Abstract
The utility model discloses a special dryer outlet integration valve for an NGFD natural gas station. The special dryer outlet integration valve comprises a valve body, the valve body is provided with an A tower air outlet and inlet, a B tower air outlet and inlet and a drying air outlet. A spherical channel is arranged in the valve body and respectively communicated with the A tower air outlet and inlet, the B tower air outlet and inlet and the drying air outlet. A non-returning ball is arranged in the spherical channel, and a regeneration air channel is further arranged in the valve body and communicated with the A tower air outlet and inlet and the B tower air outlet and inlet. The non-returning ball can move in the spherical channel and block cone-shaped surfaces of two ends of the spherical channel. The regeneration air channel is provided with a regeneration air regulating valve. A check valve on an A tower outlet, a check valve on a B tower outlet and the regeneration air regulating valve are integrated to be a three-way valve on the basis that working principle and the characteristics of an original structure are not changed, original eight interfaces are reduced to three now, leakage points are reduced, and the special dryer outlet integration valve is simple in integral structure and convenient to install and use.
Description
Technical field
The utility model relates to a kind of valve, the special-purpose dryer export integral valve of especially a kind of NGFD natural gas filling station.
Background technique
The special-purpose exsiccator of existing natural gas filling station adopts two adsorption tower (A tower and B tower) parallel operation modes, when a tower job, while sloughing the moisture in gas, another tower activating and regenerating, two towers hocket and are dried and regenerative process, A tower and the outlet of B tower have an one-way valve He Yi road regeneration gas modulating valve, the dryer export end of this structure has eight interfaces, greatly increased leak point, and this equipment is very high to tightness requirement, therefore reducing interface is comparatively effective method.
Model utility content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of NGFD natural gas filling station simple in structure, easy for installation, that leak point is few special-purpose dryer export integral valve.
For achieving the above object, the technical solution of the utility model is: the special-purpose dryer export integral valve of a kind of NGFD natural gas filling station, comprise valve body, described valve body is provided with A tower give vent to anger suction port, B tower give vent to anger suction port and dry gas outlet, described valve inner is provided with spherical channel, described spherical channel is communicated with respectively A tower give vent to anger suction port, B tower give vent to anger suction port and dry gas outlet, in spherical channel, be provided with check ball, described valve inner is also provided with regeneration gas passage, described regeneration gas channel connection A tower suction port and the B tower suction port of giving vent to anger of giving vent to anger.
Described check ball can move and block the conical surface at spherical channel two ends on spherical channel.
Described regeneration gas passage is provided with regeneration gas modulating valve.
The beneficial effects of the utility model are: do not changing on the working principle of original structure and the basis of characteristic, one-way valve and the regeneration gas modulating valve of A tower and the outlet of B tower are merged into a three-way valve, original eight interfaces are reduced to present three, reduced leakage point, overall structure is simple, easy to install.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: valve body 1, A tower give vent to anger suction port 2, B tower give vent to anger suction port 3, dry gas outlet 4, check ball 5, regeneration gas passage 6, regeneration gas modulating valve 7, spherical channel 8.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
As shown in Figure 1, the special-purpose dryer export integral valve of a kind of NGFD natural gas filling station, comprise valve body 1, described valve body 1 is provided with A tower give vent to anger suction port 2, B tower give vent to anger suction port 3 and dry gas outlet 4, described valve body 1 inside is provided with spherical channel 8, described spherical channel 8 is communicated with respectively A tower give vent to anger suction port 2, B tower give vent to anger suction port 3 and dry gas outlet 4, in spherical channel 8, be provided with check ball 5, described valve body 1 inside is also provided with regeneration gas passage 6, and described regeneration gas passage 6 is communicated with A towers suction port 2 and the B tower suction port 3 of giving vent to anger of giving vent to anger.
Described check ball 5 can move and block the conical surface at spherical channel 8 two ends on spherical channel 8.
Described regeneration gas passage 6 is provided with regeneration gas modulating valve 7.
In using process, when A tower adsorbs, B tower is regenerated, through A tower dried gas, from the A tower suction port 2 of giving vent to anger, enter, promote check ball 5 and block spherical channel 8 near the give vent to anger conical surface of suction port 3 ends of B tower, dry gas is discharged from dry gas outlet 4, can oppositely regenerate by 6 pairs of B towers of regeneration gas passage from the A tower dry gas that suction port 2 enters of giving vent to anger simultaneously, and regeneration gas can be controlled flows by regeneration gas modulating valve 7.When A tower adsorbs, switch to B tower when saturated and carry out adsorptive process and A tower is regenerated simultaneously, principle is the same during with the absorption of A tower, the regeneration of B tower.
The utility model is not changing on the working principle of original structure and the basis of characteristic, one-way valve and the regeneration gas modulating valve 7 of A tower and the outlet of B tower are merged into a three-way valve, original eight interfaces are reduced to present three, reduced leakage point, overall structure is simple, easy to install.
