Room 4 fits closely, and the upper right of lock chamber 4 is provided with air hole 403, and the insertion of air hole 403 is arranged on lock chamber 4, lock chamber 4
Interior lower end is provided with seal disc 401, and seal disc 401 is fitted closely with lock chamber 4, and the lower part of seal disc 401 is provided with flashboard
402, flashboard 402 is fixedly connected with seal disc 401, and the lower part setting fluted 404 of flashboard 402, groove 404 and flashboard 402 are tight
Closely connected conjunction, the lower left side of lock chamber 4 are provided with water inlet pipe 5, and the insertion of water inlet pipe 5 is arranged on lock chamber 4, outside the right side of water inlet pipe 5
Wall is provided with into water pipe flange 501, intake pipe flange 501 and the closely welding of water inlet pipe 5, the row of being provided on the right side of the lower part of lock chamber 4
Water pipe 6, the insertion of drainpipe 6 are arranged on lock chamber 4, and the outer right wall of drainpipe 6 is provided with draining pipe flange 601, drain tube method
Orchid 601 is closely welded with drainpipe.
Further, lock chamber flange 3 is set there are two ring flange, and upper flange disk and threaded sleeve 202 closely weld, lower part
Ring flange and 4 top of lock chamber are closely welded, and are bolted between two ring flanges, are unloaded the bolt on 3 top of lower chamber flange
When can separate ring flange, and lock chamber 4 is opened and takes out inner sealing disk 401 and flashboard 402, to being cleared up inside lock chamber 4
Maintenance.
Further, the upper end of valve rod 7 is fixedly connected with handwheel 1, and the other end is closely connect with seal disc 401, works as gate valve
When unlatching, seal disc 401 and flashboard 402 need to rise, since handwheel 1 is fixed by valve rod 7 and seal disc 401, rotation hand wheel 1
When, band ovable valve stem 7, seal disc 401 and flashboard 402 rotate to rise flashboard 402 together, compared to direct pull-up flashboard
402 is more laborsaving, and not easy-to-draw bad seal disc 401.
Further, seal disc 401 is in " cylinder " shape, and the inner wall of outer wall and lock chamber 4 fits closely, when gate valve is closed, pipe
Road internal fluid pressure is larger, easily infiltration lock chamber 4, corrosion or impact failure is caused to 4 internal structure of lock chamber, using " cylinder "

Press the stabilization to guarantee gate valve opening and closing.
Further, the concave surface radian of groove 404 and the convex surface radian of 402 lower part of flashboard mutually agree with, when flashboard 404 is fallen
When, convex surface and the groove 404 of 402 lower part of flashboard are adjacent to, to disconnect pipeline water flow inside, and due in flashboard 402 and pipeline
The contact surface of wall is arc, and water flow pressure can not be applied directly in the pipeline of the other end, so that gate valve closing is even closer, is prevented
Only gate valve leak.
Working principle：Water inlet pipe 5 is connect by pipe flange 501 of intaking with external pipe first, then pipe flange will be drained
It is connected with another section of external pipe, when gate valve is opened, rotates counterclockwise handwheel 1, handwheel 1 is rotated with ovable valve stem 7, and valve rod 7 is logical
Crossing external convex thread 701, threadingly 202 inner wall of casing rises, and drives the rotation of seal disc 401 to rise, seal disc 401 drives flashboard
402 rise, and open gate valve, when gate valve is closed, rotate clockwise handwheel 1, valve rod 7 passes through external convex thread 701 threadingly casing
The decline of 202 inner walls drives the rotation decline of seal disc 401, and seal disc 401 drives flashboard 402 to fall, 402 top surface of flashboard and groove
404 are adjacent to, thus closing gate valve, seal disc 401 rises, and 4 inner air of lock chamber is discharged air hole 403, under seal disc 401
Outside air is then sucked lock chamber 4 by drop, air hole 403, unclamps 3 internal-flange bolt of lock chamber flange, and two ring flanges separate, and opens lock
4 inner sealing disk 401 of lock chamber and flashboard 402 are taken out by upper opening in room 4.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired
Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
