Description
Technical field
This utility model relates to LNG engineering valve technology field, particularly relates to a kind of ultralow temperature floating ball valve.
Technical background
Valve is in fluid system, is used for controlling the device of the direction of fluid, pressure, flow.Valve is to make the medium (liquid, gas, powder) in pipe arrangement and equipment flow or stop and controlling the device of its flow.
Valve is control parts in pipeline fluid induction system, and it is used to change path section and media flow direction, has the functions such as water conservancy diversion, cut-off, throttling, non-return, shunting or overflow release.For the valve that fluid controls, various valves used from simplest stop valve to extremely complex robot control system(RCS), its kind and specification are various, and the inside nominal diameter of valve reaches greatly the industrial pipeline valve of 10m from atomic little gauge valve to latus rectum.Valve can be used for controlling all kinds such as water, steam, oil product, gas, mud, various Korrosionsmedium, liquid metal and radioactive fluid and fluidly flows, the operating pressure of valve can supertension from 0.0013MPa to 1000MPa, operating temperature is from the ultralow temperature of-270 DEG C to the high temperature of 1430 DEG C.The control of valve can adopt the multiple kind of drive, as manually, electrically, surge, pneumatic, turbine, electromagnetic driven, electromagnetism surge, electro-hydraulic dynamic, air-or liquid-operated, spur gear, bevel gear driving etc.；Can under the effect of pressure, temperature or other form transducing signal, by predetermined requirement action, or it is independent of transducing signal and is simply turned on and off, valve relies on driving or automechanism makes opening and closing element lift, sliding, swing or gyration, thus the size changing its flow area controls function to realize it.
Development along with society, along with developing rapidly of the industries such as Modern Large tool, oil, chemical industry, new forms of energy, nuclear industry, the sealingly secure reliability requirement of valve is more and more high, and in the middle of cryogenic valve, lumen hypotony forms gas, in the gas of ultralow temperature, not having the circulation of medium, the very big hidden model of safety existed, in our existing technology, it is all that in adopting, cavity pressure reaches 1.33 times, releasing pressure automatically.But in actual ultralow temperature situation, very big difference is there is in designing and calculating with practical application, the ultra-low temperature ball valve pressure relief device of our design, there is outlet valve seat zero leakage, and LNG project is clean energy resource, environmental protection, so ultra-low temperature ball valve pressure relief device has wide market, will obtain a large amount of use.
Study not only easy for installation and firm and durable, and economic, energy-conservation and environmental protection valve, it appears particularly important.In prior art, 1. ultralow temperature floating ball valve, is all two way seal, reaches pass from valve, lumen is all have pressure forever, in LNG project, being all cryogenic valve, LNG is in ultralow temperature situation, it is all the compression gas of hundred times, when valve closing, the pressure of lumen will not produce circulation, there is the hidden model of very big safety.2. two way seal existing problems, import and the sealing of outlet, be desirable that sealing property is significantly high, and cost is high.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of safe and reliable, ultralow temperature floating ball valve that cost is low for the deficiencies in the prior art.
For solving above-mentioned technical problem this utility model by the following technical solutions: a kind of ultralow temperature floating ball valve, including valve body, described valve body is provided with valve seat, described valve seat is provided with spheroid, described spheroid is provided with communicating passage, described spheroid is provided with the through hole being connected with communicating passage.
Spheroid is provided with the through hole being connected with communicating passage, by through hole, inlet gas valve seat is connected with spheroid, define medium circulation, this ensure that the gas pressure of gas and whole pipeline defines an entirety, prevent lumen hypertonia, it is ensured that the safety of valve, realize again valve seat exit seal, ensure that the sealing property of valve export, it is achieved zero leakage.
As the further improvement of technique scheme, described through hole being radially arranged along spheroid.
As the further improvement of technique scheme, between described valve body and valve seat, it is provided with sealing member.
Further improvement as technique scheme, described valve body is fixedly connected with valve gap, it is provided with valve rod in described valve gap, one end of described valve rod is connected with spheroid, the other end of described valve rod passes valve gap and is connected to threeway handle, being provided with filler between described valve gap and valve rod, the outer end of described valve gap is provided with gland.
As the further improvement of technique scheme, described gland is connected by screw is fixing with valve gap.
As the further improvement of technique scheme, between described valve body and valve gap, it is provided with octagonal ring.
As the further improvement of technique scheme, described valve body is connected by screw bolt and nut is fixing with valve gap.
As the further improvement of technique scheme, described valve gap is provided with drip tray.
