Description
Technical field
The present invention relates to a kind of relief valve and use its boiler, especially relate to a kind of total head handover security valve gathering negative pressure, normal pressure and three kinds of functions of pressure-bearing and use its total head boiler.
Background technology
Boiler can be divided into following three kinds of form boilers according to the pressure in its stove:
1, bearing boiler；
Bearing boiler is exactly the boiler of our generally seen closed, and the pressure in its boiler both generally is greater than a normal atmosphere.Boiler circuit in boiler is made up of airtight container and pipeline, and is heated by flame, bears fluid pressure at work, belongs to special equipment.
2, normal-pressure boiler；
Normal-pressure boiler is exactly pressure-less boiler, refers to that in pot, water vapour gauge pressure is zero, the boiler namely run under local atmospheric pressure.
3, negative pressure (vacuum) boiler；
Negative pressure (vacuum) boiler is to form a subnormal ambient lower than atmospheric pressure state at the furnace interior closed, and by burning or alternate manner heating, produces the temperature steam lower than 100 DEG C.
Existing three class boilers include negative pressure (vacuum) boiler, normal pressure (without pressure) boiler and bearing boiler and use condition all relatively stringent, independent, and the division is clearly demarcated.Three class boilers have limitation, it is impossible to accomplish general.
The boiler sold on usual market can only realize one of above-mentioned three kinds of pressure patterns, it does not have any boiler can realize above-mentioned three kinds of pressure patterns or three kinds of pressure patterns are carried out free switching.
The invention discloses a kind of total head boiler, this total head boiler can be defined as: in pot, steam gauge pressure can be required to unrestricted choice according to user and realize the boiler of negative pressure (vacuum) boiler, normal pressure (without pressure) boiler, any pressure operation of bearing boiler.
Summary of the invention
The present invention devises a kind of total head handover security valve and uses its total head boiler, it solves the technical problem that the boiler being to sell on existing market can only realize one of above-mentioned three kinds of pressure patterns, it does not have any boiler can realize above-mentioned three kinds of pressure patterns or three kinds of pressure patterns are carried out free switching.
In order to solve the technical problem of above-mentioned existence, present invention employs below scheme:

Detailed description of the invention
Below in conjunction with Fig. 1 and Fig. 2, the present invention will be further described:
As it is shown in figure 1, a kind of total head boiler, this total head boiler realizes normal pressure, negative pressure and three kinds of pressure patterns of pressure-bearing and carries out free switching.
Its structure is as follows: total head boiler includes burner 1 and vaporium 2, and the port of export of burner 1 is provided with a condenser 11, and it is for carrying out heat exchange with flue gas.Burner 1 is connected with vaporium 2 and is heated by the water in vaporium 2 or be heated into steam.The arrival end of vaporium 2 is provided with stop valve 22, and the port of export of vaporium 2 is provided with water-supply valve 23.Vaporium 2 is provided with Pressure gauge 21 and total head handover security valve 3, and the normal pressure of vaporium 2, negative pressure and three kinds of pressure pattern switchings of pressure-bearing are controlled by total head handover security valve 3.
Total head boiler of the present invention, the feature of negative pressure (vacuum) boiler, normal pressure (without pressure) boiler and bearing boiler three class boiler well can be combined, realize containing functionally, can switch over easily as required, it is possible to realize three-in-one real unification.
As shown in Figure 2, total head handover security valve 3 includes upper cover plate 31, lower cover 32 and flange seat 34, total head handover security valve 3 is connected with vaporium 2 by flange seat 34, lower cover 32 is between upper cover plate 31 and flange seat 34, lower cover 32 covers on flange seat 34, a spring 35 is clamped between upper cover plate 31, lower cover 32, upper cover plate 31, lower cover 32 and flange seat 34 are provided with screw and are spirally connected by connecting bolt 33, and spacing and the elastic force of spring 35 between upper cover plate 31 and lower cover 32 are adjusted by connecting bolt 33.
Connecting bolt 33 is many, and is uniformly distributed along flange seat 34 circumference.
Being provided with a guide post 36 in the middle of spring 35, guide post 36 is spirally connected and is fixed on lower cover 32.The guide post 36 partial-length between upper cover plate 31 and lower cover 32 is adjustable.The purpose of this adjustment is in that: when being converted to bearing boiler, and the spacing between upper cover plate 31 and lower cover 32 reduces to increase the elastic force that spring 35 produces, thus the partial-length that guide post 36 is between upper cover plate 31 and lower cover 32 should also be as corresponding reduction.
The annular groove 37 for placing sealing ring it is provided with between lower cover 32 and flange seat 34.Annular groove 37 is positioned on flange seat 34.
The operation principle of total head boiler of the present invention is as follows:
When pressure in total head boiler is negative pressure, the upper cover plate 31 of total head handover security valve 3, lower cover 32 and spring 35 produce downward gravity, and with extraneous atmospheric pressure combined effect, flange seat 34 is sealed, the Pressure gauge 21 of total head boiler is shown as negative pressure；
When pressure in total head boiler is normal pressure, total head pot furnace pressure is equal to external atmospheric pressure, and flange seat 34 is sealed by the gravity by the upper cover plate 31 of total head handover security valve 3, lower cover 32 and spring 35, and the Pressure gauge 21 of total head boiler is shown as zero；
When pressure in total head boiler is pressure-bearing, it is rotated down connecting bolt 33 and reduces the spacing of upper cover plate 31 and lower cover 32 thus holddown spring 35, now total head handover security valve 3 produces downward power and includes the gravity of upper cover plate 31, lower cover 32 and spring 35 and spring 35 deformation produces to down spring, and the Pressure gauge 21 of total head boiler is shown as more than zero.
When total head Phase transformation boiler vaporium hypertonia is beyond safety value the calculating of downward force (this safety value produce according to described total head handover security valve 3); lower cover 32 is upspring along connecting bolt 33 and guide post 36 upward sliding, now from carrying out pressure release between lower cover 32 and flange seat 34 to protect total head boiler safety.
Need illustratively: the limited gravity that guide post 36 produces, when calculating pressure, it is possible to ignore.
The present invention has techniques below effect and economic effect:
1, the total head boiler concept that the present invention initiates；
2, total head boiler one-time investment of the present invention, obtains three kinds of type of furnaces；
3, total head boiler energy-saving environmental protection of the present invention；
4, total head boiler efficiency of the present invention is high；
5, total head boiler attendance of the present invention is convenient, easy to maintenance.
Above in conjunction with accompanying drawing, the present invention is carried out exemplary description; the realization of the obvious present invention is not subject to the restrictions described above; as long as have employed the various improvement that the design of the method for the present invention carries out with technical scheme; or the not improved design by the present invention and technical scheme directly apply to other occasion, all in protection scope of the present invention.
