Description
Technical field
The utility model belongs to engineering goods field, relates in particular to a kind of hydraulic pressure double-opening exhaust valve.
Background technique
Outlet valve is installed on the likely place of high speed intake and exhaust, gets rid of at a high speed ducted air during water-filling, and it is unobstructed that when pipeline emptying, air amount keeps draining, when pipeline is normally worked, can constantly get rid of the air of separating out.When likely producing water hammer, air is entered automatically, avoid producing negative pressure, prevent or slow down the harm of water hammer, double-opening exhaust valve is a kind of in outlet valve, its principle is while starting water filling in pipe, chock plug rests on enable possition, carry out a large amount of exhausts, when air is drained, valve internal water accumulation, ball float is floated, transmission chock plug is to closed position, stop a large amount of exhausts, when in pipe, water is normally carried, if any a small amount of air accumulation, in valve, arrive certain degree, in valve, water level declines, ball float declines thereupon, now air is discharged by aperture, when suction engine stops, when in-pipe flow is empty or while meeting the interior generation of pipe negative pressure, now chock plug is opened rapidly, air amount, guarantee that pipeline is complete.
For example Chinese patent 201220317289.6 discloses a kind of simple in structure, can prevent that foreign material from entering in valve body, good exhaust effect, can ensure waterline safety, the double-opening exhaust valve of long service life, comprise valve body, valve rod and flap, valve body lower portion offers the valve port that supplied gas and fluid enter, valve body top is provided with valve gap, flap can be located on valve port in folding, valve rod can oscilaltion be located in valve body, its one end and flap are connected, the other end stretches out outside valve gap and is connected with drive unit, the left and right sides of valve body is respectively equipped with the left side being connected with valve port, right exhaust chamber, left, in right exhaust chamber, be respectively equipped with ball float, valve body is positioned at a left side, the top of right exhaust chamber is also respectively equipped with exhaust end cover, on each exhaust end cover, be respectively equipped with relief opening, the top that valve body is positioned at exhaust end cover and valve gap is also provided with protecting cover, between protecting cover and two exhaust end covers, be provided with the gap that supplied gas flows out, the inside circumference that valve body is positioned at valve port is provided with filter screen.
The double-opening exhaust valve implementation result of this structure is not satisfactory, when pressure in pipeline is lower, relief opening can be opened or close to ball float in outlet valve, once the pressure in pipeline is larger, because the seal of ball float and exhaust port is bad, be easy to occur intravenous extravasation phenomenon, thereby cause outlet valve malfunctioning, if liquid has corrosivity, that brings potential safety hazard to environment and human body.
Summary of the invention
The utility model provides a kind of hydraulic pressure double-opening exhaust valve, the problem of easily exosmosing to solve the liquid in pipe that proposes in above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions: the utility model provides a kind of hydraulic pressure double-opening exhaust valve, it is characterized in that: comprise valve seat, described valve seat both sides are provided with valve A, valve B, in described valve A, be provided with ball float A, on described valve A, be fixed with valve gap A, between described valve gap A and valve A, be provided with gasket seal A, described valve A, valve gap A, on gasket seal A, be provided with exhaust port A, in described valve B, be provided with ball float B, on described valve B, be fixed with valve gap B, between described valve gap B and valve B, be provided with gasket seal B, described valve B, valve gap B, on gasket seal B, be provided with exhaust port B, described valve A, valve B outside is covered with protecting cover, described protecting cover and valve A, valve B forms an airtight cavity, described exhaust port A, exhaust port B all communicates with described cavity, described protecting cover is bolted on described valve gap A, on valve gap B, described valve A, between valve B, be provided with valve rod fixed base and be arranged on the valve rod on valve rod fixed base, on described protecting cover, be provided with cylinder body, described cylinder body top is provided with air outlet hole, the other end of described valve rod is arranged in described cylinder body through described protecting cover, described valve rod inner hollow, described valve rod inside is provided with piston rod, described piston rod is connected with piston, described piston is positioned at the top of described cylinder interior, the both sides of described valve rod are provided with oil discharge passage.
The quantity of described oil discharge passage is 8, and symmetry is set up in parallel.
Described valve rod fixed base is provided with groove, and described valve rod is positioned at described groove.
The beneficial effects of the utility model are: the utility model is at valve A, the outside of valve B has increased the protecting cover of a sealing, once make the liquid in pipeline occur exosmosing, just flow directly in cavity, rather than outdoor, especially for mordant liquid, avoid environmental pollution and the person is caused to damage, and the fluid storage in cavity can also flow back in pipeline after a certain amount of, do not waste, owing to being provided with sealed cavity outward at exhaust port, the control of valve rod has just adopted the hydraulic control that pressure is larger, to normally work in the situation that cavity internal pressure is larger, piston rod is set to hollow, and by the valve rod portion that sets within it, just can save the setting of hollow sleeve, make structure more compact.
