Abstract
The utility model relates to a tee joint T check valve, which mainly comprises a tee joint T body C, and is characterized in that the utility model is provided with a glide valve core 2 with buffer, as well as a regenerated air-volume controlling valve 7, wherein, the tee joint T body C is provided inside with three air cells 1, 4 and 5, which are respectively connected with flanges 8, 3 and 6, the glide valve core 2 with buffer is arranged inside the air cell 4, both ends of the regenerated air-volume controlling valve are respectively connected with the air cells 1 and 5. The utility model integrates two ordinary check valves, an air outlet tee joint T and the regenerated air-volume controlling valve into a whole, and has the advantages of adjustable regenerated air volume, compact structure, easy assembly, low compact, reliable function with use tolerance, good sealing efficacy, and agile action, etc, compared with the prior art, the utility model can make the drying have device more reliable function, more beautiful, compacter structure and much more economized cost.
Description
Technical field:
The utility model relates to a kind of threeway safety check.
Background technique:
In no hot absorbed type drying device, the prevention dry gas that generally adopts is in the three-way pipe both sides of giving vent to anger a safety check to be installed respectively from the non-return mechanism that work tower flows to regenering tower at present.The kind of this type of safety check is many, and the valve size of some kind is big, causes the exsiccator overall structure not attractive in appearance; The safety check of some kind is unreasonable because of structure, and the impact force that is subjected to during work is excessive, causes valve plate easy-rupturing, poor reliability, influences the normal operation of drying apparatus; Aspect the adjusting of regeneration tolerance, what have adds a bypass at three-way pipe, and modulating valve is installed in bypass, makes the drying apparatus pipeline too complicated like this; The directly perforate on the safety check valve plate that has, but regeneration tolerance is unadjustable.In addition, because parts are many, workload is big when drying apparatus is assembled.
Summary of the invention:
The purpose of this utility model provides a kind of threeway safety check, and it can overcome the deficiencies in the prior art.
The utility model is achieved in that it mainly is made up of three way valve C, it is characterized in that having band snubber slide movable valve plug 2, regeneration gas adjustable valve 7, and in three way valve C, have three air chambers 1,4,5, these three air chambers 1,4,5 are adpting flange 8,3,6 respectively, band snubber slide movable valve plug 2 is in the air chamber 4, and the two ends of regeneration gas adjustable valve 7 connect air chamber 1,5 respectively.
The utility model becomes one two common safety check, the three-way pipe of giving vent to anger, regeneration gas adjustable valve, compared with prior art, have that adjustable, the compact structure of regeneration tolerance, simple installation, impact force are little, reliability and durability, good airproof performance, characteristics such as be active in one's movements, can make during application that drying apparatus more reliable performance, profile are more attractive in appearance, more compact structure, cost more save.
Description of drawings:
Fig. 1 is structure of the present utility model and the application implementation figure in no hot adsorption dry device
Embodiment:
As shown in Figure 1, the utility model mainly is made up of three way valve C, it is characterized in that having band snubber slide movable valve plug 2, regeneration gas adjustable valve 7, and in three way valve C, have three air chambers 1,4,5, these three air chambers 1,4,5 are adpting flange 8,3,6 respectively, band snubber slide movable valve plug 2 is in the air chamber 4, and the two ends of regeneration gas adjustable valve 7 connect air chamber 1,5 respectively.
During work, left tower body A, steam outlet pipe, the right tower body B with the outside is connected with flange 8,3,6.The first, pressurising: under original state, left side tower body A, right tower body B pressurising, this moment, malaria entered exsiccator D from suction flange 10, and enter left tower body A, right tower body B respectively through flange 9,11, after left tower body A, right tower body B adsorption dry, enter simultaneously in the three way valve C by flange 8,6 respectively, and the dry gas of flange 3 outputs by exporting, when two tower body pressure reached rated working pressure, the pressurising process was finished; Second, left side tower body A work, right tower body B regeneration: program controller (13) energising, instruct the interior gas of right tower body B to be discharged in the atmosphere through silencing apparatus 12, and wet air enters left tower body A from flange 10 continuously, this moment left tower body A pressure height, right tower body B pressure is low, under the draught head effect, band snubber slide movable valve plug 2 moves right air chamber 4 and air chamber 5 is separated, most of dry gas can only be through flange 3 outputs of outlet, and the fraction dry gas enters air chamber 5 from air chamber 1 through regeneration gas adjustable valve 7, flow into right tower body B through flange 6 again, pass through sorbent from top to down, make moisture content in the sorbent deviate from and be discharged in the atmosphere by silencing apparatus 12 with air-flow, this moment, right tower body B was in the regeneration stage; The 3rd, right tower body B work, left side tower body A regeneration: left tower body A has worked a period of time, after right tower body B finishes pressurising, gas in the left tower body A of program controller 13 instructions is discharged in the atmosphere through silencing apparatus 12, and wet air enters right tower body B from flange 10 continuously, this moment right tower body B pressure height, left side tower body A pressure is low, under the draught head effect, band snubber slide movable valve plug 2 is moved to the left air chamber 1 and air chamber 4 is separated, most of dry gas can only be through outlet(discharge) flange 3 outputs, and the fraction dry gas enters air chamber 1 from air chamber 5 through regeneration gas adjustable valve 7 and flows into left tower body A through flange 8 again and pass through sorbent from top to down, make moisture content in the sorbent deviate from and be discharged in the atmosphere by silencing apparatus 12 with air-flow, right tower body B work this moment, left side tower body A regeneration so moves in circles, thereby guarantees the normal continuously operation of drying apparatus.
