Abstract

The utility model provides an unpowered self-trapping condensing cylinder for middle pressure gas fuel, comprising a condensing cylinder and a gas fuel pipe. The upper end of a water draining pipe is extended out of the condensing cylinder and the gas fuel pipe, and the lower end of the water draining pipe is installed on the bottom part of the condensing cylinder. The lower end of the water draining pipe is sheathed with a floating ring, and the floating ring is provided with a transverse rod which is transversely penetrated through the vertical slot of the water draining pipe and is capable of sliding vertically. The transverse rod is provided with a push rod which is vertical to the transverse rod, the upper end of the push rod is provided with the center hole of a water draining valve seat, and a spring presses a ball to press against the center hole of the water draining valve seat. The utility model which is widely used for middle pressure gas fuel pipelines and is capable of saving large quantity of human power and materials has the advantages of simple structure, low cost, high reliability, self-water draining, no air leakage, and high safety.

Description

Unpowered self-trapping condensating apparatus for middle pressure gas fuel

The utility model relates to a kind of self-draining arrangement of gas pipeline, specifically, is compression ignite airsetting water vat in the automatic draining of a kind of no external force.

The container that water used, installs with fixed attention that known both at home and abroad gas is collected in the pipe network is the sky cylinder, only plays the water effect, does not have control or self-draining device, have to use artificial band pumper to go circulation regularly to draw water, it need be equipped with more manpower, equipment, pumper, and manpower, money are wasted all very big, careless slightly, promptly can ponding in the gas pipe, influence is supplied gas, and uses gas, and the grievous injury pipe network, long-term ponding is corrosion pipeline also.The self-draining arrangement of other known both at home and abroad purposes, act on the liquid medium with power drive pump class except that well-known, other mainly contain two big classes: the fluviograph of STEAM TRAP on the steam pipe system and industry and the civilian pond that all has everywhere, water tank, tower, to be buoyancy amplify and be transmitted to the control spool with lever their common feature, needs bigger space.91 years the 6th phases of China City Gas Society's publication " town gas " have been published Shanghai Gas Company " the semi-automatic condensate drain hydrophone of coal gas ", its feature is: refill a seal container outside empty condenser cylinder, adorn a floating drum in it, the valve seat spool, there are not other parts, but there is the danger that to put coal gas earlier, and only can closes automatically, need artificial earlier open air valve.

The purpose of this utility model is to provide can be automatic in a kind of middle pressure gaspipe network, safely the draining cylinder of draining.

For achieving the above object, the utility model adopts following technological scheme: it comprises condenser cylinder, fuel tube, it is characterized in that: stretch out outside condenser cylinder and the fuel tube waste pipe upper end, the lower end is placed in the bottom of condenser cylinder, and the waste pipe lower end is with water wing, and water wing is provided with vertical slot that crosses waste pipe and the cross bar that can vertically slide, vertically be provided with push rod on the cross bar with it, push rod is in waste pipe, and the upper end of push rod is the drain valve seat center hole, and spring compressing spheroid is pushed down the center hole of drain valve seat.

The utility model compared with prior art has following advantage:

1, can save a large amount of human and material resources;

2, simple in structure, with low cost, the reliability height;

Automatically draining, air tight, safe.

Fig. 1 is the utility model structural representation;

Fig. 2 is a waste pipe vertical slot part left view in the utility model.

The utility model is described in further detail below in conjunction with accompanying drawing:

In original condenser cylinder 1, the upper end is installed stretches out outside fuel tube 10 and the condenser cylinder 1, the lower end is placed in the waste pipe 2 of condenser cylinder 1 bottom, waste pipe 2 lower ends are with water wing 3, water wing 3 is provided with vertical slot 9 that crosses waste pipe 2 and the cross bar 8 that can vertically slide, and vertically is provided with push rod 7 on the cross bar 8 with it, and push rod 7 is in waste pipe 2, the upper end of push rod 7 is drain valve seat 6 center holes, and spring 4 compressing spheroids 5 are pushed down the center hole of drain valve seat 6.When in the condenser cylinder 1 gradually behind the ponding, water wing 3 rises, and drives cross bar 8, and push rod 7 backs down spheroid 5, and overcomes the elastic force of spring 4 simultaneously, relies on fuel tube 10 internal pressures, and water is extruded outside the condenser cylinders 1 by drain valve seat 6 from the end mouth of waste pipe 2; After the draining, drawdown, water wing 3 descends, and top power reduces or does not have top power, and spring 4 is pushed down spheroid 5, envelope position drain valve seat 6, water can not go out.Because of waste pipe 2 end openings have under the water level always, gas all the time in the above, combustion gas also can not leaked.
