Abstract
The utility model discloses a kind of Provincial Rink ice stadium pipeline air exhaust water device, wherein, comprise pipeline, described pipeline arranges automatic control pressure vent, air collector is set in the joint of described automatic control pressure vent and pipeline; When pipeline passes through above obstacle, automatic control pressure vent is set above pipeline, as pipeline pass through into below obstacle U-shaped recessed time, 1 outlet valve is set this segment pipe two ends height point is each.The Provincial Rink ice stadium pipeline air exhaust water device that the utility model provides, utilize gas light during design, principle up in water, water supply direction is consistent with gas direction, gas is converged rapidly to air collector and is automatically discharged by automatic control pressure vent, backwater direction is contrary with gas traffic direction, avoids backwater gas enclosure.
Description
Technical field
The utility model relates to a kind of outlet valve, particularly relates to a kind of Provincial Rink ice stadium pipeline air exhaust water device.
Background technique
In prior art, the system balancing of Provincial Rink ice stadium pipeline is good again, if there is gas stifled or failed, the solution that gas blocks up will be fully that water supply security is requisite.Can find out by calculating, the solution that gas blocks up has two kinds of approach, and one tries every possible means to bleed off gas column, destroys gas column balance; Another kind of approach is the circulation damage by water increasing parallel branch, but in engineering practice, increases the increasing that circulation damage by water can bring circulating pump head, do not possess operability in normal Engineering Projects.Destroying the stifled most effective method of gas is try every possible means to bleed off gas column.According to practical experience, traditional bleed valve design, to system exhaust poor effect, for this reason, by having carried out a series of improvement in engineering practice, the utility model proposes Provincial Rink ice stadium pipeline air exhaust water device in.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of Provincial Rink ice stadium pipeline air exhaust water device, by increasing air collector, being converged rapidly by gas to air collector and automatically discharging, avoiding backwater gas enclosure.
The utility model is solve the problems of the technologies described above the technological scheme adopted to be to provide a kind of Provincial Rink ice stadium pipeline air exhaust water device, wherein, comprises pipeline, described pipeline arranges automatic control pressure vent, arrange air collector in the joint of described automatic control pressure vent and pipeline.
Above-mentioned Provincial Rink ice stadium pipeline air exhaust water device, wherein, arranges automatic control pressure vent when pipeline passes through above obstacle above pipeline, as pipeline pass through into below obstacle U-shaped recessed time, 1 outlet valve is set this segment pipe two ends height point is each.
The utility model has following beneficial effect relative to prior art: the Provincial Rink ice stadium pipeline air exhaust water device that the utility model provides, utilize gas light during design, principle up in water, water supply direction is consistent with gas direction, gas is converged rapidly to air collector and is automatically discharged by automatic control pressure vent, backwater direction is contrary with gas traffic direction, avoids backwater gas enclosure.

Embodiment
Below in conjunction with drawings and Examples, the utility model will be further described.
Fig. 1 is the schematic diagram of traditional Provincial Rink ice stadium pipeline air exhaust water apparatus structure.The schematic diagram of the Provincial Rink ice stadium pipeline air exhaust water apparatus structure that Fig. 2 provides for the utility model.
The Provincial Rink ice stadium pipeline air exhaust water device that the utility model provides, comprises pipeline 3, and described pipeline 3 arranges automatic control pressure vent 1, arranges air collector 2 at described automatic control pressure vent 1 with the joint of pipeline 3; When pipeline 3 passes through above obstacle, automatic control pressure vent 1 is set above pipeline, as pipeline 3 pass through into below obstacle U-shaped recessed time, 1 automatic control pressure vent 1 is set this segment pipe 3 two ends height point is each.
Utilize gas light during design, principle up in water, water supply direction is consistent with gas direction, and converged rapidly by gas to air collector 2 and automatically discharge, backwater direction is contrary with gas traffic direction, avoids backwater gas enclosure.As shown in Figure 1, near valve body self exhaust, gas-liquid separation insufficient space, lacks air collector 2 transition to traditional automatic control pressure vent 1, causes exhaust not smooth.
The control overflow of automatic control pressure vent 1:
1, the requirement in strict accordance with design drawing arranges outlet valve;
2, when when pipeline 3 is long, drawing no requirement (NR) arranges automatic control pressure vent 1, answer according to the form below to be set to: caliber (mm) below DN300, the distance (Km) of the spacing pipeline 3 of valve is within 1 ~ 1.5Km; Caliber (mm) below DN200, the distance (Km) of the spacing pipeline 3 of valve is within 0.5Km.
3, when pipeline 3 runs into obstacle and need pass through in laid processes: as passed through above obstacle, 1 automatic control pressure vent 1 is set at this segment pipe 3; As pass through into below obstacle U-shaped recessed time, 1 automatic control pressure vent 1 is set this segment pipe 3 two ends height point is each.
4, when pipeline 3 corner angle is greater than 90 degree, when namely there is current situation against the current, the energy of this position water is that pressure conversion of energy is very fast by kinetic transformation, and streamflow regime is very disorderly, there will be a large amount of vortex.There is negative pressure and cause the vaporization of water in vortex region, thus should add automatic control pressure vent 1 in this position.
Although the utility model discloses as above with preferred embodiment; so itself and be not used to limit the utility model; any those skilled in the art; not departing from spirit and scope of the present utility model; when doing a little amendment and perfect, therefore protection domain of the present utility model is when being as the criterion of defining with claims.
Claims (2)
1. a Provincial Rink ice stadium pipeline air exhaust water device, is characterized in that: comprise pipeline, and described pipeline arranges automatic control pressure vent, arranges air collector in the joint of described automatic control pressure vent and pipeline.
2. Provincial Rink ice stadium as claimed in claim 1 pipeline air exhaust water device, it is characterized in that: when pipeline passes through above obstacle, automatic control pressure vent is set above pipeline, as pipeline pass through into below obstacle U-shaped recessed time, 1 outlet valve is set this segment pipe two ends height point is each.
