Abstract
The invention discloses an automatic air-pressure safety valve for tap water and relates to the air-pressure controlling automatic safety valve. The automatic air-pressure safety valve is composed of a valve body and an air-pressure cylinder and is characterized in that a water inlet and a water outlet are processed in the valve body, and a through hole is machined in the valve wall opposite to the water inlet; a support is disposed on the valve body, the air-pressure cylinder is disposed inside the support, a piston rod of the air-pressure cylinder penetrates the through hole to enter the valve, and an end cap is disposed on the front portion of the piston rod; a boss is machined in the air-pressure cylinder and is cooperatively used with a spring lock pin on the side wall of the support; the air-pressure cylinder is connected with an external air-pressure system through a pipeline; the inner wall of the valve is coated with a rustproof coating. The automatic air-pressure safety valve has the advantages of novel structure, machining easiness, convenience in use, safety and reliability and the like, and is a novel automatic air-pressure safety valve of the economical efficiency and practicability.
Description
Technical field
Air pressure tap water automatic blow off valve of the present invention, relates to a kind of air pressure control automatic safe valve.
Background technique
The situation that pipeline is revealed now occurs often, and the leakage of tap water all can bring many inconvenience to daily life and production.When leaking after generation, first thing that will do will be blocked pipeline exactly, do not allow the tap water in pipeline continue to reveal.The device that we will a leak stopping in time like this, for existing problem in above-mentioned prior art, a kind of novel air pressure tap water automatic blow off valve of research and design, is very necessary thereby overcome existing problem in prior art.
Summary of the invention
In view of existing problem in above-mentioned prior art, the object of the invention is a kind of novel air pressure tap water automatic blow off valve of research and design.In occurring to leak at pipeline, the pipeline of leakage is blocked in time, no longer made the tap water in pipeline continue to reveal.
Technical solution of the present invention is achieved in that
Air pressure tap water automatic blow off valve of the present invention, is made up of valve body and pneumatic cylinder; It is characterized in that being processed with water intake and water outlet on valve body, on the valve wall of the opposite of water intake, be processed with through hole; Support is loaded on valve body, and pneumatic cylinder is loaded in support, and the piston rod of pneumatic cylinder enters in valve body through the through hole on valve body, and in the front portion of piston rod, plug is housed; On piston rod, be processed with boss, boss is used in conjunction with the spring detent being loaded on rack side wall.Pneumatic cylinder is connected with external pressure system by pipeline; Valve interior wall scribbles rust preventive coating.
On through hole of the present invention, seal ring is housed.
Plug of the present invention is that rubber is made.
Using process of the present invention is:
In the time that external equipment receives leakage signal, start pressure system to pneumatic cylinder air feed, promote piston rod and stretch out, plug is pressed in water intake; Protracting of piston rod drives the boss on piston rod to protract, and spring detent slips over boss, and piston rod is pinned.After revealing and repairing, spring detent is opened by pressure system pressure release again to piston rod retraction Open valve.
Advantage of the present invention is apparent, is mainly manifested in:
1, the present invention can seal pipeline the very first time in the time leaking generation, can not cause larger leakage problem;
2, spring detent is equipped with in the present invention, can coordinate pressure system to carry out locking to valve, is that valve sealing is safer.
The present invention has novel structure, processes the advantages such as easy, esy to use, safe and reliable, and it puts goods on the market in enormous quantities and will produce positive social benefit and significant economic benefit.
Accompanying drawing explanation
The present invention has 1 width accompanying drawing, wherein:
Accompanying drawing 1 structural representation of the present invention.
In the drawings: 1, pipeline 2, support 3, pneumatic cylinder 4, piston rod 5, boss 6, spring detent 7, through hole 8, seal ring 9, plug 10, water outlet 11, valve body 12, water intake.
Embodiment
Specific embodiments of the invention as shown in drawings, are made up of valve body 11 and pneumatic cylinder 3; It is characterized in that being processed with water intake 12 and water outlet 10 on valve body 11, on the valve wall of the opposite of water intake 12, be processed with through hole 7; Support 2 is loaded on valve body 11, and pneumatic cylinder 3 is loaded in support 2, and the piston rod 4 of pneumatic cylinder 3 enters in valve body 11 through the through hole 7 on valve body 11, and in the front portion of piston rod 4, plug 9 is housed; On piston rod 4, be processed with boss 5, boss 5 is used in conjunction with the spring detent 6 being loaded on support 2 sidewalls.Pneumatic cylinder 3 is connected with external pressure system by pipeline 1; Valve body 11 inwalls scribble rust preventive coating.
Seal ring 8 is housed on through hole 7.
Plug 9 is made for rubber.
The above; it is only preferably embodiment of the present invention; but protection scope of the present invention is not limited to this; allly be familiar with those skilled in the art in technical scope disclosed by the invention, within being equal to and replacing or change protection scope of the present invention all should be encompassed according to technological scheme of the present invention and design of the present invention thereof.
