Embodiment
Below in conjunction with accompanying drawing the embodiment of the invention is described in further detail.
Colliery of the present invention can't harm dropping valve with adjustable high-voltage, the embodiment that it is preferable:
Comprise valve body, the right part of described body cavity is provided with guide pin bushing, sliding sleeve, middle cover successively, be provided with valve rod in described guide pin bushing, sliding sleeve and the middle cover, the right-hand member of described valve body is provided with inipple, and be provided with liquid entering hole at inipple, and the sidewall of described valve body right part is provided with working hole and liquid return hole, and the left part of described body cavity is provided with spring, the left end of described valve body is provided with the pressure regulation swivel nut, and the right-hand member of described spring is against on the described valve rod by spring seat;
Be provided with left chamber and right chamber in the described valve rod, the sidewall in described left chamber is provided with the first liquid mouth and the second liquid mouth, and the sidewall in described right chamber is provided with the 3rd liquid mouth and the 4th liquid mouth, is provided with annular chamber between described sliding sleeve and the described valve rod;
When described valve rod was in right position, the described first liquid mouth communicated with working hole, and the described second liquid mouth and the 3rd liquid mouth communicate by described annular chamber, described the 4th liquid mouth sealing;
When described valve rod was in position, a left side, the described first liquid mouth communicated with working hole, and the described second liquid mouth and the 3rd liquid mouth disconnect, and described the 4th liquid mouth communicates with liquid return hole.
Described valve body is threaded with described pressure regulation swivel nut.
The present invention uses same pumping plant that the output of two or several different pressures can be provided simultaneously according to the working pressure needs of down-hole various device.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 substantially zero, and medium is emulsified liquid.
Working principle of the present invention is as follows:
As shown in Figure 1 and Figure 2, when the highly pressurised liquid that comes out from pumping plant was in liquid entering hole P enters this dropping valve, liquid entering hole P communicated with working hole A by the 3rd liquid mouth 13, annular chamber 10, the second liquid mouth 12, the first liquid mouth 11 successively, simultaneously, and to spring 3 pressurizations; When the pressure at working hole A place was higher than setting, spring 3 was compressed, promoted valve rod 5 and moved to left, valve rod 5 disconnects the passage between liquid entering hole P and the working hole A by moving to left, make working hole A place keep constant setting, be communicated with liquid entering hole 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 prespecified range the working 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 delivery pressure in this invention is, but directly by the precompression control of spring, so the pressure loss of the present invention is zero substantially.Next is essential and wants same pumping plant can be applied to coal mine, and the occasion of different delivery pressures is that applying unit is saved power source, reduces investment, and application area 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; only for the preferable embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claims.
