Abstract
The utility model relates to a composite total-pressure high-speed air exhaust valve, which belongs to the technical field of air exhaust valves. A valve cover is connected with a valve body through a support, and a spherical barrel as a driving part is arranged in the barrel-shaped valve body and is matched with a hollow valve sleeve with a hole at one side and a diaphragm moving mechanism to realize a great amount of air exhaust and micro air exhaust. Compared with the prior art, the utility model has simple and smooth structure, can realize a great amount of air exhaust under the high pressure, and has good air exhaust effect.
Description
[technical field]
The utility model relates to the outlet valve technical field, specifically a kind of combined type full-pressure high-speed exhaust valve.
[background technique]
Air valve is a requisite auxiliary element in the pipe-line system, is widely used in boiler, air-conditioning, petroleum gas, the water supply and sewerage pipeline, often is installed in commanding height or elbow etc. and locates, and gets rid of unnecessary gas in the pipeline, improves pipeline road utilization efficiency and cut down the consumption of energy.More existing outlet valves can't be implemented in the high speed exhaust under the total head, and complex structure.
[summary of the invention]
The purpose of this utility model is to overcome the prior art deficiency, adopts hydraulic principle, and ball float and valve rod are cooperated the quick exhaust in the aqueduct under the realization high pressure with the driving mechanism that diaphragm assembly forms.
For achieving the above object, design a kind of combined type full-pressure high-speed exhaust valve, mainly comprise valve gap, valve body, ball float etc., it is characterized in that: adopt support to be connected between the bottom flange of valve gap and the tubular valve body; Establish a ball tube in the tubular valve body, the built-in ball float of ball tube is as driver part, pyramid bonnet top axis hole is fixed the stopper of establishing axis hole in the middle of one, stopper is covered with a locking closure outward, the hollow shaft sleeve top is positioned at the stopper below, the hollow shaft sleeve the other end passes the diaphragm clamping plate that accompany diaphragm from top to bottom successively, the axis hole of bottom flange, the big exhaust port at valve body top, sheathed valve plate outside the bottom of hollow shaft sleeve, the hollow shaft sleeve bottom connects spool, hollow valve rod passes stopper from top to bottom successively, hollow shaft sleeve, spool, a copper plug screw is fixed by hollow core valve masthead portion, and hollow stem bottom connects the ball float sealing plug; Establish an aperture on the hollow shaft sleeve at place, nearly diaphragm clamping plate top; Sealing cover and chock plug that described ball float sealing plug is established spool bore by the centre are formed, and described spool bore cooperates with the spool size.A ball valve is established in the hole that establish in bonnet valve face left side, and ball valve is as the throw over switch of quick exhaust and micro-exhaust, and bottom flange is also established the hole of a connection atmosphere.The outer sheathed spring of hollow shaft sleeve between described diaphragm clamping plate below and the bottom flange.Establish a micro-exhaust port on the described locking closure.Establish a sealing gasket between described sealing cover and the plug.
The utility model is compared with prior art, and is simple in structure, smooth, adopts hydraulic principle, safe and reliable, exhausts in a large number under high pressure, good exhaust effect, because driver part has only accessory of ball float in water, even freeze in the valve, but still high speed exhaust after melting.
[description of drawings]
Fig. 1 is a structural representation of the present utility model.
Referring to accompanying drawing 1,1 is the copper plug screw; 2 is stopper; 3 is ball valve; 4 is the hole that is communicated with atmosphere on the bottom flange; 5 is hollow shaft sleeve; 6 is big exhaust port, is positioned at the valve body top; 7 is spool; 8 is valve body, is barrel shape; 9 is ball float; 10 is the ball tube; 11 is micro-exhaust port; 12 is locking closure; 13 is hollow valve rod; 14 is little inlet hole, is located at hollow shaft sleeve one side; 15 is spring; 16 is bonnet; 17 is bottom flange; 18 is support; 19 is valve plate; 20 is sealing cover; 21 is sealing gasket; 22 is chock plug; 23 is the diaphragm clamping plate, is made up of diaphragm clamping plate up and down; 24 is diaphragm; 25 is water intake, is the handing-over mouth of fluid pipeline and outlet valve.
[embodiment]
Below in conjunction with accompanying drawing the utility model is further described.
When the air of fluid pipeline inner accumulated enters valve body 8 through drain valve water intake 25, because air can't hold up ball float 9, the copper plug screw 1 at hollow valve rod 13 tops is blocked the axis hole of valve gap top stopper 2, the trace exhaust can't be carried out, this moment under pressure, the space of air between hollow shaft sleeve 5 and hollow valve rod 13 enters in the hollow shaft sleeve 5 in the valve body, at this moment, little inlet hole 14 on hollow shaft sleeve 5 one sides is positioned at the cavity place of valve gap, it is indoor that the thus little inlet hole 14 of air enters the valve cover cavity on diaphragm 24 tops, and the valve gap chamber of diaphragm 24 bottoms is owing to be provided with the hole 4 that is communicated with atmosphere, therefore upper chamber's air pressure is greater than the lower chambers air pressure, and with diaphragm 24 to pressing down, diaphragm clamping plate 23 drive hollow shaft sleeve 5 again and move downward, valve plate 19 is opened, and air is discharged fast through big exhaust port 6 in the valve body.
When water enters outlet valve valve body 8, ball float 9 is held up, with hollow valve rod 13 jack-up, little inlet hole 14 risings of hollow shaft sleeve 5 one sides enter the closure of bonnet 16 and are plugged, and the copper plug screw 1 at hollow valve rod 13 tops upwards leaves the axis hole of stopper 2, therefore, air is through hollow shaft sleeve 5, again through the axis hole of stopper, micro-exhaust port 14 from the locking closure 12 is discharged, and when liquid constantly rises, final spool 7 embeds in the spool bore of ball float sealing plug top seals lid 20, outlet valve stops exhaust, stops the outflow of liquid simultaneously.
After air is discharged from, under the reaction force of spring 15, with diaphragm clamping plate 23 jack-up upwards, hollow shaft sleeve 5 also rises thereupon, drives valve plate 19 and rises, and blocks big exhaust port 6, air row light in pipeline is when only needing micro-exhaust, as long as ball valve 3 is opened the connection ambient atmosphere, upper chamber in the valve gap is a decompression, outlet valve stops quick exhaust, and carries out micro-exhaust, is in operation as pipeline and assembles a large amount of air easily, ball valve can be placed on closed position always, so that a large amount of exhaust in service.
