Described pressure regulation stop valve also comprises the overcurrent cover that is arranged on flow-off joint bosom position, and overflow can be made so more stable.
Described high-pressure water outlet is 3, to be separately positioned in the middle part of valve body with high pressure water import at a distance of the position of 90 °, 180 °, 270 °, can to select arbitrarily a use according to mounting point.
Inner peripheral surface, valve pocket lower outer circumferential face and flow-off upper end of joint inner peripheral surface and be equipped with seal ring between flow-off upper end of joint outer peripheral surface and through hole bottom inner peripheral surface in the middle part of described lower portion thereof outer peripheral surface and through hole top inner peripheral surface, valve pocket top outer peripheral surface and through hole.
The reasonable in design of pressure regulation stop valve provided by the invention, compact, and be convenient to regulate and degree of regulation is high.In addition, its flow-off joint adds overcurrent cover, and overflow can be made so more stable.In addition, good sealing effect, so can bear higher pressure than traditional pressure regulation stop valve.
Accompanying drawing explanation
Fig. 1 is pressure regulation stop valve longitudinal sectional structure sectional view provided by the invention.
Fig. 2 be in Fig. 1 A-A to sectional view.
Embodiment
Below in conjunction with the drawings and specific embodiments, pressure regulation stop valve provided by the invention is described in detail.
As shown in Fig. 1-Fig. 2, pressure regulation stop valve provided by the invention comprises valve body 1, valve rod 2, spring 3, valve pocket 4, flow-off joint 5, handle 6 and hand 7; Wherein the center portion of valve body 1 has been formed through an axial hole 8, its underpart peripheral wall is formed with a high pressure water import be connected with high pressure water exhaust port on pump head 9 and at least one high-pressure water outlet 10, and high pressure water import 9 is all connected with through hole 8 with high-pressure water outlet 10; The bottom of handle 6 is inserted in the upper end-hole inside of through hole 8; Hand runs through the middle part of handle 67 levels and arranges; It is inner that the lower end mouth being arranged on through hole 8 on valve body 1 is inserted in one end of flow-off joint 5; Valve pocket 4 is located at the middle and lower part of through hole 8, in the middle part of it, peripheral wall is formed with the perforate 11 corresponding with above-mentioned high pressure water import 9 and high-pressure water outlet 10, and lower end part is in flow-off joint 5 upper inner; Valve rod 2 is nail shape structure, and be located at the inside of through hole 8, its head contacts with the lower end of handle 6, and bar portion is then arranged on middle and upper part in valve pocket 4; Spring 3 is enclosed within the bar portion outer surface of the valve rod 2 between the head and valve pocket 4 upper end of valve rod 2.
Described pressure regulation stop valve also comprises the overcurrent cover 12 that is arranged on flow-off joint 5 bosom position, and overflow can be made so more stable.
Described high-pressure water outlet 10 is 3, to be separately positioned in the middle part of valve body 1 with high pressure water import 9 at a distance of the position of 90 °, 180 °, 270 °, can to select arbitrarily a use according to mounting point.
Inner peripheral surface, valve pocket 4 lower outer circumferential face and flow-off joint 5 upper end inner peripheral surface and be equipped with seal ring between flow-off joint 5 upper end outer circumferential face and through hole 8 bottom inner peripheral surface in the middle part of described handle 6 lower outer circumferential face and through hole 8 top inner peripheral surface, valve pocket 4 top outer peripheral surface and through hole 8.
Now pressure regulation stop valve using method provided by the invention is described below: first utilized the pressure gauge observed and be connected with pressure regulation stop valve by staff, while the mode of rotating hand rotatable handle 67 comes the position of regulating valve stem 2 in valve pocket 4, till making the high pressure water of discharging from high-pressure water outlet 10 reach required use pressure, at this moment the lower end of valve rod 2 blocks upper end-hole valve pocket 4 is positioned at below perforate 11 just.Under normal circumstances, the high pressure water of discharging in fluid end cylinder body is by the high pressure water import 9 that flowed into by high pressure water exhaust port pump head on this pressure regulation stop valve, then relative with high pressure water import 9 from valve pocket 4 perforate 11 enters in the annular space between valve pocket 4 and valve rod 2, flow into high-pressure water outlet 10 by perforate 11 corresponding with high-pressure water outlet 10 on valve pocket 4 afterwards, be supplied to receiving vessel for user finally by the pipeline be connected with high-pressure water outlet 10.When the high-pressure water pressure of discharging in fluid end cylinder body is too high, staff can utilize rotation hand valve rod 2 to be moved up the method for 7 according to manometric reading, upper end-hole valve pocket 4 is positioned at below perforate 11 is left, till making the high pressure water of discharging from high-pressure water outlet 10 reach required use pressure to make the lower end of valve rod 2.At this moment, partial high pressure water will overlap in 12 inflow flow-off joints 5 through overcurrent, finally drain in overflow vessel from flow-off joint 5, reach the object of pressure release thus.
