Locating slot, the top of one ontology of valve body, the top of two ontology of valve body are fastened in locating slot, locating slot and one ontology top of valve body
Refractory ceramic fiber paper, the refractory ceramic fibre between one ontology of valve body, two ontology of valve body are set between portion, two bodies top of valve body
Paper bottom sets pressing plate, and multiple screws are fixed on top pressure closure after passing through pressing plate and refractory ceramic fiber paper.
6. a kind of coal oven dithio-gas according to claim 1 closes valve, which is characterized in that the retaining mechanism is by support
One, distinguish fixed branch in the both ends of support two, cross bar, clamping plate and check lock lever composition, one ontology of valve body and two ontology junction of valve body
Seat one, support two, one end of cross bar and support one are hinged, and the hinged-support being arranged on the middle part of cross bar and top pressure closure is hinged；Branch
Seat two is hinged with one end of clamping plate, and clamping plate is equipped with through slot；The other end that clamping plate is rotated upwardly into vertical direction rear transverse rod is certainly logical
It being passed through in slot, check lock lever is set on clamping plate, rotational handle is set at the top of check lock lever, lower part sets thread segment, and bottom sets hemispherical briquetting,
The corresponding thread segment opened up on threaded hole and check lock lever in the top of clamping plate cooperates, and check lock lever can lock cross bar after moving down
It is fixed, to realize the sealed connection of top pressure closure Yu valve body one, valve body two.
7. a kind of coal oven dithio-gas according to claim 6 closes valve, which is characterized in that between the hinged-support and cross bar
By stud connection, the hole on hinged-support with hinged shaft cooperation is slotted hole, and long axis is in the horizontal direction.
8. a kind of coal oven dithio-gas according to claim 1 closes valve, which is characterized in that set at the top of the sealing bottom cover

It seals and sets refractory ceramic fiber paper between the bottom of bottom cover and one ontology of valve body, the bottom of two ontology of valve body, multiple screws pass through
It is fixed after gasket, sealing bottom cover and refractory ceramic fiber paper with one ontology of valve body, two ontology of valve body of corresponding position.
9. a kind of coal oven dithio-gas according to claim 1 closes valve, which is characterized in that the top both ends of the valve plate point
Bolt hole is not set, fixed bolt when taking out for valve plate.
10. any one coal oven dithio-gas closes the installation and repairing method of valve as described in claim 1-9, which is characterized in that packet
It includes:
1) it is connect by the flange at both ends with crude gas pipeline in use, coal oven dithio-gas is closed valve；Unclamp the locking at top
Top pressure closure is gone on one side, first valve plate is inserted into valve plate slot by mechanism, and makes the card slot and two ontology of valve body at the top of valve plate
On arc convex edge snap-in location, then spring clip is installed；
2) when installing spring clip, grips said handle takes the spring clip that spring steel wire is inserted by valve plate in slot in, and spring steel wire is in bullet
Spring folder, which is taken in slot, generates flexible deformation to contract, since the side that spring clip takes slot in is bevel edge, the oriented valve of spring steel wire
The trend of one Slideslip of plate, elastic restoring force act on valve plate, are adjacent to valve plate and the end face of one ontology of valve body together；
3) after valve plate and spring clip are installed, top pressure closure is resetted, makes refractory ceramic fiber paper and one ontology of valve body, valve body
It is fitted closely at the top of two ontologies, the position of top pressure closure carries out appropriate adjustment by the slotted hole on hinged-support, then rotates
Check lock lever is pressed on the hemispherical briquetting of its bottom on cross bar；So far, coal oven dithio-gas is closed valve and is installed, and investment makes
With；
4) in use process, the dust that coal oven dithio-gas is closed in valve is accumulated in by bottom groove one, the valve body of one ontology of valve body
In the bottom space that the bottom groove two of two ontologies forms, when needing to clear up valve inner dust stratification, top pressure closure is first opened by bullet
Spring folder and valve plate take out, then sealing bottom cover is removed, and carry out deashing operation；
5) when dismantling valve plate, bolt is screwed in bolt hole at both ends at the top of it, after hooking bolt with hand or tool
Valve plate is proposed upwards；
6) after changing valve plate into orifice plate, coal oven dithio-gas, which closes valve, can be realized connectivity capabilities；
7) it installs, dismantle valve plate or orifice plate, and when cleaning dust stratification operation, first the ball valve on desorption tube is opened and passes through release
Pipe closes in valve to coal oven dithio-gas and is passed through inert gas, and ball valve is normally off under rest working conditions.
