Description
Technical field
The utility model relates to fire water supply equipment technical field, and specifically a kind of auto-pneumatic cylinder is crossed 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 form, 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 guarantee to fire-fight by water, and avoid gas draining to encourage flame, so be conventionally provided with gas stoper on described delivery port, the employing float-ball type air-stopping valve that existing gas stoper has stops 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 is stuck, it is extremely unreliable to cause using, some employings are provided with water inlet pipe in the delivery port upper end of auto-pneumatic cylinder, water inlet pipe one side is provided with flow inlet, in water inlet pipe, be provided with ball float, 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, put out a fire.
Summary of the invention
The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art, provides a kind of auto-pneumatic cylinder simple in structure, easy to use, easy to maintenance, long service life to cross water gas stoper.
The utility model solves the technical scheme that its technical problem adopts:
A kind of auto-pneumatic cylinder is crossed 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, on delivery port in described auto-pneumatic cylinder, be 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, so that there is not gas pressure in cylindrical shell, sidewall middle part circumference is provided with flow inlet, only in air cylinder, be provided with ball float, end cap center 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, while spraying rapidly under the pressure of press water at gas, press water enters and stops in air cylinder through flow inlet, only the ball float in air cylinder is at the thrust float downward making progress of press water, make ball float rest on only air cylinder top, owing to stopping air cylinder top, be provided with ventilation eyelet, press water only has water in a small amount through ventilation eyelet, to impact the edge of ball float, at this moment, ball float can only rotate under buoyancy and less tangential effect, can downstream blocking delivery port, water in tank body is less to not making after ball float floating, ball float will be 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 described in the utility model contacts with ball float is fillet, to avoid losing ball float, reaches that sealing performance is high, the effect of long service life.
The utility model is owing to adopting said structure, has the advantages such as simple in structure, easy to use, easy to maintenance, long service life.
accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is A enlarged diagram of the present utility model 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.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated:
As accompanying drawing 1, embodiment shown in 2, a kind of auto-pneumatic cylinder is crossed water gas stoper, be provided with auto-pneumatic cylinder 1, outlet pipe 2, ball float 3, stop air cylinder 4 and end cap 5, on delivery port in described auto-pneumatic cylinder 1, be fixed with only air cylinder 4, only air cylinder 4 lower ends are fixedly connected with end cap 5, upper surface is departed from center and is provided with ventilation eyelet 6, so that only there is not gas pressure in air cylinder 4, sidewall middle part circumference is provided with flow inlet 7, only in air cylinder 4, be provided with ball float 3, end cap 5 centers are 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 diameters, while spraying rapidly under the pressure of press water at gas, press water enters and stops in air cylinder 4 through flow inlet, only the ball float 3 in air cylinder 4 is at the thrust float downward making progress of press water, make ball float 3 rest on only air cylinder 4 tops, owing to stopping air cylinder 4 tops, be provided with ventilation eyelet 6, press water only has water in a small amount through ventilation eyelet 6, to impact the edge of ball float 3, at this moment, ball float 3 can only rotate under buoyancy and less tangential effect, can downstream blocking delivery port, water in auto-pneumatic cylinder 1 is less to not making after ball float 3 floatings, ball float 3 will be 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 described in the utility model contacts with ball float is fillet, to avoid losing ball float, reach sealing performance high, the effect of long service life.
The utility model in use, open fire-fighting delivery port, press water in auto-pneumatic cylinder 1 will spray rapidly under the pressure of gas, in the process of water spray, owing to stopping air cylinder 4 top base closeds, only leave ventilation eyelet 6, do not have enough hydraulic thrusts to make ball float 3 descending, and only there are a small amount of water slug ball float 3 edges, and large strand of current are in flow inlet is only rushed in air cylinder 4, ball float 3 is produced to the powerful thrust making progress, therefore, ball float 3 is all the time in stopping air cylinder 4 tops, and can not block delivery port, when the water in auto-pneumatic cylinder is seldom not enough to promote ball float 3 floating, ball float 3 will be under the acting in conjunction of gravity and gas pressure, fall rapidly and delivery port is shut, greatly guaranteed that the gas in auto-pneumatic cylinder 1 discharges through outlet pipe 2, and cause unnecessary fire.
The utility model is owing to adopting said structure, has the advantages such as simple in structure, easy to use, easy to maintenance, long service life.
