Description of drawings:
Fig. 1 is a generalized section of the present invention;
Fig. 2 is a perspective view of the present invention;
Fig. 3 is a scheme of installation of the present invention.
Embodiment:
With specific embodiment the present invention is further described below, referring to Fig. 1-3:
The high-pressure plunger pump pressure-regulating system of band easy starting function is made up of voltage-regulating system and easy starter gate valve, is provided with the closable easy starter gate valve of setting pressure between the inhalant region 14 of described voltage-regulating system and backwater zone 9.
Above-mentioned easy starter gate valve is: on the pipeline that is communicated with in the inhalant region 14 of voltage-regulating system and backwater zone 9, easily the elastic force of the spring 10 of starter gate valve makes the position of spool 12 away from the pipeline conducting of valve seat 11.
Above-mentioned spool 12 is steel balls.
The pipeline that the inhalant region 14 of above-mentioned voltage-regulating system and backwater zone 9 is communicated with: be the auxiliary hole of setting up between voltage-regulating system inhalant region 14 and backwater zone 9, the collar extension of auxiliary hole is provided with and stops up 13, and obstruction 13 is connected with valve seal.
The valve seat 11 of above-mentioned easy starter gate valve is the step hole on the pipeline that is communicated with of the inhalant region 14 of voltage-regulating system and backwater zone 9.
Above-mentioned voltage-regulating system includes upper valve body 15 and following valve body 8, upper valve body 15 is arranged on down the top of valve body 8, the bottom of following valve body 8 is backwater zone 9, be formed with vertical pipeline at following valve body 8 with upper valve body 15, vertically in the pipeline backflow chamber is arranged, and vertically be disposed with pressure regulator valve, pressure adjusting spring pad 4, pressure adjusting spring 3 from bottom to up in the pipeline, pressure adjusting spring 3 also is arranged in the adjusting pressuring handle 1 by pressure regulation cap 2, adjusting pressuring handle 1 is spirally connected with upper valve body 15, and pressure regulator valve mainly includes: pressuring adjusting valve base 17, pressure regulator valve 18 and pressure regulation valve rod 16; Be provided with outlet valve 7 between inhalant region 14 and exhalant region 6, the pipeline of outlet valve 7 is provided with and opens valve water channel 5 and be communicated with the backflow chamber.
The present invention is integrated in original voltage-regulating system of pump and easy starting function on the assembly, original voltage-regulating system is brought into play original pressure regulation, is crossed outside pressurized overflow and the pass rifle unloading function, add easy start-up function simultaneously, voltage-regulating system and easy starter gate valve shared pressure regulation body, inlet pipeline and backwater channel.
When pump does not start, easily the steel ball 12 in the starter gate valve under spring 10 effects always away from the step hole on the pipeline, be that easy starter gate valve remains on open mode, when starting with pump, pump medium flow directly is back to inhalant region from easy starter gate valve, can not form pressure in the pump, when the startup rotating speed of pump reaches certain value (this value assert greater than rotating speed or petrol engine idling after the motor maximum current), when the flow of pump medium increases certain value, medium promotes the active force that steel ball 12 overcomes spring 10, shutoff is on step hole, easily starter gate valve cuts out, medium can only as exhalant region 6 external pipeline loads, then just form high pressure through voltage-regulating system to exhalant region 6 in the pump in the pump.Pressure regulating valve 18 is sealing under the effect of pressure adjusting spring 3 and between the pressuring adjusting valve base 17, when the pressure medium in the pump is too high, be that the working pressure of medium in the pump is when surpassing rated working pressure, high-pressure medium is by entering in the voltage-regulating system, because pressure medium is higher, high-pressure medium backs down outlet valve 7, high-pressure medium enters to enter by outlet valve 7 and opens valve water channel 5, high-pressure medium enters the backflow chamber from opening valve water channel 5, thereby high-pressure medium backs down pressure regulation valve rod 16, driving pressure regulating valve 18 opens, making between pressuring adjusting valve base 17 and the pressure regulating valve 18 was that the Xiao Xu that becomes of sealing state opens originally, and high-pressure medium just enters inhalant region by the gap between pressuring adjusting valve base 17 and the pressure regulating valve 18, thereby the liquid of overpressure is discharged, the pump internal pressure is descended, to guarantee the Security of pump work.
Otherwise when the pressure in the pump diminished, the gap smaller between pressuring adjusting valve base 17 and the pressure regulating valve 18 reduced high-pressure medium by the gap overflow between pressuring adjusting valve base 17 and the pressure regulating valve 18, around the pump internal pressure is stabilized in rated pressure.
When the equipment that is connected on exhalant region 6 is closed suddenly when damming, when promptly closing rifle, the pump internal pressure raises suddenly, and pressuring adjusting valve base 17 becomes big with pressure regulating valve 18 gaps simultaneously, simultaneously also because of no current effect, outlet valve 7 is closed, and high-pressure medium promotes 16 risings of pressure regulation valve rod by opening in the valve water channel 5, drive pressure regulating valve 18, gap between pressure regulating valve 18 and the pressuring adjusting valve base 17 is opened fully, make the medium perfect overflow in the pump, the pump internal pressure is reduced to intake pressure, reaches the purpose of automatic deloading.
When being connected on the opening of device of exhalant region 6, when promptly shooting, high-pressure medium flows away by exhalant region 6, pressure regulating valve 18 descends and resets under the effect of pressure adjusting spring 3, again sealing between pressure regulating valve 18 and the pressuring adjusting valve base 17, no longer overflow of medium in the pump, pump enters normal working.
The foregoing description is one of preferred embodiment of the present invention only, is not to limit practical range of the present invention with this, so: all equivalences of doing according to shape of the present invention, structure, principle change, and all should be covered by within protection scope of the present invention.
