Detailed description of the invention
Describe the present invention below in conjunction with the accompanying drawings.
Embodiment one
As shown in Fig. 1 to 3 and Fig. 6, the present invention a kind of can the shock wave resistance valve of two-way reset, including valve body 1 and spool
2, connecting rod secondary 3 and return springs 4a, secondary 3 one end of connecting rod are connected with valve body 1 by the first bearing pin 5, and the other end is by the second pin
Axle 6 is connected with spool 2, and return springs 4a one end is resisted against in connecting rod pair 3, the other end be pressed against the second bearing pin 6 and spool 2 it
Between, return springs 4a lateral symmetry, it includes malleation pole 4.1a, negative pressure pole 4.2a, stretch section 4.3a and fixing support
Section 4.4a, malleation pole 4.1a and negative pressure pole 4.2a are connected to enclose and cover into the confession set frame 4.5a that passes of connecting rod pair 3, described negative pressure
Pole 4.2a is resisted against the downside of connecting rod pair 3, and described malleation pole 4.1a is resisted against the upside of connecting rod pair 3；Stretch section 4.3a is V
Font, its one end is connected with described set frame 4.5a, and the other end is connected with described fixing supporting section 4.4a, stretch section 4.3a and set frame
4.5a junction dish becomes helical spring 4.6a, described malleation pole 4.1a to be plugged on the center of helical spring 4.6a；Fixing support
Section 4.4a is M font, and its medial recess is pressed against the second bearing pin 6, and its both sides leg is pressed against on spool 2.
In order to reduce the air flow resistance in ventilation housing 1.1, two ventilation housings 1.1 that valve body 1 is provided with are close to arrange.
Implementation process is as follows:
As in figure 2 it is shown, under normal condition, spool 2 is in the middle part of valve body 1, when spool 2 is by negative pressures, spool 2
Pressed shifting closed valve 1 overdraught mouth closed valve 1 overdraught mouth, the now stretch section 4.3a of return springs 4a
Pressurized compresses, and negative pressure pole 4.2a is pressed against the downside of connecting rod pair 3, is made by the cooperation of negative pressure pole 4.2a and stretch section 4.3a
By, return springs 4a, spool 2 is applied the active force in opposite direction with the negative pressures that spool 2 is subject to, when spool 2 is subject to
When negative pressures disappears, the counteracting force that spool 2 applies is made spool 2 reset in the middle part of valve body 1 by return springs 4a；Work as spool
2 by positive pressure time, spool 2 pressurized moves down closed valve 1 leg space ventilation mouth closed valve 1 leg space ventilation mouth, this recurrence of disease at the same time next year
The stretch section 4.3a stress stretching of position elastic component 4a, malleation pole 4.1a is pressed against the upside of connecting rod pair 3, by malleation pole
4.1a and the mating reaction of stretch section 4.3a, return springs 4a applies the positive pressure direction phase being subject to spool 2 to spool 2
Anti-active force, when the positive pressure that spool 2 is subject to disappears, the counteracting force that spool 2 is applied by return springs 4a makes valve
Core 2 resets in the middle part of valve body 1.
Embodiment two
The embodiment that embodiment two essentially consists in return springs from the difference of embodiment one is different
As Fig. 4 to return springs 4b shown in 5 includes malleation return unit 4.1b and negative pressure return unit 4.2b, malleation return unit
4.1b is a helical spring, and it is plugged on the first bearing pin 5 away from one end that connecting rod is secondary, near one end of connecting rod pair 3 linearly
Extend the secondary lateral buckling of backward connecting rod and be resisted against on the downside of connecting rod pair 3；Negative pressure return unit 4.2b lateral symmetry, it includes that negative pressure is propped up
Bar 4.3b, stretch section 4.4b and fixing supporting section 4.5b, described negative pressure pole 4.3b is resisted against the downside of connecting rod pair 3, described bullet
Property section 4.4b is V-shape, and its one end is connected with described negative pressure pole 4.3b, and the other end is connected with described fixing supporting section 4.5b；
Fixing supporting section 4.5b is M font, and its medial recess is pressed against the second bearing pin 6, and its both sides leg is pressed against on spool 2.
Implementation process is as follows:
As Fig. 4 is to shown in 5, and under normal condition, spool 2 is in the middle part of valve body 1, when spool 2 is by negative pressures, valve
Core 2 is pressed shifting closed valve 1 overdraught mouth closed valve 1 overdraught mouth, the now elasticity of negative pressure return unit 4.2b
Section 4.4b pressurized compression, negative pressure pole 4.3b is pressed against the downside of connecting rod pair 3, by negative pressure pole 4.3b's and stretch section 4.4b
Mating reaction, negative pressure return unit 4.2b applies the active force in opposite direction with the negative pressures that spool 2 is subject to spool 2, works as valve
When the negative pressures that core 2 is subject to disappears, the counteracting force that spool 2 applies is made spool 2 reset to valve body 1 by negative pressure return unit 4.2b
Middle part；When spool 2 is by positive pressure, spool 2 pressurized moves down closed valve 1 leg space ventilation mouth and closed valve 1 bottom leads to
Air port, now malleation return unit 4.1b stress is reversed, and it is pressed against the downside of connecting rod pair 3 near one end of connecting rod pair 3, to connecting rod
Secondary 3 apply the active force in opposite direction with the positive pressure that spool 2 is subject to, when the positive pressure that spool 2 is subject to disappears, and malleation
The counteracting force that connecting rod secondary 3 is applied by return unit 4.1b makes connecting rod pair 3 be lifted up, thus moves on band movable valve plug 2, makes spool 2
Reset in the middle part of valve body 1.
The above is the preferred embodiment of the present invention, for those skilled in the art,
Without departing from the principles of the invention, it is also possible to make some improvement, these improvement are also regarded as protection scope of the present invention.
