Description
Technical field
The invention belongs to valve technology field, be specifically related to a kind of high volume pipe abruption valve.
Background technique
The application of Pull breaking ualve and popularization have related to a lot of relevant industries, and the Pull breaking ualve product that is used for all trades and professions at present has a variety of.Say from function; The purpose that requires Pull breaking ualve finally to reach is to be reduced to minimum for fear of the probability that high-risk accident maybe will take place with the generation that prevents security incident, to Pull breaking ualve break performance, sealability, reliability and stability requirement after breaking be higher; Say technically; The technical performance of present whole Pull breaking ualve industry and universal performance also are not very ripe; The application of mainly being presented as Pull breaking ualve is changeable; And majority is to design and produce to single requirement, also has that to be applied to the applicability of multiple environment or medium with a kind of Pull breaking ualve lower, and the versatility that mainly shows as aspects such as working environment, operating temperature, working medium and special industry, particular surroundingss all has certain narrow limitation; Say from structure; The Pull breaking ualve that is used for industry-by-industry, various particular job environment, various working medium occasions and various performance requirements structurally all has certain difference, is mainly reflected in the realization of working environment, medium, latus rectum size, material, dismounting technical requirements and additional other function that each parts adopted.
Because environmental pollution, gas price is reason such as risings constantly in the different regions of China, and the taxi that many automobiles, especially frequency of utilization time are grown has all made compressed natural gas into basically as power fuel.But compressed natural gas has higher pressure, and each pipeline all requires fastening reliable the connection in aerating and the using process.In actual aerating process, can occur also not closing under the situation that adds air valve after automobile does not add gas or aerating completion, automobile slides suddenly or starts, and causes natural gas leaking to such an extent as to break the aerating flexible pipe.Because rock gas has pressure height, inflammable, volatilization characteristics such as fast, natural gas leaking can cause serious consequence.Though situation that pipeline breaks occurs seldom, the moment of breaking the back or breaking, if there is not protective gear, the consequence that causes is inconceivable, the aerating scene reaches after certain concentration of natural gas even can produce the danger of blast.
Summary of the invention
The objective of the invention is to overcome the situation of above-mentioned technical deficiency; At this a kind of tubular type Pull breaking ualve is provided, this tubular type Pull breaking ualve utilizes pressure balance principle, promptly in flexible pipe, has under the situation that fluid passes through; To the Pull breaking ualve two ends apply >=during the pulling force of 600N (pull-off force is adjustable); The separation of Pull breaking ualve meeting automatic safe is broken off, and forms the automatic hermetically closing in two ends, and no flowing medium leaks.Can on the high pressure hose below the 25MPa, play and break protective action, have also simultaneously that pull-off force is reliable and stable, flow is big, maintenance cost is low, easy to maintenance, reusable.And balance cavity 27 exposed on the inlet valve can solve the icing unbalance problem of valve body self that causes under the low-temperature condition reliably; The position structure of being made up of plane one-way valve, Stainless Steel Ball and inlet valve can effectively prevent fluid impact, makes the valve body balance and stability.With inlet valve, setting sleeve, plane one-way valve and break the fluid passage that axle forms and after breaking, can seal fast and effectively, advantage such as limited flow and leakage rate are few.Can avoid generation reliably because of serious consequences such as the escape of liquid that can not effective seal after breaking to cause or blasts.

Working principle
Normal working: when fluid is introduced fluid passage 20 through the inlet valve tapped hole; Flowing out inlet valve introduces and cooperates passage 21 between setting sleeve and the balance one-way valve; Introduce the radial fluid passages 22 of breaking axle again; Introducing is broken the 23 promotion nonreturn valve core displacements of axial flow body passage and is made length of spring compressed once more; This moment nonreturn valve core with break axocoel body sealing surface and separate and form the fluid passage, the passage that fluid is drawn in the middle of the spring seat through the auxiliary hole of nonreturn valve core conical surface gets into the structure that the high-voltage explosion-proof flexible pipe forms a population equilibrium.
Break working state: break parts such as axle, guard shield, seal ring, support ring, nonreturn valve core when the moment that stretch break method is broken and simultaneously separate disconnection fully under with the fast moving of high pressure hose with setting sleeve at automobile; The plane one-way valve promotes to move forward under the effect of hydrodynamic pressure and Returnning spring simultaneously; Make the end face of one-way valve seal ring form quick the contact with the interior resonator end surface protrusion arc surface of setting sleeve; Form sealing state, block the flowing medium of introducing from inlet valve.Simultaneously in the inside cavity of breaking axle because nonreturn valve core receives the promotion of backpressure fluid and Returnning spring, also reverse conical surface that makes nonreturn valve core and the inner chamber body end face formation sealing state of breaking axle of moving blocked reverse leakage.
