Description
Technical field
The utility model relates to a kind of fluid control valve, particularly a kind of elastic seat sealed encryption gate valve.
Background technique
Gate valve mainly plays a part to block in pipeline or connects fluid in the pipeline, and it is widely used in using as the device that blocks or connect fluid on the fluid pipe-lines such as tap water, oil, chemical industry, electric power, food, medicine, metallurgy, energy system.
Existing encryption gate valve mainly comprises valve body, bottom flange, bonnet, flashboard, valve rod and unlatching key, described bottom flange is located at the valve body top, described bonnet is located at the bottom flange top, described valve body vertically part offers the fluid passage that connects medium, described fluid passage has water intake and water outlet, described flashboard can be gone up, being located between the interior described water intake of valve body and the water outlet of lower lifting, described valve rod one end passes bottom flange and is threaded with flashboard, the other end is fixedly connected with bonnet by bearing pin, be provided with magnetic locking mechanism between described bottom flange and the bonnet, described unlatching key is provided with for the release mechanism of removing magnetic locking mechanism, the position of matching with flashboard in the bottom surface of above-mentioned its valve body fluid passage of encryption gate valve is provided with depression, the easily accumulation in this depression of dirt that is mingled with from the flowing medium of fluid passage process, the dirt of piling up can not put flashboard in place in traling, thereby so that flashboard can not be fully and the valve body inner seal produce water leakage phenomenon, sealing effect is bad.
Summary of the invention
For the problems referred to above, the utility model proposes a kind of elastic seat sealed encryption gate valve, overcome that Gate-valve sealing does not sternly cause fluid leaks in the prior art, not only affect gate valve working life, also affect the problem of working environment.
For solving this technical problem, the utility model is taked following scheme: a kind of elastic seat sealed encryption gate valve, comprise valve body, bottom flange, bonnet, flashboard, valve rod and unlatching key, described bottom flange is located at the valve body top, described bonnet is located at the bottom flange top, described valve body vertically part offers the fluid passage that connects medium, described fluid passage has water intake and water outlet, described flashboard can be gone up, being located between the interior described water intake of valve body and the water outlet of lower lifting, described valve rod one end passes bottom flange and is threaded with flashboard, the other end is fixedly connected with bonnet by bearing pin, be provided with magnetic locking mechanism between described bottom flange and the bonnet, described unlatching key is provided with for the release mechanism of removing magnetic locking mechanism, the bottom that described body cavity contacts with the flashboard sealing is smooth circumferential surface, and described flashboard outer side covers has an elastic outer layer.
Further improvedly be: described magnetic lock mechanism is upper lockhole and the lower lockhole that has mutual corresponding setting at bonnet and the end face wall body between the bottom flange, be provided with lower magnetic steel between described upper lockhole and the lower lockhole, the below that is positioned at lower magnetic steel in the described lower lockhole also is provided with Returnning spring, described release mechanism is to be located to open the upper magnetic steel corresponding with described lower magnetic steel position on the key, and a upper magnetic steel end polarity identical setting corresponding with lower magnetic steel.
By adopting the aforementioned techniques scheme, the beneficial effects of the utility model are: the setting encryption gate valve of this novel elastic, the bottom of described valve body inside circumference fluid passage is smooth circumferential surface, the sealing surface that cooperates with flashboard is without depression, adopt the plain base valve pocket identical with water pipe, make dirt be difficult for deposition, seal more reliable; Described flashboard outer side covers has an elastic outer layer, when the flashboard traling, micro-deformation occurs compensating action is played in sealing in its elastic outer layer under the effect of pretightening force, thereby flashboard and valve body madial wall are tightly fitted, line fluid is ended fully, good sealing effect really reaches the effect without water clock.
