Abstract
The invention relates to the technical field of one-way valve, in particular relates to a one-way valve for a gas shock wave soot blower. The one-way valve comprises a valve body, a movable valve plug, a guide rod and a gas-guide disk; the gas-guide disk is arranged in the valve plug and fixedly connected with the valve body; the guide rod penetrates through a through hole in the middle of the gas-guide disk, one end is fixedly connected with the movable valve plug, and the other end is provided with a limiting device; a spring is sleeved on the guide rod between the limiting device and the gas-guide disk, and the spring is in a pre-compression state. A spring reset part is arranged on a non-pressure-bearing surface of the gas shock wave soot blower so that the spring cannot bear the instant pressure; meanwhile, the heated strength is reduced to prevent the elasticity of spring from receding after being heated; and the guide rod is arranged at a reverse direction of a forced and carbon deposition direction of the movable valve plug, so that the movable valve plug can accurately reset without a gap, and the problem that the non-return function is failure since the reverse sealing is bad caused by the carbon deposition is avoided.
Description
Technical field
The present invention relates to the one-way valve technical field, be specifically related to a kind of one-way valve that is used for the gas shock-wave ash blowing device.
Background technique
The one-way valve purpose is to prevent that the medium back flow in the pipeline is widely used in liquid, the gas normal pressure pipeline.One-way valve of the prior art is applied on the gas shock-wave ash blowing device, and it is not in place to cause the movable spool of one-way valve to return, and causes one-way valve to lose efficacy.The concrete reason that one-way valve lost efficacy is: existing one-way valve designs be spring at the reverse pressure-bearing face, be exposed to fuse primer flame and partly make the spring hardness that is influenced by heat, thus ineffective; Thereby guide rod be exposed to produce after the detonation of mixed gas part carbon distribution block guide rod and pilot hole stiff cause poorly sealed; It is not in place that the ignition point deflagration pressure causes one-way valve to reset.The poorly sealed meeting of one-way valve causes flame to turn back in the pipeline of one-way valve front along fuse primer, even can damage solenoid valve, and What is more blocks movable spool, causes pipeline blockage thereby make gas pressure push away not open individual event valve.
Summary of the invention
The object of the present invention is to provide a kind of one-way valve that is used for the gas shock-wave ash blowing device, solved the sealing problem between movable valve core reset and the valve body.
In order to achieve the above object, the technological scheme of the present invention's employing is:
A kind of one-way valve that is used for the gas shock-wave ash blowing device comprises valve body, movable spool, guide rod and air-guide disk; Said air-guide disk is arranged in the said valve body, is fixedly connected with said valve body; Said guide rod passes the through hole in the middle of the said air-guide disk, and an end is fixedly connected with said movable spool, and the other end is provided with limit stoper; Be arranged with spring on the guide rod between said limit stoper and the said air-guide disk, said spring is an its pre-compressed state.
In the such scheme, said limit stoper comprises jump ring and buting iron, and said jump ring is fixed on the said guide rod, and said spring precompression is arranged between said buting iron and the said air-guide disk, and said buting iron holds out against through said spring and said jump ring.
In the such scheme, said limit stoper comprises pin and buting iron, and on said guide rod, said spring precompression is arranged between said buting iron and the said air-guide disk said buting iron through dowel fixes.
In the such scheme, the surface of contact of said air-guide disk and said movable spool is provided with chamber.
In the such scheme, said air-guide disk is provided with gas port, and said gas port is oblique through hole.
Compare with the existing technology scheme, the beneficial effect that the technological scheme that the present invention adopts produces is following:
The present invention partly has been placed on the non-pressure-bearing surface of gas shock-wave ash blowing with spring reset, makes spring can not bear instantaneous pressure, has also reduced heat intensity simultaneously, has avoided the spring back elasticity attenuation that is heated;
The present invention with guide rod be arranged on that movable spool is stressed, carbon distribution in the other direction, make that movable valve core reset is accurate, can not leave the slit, avoid carbon distribution etc. to cause the problem of reverse poorly sealed check disabler.
