Abstract
Disclosed is a pipe air one-way valve, which comprises a valve base 1, a bonnet 2, an annular flexible sheet 4 and a piston ring 3. Said valve base 1 has a concentric inner ring housing 5 and an outer ring housing 6, they are connected by a wing panel to form an external intake duct, the annular flexible sheet 4 and the piston ring 3 is mounted on inner surface of the outer ring housing 6, and outer edge of the annular flexible sheet 4 is clamped by the outer ring housing 6 and the piston ring 3, while the inner edge is closely integrated with the valve base 1. The product is mainly used in drainage system, also can be used in other low pressure gas-liquid pipelines, and air can be supplied without the pipeline extension out of the building, as a result, the end water seal is protected.
Description
Technical field: the present invention relates to a kind of construction drainage pipeline air check valve.
Background technology: architectural drainage system adopts the inside and outside air of sealing structure for water isolating pipelines to exchange usually; but flowing, the drainage procedure of pipeline or air all can cause pipe negative pressure; negative pressure surpasses the water seal that certain numerical value will be destroyed terminal or water appliance; cause pipeline gas to leak; excessive for preventing pipe negative pressure; effectively protection water seal, traditional architectural drainage system all are provided with the stack vent of straight-through atmosphere or lay assisted ventilation standpipe arranged side by side specially is that soil stack replenishes air.But modern architecture adopts pitched roof or roof garden usually, and the roof is provided with to be stretched the push pipe road in a large number and not only influence architectural appearance, increases the roof waterproof construction difficulty, does not also satisfy the function of use on roof.
Summary of the invention:
The objective of the invention is to: provide a kind of and needn't stretch the top, the pipeline air check valve of structure uniqueness, when pipeline can replenish air during for negative pressure in pipe, when pipeline was equipressure or malleation, the interior smell of pipe capable of blocking escaped.
The object of the present invention is achieved like this:
The pipeline air check valve, its composition comprises: valve seat, bonnet, annular resilient diaphragm and piston ring, described annular resilient diaphragm and piston ring are installed on the internal face of valve seat outer ring housing, the outer rim of described annular resilient diaphragm is clamped by valve seat outer ring housing and piston ring, fit in the ring packing plane of inner edge and valve seat, described bonnet is enclosed within on the outer cylinder of outer ring housing.
Above-mentioned pipeline air check valve, described inner ring housing is positioned at the bottom of valve seat, and the inner ring housing has surrounded the center airway, and is connected with system pipeline.
Above-mentioned pipeline air check valve, the outer ring housing of described valve seat is positioned at the top of valve seat, connects and composes the outer shroud air intake duct with fin between the Internal and external cycle housing.
Above-mentioned pipeline air check valve has a sealing anchor ring in the middle of the described valve seat inner ring housing.
Above-mentioned pipeline air check valve, the top of making the time spent valve in no external force is sealed gas chamber.
The invention has the advantages that:
1. pipeline air check valve, the outer rim of its annular resilient diaphragm is clamped fixing, has only inner edge to be used for sealing or opens, and that this structure has is simple in structure, open characteristics such as pressure reduction is little, dynamic characteristic sensitivity.
2. this product replaces stack vent traditional in the construction drainage pipeline and assisted ventilation pipe side by side, does not stretch out at pipeline under the situation of roofing and realizes the pipeline tonifying Qi, prevents to produce negative pressure in the pipeline, has protected the duct end water seal.
3. the one-sided anchor ring of the rubber diaphragm of this product is fixedly clamped, and one-sided opening encapsulation has only an annular sealing surface compared with similar products.
4. the circular passage gas inlet hole sectional area of this product is big, the efficient height, and tonifying Qi is effective.
Description of drawings: accompanying drawing 1 is the structural representation of this product.
Accompanying drawing 2 is isobaric and positive seal schematic diagrams in the pipeline.
Accompanying drawing 3 is negative pressure tonifying Qi schematic diagrams in the pipeline.
Below in conjunction with the concrete embodiment of description of drawings:
The pipeline air check valve, its composition comprises: valve seat 1, bonnet 2, annular resilient diaphragm 4 and piston ring 3, described annular resilient diaphragm 4 and piston ring 3 are installed on the internal face of valve seat outer ring housing 6, the outer rim of described annular resilient diaphragm 4 is clamped by outer ring housing 6 and piston ring 3, fit in the ring packing plane of inner edge and valve seat 1, described bonnet 2 is enclosed within on the outer cylinder of outer ring housing 6.
Above-mentioned pipeline air check valve, described inner ring housing 5 is positioned at the bottom of valve seat 1, and inner ring housing 5 has surrounded center airway 8, and is connected with system pipeline.
Above-mentioned pipeline air check valve, the outer ring housing 6 of described valve seat 1 is positioned at the top of valve seat, and linking to each other with fin between the Internal and external cycle housing constitutes outer shroud air intake duct 7.
Above-mentioned pipeline air check valve, after described bonnet 2 and annular resilient diaphragm 4 installed, the top of valve was sealed gas chamber 9 under no external force active state.
Above-mentioned pipeline air check valve has a sealing anchor ring 10 in the middle of the described valve seat 1 inner ring housing 5.
Above-mentioned pipeline air check valve, when pipeline pressure is equal to or higher than ambient pressure (pipeline equipressure or malleation), annular resilient diaphragm 4 is adjacent to the ring packing plane of valve seat 1 by self elastic force, tight sealing outer shroud air intake duct 7, stop in the smell effusion pipeline inlet chamber in the drainage system, when pipeline pressure was lower than ambient pressure (pipe negative pressure), described annular resilient diaphragm 4 was subjected to the promotion of external air pressure to float suck air automatically.
Claims (5)
1. pipeline air check valve, its composition comprises: valve seat, bonnet, annular resilient diaphragm and piston ring, it is characterized in that: described annular resilient diaphragm and piston ring are installed on the inner cylinder of valve seat outer ring housing, the outer rim of described annular resilient diaphragm is clamped by valve seat outer ring housing and piston ring, fit in the ring packing plane of inner edge and valve seat, described bonnet is enclosed within on the outer cylinder of outer ring housing.
2. pipeline air check valve according to claim 1 is characterized in that: described inner ring housing is positioned at the bottom of valve seat, and the inner ring housing has surrounded the center airway, is connected with system pipeline.
