Description
Technical field
The present invention relates to the valve that uses in the heating plant in a kind of industry, specifically, relate to a kind of rough gas safety anti-explosive repid cut-off valve that is used for gas pipe line.
Background technique
The coal gas that China is metallurgical, mechanical and the widely-used industrial gas station of other hot working industries produces; In order to control the switch of coal gas, in the gas pipe line of heating plant, cut-off valve need be set.Owing to contain more water, dust and tar in this coal gas; Even if having through detar and dedusting; Also still contain a small amount of tar and dust etc.; Common cut-off valve perhaps can not cut off fully, perhaps after cut-out, is clung smooth opening again by tar, therefore this cut-off valve is required to be swift in motion and good airproof performance.
Each rough gas user can only adopt the water seal cut-out mode that manual work discharges water at present, and this mode leans on the fluctuation in stage in the water-sealing valve (case/groove) to realize shutoff or unlatching to rough gas.But the fluctuation in stage process is slow, can not realize the fast shut-off to rough gas.And when gas burning system broke down, this cut-out mode slowly made gas burning system have very big potential safety hazard, and domestic existing many case that explosion of fire damp causes the person and equipment accident takes place.
Summary of the invention
What the present invention will solve is that existing rough gas cut-off valve is because of turn-offing technical problem not in place or that turn-off speed is blasted slowly; A kind of rough gas safety anti-explosive repid cut-off valve is provided; Can fast and safely cut off rough gas or visceral-qi body reliably, can prevent bonded again and obstruction, the permanent use.
In order to solve the problems of the technologies described above, the present invention is achieved through following technological scheme:
A kind of rough gas safety anti-explosive repid cut-off valve; Comprise the water seal valve body that is used for internal storage water, said water seal valve body top is provided with capping, and said water seal valve body is provided with the gas inlet adapter and gas exit is taken over; The outlet that said gas inlet is taken over up and its top be provided with belljar valve; Said belljar valve top is connected in an end of lever through guide rod, and the other end of said lever is connected with drive unit, is provided with fulcrum in the middle of the said lever.
Said drive unit is wherein a kind of of cylinder, oil hydraulic cylinder or Motorized lift device.
The other end of said lever is provided with manual rod.
Bottom or the sidepiece that is arranged at said water seal valve body taken in said gas inlet.
Said gas exit is taken over top or the sidepiece that is arranged at said water seal valve body.
The invention has the beneficial effects as follows:
(1) the present invention falls below the water level in the water seal valve body through drive unit or manual rod control belljar valve, realize rough gas cut-out fully fast and safely, and cut-off valve does not have bonding phenomenon the work that whole device can be reliably and with long-term.
(2) the present invention can regularly remove booty and the tar in the rough gas, guarantees the use of this cut-off valve long-term safety.
(3) the present invention is except that automatic control, where necessary also can artificial complete operation, realize that manual safety switches.
(4) the present invention has system's explosion-proof relief function, and when security incident (like explosion of fire damp) appearred in pipe-line system, water seal of the present invention was a very sensitive explosion-proof relief point, had the effect of protective system device security.
(5) the present invention can be applicable to the cut-out safely and fast of rough gas system and other visceral-qi systems, can on all types of industries producer gas and other visceral-qi body pipeline, generally be applicable.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
Among the figure: 1: air supply header, 2: gas inlet is taken over, and 3: the water seal valve body, 4: belljar valve, 5: gas exit is taken over, and 6: capping, 7: guide rod, 8: lever, 9: pole, 10: manual rod, 11: cylinder, 12: pilot solenoid valve.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is made further detailed description:
Shown in accompanying drawing, present embodiment has disclosed a kind of rough gas safety anti-explosive repid cut-off valve, comprises the water seal valve body 3 of tubular, water seal valve body 3 inner waters, and the top is connected with capping 6 through flange.Water seal valve body 3 upper portion side wall are provided with gas exit and take over 5, and the bottom is provided with the gas inlet that is communicated with air supply header 1 and takes over 2, and the outlet of gas inlet adapter 2 is provided with up.Gas inlet is taken over 2 tops and is provided with belljar valve 4, and the top of belljar valve 4 is connected in an end of lever 8 through guide rod 7, and the middle part of lever 8 is fixed on the water seal valve body 3, as fulcrum through pole 9.The other end of lever 8 is respectively arranged with manual rod 10 and cylinder 11, and cylinder 11 is provided with pilot solenoid valve 12.Cylinder 11 also can replace to oil hydraulic cylinder or Motorized lift device as drive unit.
The state that the combustion gas of described position is cut off by water seal fully like accompanying drawing.When needs are opened rough gas, by cylinder 11 effect, affect guide rod 7 to move upward and belljar valve 2 is mentioned through lever 11, make rough gas get into water seal valve body 3, make gas inlet take over 2 and take over 5 with gas exit and connect, thereby to gas firing equipment air feed.When the urgent fast shut-off coal gas of needs, cylinder 11 actions, guide rod 7 moves downward, and belljar valve 4 falls rapidly and inserts in the water, accomplishes the cut-out task, realizes the purpose of turn-offing safely and fast.Open or turn-off and transmit signal by sending with the flame detector of installing on the gas firing equipment, when taking place to stop working, flame detector sends signal to pilot solenoid valve 10 when device is reported to the police; Solenoid valve 10 conductings; Gas supply is cut off in belljar valve 2 work, reaches explosion-proof purpose.In case actuator temporary derangement occurs and causes malfunctioningly automatically, the operator can spur manual rod 10 fast, and manual operation realizes that manual safety switches, and makes that valve is quick and complete closes.
Sticking foreign material major parts when rough gas is flowed through this cut-off valve such as dust in the rough gas and tar fall into the water, and can pass through periodic cleaning and remove, and guarantee that this cut-off valve long-term safety uses.In addition, when security incident (explosion of fire damp) appearred in pipe-line system, the water seal of this cut-off valve still was a very sensitive explosion-proof relief point, had the effect of protective system device security.
The position that gas inlet adapter 2 and gas exit adapter 5 are not limited in the foregoing description among the present invention; Go out, advance down that side goes out on the flow of gas direction is advanced under can being, side advances that side goes out and side goes out on advancing; Therefore gas inlet adapter 2 can be arranged at the bottom or the sidepiece of water seal valve body 3, and gas exit adapter 5 is arranged at the top or the sidepiece of water seal valve body 3.When gas inlet adapter 2 is arranged at water seal valve body 3 sidepieces, need make its outlet up through elbow.
Although combine accompanying drawing that the preferred embodiments of the present invention are described above; But the present invention is not limited to above-mentioned embodiment, and above-mentioned embodiment only is schematically, is not restrictive; Those of ordinary skill in the art is under enlightenment of the present invention; Not breaking away under the scope situation that aim of the present invention and claim protect, can also make the concrete conversion of a lot of forms, these all belong within protection scope of the present invention.
