

A device for shutting off the water supply during an abnormal mode of operation of the water supply network, comprising water intake fittings installed on the supply pipe, in front of which shutoff valves are installed, made with the possibility of actuation if any

water leaks in the form of an open solenoid valve electrically connected through a control unit with water sensors, RU No. 2232852 C1, E03C 1/00, G05D 7/00, 2004.07.20; RU No. 74140 U1, Е03С 1/00, G05D 7/00, 2008.06.20.

This technical solution was adopted as the "closest analogue" of this utility model.

In the device of the "closest analogue", the shutoff valves are made in the form of a ball actuator consisting of a ball valve and an electric actuator connected to a power supply and a liquid presence sensor, and for this, the device of the "closest analogue" from emergency operation to the operation mode requires a short voltage shutdown power supply of the control unit, which complicates the device, reduces its reliability, performance and functionality.

The basis of this utility model is the solution to a problem that allows to simplify the device, increase its reliability, performance, functionality and ensure the tightness of shut-off valves in case of emergency.

The technical result of this utility model is to implement a device with a valve, a fitting, a nut and a connecting guide if the valve has a core, a spring, a shutter, a locking washer and an airtight cup.

According to the utility model, this problem is solved due to the fact that the device for emergency shutdown of the flow, mainly liquid in the form of water, contains at least one stop valve installed on the production hose, which can be activated in emergency situations.

The device comprises a fitting, a nut equipped with a conical sealing gasket, a connecting guide provided with a sealing

ring, and as a stop valve - a valve. On the outer surface of the valve body, at one end, a thread is made for the fitting, and on the other an axial hole. The valve contains a core with channels for water passage, a spring, a lock with holes, a fixing washer and a sealed cup. A sealed glass is installed in the housing, made with an axial hole in its bottom and with a thickened annular rim on its neck. The thickened annular rim is placed in the annular groove of the fitting. A locking washer is placed on the outside of the bottom of the sealed cup. A core with channels for water passage, a shutter with holes and a spring are placed inside an airtight cup. The bolt with holes is interfaced with the connecting guide and has the ability to interact with the spring.

The applicant has not identified sources containing information about the technical solution that is identical to the features given in the formula of this utility model, this determines, according to the applicant, the utility model meets the criterion of “novelty”.

The essence of the utility model is illustrated in the drawing, which shows a device for emergency shutdown of the flow, section.

The device comprises a valve 1, a fitting 2, a nut 3, and a connecting guide 4.

Valve 1 contains:

Case - 5,

thread (on housing 5) - 6.

The core with channels for the passage of water - 7.

Spring - 8.

Shutter with holes - 9.

Lock washer - 10.

Sealed glass - 11,

bottom (cup 11) - 12,

neck (cup 11) - 13,

thickened annular rim (neck 13) - 14.

The fitting 2 contains:

Annular Groove - 15.

Nut 3 contains:

Conical gasket - 16.

The connecting guide 4 contains:

O-ring - 17.

The device comprises a fitting 2, a nut 3, a connecting guide 4 and a valve 1. The nut 3 is provided with a conical sealing gasket. The connecting guide 4 is provided with a sealing ring 17.

On the outer surface of the housing 5 of the valve 1, at one end, a thread 6 is made for the fitting 2, and on the other an axial hole.

The valve 1 contains a core with channels for the passage of water 7, a spring 8, a shutter with holes 9, a fixing washer 10 and an airtight cup 11.

A sealed cup 11 is installed in the housing 1, is made with an axial hole in its bottom 12 and with a thickened annular rim 14 on its neck 13. The thickened annular rim 14 is placed in the annular groove 15 of the fitting 2.

A locking washer is placed on the outside of the bottom 12 of the sealed cup 11.

A core with channels for the passage of water 7, a shutter with holes 9 and a spring 8 are placed inside the sealed cup 11. The shutter with holes 9 is interfaced with a connecting guide 4 and has the ability to interact with the spring 8.

Emergency shutdown of the stream is as follows. When the service hose (not shown) is not damaged, the water pressure before and after valve 1 is the same. In the event of a flow breakdown, the pressure in the production hose installed after valve 1 drops sharply and valve 1, under the pressure of the water, shuts off its supply to the production hose. Water enters the shutter 9, compresses the spring 8 and passes through the channels of the core 7.

To restore the water supply, it is necessary to equalize the pressure before and after valve 1. After replacing the damaged operating

hose, it is enough to shut off the water supply by unscrewing valve 1 until it clicks (typical for returning valve 1 to its original position) and tighten it again.

The presence in the device of the valve 1, fitting 2, nut 3 and connecting guide 4 simplifies the device.

The implementation of the sealed glass 11 and installing it in the housing 1 increases the reliability of the device.

Placement in a sealed cup 11 of the core with channels for the passage of water 7, the shutter with holes 9 and the spring 8 increases the reliability of the device and its functionality.

The coupling of the shutter with the holes 9 with the guide sleeve 4, the possibility of its interaction with the spring 8 and the installation of the locking washer 10 on the outside of the bottom 12 of the sealed glass 11 improves the performance of the device.

The implementation of the thickened annular rim 14 on the neck 13 of the sealed glass 11 and placing it in the annular groove 15 of the fitting 2 can improve the reliability of the device.

The implementation of the conical gasket 16 in the nut 3 ensures the tightness of the valve 1 when connected to the production hose.

The implementation of the sealing ring 17 in the connecting guide 4 ensures the tightness of the valve 1 in case of emergency.

The proposed device used parts and components widely used in valves, and the manufacture of prototypes of LLC Monolit and the testing determine, according to the applicant, its compliance with the criterion of "industrial applicability".
