Abstract
The invention discloses a damping stainless steel joint which comprises a nut with internal screw thread and a joint main body with external screw thread, and is characterized in that the internal screw thread on the nut is connected with a damping pump to form an inlet; the external screw thread on the joint main body is connected with an outer pipeline to form an outlet, and the joint main body is provided with a slot hole which is communicated with an internal screw thread hole of the nut; and the damping stainless steel joint also comprises a damp one end of which is clamped in the slot hole. In the invention, the defects of the existing damping equipment is overcome, the damping stainless steel joint for the damping pump is provided, and thus the damping stainless steel joint has the characteristics of good damping effect, low cost, simple structure, safety and reliability, long service life, and the like.
Description
One, technical field
The present invention relates to a kind of stainless joint, especially a kind of damping stainless joint for the damping pump.
Two, background technique
Hydraulic servo control system is large, lightweight with its driving power, acceleration performance is good, fast response time and precision advantages of higher, is widely used in the numerous areas such as metallurgy, mine, iron and steel, military affairs and aviation.With regard to its dynamic characteristic, the main deficiency of hydraulic control system is that damping is smaller, is generally less than 0.3, is underdamping.For improving the damping of system, improve its dynamic characteristic, often adopt following measure: offer the bypass leakage passage; Adopt the servovalve of positive opening; Add hydraulic damper.Front 2 kinds of methods have reduced Pressure gain and system stiffness, have strengthened power loss, therefore for high-power system, adopt last a kind of method more.The effect of hydraulic damper is to utilize the oil hydraulic cylinder that is full of hydraulic oil, by damping control valve or damping orifice, produces pressure difference in oil hydraulic cylinder two chambeies, thereby load is produced damping force, improves the dynamic performance of system.
Three, summary of the invention
The objective of the invention is to solve the deficiency of above-mentioned existing damping device, a kind of damping stainless joint for the damping pump be provided, make that it has that damping is good, at the bottom of the cost, the characteristics such as simple in structure, safe and reliable and long service life.
The objective of the invention is to adopt following scheme to realize: a kind of damping stainless joint, it comprises with the nut of internal thread and externally threaded adapter body is arranged, is characterized in: the internal thread on the described nut and damping pump are connected to become import; Outside thread on the above-mentioned adapter body and outer pipeline are connected to become outlet, have a slotted hole that is communicated with nut inner threaded hole in adapter body; Above-mentioned damping stainless joint comprises that also an end is stuck in the damping in the slotted hole.
Above-mentioned damping one end is stuck in the slotted hole, the other end is unsettled in nut, the external diameter of damping is than the slightly large formation interference fit of slotted hole internal diameter, damping is stuck in the slotted hole of adapter body and does not drop, during hydraulic shock damping in entering nut, the inwall wall is blocked in the damping that contacts with the adapter body inwall tightly, and damping neither can wholely be poured in the slotted hole, can not drop in the nut again.Easier when damping is installed, the outer surface of damping has two grooves, establishes the conical surface at an end of damping, makes its easier entering in the slotted hole.
Above-mentioned damping is the cylindrical body of an end sealing, a major diameter inner chamber is arranged in it, be provided with pore at closed end and be communicated with inner chamber, and be the conical surface between pore and the inner chamber and dwindle, form a pore flow controller, liquid enters the damping inner chamber by the nut import, when flowing through again pore, because the viscous effect of liquid produces linear loss, the damping function that relaxes pressure pulsation impact is played in the resistance of formation liquid.
Slotted hole on the above-mentioned adapter body will form a slotted hole flow controller, when liquid is flowed through slotted hole by pore in the damping, form the liquid resistance, play the damping function that again relaxes pressure pulsation impact.
The present invention adopts the beneficial effect of such scheme to be: 1) Double damping, and damping is good, applicable to the damping pump of various scopes; 2) all be comprised of mechanical part, joint stimulates the menstrual flow big or small unfettered, safe and reliable; 3) whole damping joint is simple in structure, low price, and long service life;
Four, description of drawings
Fig. 1 is the three-dimensional structure diagram of damping stainless joint of the present invention;
Fig. 2 is the main sectional view of damping stainless joint of the present invention;
Fig. 3 is the main sectional view of damping in the figure damping stainless joint of the present invention.
As follows to the label declaration in each width of cloth accompanying drawing:
The 1-internal thread; The 2-nut; The 3-outside thread; The 4-adapter body; The 5-damping; The 6-slotted hole; The 7-groove; The 8-conical surface; The 9-inner chamber; The 10-pore.
Five, embodiment
Be described in detail below in conjunction with the embodiment of accompanying drawing to damping stainless joint of the present invention.
As shown in Figure 1, 2, be the structural drawing of damping stainless joint of the present invention, a kind of damping stainless joint, it comprises with the nut 2 of internal thread 1 and the adapter body 4 of outside thread 3 is arranged that the internal thread 1 on the nut 2 is connected to become import with the damping pump; Outside thread 3 on the adapter body 4 is connected to become outlet with outer pipeline, has a slotted hole 6 that is communicated with nut 2 interior threaded holes at joint; The damping stainless joint comprises that also an end is stuck in the damping 5 in the slotted hole 6.
As shown in Figure 2, damping 5 one ends are stuck in the slotted hole 6, and the other end is unsettled in nut 2.
As shown in Figure 2, the external diameter of damping 5 is than the slightly large formation interference fit of slotted hole 6 internal diameters, damping 5 is stuck in the slotted hole 6 of adapter body 4 and does not drop, during hydraulic shock damping 5 in entering nut 2, block tightly the inwall wall with the damping 5 that adapter body 4 inwalls contact, damping 5 neither can wholely be poured in the slotted hole 6, can not drop in the nut 2 again.Easier when damping 5 is installed, at the outer surface of damping 5 two grooves 7 are arranged, establish the conical surface 8 at an end of damping 5, make its easier entering in the slotted hole 6.
As shown in Figure 3, damping 5 is the cylindrical body of an end sealing, and a major diameter inner chamber 9 is arranged in it, is provided with pore 10 at closed end and is communicated with inner chamber 9, and being the conical surface between pore 10 and the inner chamber 9 dwindles, form a pore flow controller, liquid enters damping 5 inner chambers 9 by nut 2 imports, when flowing through pore 10 again, because the viscous effect of liquid, produce linear loss, form the liquid resistance, play the damping function that relaxes pressure pulsation impact.
As shown in Figure 2, the slotted hole 6 on the adapter body 4 will form a slotted hole flow controller, when liquid is flowed through slotted hole 6 by damping 5 interior pores 10, form the liquid resistance, play the damping function that again relaxes pressure pulsation impact.
