Description

Orifice ring and packing assembly for packing seal of reciprocating piston compressor

technical field

The utility model relates to a reciprocating piston compressor, in particular to a throttling ring used for the packing seal of the reciprocating piston compressor and a packing assembly used for the reciprocating piston compressor.

Background technique

The packing assembly undertakes the important work of preventing compressed gas leakage, mainly relying on the packing ring to tightly hug the piston rod under the action of self-tightening force to form a seal. The role of the throttle ring in the packing assembly is to throttle the front end of the packing to reduce the load of the packing when sealing. Due to the working principle of the choke ring, there is a gap between the choke ring and the piston rod. Due to the existence of the gap, the choke ring cannot be well centered, and the throttling effect is not good, resulting in low working performance of the packing.

Utility model content

The purpose of the utility model is to overcome the deficiencies in the prior art and provide a throttling ring used for packing seals of reciprocating piston compressors.

In order to achieve the above-mentioned technical effects, the utility model adopts the following technical scheme: the throttling ring used for the packing seal of the reciprocating piston compressor includes a throttling ring body, the throttling ring body is in the shape of a ring, and the throttling ring The flow ring body is provided with an annular groove and at least two through holes. The annular groove is arranged on the inner wall of the choke ring body; the through hole is evenly arranged on the choke ring body along the same circumference, and one end of the through hole communicates with the outside world, and the other end of the hole The mouth communicates with the annular groove.

The utility model also provides a packing assembly for a reciprocating piston compressor, which includes a cylindrical packing body and the aforementioned throttling ring, the throttling ring is installed inside the packing body, and the throttling ring There is a gap with the packing body. The outer end opening of the through hole of the choke ring communicates with the gap between the packing body and the choke ring.

A further technical solution is: the filler body is provided with flanges, multiple stuffing boxes, diversion boxes, spacers, throttle boxes and pull rods, and the flange, multiple stuffing boxes, diversion boxes, spacers 1. The throttling box is installed on the filler body through the pull rod in turn.

A further technical solution is: a sealing ring is installed on the packing body, and the sealing ring passes through the pull rod and is arranged on the flange.

A further technical solution is: a retaining ring and a choke ring are installed in the stuffing box.

A further technical solution is: a decompression ring is installed in the spacer.

Compared with the prior art, the utility model has the following beneficial effects: because the throttling ring is evenly provided with through holes, the high-pressure gas can flow from the through holes into the gap between the packing body and the throttling ring, Thus, under the action of high-pressure gas, the throttling ring can be well centered and evenly distributed inside the filler body, thereby enhancing the throttling effect.

Detailed ways

Below in conjunction with the embodiment of the utility model, the utility model is further elaborated and illustrated.

Embodiment one:

As shown in Figure 1, the throttling ring used for the packing seal of the reciprocating piston compressor includes a throttling ring body 1, the throttling ring body 1 is in the shape of a ring, and the throttling ring body 1 is provided with an annular groove 2 and at least two through holes 3. The annular groove 2 is arranged on the inner wall of the choke ring body 1; the through holes 3 are uniformly arranged on the choke ring body 1 along the same circumference, for example, the through holes 3 are symmetrically arranged in pairs on the choke ring body 1 The upper or odd number of through holes 3 are arranged on the choke ring body at an equal angle to the same center of circle, and one end of the through holes 3 communicates with the outside world, and the other end communicates with the annular groove 2 . The through hole 3 can make the gas inside the choke ring flow well with the outside world, so that the choke ring can be arranged in the external environment in a balanced manner.

Embodiment two:

As shown in Figure 2-3, the packing assembly for reciprocating piston compressors includes a cylindrical packing body and the throttle ring 25 described in Embodiment 1, and the throttle ring 25 is installed inside the packing body , There is a gap 24 between the throttle ring 25 and the packing body. The choke ring 25 has at least two through holes, and the outer end of the through holes of the choke ring 25 communicates with the gap 24 between the packing body and the choke ring 25 . More preferably, the choke ring 25 has a pair of through holes, and the through holes are symmetrically distributed on the choke ring.
