Abstract
The utility model provides a bleed bolt which comprises a bolt bar and a bolt head connected with the bolt bar, wherein the bolt bar comprises a thread section with threads, and a connecting section connected with the bolt head; and the outer surface of the thread section is provided with a groove used for bleeding air. The bleed bolt can realize the aim of bleeding air without being completely screwed out, thus being convenient and fast in operation.
Description
Technical field
The utility model relates to a kind of to prevent that steam from stopping up the device as characteristics, particularly relates to a kind of bleeder screw.
Background technique
At present in fact the air bleeder screw plug in the cooling system is exactly a plain bolt, when changing cooling liquid and exit, just can this bolt all need to be screwed out, and exitting needs again again to screw in after complete, complex operation step, and also bolt is lost easily; Simultaneously, the sealing gasket of the air bleeder screw plug of this structure is the pad that the building rubber compound by the metal frame of inside and outer parcel forms, its manufacturing process relative complex, and also outer layer rubber very easily tears damage in the process of degree of tightness repeatedly, and then seal failure.In general, the bleed air operation of this air bleeder screw plug is convenient not, the sealing configuration rapid wear; Use the air bleeder screw plug of this structure, the leakage after the replacing cooling liquid is very risky.
The model utility content
The purpose of this utility model provides a kind of bleeder screw easy to use.
Bleeder screw of the present utility model, comprise bolt shank and the bolt head that is connected with described bolt shank, described bolt shank comprises the linkage section that threaded thread section is set and is connected with described bolt head, is provided with the groove for venting on the outer surface of described thread section.
Bleeder screw of the present utility model, wherein, the bearing of trend of described groove is identical with the bearing of trend of described bolt shank.
Bleeder screw of the present utility model, wherein, described groove extends to the end of described bolt shank.
Bleeder screw of the present utility model, wherein, described groove is a plurality of, described a plurality of grooves are along the outer surface that circumferentially is uniformly distributed in described thread section of described bolt shank.
Bleeder screw of the present utility model, wherein, the outer surface of described bolt head is provided with along the circumferential extension of described bolt head and around the flange of described bolt head.
Bleeder screw of the present utility model wherein, is equipped with gasket seal on the linkage section of described bolt shank.
Bleeder screw of the present utility model, wherein, described gasket seal is round table-like, and the large end of described gasket seal and the end face of described bolt head and described flange fit tightly, and the small end face of described gasket seal is to the thread section of described bolt shank.
Bleeder screw of the present utility model will all not screw out by bolt when venting, can realize the purpose of exitting, and is easy to operate, quick.

Embodiment
As shown in Figure 1 and Figure 2, bleeder screw of the present utility model comprises bolt shank 1 and the bolt head 2 that is connected with bolt shank 1.Wherein, bolt shank 1 comprises the linkage section 12 that threaded thread section 11 is set and is connected with bolt head 2.Be provided with the groove 15 for venting on the outer surface of thread section 11.
Bleeder screw of the present utility model, wherein, the bearing of trend of groove 15 is identical with the bearing of trend of bolt shank 1.
Bleeder screw of the present utility model, wherein, groove 15 is a plurality of, a plurality of grooves 15 are along the outer surface that circumferentially is uniformly distributed in thread section 11 of bolt shank 1.
In the present embodiment, the shape of groove 15 is rectangles.
Bleeder screw of the present utility model, wherein, groove 15 extends to the end of thread section 11 by the middle part of thread section 11, and namely groove 15 extends to the end of bolt shank 1.
Bleeder screw of the present utility model, wherein, the outer surface of bolt head 2 is provided with along the circumferential extension of bolt head 2 and around the flange 20 of bolt head.When flange 20 screws in screw at bolt, with the edge close contact of screw, to play sealing and spacing effect.
Bleeder screw of the present utility model wherein, is equipped with gasket seal 30 on the linkage section 12 of bolt shank 1.The material of gasket seal 30 is the larger plastics of rubber or elasticity.
Bleeder screw of the present utility model, wherein, gasket seal 30 is round table-like, and the large end 31 of gasket seal 30 fits tightly with end face and the flange 20 of bolt head 2, and the small end 32 of gasket seal 30 is towards thread section 11.
In other embodiments of the present utility model, gasket seal 30 can be O type circle, also can be irregular rubber gasket, finally can bear repeatedly repeatedly the test of degree of tightness.
In conjunction with Fig. 3, shown in Figure 4, when bleeder screw of the present utility model in use, its bolt shank 1 is screwed in exhaust port 40, be provided with the groove 41 that rounds between the inwall of the edge of exhaust port 40 and exhaust port 40.Groove 41 is used for matching with the gasket seal 30 of bleeder screw.The gasket seal 30 of bleeder screw embeds in the groove 41 just, to strengthen the sealing to exhaust port 40.
When needs carry out bleed air operation, bleeder screw of the present utility model is rotated up by exhaust port 40, but needn't screw out fully, the top edge of the groove 15 on the outer surface of thread section 11 exceeds the edge of exhaust port 40, and then the gas in the exhaust port 40 just can outwards release from groove 15.Complete when venting, can easily the thread section 11 of bolt shank 1 must be screwed in the exhaust port 40 again, again exhaust port 40 is sealed.
Bleeder screw of the present utility model also can adopt the deflation structure of the bleed passage of similar hollow bolt, and it is deflatable function that final realization will bolt all screw off.
Bleeder screw of the present utility model will all not screw out by bolt when venting, can realize the purpose of exitting, simple operation; Round table-like gasket seal 30 can increase sealing area, improves sealing reliability, and Reusability repeatedly, solves the rapid wear problem of original sealing gasket.
The above only is preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
