Description
Technical field
The utility model is related to a kind of locking device more particularly to a kind of refrigeration machine aeration valve locking devices.
Background technology
Currently, in refrigeration machine field, aeration valve is further fixed on refrigeration machine by the aeration valve on refrigeration machine by valve deck
On, and it is typically provided protrusion on aeration valve valve deck.But refrigeration machine long-time booting operation during, inevitably
Vibrations cause the control-rod of aeration valve (unidirectional stop valve) that can voluntarily rotate at leisure, when the valve opening of aeration valve is more than certain
After range, since the rotation of control-rod causes aeration valve to lose unidirectional cutoff effect, fallen to make refrigeration machine that lubricating oil occur
The phenomenon that stream.
Utility model content
For overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of lockings of refrigeration machine aeration valve to fill
It sets, which can prevent the control-rod on aeration valve from rotating.
The purpose of this utility model adopts the following technical scheme that realization：
A kind of refrigeration machine aeration valve locking device, including fixing piece and the locking member on the fixing piece, it is described solid
Determine part and be provided with through-hole along its axial direction, the through-hole is used to coordinate with the control-rod on aeration valve, the opposite end of the fixing piece
End face in face is equipped with groove, the groove be used for the male cooperation on aeration valve valve deck, the fixing piece is radially
It is provided with connecting hole, the connecting hole is extended to the internal face of the through-hole by the outer surface of the fixing piece, and the connecting hole is used
Coordinate in the locking member, the locking member is for supporting the control-rod on aeration valve with the control-rod on air make-up limitation valve
Rotation.
Further, the connecting hole is threaded hole, and the locking member is fastening bolt.
Further, the through-hole is combined into clearance fit with matching for the control-rod on aeration valve.
Further, the groove is combined into clearance fit with matching for the protrusion on valve deck.
Further, the fixing piece is cylinder.
Compared with prior art, the beneficial effects of the utility model are：
A kind of refrigeration machine aeration valve locking device of the utility model, it is fluted by being arranged, in use, groove is aligned
Protrusion pressure locking device on valve deck, so that locking device to be fixed on aeration valve, then by locking member is screwed into connecting hole extremely
Control-rod is withstood, to prevent the rotation of control-rod.
Description of the drawings
Fig. 1 is a kind of structural schematic diagram of refrigeration machine aeration valve locking device of the utility model；
Fig. 2 is the sectional view along A-A in locking device shown in FIG. 1.
In figure：1, fixing piece 11, through-hole；12, groove；13, connecting hole；2, locking member.
Specific implementation mode
In the following, in conjunction with attached drawing and specific implementation mode, the utility model is described further, it should be noted that
Under the premise of not colliding, it can be formed in any combination between various embodiments described below or between each technical characteristic new
Embodiment.
As shown in Figure 1, for a kind of refrigeration machine aeration valve locking device of the utility model, as shown in Fig. 2, for shown in Fig. 1
Locking device in sectional view along A-A, which includes fixing piece 1 and the lock on fixing piece
Tight part 2, fixing piece 1 are provided with through-hole 11 along its axial direction, and through-hole 11 is used to coordinate with the control-rod on aeration valve, the phase of fixing piece 1
To the end face in both ends of the surface be equipped with groove 12, groove 12 be used for the male cooperation on aeration valve valve deck, by groove 12 with
Male cooperation on aeration valve valve deck, the positioning to complete locking device and aeration valve are assembled, the radially company of being provided with of fixing piece 1
Hole 13 is connect, connecting hole 13 is extended to the internal face of through-hole 11 by the outer surface of fixing piece 1, and connecting hole 13 with locking member 2 for matching
It closes, the locking member 2 is for supporting rotation of the control-rod on aeration valve with the control-rod on air make-up limitation valve.
A kind of refrigeration machine aeration valve locking device of the utility model, by setting fluted 12, in use, by groove 12
The protrusion pressure locking device being aligned on valve deck, so that locking device to be fixed on aeration valve, then by locking member 2 is screwed into connection
Hole 13 is to control-rod is withstood, to prevent the rotation of control-rod.
Further, in order to enable locking effect is more preferable, connecting hole 13 is threaded hole, and locking member 2 is fastening bolt.
For the ease of assembly and disassembly, through-hole 11 is combined into clearance fit with matching for the control-rod on aeration valve；On groove 12 and valve deck
Protrusion with being combined into clearance fit.Fixing piece 1 is cylinder, to save material.
The above embodiment is only preferred embodiments of the present invention, cannot be protected with this to limit the utility model
Range, the variation of any unsubstantiality that those skilled in the art is done on the basis of the utility model and replacing belongs to
In the utility model range claimed.
