Abstract
The utility model discloses a kind of gate valve structures, the valve rod that it includes valve body, the flap for being respectively provided at the valve inner and top and valve deck, connect with the flap, T-type groove is equipped at the top of flap, the square head portion of valve rod is embedded in the T-type groove at the top of flap, to realize the connection of valve rod and flap.The contact area between valve rod head and flap can be significantly increased in the gate valve structure of the utility model, to greatly increase the load ability on valve rod head, be deformed valve rod head will not in extruding, the shear action for bearing valve rod axial force, efficiently avoid because between valve rod and flap contact surface too it is small cause valve rod leading edge deformation due to caused by gate valve Problem of Failure, and without the size for increasing flap and valve deck, moreover it is possible to play the role of saving gate valve manufacturing cost.
Description
Technical field
The utility model relates to a kind of gate valve structures, are the gate valve knot of square structure more particularly, to a kind of valve rod head
Structure.
Background technique
Currently, the existing valve rod applied to Wedge Gate Valves, arched with the contact surface of flap, contact area only has valve
A quarter of club head or so.When gate valve be applied to high temperature or high pressure operating condition when, valve rod head load ability reduce at double or
Valve rod axial force is multiplied, and valve rod head is squeezed with valve flap contacts position, stretches and is deformed, and causes valve invalidation.
If making valve rod head indeformable at this time, to prevent valve invalidation, it is necessary to thickening valve rod head, but this will lead to flap and valve deck
Size is increase accordingly, to cause being significantly increased for valve manufacture cost.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of gate valve structure, which can be significantly increased valve
Contact area between club head and flap makes valve rod head bear valve to greatly increase the load ability on valve rod head
It will not be deformed, be efficiently avoided because contact surface is too small between valve rod and flap when the extruding of bar axial force, shear action
Cause valve rod leading edge deformation and caused by gate valve Problem of Failure, and without the size for increasing flap and valve deck, moreover it is possible to play
Save the effect of gate valve manufacturing cost.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of gate valve structure, including valve body, difference
It is located at the flap and valve deck, the valve rod that connect with the flap of the valve inner and top, phase at the top of the valve rod and flap
The valve rod head of connection is square structure.
Further, it is equipped with T-type groove at the top of the flap, the square valve club head of the valve rod is embedded at the top of flap
In T-type groove, to realize the connection of valve rod and flap.
Further, the flap is wedge-shaped flap.
Further, the square valve club head of the valve rod is cuboid valve rod head.
The beneficial effects of the utility model are: the Wedge Gate Valves structure of the utility model is by the way that its valve rod head to be designed as
The square structure of cuboid can make valve rod head and valve after in T-type groove cuboid head being embedded at the top of flap
Contact area between valve is significantly increased, when Wedge Gate Valves is applied to high temperature and high pressure condition, in the feelings of identical stem diameter
Under condition, the contact area between valve rod head and flap will double it is above, so as to which holding for valve rod head is significantly increased
Power ability, and then be deformed valve rod head will not in extruding, the shear action for bearing valve rod axial force, it effectively prevents
Because between valve rod and flap contact surface too it is small cause valve rod leading edge deformation due to caused by gate valve Problem of Failure, and at this time without
Increase the size of flap and valve deck, moreover it is possible to play the role of saving gate valve manufacturing cost.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model gate valve structure；
Fig. 2 is the structural schematic diagram of square valve club head；
In the figure, it is marked as 1- valve body, 2- flap, 3- valve deck, 4- valve rod, 5- valve rod head.
Specific embodiment
The present invention will be further described with reference to the accompanying drawings and examples.
As depicted in figs. 1 and 2, the gate valve structure of the utility model include valve body 1, be respectively provided at 1 inside of the valve body and
The wedge-shaped flap 2 and valve deck 3 at top, the valve rod 4 connecting with the flap 2 are equipped with T-type groove, the valve at the top of the flap 2
The valve rod head 5 of bar 4 is cuboid valve rod head, and size is identical as the T-type groove, and valve rod 4 passes through its cuboid
Shape valve rod head 5 is embedded in the T-type groove at 2 top of flap, to realize the connection of valve rod 4 Yu flap 2.
The Wedge Gate Valves structure of the utility model works as handle by the way that its valve rod head to be designed as to the square structure of cuboid
After cuboid valve rod head is embedded in the T-type groove at the top of flap Nei, the contact area between valve rod head and flap can be made
It is significantly increased, when Wedge Gate Valves is applied to high temperature and high pressure condition, in the case where identical stem diameter, valve rod head and valve
Contact area between valve will double above, so as to which the load ability on valve rod head is significantly increased, and then make valve rod
Head will not be deformed when bearing the extruding of valve rod axial force, shear action, be effectively prevented because between valve rod and flap
Contact surface too it is small cause valve rod leading edge deformation and caused by gate valve Problem of Failure, and at this time without increasing flap and valve deck
Size, moreover it is possible to play the role of saving gate valve manufacturing cost.
It should be understood that the above-mentioned specific embodiment of the utility model is used only for exemplary illustration or explains this reality
With novel principle, without constituting limitations of the present invention.Therefore, in the spirit and scope without departing from the utility model
In the case of any modification, the equivalent replacement etc. made, should be included within the scope of protection of this utility model.
