Description

Overflow-preventing exhaust valve

Technical Field

The utility model relates to a pressure release technical field, in particular to end discharge valve that overflows.

Background

When liquid is conveyed in an oil tank, a storage tank and the like, an exhaust valve needs to be arranged at the highest point of the oil tank, the storage tank and the like to perform exhaust and pressure relief work, so that the safety performance of a carrier is improved. The existing exhaust valve has complex structure and high manufacturing cost; the overflow-preventing effect is not obvious in the exhaust process; and has no function of corrosion prevention. To this end, we propose an anti-spill vent valve.

SUMMERY OF THE UTILITY MODEL

A primary object of the present invention is to provide an overflow-preventing exhaust valve, which can effectively solve the problems of the prior art.

the overflow-preventing exhaust valve comprises a rotating end block, a threaded column and a closing edge, wherein the threaded column is arranged at the top of the rotating end block, the closing edge is embedded in the top of the threaded column through a mounting groove, a communicating hole is formed in the closing edge, a hollow cavity structure is arranged in the threaded column, a spring is arranged at the bottom of the closing edge, a steel ball is arranged at the bottom end of the spring, and a taper pressure relief opening is formed in the bottom in the threaded column.

Further, the bottom end of the steel ball is located in the conical pressure relief opening.

Further, the rotating end block and threaded post are made of corrosion resistant aluminum material.

Further, the outer side of the rotating end block is provided with anti-slip stripes.

Furthermore, one end of the top of the rotating end block is provided with an exhaust hole, and the exhaust hole is communicated with the taper pressure relief port through an exhaust channel.

Compared with the prior art, the utility model discloses following beneficial effect has:

1. the overflow-stopping exhaust valve is screwed into a pressure relief opening with a corresponding threaded pressure relief pipe to play a role in sealing and overflow stopping, when pressure is formed in a carrier such as an oil tank body, a steel ball in the overflow-stopping exhaust valve moves downwards under the action of a spring during pressure relief to leak out a taper pressure relief opening to finish the work of exhausting and pressure relief, and when the pressure in the carrier such as an oil tank pipeline is relieved, the spring automatically jacks up the steel ball to close the pressure relief opening to automatically finish the action of pressure relief, so that the deformation of the carrier due to overlarge pressure is prevented.

2. The rotary end block and the threaded column are made of anti-corrosion aluminum materials, are resistant to corrosion of various organic solvents and acid and alkali, high in strength, not easy to peel off, durable and capable of well protecting the rotary end block and the threaded column.

3. The outside of rotating end block is provided with anti-skidding stripe, effectively plays the effect that the antiskid is taken off at the rotating in-process, and this novel discharge valve that only overflows, the effect is showing, and the cost is low, and the production of being convenient for has satisfied the multiple demand in the use, is fit for extensively using widely.
