Abstract
The utility model relates to a two-ball closed exhaust valve of a mixed reaction tank. The two-ball closed exhaust valve of the mixed reaction tank is arranged on the top of the mixed reaction tank of an oilfield wastewater station, and automatic water sealing and air exhaust are achieved. The exhaust valve comprises an inflow base and liquid collection chambers. Each liquid collection chamber is provided with a float ball, a sealing member, and a sealing cover. An upper liquid collection chamber is connected between the sealing member and the sealing cover. The upper liquid collection chamber is provided with a ball seat, an upper liquid collection chamber shell body, an upper float ball and an upper sealing member. Centre holes are formed in the ball seat and the upper sealing member to be used as exhaust ducts of the upper liquid collection chamber. Due to the fact that the upper float ball is placed in the upper liquid collection chamber which is arranged between the ball seat and the upper sealing member, functions of two-ball closed water sealing and air exhaust are achieved. Two liquid collection chambers are design and the water is sealed by the two float balls according to the floater principle and the engine oil closed principle of a device, the inflow water is sealed when liquid level of the reaction tank is high, and air is exhausted when the liquid level of the reaction tank is low. Manual operation is omitted by the two-ball closed exhaust valve of the mixed reaction tank, personal safety of staff is ensured, and working efficiency is improved.
Description
Technical field
The utility model belongs to the two ball closed exhaust valves of oil field mixing reaction tank special-purpose water shutoff venting gas appliance, particularly mixing reaction tank, is installed on the mixing reaction tank deck at oilfield sewage station, realizes the automatic water seal exhaust.
Background technique
For a long time, crude stabilizer, the mixing reaction tank of sewage plant, the gas discharging of deaerator, all existing needs improvements, needs artificial exhaust such as sewage mixing reaction tank, and upper tank exhaust is exactly a potential safety hazard, high tank more than eight meters, ladder straight up and down, and the workman on these posies substantially is the woman worker.Because be subject to the impact of air-resistance phenomenon, the water that comes of petrol station does not arrive sewage mixing reaction tank, pump is not shown and is anhydrated, although tank deck also is provided with outlet valve, but because structural imperfection is not tight to hydraulic seal, do not realize automatic vent, also cause simultaneously mixing reaction tank ambient contamination.Woman workers went up the tank exhaust in one day several times for this reason, climb up and climb down, and were prone to accidents, and had serious potential safety hazard.Being that production safety and work are convenient considers, needs to make a kind of drain tap of can enclosed liquid, automatically opening.
Summary of the invention
This practical purpose provides the two ball closed exhaust valves of mixing reaction tank, be connected with the outlet pipe of mixing reaction tank top, it is not tight to solve water shutoff, rely on the problem that manually exhaust is greatly dangerous and cause mixing reaction tank ambient contamination, for the post personnel provide a kind of safe and convenient, need not climb up back and forth the automatic control pressure vent that climbs down venting, for the tank deck exhaust provides safety guarantee.
The utility model is achieved in that the two ball closed exhaust valves of mixing reaction tank comprise coming water-bed seat and hydrops chamber, and the hydrops chamber is provided with ball float, Sealing and sealing cover.Be connected the hydrops chamber between Sealing and sealing cover, upper hydrops chamber is provided with ball seat, upper hydrops chamber housing, upper floating ball and upper Sealing, and ball seat and upper Sealing are equipped with center hole, as the exhaust passage of upper hydrops chamber.Upper floating ball places the upper hydrops chamber housing between ball seat and the upper Sealing, realizes the function of two airtight water shutoffs of ball, exhaust.
This practical beneficial effect is, the utility model design two hydrops chambers according to the machine oil sealing principle of float principle and equipment, and two ball float water shutoffs can the water seal that comes when liquid level is high in the retort be lived exhaust when the interior liquid level of tank is low.When coming water, the indoor ball float generation of the hydrops buoyancy that is positioned at the bottom is up, the liquid in the sealing hydrops chamber.There is the water of small part not seal if be positioned at the hydrops chamber of bottom, so just enters in the hydrops chamber, continue to produce secondary seal by upper floating ball and upper Sealing, water seal is lived.When gas is arranged, the density of ball float itself, heavier than the density of gas, ball float is motionless, and gas, is discharged from top, upper hydrops chamber discharged to upper hydrops chamber more to the outside from the hydrops chamber of below.During the indoor fluid low of below hydrops, the gas in the liquid, again the center hole by ball seat with gas discharged in the upper hydrops chamber.When gas drained, the liquid level of mixing tank was slowly set up again, produced to change over to normally, and equipment continues to run well.The utility model also is fit to the breathing separatory exhaust of the large tank of crude oil in actual applications, because the pressure of this outlet valve is the working pressure that the natural height according to storage tank is complementary, the height of storage tank more high sealing effect is better.The utility model has saved manual operation, greatly reduces unsafe factor and labor intensity that manual operation brings, has ensured employee's personal safety, has improved working efficiency.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed description.Referring to accompanying drawing, the two ball closed exhaust valves of mixing reaction tank comprise coming water-bed seat 2 and hydrops chamber 3, and hydrops chamber 3 is provided with ball float 1, Sealing 4 and sealing cover 6, and ball float 1 places the hydrops chamber housing between water-bed seat 2 and the Sealing 4.Be provided with relief opening 7 at sealing cover 6, come water-bed seat 2 and Sealing 4 to be equipped with center hole, as the exhaust passage.Be connected hydrops chamber 10 between Sealing 4 and sealing cover 6, upper hydrops chamber 10 is provided with ball seat 5, upper hydrops chamber housing, upper floating ball 9 and upper Sealing 8, and ball seat 5 and upper Sealing 8 are equipped with center hole, as the exhaust passage of upper hydrops chamber 10.Upper floating ball 9 places the upper hydrops chamber housing between ball seat 5 and the upper Sealing 8, realizes the function of two airtight water shutoffs of ball, exhaust.Ball seat 5 two ends are threaded with hydrops chamber housing and upper hydrops chamber housing respectively; Upper Sealing 8 is fixed between hydrops chamber housing and the sealing cover 6, and upper hydrops chamber housing is threaded with sealing cover 6.In the future water-bed seat 2 is connected and can uses with the outlet pipe of tank deck.Produce under normal circumstances, hydrops chamber 3 interior liquid are full, and ball float 1 fully contacts hydraulic seal is lived with Sealing 4.
