Further, first cover body includes upper cover and cylinder, and the cylinder top is equipped with a circle mounting ring, described
Gasket is equipped between upper cover and the cylinder.
The beneficial effects of the utility model：
(1) relief valve of the utility model, when storage bin internal pressure maintains in the selected pressure value of valve, valve deck is protected
Resting position is held, since one power of pressure generation acts on spool top surface in storage bin, spool is made to be closely contacted on seal receptacle,
To reach sealing；When storage bin pressure buildup to valve select pressure value when, storehouse internal pressure power overcomes spool weight, by spool from
Jacked up on seal receptacle, at the same gas from the gap between spool, gasket enter the first cover body cavity in, until in storage bin
When portion's pressure drops to identical as the selected pressure value of valve, spool returns normal position, and is contacted with seal receptacle, realizes close
Envelope.The good airproof performance of the utility model, simple in structure, high sensitivity can set valve different according to different use environments
Pressure value has a wide range of application.
(2) in the utility model, the outer wall of the second cover body lower part is fixed with baffle, the baffle and first cover body
Between there are gap for gas to pass through, with slow release pressure, with ensure next time when releasing stress, the first cover body, the
There is certain pressure difference, to realize quick pressure releasing in two cover bodies and storehouse.
(3) in the utility model, the both sides of leading rod are symmetrically set in there are two secondary guide rod is set, the effect of secondary guide rod be
During spool moves up and down, the stabilization of valve body is kept, and symmetrically arranged two secondary guide rods, it can further keep stability
And balance.
(4) in the utility model, the second cover body inner wall is fixed with mounting plate, between the mounting plate and the seal receptacle
It is detachably connected, further preferably detachable connection connects for bolt and nut, and detachable connection can facilitate to valve
Pressure value set, it is more adaptable, and maintain easily, or the dust in cleaning relief valve.
(5) in the utility model, in order to improve the leakproofness of relief valve, seal receptacle is equipped with sealing with the spool contact position
Circle；First cover body includes upper cover and cylinder, and the cylinder top is equipped with a circle mounting ring, is set between the upper cover and the cylinder
There is gasket, prevents the relief valve of the utility model for when storing product, valuable boil-off gas being caused to lose.
