The utility model provides a high pressure cleaner high -pressure pump air relief valve, direct function of adding discharge valve on the part of water pump itself, compact structure, it is more direct to exhaust, and required exhaustion time is shorter.
Description
Technical field
The utility model relates to jetting machine high-pressure service pump field, particularly, relates to a kind of automatic control pressure vent of jetting machine high-pressure service pump.
Background technique
Jetting machine high-pressure service pump period of exhaust long fault of water pump rate when self-priming is very high, needs suitable structure to reduce the self-priming time of water pump, improves the working life of water pump.
Common way increases special outlet valve joint in the outside of water pump, in order to get rid of the air in pipeline.This way outlet valve being placed in water pump outside, the shortcoming of appearance is: self-priming time is longer, reduce the working life of water pump, and material consumption is more, from environmental protection not the angle of energy-saving and emission-reduction.
Model utility content
For the defect existed in above-mentioned prior art, the purpose of this utility model is to provide a kind of automatic control pressure vent of jetting machine high-pressure service pump, on the part of water pump itself, directly adds the function of outlet valve, compact structure, exhaust is more direct, and required period of exhaust is shorter.
For achieving the above object, the technological scheme that the utility model adopts is as follows:
A kind of jetting machine high-pressure service pump automatic control pressure vent, comprise outlet valve housing and be arranged on the exhaust valve component of enclosure interior, described exhaust valve casing body is positioned on the water outlet plug of jetting machine high-pressure service pump, is made into integration with water outlet plug.
Described outlet valve housing offers a through cylindrical, hollow cavity from the water chamber end of jetting machine high-pressure service pump to air outlet end, form the back-up ring of exhaust valve component, ball, O type circle and spring, be arranged on successively in cylindrical, hollow cavity.
Described back-up ring and O shape circle are all fixedly mounted in hollow cavity, described ball is between back-up ring and O shape circle, described spring props up ball one end through O shape circle, and described ball external diameter is less than the external diameter of the cylindrical, hollow cavity at its place, moves in cavity to enable ball.
Described spring outer diameter is greater than the external diameter of air outlet end cavity, with make described ball head on spring move in cavity time, the other end of spring is fixed.
The internal diameter of described O shape circle is less than the external diameter of described ball, when moving to O shape circle position to make ball in cavity, encloses gluing, sealing with O shape.
The described outlet valve housing arranged outside in air outlet end in place has outside thread, for connecting outlet pipe.
Described ball is steel ball.
Described back-up ring is Steel Cable Baffle Ring.
Compared with prior art, the utility model has following beneficial effect:
Directly add the function of outlet valve at the part of water pump itself, such compact structure, exhaust is more direct, and the time is shorter;
Be arranged on out by outlet valve on water one-way valve plug, form one with water pump, make pipeline very short, thus make exhaust resistance little, self-priming time is short, improves the working life of water pump;
Material consumption is few, from the angle of energy-saving and emission-reduction, and environmental protection;
Due to the integrated design with water pump, make the profile of complete machine more aobvious attractive in appearance.
Accompanying drawing explanation
By reading the detailed description done non-limiting example with reference to the following drawings, other features, objects and advantages of the present utility model will become more obvious:
Fig. 1 is the structural representation of water pump one embodiment provided by the utility model;
Fig. 2 is the generalized section of outlet valve one embodiment in Fig. 1.
Embodiment
Below in conjunction with specific embodiment, the utility model is described in detail.Following examples will contribute to those skilled in the art and understand the utility model further, but not limit the utility model in any form.It should be pointed out that to those skilled in the art, without departing from the concept of the premise utility, some distortion and improvement can also be made.These all belong to protection domain of the present utility model.
Shown in Fig. 1, Fig. 2, jetting machine high-pressure service pump automatic control pressure vent 1 provided by the utility model, the exhaust valve component that there is outlet valve housing 2 and be arranged in outlet valve housing 2.Outlet valve housing 2 is positioned on the water outlet plug 3 of jetting machine high-pressure service pump, and is made into integration with this water outlet plug 3.
Outlet valve housing 2 is positioned at the water chamber of one end connection jetting machine high-pressure service pump of water outlet plug 3, and the other end is air outlet end, for Exhaust Gas.
Outlet valve housing 2 has through cylindrical, hollow cavity 20 from water chamber end to air outlet end, forms the Steel Cable Baffle Ring 10 of exhaust valve component, steel ball 11, O shape circle 12 and spring 13 and is arranged on successively in cavity 20.
Steel Cable Baffle Ring 10 is fixed in the cavity of water chamber one end, props up steel ball 11 from side.Spring 13 props up the opposite side of steel ball 11 through one end of O shape circle 12.The external diameter of steel ball 11 is slightly less than the external diameter of the cavity at its place, moves between the position can enclosing 12 and fixing back-up ring 10 to make steel ball 11 fixing O shape.
Spring 13 external diameter is slightly larger than air outlet end external diameter, that is, cavity 20 is formed with a small stair in the position of air outlet end and mounting spring 13, when being compressed in the process of steel ball 11 movement to make spring 13, spring only produces contraction owing to being located by this small stair, not mobile position.
The internal diameter of O shape circle 12 is slightly less than the external diameter of steel ball 11, to make steel ball 11 when moving to O shape and enclosing 12 position, encloses fit tightly sealing with O shape.
Outlet valve housing 2 there is outside thread 21, in order to install gas exhaust piping near the arranged outside of air outlet end.
Utility model works principle is as follows:
When steel ball 11 was energized at the water pump initial stage, the effect due to spring 13 power rests on the position at A place.Air in water pump is vented by outside steel ball 11 lateral.When inner air pressure discharged by water pump, water starts to press to steel ball 11, and steel ball 11 can overcome the elastic force of spring 13 under the effect of press water, promotes the position that steel ball 11 moves to B, encloses 12 gluing, sealings with O shape, realizes automatic vent and the function that can not leak.
Above specific embodiment of the utility model is described.It is to be appreciated that the utility model is not limited to above-mentioned particular implementation, those skilled in the art can make various distortion or amendment within the scope of the claims, and this does not affect flesh and blood of the present utility model.
