摘要： A flow control device has a body having a fluid holding chamber and an inlet port and two outlet ports which are adapted to removably receive valve cartridges. Each valve cartridge has a body having an inlet, an outlet and a fluid flow passageway extending therebetween. A collapsible tubing is mounted in the fluid flow passageway of the valve cartridge body. A piston movably mounted in the fluid flow passageway in the valve cartridge's body is moved into and withdrawn from the inlet of the collapsible tubing to selectively block and unblock the inlet of the collapsible tubing. The blocking of the inlet of the collapsible tubing causes a pressure decrease in the collapsible tubing downstream of the inlet which causes fluid pressure in the fluid flow passageway surrounding the collapsible tubing to collapse a portion of the collapsible tubing around the piston to further block fluid flow through the collapsible tubing. Valve cartridges are selectively provided in the inlet and output ports of the body of the flow control device to configure the flow control device for particular applications.

摘要： A flow control device, such as a valve, has a body with two portions which define two valve chambers, an inlet, which is coupled to a source of pressurized fluid and which opens into one of the valve chambers, and an outlet coupled to downstream devices, such as sprinkler heads, and which opens into the other valve chamber. A piece of collapsible tubing couples the two valve chambers. A shaft extends into the valve and is provided with a mechanism for pinching the collapsible tubing shut which causes the collapsible tubing to collapse due to the pressure exerted on its exterior by the pressurized fluid surrounding it. A coil spring is attached to the shaft and the valve body. When the valve is closed, i.e., the collapsible tubing collapsed, the coil spring is biased to cause the shaft to rotate if released. The shaft is prevented from rotating by a fusible link. When the temperature to which the valve is exposed reaches or exceeds a predetermined temperature, the fusible link melts. This releases the shaft for rotation and the coil spring rotates the shaft which unpinches the collapsible tubing. This permits the collapsible tubing to uncollapse, thus opening the valve.

摘要： A flow control device, such as a valve, has a valve body which has a fluid holding chamber therein. An inlet in the valve body couples the chamber to a source of pressurized fluid. An outlet in the valve body couples the chamber to downstream devices such as sprinkler heads. The outlet has an outlet opening which opens to the valve chamber. A collapsible tubing is sealingly attached at a first end to the outlet opening. The collapsible tubing has an opposite end which extends into the chamber. The opposite end of the collapsible tubing has an inlet which opens into the chamber. A mechanism is provided for blocking and unblocking the inlet of the opposite end of the collapsible tubing to cause the collapsible tubing to collapse and uncollapse to block and unblock fluid flow from the chamber through the outlet. The mechanism has a piston for insertion into and withdrawal from the inlet of the collapsible tubing to block and unblock the inlet. When the piston is inserted into the inlet of the collapsible tubing, the collapsible tubing collapses around the piston to block fluid flow from the chamber through the outlet. However, the collapsible tubing is not "pinched shut" and thus does not take on a set "pinched shut" shape. Thus, when the piston is withdrawn from the inlet, the collapsible tubing uncollapses immediately permitting fluid to flow without delay from the chamber through the outlet.

摘要： A flow control device has a body with side walls which define a fluid holding chamber, an inlet for allowing fluid to enter the chamber, and at least one outlet for allowing fluid to exit the chamber. A length of collapsible tubing is sealingly attached to each outlet and extends into the fluid holding chamber. A mechanical device is provided for selecting collapsing the tubing at a point which is spaced apart from the side walls of the chamber. When the tubing is collapsed at this point, the downstream pressure in the outlet decreases and the pressure of the fluid in the chamber causes the tubing between the location of the mechanical device and the side walls to collapse. The tubing is formed from a material having a durometer hardness rating selected on the basis of a fluid characteristic or on the basis of a characteristic of particle carried in the fluid. In the latter case, the tubing is selected to the soft enough to encapsulate and seal around particles in the collapsed seal area of the tubing. To open the valve, the mechanical device releases the tubing and the pressure of the fluid in the chamber causes the tubing to return to an uncollapsed state. One embodiment of the device has an arrangement for automatically opening the outlets when the temperature of the body increases beyond a predetermined level.
