Description
Technical field
The utility model relates to a kind of commercial production mechanical part, especially relates to a kind of right angle valve that is used for the fluid shunting.
Background technique
Existing valve has ball valve, stopcock etc.Valve can be divided into right angle valve and two kinds of forms of T-valve by the channel shape difference.The valve of tradition stopcock adopts traditional knob structure, import, outlet, nozzle at grade, spool is a cylinder; Tradition right angle ball valve makes spheroid rotate 90 ° through rotatable handle, can realize controlling left and right inlet with in logical communicating or closure, reach the purpose of distributing fluids.Above-mentioned valve in use for some time, the pretightening force between valve body and the seal ring is can be because of wearing and tearing, distortion etc. former thereby reduce even disappear, the structure easy abrasion, the long-term back sealing effect that uses is poor, causes liquid to reveal easily, finally makes metering deviation occur.
The model utility content
To the deficiency that exists in the above-mentioned technology; The utility model provides a kind of employing pressurized air to do power source and opens or throttle down, realizes the pneumatic right angle valve of distant control fluid open flow, and this pneumatic right angle valve seal property is good; Long service life; Compact structure, easy to maintenance, can replace pneumatic ball valve.
For realizing above-mentioned purpose, the utility model provides a kind of novel pneumatic right angle valve.
A kind of pneumatic right angle valve comprises valve body and piston, and said valve body is a L shaped right angle hollow pipeline, and its substantially horizontal one end is a water intake, and airtight cylinder is installed in the Vertical direction upper end, and the lower end is a water outlet; Piston is installed in the described cylinder, cylinder below fixed air cylinder cap, cylinder wall is provided with gas channel and feeds cylinder interior; Be equipped with in the described valve body and can alternately stop up the valve disc of closing water outlet; Described piston is connected with valve disc through valve rod, is provided with Returnning spring between piston and the cylinder.
Said cylinder bottom embeds annular retaining ring is installed, and the cylinder head fixed card is on back-up ring top, and described gas channel is between piston and cylinder head.
Described cylinder head also is provided with viewing window.
Described valve disc bottom also is provided with pad, through bolt with spacers on valve disc.
Described cylinder is connected through threaded connector with valve body.
Described cylinder and valve body joint are provided with shaft seal.
Be provided with spring between the shaft seal of described cylinder head and valve body joint.
Compared with prior art, the utlity model has following advantage:
The utility model provides a kind of pneumatic right angle valve, and airtight cylinder is installed in valve body Vertical direction upper end; Piston is installed in the cylinder, and cylinder wall is provided with gas channel and feeds cylinder interior, and pressurized air injects cylinder, drives valve disc through the promotion piston and opens and closes the entery and delivery port in the valve body; Piston is connected with valve disc through valve rod, is provided with Returnning spring between piston and the cylinder.Reciprocating type final controlling element, long service life, the unlatching life-span can reach 1,000,000 times, and is easy to maintenance, can replace pneumatic ball valve.The right-angle type valve body, in self-serviceization machinery, compact structure, installing space is little, can reduce channel bend, can control fluid automatically again.
