Description
Technical field
The present invention relates to one efficiently slow down flow control valve, belong to control valve field.
Background technology
Valve (valve) is the control parts in fluid delivery system, has cut-off, regulation, water conservancy diversion, prevents countercurrently, surely
The functions such as pressure, shunting or overflow pressure relief.
Valve is in fluid system, be used for controlling the direction of fluid, pressure, the device of flow be make pipe arrangement and equipment in
Medium (liquid, gas, powder) flow or stop and controlling the device of its flow.
Valve is control parts in pipeline fluid induction system, is used for changing path section and media flow direction, has
Water conservancy diversion, end, throttle, non-return, the function such as shunting or overflow release.The valve controlled for fluid, from simplest stop valve
Various valves used in extremely complex robot control system(RCS), its kind and specification are various, and the inside nominal diameter of valve is from atomic little
Gauge valve reach greatly the industrial pipeline valve of 10m to latus rectum.Can be used for controlling water, steam, oil product, gas, mud, various corrosion
The all kinds such as property medium, liquid metal and radioactive fluid fluidly flow, and the operating pressure of valve can be from
The supertension of 0.0013MPa to 1000MPa, operating temperature can be with the high temperature of the ultralow temperature to 1430 DEG C of c-270 DEG C.
The control of valve can use 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 be at pressure, temperature or the work of other form transducing signal
Under with, by predetermined requirement action, or being independent of transducing signal and be simply turned on and off, valve relies on and drives
Or automechanism makes opening and closing element lift, sliding, swing or gyration, thus change the size of its flow area to realize
It controls function.

Become the intermediate diameter portion between described diameter portion and described small diameter portion；Described seating portion by described little directly
Radially-inwardly prominent formation near region neighbouring with described intermediate diameter portion on path portion.
Its advantage is: accessory body and seat component are all made up of separate body, and owing to tubular holder component can be integrally
Assemble and be connected to the end portion of accessory body, therefore can effectively it be assembled, and manufacture the same of flow control valve
Shi Tigao productivity ratio.
But shortcoming is: structure is the most complicated, maintenance cost is high.
Application No.: heat water control valve disclosed in 200810171460.5, including: tubular dispenser joint, its
There is the first threaded portion threadeded the coupling part with water dispenser and have than the first threaded portion larger diameter
Second threaded portion；Tubular body, has at its first end and connects the pipe joint of heating pad pipe and have bigger more straight than pipe joint
3rd threaded portion in footpath, and the end of the second threaded portion is contacted at its second end；First connector, is arranged on main body
The second end, thus do not depart from main body and threaded with the second threaded portion of distributor joint, thus connect allotter
Joint and main body；Dead ring, is arranged on the periphery of the heating pad pipe being connected with pipe joint；Second connector, with the 3rd spiral shell of main body
Stricture of vagina partial threads connects and fixes dead ring, thus prevents heating pad pipe from departing from from pipe joint；O, is arranged on distributor joint
The second threaded portion and main body between be used for preventing leakage；Shape memory spring, is arranged on the inner side of main body near allotter
Joint；Elastic spring, is arranged on the inner side of main body near pipe joint；With hat shape ball valve, it is arranged on shape memory spring and elastic force
Between spring thus open and close the outlet of pipe joint selectively.Its advantage is: according to the heat water control of the present invention
Valve processed, the heat water flowing through heating pad pipe can be according to the temperature automatic control of heating water.Thus, equilibrium heating can not consider
The length of heating pad pipe and boiler realize in the case of the distance of heating pad pipe (or room).Accordingly, it is capable to can uniformly and effectively
Ground utilizes.
But above-mentioned valve mechanism is complicated, if one of them parts goes wrong, may result in whole valve and occur
Fault, and due to the emergency problem of flow rate of liquid, cause valve self coutroi velocity ability to reduce, and then just affect valve
Often duty.
