The known combined water limiting control device consists of a water supply limiting device in the form of a ball valve with a protection unit against unauthorized access to the rotary mechanism using a magnetic coupling equipped with a cap with a hole for sealing, a coarse filter with an opening in the lower part for sealing and an additional ball valve with a handle, characterized in that the additional ball valve is made in one housing with a coarse filter and placed after the device water supply restriction, and for cold water supply, the supply restriction device comprises a second hole of small diameter, perpendicular to the main hole.

Thanks to this design, it is possible to not only limit the water supply in the area of responsibility of the public utility contractor (IKU), but also provide the ability to shut off the water supply to replace the coarse filter, which, located in front of the cold water or hot water meter, serves to protect them from pollution.

Description

The utility model relates to the housing and communal services (HCS) system and can be used to control the restriction of the supply of hot (hot water) and cold (cold water) in the systems entering a separate apartment, if the owner of the apartment has arrears of payment for consumed utility resources.

Suppliers of utilities resources and providers of utilities (IKU) represented by management companies (UK), homeowners' associations (HOAs) are trying to use various methods of dealing with defaulters, but they are all ineffective and not complex due to lack of technical capabilities and lack of access to communications (water supply systems) located on the territory of the non-payer.

In accordance with the current Rules for the provision of public utilities (Decree of the Government of the Russian Federation No. 354 dated 05/06/2011), the limitation of the provided communal services (electricity, gas, hot and cold water) is allowed after a written notification to the owner of the apartment and after the expiration of the period established by the rules if debt in the amount of a monthly indicator.

In recent years, devices have been used to solve the technical problems of introducing water restrictions on hot water and hot water supply systems, which can be used to limit (for cold water) the resources supplied to the apartment of a consumer-debtor and to completely stop the supply of hot water. The implementation of various types of work to restrict the supply of hot and cold water, in the absence of such devices installed during construction, in apartment buildings (MKD) with vertical wiring is difficult, but possible under certain conditions.

Currently, in many cases, in the new MCD, the water supply system is routed according to the horizontal scheme, when the metering devices for the consumption of hot water and hot water are moved outside the apartments and installed on the landing in a special cabinet. This design is convenient from the point of view of taking readings of meters for consumed resources, because with the location of metering devices in the apartment this is not always possible. At the same time, it is possible to install such technical equipment in front of the cold water and hot water metering devices in the MKD with vertical wiring in municipal housing or by court decision.

In accordance with the Rules for the use of public water supply and sewage systems (PP of the Russian Federation No. 167 of 02/12/1999), an appendix should be attached to the contract between the consumer and the IKU, which describes the zones of differentiation of responsibility in an apartment building (the boundary of the operational responsibility of the consumer and the IKU) . This document should indicate the zones for which the consumer and IKU are responsible, and the second side has no reason to intervene in the operating modes of the devices for which the first side is responsible. Thus, IKU has a real opportunity to place a water control device in its area of responsibility, but at the same time some technical capabilities should be provided for controlling such devices. In fact, now the zone of delineation of responsibility is shutoff valves (which can serve as a ball valve, with which the owner of the apartment can stop the water supply to his apartment). Water control devices, firstly, should be able to use them to impose restrictions (partial or full) on water supply (cold water and hot water) and, secondly, they should have protection against unauthorized actions by unauthorized persons when trying to remove such restrictions.

There is a water control device in the form of a ball valve (Building codes and rules. Internal water supply and sewerage of buildings. SNiP 2.04.01-85), with the help of which shutdown or connection of cold or hot water can be carried out. This water limitation control device has several disadvantages. With its help it is impossible to partially limit the supply of cold water. There is also no protection system against unauthorized actions by unauthorized persons, which does not allow the full use of these taps to control water restrictions.

Another close to the proposed combined water control control device is a water control control device (RF Patent No. 143769), consisting of a device for shutting off the liquid supply in the form of a ball valve with a protection unit against unauthorized access to the rotary mechanism and a rough filter placed in front of it. This water limitation control device has a number of significant disadvantages. When installed in a water supply system in accordance with the requirements of SNiP 2.04.01-85, it is necessary to have shutoff valves (a conventional ball valve with a handle) to completely shut off the water supply inside the apartment in case of leaks or when replacing a meter for hot or cold water consumption. In this regard, it is necessary to have additional transitional connecting elements for switching this water limitation control device with a conventional ball valve, which complicates the entire structure and increases the connecting dimensions of all devices. In addition, in accordance with the requirements of the RF PP No. 354 (p. 114), the node of the mechanism of protection against unauthorized access is subject to mandatory sealing, which is not mentioned in the prototype. The design of the water limiting control device includes a coarse filter that has a threaded plug. This is necessary for periodic cleaning of the coarse filter when it is clogged. The presence of a threaded connection of the plug with the body of the water limiting device itself allows unscrupulous consumers to embezzle the consumed communal resources by installing a pipe with a hose instead of this plug. Such cases of theft of hot and cold water without taking into account the consumption of resources by meters (a coarse filter is installed in front of the meter) are very common and IKU are constantly faced with them. In the case of the introduction of a partial or complete restriction of water supply, an unscrupulous payer can take advantage of this theft method by installing a threaded pipe with a hose instead of a plug bypassing the water control control device.

Closest to the proposed combined water limitation control device is RF Patent No. 151471. This device consists of a fluid shut-off device in the form of a ball valve with a protection unit against unauthorized access to the rotary mechanism, equipped with a sealing cap, a coarse filter with an opening for sealing in the lower part and an additional ball valve with a handle. This combined water limiting device has a significant drawback. Due to the fact that the coarse filter is located before the additional ball valve, in case of contamination it is necessary to turn off the water supply throughout the riser to which the other users are connected. This makes it difficult to carry out the cleaning procedure, and also causes significant inconvenience when turning off the water supply to other users who are connected to this common water supply system.

The technical result of the proposed utility model is that in the proposed water limitation control device, consisting of a water supply shutoff device in the form of a ball valve with a protection unit against unauthorized access to the rotary mechanism, equipped with a sealing cap, a rough filter with a sealing hole in the lower part and an additional ball valve with a handle, there are differences in that the additional ball valve is made in one housing with a filter ruboy placed after purification and restriction device supplying water, wherein the cold water feed limiting device comprises a second small diameter hole formed perpendicular to the main opening.

The proposed combined water limitation control device makes it possible not only to affect non-payers for hot water and cold water by introducing a restriction (partial or full), but also, if necessary, painlessly for other users to shut off the water supply to a specific user using an additional ball valve for filter replacement rough cleaning. This is done using a second ball valve with a handle, combined with a coarse filter and located in front of the water control device. Therefore, the ball valve passes the zone of distribution of responsibility of the consumer and IKU. In turn, the water limitation control device lies on the other side of the zone of responsibility and it is served by an IKU, access to which is prohibited in accordance with the delimitation of zones of responsibility and is additionally provided by a protection center against unauthorized access. Also, a cap is installed on the protection unit, in which there is an opening for sealing, which is provided for by the RF software No. 354. All sealing areas (access protection unit and plug of the coarse filter) are located in the area of responsibility of the IKU and it is forbidden for the consumer to perform unauthorized actions in this area (these conditions are prescribed in the RF PP No. 167). The use of such innovations in the combined water control device allows expanding the capabilities of the new device, providing the necessary level of protection against unauthorized actions by unscrupulous consumers and creates the conditions for favorable cleaning procedures for the coarse filter.

The technical result of the proposed utility model is achieved by the fact that in the proposed water limitation control, consisting of a water supply restriction device in the form of a ball valve with a protection unit against unauthorized access to the rotary mechanism using a magnetic coupling equipped with a sealing cap, a coarse filter with an opening for sealing in the lower part and an additional ball valve with a handle, and the additional ball valve is made in one housing with a coarse filter and placed after the device for restricting the supply of water supply, and for cold water supply, the device for restricting the supply contains a second hole of small diameter perpendicular to the main hole.

As a result of this technical solution, it is possible to implement not only the restriction (partial or full) of the water supply that the IKU performs, but also, if necessary, carry out the procedure for replacing the coarse filter without creating inconvenience to all other users.

An additional ball valve with a handle in such a combined device performs the function of shutoff valves and passes through it the zone of differentiation of responsibility between the IKU and the consumer, and to protect against unauthorized actions for unaccounted water consumption and the failure of the protection unit on the main ball valve of the combined water limiting control device in the cap , which is worn on the protection unit, and outside the plug of the coarse filter there are holes for sealing. In addition, an additional tap is used when cleaning the coarse filter and replacing the HVS or GSV IKU counter, as well as by the consumer in the event of leaks or replacing the HVS and DHW taps located in the area of responsibility of the owner of the room.

Thus, the proposed water control device combined through the use of the proposed technical solutions helps to eliminate all of the above disadvantages of the above prototype.

A general view of the proposed combined water limitation control device (hereinafter referred to as UVOK) is shown in FIG. It consists of a water supply restriction device 1, to which water supply from the main riser is connected to the left side 2. It contains inside the site of protection against unauthorized access 3 to the mechanism using a magnetic coupling and is closed by a cap 4 with an opening 6 for sealing. The cap 4 is put on the protection unit 3 from unauthorized access to the rotary mechanism of the main ball valve of the combined water control device. After the device for restricting water supply 1, an additional ball valve 5 with a handle 7 is placed, made in one housing with a coarse filter 9, which has a hole 8 in the lower part for sealing in case of unauthorized interference with the aim of stealing water bypassing the water meter. On the right side 10 of the coarse filter, fittings are connected, through which the consumer receives cold water and whether hot water.

The proposed combined water control device was implemented using the following components. As a basis, a water limitation control device (UVO) was used, made on the basis of a patented utility model (RF Patent No. 143769). An additional ball valve 5 with a handle 7 with a nominal bore diameter l / 2Dn was installed to the device 1 on the right in the direction of movement of the water for carrying out procedures for shutting off the water supply. This additional ball valve was located in one housing with a coarse filter 9 (crane filter). A hole 8 with a diameter of 2 mm was made in the lower part of the coarse filter plug, and the cap 4 for installation on the protection unit 3 was made of polyethylene, with different colors for cold water supply (blue) and hot water supply (red).

Work with the combined water limitation control device is carried out as follows (we give the case when the UVOK device is located outside the apartment on the landing).

After installing the combined water control control device, the public services executor seals the protection unit and the plug of the coarse filter.

After the fact that the consumer has a debt of more than 1 calculated monthly indicator is established, within the framework of the existing Rules for the provision of public services (RF PP No. 354 of 06.06.2011), he is informed and warned of an impending restriction on the supply of the resource (hot water supply or hot water supply). If the consumer does not pay off the debt within the time specified in the warning, then a resource supply restriction is introduced for him (full for hot water supply or partial for hot water supply by turning the ball of the water supply restriction device 90 °). To access the restriction device, the utility contractor (IKU or the supplier’s representative), using the socket wrench, carries out all the necessary procedures for installing the rotary mechanism in the desired position, first removing the seal on the cap and removing the magnetic latch using the same key. After removing the key from the lock, this state is fixed with a magnetic latch and a cap is installed on top, which is sealed.

This water limitation control device can be used in the housing and communal services system of the Russian Federation and other CIS countries as a technical means for implementing a method of influencing non-payers for housing and communal services, which allows for the repayment of debts for housing services. And this, in turn, will make it possible to return huge financial resources to the budget and direct them to modernize the existing housing and communal services system.

The proposed measures for influencing consumer debtors for housing and communal services carried out using the proposed combined water control devices are more lenient compared to the traditional complete cessation of water supply, humane (because for cold water supply the full supply of communal resources does not stop, but the degree of comfort decreases) and have legal protection.

For water supply systems with hosted metering devices for consumption of communal resources in the consumer’s apartment, the use of the water control device installed in the consumer’s apartment is somewhat different and may coincide in time with periodic visits to the IKU apartment to verify meter readings, as well as with a court decision to install such devices to the consumer-debtor. At this time, when determining the presence of debt, the representative of the IKU will be able, by warning the consumer, to establish the necessary restriction using the water control device located in his area of responsibility and in accordance with the differentiation of areas of responsibility between the consumer and the utility provider.

The practical use of the proposed combined water control device has shown its effectiveness as an impact on debtor consumers, and this has contributed to an increase in payment discipline in the housing sector.
