Description
Technical field
A kind of well mouth protector is the utility model is related to, is specifically related to a kind of well mouth sampling valve protection device.
Background technology
The sample cock of well head is the part that oil extraction operation personnel often operate, thus protection dress will not be generally equipped with to it
Put, in frequent operation, in the case that weather conditions are severe and well site is temporarily unattended, sample cock exist it is fragile, easily
The problem of by pirate of the open, in actual production, an elastic tape typically is covered to valve leading screw, but a certain degree of protection can only be played
Effect.
Utility model content
The purpose of this utility model is to be directed to above-mentioned technological deficiency, there is provided a kind of well mouth sampling valve protection device, is solved
The technical barrier effectively protected to sample cock.
Technical scheme：A kind of well mouth sampling valve protection device, include two circles of the different-diameter being connected through a screw thread
Cylindricality cover body, keyway is set on path cover body, it is characterized in that：Along the plain line direction of the big footpath cover body, at least one elasticity is set
Bonding jumper, resilient metal strip end set spline, spline fitted in the keyway of path cover body, the big footpath cover body it is interior
Portion sets fixed disk, supporting plate is set on the top of fixed disk, the end of supporting plate sets arcuate guide block, through arcuate guide
The hole of block and the fixed disk sets curved roof, and compression spring is set in the bottom of the fixed disk and curved roof, described
The end face providing holes of big footpath cover body, operation handle is set through the hole.
Beneficial effect：The utility model is simple in construction, easily makes, can not only be played after installation and be effectively protected work
With, and certain anti-theft function can be played, and can use for a long time, service free is safeguarded.
Brief description of the drawings
Accompanying drawing 1 is the structural representation of the utility model.
Embodiment
Referring to the drawings 1, include two cylindrical cover bodies 1 and 12 of the different-diameter being connected through a screw thread, path cover body 12
It is welded on the valve body of sample cock, and keyway 11 is set on path cover body 12, is set along the plain line direction of the big footpath cover body 1
One resilient metal strip 9, spline 10 is set in the end of resilient metal strip 9, spline 10 coordinates the keyway 11 in path cover body 12
Interior, the inside of the big footpath cover body 1 sets fixed disk 6, sets supporting plate 7 on the top of fixed disk 6, the end of supporting plate 7 is set
Put arcuate guide block 8, through the hole 3 of arcuate guide block 8 and the fixed disk 6 set curved roof 2, the fixed disk 6 with
The bottom of curved roof 2 sets compression spring 4, the end face providing holes of the big footpath cover body 1, operation handle is set through the hole
5。
After utility model installation, there is good protective effect for the sample cock under external environment, this
Outside, when needing to operate sample cock, it is necessary to withstand curved roof 2 using supporting operation handle 5, never cause arc
Shape top plate 2 pushes up key 10 of blooming, and so can just screw off big footpath cover body 1, and operation handle 5 can pack up when not in use, therefore should
Utility model can also play anti-theft function to a certain extent.
