A pressure regulating system having a tamper-proof safety feature. A pair of seats are mounted to an annular pipe. A first bleed pipe, with a fixed restriction, extends from an inlet conduit to a first chamber. The first chamber is separated from a second chamber by a second diaphragm. A second bleed pipe extends from the second chamber to an outlet pipe. A bleed off mechanism is sealed within the outlet conduit and includes a compressible bellows. When compressed, which occurs when a predetermined pressure level is attained in the outlet conduit, a third seat is moved out of sealing relation with the outlet conduit and the first chamber. This creates an imbalance of the pressures in the chambers that leads to the pair of seats being moved to seal off apertures in the inlet conduit, thereby inhibiting flow into the outlet conduit.

A system including pluralities of tubular lengths and T-connectors couplable with said lengths in a package for assemblage into an orthogonal frame of width, length and depth not in excess of 24 inches, 80 inches and 5&#xbd; inch, respectively, for securement to one of a planar wall and planar door surface.

A lockable valve having features which impede unauthorized removal of the valve from a conduit to which the valve is connected. The housing of the valve has a passageway. A valve element is movably mounted to the housing for occluding the passageway. A structure operatively associated with the valve element impedes disengagement of the valve from the conduit when the valve element is in a first position. Preferably, the housing of the valve is attachable to the conduit by a fitting which is movably mounted to the housing and such fitting is accessible only through the passageway of the housing when the valve is mounted to a conduit. When the valve element occludes the passageway, it blocks access to the fitting and hence serves as part of the disengagement-impeding structure. The valve may include lugs for connecting the fitting to the housing for movement therewith when valve element is in a second position. If such lugs are provided, the valve can be disengaged from the conduit by moving the valve element to the second position and then moving the housing.

Valve with anti-removal feature

A pipe cutter for cutting the wall of a pipe from within the bore of the pipe. The cutter includes a blade and mechanisms for supporting the blade within the pipe to be cut, urging the blade outwardly of the pipe to engage it with the pipe wall and moving the blade relative to the pipe so that the blade cuts the wall. The cutter may include an expansible gripper assembly for engaging the pipe wall to retain the blade against movement axially of the pipe during the cutting operation. The gripper assembly is preferably operative upon operation of the blade movement mechanism. The blade may be a circular saw, the blade movement mechanism may be arranged to move the saw in orbital fashion around the axis of the pipe and the gripper assembly may be connected to the blade so that the gripper assembly prevents rotation of the saw about its axis during the cutting operation. When this arrangement is utilized, all of the teeth of the saw are successively engaged with the pipe wall.

Pipe cutter

A shield is rotatably mounted to a threaded element of the closure on an axis coincident with the axis of the threaded element, so that the shield impedes access to the threaded element. The shield can be removed from the threaded element or connected to the threaded element only upon actuation of the closure by an appropriate key. Absent such actuation, the threaded element cannot be rotated for disengagement from the conduit by rotating the shield. The closure is protected against attempts to disengage it from the conduit by bonding the shield to the threaded element with an adhesive and rotating the shield.
