Abstract
The invention discloses a flow-distribution plate of an electric ball valve and an assembling method of the flow-distribution plate. The flow-distribution plate has a spherical structure, a V-shaped opening is left on the flow-distribution plate with the spherical structure, the flow-distribution plate is assembled in a valve core, the valve core is arranged in a valve body by a valve seat, and a valve rod is connected with the valve core, thereby forming the electric ball valve. The assembling method of the flow-distribution plate comprises the following steps: the flow-distribution plate is pressed in the valve core by a press and a customized pressing head by utilizing the interference fit principle of an axle hole, so that the valve core and the flow-distribution plate are integrated. As the flow-distribution plate is pressed in the valve core of the electric ball valve, the valve core and the flow-distribution plate are combined into one body, so as to be adaptive to the demands of flow characteristic curves of the electric ball valve. The flow-distribution plate has the advantages that the manufacturing is easy, the assembly is convenient, the comprehensive cost is low and the flow rate regulating precision is high. The flow-distribution plate and the assembling method are suitable for manufacturing the electric ball valve and regulating the flow rate of the electric ball valve in the industrial flow state control field.
Description
Technical field
What the present invention relates to is electric ball valve thrust plate and the assembly method that industrial field is used to regulate liquid or gas flow.
Background technique
Thrust plate is to realize the characteristic core component of ball valve different flow.
Electric ball valve in the building automatic control mainly adopts the equal percentage flow characteristic curve, mainly be that non-linear output characteristics to heat exchanger in the heating ventilation air-conditioning system compensates, also have is individually that employing waits the linear flow discharge curve, and according to on-the-spot needs difference, the characteristic curve that requires is also different with the Kvs value, just can satisfy above demand if partly increased thrust plate at the electric ball valve spool.
The fit of tradition thrust plate is that the entrance point at valve body adds a flat thrust plate with equal percentage curve, this thrust plate is mounted in beyond the spool, when electric ball valve is worked, it does not rotate moving thereupon during valve core rotation, because thrust plate is plane structure, and after the electric ball valve spool is spherical result, make to have space length between thrust plate and the spool, therefore can not fit fully, weaken the realize ideal ability of rating curve of ball valve.Therefore the electric ball valve rating curve of flat static thrust plate is difficult to the effect that reaches desirable.
Therefore in traditional application in order to reach better rating curve, what generally adopt in the industry electric ball valve is " V-type ball " structure, on the spool of circle, open the hole of a V-type exactly, rather than circular hole, with the V-shape hole shape realize equal percentage curve or etc. linearity curve, this kind project organization can overcome the shortcoming of flat static thrust plate, but this design proposal is to open the V-type through hole on complete ball, not only difficulty of processing is big, and its manufacture cost height, and rating curve is not easy to reach perfect condition, therefore is difficult to adapt to the actual demand of building automatic controlization.
Summary of the invention
In order to overcome the shortcoming of the existing flat thrust plate of electric ball valve, the invention provides electric ball valve thrust plate and assembly method.This thrust plate is spherical, by assembling with spool, both is integrally combined, and solves the technical problem that thrust plate assembled and met the rating curve needs.
The scheme that technical solution problem of the present invention is adopted:
Port plate structure: thrust plate is a spherical structure, has V-shaped part on the thrust plate of spherical structure, and thrust plate is assemblied in the spool, and spool is installed in the valve body by valve seat, and valve rod is connected with spool, constitutes electric ball valve.
The assembly method of thrust plate: utilize the interference fit principle of axis hole, the pressure head by press machine and customization is pressed into thrust plate in the spool, and spool and thrust plate are become one.
Good effect owing to be pressed into thrust plate in the spool of electric ball valve, can make spool and thrust plate be combined into one, adapts to the needs of electric ball valve rating curve.And have easy to manufacture, easy to assembly, overall cost is low, the Flow-rate adjustment advantage of high precision.Suiting to make electric ball valve in industrial fluidised form control field uses with regulating in the electric ball valve flow.

Among the figure, 1. electric ball valve, 2. valve rod, 3. valve body, 4. valve seat, 5. spool, 6. thrust plate, 6.1.V shape mouth.
Embodiment
Port plate structure: thrust plate 6 is a spherical structure, has V-shaped part 6.1 on the thrust plate of spherical structure, and thrust plate is assemblied in the spool 5, and spool is installed in the valve body 3 by valve seat 4, and valve rod 2 is connected with spool, constitutes electric ball valve 1.
The assembly method of thrust plate: utilize the interference fit principle of axis hole, the pressure head by press machine and customization is pressed into thrust plate in the spool, and spool and thrust plate are become one.
Thrust plate and spool assembling back cylindrical is concentric, and the radius of thrust plate is less than the radius of spool, so the periphery of thrust plate is lower than the spool periphery.In the spool working stroke, thrust plate can not interfered with other component, and can realize the effect of dynamic adjustments flow.
Thrust plate is the dynamic thrust plate of assembling type, and promptly thrust plate can be assembled in the spool, in the electric ball valve using process, can keep dynamic fit with spool, realizes the flow of dynamic adjustments liquid or gas.
Characteristics of the present invention
1, product degree of regulation height.
Because the structural type that the present invention adopts spool to be crimped on thrust plate has not had spatial joint clearance between spool and the thrust plate, both fit together, and have improved the accuracy of rating curve.And make thrust plate in entire work process, present dynamic operation, overcome traditional actionless shortcoming of flat thrust plate, therefore can improve electric ball valve and transfer the stream precision, therefore have the stream of accent advantage of high precision.
2, easy to manufacture, assembling is easy, cost is low.
Because structure of the present invention is simple relatively, assembling is easy, and spool and thrust plate are assembled into one.Therefore has advantage easy to manufacture, that assembling is easy and cost is low.
3, versatility is good.
According to the characteristic working curve requirement of electric ball valve, thrust plate and spool are adapted, so versatility is good.
The present invention assembles thrust plate in spool can make thrust plate rotate along with valve core rotation.What thrust plate adopted is the V-type spherical structure, and the processing cost that can save the ball core has embodied the advantage of assembling.Not only save assembly space, can reduce the assembling expenditure of time again.
