Abstract
The invention discloses a vacuum safety valve which comprises a valve body, a valve element, limiting pins and a connector. An opening hole communicated with the interior of the valve body is formed in the bottom end of the valve body, the valve element is arranged on the bottom face in the valve element in a pressing mode, the valve element can slide in the valve body, the limiting pins are fixedly installed on the top in the valve body, the connector is fixedly connected to the opening hole in the bottom end of the valve body, and multiple rows of pressuring releasing holes are formed in the side wall of the valve body. The vacuum safety valve is simple and reliable in structure, when the pressure in a vacuum container is rapidly increased to be equal to or higher than one barometric pressure in the absolute pressure due to a low-temperature pipeline or water pipe leakage in the vacuum container, the vacuum safety valve can be quickly and automatically started to release pressure, the phenomena that the vacuum container is deformed, fractured and even exploded and the like can be avoided, and thus the safety of the vacuum container is protected.
Description
Technical field
The present invention relates to Vacuum Field, particularly relate to the vacuum vessel that cryogenic piping or water pipe are housed, specifically a kind of antivoid valve being applicable to protection vacuum vessel.
Background technique
Along with vacuum technique is day by day deep in the application in the fields such as nuclear fusion, low-temperature superconducting, Aero-Space, the safety problem also ever more important of vacuum vessel.When vacuum vessel inner cryogenic pipeline or water pipe are revealed, vacuum vessel internal pressure increases rapidly, and vacuum vessel easily produces distortion, the phenomenons such as even blast of breaking.The safety valve that traditional pressure piping uses, needs reliable usage requirement of opening under close to environmental background pressure to meet to partial vacuum container.In order to address these problems, need on vacuum vessel design and installation can under close to environmental background pressure the reliable safety valve opened.
Summary of the invention
The object of the invention is to solve prior art Problems existing; there is provided a kind of simple structure reliable antivoid valve; when vacuum vessel inner cryogenic pipeline or water pipe leakage make vacuum vessel internal pressure be elevated to rapidly more than absolute pressure barometric pressure; this antivoid valve can open release pressure rapidly automatically; make the unlikely generation distortion of vacuum vessel, the phenomenons such as even blast of breaking, to protect the safety of vacuum vessel.
Technological scheme of the present invention is as follows:
A kind of antivoid valve, include valve body, spool, position limit pin and interface, it is characterized in that: the bottom of described valve body is provided with the perforate be connected with valve inner, described spool pressure is put on the bottom surface in described valve body, and spool can slide in described valve body, described position limit pin is fixedly mounted on the top in described valve body, and described interface is fixedly connected on the tapping of described valve body bottom, and the sidewall around described valve body is respectively equipped with arranges relief hole more.
Described antivoid valve, is characterized in that: the position that bottom is contacting with described valve body inner bottom surface of described spool is provided with annular groove and is provided with seal ring.
Described antivoid valve, is characterized in that: described interface adopts the fast connection interface of KF, and is connected with vacuum vessel by clip.
Described antivoid valve, is characterized in that: the aperture of described many row's relief holes increases from bottom to top successively.
Described antivoid valve, is characterized in that: the material of described valve body, spool, position limit pin and interface is aluminum alloy.
Described antivoid valve, is characterized in that: the material of described seal ring is fluorine rubber.
Beneficial effect of the present invention:
1, working stability of the present invention is safe and reliable, valve body can be made difformity and size to adapt to different vacuum vessels, and structure is simple, and cost is low, easy for installation.
2, spool of the present invention adopts simple and safe reliable structure, and when vacuum vessel inner cryogenic pipeline or water pipe are revealed and vacuum vessel internal pressure is elevated to rapidly more than absolute pressure barometric pressure, spool can open release pressure rapidly automatically; When being vacuum state in vacuum vessel, the sealing configuration that the interaction energy due to pressure reduction relies on safety valve to carry realizes vacuum seal automatically.
3, interface of the present invention adopts the fast connection interface of KF, installs and convenient disassembly.
Accompanying drawing explanation
Fig. 1 is structure sectional view of the present invention.
Fig. 2 is structural front view of the present invention.
Embodiment
See Fig. 1, 2, a kind of antivoid valve, include valve body 1, spool 3, position limit pin 4 and interface 6, the bottom of valve body 1 is provided with the perforate be connected with valve body 1 inside, spool 3 pressure is put on the bottom surface in valve body 1, and spool 3 can slide in valve body, position limit pin 4 is fixedly mounted on the top in valve body 1, during to prevent vacuum vessel internal pressure too high, spool 3 is ejected, interface solid 6 is surely connected to the bottom tapping of valve body 1 and is communicated with the inside of valve body 1, sidewall around valve body 1 is respectively equipped with many row's relief holes 5, communicate with outside atmosphere, with pressure too high in vacuum vessel of releasing out.
The position that bottom is contacting with valve body 1 inner bottom surface of spool 3 is provided with annular groove and is provided with seal ring 2.
Interface 6 adopts the fast connection interface of KF, and is connected with vacuum vessel by clip.
Many rows relief hole 5 elects three rows as, and often arrange eight, its aperture increases from bottom to top successively.
The material of valve body 1, spool 3, position limit pin 4 and interface 6 is aluminum alloy, with weight reduction.
The material of seal ring 2 is fluorine rubber.
Under vacuum vessel is in GPS survey vacuum work state, because vacuum vessel air pressure inside is lower, spool 3 by forming good sealing effect between seal ring 2 and valve body 1, thus makes cryogenic vacuum container be in an airtight system.When vacuum vessel inner cryogenic pipeline or water pipe leakage make vacuum vessel internal pressure be elevated to rapidly more than absolute pressure barometric pressure; spool 3 can automatically be opened under the effect of inside and outside differential pressure; by arranging relief hole 5 too high earth pressure release in air more; make the unlikely generation distortion of vacuum vessel, the phenomenons such as even blast of breaking, thus the safety of protection vacuum vessel.
The above is only possible embodiments of the present invention, and non-invention does any restriction the scope of the claims of the present invention, and the enforcement that all the present invention of disengaging do or change, all should be contained in the scope of the claims of the present invention.
