Description
Technical field:
This utility model relates to a kind of explosion-proof valve, particularly to a kind of gas engine air inlet pipe explosion-proof valve.
Background technology:
Air inlet pipe explosion-proof valve is a kind of important safety of gas engine gas handling system.Burning mixture is in air inlet pipe one
Denier is exploded, and will result in serious economic loss and casualties.Installing after explosion-proof valve, high temperature and high pressure gas can in time from
Discharge at explosion-proof valve, it is to avoid the generation of explosion accident, ensured the safe operation of gas handling system.At present, gas starts
The technical disadvantages that machine exists with air inlet pipe explosion-proof valve: 1, the sealing member of explosion-proof valve is big with fuel gas contact area, in fuel gas
Often containing corrosive gas such as H2S, NH3, make sealing member go bad, follow the string and even ftracture；2, pressed off when explosion-proof valve
Qi Shi, high temperature and high pressure gas impact sealing member, sealing member, because of accelerated ageing of being heated, causes sealing member be full of cracks to damage；3, bullet is lacked
Spring stopping means, when explosion-proof valve is opened, spring is excessive because being stressed, and decrement has exceeded spring-compressed limit, spring pitch
Change, cause spring breaking down, elastic failure, cause explosion-proof valve seal failure.
Utility model content:
This utility model main purpose is to provide one can overcome drawbacks described above, it is ensured that the gas of service life and reliability is sent out
Motivation air inlet pipe explosion-proof valve.
Gas engine air inlet pipe explosion-proof valve provided by the utility model, including valve seat, guides the tip of the axis and is arranged on valve seat
On, the axis body of the axis of guide is provided with resetting-mechanism, the axis of guide is fixed with valve gap with the contact position of valve seat, valve gap and valve seat it
Between be provided with rectangular seal bar；It is provided above detent mechanism at resetting-mechanism.
Described resetting-mechanism includes spring, spring retainer cylinder, and one end of spring is fixed on valve gap, and the other end passes through spring base
Being fixed in spring retainer cylinder, spring retainer cylinder is fixed on the top of the axis of guide；It is provided above detent mechanism at spring retainer cylinder.
Described detent mechanism includes stop nut and the adjusting nut being arranged side by side.
On described valve gap and valve seat, the annular protrusion and annular groove being mutually matched, annular protrusion and the handing-over of annular groove are set
Place is provided with chamfering, and rectangular seal bar is pressed in annular groove by annular protrusion.
Rectangular seal bar is arranged in the annular groove of fixed valve seat, prevents rectangular seal bar to be subject to because of mobile strong
Vibration causes loose or dislocation；Rectangular seal bar is fixed in annular groove by the annular protrusion of valve gap, thus sealing member the most not with enter
Tracheal strips contacts fuel gas, when explosion-proof valve is opened, rectangular seal bar is not impacted by high-temperature gas；Annular protrusion and annular groove
The chamfering of upper setting, it is to avoid explosion-proof valve is stuck when resetting, the problem efficiently solving explosion-proof valve seal failure；Pacify on the axis of guide
Spring-loaded position-limiting drum and stop nut, adjusting nut adjustable amount of spring compression, regulation is diffused pressure, is entered by stop nut
Row location, fasten locking；Spring retainer cylinder can limiting valve cap open time aperture, protection spring without damage.
The beneficial effects of the utility model are:
Rational in infrastructure, easy to use；The service life of explosion-proof valve can be greatly improved, and the use effect of explosion-proof valve can be greatly improved
Really.And making cost and use cost is low, fault rate is few, it is simple to safeguard.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings and this utility model is described in further detail by embodiment:
Fig. 1 is this utility model structural representation；
In figure, 1, valve seat；2, rectangular seal bar；3, valve gap；4, spring；5, spring retainer cylinder；6, the axis of guide；7、
Stop nut；8, adjusting nut；9, spring base.
Detailed description of the invention
As it is shown in figure 1, gas engine air inlet pipe explosion-proof valve provided by the utility model, including valve seat 1, rectangular seal bar
2, valve gap 3, spring retainer cylinder 5, stop nut 7, valve seat 1 is arranged on air inlet pipe end face, and the axis of guide 6 is fixedly mounted on valve
On seat 1, the axis of guide 6 and valve gap 3 be matched in clearance, on the axis of guide 6 equipped with valve gap 3, spring 4, spring retainer cylinder 5, prevent
Pine nut 7, adjusting nut 8, spring base 9；Adjusting nut 8 adjustable spring 4 decrement, pressure is diffused in regulation, by anti-
Pine nut 7 carries out positioning, it is locking to fasten；Rectangular seal bar 2 is fixed in the annular groove of valve seat by the annular protrusion of valve gap,
Utilize the elastic force of spring 4 by rectangular seal bar 2 and valve seat 1 pressing, it is achieved the sealing function of explosion-proof valve.
When there is explosion time in air inlet pipe, valve gap 3 is displaced outwardly along the axis of guide 6, and rectangular seal bar 2 remains fixed in valve seat 1
In annular groove, it is to avoid the high vibration impact on rectangular seal bar 2 performance, the rectangular seal bar 2 can be avoided by high temperature simultaneously
Gas impacts；Spring retainer cylinder 5 can the aperture of limiting valve cap 3, protection spring 4 is without damage；Gases at high pressure are at explosion-proof valve
Discharging, air inlet intraductal pressure constantly reduces, it is therefore prevented that air inlet pipe endogenous cause of ill pressure is excessive and explodes；Valve seat 1 and valve gap 3
Annular groove and annular protrusion all have chamfering, make valve gap 3 smooth and easy reset under the effect of spring 4, again with rectangular seal bar 2
Pressing, has recovered sealing property.By improving the sealing structure of explosion-proof valve, it is to avoid sealing member contacts with corrosive gas,
Avoid high-temperature gas impact sealing member, reduce the probability that rubber seal is rotten, solve when explosion-proof valve resets the most stuck
Problem, provide for spring and be effectively protected, improve the ruggedness of explosion-proof valve.
Above-mentioned case study on implementation is only for understanding this utility model example, and is not the limit to this utility model embodiment
Fixed.To belonging to obvious change or variation that spirit of the present utility model amplified out still in protection model of the present utility model
In enclosing.
