Abstract
Provided is a liquid seal dual-purpose valve for breathing and fire retarding. An annular liquid storing groove for storing sealing liquid is arranged on a valve seat and is provided with the sealing liquid. A valve cover is placed on the valve seat, and one end of the valve cover extends into the sealing liquid. No matter how high or low the pressure is in an oil tank, gas needs to be exchanged through the liquid. Due to the fact that no mechanical valve is required to be moved and sealed liquid is selected according to weather conditions, a freezing phenomenon is avoided, oil gas volatilization can be effectively reduced, and a shrunken tank phenomenon is avoided. In addition, the liquid seal dual-purpose valve for the breathing and the fire retarding is simple in structure and is an ideal substitute of an existing oil tank breathing valve and a fire barrier.
Description
Technical field
The utility model relates to the device of a kind of exhalation of tank and back-fire relief.
Background technique
(patent No.: ZL02202367.4) two closed chambers of use add the form of cross over pipe to disclosed utility model patent " two-way fluid-tight inhalation valve ", have realized the breathing and the back-fire relief function of oil tank.It with traditional spring or gravity type (like the patent No. is: the patent of invention of ZL92106510.8 tank valves) compare, do not have to need to move the machinery valve of (unlatching), avoided the generation of the sticking couplet of valve, jam phenomenon, improved reliability.But this patent structure is complicated, and volume is big, and cost is high, installs and uses inconvenience, and simultaneously, this patent is not introduced sealing fluid, and as with common water, can freeze winter, and inhalation valve was lost efficacy, and the safe operation of threat oil tank.
The model utility content
The main purpose of the utility model design is: overcome the said apparatus deficiency, design a kind of simple in structure, volume is little, cost is low, can adapt to various physical environments automatically, safe and reliable exhalation of tank and fire retardant device.
For realizing the model utility purpose, the technological scheme that the utility model is taked is:
The back-fire relief dual purpose valve is breathed in a kind of fluid-tight, includes valve seat, valve gap, sealing fluid; Valve seat is provided with the ring-like liquid storage tank of depositing sealing fluid; Ring-like liquid storage tank is made up of interior cylinder ring, the cylindrical band of column and bottom land, and the downside of its interior cylinder, also is provided with the flange that connects with oil tank; In the ring-like liquid storage tank sealing fluid is housed; Valve gap by interior cylinder ring, the cylindrical band of column and connect two the ring seal face constitute; Cylinder ring one end extend in the sealing fluid in the valve gap, and the valve gap cylindrical band of column is arranged on the ring-like liquid storage tank of the valve seat outside, prevents that rainwater from invading in the ring-like liquid storage tank; Be equipped with the through hole that supplied gas flows in the ring-like liquid storage tank of valve seat in cylinder ring and the valve gap on the cylinder ring.
Effect and course of action are:
When (in the oil tank) pressure in the valve raises; Sealing fluid in the ring-like liquid storage tank just is pressed towards the outside of cylinder ring in the valve gap; Rising along with pressure; Sealing fluid liquid level in the valve gap in the cylinder ring progressively reduces, when its liquid level is lower than in the valve gap cylinder ring vent, and just cylinder ring, sealing fluid discharge in cylinder ring, the valve gap in the ring-like liquid storage tank of the gas in the oil tank.
When (in the oil tank) pressure in the valve reduces; Sealing fluid in the ring-like liquid storage tank just is attracted to the inboard of cylinder ring in the valve gap; Reduction along with pressure; The outer sealing fluid liquid level of cylinder ring progressively reduces in the valve gap, when its liquid level is lower than in the valve gap cylinder ring vent, the outer gas of oil tank just in the valve gap in cylinder ring, sealing fluid, the ring-like liquid storage tank cylinder ring be drawn in the oil tank.
Through adjusting the height of sealing fluid in the ring-like liquid storage tank, can conveniently adjust inhalation valve breathing gas operating pressure value.Suitably cylinder ring is cut apart liquid area ratio in the ring-like liquid storage tank in the adjustment valve gap, can adjust to exhale or inhale pressure difference action ratio.Fill the sealing fluid number of times for reducing the resistance of gas flow, reducing, the minimum sectional area that ring-like liquid storage tank is cut apart by cylinder ring in the valve gap should be greater than the area of the pipeline that connects with oil tank (cylinder ring in the ring-like liquid storage tank).
When liquid area ratio is 1 in cylinder ring in the valve gap is cut apart ring-like liquid storage tank, exhale or inhale pressure difference to equate.At this moment, go out from ring-like liquid storage tank outer cylinder circulation for preventing sealing fluid, the height of sealing fluid should not exceed 1/2 of the ring-like liquid storage tank cylindrical band of column; For preventing that sealing fluid cylinder ring in the ring-like liquid storage tank from flowing into oil tank, the height of cylinder ring should exceed about 1/3 of the cylindrical band of column in the ring-like liquid storage tank.
During through valve, all need pass one section seal fluid because of the gas of (oil tank inside and outside) inside and outside the valve, high-temperature combustion gas in this way, behind this section liquid, temperature can reduce rapidly, has played the effect of back-fire relief.
Description of drawings:
The structural representation that Fig. 1 implements for the utility model;
Embodiment:
As shown in Figure 1, it can be calcium chloride solution, ethylene glycol solution or the lower liquid of transformer oils freezing temperature that back-fire relief dual purpose valve sealing fluid 3 is breathed in described fluid-tight, also can not freeze in the winter time, has improved the safety reliability of inhalation valve.Wherein, the calcium chloride price is lower, and its solution is lower than ordinary water to the corrosion of metal (iron), when the metal surface is coated with rust proof paint, and to almost not corrosion of metal, therefore, this patent recommendation.The solidifying point of calcium chloride solution such as following table:
| Weight (calcium chloride/water) % | 5 | 10 | 15 | 20 | 25 | 30 |
| Solidifying point ℃ | -2.44 | -5.98 | -10.96 | -18.6 | -29.9 | -48 |
Described fluid-tight is breathed back-fire relief dual purpose valve valve gap 2 and can be made with glass or transparent plastic, conveniently checks liquid level.As making, should establish watch window, conveniently to check liquid level with metal or other non-transparent material.
Ring-like liquid storage tank in the described valve seat 1 has the bolt 4 that discharges water, and is convenient for changing liquid and ring-like liquid storage tank is cleaned.
Described valve seat (1) is provided with flange, and convenience connects with oil tank.
