Abstract
The utility model discloses an anti-explosion pressure release device of boiler, comprising a base pipe connected with the water jacket and body of the boiler. A pipe hoop is connected with the external opening of the base pipe; at least an anti-explosion pressure release piece is fixed by compression at the joint end face between the pipe loop and base pipe; the other end of the pipe loop is connected with a drainage pipe. During the operation, the utility model is arranged on the water jacket body of the boiler. When the pressure inside the water jacket of boiler reaches the alarming value, the anti-explosion pressure release piece arranged at the joint end face between the pipe loop and base pipe will be burst open and the pressure will be released fast. Meanwhile, the water gushed out of the water jacket of the boiler can be drained to outdoor or the sewer via the drainage pipe connected to the other end of the pipe loop. The utility model, with simple structure, low manufacturing cost and fast pressure release, results in no seeper indoor.
Description
Technical field
The utility model relates to a kind of the decompression explosion-proof device that is used to prevent the bursting of boilers, particularly boiler explosion-proof relief device.
Background technology
The bursting of boilers is the serious major accident of a kind of consequence, causes immeasurable loss often for personal life, property.In order to prevent the bursting of boilers, pressure-reducing valve generally all is installed on the boiler, when the boiler internal pressure was elevated to warning value, pressure-reducing valve just can fast decompression, prevented the boiler accident of blasting.But boiler pressure-reducing valve steam vent commonly used is too tiny, and not only exhaust decompression speed is slow, and is stopped up by foreign matter easily, and it is malfunctioning to cause reducing pressure.In addition, during the work of traditional boiler pressure-reducing valve, the water in the boiler can spray from pressure-reducing valve, and it is residing indoor to flow to boiler, causes indoor ponding, influences ordinary production.
Summary of the invention
The purpose of this utility model is to provide a kind of boiler explosion-proof relief device, and is not only simple in structure, cheap for manufacturing cost, and decompression rate is fast, can not cause indoor ponding.
The purpose of this utility model is achieved in that a kind of boiler explosion-proof relief device, this pressure relief device comprises a pedestal tube that is connected with the boiler water jacket furnace, connecting pipe collar on the outer end mouth of pipe of pedestal tube, be compression fit at least one explosion-proof relief sheet is installed in the contacted end that is connected of pipe collar and pedestal tube, the other end of pipe collar is connecting drainpipe.
When the utility model uses, it is installed on the boiler water jacket furnace, when boiler water jacket internal pressure reaches warning value, can break through and be installed in pipe collar is connected the end with pedestal tube explosion-proof relief sheet, rapidly pressure release, can drain into outdoor by the drainpipe that connects the pipe collar other end by the water that sprays in the boiler water jacket furnace simultaneously or sewer in.The utility model is not only simple in structure, and is cheap for manufacturing cost, and decompression rate is fast, can not cause indoor ponding.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a part section structural representation of the present utility model;
Fig. 2 is the part section structural representation of the another kind of embodiment of the utility model.
The specific embodiment
A kind of boiler explosion-proof relief device, as shown in Figure 1, this pressure relief device comprises a pedestal tube 1 that is connected with the boiler water jacket furnace, connecting pipe collar 2 on the outer end mouth of pipe of pedestal tube 1, be compression fit at least one explosion-proof relief sheet 3 is installed in the contacted end that is connected of pipe collar 2 and pedestal tube 1, the other end of pipe collar 2 is connecting drainpipe 4.As shown in Figure 2, have an annular shoulder block in the outer end mouth of pipe of pedestal tube 1, have internal thread on the outer end mouth of pipe internal perisporium of pedestal tube 1, pipe collar 2 is installed in explosion-proof relief sheet 3 compression fit by being threaded the mouth of pipe shoulder block place, outer end of pedestal tube 1 with pedestal tube 1.As shown in Figure 1, has an annular shoulder block in the pipe collar 2, have external screw thread on the outer end mouth of pipe periphery wall of pedestal tube 1, the outer end mouth of pipe external diameter of pedestal tube 1 equals the internal diameter of pipe collar 2, and pedestal tube 1 and pipe collar 2 are installed in annular shoulder block place in the pipe collar 2 by being threaded with explosion-proof relief sheet 3 compression fit.As shown in Figure 1 and Figure 2, according to the different sizes of boiler tonnage, the number of explosion-proof relief sheet 3 can overlapped arrangement be installed the distance installation that also can be spaced from each other certain for two or more.Explosion-proof relief sheet 3 is sheet rubber or low-melting alloy sheet, as adopting the low-melting alloy that is made of metal materials such as bismuth, cadmium or lead.The cross section of explosion-proof relief sheet 3 is font or I-shaped.
