Of course, the shape of the mounting plate 1 can also be designed differently as needed. In other embodiments, the mounting hole unit can also be composed of a plurality of mounting holes arranged in a linear array, with the arrangement direction of the plurality of mounting holes parallel to the axial direction of the check valve stem 100. The mounting hole is a circular hole 1. Furthermore, in other embodiments, the mounting hole unit here can also be formed on the protective cover body 1. Specifically, the protective cover body 1 is provided with a plurality of mounting holes, and the protective cover body 1 is directly connected to the mounting plate 2 32 through the mounting holes on the protective cover body 1.

[0031] The number of the mounting hole units may be one or more, and the number of the adjustment hole units may be one or more. In this embodiment, the number of the adjustment hole units is the same as that of the mounting hole units, and both are set to 2.

[0032] In this embodiment, the number of connecting members 1 is plural, and the connecting members 1 are bolts 33. The bolts 33 are sequentially passed through the adjustment hole unit and the mounting hole unit and then tightened with nuts. By adjusting the position of the bolts 33 within the adjustment hole unit, the protective cover body 1 is moved toward or away from the check valve 100. The number of connecting members 1 is preferably multiple. In this embodiment, the number of connecting members 1 is four. By adjusting the position of the bolts 33 within the adjustment hole unit, the horizontal distance between the mounting plate 1 31 and the mounting plate 2 32 is adjusted, thereby moving the protective cover body 1 toward or away from the check valve 100. In other embodiments, the mounting hole and the adjustment hole may be threaded holes, in which case the number of connecting members 1 may also be one.

In this embodiment 2, the adjustment hole unit is a second waist hole 321, the length of which is perpendicular to the axial direction of the check valve stem. Of course, in other embodiments, the adjustment hole unit can be composed of a plurality of adjustment holes arranged in a linear array, with the arrangement direction of the plurality of adjustment holes being perpendicular to the axial direction of the check valve stem.

[0040] Specifically, in this embodiment 2, the number of adjustment hole units is set to 2 groups and is spaced apart up and down. The 2 groups of adjustment hole units are all waist holes 321. The waist holes 321 in each group are symmetrically arranged on the mounting plate 2. Each support plate has two mounting holes corresponding to the two groups of waist holes 321. The mounting holes here are waist hole-shaped. The number of screws 34 is set to four, and each two are a group and are fixed by adjusting nuts 35 after passing through the waist holes 321 of each group and the corresponding mounting holes at the same time. The distance between the mounting plate 1 31 and the mounting plate 2 32 is adjusted by adjusting the position of the adjusting nut 35 on the screw 34 to drive the protective cover body 1 closer to or away from the check valve 100.
