Description

A kind of self-acting valve

Technical field

The utility model relates to a kind of pipeline fluid control gear, relates in particular to a kind of self-acting valve.

Background technique

In the utility pipes technology industry, arrive when winter, after using the line transportation fluid in the productive life, can in pipeline, leave ponding, through an All Through The Night, ponding in the pipeline can be owing to cold weather freezes, and with frost crack pipe, how solving the automatic earial drainage of pipeline is a great problem of water supply line technology in winter all the time.

Existing solution is: 1, manually the ponding in the pipeline is got rid of, but discharging as not thorough, had the ponding still can the bursting by freezing pipeline in the pipeline part; 2, outside pipeline, add adiabator layer or heating equipment, this solution cost height, and dangerous.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of self-acting valve, and it is simple in structure, and is with low cost, can realize automatically with ponding discharging in the pipeline, thoroughly solve pipeline bursting by freezing in winter problem, also need not pipeline is set up adiabator layer, saved user cost.

For solving the problems of the technologies described above, the utility model adopts following technical proposals: a kind of self-acting valve, and it comprises valve body; Described valve body comprises that the end is provided with the tubular housing of screw mouth, built-in upper valve base, lower valve base and the sliding fit that is fixed in the tubular housing is socketed on the sliding stem on the lower valve base, and described upper valve base and lower valve base are separated into water chamber, sluicing chamber and water-inlet cavity three parts with tubular housing; Offer spilled water hole on the described body wall; Described upper valve base is Cylindrical object, this Cylindrical object offers at least two water outlet through holes vertically, and this Cylindrical object middle part is provided with the right angle type passage vertically, this right angle type passage feed-water end is opened in the Cylindrical object lower surface, and the waterexit end is opened in Cylindrical object sidewall and corresponding with the spilled water hole coupling of body wall; Described lower valve base is Cylindrical object, and this Cylindrical object evenly offers at least two water outlet through holes vertically, so that current evenly spray to sliding bar, with sliding bar jack-up, and the lower valve base middle part offers the valve stem slides passage vertically; Described sliding stem is made of spilled water hole locking device, slider disc and guide rod, and described guide rod passes slider disc fixedlys connected with the spilled water hole locking device, and this guide rod sliding fit is sheathed in the valve stem slides passage at lower valve base middle part.

Described spilled water hole locking device is cylindric sealing gasket or spheroid, the diameter of this cylindric sealing gasket or spheroid is greater than the diameter of upper valve base lower surface middle part right angle type passage feed-water end, so that valve rod can seal right angle type passage feed-water end when rising, make the water outlet through hole of current direction upper valve base.

The diameter of described slider disc is the circumscribed diameter in the center of circle with the lower valve base center greater than lower valve base upper water-out through hole, so that when cutting off current, after the valve rod gravitate falls after rise, cover the water inlet through hole on the lower valve base, ponding in the water chamber of upper valve base top passes back into the sluicing chamber, can only discharge from the spilled water hole of valve body.

Tubular body is equipped with at the spilled water hole place of described valve body outer side wall, and this tubular body outer side wall is provided with outside thread, so that screw togather external drainage pipe.

The internal surface place of the tubular housing upper and lower end parts of described valve body is provided with internal thread.

The outer surface of the tubular housing upper and lower end parts of described valve body is provided with outside thread.

The internal surface and the outer surface of the tubular housing upper and lower end parts of described valve body are respectively equipped with internal thread and outside thread.

Because above-mentioned a kind of self-acting valve only is applicable to vertically and is connected with water supply line, so, a spring housing is connected to outside the guide rod of sliding stem, and the two ends of spring are fixedly arranged on the lower end of the guide rod face place of the lower surface and the sliding stem of lower valve base respectively, make valve rod can do the elasticity to-and-fro motion, avoided the current in the water-inlet cavity too small, the aqueous reflux in a part of water chamber is back in the water cavity, but also makes a kind of self-acting valve level be connected on the water supply line.

The utility model is simple in structure, and is with low cost, can realize automatically ponding in the pipeline being discharged, and thoroughly solves pipeline bursting by freezing in winter problem, also need not pipeline is set up adiabator layer, saved user cost.
