Abstract
Sealing valve is vacuumized the invention discloses one kind, flap is provided with valve rod, flap enters the cavity of valve body by the Ka Jiao on valve body, pressure inductor, inductor connection buzzer are set on Ka Jiao；The two ends of rubber tube are connected with the inner wall sealing of valve body in cavity, there is gap between valve body and rubber tube and closed air bag is formed, vacuum (-tight) housing is set on air bag, sealing is set on valve rod and seals the second cover body for connecting with the first cover body by fastener, and leak detection mouth is set on the first cover body and the second cover body.It is simple structure of the present invention, compact, sealing area is big, the keying of valve is realized by the distending or contraction of air pressure control sebific duct, the distending amount of sebific duct is can also adjust come the flow of control valve by adjusting air pressure size, when negative pressure when vacuumizing in vacuum (-tight) housing does not reach the negative pressure of regulation always, show that the filler in valve has leakage, be easily installed maintenance, good airproof performance, long service life.
Description
Technical field
The invention belongs to valve technology field, and in particular to one kind vacuumizes sealing valve.
Background technology
Valve is widely used in industrial and agricultural production.Existing Air control valve is mainly made up of pneumatic actuator, control piper and valve etc..Its executing agency is mainly carries out rigidity keying operation by the reciprocating motion drive butterfly plate or ball valve core of cylinder or other corresponding mechanisms so that sealing position is easily damaged because of friction, and complex structure causes replacing seal more difficult.In addition, valve does not have prompting function mainly with valve body and flap combination work after traditional valve closure, the experience of individual is only relied in some cases to judge whether closure, the need for such situation cannot be met in engineering.
At present, as environmental protection concept is paid attention to extensively by people, people increasingly pay attention to the packing leaking situation of valve, the packing leaking phenomenon of valve invisible in the past, the normal of valve is not only affected to use, the leakage of the leakage of valve in-vivo medium, medium can also be caused can be caused various pollutions or human body is damaged.Meanwhile, the leakage situation of filler directly reflects whether the sealing property of valve meets the requirements, that is, people, to the sealing property requirement more and more higher of valve, the grade of sealing property its corresponding valve higher of valve is higher.However, valve of the prior art can not carry out level authentication experiment to sealing property online, i.e., existing valve is difficult to the leakage situation of on-line testing filler.
The content of the invention
Solve the problems, such as that existing operated pneumatic valve structural rigidity is opened and closed it is an object of the invention to provide a kind of operated pneumatic valve.
The technical scheme that the present invention takes is：
One kind vacuumizes sealing valve, including valve body, vacuum (-tight) housing and valve rod, and flap is provided with the valve rod, and flap enters the cavity of valve body by the Ka Jiao on valve body, and pressure inductor, inductor connection buzzer are set on Ka Jiao；Rubber tube is set in cavity, the two ends of rubber tube are connected with the inner wall sealing of valve body, there is gap between valve body and rubber tube and closed air bag is formed, vacuum (-tight) housing is set on air bag, and annular seal space is formed with air bag, vacuum (-tight) housing includes the first cover body and the second cover body, sealing contact surface is formed between the first cover body and the second cover body, sealing is set on valve rod and seals the second cover body for connecting with the first cover body by fastener, and leak detection mouth is set on the first cover body and the second cover body.
Further, fluid passage is provided with outside the rubber tube, fluid passage is arranged on valve interior wall.
Beneficial effects of the present invention are：
Simple structure of the present invention, it is compact, sealing area is big, the keying of valve is realized by the distending or contraction of air pressure control sebific duct, the distending amount of sebific duct is can also adjust come the flow of control valve by adjusting air pressure size, be enclosed in the filler of valve in it by the annular seal space formed between the first cover body and the second cover body, again by helium leak detector to being vacuumized in vacuum (-tight) housing, negative pressure until reaching regulation in vacuum (-tight) housing, when negative pressure when vacuumizing in vacuum (-tight) housing does not reach the negative pressure of regulation always, show that the filler in valve has leakage, moved up by by the second vacuum (-tight) housing, so as to be easy to open holding down assembly for filler, it is easily installed maintenance, good airproof performance, long service life, with good practical value.
Specific embodiment
One kind vacuumizes sealing valve, including valve body, vacuum (-tight) housing and valve rod, and flap is provided with the valve rod, and flap enters the cavity of valve body by the Ka Jiao on valve body, and pressure inductor, inductor connection buzzer are set on Ka Jiao；Rubber tube is set in cavity, the two ends of rubber tube are connected with the inner wall sealing of valve body, there is gap between valve body and rubber tube and closed air bag is formed, vacuum (-tight) housing is set on air bag, and annular seal space is formed with air bag, vacuum (-tight) housing includes the first cover body and the second cover body, sealing contact surface is formed between the first cover body and the second cover body, sealing is set on valve rod and seals the second cover body for connecting with the first cover body by fastener, and leak detection mouth is set on the first cover body and the second cover body.
Further, fluid passage is provided with outside the rubber tube, fluid passage is arranged on valve interior wall.
Simple structure of the present invention, it is compact, sealing area is big, the keying of valve is realized by the distending or contraction of air pressure control sebific duct, the distending amount of sebific duct is can also adjust come the flow of control valve by adjusting air pressure size, be enclosed in the filler of valve in it by the annular seal space formed between the first cover body and the second cover body, again by helium leak detector to being vacuumized in vacuum (-tight) housing, negative pressure until reaching regulation in vacuum (-tight) housing, when negative pressure when vacuumizing in vacuum (-tight) housing does not reach the negative pressure of regulation always, show that the filler in valve has leakage, moved up by by the second vacuum (-tight) housing, so as to be easy to open holding down assembly for filler, it is easily installed maintenance, good airproof performance, long service life, with good practical value.
