Description
Technical field
The utility model is related to a kind of gate valves, more particularly, to a kind of novel corrosion resistant gate valve.
Background technology
Gate valve is the conducting or stopping by opening and closing fluid in flashboard control pipeline, the direction of motion and flow direction of flashboard
It is mutually perpendicular to, when opening and closing flashboard, is rotated by handwheel so that valve rod moves up and down, the valve rod of existing gate valve directly connects with valve deck
It touches so that valve rod and valve deck serious wear, the fluid in valve are easier to chemically react with abrading section so that valve appearance
It is easily corroded, service life reduces.
Utility model content
The purpose of this utility model is to provide a kind of novel corrosion resistant gate valve, is provided with the polyformaldehyde sealing lubrication and is cased with
The valve rod and the valve deck has been isolated in effect, avoids valve deck described in the stem wear so that the valve rod and the valve
Lid is not perishable, improves the service life of gate valve.
To achieve the above object, the utility model provide a kind of novel corrosion resistant gate valve include valve body and with the valve body
The valve deck being fixedly connected is provided with flashboard and valve rod in the valve body, and described valve rod one end is fixedly connected with the flashboard, described
The valve rod other end passes through the valve deck top and is connected with operation handwheel, and the part that the valve rod is in the valve deck top is arranged
Have a polyformaldehyde sealing lubrication set, polyformaldehyde sealing lubrication set upper side is provided with gland, the gland set upper end be provided with it is anti-
Dirt lid, the dustproof cover top are concordant with the valve deck.
Preferably, the polyformaldehyde sealing lubrication puts on that setting is fluted, and there are two groove settings, in the groove
It is arranged with rubber seal.
Preferably, it is provided with card mat between the valve deck inner via hole and polyformaldehyde sealing lubrication set.
Preferably, the gland and the dustproof cover be arranged on the valve rod, the gland and the valve deck inner wall
It is threadedly coupled.
Preferably, the valve body is bolted to connection with the valve deck, the junction of the valve body and the valve deck
It is provided with gasket.
Therefore, a kind of novel corrosion resistant gate valve described in the utility model is provided with the polyformaldehyde sealing lubrication and is cased with
The valve rod and the valve deck has been isolated in effect, avoids valve deck described in the stem wear so that the valve rod and the valve
Lid is not perishable, improves the service life of gate valve；The gland is set to inside the valve deck simultaneously, reduces exposure,
Seal is increased, while increasing concentricity between valve rod, flashboard, valve body and valve deck, reduces the operation torque of valve rod.
Below by drawings and examples, the technical solution of the utility model is described in further detail.

Specific implementation mode
Embodiment
Fig. 1 is a kind of novel corrosion resistant gate valve structure schematic diagram of the utility model, and Fig. 2 is the utility model traditional gate valve knot
Structure schematic diagram, as shown in Figs. 1-2, a kind of novel corrosion resistant gate valve includes valve body 1 and the valve deck being fixedly connected with valve body 12, valve body
Flashboard 10 and valve rod 9 are provided in 1,9 one end of valve rod is fixedly connected with flashboard 10, and 9 other end of valve rod passes through 2 top of valve deck and company
It is connected to operation handwheel 3, the part that valve rod 9 is in 2 top of valve deck is arranged with polyformaldehyde sealing lubrication set 6, polyformaldehyde sealing lubrication
It covers 6 upper ends and is provided with gland 5, gland 5 sets upper end and is provided with dustproof cover 4, and 4 top of dustproof cover is concordant with valve deck 2, gland 5 and anti-
Dirt lid 4 is arranged on valve rod 9, and gland 5 is connect with 2 inner thread of valve deck, and gland 5 is set to inside valve deck 2, reduces exposure
Face, while increasing concentricity between valve rod 9, flashboard 10, valve body 1 and valve deck 2, reduce the operation torque of valve rod 9.Lead in valve deck 2
It is provided with card mat 8 between hole and polyformaldehyde sealing lubrication set 6 so that polyformaldehyde sealing lubrication set 6 is fixed on 2 upper end of the valve deck
Inside, polyformaldehyde sealing lubrication set 6 on be arranged it is fluted, groove setting there are two, rubber seal 7 is arranged in groove.It is poly-
Formaldehyde sealing lubrication set 6 is isolated by valve rod 9 with valve deck 2, reduces the abrasion between internal metal parts, while increasing valve
The leakproofness of door.Valve body 1 is bolted to connection with valve deck 2, and valve body 1 and the junction of valve deck 2 are provided with gasket 11, carry
The leakproofness of high valve body 1 and valve deck 2.
Therefore, a kind of novel corrosion resistant gate valve of the utility model is provided with the effectively isolation of polyformaldehyde sealing lubrication set 6
