Description

Technical field

The invention generally relates to a differential hydraulic control valve, and more particularly, to a valve actuator for actuating a hydraulic control valve of a fire protection system.

State of the art

Automatic sprinkler fire extinguishing system is one of the most widely used fire protection devices. Such systems have sprinklers that are activated after the ambient temperature, such as a room or building, exceeds a predetermined value. After activation, sprinklers spray fluid in a building or building to extinguish a fire, preferably water. A sprinkler fire extinguishing system, depending on its configuration, is considered effective if it localizes or suppresses fire.

The sprinkler system can be equipped with a water supply system (for example, from a reservoir or through a domestic water supply). Such a feed may differ from that used by the fire department. Regardless of the type of supply, the sprinkler system is equipped with a main pipeline that enters the building to supply water to the riser. Valves, instrumentation and, preferably, an alarm device are connected to the riser to provide an audible signal when the system is activated. A series of pipes extending along the entire length of the fire compartment of the building are usually horizontally located downstream of the riser. Other risers may provide power from distribution networks to systems in adjacent fire compartments. The sprinkler system can be made in various configurations. In a water-filled system, used, for example, in buildings with heated rooms for branch pipes, all the pipes in the system contain fire extinguishing liquid, such as water, for immediate spraying through any activated sprinkler. In a dry pipe system used, for example, in unheated areas, areas exposed to cold, or areas where water leakage or an unintentional flow of water are usually undesirable or unacceptable, such as in rented living quarters when the system is in standby or inactive condition, in pipes, risers and main pipelines, branches and other distribution pipes of the fire protection system may be compressed dry gas (air, nitrogen or mixtures thereof). A valve is used to separate the pipes containing the water. When the heat from the fire activates the sprinkler, the gas exits the branches and the valve for dry pipes is activated or activated; water enters the branches, and the fire is extinguished, as the sprinkler sprays water.

One type of hydraulic control valve used to separate gas-filled pipes and liquid-filled pipes is a diaphragm valve or a diaphragm type valve, such as that described in US Pat. No. 8,616,234, entitled "Systems and Methods of Operating a Hydraulic Control Valve," or as described in the TFP 1315 specification published by Tyco Fire Products, entitled “Diaphragm Type Model DV-5 Drain Valve, DN40 - DN200 (1-1 / 2 '' - 8 ''), Drain System -“ Dry Pilot Launch ”( March 2004) (hereinafter “TFP1315”), in the TFP 1310 specification published by Tyco Fire Products, under the name “Orifice plate type DV-5 deluge valve, DN40 - DN200 (1-1 / 2 '' - 8 '' ), The deluge system is a “wet pilot launch” (March 2004) (hereinafter “TFP1310”), in the TFP 1320 specification published by Tyco Fire Products, under the name “Diaphragm type DV-5 deluge valve, DN40 - DN200 (1-1 / 2 '' - 8``), Drencher system - electrical activation ”(March 2004) (hereinafter“ TFP1320 ”), each of which is incorporated in its entirety by reference. To control the fluid flow between the inlet and the outlet and the corresponding wet and dry parts of the system, an internal diaphragm element is used in the control valve, having a sealed position and an open position to control the flow of fluid passing through the valve in order to shut off or pass the flow accordingly fluid flowing from the wet part of the system to the dry part of the system. The position of the diaphragm is controlled by the pressure of the fluid acting on the internal element of the diaphragm. The fluid pressure is controlled using various components that respond to the state of the system.

In the valve actuator assembly 10 according to one embodiment, the second channel 36b of the valve actuator 30 may be connected to a sprinkler hydraulic start system (not shown). The fluid pressure in the hydraulic start-up sprinkler system keeps the valve actuator ready. When the hydraulic start-up sprinklers are triggered in response to a fire and the fluid pressure in the hydraulic start-up sprinkler system is relieved, the reduced fluid pressure allows the valve actuator 30 to operate and transition to an activated state.

In FIG. 4A shows a preferred double-lock adjustment module 80a, which preferably comprises a pneumatic start actuator 82, a low pressure switch 84, a pressure gauge 86, and preferably a normally closed electronically controlled solenoid valve 88 interconnected by appropriate pipes and fittings for connection to the base node 10 of the valve and valve actuator.

In particular, the preferred electrical adjustment module 80c may comprise a connection 89 for connecting the electronically controlled solenoid valve 88 to the second channel 36b and the drain line or channel 87 for bringing the electromagnetic valve 88 into fluid communication with the dropping funnel 60 and the associated drain line. Electronically controlled solenoid valve 88 is preferably interconnected with an electronic detection system, such as, for example, a smoke or heat detector and / or an associated fire extinguishing control panel. In FIG. 6B shows a preferred assembly of the hydraulic control valve and valve actuator 10c with a preferred electrical adjustment module 80c connected to the second drive channel 36b.

The preferred valve actuator 30 preferably provides automatic and manual activation of the control valve 20 and the return of the control valve 20 to the standby state. In addition, by the preferred control: the valve actuator 30 adjusts, controls, and regulates the operation of the control valve 20 to put the fire protection system in an inactive state of alert and control the fire protection system to suppress fire. In FIG. 7A, 7B are schematic views of a fire protection system 100 in an inactive ready state and an activated state, respectively. As shown, the fire protection system 100 comprises a pipe system 100a for supplying a liquid, such as, for example, water to a sprinkler pipe system 100b, connected together via, preferably, a hydraulic control valve assembly 10 and a valve actuator according to a preferred embodiment of the invention. The fire sprinkler pipe system 100 shown in FIG. 7A and 7B is an illustrative embodiment of a dual-lock pre-emptive sprinkler system in which the sprinkler system uses automatic sprinklers 104 connected to a piping system 100b containing air or other pressurized compressed gas with an auxiliary detection system. The shown detection system comprises one or more detectors 106 for detecting fire, such as a smoke or heat detector 106, installed in the same area as the sprinklers 104. For the normally closed solenoid valve 88 to be electronically controlled in response to the detection by the detectors 106, the detectors 106 are preferably interconnected to the electronically controlled solenoid valve 88 of the preferred automatic control device 80a by the fire extinguishing control panel 108. The second detection system includes a reduced air pressure detection system that can detect an open or activated sprinkler 104. The pneumatic start actuator 82 of the preferred automatic control device 80a can function as a reduced air pressure detector by triggering when it detects a decrease in air pressure below a threshold value. For the dual-lock pre-emptive system shown, the preferred valve and valve actuator assembly 10a is activated when it is in a ready or waiting state, allowing water to flow into the sprinkler protection system 100b when both detectors 106, 82 of the preferred automatic control device 80a and the preferred actuator 30 are triggered valve.

Again, the preferred valve actuator 30 preferably provides automatic and manual activation of the control valve 20 and the return of the control valve 20 to the standby state. More specifically, FIG. 2A, 2B, 3A in combination with FIG. 7A, 7B, a preferred method of operating the valve actuator 30 preferably includes establishing a standby state of the valve actuator 30 by positioning the sealing member 35 in contact with the preferred valve seats 33a, 33b and providing fluid pressure from the preferred common or fourth channel 36d to the chamber 34 on the first side of the sealing element 35 and into the channel on the second side of the sealing element. In one preferred embodiment of the method, water escapes from the sprinkler pipe system 100b or is otherwise drained by the preferred automatic fire protection sprinklers 104 in an inactive state. Compressed gas, such as, for example, compressed air, via connection 83 is preferably supplied via a preferred double-blocking adjustment module 80a. The adjustment module 80a is preferably connected to at least one middle channel 28b, 28d of the hydraulic control valve for filling the sprinkler line 100b with compressed gas. The compressed gas pressure allows the pneumatic start actuator 82 to be closed, and the electronically controlled solenoid valve 88 returns to its normally closed position.

To return the preferred valve assembly 10 and valve actuator, water from the fluid supply pipe system 100a is supplied to the first channel 36a and the inner chamber 34 of the preferred actuator 30 and to the valve chamber 24 of the hydraulic control valve 20 through a common or fourth channel 36d. To return the valve diaphragm 26 of the preferred hydraulic control valve 20 to its sealed position, the preferred manual reset device 38 is preferably pressed or actuated to move the sealing element 35 to its sealed position in contact with the first and second actuator seats 33a, 33b. An increase in fluid pressure in the valve chamber 24 brings the valve diaphragm 26 to its sealed position, thereby closing the hydraulic channel 22 and preventing fluid communication between the hydraulic pipe system 100a and the sprinkler pipe system 100b to increase the pressure of the compressed air to its pressure level standby in the sprinkler pipe system 100b. A preferred tap water control valve 102 is open to supply water to the hydraulic control valve inlet 22a, the drain valve of the main line is closed and the pressure in the fluid pipe system 100a rises to its standby state to establish the system 100 and the preferred valve assembly 10a and drive the valve to standby or standby.

When the preferred system is ready, the system is ready to suppress fire. For a preferred dual-lock system, preferred heat or smoke detectors 106 are connected to a fire control panel 108, which is coupled to a preferred electronically controlled solenoid valve 88. When there is a sufficient level of smoke or heat, a normally open solenoid valve 88 opens to relieve fluid pressure from the sealing element 35 in the valve actuator 30, allowing it to move, switch, or move from the sealed position to its open position, thereby establishing a fluid communication between the valve chamber 24 and the valve inner chamber 34. If there is a sufficient level of heat, one or more sprinklers 104 are activated to relieve the pressure of the compressed gas from the sprinkler pipe system 100b. The pressure reduction of the compressed gas in the pipe system 100b preferably drives or opens the pneumatic start-up drive and allows fluid to be supplied and discharged from the inner chamber 34 at a faster rate than that supplied to the inner chamber 34 through a common channel 36d. Thus, the sealing element 35 of the actuator 30 moves to its open position and the pressure of the fluid in the valve chamber 24 decreases as the fluid is supplied from the valve chamber 24 and exits the preferred adjustment module 80a and the drain line 39a through the third channel 36c of the actuator 30. As the fluid pressure in the valve chamber 24 decreases, the valve diaphragm 26 moves from its sealed position to its open position to open the internal flow channel 22 and establish a fluid communication between the pipeline 100a system liquid supply pipe 100b and the sprinkler system. Water can fill the sprinkler pipe system 100b and flow out of the activated sprinklers 100a to suppress fire. Water flowing through the open inner channel 22 of the hydraulic control valve 20 preferably also flows from the middle channel 28a and the intermediate chamber 27 to provide an audio signal from an associated alarm system.

The control and operation of the preferred valve and actuator assembly 10 can alternatively be accomplished by modifying an automatic control device connected to the second channel 36b of the valve actuator 30. In particular, the number of adjustment components can be reduced by connecting any of the pneumatic or electrical adjustment module 80b, 80c described above. The pneumatic or electrical control modules 80b, 80c only provide for locking the actuation or actuation of the valve actuator 30 and the opening of the hydraulic control valve 20 as described above. For the pneumatic adjustment module 80b, the pneumatic start actuator detects a decrease in pressure in the sprinkler pipe under pressure, which indicates the actuation of the sprinkler 104, and is triggered in response to actuate the actuator 30. The electrical adjustment module 80c after receiving a detection signal from the heat / smoke detectors 106 preferably, through the fire extinguishing control panel 108, opens from its normally closed position to actuate the valve actuator 30.

System 100 can be further modified by modifying the sprinkler piping system to provide a sprinkler piping system in which sprinklers 104 are always open. For such a system, an automatic control device connected to the second channel 36b of the valve actuator 30 can operate both with a sprinkler hydraulic start system and a pneumatic start. In such a system, the activation of pilot sprinklers reduces the pressure of the fluid on the valve actuator sealing member 35, enabling it to switch and operate as previously described. In the case of a hydraulic start-up system, the start-up system is preferably directly connected to the second channel 36b of the valve actuator 30. For a pneumatic start actuated sprinkler system, the system is preferably connected to the second channel of the valve actuator 30 by means of a pneumatic adjustment module 80b. In another alternative embodiment, in which the sprinklers 104 of the sprinkler piping system are always open, the operation of the hydraulic control valve assembly 10c and the valve actuator can be disabled, preferably by connecting the electronic control module 80c to the second channel 36b of the valve actuator 30, and connecting to respective detectors 106 heat / smoke, to control the automatic operation of the valve actuator 30 in the manner described above.
