Abstract
The invention provides an exhaust valve. The exhaust valve comprises a main valve body, a one-way valve body and a floating drum. The floating drum is located in a cavity of the main valve body. The bottom end of a one-way valve stretches into the main valve body. Elastic parts are connected between the bottom of the floating drum and the inner wall of the bottom of the main valve body. The top of the floating drum is provided with an annular joint. The bottom of the one-way valve body extends to the annular joint. A floating ball is arranged in the one-way valve. The bottom of the one-way valve is provided with a support segment and the top of the one-way valve is provided with a stop segment. The top of the one-way valve is provided with a sealing plug, the middle of which is provided with a through hole. The floating ball is restrained by the elastic parts and floats up and down under the elastic force. Sometimes the bottom of the one-way valve body is separated from the annular joint and sometimes the bottom of the one-way valve body is attached to the annular joint for intermittent exhaust. The floating ball floats up and down so that a part of liquid entering the main valve body is exhausted out of an air inlet, thereby preventing liquid from splashing out of the one-way valve body.
Description
Technical field
The present invention relates to valve technology field, be specifically related to a kind of outlet valve.
Background technique
In order to reduce the pressure in fluid-transporting tubing, often in fluid feed line, outlet valve is installed, when carry fluid be high temperature, there is corrosivity or poisonous time, just very high to the requirement of the sealing of outlet valve, first liquid can not be discharged in outlet valve, avoids equipment, damages the person, secondly, exhaust efficiency wants high, the forceful impacts avoiding pipeline too high pressure not to be vented in time making part in twin conduit or cause bursting apart of pipeline.
Summary of the invention
For solving the problems of the technologies described above, technological scheme provided by the invention is: a kind of outlet valve, comprise main valve body, check valve body, floating drum, the suction port of outlet valve is positioned at the bottom of outlet valve, the air outlet of outlet valve is positioned at outlet valve top left side position, described floating drum is positioned at described main valve body cavity, described one-way valve bottom is stretched in described main valve body, described main valve body is stretched out along the air outlet of described main valve body in its top, elastic component is connected with bottom described floating drum and between described main valve body bottom interior wall, ring interface is provided with at described floating drum top, extend to bottom described check valve body in described ring interface, ball float is provided with in described one-way valve, supporting section is provided with bottom described one-way valve, its top is provided with stop section, described one-way valve top is provided with sealing plug, through hole is provided with in the middle of described sealing plug.
Further, be provided with O-ring seal in described ring interface, described O-ring seal is quality of rubber materials.
Further, the internal diameter of described ring interface equals the external diameter of described check valve body and the double thickness sum of described O-ring seal.
Further, the distance that described relative stop is intersegmental is less than the diameter of described ball float.
Further, the distance that described relative support is intersegmental is less than the radius of described ball float.
The advantage that the present invention has and beneficial effect are:
1, outlet valve exhaust efficiency provided by the invention is high, ball float pins down by elastic component, fluctuate under elastic force effect, be separated bottom check valve body with during ring interface, time and fit, intermittent exhaust, can avoid excessive check valve body and the ring interface of making of buoyancy to close for a long time, causes liquid to be full of main valve body intracavity pipeline internal pressure and can not get release;
2, outlet valve provided by the invention can prevent liquid from discharging in one-way valve, the a part of liquid entered in main valve body can be discharged from suction port under downward elastic force effect when ball float fluctuates, thus avoid liquid to be full of main valve body and then spill in check valve body.
Accompanying drawing explanation
Fig. 1 is the section of structure of outlet valve provided by the invention.
In figure: 1. main valve body, 2. suction port, 21. air outlets, 3. floating drum, 4. ring interface, 5. O-ring seal, 6. elastic component, 7. check valve body, 8. supporting section, 9. ball float, 10. stop section, 11. sealing plugs, 12. through holes.
Embodiment
Illustrate below in conjunction with accompanying drawing and the specific embodiment of the present invention is elaborated.
As shown in Figure 1, the invention provides a kind of outlet valve, comprise main valve body 1, check valve body 7, floating drum 3, the suction port 2 of outlet valve is positioned at the bottom of outlet valve, the air outlet 21 of outlet valve is positioned at outlet valve top left side position, described floating drum 3 is positioned at described main valve body 1 chamber, described one-way valve bottom is stretched in described main valve body 1, described main valve body 1 is stretched out along the air outlet 21 of described main valve body 1 in its top, elastic component 6 is connected with bottom described floating drum 3 and between described main valve body 1 bottom interior wall, fluctuate at elastic force effect lower pontoon 3, be separated with during ring interface 4 bottom check valve body 7, time and close, intermittent exhaust, excessive check valve body 7 and the ring interface 4 of making of buoyancy can be avoided to close for a long time, cause liquid to be full of main valve body 1 intracavity pipeline internal pressure and can not get release,
Ring interface 4 is provided with at described floating drum 3 top, extend to bottom described check valve body 7 in described ring interface 4, ball float 9 is provided with in described one-way valve, supporting section 8 is provided with bottom described one-way valve, its top is provided with stop section 10, described one-way valve top is provided with sealing plug 11, is provided with through hole 12 in the middle of described sealing plug 11.
Wherein, the internal diameter of described ring interface 4 equals the external diameter of described check valve body 7 and the double thickness sum of described O-ring seal 5, when floating drum 3 is fluctuated, ring interface 4 fits tightly slip along check valve body 7 outer wall, further, be provided with O-ring seal 5 in described ring interface 4, described O-ring seal 5 is quality of rubber materials, avoids the liquid when liquid rises on floating drum 3 to enter in check valve body 7 from the gap between ring interface 4 and one-way valve.
Wherein, the distance between described relative support section 8 is less than the radius of described ball float 9.When in main valve body 1, pressure is less, ball float 9 is seated on relative supporting section 8, ball float 9 is blocked gas and is discharged in check valve body 7, when pressure in main valve body 1 increases, ball float 9 moves, and gas flows in check valve body 7 bottom check valve body 7, further, distance between described relative stop section 10 is less than the diameter of described ball float 9, avoids ball float 9 to go out check valve body 7.
