Abstract
The utility model relates to the pressure vessel field, especially to a flow evacuating relief valve of a totally-enclosed heater, which comprises an upper valve body (101), a valve spring (102), a valve ball (103), a valve ball cup (104) and a tee joint type lower valve body (105). The valve is characterized in that: the upper valve body (101) and the lower valve body (105) of the flow evacuating relief valve are screwed together to form a valve body cavity; The screw portion of the lower valve body (105) and the upper valve body (101) is used as the valve ball cup (104) of the valve ball (103); and the valve ball (103) is compressed on the valve ball cup (104) by the valve spring (102).
Description
Technical field
The present invention relates to the thin stream reduction valve in the field of pressurized container, particularly a kind of totally-enclosed heater.
Background technique
Totally-enclosed heater can produce certain pressure, under pressure surpasses the situation of design objective, the releive pressure of heater of decompressor must be arranged, and ensures the safe operation of machine.For example, for solving the barrelled water secondary pollution problem, the packed water drink machine of releasing has recently just adopted the pattern of totally-enclosed heating drinking-water, dredges the bodyguard that the stream reduction valve has been taken on the machine safe operation under this totally-enclosed heating state.
Summary of the invention
The present invention's purpose is exactly to disclose a kind of valve of dredging the stream decompression automatically that is used for totally-enclosed heater to society, and it is simple that this dredges the stream structure of relief pressure valve, can directly insert pipeline or independent the use.
A kind of thin stream reduction valve of totally-enclosed heater comprises: valve body (105) under upper valve body (101), valve spring (102), valve ball (103), valve ball seat (104) Three way type.It is characterized in that: the upper valve body of described thin stream reduction valve (101) adopts with following valve body (105) and screws togather, form the valve body chamber, the screwing part of following valve body (105) and upper valve body (101), the valve ball seat (104) that serves as valve ball (103), valve spring (102) press valve ball (103) on valve ball seat (104).
The structure of the upper valve body (101) of the thin stream reduction valve of described totally-enclosed heater can be regarded the association of large and small two hollow circular cylinders as; Described little hollow circuit cylinder is used to connect other parts; Described big hollow circuit cylinder screws togather with following valve body (105), forms and dredges the valve chamber that flows reduction valve.
The following valve body (105) of the thin stream reduction valve of described totally-enclosed heater is the structure of threeway shape; The wall thickness at the upper end-hole position that valve body (105) and upper valve body (101) screw togather under the described threeway shape is obviously greater than other two ports, and the upper end-hole of heavy wall forms the valve ball seat (104) of valve ball (103).
The valve spring (102) of the thin stream reduction valve of described totally-enclosed heater is taper, be commonly called as " awl spring ", make of stainless steel material, the base portion supports of " awl " then withstands on the valve ball (103) pinnacle of a pagoda of " awl " on the step that inboard large and small two hollow circular cylinders of upper valve body (101) form.
The valve ball (103) of the thin stream reduction valve of described totally-enclosed heater is the stainless steel ball of a spherical shape, by described valve spring (102) roof pressure in valve ball seat (104) on.
Description of drawings
Accompanying drawing 1 is dredged stream structure of relief pressure valve schematic representation for the present invention.
Accompanying drawing 2 is the embodiments of the invention schematic representation.
Embodiment
The mark title of accompanying drawing 1 is: valve body (105) under upper valve body (101), valve spring (102), valve ball (103), valve ball seat (104) Three way type.
The mark title of accompanying drawing 2 is: dredge valve body (105) under stream reduction valve 01, safety check 02, totally-enclosed heater 03, upper valve body (101), valve spring (102), valve ball (103), valve ball seat (104) Three way type, Three way type upper valve body (201), flap door (202), flap root (203), flap film (204), following valve body (205).
Describe the present invention in detail below in conjunction with accompanying drawing:
As shown in Figure 1, a kind of thin stream reduction valve of totally-enclosed heater comprises: valve body (105) under upper valve body (101), valve spring (102), valve ball (103), valve ball seat (104) Three way type.Valve body (105) screws togather and forms the valve chamber of dredging the stream reduction valve under described upper valve body (101) and the Three way type; In the described valve chamber, the valve ball seat (104) of valve ball (103) is served as in the upper end of valve body (105) under the Three way type of having thickeied, and is mitre valve spring (102) and presses valve ball (103) on valve ball seat (104).
As shown in Figure 2, the thin stream reduction valve 01 among the figure, safety check 02, totally-enclosed heater 03 and output switch 04 have constituted a typical totally-enclosed heating circuit.Heat medium enters from the Three way type upper valve body (201) of safety check 02, and stream Jing Fabanmen (202), flap film (204), following valve body (205) are implemented heating by totally-enclosed heater 03; Be positioned at the thin stream reduction valve 01 at totally-enclosed heater 03 top, an end of valve body under its Three way type (105) and the outlet of totally-enclosed heater 03 are joined, and the other end and medium output switch 04 are connected; Dredging the upper valve body (101) of stream reduction valve 01 and (201) ports of Three way type upper valve body of safety check 02 is connected.
Further, after totally-enclosed heater 03 begins heating, heat medium must be for producing the phenomenon that heat is splashed and risen and steam takes place, when heated pressure during greater than design pressure, the steam of heat medium or generation can back down valve ball (103) automatically, realize decompression automatically, to ensure the safe operation of totally-enclosed heater 03.
