The safety device is reusable actions to relieve the pressure from the tank

 

The invention relates to safety devices reusable actions to relieve the pressure from the container, such as containers for storage, distribution and transportation of beer. The safety device is reusable actions to relieve the pressure from the tank contains a piston, seal, and supporting elements. When this plunger is made spring loaded and covered by the supporting elements made in the form of a collet. The outer surface of the petals collets have protrusions that interact with flange nuts. Nut is installed in the socket, in which the bore communicating with the tabs petals collets after activation. With the inner surface of the petals collets interact with the conical surface of the piston. The safety device allows multiple use and increases its safety in operation. 1 Il.

The invention relates to safety devices reusable actions for pressure relief safety containers, such as containers for storage, distribution and transportation of beer.

Known safety valve single action, comprising a housing, a piston with a seal areas and danger to operating personnel in the operation of vessels, under the pressure.

The objective of the proposed technical solution is the reusability of use and safety in operation.

The problem is solved in that the pressure relief device containing the piston, seal, and supporting elements, the piston is made spring loaded and covered by the supporting elements made in the form of a collet, the outer surface of the petals which have protrusions that interact with collar nut, which is installed in the socket, in which the bore, also interacting with the tabs petals collet after the operation, with the inner surface of the petals interact with the conical surface of the piston.

The drawing shows the safety device reusable actions, embedded in a gas-discharge valve.

The safety device is placed in the drain pipe 1 and consists of a spring piston 2 with a gasket 3, the support elements made in the form of the petals of the collet 4, the outer surfaces of which have protrusions 5, interacting with the flange 6, is made on the nut 7, which is installed in the pipe 1, having a bore 8 communicating with the protrusions 5 lepestkami interacts with the inner surfaces of the petals of the collet 4, the piston 3 is spring-loaded by means of a spring 10.

Collet 4 with its petals with the protrusions 5 is engaged with the flange 6 of the nut 7. A spring-loaded piston 3 of its conical surface 9 restricts the movement of the petals of the collet 4 in the radial direction. When loosening the nut 7 axial force from the tightening of the collet 4 is transmitted to the conical surface 9 of the piston 3, creating the friction needed to hold the piston 3 from moving when the pressure in the tank.

With increasing pressure in the vessel, when the frictional force on the conical surface 9 of the piston 3 will be less effort from the pressure on its sealing area, the piston 3 moves, compressing the spring 10, and the petals of the collet 4 will SAG and will be released from engagement with the flange 6 of the nut 7, after which the collet 4 together with the piston 3 moves from the pressure and kept from falling out by the interaction of the protrusions 5 petals collet 4 and the end face of the bore 8 of the nozzle 1.

The proposed solution will allow you to use reusable safety device and to increase its safety in operation.

The invention relates to a device for limiting the pressure

Hydraulic valve // 2068520

Cutoff device // 2322627

FIELD: valving systems.

SUBSTANCE: cutoff device comprises push button, lid, and housing. The housing receives diaphragm, check valve, spring, inlet and outlet openings. The first end of the rod of the diaphragm is rigidly connected with the check valve. The opposite end of the rod is connected with push button. The space of the rod provided with the push button is in communication with the outlet port through a passage. The spring permanently acts on the check valve thus permitting the inlet port of the housing to be cut from the outlet opening.

EFFECT: enhanced reliability.

FIELD: machine building.

SUBSTANCE: 3-way discharge valve is used on railroad transport, and is intended to discharge the compressed air from the brake cylinders with further their filling. The 3-way discharge valve contains a body, base, casing, main valves, pilot valves, main line connecting input cavity and a cavity of medium supply to an actuator, discharge mail line connecting the cavity of medium supply to the actuator and cavity of medium discharge to atmosphere, control main line. Between the input cavity and cavity of medium supply to the actuator a check valve is installed.

EFFECT: use of this 3-way discharge valve improves service life and safety of the railroad transport.
