The specific embodiment
To combine accompanying drawing that the utility model embodiment is done to describe in detail further below.
The colliery of the utility model can't harm dropping valve with adjustable high-voltage, the specific embodiment that it is preferable:
Comprise valve body, the right part of said body cavity is provided with guide pin bushing, sliding sleeve, intermediate sleeve successively, is provided with valve rod in said guide pin bushing, sliding sleeve and the intermediate sleeve; The right-hand member of said valve body is provided with nipple; And on nipple, be provided with inlet, and the sidewall of said valve body right part is provided with working hole and liquid return hole, and the left part of said body cavity is provided with spring; The left end of said valve body is provided with the pressure regulation swivel nut, and the right-hand member of said spring is against on the said valve rod through spring base;
Be provided with left chamber and right chamber in the said valve rod, the sidewall in said left chamber is provided with the first liquid mouth and the second liquid mouth, and the sidewall in said right chamber is provided with the 3rd liquid mouth and the 4th liquid mouth, is provided with annular chamber between said sliding sleeve and the said valve rod;
When said valve rod was in right position, the said first liquid mouth communicated with working hole, and said second liquid mouth and the 3rd liquid mouth communicate through said annular chamber, said the 4th liquid mouth sealing;
When said valve rod was in position, a left side, the said first liquid mouth communicated with working hole, and said second liquid mouth and the 3rd liquid mouth break off, and said the 4th liquid mouth communicates with liquid return hole.
Said valve body is threaded with said pressure regulation swivel nut.
The utility model is according to the operating pressure needs of down-hole various device, uses same pumping plant that the output of two or several different pressures can be provided simultaneously.In addition, when instability appears in pumping plant pressure, in hydraulic system, embed this dropping valve and can obtain a stable lower pressure, keep the stability of system.Can be applied to the hyperbaric environment under the coal mine, the step-down scope can not produce any pressure loss to regulating also arbitrarily between the pumping plant pressure of down-hole basically zero, and medium is an emulsion.
The operating principle of the utility model is following:
Like Fig. 1, shown in Figure 2, when the highly pressurised liquid that comes out from pumping plant when inlet P gets in this dropping valve, inlet P communicates with working hole A through the 3rd liquid mouth 13, annular chamber 10, the second liquid mouth 12, the first liquid mouth 11 successively, simultaneously, spring 3 is pressurizeed; When the pressure at working hole A place was higher than setting, spring 3 was compressed, and promoted valve rod 5 and moved to left; Valve rod 5 breaks off the passage between inlet P and the working hole A through moving to left; Make working hole A place keep constant setting, be communicated with inlet P and liquid return hole T simultaneously, guarantee the smoothness of hydraulic system.
In concrete the application, the user can set up arbitrarily in its preset range the operating pressure of this dropping valve according to the safety in production needs of oneself, has higher flexibility.Because the feedback ratio that there is not output pressure in this utility model is, but directly by the precompression control of spring, so the pressure loss of the utility model is zero basically.Next is essential and wants same pumping plant can be applied to coal mine, and the occasion of different output pressures is that applying unit is saved power source, reduces investment, and range of application and prospect are boundless; Use flexibly, easy to maintenance.According to the difference of its working pressure, can in its predetermined range of regulation, set up arbitrarily, reserved bigger development space to applying unit.
The above; Be merely the preferable specific embodiment of the utility model; But the protection domain of the utility model is not limited thereto; Any technician who is familiar with the present technique field is in the technical scope that the utility model discloses, and the variation that can expect easily or replacement all should be encompassed within the protection domain of the utility model.Therefore, the protection domain of the utility model should be as the criterion with the protection domain of claims.
