Abstract
The utility model relates to a float balance type anti-gas leakage device, which belongs to the mechanical gas anti-leakage technical field. The utility model comprises a drainer, a brake valve, a connecting pipe, a short drain pipe, and a drain pipe; wherein, the drainer is connected with the gas pipeline through the connecting pipe; the short drain pipe is arranged on the upper part of the drainer and connected with the drainer, and the drain pipe is connected with the upper end of the short drain pipe; a mass balance, a connecting rod, a float, and a control valve of a ring plate with a through hole in the center are arranged on the inner upper end of the short drain pipe near the drain outlet; the ring plate is fixed inside the short drain pipe, the mass balance passes through the connecting rod of the ring plate and connects with the float, the float and the mass balance are hollow circular columns, and a limit stop is arranged on the top of the mass balance. The float is floated up under the action of the gas pressure and the condensed water, and the mass balance is driven to divorce from the through hole fracture surface of the ring plate through the connecting rod, the gas condensed water is ensured to drain efficiently, the sealing water drain can be prevented efficiently under the condition that the pressure is abnormal, and the gas anti-leakage function of the drainer is realized. The utility model has the advantages of simple production, safety and effectiveness, and low cost, etc.
Description
Technical field
The utility model relates to a kind of float counterweight type and prevents the gas leakage device.
Background technique
In large industrial enterprise, the gas pipe line gas transmission is carried out with setting up pipeline in the air.In order to prevent gas leakage, need effective sealing of a kind of hydathode and draining and can prevent that in the different time sealing water runs off in a large number, play a kind of safety installations of checking gas leakage.
In the prior art, hydathode is made of institutes such as tank body, gate valve, waste pipe, drain opening, pipeline section, short tubes, and the effective height of hydathode designs according to the gas pressure grade.This coal gas drainer can reach the habitual functional characteristics that has sealing, automatic draining and need not add water at ordinary times substantially, and it prevents that the gas leakage device has the ability of checking gas leakage.But the draining of this gas leakage preventing device realizes by the middle chamber lower valve plates.When the gas pressure unusual fluctuations in the pipeline, unconfined loss can take place in the sealing water in the hydathode under the impact of pressure surge, the cavity bottom valve plate of gas leakage preventing device just can move after coal gas takes place to leak, and therefore, gas leakage takes place easily still.
Summary of the invention
The purpose of this utility model provides and a kind ofly can prevent to seal current effectively lose under the state of pressure anomaly, and makes hydathode avoid the float counterweight type of gas leakage to prevent the gas leakage device.
In order to achieve the above object, solution of the present utility model is: comprise hydathode, gate valve, connecting tube, drain stub, waste pipe; Described hydathode is connected with gas pipe line by connecting tube, is equiped with gate valve on this connecting tube; Described drain stub is arranged at the top of hydathode and is communicated with it, and waste pipe is connected in the drain stub upper end; Nearly drain opening place, upper end is provided with a control valve in described drain stub, and described control valve comprises counterweight, connecting rod, float, ring flat-plate; Described ring flat-plate is fixed in the drain stub, and the centre has the through hole that is complementary with float, and this float can seal through hole; Small end is fixedly connected on the float lower end, and the through hole that the connecting rod lower end is passed on the ring flat-plate is connected with counterweight.
Described counterweight is a hollow cylinder, and its top is provided with block, guarantees to leave certain clearance when float floats to ring flat-plate, makes the drain stub conducting, plays the channeling of rapid draining.
Described float is a hollow cylinder, and the bottom is that hemisphere is crown, and its effect reaches good sealing.
Also be provided with the indication guide rod, the fixedly connected float of this indication guide rod top.
The utility model has solved at the hydathode water level and effectively prevented gas leakage under the gas pressure abnormal state, and this device is made simple, and cost is low, and certain promotion value is arranged.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A portion enlarged diagram of Fig. 1.
Embodiment
With reference to Fig. 1, Fig. 2, the utility model comprises hydathode 5, gate valve 2,4, connecting tube 3, drain stub 6, waste pipe 7; Described hydathode 5 is connected with gas pipe line 1 by connecting tube 3, is equiped with gate valve 2,4 on this connecting tube 3; Described drain stub 6 is arranged at the top of hydathode 5 and is communicated with it, and waste pipe 7 is connected in drain stub 6 upper ends; Nearly drain opening 61 places, upper end are provided with a control valve 8 in described drain stub 6, and this control valve 8 comprises float 81, ring flat-plate 82, connecting rod 83, counterweight 84; Described ring flat-plate 82 is fixedly arranged on nearly drain opening 61 places, upper end in the drain stub 6, and the centre has the through hole 821 that is complementary with float 81, and connecting rod 83 upper ends are fixedly connected on float 81 lower ends, and the through hole 821 that connecting rod 83 lower ends are passed on the ring flat-plate 82 is connected with counterweight 84; Float 81 is a hollow cylinder, and the bottom is that hemisphere is crown, and crown bottom is connected with counterweight 84 by connecting rod 83; Described counterweight 84 is a hollow cylinder, and its top is provided with block 85, and these indication guide rod 9 fixedly connected floats 81 tops pass drain stub 6 tops, and have positioning work piece 10 spacing, and this indication guide rod 9 also is equipped with colour code 11.
Runnability of the present utility model is as follows: drain opening sealing water level is under nominal situation, float 81 is under the effect of gas pressure, condensed water, upwards float by bottom linkage rod 83 and drive through hole 821 sections that hollow counterweight 84 breaks away from ring flat-plate 82, effectively discharge for guaranteeing gas condensed water, symmetrical block 85 is set at the top of counterweight 84, it is being floated in the process at float 81, the block 85 of counterweight 84 must withstand on the bottom of ring flat-plate 82 and form effective drainage channel, and coal gas, condensed water discharge by drain opening.Set indication guide rod 9 passes the hollow pipeline section of positioning work piece 10 on the float 81, and its effect can be judged the sealing water level with this according to upwards floating extension degree, and prevents float 81 swing inclinations.
