Description
Technical field
This utility model is related to a kind of oil valve, specifically a kind of sea cock and valve.
Background technology
Sea cock and valve is a kind of safety-valve being arranged on liquid hazardous goods pot type automotive metal constant pressure tank body loading hatch.Sea
Bottom valve is typically mounted on the tank bottom of tank truck, for from tank bottom charge of oil, during charge of oil, being pushed up by moving from driving cylinder
Valve opening lobe, sea cock and valve is opened, and oil enters into valve pocket from medium channel, then enters into storage tank from valve pocket, thus completing oil-feed
Process;Also carry out according to this principle during emptying.
Existing sea cock and valve the disadvantage is that, in use for some time, have energy loss between the piston of valve and side wall,
Cause sea cock and valve during valve closing poorly sealed, thus impact is normal using.
Utility model content
In order to make up above deficiency, this utility model provides a kind of sea cock and valve avoiding valve seal not tight, to solve
Problem in above-mentioned background technology.
The technical solution of the utility model is:
A kind of sea cock and valve, including valve casing and the valve element being arranged in valve casing, described valve casing has oil-out and oil-in,
Mounting flange on the outer wall of described valve casing, described valve element includes push rod that piston is connected with piston and is sleeved on outside push rod
Back-moving spring, also set up cylinder driver in the inner chamber of described valve casing, the output shaft of described cylinder driver is connected to
The lower end of piston, setting on the inwall of described valve casing protrudes from the annular piston limit base of inwall setting, and described limit base is cone
Shape, the lower end of described piston and limit base match setting, and the top of described piston is provided for for piston being pressed on limit base
On hold down gag, described hold down gag includes the annular recess being arranged on valve casing inwall, installs ring-type in described groove
Air bag, installs ring-type rubber closure at the slot opening outside described air bag, the upper and lower ends of described rubber closure are fixedly connected on recessed
On the side wall of groove.
As preferred technical scheme, the side wall of described valve casing is provided with the passage of plug-in mounting breather, described breather
One end is connected with air bag, and the other end of described breather is communicated in the cylinder chamber of cylinder driver, and described breather is gone here and there
Connection intake valve.
As preferred technical scheme, the lower end of described piston is the taper cartridge part matching with limit base.
Due to employing technique scheme, a kind of sea cock and valve described in the utility model passes through setting hold down gag can be made
Piston is closely sealed on valve seat, it is to avoid loosen, and after a period of time, also valve element will be caused to leak because of energy expenditure
Oil, improves the life-span using, and extends use time, improves work efficiency.
