Description

Auto-pneumatic cylinder crosses water gas stoper
Technical field
The present invention relates to fire water supply equipment technical field, specifically a kind of auto-pneumatic cylinder crosses water gas stoper.
Background technology
As everyone knows, fire water supply equipment is normally by auto-pneumatic cylinder, air compressor machine, drainage pump and nitrogen cylinder composition, auto-pneumatic cylinder top is provided with water inlet, safety valve, air inlet and pressurization hole, lower end is provided with delivery port, water inlet on auto-pneumatic cylinder is through seal cap sealing, air compressor machine is connected with the pressurization hole of auto-pneumatic cylinder through one way valve, nitrogen cylinder is connected with the air inlet of auto-pneumatic cylinder through pressure regulator valve, drainage pump is connected with delivery port through outlet pipe, due to fire water supply equipment in use, must ensure to fire-fight by water, and avoid gas draining to encourage flame, so be usually provided with gas stoper on described delivery port, the employing float-ball type air-stopping valve that existing gas stoper has is to stop gas, its deficiency is in use because whole long period of soaking that lose of float-ball type air-stopping valve are in water, its valve rod is easy to occur corrosion and stuck, cause use extremely unreliable, some employings are provided with water inlet pipe in the delivery port upper end of auto-pneumatic cylinder, water inlet pipe side is provided with flow inlet, ball float is provided with in water inlet pipe, its deficiency is: unreasonable structure, when fireman opens valve fast, ball float is easy to shift ball float onto delivery port under the impact of the water of flow inlet, cause blocking delivery port, and incur loss through delay fire fighting.
Summary of the invention
The object of the invention is to solve above-mentioned the deficiencies in the prior art, provide that a kind of structure is simple, easy to use, easy to maintenance, the auto-pneumatic cylinder of long service life crosses water gas stoper.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of auto-pneumatic cylinder crosses water gas stoper, be provided with auto-pneumatic cylinder, outlet pipe and ball float, it is characterized in that being provided with only air cylinder and end cap, delivery port in described auto-pneumatic cylinder is fixed with only air cylinder, only air cylinder lower end is fixedly connected with end cap, upper surface is departed from center and is provided with ventilation eyelet, to make there is not gas pressure in cylindrical shell, in the middle part of sidewall, circumference is provided with flow inlet, only be provided with ball float in air cylinder, end cap central is provided with water export, outlet pipe is fixedly connected with end cap, the diameter of described water export is less than floating ball diameter, when press water sprays rapidly under the pressure of the gas, press water enters through flow inlet and stops in air cylinder, ball float only in air cylinder is at the thrust float downward upwards of press water, ball float is made to rest on only air cylinder top, because only air cylinder top is provided with ventilation eyelet, press water only has water in a small amount to impact the edge of ball float through ventilation eyelet, at this moment, ball float can only rotate under buoyancy and less tangential effect, can not downstream blocking delivery port, after the water in tank body extremely can not make ball float float less, ball float will under the acting in conjunction of gravity and gas pressure, rapidly delivery port is sealed, and sealing is tighter.
The acute angle that delivery port on end cap of the present invention contacts with ball float is fillet, to avoid losing ball float, reaches that sealing performance is high, the effect of long service life.
The present invention, owing to adopting said structure, has the advantages such as structure is simple, easy to use, easy to maintenance, long service life.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Fig. 2 is A enlarged diagram of the present invention in Fig. 1.
Reference numeral: auto-pneumatic cylinder 1, outlet pipe 2, ball float 3, only air cylinder 4, end cap 5, ventilation eyelet 6, flow inlet 7, water export 8.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further described:
As accompanying drawing 1, embodiment shown in 2, a kind of auto-pneumatic cylinder crosses water gas stoper, be provided with auto-pneumatic cylinder 1, outlet pipe 2, ball float 3, only air cylinder 4 and end cap 5, delivery port in described auto-pneumatic cylinder 1 is fixed with only air cylinder 4, only air cylinder 4 lower end is fixedly connected with end cap 5, upper surface is departed from center and is provided with ventilation eyelet 6, gas pressure is there is not to make to stop in air cylinder 4, in the middle part of sidewall, circumference is provided with flow inlet 7, only be provided with ball float 3 in air cylinder 4, end cap 5 center is provided with water export 8, outlet pipe 2 is fixedly connected with end cap 5, the diameter of described water export 8 is less than ball float 3 diameter, when press water sprays rapidly under the pressure of the gas, press water enters through flow inlet and stops in air cylinder 4, ball float 3 only in air cylinder 4 is at the thrust float downward upwards of press water, ball float 3 is made to rest on only air cylinder 4 top, because only air cylinder 4 top is provided with ventilation eyelet 6, press water only has water in a small amount to impact the edge of ball float 3 through ventilation eyelet 6, at this moment, ball float 3 can only rotate under buoyancy and less tangential effect, can not downstream blocking delivery port, after the water in auto-pneumatic cylinder 1 extremely can not make ball float 3 float less, ball float 3 will under the acting in conjunction of gravity and gas pressure, rapidly delivery port is sealed, and sealing is tighter, the acute angle that delivery port on end cap of the present invention contacts with ball float is fillet, to avoid losing ball float, reach sealing performance high, the effect of long service life.
The present invention in use, open fire-fighting delivery port, press water in auto-pneumatic cylinder 1 will spray rapidly under the pressure of the gas, in the process of water spray, owing to stopping air cylinder 4 top base closed, only leave ventilation eyelet 6, enough hydraulic thrusts are not had to make ball float 3 descending, and only have a small amount of water slug ball float 3 edge, and large stock current are rushed in only in air cylinder 4 through flow inlet, a powerful thrust is upwards produced to ball float 3, therefore, ball float 3 is in all the time and stops above air cylinder 4, and delivery port can not be blocked, when the water in auto-pneumatic cylinder be seldom not enough to promote ball float 3 float time, ball float 3 will under the acting in conjunction of gravity and gas pressure, rapid whereabouts and delivery port is shut, greatly ensure that the gas in auto-pneumatic cylinder 1 is discharged through outlet pipe 2, and cause unnecessary fire.
The present invention, owing to adopting said structure, has the advantages such as structure is simple, easy to use, easy to maintenance, long service life.
