Description

Energy-saving pneumatic liquid discharging valve

Technical field

The utility model relates to a kind of liquid discharging valve, especially a kind of energy-saving pneumatic liquid discharging valve.

Background technique

It is very extensive that pressurized air is used in industry; And pressurized air accumulates more moisture content easily in generation, running, makes troubles for the gas user, as: when with the entrained air water in gas instrument or the equipment; Water can wash out the lubricant oil in these equipment; Thereby cause motor and bearing excessive loss, finally increase maintenance expenses, going slick property of some instruments (especially pneumatic hammer, driling machine, hoist and percussion hammer) and efficient can greatly reduce;

In addition, spray paint, glazing, food stirring and other with gas technology in, water does not allow to exist;

In instrument usefulness gas system, water does not allow to exist yet, and reason is that the water capacity is prone to be attached on the valve nozzle, and gathers dirt, causes the fluctuation of service or the fault of sensor;

And for example in the field of pressurized air as transmitting power; When water when the pipeline lower is assembled, can reduce pipeline transmission capacity, and when water enters into equipment with very high speed; Can cause many potential hazards; As equipment being produced bigger impact, when perhaps weather was colder, the water that gathers can freeze and with frost crack pipe.

Therefore pneumatic liquid discharging valve need be set on compressed air line drains airborne water; The problem that existing pneumatic liquid discharging valve exists is: in drainage procedure, the pressurized air of a part can be drained along with water together, thereby causes the increase of gas consumption, causes the wasting of resources, therefore is necessary to invent a kind of energy-saving pneumatic liquid discharging valve of effective minimizing gas consumption.

Summary of the invention

The purpose of the utility model is the energy-saving pneumatic liquid discharging valve of a kind of effective minimizing gas consumption of designing for the deficiency that solves above-mentioned technology.

The energy-saving pneumatic liquid discharging valve that the utility model designed; Comprise air cavity; On air cavity, be provided with suction port and air outlet; The air cavity bottom is a pedestal, also is provided with ball float, floating ball rod, floating ball lever, lever connecting rod, flap, flap lever in the said air cavity, and said pedestal is provided with structural poles, spring, flap lever pole, flap lever seat and drain opening; It is hinged that said floating ball rod upper end connects ball float, lower end and floating ball lever, and the other end of floating ball lever and structural poles upper end are hinged; Said lever connecting rod upper end is hinged with floating ball rod, lower end and flap lever one end are hinged, and the said flap lever the other end is arranged on the flap lever seat; Said spring upper end is connected with the flap lever; Said flap lever pole is supported lower Disc lever below; Said flap is arranged on the flap lever and is relative with said drain opening.

The energy-saving pneumatic liquid discharging valve that the utility model designed, under initial situation, the pulling force acting in conjunction of compressed-air actuated pressure and spring makes the flap lever that a downward power arranged, thereby makes flap be sealed on the drain opening.Along with the rising of water level in the air cavity, ball float floats gradually, and floating ball lever is upwards action of fulcrum with the structural poles; Thereby the end at the flap lever forms a pulling force, and along with water level rises gradually, the buoyancy of ball float increases gradually; The pulling force of flap lever end is also increased gradually, and when this pulling force during greater than the pulling force of compressed-air actuated pressure and spring, the flap lever is that fulcrum upwards lifts with the flap lever seat; Thereby make flap and drain opening break away from and form draining, water level descends thereupon, when drawdown arrives certain degree; Under the acting in conjunction of the pulling force of compressed-air actuated pressure and spring, flap forms again and closes.Therefore in whole process, there is a certain amount of water in the pressurized air bottom, and pressurized air can't be discharged from drain opening, thereby can effectively practice thrift gas consumption; In addition, the power that the buoyancy of ball float is opened as flap has bigger emergentness, and need when having the water level of certain altitude, just can open by flap, so the scouring force during draining is bigger, thereby effectively impurity is gone out drain opening, prevents to pile up to block; This energy-saving pneumatic liquid discharging valve can be applicable to the field of various application of compressed air widely.

Embodiment

Combine accompanying drawing that the utility model is done further to describe through embodiment below.

Embodiment 1:

As shown in Figure 1; The described energy-saving pneumatic liquid discharging valve of present embodiment; Comprise air cavity 1, on air cavity 1, be provided with suction port 2 and air outlet 3, air cavity 1 bottom is a pedestal 14; Also be provided with ball float 5, floating ball rod 6, floating ball lever 7, lever connecting rod 8, flap 9, flap lever 10 in the said air cavity 1, said pedestal 14 is provided with structural poles 11, spring 12, flap lever pole 13, flap lever seat 14 and drain opening 15; It is hinged that said floating ball rod 6 upper ends connect ball float 5, lower end and floating ball lever 7, and the other end of floating ball lever 7 and structural poles 11 upper ends are hinged; Said lever connecting rod 8 upper ends and floating ball rod are 6 hinged, lower end and flap lever 10 1 ends are hinged, and said flap lever 10 the other ends are arranged on the flap lever seat 14; Said spring 12 upper ends are connected with flap lever 10; Said flap lever pole 13 is supported lower Disc lever 10 belows; Said flap 9 is arranged on the flap lever 10 and is relative with said drain opening 15.

The described energy-saving pneumatic liquid discharging valve of present embodiment, under initial situation, the pulling force acting in conjunction of compressed-air actuated pressure and spring 12 makes flap lever 10 that a downward power arranged, thereby makes flap 9 be sealed on the drain opening 15.Along with the rising of water level in the air cavity 1, ball float 5 floats gradually, and floating ball lever 7 is upwards action of fulcrum with structural poles 11; Thereby the end at flap lever 10 forms a pulling force, and along with water level rises gradually, the buoyancy of ball float 5 increases gradually; The pulling force of flap lever 10 ends is also increased gradually, and when this pulling force during greater than the pulling force of compressed-air actuated pressure and spring 12, flap lever 10 is that fulcrum upwards lifts with flap lever seat 14; Thereby make flap 9 break away from drain opening 15 and form draining, water level descends thereupon, when drawdown arrives certain degree; Under the acting in conjunction of the pulling force of compressed-air actuated pressure and spring 12, flap 9 forms again and closes.Therefore in whole process, there is a certain amount of water in the pressurized air bottom, and pressurized air can't be discharged from drain opening 15, thereby can effectively practice thrift gas consumption; In addition, the power that the buoyancy of ball float 5 is opened as flap 9 has bigger emergentness, and need when having the water level of certain altitude, just can open by flap 9, so the scouring force during draining is bigger, thereby effectively impurity is gone out drain opening, prevents to pile up to block; This energy-saving pneumatic liquid discharging valve can be applicable to the field of various application of compressed air widely.
