Specific embodiment
The technical solution of the utility model embodiment is explained below with reference to the attached drawing of the utility model embodiment and
Illustrate, but following embodiments are only the preferred embodiment of the utility model, and not all.Based on the implementation example in the implementation mode,
Those skilled in the art's obtained other embodiments without making creative work, belong to the utility model
Protection scope.
Referring to Fig. 3 and Figure 13, retention mechanism 9, for connecting bindiny mechanism 3 and valve block 2, including shoulder bolt 91 and nut
92, it successively includes bolt head 911, step section 912 and spiro rod section 913, the diameter of bolt head 911 that shoulder bolt 91 is axial along it
To the radial dimension of the radial dimension > spiro rod section 913 of size > step section 912, nut 92 is fixedly connected with spiro rod section 913, and
And the nut 92 can offset with step section 912.
In the present embodiment, retention mechanism 9 further includes elastic washer, elastic washer be clamped in bindiny mechanism 3 and valve block 2 it
Between, elastic washer includes one of spiral elasticity washer, wave spring washer and curved spring washers or a variety of.
Referring to figs. 2 and 3, valve, including valve body 1, valve block 2 and bindiny mechanism 3 with exhaust outlet 111, valve body 1, valve block 2
It is made with bindiny mechanism 3 of metal or other heat-resisting materials, bindiny mechanism 3 is for connecting valve block 2 and valve body 1 and can drive valve
Piece 2 closes exhaust outlet 111.
From figure 3, it can be seen that the valve body 1 of the present embodiment has exhaust passage 11, exhaust outlet 111 is arranged in exhaust passage 11
On, when valve block 2 closes exhaust outlet 111, the two sides that exhaust passage 11 is located at exhaust outlet 111 will be unable to realize the flowing of flue gas,
It means that the indoor flue gas of user cannot pass through valve and enter in exhaust duct, exhaust duct when valve block 2 closes exhaust outlet 111
Interior flue gas also cannot pass through valve and enter in user room.Certainly, in the prior art, valve body may include the ring with exhaust outlet
Exhaust passage is not present on such valve body for shape baffle.
Bindiny mechanism 3 on valve in such a way that valve block 2 closes exhaust outlet 111 there are three types of: 1, as shown in figure 3, valve includes
Second elastic element 8, the second elastic element 8 are one of the second torsional spring, tension spring and pressure spring, and the second elastic element 8 is for driving
