Embodiment
As shown in Figure 1 and Figure 2, for the guiding valve on mud pulse generator, comprising: guiding valve shell 1, guiding valve oil outlet 2, spring 3, guiding valve plunger 4 and guiding valve oil-Absorbing nozzle 5; Guiding valve oil nozzle 2 is installed in one end of guiding valve shell 1, the other end is installed guiding valve oil-Absorbing nozzle 5, and guiding valve plunger 4 is arranged in guiding valve shell 1, between guiding valve plunger 4 and guiding valve oil outlet 2, is provided with spring 3.
The cylindrical body that guiding valve shell 1 is hollow, cylindrical outer surface is provided with four oil outlets, and four oil outlets are positioned at the same plane perpendicular to cylinder axis, and along cylindrical circumferentially uniform, the position of four oil outlets calculative determination as required; The internal surface of guiding valve shell 1 is processed with three step holes, and wherein the step hole in neutral position is the place that guiding valve shell 1 and guiding valve plunger 4 form sliding movement pair, and guiding valve plunger 4 can to-and-fro motion in this step hole, makes guiding valve in opening and closing position; The step hole at two ends forms interference fit with guiding valve oil outlet 2, guiding valve oil-Absorbing nozzle 5 respectively, plays the effect of two sealing.
Guiding valve oil outlet 2 is arranged on guiding valve shell 1 by interference fit, and guiding valve oil outlet 2 is provided with endoporus, two O circle seal grooves, and endoporus is the control channel that guiding valve leaves valve and pass valve, in the time that this endoporus is blocked, guiding valve is in close valve state, and as shown in Figure 1, fluid flows out without guiding valve; In the time that this endoporus is opened, guiding valve is in open mode, and as shown in Figure 2, most of fluid is through four oil outlets on guiding valve shell 1, and a fraction of fluid passes through to flow out from guiding valve oil outlet 2 endoporus after the micro hole on guiding valve plunger 4; Guiding valve oil outlet 2 is provided with spring seat with one end that guiding valve shell 1 is connected.
Spring 3 adopts standard piece, is arranged on guiding valve shell 1 inside, and its effect is to make guiding valve plunger 4 return to pass valve position; One end of spring 3 is pressed on guiding valve plunger 4, and one end is pressed on guiding valve oil outlet 2, and when the micro hole on guiding valve plunger 4 does not have hydraulic oil to pass through, guiding valve is in close valve state.When micro hole on guiding valve plunger 4 has hydraulic oil to pass through, because micro hole convection cell has damping function, make guiding valve plunger 4 the right and lefts form pressure reduction, this pressure reduction of pressure that the pressure on guiding valve plunger 4 the right is greater than the left side will promote guiding valve Compress Spring, in the time that guiding valve moves to certain position, four oil outlets on guiding valve shell 1 are opened, and guiding valve forms new balance under the pressure of pressure reduction and spring.
Guiding valve plunger 4 is arranged in guiding valve shell 4, guiding valve plunger 4 is provided with aperture along axial direction, this aperture convection cell has damping function, make guiding valve plunger 4 the right and lefts form pressure reduction, this pressure reduction of pressure that the pressure on guiding valve plunger 4 the right is greater than the left side will promote guiding valve Compress Spring, and this micro hole can play the effect of the pressure at balance slide valve plunger two; The outer surface of guiding valve plunger 4 and guiding valve shell 1 form Spielpassung, and guiding valve plunger 4 can be free to slide in guiding valve shell 1; When guiding valve is in the time leaving valve state, due to the damping function of micro hole, make guiding valve the right and left have pressure difference, guiding valve plunger 4 slides left at the effect lower compression spring of fluid pressure, move to the right part of guiding valve plunger 4 when concordant with four oil outlets on guiding valve shell 1, the bypass of guiding valve is opened, and four oil outlets of most of fluid from guiding valve shell flow out, and sub-fraction fluid flows out from guiding valve oil outlet 2 after by the micro hole on guiding valve plunger 4; When guiding valve is during in close valve state, the draining passage of guiding valve oil outlet 2 is closed, and due to the existence of micro hole, makes guiding valve plunger 4 left and right pressure at two ends balances, guiding valve plunger 4 slides to the right under the effect of spring, and four oil outlets on guiding valve shell 1 are stopped up by guiding valve plunger 4.
Guiding valve oil-Absorbing nozzle 5 is arranged on guiding valve shell 1 by cooperation, and O RunddichtringO groove and one section of external cylindrical surface are set on guiding valve oil-Absorbing nozzle 5, and the inner cylindrical surface on this external cylindrical surface and guiding valve shell 1 forms interference fit, plays sealing and positioning action.
On this guiding valve, there are two fluid passages: bypass path and micro hole path, guiding valve plunger 4 has two working positions in guiding valve shell 1, drive valve position and close valve position, in the time that the fluid flow pass on guiding valve oil outlet 2 is opened, fluid flows into 2 li of guiding valve oil outlets by the micro hole on guiding valve plunger 4, guiding valve is in open mode, in the time of micro hole path blockade; In the time that the fluid flow pass on guiding valve oil outlet 2 is closed, the micro hole on guiding valve plunger 4 plays the effect of balance both sides pressure, and guiding valve plunger 4 moves right under the active force of spring, makes guiding valve in closed condition.
Guiding valve of the present invention has two working positions, in accompanying drawing 1, guiding valve plunger 4 is in closed condition, four oil outlets on guiding valve shell 1 should not have fluid to flow out, guiding valve oil outlet 2 is also in pent state, 2 li of guiding valve oil outlets should not have hydraulic oil to flow out, and now the pressure at two ends of guiding valve plunger 4 is in state of equilibrium.In accompanying drawing 3, guiding valve, in opening valve state, has fluid to flow out in four oil outlets on guiding valve shell 1, and guiding valve oil outlet 2 also has fluid to flow out.After guiding valve oil outlet 2 is opened, now due to the damping function of micro hole on guiding valve plunger 4, make guiding valve plunger 4 act on two ends and have pressure reduction, the pressure of guiding valve plunger 4 right-hand members is greater than the pressure of left end, the effect that guiding valve plunger 4 is under pressure is moved to guiding valve oil outlet 2 directions, until two ends stressed reaches new state of equilibrium.The big or small length of guiding valve can change accordingly according to technological requirement.
