the upper cover comprises a cover body and a valve cover, the cover body covers the upper end of the first shell, the valve cover is connected to the cover body, the valve cover comprises a valve cover body and a limiting plate, the upper end of the valve cover body is connected with the cover body, the lower end of the valve cover body is inserted into the mounting seat, the limiting plate is connected into the valve cover body, a second through hole is formed in the limiting plate, and the valve cover body is cylindrical;
a membrane;
and the elastic piece is used for ensuring the sealing connection between the periphery of the lower end part of the valve cover body and the splicing part of the mounting seat.
Preferably, the elastic part is a metal ring in interference fit with the inner side surface of the lower end part of the valve cover body.
Further, the metal ring is an unclosed metal ring with a fracture on the peripheral surface.
Preferably, the inner diameter of the lower end of the valve cover body is gradually increased from top to bottom.
Preferably, a mounting groove is formed in the lower end face of the limiting plate, the guide column penetrates through the mounting groove, and the guide column is separated from the limiting plate.
Preferably, the elastic member is disposed on an inner circumferential surface of the lower end portion of the bonnet body and makes the lower end portion of the bonnet body have a tendency to expand outward.
Preferably, the diaphragm is sleeved on the guide post and located below the limiting plate, and when the diaphragm is attached to the limiting plate, the second through hole is completely covered in a sealing manner.
The beneficial effects of the utility model reside in that: the elastic piece enables the lower end part of the valve cover body to have the tendency of outward expansion, so that a splicing surface formed by splicing the lower end part of the valve cover body and the mounting seat can ensure complete sealing, the metal ring is not easy to deform, and the valve cover can play a supporting role for a long time; the guide post is separated from the mounting groove and is not contacted with the mounting groove, so that the valve cover body can be ensured to be tightly inserted into the mounting seat.

FIG. 2 is a cross-sectional view K-K of FIG. 1;
fig. 3 is a partial view a of fig. 2.
Detailed Description
The invention will be described in detail below with reference to an exemplary embodiment shown in the drawings:
as shown in fig. 1 to 3, the gas-oil separator includes a housing 0, an upper cover 2, a diaphragm 3, and an elastic member 4.
The casing 1 includes that the main part is the first casing 01 of tubbiness and the second casing 02 of being connected with first casing 01 upper end, the second casing 02 has that the part sinks in first casing 01, this part forms mount pad 5, mount pad 5 has the uncovered of orientation top, and its bottom forms valve body 6, be equipped with first through-hole 7 on the valve body 6 and be formed with guide post 8, the bottom forms the tubbiness of invertedly, first through-hole 7 is formed on the bottom part around the tubbiness part, guide post 8 is formed at the upper end of tubbiness part and is located central point. The first housing 01, the second housing 02, and the mount 5 are integrally formed.
The upper cover 2 comprises a cover body 9 covering the upper end of the first shell 01 and a valve cover 10 connected to the cover body 9, the valve cover 10 comprises a valve cover body 11 with the upper end connected with the cover body 9 and the lower end inserted into the mounting seat 5 and a limiting plate 12 connected to the valve cover body 11, a second through hole 14 is formed in the limiting plate 12, the valve cover body 11 is cylindrical, and the inner diameter of the lower end of the valve cover body 11 is gradually increased from top to bottom. And a mounting groove 13 is formed on the lower end face of the limiting plate 12, the guide post 8 penetrates through the mounting groove 13, and the guide post 8 is separated from the limiting plate 12. The cap body 9 and the valve cap 10 are integrally formed.
The diaphragm 3 is sleeved on the guide post 8 and located below the limiting plate 12, and when the diaphragm is attached to the limiting plate 12, the second through hole 14 is completely covered in a sealing manner.
The elastic piece 4 is used for ensuring that the periphery of the lower end part of the valve cover body 11 is in sealing connection with the splicing part of the mounting seat 5. The elastic element 4 is a metal ring in interference fit with the inner side surface of the lower end part of the valve cover body 11. The metal ring is an unclosed metal ring with a fracture on the peripheral surface. The elastic member 4 is provided on the inner circumferential surface of the lower end portion of the bonnet body 11 and gives the lower end portion of the bonnet body 11 a tendency to expand outward.
When the separator normally works, spacing board 12 top space, second through-hole 14, spacing board 12 below space and the space intercommunication of mount pad 5 bottom below, form oil-gas separation's passageway, atmospheric pressure in spacing board 12 below space and the space of mount pad 5 bottom below is too high, diaphragm 3 goes upward to go with second through-hole 14 shutoff, and cut apart the space of spacing board 12 top and the space of below, elastic component 4 makes the lower tip of valve gap body 11 have the trend of outside expansion, therefore the lower tip of valve gap body 11 can ensure completely sealed with the concatenation face of the formation of pegging graft of mount pad 5, and metal loop non-deformable, can play the supporting role for a long time.
