Abstract
The present invention relates to a kind of No leakage oil truck pneumatic tank bottom valve, including valve body, flap, piston mechanism, flap upper surface center is fixedly connected with guide rod, and the guide rod upper end and the pilot hole clearance fit of the leading truck of valve body upper end, install spring between leading truck and flap；Piston mechanism is made of piston cylinder, piston, piston rod, and piston cavity of resorption is connected by pneumatic fittings with source of the gas；Mainly piston cylinder is using the stainless steel cavity closed, it is installed on from body base fixing seal in emptying adapter passage, magnet is fixedly mounted in piston upper surface, and flap lower face is fixedly connected centrally through connecting rod with permanent magnet, and permanent magnet lower end is sleeved on the piston cylinder periphery on the outside of magnet.When air pressure promotes piston rising, the magnetic force between magnet and permanent magnet drives both one to rise, and promotion flap is opened, and is static seal structure between piston structure and valve body, realizes that medium is high without leakage, good seal performance, security performance.
Description
Technical field
The invention belongs to valve field, more particularly to a kind of pneumatic oil drain valve for being installed on oil truck tank bottom.
Background technology
Oil drain valve be installed on the conduct of oil tank car bottom will fill in oil product controlled valve, its structure generally comprise valve body, flap,
Piston mechanism, valve body are installed on tank bottom by the flange of horizontal direction, and valve body is located at flange above section insertion oil tank inner cavity,
Flange is taken over by emptying of lower part, and it is close that the internal chamber wall above and below valve body between two parts is formed with the valve seat to cooperate with flap
Front cover, flap upper surface center are fixedly connected with guide rod, the guide rod upper end and the guiding interporal lacuna of the leading truck of valve body upper end
Coordinate, spring is installed between leading truck and flap；Piston mechanism is made of piston cylinder, piston, piston rod, and piston cylinder fixes peace
In the installation cavity body of valve body emptying adapter bottom, piston rod upper end is fixedly connected with flap lower face center, outside piston rod
Dynamic sealing coordinates between disc and the hole wall for installing cavity, and piston cylinder rodless cavity is connected by pneumatic joint with pneumatic mechanism, by
Pneumatic mechanism promotes piston that flap is opened emptying.Its major defect be piston rod and install cavity hole wall between be dynamic sealing
Coordinate, in use, moving up and down for piston rod produces abrasion to the sealing ring of hole wall in installation cavity body, causes piston rod
Leakage is produced between installation cavity, in emptying, the oil medium entered from oil tank in emptying adapter will be from installation cavity leakage
To the external world, safety problem is caused.
The content of the invention
The purpose of the present invention is for shortcoming existing in the prior art, there is provided a kind of good seal performance, the nothing of safe new peak
Leak oil truck pneumatic tank bottom valve.
Technical scheme includes valve body, flap, piston mechanism, and valve body is installed on oil tank by the flange of horizontal direction
Bottom, valve body are located at flange above section insertion oil tank inner cavity, and flange is taken over by emptying of lower part, two parts above and below valve body
Between internal chamber wall be formed with the sealing surface of seat to cooperate with flap, flap upper surface center is fixedly connected with guide rod, this is led
To bar upper end and the pilot hole clearance fit of the leading truck of valve body upper end, spring is installed between leading truck and flap；Piston machine
Structure is made of piston cylinder, piston, piston rod, and piston cavity of resorption is connected by pneumatic fittings with source of the gas；Mainly piston cylinder is using envelope
The stainless steel cavity closed, is installed in emptying adapter passage from body base fixing seal, and magnet is fixedly mounted in piston upper surface,
Flap lower face is fixedly connected centrally through connecting rod with permanent magnet, and the piston cylinder that permanent magnet lower end is sleeved on the outside of magnet is cylindrical
Face.
Preferably, guide plate centre bore clearance fit of the piston rod upper end with being fixedly mounted on piston cylinder inner cavity.
It is an advantage of the invention that being installed on body base using the piston cylinder fixing seal of enclosed construction, air pressure promotes piston
During rising, the magnetic force between magnet and permanent magnet drives both one to rise, and promotes flap to open, between piston structure and valve body
For static seal structure, realize that medium is high without leakage, good seal performance, security performance.
Brief description of the drawings
Fig. 1 is the structure diagram of the present invention.
Embodiment
No leakage oil truck pneumatic tank bottom valve as shown in Figure 1, including valve body 4, flap 6, piston mechanism, valve body 4 is by water
Square to flange be installed on tank bottom, valve body 4 is located at flange above section insertion oil tank inner cavity, and flange is using lower part to unload
Oil adapter, the valve base sealing to cooperate with the sealing ring 7 on flap 6 is formed with internal chamber wall of the valve body about 4 between two parts
Face, 6 upper surface center of flap are fixedly connected with guide rod 1, between the pilot hole of the leading truck 2 of 4 upper end of 1 upper end of guide rod and valve body
Gap coordinates, and spring 3 is installed between leading truck 2 and flap 6, and filter screen 5 is set in the oil entered window of valve body 4；Piston mechanism by
Piston cylinder 11, piston 9, piston rod 14 form, and 9 cavity of resorption of piston is connected by pneumatic fittings 10 with source of the gas；Piston cylinder 11 is using envelope
The stainless steel cavity closed, which is installed in its emptying adapter passage from 4 bottom fixing seal of valve body, on piston 9
Magnet 13 is fixedly mounted in end face, and 6 lower face of flap is fixedly connected centrally through connecting rod with permanent magnet 8,8 lower end of permanent magnet suit
11 periphery of piston cylinder in the outside of magnet 13.When air pressure promotes piston 9 to rise, magnet 13 produces permanent magnet 8 upward
Thrust is more than the elastic force of spring 3, ensures to drive 8 synchronizing moving of permanent magnet when magnet 13 moves up.
The centre bore clearance fit of guide plate 15 of 14 upper end of piston rod with being fixedly mounted on 11 inner cavity of piston cylinder.Positioned at
11 inner cavity of piston cylinder of the top of guide plate 15 is equipped with the return-air hole of connection ambient atmosphere.Between 9 lower face of piston and piston cylinder 11
Equipped with position sensor 12, the on off state of valve is monitored.
