Abstract
The utility model discloses an automatic control combined type exhaust valve, which is characterized in that a bracket body is arranged inside a main cylinder body, a sealing ring with a rubber sealing base is arranged on the bracket body, the sealing ring is connected with a guide base, a floating body with a guide rod is arranged in the bracket body, a set of micro-exhaust components is arranged in an auxiliary cylinder body, a fixing cover plate is arranged on a valve body, and a valve cap is arranged on the upper portion of the fixing cover plate. The automatic control combined type exhaust valve is adaptable to outlets of pumps and hydraulic pipelines, and is used to discharge large quantities of accumulated air in the pipelines to increase benefit of water conveying devices and protect the pipelines from deforming and breaking. Compared with the prior art, the utility model has outstanding substantive characteristics and marked improvement.
Description
Technical field:
The utility model relates to the technical field of valve, a kind of specifically automatic control composite exhaust valve, particularly its mechanical connecting structure.
Background technique:
Existing outlet valve is a unitary, when assembling air in a large number in the pipeline, and a large amount of quick drain of energy, but for minimum gas, its effect is not remarkable, and practicability is relatively poor.
So still need existing exhaust structure is further improved.
Summary of the invention:
The purpose of this utility model is to provide a kind of automatic control composite exhaust valve, is used for getting rid of a large amount of air of assembling of pipeline, and benefit and the unlikely deformation fracture of protection pipeline to improve transporting water equipment have overcome the shortcoming and defect that exists in the prior art.
To achieve these goals, technological scheme of the present invention is: a kind of automatic control composite exhaust valve, it mainly comprises valve body, and body cavity is integral by Master cylinder body and subsidiary cylinder connection, it is characterized in that: be provided with one in the described Master cylinder body and take off support body, take off the seal ring that the support body place is provided with band rubber seal seat, seal ring connects guide holder, takes off to be provided with a guide buoyancy aid in the support body, is provided with the micro-discharge means of a cover in the subsidiary cylinder, the valve body place is provided with securing cover plate, and securing cover plate top is provided with bonnet.
The utility model discloses a kind of automatic control composite exhaust valve; it is applicable in delivery side of pump place and the water transport pipeline; be used for getting rid of a large amount of air of assembling of pipeline; benefit and the unlikely deformation fracture of protection pipeline to improve transporting water equipment have outstanding substantive distinguishing features and remarkable progress compared to existing technologies.
Description of drawings:
Fig. 1 is the utility model structural representation
Embodiment:
With reference to the accompanying drawings, the utility model further is described
The utility model is a kind of automatic control composite exhaust valve, it mainly comprises valve body 1, valve body 1 inner chamber is integral by Master cylinder body 16 and subsidiary cylinder 17 connections, it is characterized in that: be provided with one in the described Master cylinder body 16 and take off support body 4, take off the seal ring 5 that support body 4 places are provided with band rubber seal seat 7, seal ring 5 connects guide holder 6, take off and be provided with a guide buoyancy aid 8 in the support body 4, guide buoyancy aid 8 can carry out straight line motion effectively, be provided with the micro-discharge means 10 of a cover in the subsidiary cylinder 17, (micro-discharge means 10 is by stainless steel floating ball, lever, the trace safety check constitutes), valve body 1 place is provided with securing cover plate 2, and securing cover plate 2 tops are provided with bonnet 3, is provided with sealing gasket 11 between described securing cover plate 2 and the valve body 1, described securing cover plate 2 places are provided with pressure gauge assembly 9, are connected with nut 13 by bolt 12 between described bonnet 3 and the securing cover plate 2.
In concrete enforcement: when beginning water filling in the pipeline, buoyancy aid 8 rests on the position of unlatching, carries out a large amount of exhausts.Ponding in the valve body 1 along with increasing of ponding in the valve body 1, takes off in the support body 4 and enters water with entering the hole, holds up buoyancy aid 8, improves with water level, and until with sealing surface 5 contact seals, big round stops a large amount of exhausts.The micro-discharge means 10 of installation in the auxiliary valve body (stainless steel floating ball. lever, micro-safety check.) when spheroid descended, micro-safety check was opened, when water with the stainless steel floating ball jacking to horizontal line, micro-safety check promptly cuts out.
When water in the pipeline was normally carried, it was interior to certain degree to accumulate in valve body 1 if any little air, drawdown in the valve body, and stainless steel floating ball descends thereupon, and this moment, air was discharged by micro-safety check.When water pump stopped, when producing negative pressure in current sky and the pipeline in the pipeline, at this moment, big round, micro-safety check were opened rapidly, suck air.
