Description
Technical field
The utility model relates to machinery equipment field more particularly to a kind of nozzles for attemperator.
Background technique
In many fields, such as thermoelectricity, petroleum, papermaking, chemical industry, metallurgy, steel, printing and dyeing, pharmacy field, require with
The needs that steam is power to meet production technology, however since vapor (steam) temperature is often excessively high, it is unable to meet production wanting for technique
It asks, influences normal use.Attemperator is just needed to carry out desuperheat to steam to meet the needs of production technology in this case.It is existing
Technology be that desuperheat is carried out to high-temperature steam by feed-regulating valve, the steaming in mixing duct is reduced by the principle of heat exchange
Stripping temperature.Nozzle is in attemperator for controlling the part of amount of water sprayed, including constant cross-section formula nozzle and the spray of section-variable formula
Two kinds of mouth.Section-variable formula nozzle is the nozzle for referring to adjust water spray area, the Chinese patent of Patent No. CN201944826
" steam attemperator with spring-adjustable umbrella-shaped atomizing nozzle " gives a kind of nozzle that amount of water sprayed is adjusted using spring cooperation plug
Fluid channel design in the side of nozzle chamber, is caused the rod piece for connecting plug very long, entire nozzle exists by structure, this nozzle
All there is biggish size, structure is also relative complex in terms of diameter and length；Biggish size makes the metered flow of the nozzle
Coefficient is larger, is difficult to apply the occasion less in some amount of water sprayed.
Summary of the invention
The technical problem to be solved by the present invention is to provide a kind of nozzles smaller, structure is simpler.
In order to solve the above technical problems, the technical solution adopted by the utility model is: a kind of section-variable formula nozzle, including
Cavity, motion bar and spring；
Cavity includes the upper cavity being sequentially communicated, middle cavity and lower chamber, and the internal diameter of middle cavity is less than upper cavity and cavity of resorption
The internal diameter of body is provided at least one groove passed through for fluid in upper cavity, and groove extends to bottom surface from the inner wall of upper cavity
And finally it is connected to middle cavity；
Motion bar includes spool and plug and convex shoulder structure positioned at spool both ends, spool from upper cavity, middle cavity and under
Cavity passes through, and plug gets lodged in lower chamber, and convex shoulder structure is located in upper cavity；The diameter of spool is less than the internal diameter of middle cavity；
For spring pocket on spool, the both ends of spring are respectively held against the bottom of convex shoulder structure and upper cavity；
When in use, cooling water enters back into cavity of resorption by cavity in the groove inflow of upper cavity to the nozzle of the utility model
Body, cooling water push plug by the pressure of itself, then go out from the eject slot of plug and lower chamber.
Specifically, the spring is disk spring.
Further, the plug is in truncated cone-shaped, and the opening of the lower chamber is provided with a circle inclined-plane.
Further, the convex shoulder structure is nut, and nut is threadedly coupled with spool.
The utility model has the advantages that the nozzle of the utility model is using the intracorporal groove of epicoele as the channel of cooling water, compared to biography
Additional cooling-water duct is arranged without the side in cavity for the nozzle of system, simplifies the structure of nozzle, reduces nozzle in length
Degree and radial size.
Detailed description of the invention
Fig. 1 is the schematic diagram of 1 nozzle of embodiment.
Fig. 2 is the part drawing of 1 cavity of embodiment.
Wherein: 1, upper cavity；11, groove；2, middle cavity；3, lower chamber；4, spool；5, plug；6, nut；7, spring.
Specific embodiment
The utility model is described in further detail With reference to embodiment.
Embodiment 1
As shown in Figure 1, the section-variable formula nozzle of the present embodiment, including cavity, motion bar and spring 7；
As shown in Fig. 2, cavity includes the upper cavity 1, middle cavity 2 and lower chamber 3 being sequentially communicated, the internal diameter of middle cavity 2 is small
In being provided with four grooves 11 passed through for fluid in the internal diameter of upper cavity 1 and lower chamber 3, upper cavity 1, groove 11 is from upper cavity
1 inner wall extends to bottom surface and is finally connected to middle cavity 2；
Motion bar includes spool 4 and plug 5 and nut 6 positioned at 4 both ends of spool, and spool 4 is from upper cavity 1,2 and of middle cavity
Lower chamber 3 passes through, and plug 5 gets lodged in lower chamber 3, and plug 5 is in truncated cone-shaped, and the opening of the lower chamber 3 is provided with a circle inclined-plane；
Nut 6 is located in upper cavity 1, and nut 6 is threadedly coupled with spool 4；The diameter of spool 4 is less than the internal diameter of middle cavity 2；
Spring 7 is disk spring, 7 sets of spring on spool 4, the both ends of spring 7 are respectively held against nut 6 and upper cavity 1
Bottom；
When in use, cooling water enters back into down the nozzle of the present embodiment by cavity 2 in the inflow of groove 11 of upper cavity 1
Cavity 3, cooling water push plug 5 by the pressure of itself, then go out from the eject slot on plug 5 and the inclined-plane of lower chamber 3；
Compared to traditional section-variable formula nozzle, the present embodiment jet size is smaller, and rated flow coefficient is sprayed close to constant cross-section formula
Mouth has very extensive applicability.
Although the embodiments of the present invention is illustrated in specification, these embodiments are intended only as mentioning
Show, should not limit the protection scope of the utility model.Various omissions are carried out in the range of not departing from the utility model aims, are set
It changes and change should be included in the protection scope of the utility model.
