Abstract
The utility model discloses an automatic air sucking valve for pipelines. An annular groove is arranged on a movable valve, and a sealing ring is tightly inserted into the annular groove to change a traditional water discharging method; the utility model also solves the disadvantage that at present, similar products can not be sealed tightly. The utility model can be used for water supplying and discharging pipeline systems of multilayer buildings, tall buildings, high-grade residential districts and families.
Description
Technical field
The utility model relates to the parts in a kind of building water supply and drainage pipe-line system, relates to the automatic inlet valve of a kind of pipeline that is installed on the drainage pipe particularly.
Background technology
In preceding existing building water supply and drainage pipe-line system, in order to make intrasystem current unobstructed, and make intrasystem pressure and atmospheric pressure balance, protect the water seal of each parts, the assisted ventilation pipeline just must be installed or inlet valve be installed in the terminal of pipeline.Along with construction work develops to multiple stratification, high stratification, house fitting-up to become more meticulous, superior development, to improving constantly of the performance requirement of inlet valve, particularly flexibility, sealing, the reliability to inlet valve proposed higher requirement, and existing inlet valve can't satisfy, even has because the report that the inlet valve fault causes the associated pipe system to work.
The utility model content
The purpose of this utility model is that the above-mentioned technological deficiency at existing inlet valve exists provides a kind of automatic inlet valve with good seal, flexible movements, reliable operation.
The technical scheme that the utility model provides is as follows: the automatic inlet valve of a kind of pipeline, comprise valve body 1, valve gap 2, moving valve 3, sealing ring 4, valve gap 2 is socketed on the valve body 1, moving valve 3 is arranged on valve body 1 and is connected with valve gap 2 in the back cavity that forms, sealing ring 4 is arranged between moving valve 3 and the valve body 1, it is characterized in that: the stage casing of described moving valve 3 be provided with one with the suitable cannelure 5 of described sealing ring 4 endoporus, described sealing ring 4 inserts in this cannelure 5, connects together with moving valve 3.
Described valve body 1, valve gap 2, moving valve 3, sealing ring 4 are independent separately plastic cement members that assemble.
Described valve gap 2 is suitable bowl-shape of internal diameter and valve body 1 external diameter, and its middle part also is provided with valve shaft 6.
Described moving valve 3, the middle part is provided with through hole, is enclosed within on the valve shaft 6, and can be up and down along valve shaft 6 in cavity.
Described sealing ring 4 is the flexible plastic cement members of a ring-type; Its middle part be provided with endoporus, be socketed on the moving valve 3, and can with moving valve 3 in cavity along valve shaft about in the of 6 activity and activity.
Described valve body 1 is the tubulose that a diameter and wall thickness do not wait, and its vertical section is the halfpace shape; Also be provided with air inlet 7 and drain hole 8 on the valve body 1.
The utility model advantage is: because moving valve is provided with cannelure, and closely inserts joint ring in this cannelure, make sealing tight reliable; Owing to adopted smooth center rail, made to open and close flexibly; Owing to adopted gravitational difference pressure type operating principle, only air-breathing not exhaust prevents that gas rushes down in the pipeline outward; And it is low to open head (negative pressure value), and the tonifying Qi sensitivity possesses big capacity gettering ability and draining phantom load ability, quiet noiseless action, automatic, noiselessness; Can extensively be fit to and multilayer and highrise building, and the water-feeding ﹠ drainaging pipeline system of high-grade house fitting-up engineering.

The specific embodiment
Below in conjunction with embodiment, the utility model is further specified.
Embodiment: as Fig. 1-5, the automatic inlet valve of a kind of pipeline, the valve body 1, valve gap 2, moving valve 3 and the rubber seal 4 that comprise plastic material, valve gap 2 is socketed on the valve body 1, moving valve 3 is arranged on valve body 1 and is connected with valve gap 2 in the back cavity that forms, sealing ring 4 is arranged between moving valve 3 and the valve body 1, it is characterized in that: the stage casing of described moving valve 3 be provided with one with the suitable cannelure 5 of described sealing ring 4 endoporus, described sealing ring 4 inserts in this cannelure 5, connects together with moving valve 3.
Described valve body 1, valve gap 2, moving valve 3, sealing ring 4 are independent separately plastic cement members that assemble, and are convenient to processing and assembling.Described valve gap 2 is suitable bowl-shape of internal diameter and valve body 1 external diameter, and its middle part also is provided with valve shaft 6.The surface of valve shaft 6 is more smooth.
Described moving valve 3, the middle part is provided with through hole, is enclosed within on the valve shaft 6, and can be up and down along valve shaft 6 in cavity.
Described sealing ring 4 is the flexible plastic cement members of a ring-type; Its middle part be provided with endoporus, be socketed on the moving valve 3, and can with moving valve 3 in cavity along valve shaft about in the of 6 activity and activity.
Described valve body 1 is the tubulose that a diameter and wall thickness do not wait, and its vertical section is the halfpace shape; Also be provided with air inlet 7 and drain hole 8 on the valve body 1.
Operating principle of the present utility model is such: when the increase of pipe-line system internal gas pressure, during greater than system's external pressure, air pressure makes sealing ring 4 tightly touch valve body 1, and the air inlet 7 on the valve body 1 is shut; And the pressure in pipe-line system reduces, and during less than external pressure, air pressure inwardly promotes sealing ring 4 along valve shaft 6, and the air inlet 7 on the valve body 1 is opened, and air enters, thereby makes system's internal gas pressure and external pressure keep balance; Condensed water in the pipeline is derived from drain hole 8.
