Embodiment

With reference to figures 1 through 2, will be described in detail the utility model below.

The integral intelligent mortor operated valve that specific embodiment 1 provides function combinations such as a kind of bigbore collection automatic flow balance, water filtration, motor switch butterfly valve, dynamic measurement and maintenance to form, comprise the mortor operated valve part of forming by electric actuator 3 and electric butterfly valve 2, connect a front valve shell part at mortor operated valve part inlet side.Front valve shell partly comprises the front valve shell stream tube 1 of a Y shape, in the Y shape projection of front valve shell stream tube 1, water filtering barrel 7, flow control urceolus 9, highi degree of accuracy spring 10 and flow control spool 11 are installed from outside to inside successively, flow control urceolus 9 front ends have the hole that is suitable for flow control spool 11, and flow control spool 11 can slide in the hole; Flow control urceolus 9 front edges are connected with front valve shell stream tube 1 inwall, and the centre has an O RunddichtringO 12 to be used for sealing; Maintenance dish 6 is connected the fixing internal parts with the Y shape projection of front valve shell stream tube 1.

Flow control spool 11 is a hollow, and the top has a through hole, has the current through hole that two or more specialized designs have special shape on the wall, i.e. the arc-shaped curved surface through hole that amplifies gradually along fluid flow direction.Stainless steel highi degree of accuracy spring 10 is housed between flow control spool 11 and the flow control urceolus 9, and flow control spool 11 can move along water (flow) direction.When coming water pressure to raise, flow control spool 11 promotes spring 10 compressions, and the flow area of spool current through hole reduces; When coming water pressure to reduce, flow control spool 11 extends because of spring 10 active forces, and the flow area of spool current through hole increases, thus the automatic control function of realization valve flow.

Water filtering barrel 7 also is a hollow, has the little filtering hole of a plurality of equally distributed circles on the wall.Water filtering barrel 7 is connected in fastening valve port sleeve 8 with flow control urceolus 9.

Fastening valve port sleeve 8, flow control urceolus 9, highi degree of accuracy spring 10, flow control spool 11 have constituted the automatic flow Equilibrator jointly.

Also have a measurement to chew 13 on the front valve shell stream tube 1.

Also comprise a rear valve body part, rear valve body partly is the rear valve body stream tube 4 of a straight shape, also has a measurement to chew 5 on it.

Only the maintenance dish need be unloaded, the rectification smart valve all can overhaul and safeguard, and is very convenient.Even when operation, also can check qualitatively or quantitative dynamic test by measuring hole.

The work basic principle of automatic flow Equilibrator is: flow action makes flow control spool 11 and flow control urceolus 9 that relative displacement s be arranged on flow control spool 11.Form pressure drop Δ P simultaneously in flow control spool 11 both sides.

Pass through flow (Q) representation of valve this moment:

$Q=\mathrm{Cv}\×\sqrt{\mathrm{\ΔP}}$

Cv is the flow coefficient of valve

Flow control spool 11 is when action, and the effluent hole area makes it that different negotiabilities be arranged changing, and Cv is the function of displacement s, its mathematic(al) representation:

Cv＝Cv(s)

Flow control spool 11 two ends pressure drop Δ P act on the power and the spring force F balance of spool 11, and we adopt the highi degree of accuracy spring with linear deformation characteristic, and spring force F is the linear function of displacement s (being amount of spring compression), and Δ P also is the function of displacement s.

Suppose the top area of contour Ap (belonging to constant) of flow control spool 11, preliminary examination spring force F0, K are the Young's modulus of spring, and they have following relation:

$\text{Q=Cv}\left(s\right)\×\sqrt{\mathrm{\ΔP}\left(s\right)}$

F＝K×s+F ₀＝ΔP(s)×Ap

Effluent hole flow-passing surface belongs to the perforate on the cylndrical surface, so effluent hole flow-passing surface area A can be passed through the FAST plot cartographic represenation of area:

A＝A(s)

According to the model simplification of fluid mechanics equation of continuity and momentum equation, when fluid is flowed through flow control spool,, obtain relation by the simultaneous solution set of equation in order to keep the constant of automatic flow:

A(s)＝C ₁×(F ₀+K×s+C ₂) ^-1/2

Find the solution four perforate symmetrical curve g (z) that can obtain FAST plot by first order derivative, wherein one is expressed as follows:

$g\left(z\right)=\mathrm{<figure-callout\; id="1"\; label="C"\; filenames="Y20052010047000081.png"\; state="\{\{state\}\}">C</figure-callout>}1\&times;K\&times;\frac{{(F_0+K\&times;z+C_2)}^{-3/2}}{8}$

C wherein ₁, C ₂, F ₀Be constant, K is the Young's modulus of spring, utilizes laboratory data to demarcate during by valve modularization flow and obtains, and concrete data can be searched product modularization sample.The perforate of this area of passage is easy to realize on the digital control processing machine.The utility model is exactly a highi degree of accuracy balance of utilizing this mathematical relationship control flow rate.

At last, it is also to be noted that what more than enumerate only is specific embodiment of the utility model.Obviously, the utility model is not limited to above embodiment, and many distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of the utility model all should be thought protection domain of the present utility model.
