Description
Technical field
The utility model relates to a kind of air pressure valve, particularly a kind of leading type electric detonation open valve.
Background technique
Along with the continuous development of air pressure application technology, at present, the Environmental Conditions of highpressure, big flow is more and more.Adopt solenoid valve to carry out pneumatic automatic control in most air pressure applied environments mostly, existing solenoid valve major part is made up of pressure spring, piston, push rod and sealing surface, armature and electromagnetic coil etc.Solenoid valve is after receiving control command, and the electromagnetic force that produces by electrical signal makes piston move, and drives push rod and moves, and sealing surface is followed push rod and removed, and the gas passageway reaches the control effect.But well-known, this class valve is in the work down of making a concerted effort of spring force and electromagnetic force, when valve port is bigger, when air pressure was higher, the spring stress of valve body was big, have only the control electric current that increases electromagnet could finish the control action of valve smoothly, and working stability and sealing are relatively poor.
The model utility content
The purpose of this utility model provides a kind of guide's electric detonation open valve, and when working under hyperbaric environment in order to solve existing solenoid valve, the control electric current is big, poor work stability and the bad problem of sealing effect.
For achieving the above object, the utility model adopts following technological scheme: a kind of guide's electric detonation open valve, this valve comprises main valve body, the damping hole that is provided with the spool installation cavity in the main valve body and is communicated with the spool installation cavity, be provided with spool in the spool installation cavity, be positioned at the damping hole place on the described main valve body and be provided with electric explosion valve, described seal spool thrust is installed in the spool installation cavity, and spool is divided into exhaust cavity, air-inlet cavity and guide with the spool installation cavity and controls air cavity; Be provided with the micropore that connection air-inlet cavity and guide control air cavity in the described spool; Described damping hole and guide control air cavity and are conducted, and described damping hole is provided with the outlet nozzle that an end is a cecum near the end sealing of electric explosion valve, and the cecum of outlet nozzle is positioned at the impingement area of raming of electric explosion valve.
Described main valve body is provided with the air pressure monitor device, and the end of probe of this air pressure monitor device is connected with air-inlet cavity.
Described main valve body is provided with inflatable component, unidirectional conducting between this inflatable component and the air-inlet cavity.
The tail end sealing of described spool installation cavity is provided with a spring seat, and the middle part of described spool is provided with the ring platform, presses between described spring seat and the ring platform to be provided with spring.
In the described spool installation cavity, air-inlet cavity and guide control and are provided with boss between the air cavity, and described spool cooperates with the boss thrust by the front-end face of ring platform.
Upwards be provided with O type circle the week of described spool, spool is sealed and matched by O type circle and spool installation cavity
Guide's electric detonation open valve of such scheme is simple in structure, controlled gas and air-inlet cavity are in connected state always, pressurized gas provide sealing load to spool, make gas pressure that this valve controls increase considerably satisfying under the intensity that casing rigidity requires like this, and can not influence the sealing of valve body.In addition, adopt electric explosion valve to carry out leading type control,, also improved the speed of response of this valve simultaneously so even the increase valve port can not influence the command control to this valve yet, this can increase gas flow greatly; Also have, air pressure monitor device on the valve body, this air pressure monitor device is detected gas pressure in real time, and it can transship unloading pressure protection when gas pressure is higher than design load, has increased the Security of this valve so effectively; Also have this valve adopt O type circle structure realize soft seal, change the seal form that traditional soft sealing face moves, adopt O type circle sealing cost low, good sealing effect.
