Abstract

The utility model relates to a compressed air condensation water automatic discharge dewatering device, which is characterized in that an upper closing cap is connected with an air-intake system of the pilot wire, and a lower closing cap lower part is provided with an air-operated drain valve. One end of the pilot valve is connected with the upper closing cap by the compressed air tube, and the other end is connected to the lower closing cap process through an air supply control duct. The bottom of the valve body is provided with an air-intake opening and a water-intake opening, and a signal valve is arranged in the middle, and a thimble is arranged on the signal valve. The upper cap is respectively provided with a clip ring, a sealed body and an emptying valve downward, and a venting hole is arranged on the emptying valve. The advantage of the compressed air condensation water automatic discharge dewatering device is that the disadvantage of usually making use of the floater buoyance and the gas pressure to open or close the pollution discharge, and the disadvantage that the pollution discharge opening is small are overcome. The compressed air condensation water automatic discharge dewatering device can dewater and discharge pollution automatically, and is safe and reliable, etc.

Description

The leading type automatic steam trap

The utility model is a kind of compressed air system, the condensed water steam trap connection of discharging automatically, especially relate to a kind of by ponding tub assembly, floater component, be installed in upper cover gas handling system, be installed in down the leading type automatic steam trap that the drainage of capping is formed.

At present, known STEAM TRAP has two kinds substantially, a kind of is to utilize water that the pressure of the buoyancy of ball float or keg float, gas is done manual work or close the purpose that STEAM TRAP reaches the draining blowdown, thisly generally be designed to φ 3mm～φ 5mm because of the weight of ball float, keg float and the drain port that sealing area is limit at drain port place, often cause because of the impurity in the pipe-line system or greasy dirt block drain port, make it cisco unity malfunction.Another kind is the STEAM TRAP that adopts time relay control, this electrical signal that regularly sends that utilizes opens and closes electric control valve, because of opening and closing the time lag is constant, and the burden of condensed water is at random, often cause ponding in time not discharge or draining after can not in time close and cause exhaust to waste energy, performance does not reach desirable requirement, exists power consumption and unsafe factor simultaneously yet.

It is little that the purpose of this utility model provides a kind of volume, and sewage draining exit is safe and reliable greater than φ 12mm, the leading type automatic steam trap of consumes energy not, and it can in time be discharged condensed water in the compressed air system and the bigger greasy dirt of viscosity.

For solving above-mentioned purpose, solution of the present utility model is: the gas handling system that a band pilot valve is installed at the upper cover of ponding bucket, in following capping bottom a pneumatic sewage drain valve is installed, pilot valve one end is connected with upper cover by compressed air line, and the other end is connected pneumatic sewage drain valve by the source of the gas pilot line with lower seal cover process hole.The pilot valve bottom has air inlet, water inlet, and sentinel valve is equipped with in the intermediate portion, and thimble is housed on it, and loam cake down is equipped with spring flange, tegillum, spring, seal, atmospheric valve successively, has vent on the emptying valve seat.

The other end at pneumatic sewage drain valve can connect hand reversing gears.

The utility model adopts the upper cover gas handling system that pilot valve is installed, following capping drainage is installed the solution of pneumatic sewage drain valve, overcome and utilized float buoyancy, gas pressure to open usually to close blowdown, the shortcoming that blowdown is young, can hydrophobic automatically, blowdown, safe and reliable, be effective energy saving device.

Below in conjunction with drawings and Examples the utility model is described in further detail.

Fig. 1 is a schematic diagram of the present utility model

Fig. 2 is the utility model embodiment's an overall structure sectional view

Fig. 3 is the pilot valve assembly sectional view that the utility model is installed in ponding bucket upper cover

Fig. 4 is the sectional view of pilot valve shown in Figure 3 along the m-m line

Fig. 2 is the pilot valve automatic steam trap that forms according to Fig. 1 principle design, and Fig. 3 is pilot valve complete section figure in this STEAM TRAP.The utility model vertically is attempted by on the compressed air line, changing in compressed air line has condensed water, when having only pressurized air, float 5 is in the lower end of ponding bucket 4, break away from sentinel valve valve rod 22 above it, pressurized air is by the suction port on the pilot valve, by air inlet, the water inlet enters in the ponding bucket 4, at this moment, pressurized air is by the road 3 through being in telltale hole 23, a tunnel in the signal valve seats 19 in the pilot valve of normally open through 2 mouthfuls of the logical control of the cavity sources of the gas at sentinel valve valve rod 22 tops, behind the pipeline 2 of logical control source of the gas, enter down the auxiliary hole in the capping 8, diaphragm 9 is pressed on the valve port of pneumatic sewage drain valve 6, do not have this moment water to discharge from 10.Another road acts on below atmospheric valve 16 top the reaching, and under spring 14 and compressed-air actuated effect, the seal 15 on the atmospheric valve is pressed on the atmospheric valve valve seat 17, because the area difference that produces and the active force of spring do not make pressurized air be discharged into atmosphere from 18 holes.

In compressed air line, produced condensed water, under the condensed water action of gravity, from the hole of pilot valve, flow in the ponding bucket 4, make float 5 come-ups, it is up together that come-up back sentinel valve valve rod 22 drives two thimbles 20, when the buoyancy of float during greater than the sealing force on the atmospheric valve 16, atmospheric valve 16 is backed down, this moment, original control source of the gas pipeline 2 communicated with open to atmosphere 18 holes, diaphragm 9 tops in the pneumatic sewage drain valve and the gas of pipeline 3 release from 18 holes, when atmospheric valve 16 is opened, the seal 21 on the sentinel valve valve rod 22 will cut off pressurized air, not have this moment pressurized air to form the control source of the gas from 2 outputs, stockpiling the water that has pressure in ponding bucket 4 backs down diaphragm 9 and sprays from 10, after the ponding ejection, with removing under the water level in the ponding bucket, float is descending, its end face and sentinel valve valve rod break away from, reset with the sentinel valve valve rod, pilot valve returns to normally open again, and pneumatic sewage drain valve is closed.

Embodiment of the present utility model trial-produces successfully, intends being installed in the equipment branch company compressed air line.
