Abstract
The utility model discloses a gas burning gate valve with pollutant discharging device, which is provided with a valve body, a valve cover, a valve rod and a valve plate which is arranged inside the valve body. A valve rod nut and a handwheel are arranged on the upper end of the valve rod, and an opening hole and a water collection gutter plugged with a flange are arranged at the bottom of a gate chamber inside the valve body, and the flange is provided with pipe thread inside and connected with a pollutant discharging ball valve. The impurities and condensed water in the gate chamber can be eliminated by the gas burning gate valve during operation, and the gate valve is convenient for operation and can be widely used for gas pipelines.
Description
Affiliated technical field
The utility model relates to the gate valve technical field, specifically a kind of Gas-combustion valve that is provided with sewage draining exit in the gate valve bottom.
Background technique
At present, contain more tiny foreign material and water of condensation in the domestic city gas ductwork, cut as iron oxide, welding slag, tar, naphthalene and opening iron etc.The general bottom, valve plate chamber that all is collected at gate valve is easy to make gate valve inflexible phenomenon, easy especially in the winter time freezing gate valve to occur in the switching manipulation process, cause fit badly crucial moment, open motionlessly, even affect accident treatment adversely, directly influence the normal gas transmission and distribution operation of pipe network.Carrying out conventional blowdown then needs to suspend pipe network operation, dismantles valve gap and removes foreign material, and complicated operation influences the normal gas transmission and distribution of pipe network.
Summary of the invention
The purpose of this utility model is exactly the deficiency that exists technically at existing Gas-combustion valve, provides a kind of and can get rid of foreign material in the gate valve plate chamber and a kind of Gas-combustion valve with drainage device of water of condensation easily in pipe network operation.
The utility model realizes that above-mentioned technology does the technological scheme of employing and be: the Gas-combustion valve of this band drainage device, be provided with valve body, valve gap, valve rod and be arranged on the interior valve plate of valve body, be provided with Stem Mut and handwheel in the upper end of valve rod, mainly be that flashboard chamber bottom in valve body is provided with logical opening and with the collecting annulus of flange shutoff, be equipped with pipe thread in the flange, by the Blowoff ball valve of pipe thread connecting band sewage draining exit.
The utility model advantage compared with prior art: mainly be reasonable in design, manipulate very convenient.Meter is offered for logical in bottom, gate valve flashboard chamber, uses the flange shutoff, and flange center's design pipe thread is installed Blowoff ball valve by pipe thread.If directly mounting flange ball valve of ad hoc requirement is arranged.Opening ball valve when getting rid of water of condensation and tiny foreign material just can blowdown.If foreign material more greatly closing gate valve dismantle shutoff valve orchid and carry out blowdown, all blowdown work does not influence the normal gas transmission and distribution operation of gas ductwork.
Description of drawings
Below in conjunction with the drawings and specific embodiments to being elaborated by model utility:
Fig. 1 is a structural representation of the present utility model.
1. valve bodies among the figure, 2. valve plate, 3. valve rod, 4. valve gap, 5. Stem Mut, 6. handwheel, 7. rubber seal, 8. pipe thread, 9. flange, 10. double-screw bolt, 11. nuts, 12. ball valves.
As shown in drawings: the Gas-combustion valve of this band drainage device, be provided with valve body 1, valve gap 4, valve rod 3 and be arranged on valve plate 2 in the valve body 1, be provided with Stem Mut 5 and handwheel 6 in the upper end of valve rod 3, bottom, flashboard chamber in the valve body 1 is provided with logical opening and with the collecting annulus 13 of flange 9 shutoff, be equipped with pipe thread 8 in the flange 9, by the Blowoff ball valve 12 of pipe thread 8 connecting band sewage draining exits 14.Surface of contact at valve body 1 and valve plate 2 is respectively reserved rectangle groove up and down, embedded rubber seal 7, and rubber seal 7 has certain decrement, can realize the elastic packing zero leakage.
