Abstract
The invention discloses anadjustable timing pneumatic valve, which comprises a valve body, an inner rotor, a mounting seat and an adjusting nut, wherein the inner rotor is inserted into the valve body from one side of the valve body; the valve body is provided with an outlet; the inner rotor is provided with an air supply port; the connection degree between the outlet and the air supply port changes when the inner rotor rotates in the valve body or the inner rotor and the valve body have axial relative motion, or the outlet and the air supply port are switched between connection and disconnection; a lead screw is arranged on the other side of the valve body and is inserted into the mounting seat; and the adjusting nut is screwed on the lead screw. The pneumatic valve has the advantages of simple structure, convenience in operation, flexibility in adjustment, capabilities of being made into different specifications as required and supplying air of different flows to different numbers of pipelines, few parts, easiness and convenience in machining, low cost and high repeated utilization rate.
Description
Technical field
The present invention relates to a kind of adjustable timing pneumatic valve.
Background technique
For pneumatic system, some element requires regularly, quantitative air feed, to reach the purpose of carrying out specific action.At present, Pneumatic butterfly valve commonly used or pneumatic ball valve come the supply and the cut-out of control gaseous on the market, complex structure, and function singleness, it adjusts underaction, and cost is higher.
Summary of the invention
Technological scheme of the present invention is following:
A kind of adjustable timing pneumatic valve comprises valve body, internal rotor, fitting seat and adjustment nut; Said internal rotor is plugged in the valve body from a side of valve body; Valve body is provided with outlet; Internal rotor is provided with air supply opening; When having axial relative movement along with internal rotor rotation or internal rotor and valve body in valve body, the conducting degree changes thereupon between outlet and the air supply opening, or outlet and air supply opening conducting and non-conduction between switching; The opposite side of valve body is a screw mandrel, and screw mandrel is inserted in the fitting seat, and adjustment nut spinning is on screw mandrel.
Described outlet is the interface of radially giving vent to anger, and exports to a plurality of; Said valve body upper edge is axially arranged with scale.
Said fitting seat top and bottom are equipped with the bolt hole that is used for fixing fitting seat.
Beneficial effect
A kind of adjustable timing pneumatic valve of the present invention adopts valve body and internal rotor is carried out a plurality of Interface design, and on valve body reference mark value vertically; Through the adjustment nut; Valve body carries out axial displacement, and internal rotor is rotated in valve body, the corresponding change of conducting degree between feasible outlet and the air supply opening; Realize timing, quantitative air feed, safe and reliable; This pneumatic valve configurations is simple, and is easy to operate, and adjustment flexibly; Can make different size as required, realize gas the pipeline supply different flow of varying number; Number of spare parts is few, processes easyly, with low cost, and recycling rate of waterused is high.

Embodiment
In conjunction with accompanying drawing the present invention is further specified, its detailed process is following:
Be illustrated in figure 1 as adjustable timing pneumatic valve, comprise valve body 1, internal rotor 2, fitting seat 3, adjustment nut 4, adjustment screw thread 5, scale 6 and bolt hole 7; Wherein, 2 internal rotors can be relative 1 valve body rotate, 3 interfaces of radially giving vent to anger of peripheral processing as shown in the figurely are respectively first outlet, 8, second outlet the 9 and the 3rd outlet 10, its interface radius is R, valve body one end is processed with adjustment screw thread 5 and scale 6; 2 internal rotor left ends connect air inlet, and the other end is offered the radially air supply opening identical with valve body air outlet quantity, to realize regularly air feed; Have bolt hole 7 on 3 fitting seats, be installed on valve body on the miscellaneous equipment through bolt; 4 are the adjustment nut, with the axial position of screw-thread fit on valve body adjustment valve body, reach the purpose of control gaseous flow.
Valve block internal diameter is D (mm); The air feed hole count is i (being uniformly distributed with); The valve body rotating speed is n (rpm), then adjacent air vent air feed be blanking time (S) for
same air vent air feed blanking time for (S) is
Shown in Figure 2 is broken away view, is illustrated as internal rotor air vent and the corresponding complete on-state in valve body air outlet.Use this pneumatic valve to carry out air feed, behind the arrival certain hour, valve body is moved axially, make that the communication aperture size between internal rotor air supply opening and the valve body air outlet changes, thereby change ventilation flow rate.
Shown in Figure 3 is the lucky its unaccessed state of air supply opening and air outlet, and at this moment, this air outlet is a dissengaged positions, displacement X=0 between order air supply opening this moment and the air outlet.
Shown in Figure 4 for air supply opening and air outlet are the part on-state, valve body moves axially that displacement is X between air supply opening and the air outlet, and at this moment, this air outlet is in the air feed state of certain flow.
After moving axially, circulation area is the dash area among Fig. 5, and circulation area S satisfies following formula:
S=α R
2-R
2Sin α, wherein,
X is axial displacement;
Radius R=5mm when the hole, the relation of circulation area and axial displacement is as shown in Figure 6 so;
Relation is as shown in Figure 7 between its circulation coefficient and the axial displacement; Said circulation coefficient=S/ π R
2
Can find out that from Fig. 6 and Fig. 7 move axially and the gas flow of valve body are linear approximate relationship, this pneumatic valve can play the flow of gas comparatively precisely and regulate.
