Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
According to People's Republic of China's oil and gas industry standard " petroleum storage tank inhalation valve " SY/T 05511-1996, select inhalation valve operation pressure B level, i.e. malleation 980Pa, between negative pressure-295Pa.The inhalation valve that current domestic oil terminal oil storage tank uses mostly is mechanical type inhalation valve.Unreliable in order to solve conventional camber of spring power, unabiding situation, the utility model have employed magnetic force to replace camber of spring power, selects the N38 permanent magnet of southwestern nuclear industry Research Institute, and this magnet magnetic force is strong, and year demagnetization rate is less than 0.03%, and reliability is high.
As shown in Figure 1 and Figure 2, concrete structure of the present utility model is: valve body 1 upper end is provided with valve gap 15, and there is ventilation space between valve body 1 and valve gap 15, described valve body 1 bottom is fixed with annular brace 2 along its internal surface, annular brace 2 is placed with the valve disc seat of honour 6, is fixed with sleeve 14 perpendicular to center, the described valve disc seat of honour 6, in sleeve 14 inside through a round bar 13, described round bar 13 lower end is fixed with valve disc 4, and described valve disc 4 is slightly less than annular brace 2 opening; Also be provided with magnetic receiver, described magnetic receiver is made up of magnetic receiver top 9 and the magnetic receiver bar 8 being fixed on center, magnetic receiver top 9; Described magnetic receiver bar 8 is connected with round bar 13 upper end, magnetic receiver top 9 is fixed with the second magnet 10, the first magnet 12 is provided with below described second magnet 10, described first magnet 12 to be fixed in sleeve 14 and to repel each other with the second magnet 10, and described sleeve 14 is placed in the circular groove of valve gap 15 center.
For ease of the installation between magnetic receiver bar 8 and round bar 13, described magnetic receiver bar 8 and the connection between round bar 13, for being threaded, magnetic receiver bar 8 have outside thread, and round bar 13 upper end has internal thread, during installation, aligns and tightens.
Control conveniently there is better precision to make the utility model device at air pressure, the lower end of described round bar 13 is provided with the first counterweight 3, on described magnetic receiver bar 8, second counterweight 11 can also be also installed, these two counterweights be combined with each other, or regulate any one balance weight and all can arrive requirement.
The described valve disc seat of honour 6 lower surface is provided with valve disc mat 5, adopts this kind of design, improves the sealing between the valve disc seat of honour 6 and annular brace 2.The described valve disc seat of honour 6 upper surface is provided with valve disc top race 7.
Magnetic type tank valves pilot pressure is by valve disc assemblying body gravity G or magnetic force F
c.When valve disc 4 is in threshold state, equilibrium equation is:
In formula, P
1, P
2be respectively the inside and outside surface gas pressure of valve disc 4, D is valve disc 4 diameter, and G is valve disc assemblying body gravity, and valve disc assemblying body comprises all parts described in the part numbers 3 to 14 in Fig. 1.F
cfor magnet magnetic force.
When valve disc 4 works, its ventilation form may have two kinds:
Work as P
1>P
2time, and
time, valve disc assemblying body upwards rises exhaust, when being vented to
after, valve disc assemblying body declines, and closes inhalation valve, as shown in Figure 5.
Work as P
1<P
2time, and
time, valve disc 4 moves downward air-breathing, when air-breathing arrives
after, valve disc 4 gets back to original position, closes inhalation valve, as shown in Figure 6.
Because valve body 1 and critical piece adopt cast aluminium alloy material, expiration valve disc and air-breathing valve disc are united two into one, realize single valve dish, single channel design, this inhalation valve, compared with domestic like product, has beautiful shape, and structure is simple, overall weight is light, and corrosion resistance is strong, the advantages such as long service life.
Adopt the permanent magnet of national defence nuclear industry, magnetic force is strong, and year demagnetization rate is low.Replace spring force with magnetic force, solving spring time has grown the problem lost efficacy.Moving part and sealing position adopt polytetrafluoroethylmaterial material, sealing reliability improves greatly, and this inhalation valve Long-Time Service still can keep large breathing flexibly and little respiration capability, and sensitivity is high, positive/negative pressure is easy to adjust, simultaneously can low temperature resistant, antifreeze, do not freeze; Easy maintenance, a little repair.
