Abstract
The invention discloses a large-flux pipe-typed abruption valve, which is characterized in that the large-flux pipe-typed abruption valve comprises an air inlet nozzle, a middle sleeve, an air outlet sleeve, a plurality of O-shaped sealing rings, a sleeve ring, a recovery spring, a balance sleeve, a plurality of supporting rings, a sealing ring, a positioning spring, a positioning steel ball, a protection cover, a check valve core, a positioning clamping spring and a flow guide mechanism. The large-flux pipe-typed abruption valve applies the pressure balance principle, namely, under a situation that pressure fluid is in a soft pipe or the pressure fluid passes through the soft pipe, and when 400-600N of the tensile force is acted on the two ends of the abruption valve, the abruption valve is automatically disconnected safely; furthermore, the two ends of the abruption valve are automatically closed without fluid leakage; therefore, the abruption valve has an abruption protection function on the high pressure soft pipe under the pressure less than 25MPa; as the abruption valve is internally provided with the flow guide mechanism, the flux of the abruption valve can achieve more than 200Nm<3>/min; meanwhile, the large-flux pipe-typed abruption valve has the advantages of stable abruption force, large flux, easy maintenance, repeated application, large flux, etc.
Description
Technical field
The invention belongs to valve technology field, be specifically related to a kind of high volume pipe abruption valve.
Background technique
Owing to reasons such as environmental pollution, the continuous risings of gas price, many automobiles, especially service time, the taxi that frequency is long have all made compressed natural gas basically into and have acted as a fuel in the many places of China.But compressed natural gas has higher pressure, wants pipeline to be fastenedly connected during aerating.For improving inflation reliability, Security.Announce September 26 calendar year 2001, and notification number is CN2450463Y, and name is called the Chinese utility model patent that makes up gas charging valve and discloses a kind of rock gas gas charging valve that protective function is arranged.This combination gas charging valve comprises the stop valve of suction port and air outlet, and cone shaped one-way valve is equipped with in inlet at stop valve.This gas charging valve combines stop valve and one-way valve, cone shaped one-way valve wherein, only allow the rock gas forward to flow into air supply system, and the rock gas in the air supply system can not flow backwards, even stop valve has leakage, because the non-return effect of one-way valve also can prevent natural gas leaking, the reliability of use and the safety of aerating have more been increased.This gas charging valve only prevents to add the effect that rock gas flows backwards.And in actual aerating process, also can occur also not closing under the situation that adds air valve after Automobile air does not add or adds, automobile slides suddenly or starts, to such an extent as to break the aerating pipeline, causes natural gas leaking.Because LNG Liquefied natural gas has pressure height, inflammable, natural gas leaking can cause serious consequence.Though, situation that pipeline breaks appears seldom, and after breaking, if there is not protective gear, the consequence that causes is inconceivable, even the danger that can blast.
Rock gas is canned when going into the gas cylinder of automobile, must use compressed natural gas (CNG) filling machine, along with being extensive use of and the wide spread of CNG gas station of CNG automobile, technical, Security and reliability to the aerating speed of CNG filling machine, filling machine are also had higher requirement, and this just is faced with a series of safety problem.Wherein, the tubular type Pull breaking ualve is as occurring one of dangerous parts easily, and filling machine just may cause the serious consequence that the aerating flexible pipe is broken or filling machine is forgotten about it because of operate miss when giving user's aerating.Therefore, the raising of tubular type Pull breaking ualve flow has become one of bottleneck problem of a restriction filling machine aerating speed.
The present invention has done at this situation.
