Abstract
The utility model relates to a vacuum hot water boiler's explosion rupture disk device, including mounting flange (4), accompany in the middle of mounting flange (4) rupture membrane (5), rupture membrane (5) are supported by orifice plate piece (6), and the top of rupture membrane (5) has sharp object (3), and the point of sharp object (3) and the distance between rupture membrane (5) are within high scope is heaved to rupture membrane (5) pressurized. During the superpressure, the back is heaved in rupture membrane (5) in the boiler, and sharp object (3) puncture it, play the effect of pressure release, improve its security.
Description
Technical field
This utility model relates to a kind of explosion rupture disk device, the explosion rupture disk device of a kind of vacuum hot water boiler.
Background technology
The full name of vacuum boiler is called phase change vacuum boiler.Vacuum boiler is the vacuum environment of furnace interior one negative pressure of formation in closing, fills heat medium water in body, by burning or alternate manner heating heat medium water, then is evaporated by heat medium water, condenses to heat exchanger, then is heated the water needing to heat by heat exchanger.Vacuum boiler passes through evacuation, forms a lower pressure environment almost without air, then utilizes water under low pressure (subatmospheric) low-temperature boiling to produce steam, and the principle exported by heat by soda pop condensation heat transfer mode is worked.Heat medium water in vacuum boiler is the high purity water through the special handling such as deoxidation, scale removal, once fill before dispatching from the factory, in the internal closed circulation of unit (vaporization → condense → vaporization) during use, do not increased, do not reduce, need not supplement or change within unit service life.
In the work process of vacuum hot water boiler, its vacuum chamber can produce certain pressure because of temperature rising, close down burner when pressure exceedes safety value, for avoiding vacuum chamber to explode because of hypertonia, need for this to be equipped with an explosion rupture disk device for vacuum hot water boiler.
Summary of the invention
Technical problem to be solved in the utility model is to provide the explosion rupture disk device of a kind of vacuum hot water boiler, this device provides an orifice plate sheet to be supported by rupture pressure disc relatively thin for material, rupture in order to avoid rupture pressure disc produces under vacuum kettle furnace pressure changes, this explosion rupture disk device includes mounting flange 4, mounting flange 4 is sandwiched between rupture pressure disc 5, rupture pressure disc 5 is supported by orifice plate sheet 6, there is sharp object 3 top of rupture pressure disc 5, and the distance between point and the rupture pressure disc 5 of sharp object 3 is within the scope of rupture pressure disc 5 pressurized bulge height.
Preferably, mounting flange 4 is circular.
Preferably, the two panels up and down of mounting flange 4 is fixed by bolt hole 1.
Preferably, sharp object 3 is fixed on mounting flange 4 by steel plate 8 and bolt 2.
Preferably, the point of sharp object 3 is relative with the center of annular mounting flange 4.
Preferably, orifice plate sheet 6 is a disk having some through holes.
Preferably, orifice plate sheet 6 is by the pipe walls support of pipe 7.

Detailed description of the invention
nullFig. 1 is the front view of vacuum hot water boiler explosion rupture disk device，Pipe 7 is connected with the vacuum chamber of vacuum hot water boiler，It is connected above mounting flange 4 at pipe，Mounting flange 4 is divided into upper and lower two panels，Fig. 2 we can see that, mounting flange 4 is for annular，Annulus is evenly distributed with four bolts hole 1，A steel plate 8 it is fixed with on flange above，Steel plate 8 is while being fixed on flange 4，The other end is connected with sharp object 3 by bolt 2，The step that is shaped as of steel plate 8 is preferred，While being fixed on mounting flange 4 under step，Above while stretching at circle ring center，Steel plate 8 is above while there is a bolt 2 position relative with the center of annulus，Bolt 2 connects below a sharp object 3，Sharp object can be nail or thin blade etc.，Below sharp object 3，Sharp proximity from sharp object 3，It it is rupture pressure disc 5，Rupture pressure disc 5 is gripped by the two panels up and down of mounting flange 4，Rupture pressure disc 5 generally silica gel material，Other rupture pressure disc materials are also within the range of choice，Rupture pressure disc 5 is supported by orifice plate sheet 6，Orifice plate sheet 6 is a disk having some through holes，Made by on-deformable material，Pipe walls support by pipe 7.
When the pressure in vacuum hot water boiler is transferred to malleation by negative pressure, rupture pressure disc 5 is upwards heaved, and encounters the sharp object 3 of top, plays the effect of pressure release aerofluxus, and the distance between point and the rupture pressure disc 5 of sharp object 3 is within the scope of rupture pressure disc 5 bulge height.
It is above one of embodiment of the present utility model, for those skilled in the art, does not spend performing creative labour, multiple change can be done on the basis of above-described embodiment, be capable of the purpose of this utility model equally.But, this change obviously should be in the protection domain of claims of the present utility model.
