Problems solved by technology

[0002] The check valves used for public flue or external wall direct discharge put forward higher requirements for the opening effect, fire performance and sealing effect of the check door panels, but the current check valves have many defects, such as , the non-return door panel rotates around the connecting shaft. Because the contact surface of the connecting shaft is large, it is easy to be stained with oil. During use, the non-return door panel is often stuck during the rotation process, so that only part of it can be opened, not all or can not be opened. Completely return to the position, thus affecting the ventilation effect and the effect of preventing smoke return in the same period of time; in addition, although the fire prevention device is installed, the structure is complicated, the production cost is high, and it is easy to fail, and the fire resistance performance is poor; at the same time, the odor of the flue The phenomenon happens from time to time, and the room is full of peculiar smell, which seriously affects the health of family members

Embodiment 1

[0037] like figure 1 and figure 2 As shown, the present invention discloses a fireproof check valve with an umbrella-shaped fireproof temperature sensing device, including a metal cylinder 1, a check door panel 2, an umbrella-shaped fireproof temperature sensing device, a metal check door frame 14 and a metal mounting seat 15 .

[0038] like Figure 4 As shown, the metal cylinder 1 includes an upper cylinder 101 and a lower cylinder 102 nested with each other. The upper cylinder 101 is provided with a bump 103, and the lower cylinder 102 is provided with an L-shaped groove 104 at a corresponding position. The cylinder body 102 is inserted into the upper cylinder body 101, the protrusion 103 is inserted into the longitudinal groove of the L-shaped groove 104, and the upper cylinder body 101 or the lower cylinder body 102 is rotated, and the protrusion 103 is locked in the horizontal groove of the L-shaped groove 104 die. One end of the lower cylinder 102 is provided with a...

Embodiment 2

[0052] like Figure 10 As shown, the structure of embodiment 2 is the same as that of embodiment 1, the difference is that the metal cylinder 1 is integrally formed, and one end of the metal cylinder 1 is provided with a metal mounting seat 15, and the metal mounting seat 15 is connected with the metal The barrel 1 is a welded or integrally formed structure.

Embodiment 3

[0054] like Figure 11 , Figure 12 , Figure 13 and Figure 14 As shown, the structure of embodiment 3 is the same as that of embodiment 1, the difference is that: the end of the upper cylinder 101 of the metal cylinder 1 is obliquely provided with a metal check door frame 14, and the two check door panels 2 are symmetrically arranged On this metal check door frame 14. When in use, the upper cylinder 101 of the metal cylinder 1 is covered with a reducing sleeve 19 for connecting with the wall. In addition, both the first connecting portion 1101 and the third connecting plate 1103 of the connecting bracket 6 are fixedly connected to the metal mounting base 15 .

Abstract

The invention discloses a fireproof check valve with an umbrella-shaped fireproof temperature sensing device. The fireproof check valve comprises a metal cylinder, a check door plate and the umbrella-shaped fireproof temperature sensing device, wherein the umbrella-shaped fireproof temperature sensing device comprises a guide column, a positioning shaft, a spring and a sliding block; first connecting rods are symmetrically and rotationally connected to the sliding block; second connecting rods are symmetrically and rotationally connected to the two ends of the positioning shaft; one end of each first connecting rod is hinged to the middle of the corresponding second connecting rod; a first fuse link and a second fuse link which are bonded are arranged between the upper end of the guide column and the sliding block; the upper end of the first fuse link is connected with the upper end of the guide column; and the lower end of the second fuse link is connected with the sliding block. According to the fireproof check valve, the linkage design of the sliding block, the first connecting rods and the second connecting rods is utilized, when the second connecting rods are driven by the sliding block and the first connecting rods to rotate along the positioning shaft, the second connecting rods rotate upwards to be away from the check door plate in the initial state and rotate downwardsto be pressed and buckled on the check door plate, the valve is tightly closed, and the fireproof isolation function is achieved.
