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
By the supercharging of decompressor upstream, carry out the pressure removal by gas test interface TP2, TP3 during release during gas circuit relief line system requirements supercharging shown in Figure 2, one-way valve CV1, CV2 require reverse differential pressure to be no more than specified value P ' in the simultaneity factor.
During supercharging, decompressor downstream to the loine pressure between the two-way one-way valve sets up the operation point by decompressor and upstream pressure is determined, is designated as P behind the system sealing.Two-way one-way valve downstream pressure is basically identical, is P-Δ P.Δ P is determined by the one-way valve characteristic, is in a ratio of one in a small amount with pressure P.The reverse differential pressure P ' that P-Δ P allows greater than one-way valve.
Gas test interface blocking cap is connected (referring to Fig. 4) by worm structure with valve body, realize sealing (referring to Fig. 5) by the seal ring that is fixed on the valve body between blocking cap and valve body, the gas communication passage of valve inner is suitable with the pipeline internal diameter, and gas flow is very large during exhaust.When system passes through TP2, TP3 release, if a certain road nut is thrown off with seal ring first, one-way valve downstream and decompressor upstream and downstream pressurization gas will be by the rapid removals of this gas test interface on this path, another road one-way valve will bear size and be the reverse differential pressure of P-Δ P before unlatching, do not satisfy the product usage requirement.
Original processing mode, emphasize simultaneously removal of two-way gas test interface blocking cap, specific operation are cooperated by two people to be carried out simultaneously, but because the round section joint ring that seals with blocking cap on the valve body is positioned at blocking cap inside, can't observe and confirm the position, therefore be difficult to guarantee that two-way gas test interface opens simultaneously in the actual mechanical process, cause the unit usage requirement to satisfy.
The shortcoming that said method exists is mainly reflected in: (1) cooperation difficulty; (2) requirement that do not exceed standard of the reverse differential pressure that bears of deflation course one-way valve is difficult to satisfy.
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 satisfy 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 realizes the synchronously pipe-line system of venting from the downstream, its characteristics are that step is as follows:
(1) according to gas circuit relief line system interface and parameter, the synchronous venting that design processing is comprised of micropore vent connection, nut and plug three parts is with the micropore frock of exitting, the large latus rectum discharge channel of place of gas test interface self, realize the slow removal of system pressure, the assurance system realizes the gas test interface synchronization venting from the 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) the gas test interface valve blocking cap that two-way one-way valve downstream in the system is corresponding is replaced by micropore venting frock before the supercharging of gas circuit relief line system, and is screwed to sealing;
(3) test finishes, and during gas circuit relief line system unload, operator back out rapidly nut and the plug on the two-way gas test interface micropore venting frock simultaneously, realize synchronously venting.
The present invention's advantage compared with prior art is: 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 of venting on the frock by original gas test interface valve block internal diameter, and the pipeline deflation rate is significantly slowed down; The seal plug structure just can begin to exit as long as one unscrew in addition, and the simultaneously operating difficulty greatly reduces, and the time difference that begins to exit can ignore.The property of the present invention is directed to is strong, easily realizes, and is easy and simple to handle.

Embodiment
The gas circuit relief line system synchronization venting method that the present invention relates to is applicable to gas circuit relief line system shown in Figure 2.By adopting micropore venting frock, can reduce the deflation course flow, prolong deflation time, eliminate the asynchronous impact that brings of manual operation, thereby satisfy the synchronously requirement of 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 synchronous venting that design processing is comprised of micropore vent connection 3, nut 1 and plug 2 three parts is with the micropore frock (referring to Fig. 3) of exitting, 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 the 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 the release period of exhaust of pipe-line system each several part volume and needs.
(2) supercharging of gas circuit relief line system is front is replaced by micropore venting frock with two-way one-way valve CV1, corresponding gas test interface TP2, the TP3 valve blocking cap in CV2 downstream among Fig. 2, and is 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.
