Abstract
The utility model relates to the technical field of an exhaust valve, in particular to an improved exhaust valve, which comprises a valve body, an upper valve lid, a lower valve lid, a valve plate, a floating ball system and a diaphragm mechanism; the exhaust valve is characterized in that: the inner ring of the lower end surface of the upper valve lid is concave, the inner ring of the upper end surface of the lower valve lid is convex, the upper valve lid and the lower valve lid are embedded with each other and fixed to form a diaphragm room, the end surface of the upper valve lid is provided with a loophole, the loophole is connected with the ball valve, and the bottom end in one side of the upper valve lid is provided with a hole communicated with the environment. Compared with the prior art, the upper valve lid and the lower valve lid are embedded with each other, the seal in the valve lid is improved, and the abrasion of the fasten piece is avoided due to the vibration of the valve body, the fast exhaust mechanism is provided with the ball valve to control the conversion between the fast exhaust and the micro exhaust, the large quantities of exhaust are achieved under high pressure, thus avoiding the shortcomings that the exhaust valve which only has a small exhaust vent to exhaust under high pressure so the air in the pipe can not be completely exhausted.
Description
[technical field]
The utility model relates to the outlet valve technical field, specifically a kind of improved outlet valve.
[background technique]
Outlet valve is a requisite auxiliary element in the pipe-line system, be widely used in boiler, air-conditioning, petroleum gas, the water supply and sewerage pipeline, often be installed in commanding height or elbow etc. and locate, get rid of unnecessary gas in the pipeline, improve pipeline road utilization efficiency and cut down the consumption of energy.And the bottom flange end face is plane on more existing outlet valves, connects with fastening piece, easily weares and teares, and gas leakage under high pressure has only the small de-air hole exhaust, and air can't emptying in the pipeline.
[summary of the invention]
The purpose of this utility model is to overcome the prior art deficiency, is provided with the air-vent that can communicate with atmosphere on bonnet, and is realized the conversion of quick exhaust and micro-exhaust by ball valve switch air-vent.
For achieving the above object, design a kind of improved outlet valve, mainly comprise valve body, bonnet, bottom flange, valve plate, ball float system, diaphragm assembly, it is characterized in that: bonnet lower end surface inner ring is concavity, bottom flange upper-end surface inner ring is convex, the mutually chimeric fixing formation of last bottom flange diaphragm chamber, and the bonnet end face is established an air-vent, air-vent connects ball valve, and bottom flange one side bottom is established a hole that communicates with the external world in addition.
The utility model is compared with prior art, last bottom flange is chimeric, increased the seal in the valve gap, and the wearing and tearing of valve body vibration have been avoided to fastening piece, fast row in the mechanism is provided with the conversion that ball valve is controlled quick exhaust and micro-exhaust, realized a large amount of exhausts under the high pressure, avoided some outlet valves under high pressure to have only the small de-air hole exhaust, the defective that air can't emptying in the pipeline.
[description of drawings]
Fig. 1 is a structural representation of the present utility model.
Referring to accompanying drawing 1,1 is bonnet; 2 is air-vent; 3 is valve plate; 4 is ball valve; 5 is big exhaust port; 6 is bottom flange; 7 for the hole that communicates with the external world of bottom flange bottom; 8 is valve body.
[embodiment]
Below in conjunction with accompanying drawing the utility model is further described, the utility model is still more clearly concerning those skilled in the art.
Last bottom flange 1,6 edges are chimeric, fix with nut again, increased the seal in the valve gap, and the wearing and tearing of valve body vibration have been avoided to fastening pieces such as bolts, the diaphragm chamber that diaphragm assembly in the valve gap will be gone up bottom flange formation is separated into two districts up and down, if diaphragm top is bottom, A district is the B district, when the ball valve 4 that connects when the air-vent 2 of bonnet 1 is closed, the A district is air-tight state, the B district is because the hole 7 of establishing, bottom flange 6 bottoms and being communicated with atmosphere, gas enters outlet valve in pipeline, enter the A district by relevant actuator, make the barometric pressure of the air pressure in A district greater than the B district, diaphragm assembly moves downward, promote valve plate 3 and open downwards, make the air in the valve body 8 a large amount of by the big exhaust port on valve body 8 tops, discharge rapidly; Air is arranged the light time in pipeline, when only needing micro-exhaust, makes A district connection outside atmosphere and decompression as long as ball valve 4 opened, diaphragm assembly promptly quits work, and closes at the effect lower valve plate 3 of diaphragm assembly medi-spring, blocks big exhaust port 5, stop quick exhaust, change micro-exhaust over to.
