Abstract
The utility model discloses a deflating bolt. The deflating bolt comprises a hollow bolt, wherein a screw hole is axially formed at the upper part of the hollow bolt and a first gas through hole communicated with the screw hole is formed at the lower part of the hollow bolt; a screw is arranged inside the screw hole; and the screw is in threaded connection with the screw hole. The deflating bolt is simple and practical, and convenient to process, and can be produced in batches; during regulation for deflating, the working space is small, so that requirements of a user are met; the deflating efficiency of an oil supplying system is fundamentally improved; oil waste in the deflating process is reduced; and environment pollution and safety hazards in the assembly process are avoided.
Description
Technical field
The utility model relates to and a kind ofly is applicable to that the fuel feeding of single-cylinder farm transport vehicle is the bolt of device, relates to specifically a kind ofly can realizing the Oil Guide of engine oil path when ventilation, the bleeder screw of blowout prevention function.
Background technique
The bleeder screw structure all is the hollow bolt that motor carries before dispatching from the factory on the Chinese market at present, with the three-wheeled motor car is example, need during venting hollow bolt is unscrewed, then from fuel tank fuel filler neck bubbling air, whole oil circuit under action of air pressure, make diesel oil from the fuel tank to the hollow bolt between exhaust, inevitably to there be part diesel oil to flow out from hollow bolt, because of its structure special, the diesel oil that flows out can't flow in the fixed container, causes the phenomenon of polluting the working site, causing diesel oil waste.
Present technique is utilized bleed screw to cooperate hollow bolt to form and is sealed and easy single-cylinder engine oil supply system deflation structure, is applicable to present Chinese single-cylinder farm transport vehicle.
The model utility content
Problem to be solved in the utility model provides a kind of engine oil path of can realizing at the Oil Guide in when ventilation, the bleeder screw of blowout prevention function, can solve present single-cylinder farm transport vehicle engine oil pipeline and when ventilating, spray outside the diesel oil, thereby cause the phenomenon polluting the working site, cause diesel oil waste.
In order to address the above problem, the utility model by the following technical solutions:
A kind of bleeder screw comprises hollow bolt, and the top of described hollow bolt is provided with screw vertically, and the bottom is provided with first vent that is communicated with screw, is provided with screw in screw, and described screw is threaded with screw.
Below be the utility model for further improvement of these options:
The diameter of described screw is greater than the diameter of first vent.
Further improve: the lower end of described screw has conical surface, and described conical surface can seal first vent.
Further improve: the bottom of hollow bolt radially is provided with second vent that is communicated with first vent.
Further improve: be provided with blind hole in the described screw vertically, the bottom of described screw radially is provided with the 3rd vent that is communicated with respectively with blind hole and screw.
Further improve: be provided with rubber seal between the lower end of described screw and the screw.
Further improve: described rubber seal is arranged on the screw near on the excircle above the 3rd vent.
In the time of need not exitting at ordinary times, screw is screwed, and the conical surface of screw lower end is blocked first vent fully, makes that the blind hole and first vent are not connected, be both because rubber seal and the seal action that screw is connected with screw thread make it reach the effect of sealing fully.
When exitting work, feeding gas at fuel tank fuel filler neck place makes the oil pipe road produce pressure, upper end at screw puts oil guide pipe, unclamp screw with spanner, the conical surface of screw lower end breaks away from first vent, make the blind hole and first vent communicate by the 3rd vent, gas in the pipeline is flowed out along first vent and the 3rd vent, reached the effect of venting, the diesel oil of discharging is collected use again, reach the purpose of venting path, play seal action, prevent exosmosing of oil effectively because rubber seal is connected combination with screw with screw thread.
This device is simple and practical, and is easy to process, is convenient to produce in batches, working space is little when regulating venting, meets consumers' demand, and improves the efficient of oil supply system venting from the source, reduce the waste of oil in the deflation course, avoid the pollution of environment and the potential safety hazard of assembly process.
The utility model is described in further detail below in conjunction with drawings and Examples:
Description of drawings
Accompanying drawing 1 is the utility model embodiment's a structural representation;
Accompanying drawing 2 is the structural representation of the utility model embodiment hollow core bolt;
Accompanying drawing 3 is the structural representation of bleed screw among the utility model embodiment.
Among the figure: the 1-hollow bolt; The 2-screw; 3-second vent; The 4-screw; The 5-blind hole; The 6-rubber seal; 7-the 3rd vent; 8-first vent; The 9-conical surface.
Embodiment
Embodiment, as shown in Figure 1 and Figure 2, a kind of bleeder screw, comprise hollow bolt 1, the top of described hollow bolt 1 is provided with screw 2 vertically, and the bottom is provided with first vent 8 that is communicated with screw 2, be provided with screw 4 in screw 2, described screw 4 is threaded with screw 2.
The diameter of described screw 2 is greater than the diameter of first vent 8.
The bottom of hollow bolt 1 radially is provided with second vent 3 that is communicated with first vent 8.
As shown in Figure 3, the lower end of described screw 4 has conical surface 9, and described conical surface 9 can be with 8 sealings of first vent.
Be provided with blind hole 5 vertically in the described screw 4, the bottom of described screw 4 radially is provided with the 3rd vent 7 that is communicated with respectively with blind hole 5 and screw 2.
As shown in Figure 1, during installation, on the excircle above screw 4 close the 3rd vents 7, be set with rubber seal 6.
In the time of need not exitting at ordinary times, screw 4 is screwed, and the conical surface 9 of screw 4 lower ends is blocked first vent 8 fully, makes that the blind hole 5 and first vent 8 are not connected, be both because the seal action that rubber seal 6 and screw 2 and screw 4 are threaded makes it reach the effect of sealing fully.
When exitting work, feeding gas at fuel tank fuel filler neck place makes the oil pipe road produce pressure, upper end at screw 4 puts oil guide pipe, unclamp screw 4 with spanner, the conical surface 9 of screw 4 lower ends breaks away from first vent 8, make the blind hole 5 and first vent 8 communicate by the 3rd vent 7, gas in the pipeline is flowed out along first vent 8 and the 3rd vent 7, reached the effect of venting, the diesel oil of discharging is collected use again, reach the purpose of venting path, seal action is played in combination because rubber seal 6 and screw 2 and screw 4 are threaded, and prevents exosmosing of oil effectively.
This device is simple and practical, and is easy to process, is convenient to produce in batches, working space is little when regulating venting, meets consumers' demand, and improves the efficient of oil supply system venting from the source, reduce the waste of oil in the deflation course, avoid the pollution of environment and the potential safety hazard of assembly process.
