Abstract
The invention relates to an upper install ball valve, whose element is vertical to the water direction or the axle of water tube, wherein the invention has high control accuracy, stable property, and low rotation torque, while its idle rotation torque is not higher than 0.5N-m (0.05kgf-m); and the invention has high property than common ball valve, whose pressure resistance is improved from 1.6MPa to 3.5MPa. The inventive ball valve element is mounted on the valve body.
Description
(1) technical field:
The present invention relates to a kind of ball valve, particularly a kind of upper assembled electric ball valve for convenience detach of working under High Temperature High Pressure and the abominable water quality of continuous-flow that is applicable to.
(2) background technique:
With the high speed development of Chinese national economy, increasing to the demand of resource, especially protrude aspect water resources.China water resources occupancy volume per person has only 2710 cubic metres, is about world occupancy volume per person's 1/4, occupies the 88th in the world.More external national industrial waters are taked the cycling use of water measure already, and the recycling rate of waterused of water is up to about 70%～90%, and Chinese most city also rests on 20%～50% the level.Because process engineering falls behind, the industrial water quota also is higher than external advanced level far away.In order to guarantee the sustainable development of Chinese national economy, energy saving places on the agenda already, and this year, country strengthened energy-conservation dynamics, had put into effect corresponding laws and regulations.Self-contained electric system has used since the prepayment IC-card ammeter, prepay water meter and Prepayment Heat Meter are successively arisen at the historic moment, but what essential distinction is arranged with ammeter is that prepay water meter and Prepayment Heat Meter will be by the water of control valve opening and closing continuous-flow, and the key link of therefore controlling the prepayment metering instrument of fluid should be to improve the quality of control valve.
The prepayment metering instrument that China urban water supply system and heating central heating system use, basically use ordinary ball valve, have minority producer on the basis of ordinary ball valve, to adopt elastic element to improve the performance of ordinary ball valve, but because on the principle, the lifting of ordinary ball valve performance is limited.The prepayment metering instrument also can not be improved the performance of prepayment metering instrument control ball valve with the means that significantly raise the cost to the cost requirement of control simultaneously.From the following drawings 4 structural principle and the fit of the ordinary ball valve after the improvement in performance can be described, the ordinary ball valve after the improvement in performance (seeing accompanying drawing 4) (being called for short ordinary ball valve down) assemble sequence is:
Valve body 4-1 → along valve axis (down with) the O-ring seals I4-2 that the packs into → ball face sealing circle 4-3 that packs into → perpendicular to valve axis packs into, and rotating shaft 4-4 and the O-ring seals III4-6 → 4-8 ball of packing into → the ball face sealing circle 4-3 that the packs into → O-ring seals I4-2 that packs into → O-ring seals II4-5 and valve gap 4-6 pack into along valve axis (down with); From the assembling of ordinary ball valve as can be seen by valve body, O-ring seals I (2), ball face sealing circle (2), ball, O-ring seals II (2) and the valve gap error chains that form of totally 9 parts and the assembling chain contradictions that are difficult to solve the excellent sealing performance and the little moment of rotation of trying one's best; And ordinary ball valve proposed the higher processing precision requirement, increased manufacture cost.The control accuracy of ordinary ball valve and usability are the results of a plurality of part processing precision sum of errors assembly precision error stacks, as cause the malalignment and the degree of asymmetry of ball and ball face sealing circle and rotating shaft, the ordinary ball valve sealing are reduced and the moment of rotation increase.In addition, because the assembling active force acted on respectively on valve body and two parts of valve gap when ordinary ball valve was installed and used, it is loosening to be easy to cause valve body to be connected with valve gap, cause the seepage of supply channel, even cause the serious consequence of leaking in a large number, especially the consequence of the seepage of high-temperature-hot-water is very serious in the heating central heating system.Though ordinary ball valve has used 2 O-ring seals I to improve performances such as sealing that error chain and assembling chain cause and moment of rotation, but because the elastic deformation amount of O-ring seals I is limited, general distortion adjustment amount≤0.3-0.5mm is not enough to remedy sealing and the performance deficiency that above-mentioned reason causes.
(3) summary of the invention:
The objective of the invention is to design a kind of upper assembled electric ball valve for convenience detach, it is applicable under High Temperature High Pressure and the abominable water quality of continuous-flow and works, it is the good electric ball valve of a kind of control performance, it makes the control accuracy of control valve and usability is greatly improved and the change of principle type, is the indispensable high performance basic components of prepayment metering instrument of control fluid.
Technological scheme of the present invention: a kind of upper assembled electric ball valve for convenience detach, comprise ball valve body, the ball valve loam cake, spool, water intake, water outlet and electronic control unit, it is characterized in that having in the spool special-shaped ball face sealing circle, the silicone rubber elastic seal ring, O-ring seals I, O-ring seals II, O-ring seals III, teflon anti-attrition packing ring, rotating shaft, spheroid and fastening screw trip bolt are formed dismountable ball valve core assembly, said loam cake, spool, special-shaped ball face sealing circle, the silicone rubber elastic seal ring, O-ring seals I, O-ring seals II, O-ring seals III, teflon anti-attrition packing ring, rotating shaft, ball, the assembling of fastening screw trip bolt is perpendicular to the supply channel axial direction, and promptly its assembly direction becomes 90 ° with current axial direction or supply channel axial direction.
The elastic packing of being made up of special-shaped ball face sealing circle and silicone rubber elastic seal ring in the above-mentioned said spool is joined mating plate, and ball places the silicone rubber elastic seal ring of this idol part and the sphere of the special-shaped ball face sealing circle of teflon closely to contain.
