Fig. 2 is that the utility model pressure scale and pressure pointer coordinate schematic diagram.
Fig. 3 is the stereochemical structure exploded view of mounting pipe of the present utility model, spring sheet, pressure pointer, regulating hand wheel of pressure.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1, backwater valve seat 1 is arranged on the lower end of mounting pipe 2; The inwall of regulating hand wheel of pressure 3 has internal thread 301, and outside thread 201 is arranged at the top of mounting pipe 2 outer walls, and regulating hand wheel of pressure 3 is together by a threaded connection with mounting pipe 2, and while rotating regulating hand wheel of pressure 3, regulating hand wheel of pressure 3 relatively mounting pipe 2 moves up and down; The upper end portion of the second pressure regulation bar 4 is fixedly mounted on 3 li of regulating hand wheel of pressures, when manufacturing regulating hand wheel of pressure 3, can, by injection moulding mode, the direct injection moulding of the second pressure regulation bar 4 be embedded in to 3 li of regulating hand wheel of pressures; The lower end of the second pressure regulation bar 4 is connected with pressure adjusting spring 5, and the lower end that pressure adjusting spring 5 lower ends connect the first pressure regulation bar 6, the first pressure regulation bars 6 is connected with back-water valve (BWV) 7, and back-water valve (BWV) 7 is against in the backwater import 101 of backwater valve seat 1; While rotating regulating hand wheel of pressure 3, by the transmission of the second pressure regulation bar 4, pressure adjusting spring 5, the first pressure regulation bar 6, can move up and down back-water valve (BWV) 7, regulate the position relationship of back-water valve (BWV) 7 relative backwater imports 101, can produce and close backwater import 101 or the change backwater import 101 backwater big or small effect of intaking; There is through hole at Sealing 8 centers, by through hole, are enclosed within on the first pressure regulation bar 6, and meanwhile, Sealing 8 is arranged on backwater valve seat 1, mainly the backwater in backwater valve seat 1 are played to hermetic barrier effect with the external world.
As shown in Figure 1, 2, 3, pressure scale 11 is marked on the outer wall middle part of regulating hand wheel of pressure 3, the lower end of pressure pointer 9 is arranged on the lower end of mounting pipe 2 by the first screw 10, the middle part bending of pressure pointer 9 is outside, then bending upwards, and upper end is positioned at the outside of regulating hand wheel of pressure 7, the pointer end 901 of pressure pointer 9 approaches with pressure scale 11, rotate regulating hand wheel of pressure 7, the pointer end 901 of pressure pointer 9 can refer to, on corresponding pressure scale 11, demonstrate corresponding force value.
As Fig. 1, shown in 3, spring sheet 12 is arranged in mounting pipe 2 by the second screw 13, the upper end of spring sheet 12 is fixed with a collision bead 14, locating slot 302 is arranged on the inwall of regulating hand wheel of pressure 3, while rotating regulating hand wheel of pressure 3, collision bead 14 can move or be positioned on locating slot 302 at the inwall of regulating hand wheel of pressure 3, be subject to the elastic reaction of spring sheet 12, can there is with locating slot 302 sound clashing in collision bead 14, prompting rotate in place, simultaneously, the pointer end 901 of pressure pointer 9 can refer on corresponding pressure scale 11, demonstrating regulating hand wheel of pressure 3 instantly regulates the force value of plunger pump to be out how many.
When the input power of plunger pump certain, rotate regulating hand wheel of pressure 3, by the control of 7 pairs of backwater water inlets of back-water valve (BWV), between pressure minimum after the maximum pressure that can produce at plunger pump and completely pressure release, regulate, when back-water valve (BWV) 7 cuts out backwater import 101 completely, pressure is maximum, and when opening backwater import 101 completely, pressure is minimum.Adjusting handle 3, when certain rotation amplitude, just has a specific force value, around this principle, and mark pressure scale 11 on the outer wall of adjusting handle 3, and indicate by pressure pointer 9; Simultaneously at the inwall of regulating hand wheel of pressure 3, the position of collision bead 14 contacts arranges a corresponding locating slot 302, while rotating regulating hand wheel of pressure 3 pressure regulation, when collision bead 14, clash into and send prompt tone with this locating slot 302, illustrate that pressure regulates and puts in place; The wedging function of collision bead 14 and locating slot 302, has the effect of location regulating hand wheel of pressure 3, can prevent that regulating hand wheel of pressure 3 from moving, and causes pressure to change.
As shown in Figure 3, further, on regulating hand wheel of pressure 3, the position that is used for being grabbed by hand is designed with arc groove 303, during pressure regulation, can conveniently rotate regulating hand wheel of pressure 3.
