Abstract
An internal and external force combination control valve belongs to a control valve. A spur track of a prior art self-operated control valve is jammed easily and a traditional control valve has a complex executive process and costly cost. What the utility model wants to solve is to conquer the above two deficiencies. The utility model is composed of a entrance cavity and a control cavity, the internal structure of the entrance cavity being the same as the self-operated control valve of the prior art and the control cavity being separated with the entrance cavity. A gas source pressure outside of the system or liquor pressure being used to control the pressure of the control cavity in order to realize the on-off and control of the valve, the utility model is applicable to all the situations in which an average control valve can be used. The utility model overcomes the disadvantage of jam for the self-operated control valve spur track and the disadvantage of the complex executive process and costly cost for the traditional control valve, thereby realizing a perfect combination of advantages of the above two control valves.
Description
Technical field
The utility model belongs to a kind of control valve, is specifically related to a kind of interior external force in conjunction with control valve.
Background technique
Number of patent application is 200520112453X, 2005100804995 and 2005200250427 control valves of introducing of relying on oneself are to establish a barrier film between valve body and the valve gap, valve is divided into three cavitys: entrance cavity, outlet plenum and control chamber, secret tunnel and little control valve are arranged between entrance cavity and control chamber, secret tunnel and little control valve are also arranged between outlet plenum and control chamber, change the pressure of control chamber with the switch of two above-mentioned little control valves, thereby realize opening of control valve main body, close, transfer, lock, control, its shortcoming is that described secret tunnel and little control valve are easily stopped up by the solid impurity of fluid in the system, when stopping up, the function of this valve just can't realize.
Commercially available control valve is made up of valve body and actuator's two-part, and the valve rod on the described valve body is connected with the connecting rod of actuator by behind the packing box seal.Because the existence of stuffing box, resistance is very big during valve switch, and actuator must export very big push-pull effort just can make valve open and close, control.That described actuator has is pneumatic, surge and electronic three kinds.Pneumatic diaphragn actuating mechanism is made of last membrane cover, following membrane cover, film, support, spring, adjusting element, connecting rod etc.; The film that surges is carried out, and is roughly identical with air bladder mechanism.The adjusting of air pressure or hydraulic pressure has one of electromagnetic valve to overlap mechanism greatly again.Motor drive mechanism can be divided into motor-operated control valve, solenoid valve, electronic governor impeller and electric power regulator and annex thereof.Common drawback electronic, pneumatic and liquid actuator is the process complexity, and parts are various, easily go wrong, and involve great expense.
Summary of the invention
The purpose of this utility model is to develop a kind of interior external force reliable, with low cost in conjunction with control valve.
The valve mechanism that control valve of the present utility model and 200520112453X introduce is basic identical, it is characterized in that the secret tunnel with original entrance cavity and control chamber valve changes the secret tunnel of external gas potential source and hydraulic power into, changes the secret tunnel between outlet plenum and control chamber into atmosphere emptying secret tunnel.Keep two little control valves on the former secret tunnel.By the switch of described two little control valves, the pressure of control control chamber, this pressure are during more than or equal to valve inlet pressure, and main valve closes; When this pressure equated with atmospheric pressure, main valve was opened; This pressure circle is in state of a control between inlet pressure and outlet pressure the time.
External force is in conjunction with control valve in a kind of, constitute by valve gap, spring, barrier film pressing plate, barrier film, valve rod, valve disc, sealing gasket, valve body, sealing gasket pressing plate, a side that it is characterized in that valve gap has gas pressure source or hydraulic power inlet secret tunnel, on this secret tunnel, control valve is arranged, at the opposite side of valve gap the secret tunnel in logical atmosphere or pass-out oral cavity is arranged, control valve is arranged on secret tunnel.
The conspicuous advantage of the utility model valve is as follows:
1. compare with traditional control valve of do-part with being divided into valve body part, control chamber fuses with the turnover oral cavity, open and close, transfer laborsaving, can run, drip, leak.
2. compare with commercially available self force type control valve, solved that the branch road secret tunnel stops up and the fundamental issue that can not move.Because the external source of the gas or the pressure of hydraulic power can improve as required, so that diaphragm area and valve port area ratio require is not tight, under general situation, all can effectively regulate and control, this is that commercially available self-powering type control valve is difficult to accomplish.
3. compare with traditional control valve, cost reduces greatly, easily makes, and is difficult for producing fault.
Description of drawings
Fig. 1 is a valve port periphery guiding control valve.
Fig. 2 is that spindle guide is to control valve.
As shown in the figure, 1 is valve gap, and 2 is spring, 3 is the barrier film pressing plate, and 4 is barrier film, and 5 is valve rod, 6 is valve disc, and 7 is sealing gasket, and 8 is valve body, 9 for having the sealing gasket pressing plate of guide fin, and 10 is gas pressure source or hydraulic power inlet secret tunnel, and 11 is inlet pressure source control valve, 12 are outlet source of the gas pressure controlled valve, and 13 are logical atmosphere outlet secret tunnel, and 14 are control liquid outlet secret tunnel, 15 for to be used to regulate the special-shaped pressing plate of flow curve character, and 16 is end guide sleeve.
Embodiment
Embodiment 1
As shown in Figure 1, it is by valve gap 1, spring 2, barrier film pressing plate 3, barrier film 4, valve rod 5, valve disc 6, sealing gasket 7, valve body 8, sealing gasket pressing plate 9 constitutes, and in a side of valve gap 1, is provided with gas pressure source inlet secret tunnel 10, inlet bleed pressure control valve 11 is arranged on this secret tunnel 10,, logical atmosphere outlet secret tunnel 13 is arranged at the opposite side of valve gap 1, outlet source of the gas pressure controlled valve 12 is arranged on it, and described control valve 11 is the porcelain core valve, needle value or solenoid valve; Control valve 13 is porcelain core valve, needle value, solenoid valve, decompression venting valve, holds and press Decompression valves or float valve.
Embodiment 2
As shown in Figure 2, it feeds the process filtered liquid of potential source water or this valve of flowing through on secret tunnel 10, and what be communicated with valve outlet port is not open to atmosphere secret tunnel 13, but leads to the secret tunnel 14 of main valve body outlet.What replace sealing clamp 9 is the special-shaped pressing plate 15 that is used to regulate the flow curve characteristic, and other are with embodiment 1.
