Background technique
At present, in the gasoline retail business, the Pull breaking ualve safety protection device that is absolutely necessary.When nozzle still hangs on the automobile, and automobile directly starts, and the pulling force that start forms can be applied on the oilling machine by nozzle and sebific duct, thus broken ring oilling machine.Oilling machine is in a single day destroyed, and fuel leakage just inevitably occurs, and so just is very easy to cause the generation of fire.And Pull breaking ualve is installed between nozzle and the sebific duct, perhaps between long length hose and the short sebific duct.When being subject to certain pulling force, the up and down valve body of Pull breaking ualve can break away from voluntarily, and closes oil circuit.Thereby the protection oilling machine, the generation of Accident prevention.
Now, the kind of Pull breaking ualve is many, but the mechanism that breaks generally is exactly two kinds, and a kind of is the shear pin form, and a kind of is the form of spring banding.The Pull breaking ualve of shear pin form is disposable Pull breaking ualve, can't recover after breaking.And the form of spring banding is reusable, but still has two problems, the first, and pulling force decay is too fast, and next time pull-off force is than front once reduce too many after the recovery; The second, when breaking, cause easily the working of plastics that cooperates with spring to damage.
The model utility content
The purpose of this utility model is to overcome the defective of prior art, and a kind of Pull breaking ualve is provided, and at the up and down collar of installation after Overheating Treatment between the valve body of Pull breaking ualve, in time realizes the up and down disengaging of valve body.
For achieving the above object, the utility model proposes following technological scheme: comprise upper valve body and lower valve body, described upper valve body and lower valve body comprise respectively upper end part and the end portion of hollow, the upper end part of the end portion of described upper valve body and lower valve body has respectively corresponding inner peripheral surface and outer peripheral surface, the upper end part of described lower valve body is plugged in the end portion of described upper valve body, the first groove is set on the outer peripheral surface of described lower valve body, corresponding described the first groove arranges the second groove on the inner peripheral surface of described upper valve body, between described the first groove and the second groove collar is installed.Collar is through heat treated, and the collar elasticity after Overheating Treatment is better, can recover very soon after the expansion, and is reusable.
Preferably, the upper-end surface of described the first groove is tilted conical surface, expands along tilted conical surface when collar expands, so that lower valve body and upper valve body break away from, the tilted conical surface material is metal material, and the tilted conical surface intensity of metal material is better, when Pull breaking ualve is broken, be difficult for damaged.
The upper end part of described upper valve body and end portion are respectively upper end cylindrical body and the lower end cylindrical bodys of hollow, and upper end cylindrical body external diameter is less than lower end cylindrical body external diameter, and the upper end part of described lower valve body is plugged in the lower end cylindrical body of described upper valve body.
The upper end part of described lower valve body comprises centrum and the cylindrical body that internal diameter diminishes from lower to upper, and the end portion of described lower valve body is cylindric lower end, and described the first groove is arranged on the described cylindrical outer peripheral surface.
Be respectively arranged with elastic seal ring on described upper valve body inner peripheral surface and the lower valve body outer peripheral surface.
Described Pull breaking ualve also comprises the spool that is arranged in upper valve body and the lower valve body, and described spool comprises upper valve core and the lower valve core that mutually holds, and described valve core cavity forms gas channels, forms asphalt channel between described spool and upper valve body and the lower valve body.
The beneficial effect of Pull breaking ualve of the present utility model is: (1) has good elasticity at the collar of installing between the valve body up and down after Overheating Treatment, and the pulling force decay is little, can very fast recovery after the expansion, so Pull breaking ualve can be reused; (2) will be arranged to the tilted conical surface of metal material on the first groove, intensity is good, is difficult for being damaged by collar, has preferably practicability.

Embodiment
Below in conjunction with accompanying drawing of the present utility model, the utility model embodiment's technological scheme is carried out clear, complete description.
As shown in Figure 1, the Pull breaking ualve that the utility model discloses, this Pull breaking ualve is arranged between oilling machine sebific duct (not shown) and the nozzle sebific duct (not shown), the upper valve body 1 and the lower valve body 2 that comprise socket connection, and be arranged on spool 3 in upper valve body 1 and the lower valve body 2, spool 3 comprises upper valve core 31 and the lower valve core 32 that mutually holds, and spool 3 inner chambers form gas channels 5, forms asphalt channel 6 between spool 3 and upper valve body 1, the lower valve body 2.
In conjunction with illustrated in figures 1 and 2, upper valve body 1 comprises upper end part 11 and the end portion 12 of hollow, the upper end part 11 of upper valve body 1 and end portion 12 are respectively upper end cylindrical body and lower end cylindrical body, upper end cylindrical body external diameter is less than lower end cylindrical body external diameter, be provided with the second groove 121 on the inner peripheral surface of the end portion 12 of upper valve body 1, be equipped with in the second groove 121 through heat treated collar 4, collar 4 is through heat treated, has preferably elasticity, can recover very soon after the expansion, elastic extenuation is slower, can reuse.
In conjunction with Fig. 1 and shown in Figure 3, lower valve body 2 comprises the upper end part 21 and cylindric end portion 22 of hollow, lower valve body 2 upper end parts 21 are divided into centrum 211 and the cylindrical body 212 that internal diameter diminishes from lower to upper, the upper end part 21 of lower valve body 2 is plugged in the upper valve body 1 lower end cylindrical body, the first groove 7 is arranged on the lower valve body 2 cylindrical outer peripheral surfaces, when not having pulling force to be applied to Pull breaking ualve, collar 4 is respectively arranged with elastic seal ring 8 on upper valve body 1 inner peripheral surface and lower valve body 2 outer peripheral surfaces between the first groove 7 and the second groove 121.
As shown in Figure 4, the upper-end surface 71 of the first groove is tilted conical surface, fits with collar 4 outer surfaces, tilted conical surface adopts preferably metallic material of intensity, such as aluminium matter, after valve body breaks away from up and down, tilted conical surface intensity is better, is difficult for damagedly, has prolonged working life of Pull breaking ualve.
When nozzle worked, collar 4 locked between the first groove 7 and the second groove 121, is used for connecting the up and down valve body of Pull breaking ualve; When the pulling force on the nozzle acts on Pull breaking ualve, collar 4 is along the stressed expansion of tilted conical surface, lower valve body 2 breaks away from fully with upper valve body 1 under the thrust of collar 4, cut off simultaneously asphalt channel 6, can effectively prevent fuel oil and the interior fuel leakage of sebific duct in the oilling machine, be difficult for causing the serious potential safety hazards such as fire.
