Abstract
Provided is a synchronous deflation method for an air channel pressure-reducing pipeline system. The synchronous deflation method is used for the air channel pressure-reducing pipeline system. By a micropore closure mode of a micropore deflation tool, the deflation speed of the pipeline system is slowed down, and the synchronous deflation requirements are met. The characteristics and an interface mode of the pressure-reducing pipeline system are fully considered, an achieving mode is simple, the controllability is good, operation difficulty is greatly reduced, and achievement of the synchronous deflation requirements of the system is reliably guaranteed.
Description
Technical field
The present invention relates to a kind of Synchronous Radio gas method for gas circuit relief line system, be applicable to gas circuit relief line system.
Background technique
During the supercharging of the relief line of gas circuit shown in Fig. 2 system requirements, by the supercharging of decompressor upstream, during release, by gas test interface TP2, TP3, carry out pressure removal, in simultaneity factor, one-way valve CV1, CV2 require reverse differential pressure to be no more than specified value P '.
After system sealing, during supercharging, decompressor downstream by decompressor, sets up operation point to the loine pressure between two-way one-way valve and upstream pressure is determined, is designated as P.Two-way one-way valve downstream pressure is basically identical, is P-Δ P.Δ P is determined by one-way valve characteristic, is in a ratio of one in a small amount with pressure P.P-Δ P is greater than the reverse differential pressure P ' that one-way valve allows.
Gas test interface blocking cap is connected (referring to Fig. 4) with valve body by worm structure, between blocking cap and valve body, by the seal ring being fixed on valve body, realize sealing (referring to Fig. 5), the gas communication passage of valve inner is suitable with pipeline internal diameter, and during exhaust, gas flow is very large.When system is passed through TP2, TP3 release, if a certain road nut is first thrown off with seal ring, on this path, one-way valve downstream and decompressor upstream and downstream pressurization gas will be by the rapid removals of this gas test interface, another road one-way valve is the reverse differential pressure of P-Δ P by bearing size before unlatching, does not meet product usage requirement.
Original processing mode, emphasize two-way gas test interface blocking cap removal simultaneously, specific operation are coordinated and are carried out simultaneously by two people, but owing to being positioned at blocking cap inside with the round section joint ring of blocking cap sealing on valve body, cannot observe and confirm position, therefore in actual mechanical process, be difficult to guarantee that two-way gas test interface opens simultaneously, cause unit usage requirement to meet.
The shortcoming that said method exists is mainly reflected in: (1) cooperation difficulty; (2) requirement that the reverse differential pressure that deflation course one-way valve bears does not exceed standard is difficult to meet.
Summary of the invention
Technology of the present invention is dealt with problems and is: overcomes the deficiencies in the prior art, a kind of Synchronous Radio gas method for gas circuit relief line system is provided, and simple to operate, can meet usage requirement.
The technology of the present invention solution: a kind of Synchronous Radio gas method for gas circuit relief line system, be applicable to the gas circuit relief line system that is arranged symmetrically with by decompressor and downstream two-way one-way valve and other need to guarantee that two-way is arranged symmetrically with one-way valve and from downstream, realizes the pipe-line system of synchronous venting, its feature is that step is as follows:
(1) according to gas circuit relief line system interface and parameter, the micropore frock of exitting for the synchronous venting that design processing is comprised of micropore vent connection, nut and plug three parts, the large latus rectum discharge channel of place of gas test interface self, realize the slow removal of system pressure, assurance system realizes the gas test interface synchronization venting from one-way valve downstream, avoids causing single channel pressure to shift to an earlier date the problem of removal because of operation synchronism difference;
(2) before the supercharging of gas circuit relief line system, gas test interface valve blocking cap corresponding to two-way one-way valve downstream in system is replaced by micropore venting frock, and is screwed to sealing;
(3) test finishes, and during gas circuit relief line system unload, operator back out rapidly nut and the plug in two-way gas test interface micropore venting frock simultaneously, realize synchronously venting.
The present invention's advantage is compared with prior art: the present invention is by the micropore venting frock that changes the outfit, gas circuit relief line system unload channel diameter is converted to the micro-pore diameter in venting frock by original gas test interface valve block internal diameter, and pipeline deflation rate significantly slows down; Seal plug structure, as long as one unscrew, just can start venting in addition, and simultaneously operating difficulty greatly reduces, and starts time difference of exitting negligible.The property of the present invention is directed to is strong, easily realizes, easy and simple to handle.

Embodiment
The gas circuit relief line system synchronization venting method the present invention relates to, is applicable to the gas circuit relief line system shown in Fig. 2.By adopting micropore venting frock, can reduce deflation course flow, extend deflation time, eliminate the asynchronous impact bringing of manual operation, thereby meet the requirement of synchronous venting.
As shown in Figure 1, concrete steps of the present invention are as follows:
(1) according to gas circuit relief line system interface and parameter, the micropore frock (referring to Fig. 3) of exitting for the synchronous venting that design processing is comprised of micropore vent connection 3, nut 1 and plug 2 three parts, large latus rectum discharge channel with venting micropore 4 place of gas test interfaces self, realize the slow removal of system pressure, guarantee that gas circuit relief line system realizes the gas test interface synchronization venting from one-way valve downstream, avoid causing single channel pressure to shift to an earlier date the problem of removal because of operation synchronism difference; Micro-pore diameter can be determined according to pipe-line system each several part volume and the release period of exhaust needing.
(2) before the supercharging of gas circuit relief line system, two-way one-way valve CV1, corresponding gas test interface TP2, the TP3 valve blocking cap in CV2 downstream in Fig. 2 are replaced by micropore venting frock, and are screwed to sealing;
(3) test finishes, and during gas circuit relief line system unload, operator back out rapidly nut and the plug of the upper micropore venting of two-way gas test interface TP2, TP3 frock simultaneously, realize synchronously venting.
