Background technique
When centrifugal pump during in critical low-load; need a reliable recirculating system to prevent overheated. and a lot of such system is to consist of several difference in functionality valves; need higher design, installation and maintenance expenses, and the new pump Protective valve can be accurately and is carried out independently the various functions in circulation loop.
Most conventional pumps Protective valve generally adopts lever principle: when the medium following current, flap is opened automatically, and flap drives the fork motion, and fork drives the loose piece action again, closes bypass; When medium counter flow, flap is closed automatically, and flap drives the fork motion, and fork drives the loose piece action again, opens bypass, and the water that pump is got is discharged and again flowed back in feed tank from bypass.
Owing to adopting lever drive: flap drives the fork motion, and fork drives the loose piece action again, complex structure, and in the middle of the process of interlock, easy jam, performance is poor; Loose piece, owing to not being subject to the power of enforcement sealing, can produce vibration and noise owing to being not closed completely usually in addition, causes a large amount of energy wastes.
Thus, must adopt new design proposal to improve running environment is necessary.
The model utility content
The purpose of this utility model be provide a kind of in order to solve above-mentioned the deficiencies in the prior art and operate steadily, without a kind of new pump Protective valve of jam, installation and convenient disassembly.
To achieve these goals, a kind of new pump Protective valve that the utility model is designed, comprise valve body, described valve body comprises intake pipe, outlet conduit and bypass duct, intake pipe, outlet conduit is positioned at same level, bypass duct is positioned at the adjacent side of intake pipe, it is characterized in that: be provided with main valve clack and secondary flap in described valve body, main valve clack and secondary flap are coaxial configuration, auxiliary-seat one end is positioned at the inner chamber concourse of bypass duct and valve body, the secondary flap the other end is rigidly connected by screw thread and main valve clack, positioning wheel is installed on outlet conduit, the axostylus axostyle be fixed with positioning wheel is installed on positioning wheel, the axle head of axostylus axostyle is placed in the valve body chamber, main valve clack is provided with the positioning shaft hole matched with the axle head of axostylus axostyle, also be provided with elastic component in positioning shaft hole, the internal surface of described elastic component one end and positioning shaft hole is conflicted, the outer surface of the other end and axle head is conflicted, the length range straight line motion that described main valve clack is flexible at described elastic component, also be provided with alternatively distributed runner aperture on described secondary flap, valve body is provided with sealing surface in chamber, sealing surface is closed fluid and is entered in the runner aperture.
Preferably, the periphery ring of described main valve clack is provided with the inner groovy with radian.
Preferably, intake pipe, outlet conduit and bypass duct are on same axis.
Preferably, on described bypass duct, the mazy type restricting orifice is installed.
Preferably, described elastic component is the spring part.
The new pump Protective valve that the utility model obtains; adopt major-minor flap coaxial configuration; flexible movements; without jam, the periphery ring of main valve clack also is provided with the inner groovy with certain radian and adopts the special flow passage structure, utilizes the self-powering type action principle; thrust increases; in bypass duct setting and body, intake pipe, outlet conduit and internal bypass duct bottom, on same axis, are convenient to processing with one heart.Be processed with the twice aperture on secondary flap axle, aperture is alternately distributed, and bypass flow flows out from aperture, and because aperture has the function of noise control step-down, therefore, this valve operates steadily, can vibration-generating and large noise, belong to the high-quality environment-friendly products.
