Description

A kind of special float-ball type self-draining arrangement of hydrogen making machine

【Technical field】

This utility model is related to the technical field of the emptying of hydrogen making machine and hydrogen storage equipment, and particularly a kind of hydrogen making machine is special Float-ball type self-draining arrangement technical field.

【Background technology】

All need to arrange a water seal or valve, in order to arrange on the hydrogen emptying pipeline that traditional hydrogen making machine and hydrogen storage are filled The condensed water in Hydrogen Line is released, but valve needs to control manually, and water seal has numerous defects, water sealed tank must enter daily Row examination and maintenance, to guarantee the water seal height of water sealed tank；When relatively low for temperature, water will produce icing phenomenon, block hydrogen Gas is discharged；Body is larger, interface is more, installs inconvenience.Therefore the method is without the safety that can have a strong impact on system, and detect and The workloads such as maintenance are big, design a kind of novel water discharge device for the problems referred to above and are particularly important.

【Utility model content】

The purpose of this utility model is exactly to solve the problems of the prior art, proposes a kind of special float-ball type of hydrogen making machine certainly Dynamic drainage arrangement, the condensed water that can be automatically drained out on hydrogen supply pipeline, while the leakage of hydrogen effectively can be prevented.

For achieving the above object, the utility model proposes a kind of special float-ball type self-draining arrangement of hydrogen making machine, bag Valve body, water inlet, ball float, manual blowdown mouth, lever, discharge outlet and valve element is included, valve body upper end is provided with water inlet, the water inlet The lowest point of Hydrogen Line is connected to, the valve body lower end is provided with manual blowdown mouth and discharge outlet, and the manual blowdown mouth is located at Discharge outlet left, is provided with piston, is provided with ball float, below the discharge outlet above the manual blowdown mouth in the manual blowdown mouth It is connected with round through hole.

Preferably, the valve element top half is into reverse frustoconic, the valve element the latter half is circular guide pillar, the row Mouth of a river shape is equal into the taper of reverse frustoconic, the discharge outlet and valve element top half inverted round stage, the lower half of the valve element The outer surface of circular guide pillar for dividing leaves the gap of 3～5mm with the inner surface of manhole.

Preferably, water level is higher than discharge outlet upper surface 4cm in the valve body, ball float is because of buoyancy force.

The beneficial effects of the utility model：Ball float is risen by this utility model by product buoyancy of water, while band movable valve plug Water is discharged by rise, and Auto-drainage is frequently checked without the need for operations staff and draining, as in valve body, water level is consistently higher than discharge outlet, Hydrogen gas leakage can be prevented, long service life is easy to maintenance, the condensed water elimination that can be widely used on hydrogen pipeline.

Feature of the present utility model and advantage will combine accompanying drawing by embodiment and be described in detail.

【Description of the drawings】

Fig. 1 is a kind of profile of the special float-ball type self-draining arrangement of hydrogen making machine of this utility model.

In figure：1- valve bodies, 2- water inlets, 3- ball floats, 4- manual blowdown valves, 5- levers, 6- discharge outlet, 7- valve elements, 8- live Plug, 9- manholes.

【Specific embodiment】

Refering to Fig. 1, this utility model, including valve body 1, water inlet 2, ball float 3, manual blowdown mouth 4, lever 5, discharge outlet 6 With valve element 7, valve body upper end is provided with water inlet 2, and the water inlet 2 is connected to the lowest point of Hydrogen Line, and the valve body lower end sets There are manual blowdown mouth 4 and discharge outlet 6, the manual blowdown mouth 4 is located at 6 left of discharge outlet, work is provided with the manual blowdown mouth 4 Plug 8, is provided with ball float 3, is connected with round through hole 9 below the discharge outlet 6 above the manual blowdown mouth 4；7 upper half of the valve element Into reverse frustoconic, 7 the latter half of the valve element is circular guide pillar for part, 6 shape of the discharge outlet into reverse frustoconic, the draining The taper of mouth 6 and 7 top half inverted round stage of valve element is equal, the outer surface and circle of the circular guide pillar of the latter half of the valve element 7 The inner surface of shape through hole 9 leaves the gap of 3～5mm；In the valve body 1, water level is higher than 6 upper surface 4cm of discharge outlet, and ball float is because floating Power floats.

Utility model works process：

A kind of special float-ball type self-draining arrangement of hydrogen making machine of this utility model in the course of the work, in initial period, Ball float 3 in valve body 1 due on valve element 7 during gravity partial outer face be close to 6 inner surface of discharge outlet, when condensed water reach valve body 1 It is interior, while when water level is higher than 6 upper surface 4cm of discharge outlet, ball float 3 is risen because of buoyancy, while by lever 5 with 7 liters of movable valve plug Rise, gap between valve element 7 and discharge outlet 6, occur, condensation aquiform stool is flowed out from discharge outlet 6, when water level is less than 6 upper surface of discharge outlet During 4cm, now ball float 3 declines, and valve element 7 also declines, and is close to discharge outlet 6, and condensed water is not then exhausted from, as water level is less than draining During 6 upper surface 4cm of mouth, valve element 7 is just close to discharge outlet 6, and valve element 7 is consistently lower than water level, can prevent the leakage of hydrogen, work as hydrogen Pipeline is stopped using is, user can by piston 8, manually superfluous water be discharged by sewage draining exit 4 manually.

Ball float 3 is risen by this utility model by product buoyancy of water, while band movable valve plug 7 rises and discharges water, is arranged automatically Water frequently checks without the need for operations staff and draining, as water level is consistently higher than valve element 7 in valve body 1, can prevent hydrogen gas leakage, make Condensed water elimination with life-span length, easy to maintenance, being widely used on hydrogen pipeline.

Above-described embodiment be to explanation of the present utility model, be not to restriction of the present utility model, it is any new to this practicality Scheme after type simple transformation belongs to protection domain of the present utility model.
