Description

Timing valve formula pressurized air automatic water trap

The utility model relates to a kind of storage of gas or liquid or timing valve formula pressurized air automatic water trap in distribution technique field of belonging to.

In industrial production, pneumatic control is that indispensable constituent element is controlled in industrial automation, and the moisture content in the pressurized air, greasy dirt, iron rust, impurity can cause the corrosion and the obstruction of pneumatic tool, pneumatic equipment, valve, pipeline.Reduce quality of finished, damage equipment and a large amount of repairing maintenance works takes place.In present pressurized air air supply system, enterprise's refrigerated type air dryer commonly used or adsorption air dryer purify source of the gas.For these two kinds of dried-air driers, because the influence of the moisture content in the pressurized air, greasy dirt, impurity composition, filter core stops up, sorbent lost efficacy often to cause interior the crossing of dried-air drier.Therefore, be in operation and want frequent clean filter core and novel sorbents more, safeguarding the operation of dried-air drier, thereby increased maintenance workload and spare part expense.In use we find to cause the increase of water content and greasy dirt in the pressurized air, main cause is that moisture content and the greasy dirt in the compressed air system can not in time discharge, thereby isolated moisture content, greasy dirt, impurity collect in the pressurized air in air press and air gas tank, under compressed-air actuated effect, bring steam line into air.And at present because dried-air drier is worth tens thousand of units to hundreds thousand of units, so most of air supply systems do not dispose dried-air drier, moisture content in the pressurized air, greasy dirt, bringing into of impurity will directly be endangered the air feed source of the gas like this, so in the maintaining work of equipment, require the management of operational administrative personnel reinforcement to air compressor and air gas tank row work.Freezing of moisture content of separation all has a strong impact on compressed air quality in the untimely discharging of moisture content and the air gas tank bottom discharge pipe under the winter low temperature environment but because administrative staff separate with the air gas tank air compressor.At present domestic suitable compressed-air actuated automatic draining dehumidifying purification plant.

The purpose of this utility model provides a kind of timing valve formula pressurized air automatic water trap for solving disadvantages of background technology exactly.

The purpose of this utility model is achieved in that it mainly is made up of tee union, the waste pipe that catchments, timing drain solenoid valve, tee union by the threeway cylinder body, be fixed on the inboard nonmetal fixing frame of threeway cylinder body one end, be fixed on the fixing frame two metal probe bars and sealing cover is formed, termination air gas tank on the tee union, another termination waste pipe water inlet pipe that catchments, the waste pipe that catchments is the garden post cavity of horizontal positioned, its two ends are provided with water inlet pipe and waste pipe, waste pipe connects the timing drain solenoid valve, and the timing drain solenoid valve is provided with timing circuit.

The purpose of this utility model also can realize like this: it mainly is made up of tee union, vortex type moisture trap, timing drain solenoid valve, the vortex type moisture trap is by upright cavity, the suction tude and the steam outlet pipe that are connected with upright cavity, the spirally-guided blade that is arranged on middle part in the upright cavity is formed, upright cavity end portion is tapered to be narrowed, tee union is installed in the sidewall outside, upright cavity lower end, and the timing drain solenoid valve is installed in the upright cavity bottom outside.

The utility model is compared background technique and had following advantage: 1, accommodation is big, applicable to air compressor, the air gas tank of all size; 2, need not install filter screen, need not the disassembly, cleaning maintenance, but the automatic timing blowdown greatly reduce maintenance workload, has improved compressed-air actuated source of the gas quality.

Fig. 6 is the timing circuit schematic diagram.

The utility model is further described by embodiment below in conjunction with accompanying drawing: as shown in Figure 1, the utility model is applied in the air gas tank, in air gas tank bottom the tee union 1 of sensed water level, the waste pipe 2 that catchments, timing drain solenoid valve 3 is installed.The moisture content that the air gas tank separates, greasy dirt, impurity collects in air gas tank bottom, collection full water part in the waste pipe 2 that catchments, greasy dirt, behind the impurity, the metal probe bar is connected by liquid in the tee union 1, timing drain solenoid valve 3 obtains opening automatically behind the signal that the metal probe bar connected by liquid, and pick up counting, under compressed-air actuated pressure effect, moisture content in the waste pipe 2 catchments, greasy dirt, impurity begins quick drain, treat the isolated moisture content of air reservoir bottom pressurized air, greasy dirt, after the impurity emptying, 3 timing of timing drain solenoid valve finish and close automatically, finish the automatic discharging that the primary air gas tank separates moisture content.As shown in Figure 4, the timing drain solenoid valve is made up of timing circuit and two three-way electromagnetic valves.As Fig. 2, shown in Figure 3, threeway probe 1 is made up of threeway cylinder body 7, sealing cover 4, metal probe bar 5 and nonmetal fixing frame 6.The catchment water inlet pipe 12 of waste pipe 2 of one termination air gas tank of threeway probe 1, another termination, the outlet pipe 13 of the waste pipe 2 that catchments connects timing drain solenoid valve 3.As shown in Figure 5, use terminal at pressurized air, by the vortex type moisture trap be as the working principle of bellows chamber, utilize the power of pressurized air itself, the pressurized air that enters bellows chamber is rotated down along spirally-guided blade 11, make airborne moisture content, greasy dirt, impurity is subjected under the effect of centrifugal force and gravity, throw to upright cavity 9 inwalls of bellows chamber, and be pooled to upright cavity 9 bottoms downwards along inwall, when the moisture content that separates, greasy dirt, when impurity is collected to the monitoring water level of the threeway probe 1 that is provided with on the upright cavity 9, issue an order to the timing drain solenoid valve 3 automatic drainings that are installed in upright cavity 9 bottoms, upright cavity 9 is provided with suction tude 10 and steam outlet pipe 8.As shown in Figure 6, timing circuit power supply E is the 3V battery, and a, b point is connected for water level detecting point and with two metal probe bars 5 of tee union 1.When water level is connected a, b point, resistance R ₂, capacitor C ₁The time-delay charging circuit of forming is connected, trigger triode V ₁Conducting makes light-operated bidirectional triode thyristor GT conducting then, and electromagnetic valve voltage is connected at its output c, d control point, and the timing drain solenoid valve gets the electric drain valve of opening.Triode V ₁Select 9013 for use, light-operated bidirectional triode thyristor GT selects GTJ series solid-state relay, R for use ₂Be 10K Ω, C ₁Be 220u/6v.
