Description
Technical field
This valve relates to technical field of valve manufacturing, particularly relates to a kind of valve.
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.For the valve of fluid control systems, from simplest stop valve to extremely complex from
Various valves used in Ore-controlling Role, its kind and specification are the most various.Valve can be used for controlling sky gas and water, steam, various corruption
The flowing of all kinds fluids such as erosion property medium, mud, oil product, liquid metal and radiating medium.Valve also divides according to material
For cast iron valve, cast steel valve, stainless valve (201,304,316 etc.), chrome-molybdenum steel valve, Chrominm-molybdenum-vanadium steel valve, dual phase steel
Valve, Plastic valve, nonstandard customized valve material such as grade.
In the pipeline of transmission liquid, need to use valve to control the circulation of liquid, tied by changeover valve cavity
Structure and the opening degree of valve plate, realize the control to the circulation size transmitting liquid.In the pipeline of full liquid, valve
One end contact with each other with liquid, the cavity structure of valve and the contact position of valve plate are the highest to the requirement of sealing, if close
The bad liquid of envelope property easily enters so that valve it would appear that still there is the seepage of liquid when the state of valve closing, it is impossible to
Fasten thoroughly, the serviceability of valve can be severely impacted.Solve this problem, it will usually use and tie at valve cavity
Valve pocket is installed so that the cavity of valve and valve plate keep good sealing, it is ensured that the normal work of valve on structure.Generally
In the case of, can directly valve pocket be fixedly installed on one end of the cavity structure of valve, but, owing to valve pocket often connects with liquid
Touching, valve pocket is easily corroded, and during using, the damage of the pipe box on valve will cause the reduction of valve serviceability very
To may result in scrapping of valve, seriously reduce the service life of valve.In order to save the cost of equipment, design a
The sealing between the cavity structure of valve and valve plate can be kept, facilitate again the replacing of valve pocket, improve the service life of valve
Valve pocket mounting structure and valve be extremely necessary.
Valve plate is the important component part of pipeline valve, is mainly used for being arranged on pipeline, carries out the flow of liquid
Control, to reach to cut off and the purpose of throttling.Owing to valve is mostly installed at the pipeline opening of conveying liquid, when carrying liquid
By controlling valve plate in the valve aperture in the mouth of pipe, to realize the control of the flow to liquid.Therefore, valve plate is controlling
Bigger pressure is subject, in order to prevent valve from ftractureing, it is generally the case that the thickness of valve plate can be processed during flow
Thicker so that valve plate can resist the powerful pressure of liquid in pipeline.But this means that and to produce a valve
More material will be needed, considerably increase the manufacturing cost of producer.In order to better meet people in productive life
Upper demand, on the one hand, reduce the material of valve plate on manufacturing as much as possible, saves production cost；On the other hand so that valve
Plate can bear bigger pressure as much as possible, extends the service life of valve, can obtain bigger during using
Safety guarantee.Generally speaking, producing a kind of cost performance high, valve plate that usability is strong and the valve applying this valve plate are will be right
Pipeline valve field has a very important role.
The patent documentation of Patent No. 201320378594.0 discloses a kind of rotary opening and closing fluid pipeline valve, including valve
Set, valve plate, valve rod；Described valve pocket has two perforates passed for valve rod two ends, and a tapping is provided with and turns for righting
The axle sleeve of dynamic state valve rod, another tapping is provided with the overcoat pinning valve rod；Two fixing seats, institute are installed on described valve plate
Stating and respectively have a circular hole identical with the diameter of described valve rod on fixing seat, described valve rod is through circular hole and through described valve plate
The center of circle；Described valve rod is welded and fixed with fixing seat, its one end through described valve pocket perforate and with described outer cover locking, the other end
Pass circular hole and the axle sleeve of described valve pocket.
There is, when this kind of valve pipe mainly solves to close valve, the problem wasted time and energy.But owing to valve rod is with solid
Reservation is weldingly fixed on valve plate, and valve rod directly contacts with liquid phase with fixing seat, it will cause valve rod and fixing seat and valve plate
Chronically by liquid corrosion so that valve rod is the most damaged with fixing seat.Substantially reduce valve rod and the service life of fixing seat,
Need to change together with valve rod and fixing seat while changing valve plate, so waste production valve rod former with the manufacture of valve
Expect and substantially increase the manufacturing cost of pipeline valve.
Therefore, design one and valve rod and valve seat can be prevented to be corroded, extend the installation of the valve plate in the service life of valve
Structure and valve are the most significant.
