Description

Low-power consumption energy-saving electric ball valve

Technical field

This utility model belongs to low-power consumption electrically operated valve technical field, is specifically related to a kind of low-power consumption energy-saving electric ball valve.

Background technology

Electrically operated valve is widely used in the fields such as municipal water supply, HVAC, commercial production, agricultural irrigation, and along with the raising of science and technology automaticity, the intelligentized control method demand of valve is more and more wider.The mechanical realization of traditional electrically operated valve is not suitable for low-power consumption DC micro-electric voltage source and drives, at present, low-power consumption direct current supply large bore valves many employings pilot-operated-type electric valve door of existing use, and owing to pilot-operated-type electric valve door main body structure mostly is cut-off type, so it is excessive to cause the pressure loss, negotiability is poor, and structure is complicated, the shortcomings such as use occasion is single, greatly reduce the range of low-power consumption electrically operated valve.

How by the improvement of prior art, using ball valve conducting technology, it is achieved homalographic leads directly to medium, and negotiability is strong, and volume is little, the advantage of no pressure loss, is existing industry technical staff technical problem urgently to be resolved hurrily.

Summary of the invention

The problem existed for prior art, the purpose of this utility model is to provide a kind of low-power consumption energy-saving electric ball valve, its technical scheme used by its technical problem of solution is as follows: a kind of low-power consumption energy-saving electric ball valve, including a fixed valve body, the lower section of valve body is equipped with spheroid core, spheroid core right angle setting, it is fixed to one with valve body by bearing bottom it, the top of spheroid core is through bonnet and extends to executor and controls in box, spheroid core and bonnet junction are fixed with a bearing and two O, described bearing is arranged on the lower section of O, the top of spheroid core is fixed as one by shaft coupling and YE；Described executor controls box and is bolted on bonnet top, and bonnet is fixed as one by bolt and valve body, and bonnet and valve body junction are fixed with a circle sealing gasket；On valve body, the right side of spheroid core is liquid outlet, the left side of spheroid core is inlet, the left side of spheroid core is provided with piston, inlay between piston and spheroid core and be fixed with phenyl tetrafluoride pad, the left side of piston is spring, and the left end of spring is installed on inside inlet, and the inwall junction of piston and valve body is provided with twice O.

On described valve body, a spiracle has been got through on the inwall of valve body and piston contact position, and described spiracle is arranged between twice O and communicates outside valve body.

The beneficial effects of the utility model: this utility model is by inlaying sealing gasket on valve seat, and closely touch with spheroid core side, with the pressure of pipeline medium own and spring auxiliary pushing piston, ensure its sealing property, the extruding moment of the original fixed valve seat of piston overpowers and spheroid core, driving in conjunction with the YE at spheroid core top, spheroid core is driven to rotate, thus alleviate the moment of torsion of switch, solve a difficult problem for the low power consumption control switch of big-diameter ball valve, the advantage that this utility model takes full advantage of spheroid core, making this utility model have more homalographic, to lead directly to medium negotiability strong, volume is little, the advantage of no pressure loss.

Detailed description of the invention

A kind of low-power consumption energy-saving electric ball valve, including a fixed valve body 1, the lower section of valve body 1 is equipped with spheroid core 8, spheroid core 8 right angle setting, pass through bearing 9 be fixed to one with valve body 1 bottom it, the top of spheroid core 8 is through bonnet 2 and extends to executor and controls in box 11, spheroid core 8 and bonnet 2 junction are fixed with a bearing 9 and two O 5, described bearing 9 is arranged on the lower section of O 5, spheroid core 8 two bearings setting up and down, can effectively ensure that when YE 5 drives spheroid core 4 to rotate, running resistance is little；The top of spheroid core 8 is fixed as one by shaft coupling 13 and YE 12；Described executor controls box 11 and is fixed on bonnet 2 top by bolt 14；On valve body 1, the right side 15 of spheroid core 8 is liquid outlet, the left side of spheroid core 8 is inlet 16, the left side of spheroid core 8 is provided with piston 3, inlay between piston 3 and spheroid core 8 and be fixed with phenyl tetrafluoride pad 4, the left side of piston 3 is spring 7, and the left end of spring 7 is installed on inside inlet 16, and the inwall junction of piston 3 and valve body 1 is provided with twice O 5.

Valve body 1 described in the utility model it should be noted that when assembling that bonnet 2 is installed to one by bolt 14 and valve body 1, for ensureing the sealing that bonnet 2 and valve body 1 are installed, is provided with a sealing gasket 14 between bonnet 2 and valve body 1；Executor is controlled the bottom of box 11 and is installed to one by bolt 14 and bonnet 2.

On described valve body 1, a spiracle 6 has been got through on the inwall of valve body and piston contact position, described spiracle 6 be arranged between twice O and and the outside of valve body 1 communicate, its effect is to be automatically adjusted valve body 1 inside and outside pressure, plays the effect balancing valve body 1 inside and outside pressure differential.

nullWhen this utility model runs，This utility model is by inlaying phenyl tetrafluoride pad 4 between piston 3 and spheroid core 8，And closely touch with spheroid core 8 side，With valve body 1 pressure of internal pipeline medium own and spring 7 auxiliary pushing piston 3，Ensure its sealing property，Piston 3 overcomes the extruding moment of original fixed valve seat and spheroid core 8，Thus alleviate the moment of torsion of switch，Again by being respectively set with a bearing 9 on the arbor at spheroid core about 8 two ends，Greatly facilitate smoothness when spheroid core 8 rotates，Effectively reduce resistance when spheroid core 8 rotates，Decrease the power consumption of YE 12，Solve a difficult problem for big-diameter ball valve low power consumption control switch，The advantage that this utility model takes full advantage of spheroid core，Making this utility model have more homalographic, to lead directly to medium negotiability strong，Volume is little，The advantage of no pressure loss，Can be at municipal water supply、HVAC、Commercial production、The fields such as agricultural irrigation are widely popularized.
