Abstract

The utility model discloses a novel automatic pipeline exhaust valve, which is mainly used for the air exhaust of heating equipment. The utility model comprises a valve body 1, a ball float 10 is arranged in the valve body 1, and an air vent 5 is arranged at the upper part of the valve body 1. The utility model is characterized in that a valve plug sleeve 13 is arranged in the ball float 10, a valve plug 2 is arranged in the valve plug sleeve 13, a rubber cushion 3 is arranged at the upper end of the valve plug 2 and is matched with the air vent 5, the lower end of the valve plug 2 is matched with the ball float 10, and a channel 14 is arranged between the cavity of the valve body 1 and the air vent 5. The utility model has the advantages that the movement is flexible and reliable, and the service life is long. The structure breaks up the complex design routines that the internal structure of the former valve depends on a metal spring to reset and a lever to increase the force, etc., the buoyancy of the ball float of the valve in the water is utilized to interact directly with the heavy-weighted hammer effect of the deadweight of the valve plug, to attain the purpose of air-water separation. The designed structure is simple, the performance is stable, the novel automatic pipeline exhaust valve is sensitive, durable, secure, and reliable, the service is convenient, the volume is small, the shape is artistic, the manufacture cost is low, and thus the utility model is economical and applicable.

Description

The novel pipeline automatic control pressure vent

Technical field:

The utility model relates to a kind of venting gas appliance, particularly a kind of novel pipeline automatic control pressure vent.Be mainly used in the exhaust of heating equipment.

Background technique:

The concentrated supply of heating in the city in winter is the important component part that the northern China urban function is built.The quality of Winter heat supply quality directly influences the people's daily life, and is closely related with the people's interests.All departments attach great importance to this.According to heating experience for many years, to the water-heating boiler pipe network system, cause the heat supply actual effect not good because of exhaust is bad, and problem such as caused various heat supply accidents is of common occurrence.In the heating network system of complexity, because of the gas that various factors produced, because the automatic control pressure vent performance failure in the pipe network system, the gas that is detained in the pipe network system can not be discharged, be to cause the pipe network system circulation bad, user's radiator part is not hot, even abrupt pressure increases the one of the main reasons of pipeline, heating installation explosion.Therefore, the automatic exhaust valve of safe and reliable, stable performance, economy and durability to boiler pipe network security of system, improves heating quality, and particularly economic benefit and the social benefit to heating enterprise is significant, and its effect is very important.The various automatic exhaust valves that use do not reach stable functional effect in actual use at present.Its structure is that a valve body is arranged, and a ball float is arranged in the valve body, and ball float connects lever and spring, and ball float just moves up and down with liquid level, drives lever, spring action, seals and open exhaust port by the sealing gasket in it again.Its internal structure complexity, after long-time the use, lever action is dumb, easily loses usability, and the life-span is short, increases maintenance frequency and engineering time, has increased operating cost simultaneously.

Summary of the invention:

The purpose of this utility model provides that a kind of flexible movements are reliable, the novel pipeline automatic control pressure vent of long service life.To overcome the deficiencies in the prior art.

Technical solution of the present utility model is: a kind of novel pipeline automatic control pressure vent, it comprises valve body 1, be provided with ball float 10 in the valve body 1, the top of valve body 1 is provided with exhaust port 5, it is characterized in that: be provided with valve plug cover 13 in ball float 10, be provided with valve plug 2 in the valve plug cover 13, the upper end of valve plug 2 is provided with rubber cushion 3 and matches with exhaust port 5, the lower end of valve plug 2 and ball float 10 match, and between the inner chamber of valve body 1 and the exhaust port 5 passage 14 are arranged.

Described passage 14 is located at valve plug and overlaps on 13 madial walls.

The utility model has compared with prior art that flexible movements are reliable, the advantage of long service life.This structure has been broken in the past that the valve internal structure resets by metal spring and has lever augmentedly been waited complicated design routine, with the weight effect direct interaction that the buoyancy of valve ball float in water and valve plug are conducted oneself with dignity, reaches the purpose of air-water separation.Project organization is simple, stable performance, sensitive and durable, safe and reliable, easy to maintenance, volume is little, handsome in appearance, the cost cost is low, economic and practical.

Description of drawings:

Fig. 1 is the utility model overall structure schematic representation;

Fig. 2 is an A-A generalized section shown in Figure 1.

Embodiment: as shown in the figure: 1 is valve body, adopts brass material to make, and through lost wax casting technology, precision machining is made, and reaches aesthetic in appearance, resists actual effects such as rotten, withstand voltage.Valve body 1 top scyewed joint has valve gap 8, establishes sealing gasket 9 between valve gap 8 and the valve body 1.Scyewed joint has spool tegillum 6 on the valve gap 8, and spool tegillum 6 tops are connected to external tapping 4, are provided with exhaust port 5 in it, and the below of spool tegillum 6 is connected to valve plug cover 13, and described spool tegillum 6, external tapping 4, valve plug cover 13 are structure as a whole.The upper end of the valve plug 2 in the valve plug cover 13 is inlaid with rubber cushion 3, and rubber cushion 3 is positioned at the below of exhaust port 5.The material of valve plug cover 13, valve plug 2 is a brass.Ball float 10 is positioned at the below of the top valve plug 2 of 1 time water guide gas port 11 of valve body.Ball float 10 is made by high temperature resistant, aging-resistant synthetic plastic blow moulding and forming or with the sheet copper punching press.The diameter of exhaust port 5 is 3 millimeters, and more existing valve is big, to reduce the impact of pipe-line system internal pressure to the outlet valve exhaust process, prolong valve working life, particularly be embedded in the working life of valve plug 2 top rubber cushions, reaching simultaneously has gas to discharge fast, the purpose of the noise when reducing exhaust.

As shown in Figure 2: vertically be provided with four and be criss-cross passage 14 on the madial wall of valve plug cover 2, passage 14 is communicated with the inner chamber of valve body 1 with exhaust port 5.

Working procedure is: with pipeline connection port 12 this device is fixed in the system, when in the system gas being arranged, can discharges through inner chamber, passage 14, the exhaust port 5 of valve body 1 automatically, after draining, liquid level rises ball float 10 is floated, and moves on the jack-up valve plug 2, and this moment, rubber cushion 3 was sealed exhaust port 5 sealings.
