Specific implementation mode
The utility model is further described below in conjunction with the accompanying drawings.Following embodiment is only used for clearly illustrating this
The technical solution of utility model, and the scope of protection of the utility model cannot be limited with this.
As shown in Figure 1, the present apparatus includes valve body 10, valve seat 13, valve plate 8, valve rod 5 and valve deck.Fluid is provided in valve body
Channel.There are two the valve seats being mutually parallel, valve plate to be arranged between two valve seats for setting in fluid channel.In this structure, fluid
Channel direction is denoted as axial direction, and two valve seats can also move in the axial direction.By the way that waveform spring is arranged by two valve seats
12, valve seat applies a pretightning force under the action of waveform spring, to the sealing surface of valve plate, and valve seat is made mutually to be compressed with valve plate.
Wherein, the sealing surface of valve plate is exactly the side of valve plate.
The upper and lower ends of valve body are both provided with valve deck in the present apparatus, are denoted as bonnet, 9 and bottom flange 16, bottom flange 16 respectively
Middle steel loop 15 is additionally provided between valve body 10.
Wherein, the middle part of bonnet, 9 is provided with valve rod 5.Valve rod 5 is connected with valve plate 8, and the other end of valve rod 5 is provided with
