Description
Technical Field
The utility model belongs to the technical field of the pitch storage tank, concretely relates to breather valve for pitch storage tank.
Background
The internal temperature and pressure of the asphalt storage tank can rise in the operation process, and at the moment, if a small amount of gas at the top of the asphalt storage tank is not discharged in time, the safety accident of the asphalt storage tank can be caused.
At present, the pitch storage tank is when storage tank top is gaseous in needs emission, and the vent can directly be opened to the most in discharging oil gas to the atmosphere, and this not only can cause the pollution at pitch storage tank top, also can be because the volatilization of oil gas moreover, and can not guarantee the safe operation of pitch storage tank, has also caused serious pollution to atmospheric environment simultaneously.
Therefore, it is urgently needed to design a breather valve to be installed at the top of the asphalt storage tank for maintaining the air pressure balance in the asphalt storage tank, ensuring the safe operation of the breather valve and avoiding atmospheric pollution.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: overcome prior art's not enough, provide a breather valve for pitch storage tank, can maintain the atmospheric pressure balance in the pitch storage tank, simultaneously can effectually avoid atmospheric pollution, energy-concerving and environment-protective with oil vapor recovery.
The utility model discloses an adopt following technical scheme to realize:
the breather valve for the asphalt storage tank comprises a valve cover, a barrel and a flange, wherein the valve cover is of a trapezoidal structure with a top sealed and a bottom opened, the valve cover is fixed on the upper part of the barrel through a support piece, an oil vapor recovery disc is connected onto the barrel, the top of the oil vapor recovery disc is inclined towards the bottom, a leak hole is formed in the joint of the barrel and the oil vapor recovery disc, and the flange is connected to the bottom of the barrel.
The upper part of the cylinder body is arranged in the valve cover.
Preferably, the inner surface of the oil vapor recovery disc is provided with arc-shaped grooves distributed in a circular array for guiding the recovered oil vapor to flow into the leakage holes.
Install the breather valve in the top of pitch storage tank through the flange, oil gas rises to the valve bonnet portion through flange joint department, and steam discharges, and heavier oil gas class falls into oil vapor recovery dish by the valve gap, retrieves to jar in through the small opening, reaches saving environmental protection effect.
Compared with the prior art, the beneficial effects of the utility model are as follows:
the utility model discloses simple structure, convenient operation can maintain the atmospheric pressure balance in the pitch storage tank, can effectually avoid atmospheric pollution, energy-concerving and environment-protective with vapor recovery system simultaneously.

FIG. 2 is a top view of the oil vapor recovery pan of the present invention;
fig. 3 is a perspective view of the present invention;
in the figure: 1. a valve cover; 2. a support member; 3. a barrel; 4. an oil vapor recovery pan; 5. a leak hole; 6. a flange; 7. an arc-shaped groove.
Detailed Description
The present invention will be further described with reference to the accompanying drawings.
As shown in fig. 1-3, the breather valve for the asphalt storage tank, including valve gap 1, barrel 3 and flange 6, valve gap 1 be the sealed bottom open-ended trapezium structure in top, valve gap 1 passes through support piece 2 to be fixed the upper portion of barrel 3, the upper portion of barrel 3 locate inside valve gap 1 be connected with oil vapor recovery dish 4 on the barrel 3, oil vapor recovery dish 4 top sets up to the bottom slope, barrel 3 is equipped with small opening 5 with oil vapor recovery dish 4 junction, flange 6 connects in the bottom of barrel 3. The inner surface of the oil vapor recovery disc 4 is provided with arc-shaped grooves 7 distributed in a circular array.
Install the breather valve in the top of pitch storage tank through flange 6, oil gas rises to valve gap 1 portion through barrel 3 through flange 6 junction, and steam discharges, and heavier oil gas class falls into oil vapor recovery dish 4 by valve gap 1, flows into barrel 3 through the small opening and retrieves to jar in, reaches saving environmental protection effect.
Of course, the above description is only a preferred embodiment of the present invention, and should not be taken as limiting the scope of the embodiments of the present invention. The present invention is not limited to the above examples, and the technical field of the present invention is equivalent to the changes and improvements made in the actual range of the present invention, which should be attributed to the patent coverage of the present invention.
