End.Any of the above sensor can use micro sensing element, and be arranged in valve body tube is specific
Position, it is also possible to draw from valve body tube a branch line be specifically designed to detection various parameters make
With, thus the through-flow performance of valve body tube is not had a negative impact.The mould related in such scheme
Block, circuit and electronic devices and components can use design generally in the art and scheme, it is possible to
To use special design according to specific needs.
This programme has also made improvement in terms of the material of ball valve made of plastic, uses a kind of PVC to mix
Material, combines PVC material and the advantage of MPOE material, uses CPE to improve both materials
The consistency problem of material, notice simultaneously valve possible application in the dark space of interval,
Luminous agent is added so that valve body can be luminous in the dark environment such as night, just in batch mixing
In personnel's identification and maintenance.The specifically material of ball valve made of plastic is a PVC batch mixing, PVC batch mixing
By 55% mass percent PVC, 30% mass percent filling master batch, 11% mass percent CPE,
2% mass percent flow ability modifying agent and 2% mass percent luminous agent strontium aluminate composition, fill
Masterbatch is by 70% mass percent calcium carbonate, 28% mass percent MPOE and 2% mass percent
Silane coupler forms.It is good that PVC (polrvinyl chloride) has processing characteristics, low cost of manufacture,
Corrosion-resistant, the features such as insulating properties is good, material applications is extremely wide, is used for plastic pipe molding.
MPOE is POE graft modification body, and POE (polyethylene octene elastomer) is a kind of elastic composite
Material, has the toughness of excellence and good processability, does not has unsaturation in POE molecular structure
Double bond, has excellent ageing-resistant performance, POE narrow molecular weight distribution, has preferably flowing
Property, its good mobility can improve the dispersion effect of filler, it is also possible to improves the molten of goods
Lapping defect intensity.In filling master batch, the consumption of calcium carbonate (inorganic filler) is in its mass percent 70%
Time, the impact strength of batch mixing reaches optimal, being increased or decreased with its consumption, and impact strength is all
Can decline in various degree.In reality, PVC material is blended with MPOE material and there is consistency problem,
In order to solve this problem, this programme have employed CPE (chlorinated polyethylene) bulking agent, experiment card
Bright holding inorganic filler consumption is constant, and CPE consumption increases, and the impact strength of batch mixing increases,
When CPE consumption is 11% mass percent, in the case of batch mixing impact strength ratio is not added with CPE
Add more than 4 times.The addition of flow ability modifying agent improves the mobility of filling master batch, it is suppressed that
MPOE thermal degradation effect in the course of processing, when its consumption is 2% mass percent, fills out
Fill in the case of the torque ratio of masterbatch is not added with flow ability modifying agent and reduce 25%, the impact strength of batch mixing
Preferably, hot strength is basically unchanged.Strontium aluminate is a kind of chemical substance light yellow, non-flammable,
Density is relatively bigger than water, and chemical property torpescence, is the thing that mainly comprises of fluorescent material, this
Luminescent material is placed in dark surrounds after by ultraviolet or radiation of visible light can send fluorescence,
It is demonstrated experimentally that strontium aluminate irradiates about 20 minutes under daylight or light, can be in dark
Continuous illumination about 10 hours in environment, its absorb and the process of radiant can repeat into
OK, it is preferable fluorescent material.In above scheme, unspecified concrete chemical substance can be adopted
With material generally in the art, use general implementation or formula, it is also possible to according to specifically
Situation uses special material and formula and makees known adaptive change on general scheme.
The ball valve made of plastic of this programme uses valve sphere radially adapter sleeve parts and valve sphere the tightest
Gu ring component enhances valve sphere at the stability within valve body tube and sealing, employing sealing ring
The sealing property at pipe interface is enhanced with sealing the sealing fit system that compresses compressing boss,
Ball valve sealing property when with the pipeline connection of different tube diameters is guaranteed, uses outside being easy to
The valve ball anglec of rotation indicator that portion is observed indicates the folding degree of valve, uses remote-controlled electricity
Dynamic switching system controls the switch of valve, have employed the measurement of various liquid parameter sensors and feeds back it
Relevant parameter, uses PVC and MPOE batch mixing to improve the performance of ball valve material, luminous agent simultaneously
Addition make ball valve be prone to be identified under dark surrounds, it is simple to safeguard.Based on above feature,
The ball valve made of plastic of this programme is compared existing like product and is had prominent substantive distinguishing features and show
The progress write.
The ball valve made of plastic of this programme is not limited to detailed description of the invention part disclosure, wherein
The technical scheme occurred can be with individualism, it is also possible to mutually comprise, those skilled in the art's root
Combine, according to this programme, the simple alternative that common knowledge makes and fall within the scope of this programme.
