Description
Technical field
The utility model is a kind of sealing structure of reciprocating pump.
Background technology
High pressure painting is widely used in the spraying operations such as the spraying of house ornamentation emulsion paint, waterproof, anti-corrosion, anticorrosion of steel structure spraying,
Compared to traditional artificial Typical spray, which greatly enhances operating efficiency, the labor intensity of worker is reduced.Flush coater, its
Core component is plunger pump, and the core component of plunger pump is plunger rod and sealing ring, and plunger rod and sealing ring are consumable accessory, institute
How to extend the service life of plunger rod and sealing ring, turn into a big problem of this area.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of sealing structure of reciprocating pump, and it can extend
The service life of sealing ring.
A kind of in order to solve the above technical problems, technical solution of the sealing structure of reciprocating pump of the utility model
For：
A kind of sealing structure of reciprocating pump, including pump seat, the pressure release valve assembly and pressure regulator valve that are arranged on pump seat
Assembly, the pump seat is interior to be provided with plunger rod component, and the plunger rod component includes plunger rod, large sealing packing ring is arranged with plunger rod
With small sealing ring, in the lower mounting groove of pump seat, small sealing ring is matched in the upper mounting groove of pump seat for the large sealing packing ring matching；
The large sealing packing ring is consistent with small sealing ring structure, including body, and the body is annular, is provided with the end face of body
Section is in the annular groove of " V " type, and the annular tension spring that section is in " V " type, annular tension spring are provided with annular groove
There is the active force expanded outwardly all the time to the two side of annular groove；The inwall of the body seals for step multistage tooth form
Groove, outer wall are provided with least one of groove, sealing ring are provided with groove.
What the utility model can reach has the technical effect that：
Compared with prior art, the sealing structure of reciprocating pump of the present utility model, annular tension spring are recessed to annular
The two side of groove has the active force that expands outwardly all the time, and in plunger pump work, plunger rod high-speed motion vertically is so right
Large and small sealing ring produces pressure, and pressure is bigger, and the annular tension spring on the body of large and small sealing ring is inside, outside pushing out ring shape
The cell wall of groove, so that the sealing ring of body outer wall can be sealed preferably with mounting groove, if body outer wall and sheet are external
The sealing ring of wall is worn, then the supplement of the magnitude of interference is realized by annular tension spring；
Compared with prior art, the sealing structure of reciprocating pump of the present utility model, the inwall of body are more for step
Level tooth form seal groove, can constantly compensate the magnitude of interference automatically according to pressure and abrasion condition.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and detailed description：
Fig. 1 is the structural representation of the sealing structure of the utility model reciprocating pump；
Fig. 2 is Fig. 1 A-A sectional views；
Fig. 3 is the structural representation of small sealing ring of the present utility model.
Embodiment
Fig. 1 to Fig. 3 is referred to, the utility model provides a kind of sealing structure of reciprocating pump, including pump seat 1, setting
Pressure release valve assembly 2 and pressure regulating valve assemblies 3 on pump seat 1, the pump seat 1 is interior to be provided with plunger rod component, the plunger rod group
Part includes plunger rod 4, and large sealing packing ring 5 and small sealing ring 6 are arranged with plunger rod 4, and the large sealing packing ring 5 is matched in pump seat 1
Lower mounting groove（Do not marked in figure）Interior, small sealing ring 6 matches the upper mounting groove in pump seat 1（Do not marked in figure）It is interior；The large sealing packing ring 5
It is consistent with the structure of small sealing ring 6, including body 7, the body 7 are annular, are in provided with section on the end face of body 7
The annular groove of " V " type（Do not marked in figure）, in annular groove（Do not marked in figure）The interior annular tension spring provided with section in " V " type
8, annular tension spring 8 is to annular groove（Do not marked in figure）Two side there is the active force that expands outwardly all the time；The body 7
Inwall be step multistage tooth form seal groove, outer wall is provided with least one of groove 9, sealing ring 10 is provided with groove 9.
Specifically, the outer wall of the body 7 of large sealing packing ring 5 is provided with twice groove 9, the outer wall of the body 7 of small sealing ring 6 is provided with
One of groove 9.
Use principle of the present utility model is made an explanation below：
The sealing structure of reciprocating pump of the present utility model, there are large sealing packing ring 5 and small sealing ring 6, two sealing rings
Component is all static sealing, and the sealing ring 10 of the outer wall of body 7 seals the inwall for being against mounting groove, and the step of the inwall of body 7 is more
Level tooth form seal groove 13, multiple sealing lips 11 are formd, multiple sealing lips 11 are fitted in the outer wall of plunger rod 4, so as to reach
To sealing effectiveness, when sealing ring 10, the outer wall of body 7 or sealing lips 11 cause abrasion due to long-time application, annular tension
Spring 8 is to the annular groove on body 7（Do not marked in figure）Two side has outside active force, then makes annular on body 7 recessed
Groove（Do not marked in figure）The part on both sides is with annular groove（Do not marked in figure）Centered on expand outwardly so that the inwall of body 7 is tight
Compression leg stopper rod 4, the sealing ring 10 on outer wall are close to mounting groove, realize the supplement of the magnitude of interference, and keep the shape of body.Work
When, operating pressure is bigger, and medium is bigger to the extruding force of large and small sealing ring in the pump housing 12, and sealing effectiveness is better；With sealing
The abrasion of circle, annular tension spring 8 can supplement the magnitude of interference and keep the shape of sealing ring；It is relative with plunger rod 4 on body 7 to transport
Step multistage tooth form seal groove is designed at dynamic sealing, the magnitude of interference is constantly compensated according to pressure and abrasion condition automatically, so
Both the load of pump had been reduced, has improved the service life of sealing ring again, had been shown according to experiment, sealing structure of the present utility model,
More lip sealing ring life-spans than routine are doubled.
A kind of sealing structure of the reciprocating pump provided above the utility model embodiment is described in detail,
Specific case used herein is set forth to principle of the present utility model and embodiment, and the explanation of above example is only
It is to be used to help understand the technical scheme disclosed in the utility model；Meanwhile for those of ordinary skill in the art, according to this
