Abstract
The utility model discloses an exhausting bolt for a boiler. The exhausting bolt comprises a screw rod, the end portion of a first end of the screw rod is fixedly connected with a sealing end cap, a second end of the screw rod is a free end with the periphery being provided with threads, an exhausting port is arranged at the end portion of the second end of the screw rod, an exhausting channel is arranged in the center of the screw rod in the axial direction of the screw rod, the exhausting port is communicated with the exhausting channel, the first end of the screw rod is provided with a first exhausting hole, and the first exhausting hole is communicated with the exhausting channel. The exhausting bolt for the boiler has the advantages of being simple in structure, adjustable in air displacement, and capable of achieving quick pressure relief.
Description
Technical field
The utility model relates to a kind of bolt, especially relates to a kind of bleeder screw for boiler.
Background technique
Boiler can produce a large amount of steams in the course of the work, may cause the bursting of boilers or terminal equipment to damage when pressure is excessive, have very big potential safety hazard, the bleeder screw of available technology adopting is solid construction, if need pressure release all to back-out, and can't realize regulating air displacement.
Summary of the invention
The technical problems to be solved in the utility model provide a kind of simple in structure, air displacement is adjustable, can realize the bleeder screw that is used for boiler of quick pressure releasing.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of bleeder screw for boiler, described bleeder screw comprises screw rod, the end of described screw rod first end is fixedly connected with end cover, second end of described screw rod is free end, and its periphery is provided with screw thread, and the end of described screw rod second end is provided with relief opening, described screw rod center is provided with air outlet flue along the screw axial direction, described relief opening is communicated with described air outlet flue, and first end of described screw rod is provided with first exhaust port, and described first exhaust port is communicated with described air outlet flue.
As further improvement in the technical proposal:
First end of described screw rod is provided with second exhaust port, and described second exhaust port is communicated with described air outlet flue.
Place, the center axis of described first exhaust port and place, the center axis of described second exhaust port are vertical mutually.
The utlity model has following advantage: bleeder screw of the present utility model is installed on the boiler by screw thread, this moment, first exhaust port and second exhaust port were by shutoff, can't exhaust, when pressure is excessive when needing pressure release, with the screw rod certain-length of back-outing, first exhaust port is opened, be communicated with ambient air, the interior pressure of boiler this moment can be leaked by first exhaust port, the certain distance of also can further screw rod being back-outed is opened second exhaust port, by first exhaust port and the pressure release simultaneously of second exhaust port, strengthen air displacement, accelerate pressure release speed.
