Abstract
The utility model discloses a kind of improved gas pressure regulator, governor pressure regulating mechanism, including valve rod, the front end of the valve rod is provided with one and closes sphere, and the contact surface for closing sphere and pressure-regulating valve mouth is set to sphere, and the closing sphere is in contact with pressure-regulating valve mouth.The improved gas pressure regulator, governor pressure regulating mechanism, by checking on, closed surface is set to sphere, can improve the closing performance of pressure regulator, safer practicality.
Description
Technical field
The utility model belongs to gas pressure regulator, governor technical field, and in particular to a kind of improved gas pressure regulator, governor pressure regulation
Structure.
Background technology
Gas pressure regulator, governor is commonly called as pressure-reducing valve, and it is the gas flow by changing adjusted valve automatically to be also gas pressure regulating valve,
The equipment for making outlet gas keep authorized pressure.It is generally divided into two kinds of direct acting type and indirect acting type.Pressure regulator is combustion gas
A kind of Special valve on pipeline, no matter gas flow and upstream pressure how to change, downstream pressure can be kept stable
Device.Pressure regulator should be able to：1st, upstream pressure is reduced into a stable downstream pressure；2nd, when pressure regulator breaks down
Downstream pressure should be able to be limited in safe range.The closing face of current gas pressure regulator, governor valve rod front end be plane either its
His curved surface, very high is required to the fit dimension between valve rod and valve port, the otherwise closing of pressure regulator does not reach requirement.
Utility model content
The purpose of this utility model is to provide a kind of improved gas pressure regulator, governor pressure regulating mechanism, to solve the above-mentioned back of the body
The problem of being proposed in scape technology.
To achieve the above object, the utility model provides following technical scheme：A kind of improved gas pressure regulator, governor pressure is adjusted
Nodule structure, including valve rod, the front end of the valve rod are provided with one and close sphere, and closing sphere connects with pressure regulator pressure-regulating valve mouth
Contacting surface is set to sphere, and the closing sphere is in contact with pressure-regulating valve mouth.
Further, the contact surface for closing sphere is connected with pressure-regulating valve mouth and high-pressure gas entrance.
Technique effect of the present utility model and advantage：The improved gas pressure regulator, governor pressure regulating mechanism, by by valve rod
In with valve port contact surface be changed to sphere-contact from the plane contact in tradition, the design of sphere makes the safer practicality of pressure regulation.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure：Sphere, 3 pressure-regulating valve mouths, 4 high-pressure gas entrances are closed in 1 valve rod, 2.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
The utility model provides a kind of improved gas pressure regulator, governor pressure regulating mechanism as shown in Figure 1, including valve rod
1, the front end of the valve rod 1 is provided with one and closes sphere 2, and the contact surface of the closing sphere 2 of the front end of valve rod 1 is set to sphere, leads to
Cross closed surface of checking on and be set to sphere, the closing performance of pressure regulator, the closing sphere 2 and the phase of pressure-regulating valve mouth 3 can be improved
Contact, the contact surface for closing sphere 2 are connected with pressure-regulating valve mouth 3 and high-pressure gas entrance 4.
Finally it should be noted that：Preferred embodiment of the present utility model is the foregoing is only, is not limited to this
Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art
For, it can still modify to the technical scheme described in foregoing embodiments, or to which part technical characteristic
Progress equivalent substitution, all within the spirit and principles of the utility model, any modification, equivalent substitution and improvements made etc.,
It should be included within the scope of protection of the utility model.
