Abstract
The utility model discloses an exhaust pipe for a quick exhaust valve. The exhaust pipe comprises a step-shaped pipe body. The outer wall of the pipe body upper end is provided with an outer screw thread. A convex ring is provided on the inner wall of the pipe body lower end. A spring is placed on the convex ring. The upper end of the pipe body is screwed with an adjusting nut. The exhaust pipe provided by the utility model has a simple structure, and has convenience in installation and use. A floating ball is made to move along a guide column. Thus, irregular movement of the floating ball is avoided. The working efficiency of the exhaust valve is affected by the irregular movement of the floating ball. The exhaust pipe is suitable for a water transmission pipe, the service life is long and the exhaust pipe is safe and reliable.
Description
Technical field
The utility model relates generally to a kind of row of conduits device of air, relates in particular to a kind of rapid escape valve and uses outlet pipe.
Background technique
Outlet valve is applied to pipeline exhausts such as independent heating system, central heating system, heating boiler, central air-conditioner, floor heating and solar heating system.Because all be dissolved with certain air in the water usually; And the solubility of air reduces along with the rising of temperature, and water gas in the circuit process is separated from water gradually like this, and gets together gradually and form big bubble even gas column; Because replenishing of water arranged, so often there is gas to produce.Because the generation of gas, pipeline can occur water interruption, power failure, termination of pumping pipeline in the running and occur in time that negative pressure can cause pipe vibration or phenomenon such as break.Present existing outlet valve; All be the structure that adopts valve body, valve gap, ball float etc. to form, ball float is positioned at valve body, no matter is air inlet or exhaust; Ball float all is in valve body, to do random motion; Thereby reduced the working efficiency of outlet valve, thereby influenced the proper functioning of outlet valve, caused pipe vibration or break.
The model utility content
The purpose of the utility model is in order to remedy the deficiency of prior art; Provide a kind of rapid escape valve to use outlet pipe, the random motion that has solved ball float reduces the working efficiency of outlet valve, and the outer foreign material of valve body get into the problems such as motion that can influence ball float in the valve body; Long service life, safe and reliable.
The utility model is realized through following technological scheme:
A kind of rapid escape valve is used outlet pipe, includes step-like body, and the upper end outer wall of body has outside thread, and the lower end inwall of body is provided with protruding circle, is placing spring on the protruding circle.
Described body upper end has screwed togather adjusting nut.
The working principle of the utility model is: during exhaust condition, ball float makes the air outlet space occur owing to transport to its bottom with action of gravity along tubular ball float carriage downstream, and air is just discharged by exhaust port through this space; When air had been arranged, water got in the valve body, and ball float can rise along guide pillar along with buoyancy of water; Just in time block the air outlet, stop exhaust, prevent power failure, termination of pumping; Phenomenons such as negative pressure appear in in-pipe flow at any time when empty, and in the pipe in case when negative pressure occurring, this valve can suck air rapidly; Produced damage with the keeping road because of negative pressure, guaranteed pipe safety.
The utility model has the advantages that:
The utility model is simple in structure, easy to install, and ball float is moved along guide pillar, has avoided random motion, hinders the motion of ball float, has influenced the working efficiency of outlet valve, be applicable in the pipeline of water delivery, and long service life, safe and reliable.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Referring to accompanying drawing, a kind of rapid escape valve is used outlet pipe, includes step-like body 1, and the upper end outer wall of body 1 has outside thread 2, and the lower end inwall of body 1 is provided with protruding circle 3, is placing spring 4 on the protruding circle 3, and body 1 upper end has screwed togather adjusting nut 5.
Claims (2)
1. a rapid escape valve is used outlet pipe, includes step-like body, it is characterized in that: the upper end outer wall of body has outside thread, and the lower end inwall of body is provided with protruding circle, is placing spring on the protruding circle.
