Abstract
The invention relates to the field of pressure pipeline parts, in particular to a check valve of a fully closed heater. The check valve of the fully closed heater comprises a three-way upper valve body (201), a valve flap door (202), a valve flap root (203), a valve flap membrane (204) and a lower valve body (205). The check valve is characterized in that the three-way upper valve body (201) and the lower valve body (205) adopt screw joint for forming a valve body cavity, a port of the thickened upper valve body (201) in the valve body cavity serves as the valve flap door (202) of the valve flap membrane (204), and the valve flap root (203) is implanted into a preset hole position at the screw joint part of the three-way upper valve body (201) and the lower valve body (205).
Description
Technical field
The present invention relates to the safety check valve in the field of pressurized container, particularly a kind of totally-enclosed heater.
Background technique
The medium inlet of totally-enclosed heater must be provided with a control gear.This control gear can be manual, and also can adopt is automatically, but manually control can not be realized in some position of some machine.For example, the water system of drinking-water drink just must adopt water inlet designing requirement automatically, and the safety check valve just can have been taken on the machine task of water inlet automatically in this case.
Summary of the invention
The present invention's purpose is exactly to disclose a kind of valve that is used for the automatic check valve of totally-enclosed heater to society, and this safety check valve arrangement is simple, can directly insert in the pipeline and use.
A kind of safety check of totally-enclosed heater comprises: Three way type upper valve body (201), flap door (202), flap root (203), flap film (204), following valve body (205).It is characterized in that: described Three way type upper valve body (201) adopts Luo to close with following valve body (205), form the valve body chamber, the internally upset upper valve body in valve body chamber (201) port serves as the flap door (202) of flap film (204), and flap root (203) is implanted Three way type upper valve body (201) and closed in the portion preset holes position with following valve body (205) Luo.
The upper valve body (201) of the safety check valve of described totally-enclosed heater is the structure of threeway shape; The lower end mouth that described threeway shape upper valve body (201) and upper valve body (205) Luo close, its wall thickness is obviously greater than other two ports, and lower end mouth is served as the flap door (202) of flap film (204).
The following valve body (205) of the safety check valve of described totally-enclosed heater is characterized in that: described valve body (205) down can be regarded the association of large and small two hollow circular cylinders as, and described little hollow circuit cylinder is used to connect other parts; Described big hollow circuit cylinder and Three way type upper valve body (201) Luo close the valve chamber of formation safety check valve.
The flap film (204) of the safety check valve of described totally-enclosed heater is characterized in that: described flap film (204) is laminar, makes of flexible material, and being laminar flap film (204) is the molding and forming of one with flap root (203).
The flap root (203) of the safety check valve of described totally-enclosed heater is characterized in that: described flap root (203) is implanted Three way type upper valve body (201) and is closed in the portion preset holes position with following valve body (205) Luo, and flap root (203) and flap film (204) are the structure of " L " shape.
Description of drawings
Accompanying drawing 1 is safety check valve arrangement schematic representation of 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, upper valve body (101), valve spring (102), valve ball (103), valve ball seat (104) Three way type; Safety check 02, Three way type upper valve body (201), flap door (202), flap root (203), flap film (204), the following totally-enclosed heater 03 of valve body (205) and output switch 04.
Describe the present invention in detail below in conjunction with accompanying drawing:
As shown in Figure 1, a kind of safety check of totally-enclosed heater comprises: Three way type upper valve body (201), flap door (202), flap root (203), flap film (204), following valve body (205).It is characterized in that: described Three way type upper valve body (201) adopts Luo to close with following valve body (205), form the valve body chamber, the internally upset upper valve body in valve body chamber (201) port serves as the flap door (202) of flap film (204), and flap root (203) is implanted Three way type upper valve body (201) and closed in the portion preset holes position with following valve body (205) Luo.
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 began heating, heat medium must be for producing the phenomenon that heat is splashed and risen and steam takes place, along with the increase of heated pressure, flap film (204) is pressed on flap door (202), thereby plays the generation that heat medium can not reflux and prevent the warm phenomenon of string.
