Description
Technical field
The utility model is related to a kind of valve, specifically, and it is related to a kind of gate valve.
Background technology
Gate valve is an opening and closing element flashboard, and the direction of motion and flow direction of flashboard are perpendicular, so as to reach opening and closing gate valve
Purpose, traditional gate valve includes the valve body containing fluid passage, the wherein valve rod for opening and closing fluid passage, valve body
One end be located at valve body in, the other end be located at valve body outside, and valve body be located at valve body outside one end be provided with handwheel, by rotating hand
Take turns to make valve body move up and down, so as to reach the purpose of opening and closing gate valve.
But be due to that valve rod is made up of metal material, valve rod be again long period of soaking in water, therefore valve rod makes
Corrosion phenomenon is highly susceptible to during.For this problem, Application No. 201610179621.X Chinese patent, its
A kind of gate valve, including the valve body with fluid passage and one end are located at the valve rod in valve body, and valve rod, which is provided with, is used for block fluid
The air bag of passage and the gas passage communicated with inside air bag, one end of gas passage protrude from one end of valve body through valve rod,
When needing to close on gate valve, by being inflated toward in gas passage, the gas in gas passage can enter inside air bag,
So as to reach the purpose to airbag aeration, and after air bag expands to a certain extent, circulation passage can be blocked gate valve by air bag
Gate valve is opened and closed caused by getting rusty.
It is difficult.
The content of the invention
Goal of the invention：The problem of in order to overcome conventional generation, the utility model provides a kind of gate valve.
Technical scheme：The utility model discloses a kind of gate valve, including the literary stud of valve body, valve seat, flashboard, valve rod, full spiral shell, on
Seal receptacle, gland, pressing plate, eyelet bolt, valve stem nut, handwheel, locking nut, the valve body are provided with valve seat, the valve seat
It is connected with flashboard, the flashboard is connected by valve rod with bottom sealing socket, the bottom sealing socket passes through the literary spiral shell of full spiral shell with upper seal support
Post is connected, and the bottom of the bottom sealing socket be connected with metal wound gasket, provided with gland at the top of the upper seal support, the gland and
Pressing plate is connected, and the pressing plate is connected with eyelet bolt, and the upper seal support is connected with valve rod, and the valve rod is connected with lubricating cup, institute
State lubricating cup bottom to be fixed by valve stem nut, the lubricating cup upper end is connected with handwheel, the handwheel is with valve rod junction by locking screw
Mother is fixed, the gate valve nominal pressure 1.6-16bar, water density 1.8-18kg/m, using japanning, this practicality inside the gate valve
New water density is strong, and inside is difficult to get rusty.
