Abstract
The utility model relates to an automatic exhaust device for a heating pipeline. The automatic exhaust device comprises a central heating pipeline exhaust channel and an exhaust valve, wherein the exhaust valve is connected with the central heating pipeline exhaust channel through a thread; and the automatic exhaust device is characterized in that the exhaust valve comprises a valve body; a ball seat step is formed on the lower part in the valve body; an exhaust valve ball, a spring and a spring pressing cap are sequentially arranged above the exhaust valve ball from bottom to top; the spring pressing cap is connected to the middle of the valve body through a thread; the upper end of the exhaust valve is in threaded connection with a variable thread joint; the upper end of the variable thread joint is in threaded connection with an exhaust pipe joint; and an exhaust pipe is in threaded connection with the exhaust pipe joint. The automatic exhaust device has the advantages that the associated gas generated in a heating working medium can be timely discharged out of the heating pipeline through the automatic exhaust device in the running period of the heating pipeline, and the problems that the liquid level in the heating pipeline is extremely low due to extremely high gas pressure and the gas blocks the operation of the working medium in the pipeline are solved, so that the smooth operation of the heating pipeline is guaranteed.
Description
Technical field
The utility model belongs to the automatic control pressure vent field, particularly relates to a kind of heating pipeline.
Background technique
At present, in the civil heating field, often need on heating installation the manual exhaust device is installed, be commonly called as " race wind ", in order to discharge the gas in heating installation, to guarantee the proper flow of hot water.But for the gas in pipeline, because the mounting point of some pipeline is special, if use the manual exhaust device, staff or attendant or user are difficult to often access.So when gas occurring in pipeline, gas is difficult to timely discharge, thereby cause hot water to flow, affected heating effect.
Summary of the invention
The utility model provides a kind of simple in structure, convenient operation and safe and reliable heating pipeline automatic exhaust device for solving the technical problem that exists in known technology.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of heating pipeline automatic exhaust device is characterized in that: comprise heating pipeline exhaust passage and outlet valve, outlet valve is connected with heating pipeline exhaust passage by screw thread; Described outlet valve comprises valve body, in valve body, the bottom is provided with the ball seat step, be equipped with successively from bottom to top exhaust valve ball, spring and spring pressure cap on the ball seat step, spring pressure cap silk is connected on valve body middle part by linking, the outlet valve upper end has been threaded connection the change inipple, change inipple upper end has been threaded connection exhaust fitting, has been threaded connection outlet pipe in exhaust fitting.
The utility model can also be by the following technical solutions:
Described spring pressure cap has diameter greater than the flange part of the major diameter of thread that is threaded with it.
Advantage and the good effect that the utlity model has are:
After the utility model has adopted above technological scheme, during having guaranteed the heating pipeline run duration, the associated gas that produces in heating working medium can be discharged the heating pipeline by automatic exhaust device timely, avoid because the excessive liquid level that causes in the heating pipeline of gas pressure is too low, the problem of the working medium operation in the clogging pipeline of gas, thereby the smooth and easy operation of assurance heating pipeline.
Description of drawings
Fig. 1 is structural representation of the present utility model.
In figure: 1, heating pipeline exhaust passage; 2, outlet valve; 2-1, ball seat step; 2-2, exhaust valve ball; 2-3, spring; 2-4, spring pressure cap; 2-5, valve body; 3, become inipple; 4, exhaust fitting; 5, outlet pipe.
Embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
See also Fig. 1, a kind of heating pipeline automatic exhaust device is characterized in that: comprise heating pipeline exhaust passage 1 and outlet valve 2, outlet valve 2 is connected with heating pipeline exhaust passage 1 by screw thread; Described outlet valve 1 comprises valve body 2-5, in valve body 2-5, the bottom is provided with ball seat step 2-1, be equipped with successively from bottom to top exhaust valve ball 2-2, spring 2-3 and spring pressure cap 2-4 on ball seat step 2-1, spring pressure cap 2-4 is threaded connection at valve body 2-5 middle part, outlet valve 2 upper ends have been threaded connection and have become inipple 3, change inipple 3 upper ends have been threaded connection exhaust fitting 4, have been threaded connection outlet pipe 5 in exhaust fitting 4
The spring pressure cap has diameter greater than the flange part of the major diameter of thread that is threaded with it, be screwed into the degree of depth in order to limit the spring pressure cap by a flange part in screw thread, excessively dark with what avoid the spring pressure cap to be screwed into, cause the spring upward pressure excessive, too much gas can't be discharged, and causes heating effect to descend.
Operating principle of the present utility model is:
before use outlet valve is connected according to diagram, in heating pipeline running, when producing associated gas in the heating pipeline, gas group assembles in the top of heating pipeline eminence, accumulation along with the production time, associated gas is more and more, can be up along heating pipeline exhaust passage 1 with the micro gas-bubble of certain pressure, and then micro gas-bubble passes microgap between exhaust valve ball 2-2 and venting ball seat stand rank 2-1 under surface tension effects, gas enters exhaust valve ball 2-2 upper space, then by valve body 2-5, become inipple 3, along outlet pipe 5 until exhaust outlet, thereby reach the purpose of exhaust.Under exhaust valve ball 2-2 deadweight and the effect of spring 2-3 reposition force, exhaust valve ball 2-2 and ball seat are realized the sealing to top highly pressurised liquid (hydrops).
Claims (2)
1. a heating pipeline automatic exhaust device, comprise heating pipeline exhaust passage and outlet valve, and outlet valve is connected with heating pipeline exhaust passage by screw thread, it is characterized in that:
Described outlet valve comprises valve body, in valve body, the bottom is provided with the ball seat step, the top of ball seat step is equipped with exhaust valve ball, spring and spring pressure cap from bottom to top successively, wherein, the spring pressure cap is threaded connection at the valve body middle part, the outlet valve upper end has been threaded connection the change inipple, becomes the inipple upper end and has been threaded connection exhaust fitting, has been threaded connection outlet pipe in exhaust fitting.
2. heating pipeline automatic exhaust device according to claim 1, it is characterized in that: described spring pressure cap has diameter greater than the flange part of the major diameter of thread that is threaded with it.
