Description
Technical field
The utility model is related to a kind of control valve, especially a kind of gate valve.
Background technology
Gate valve is widely used in the circulation and cut-off of the media such as liquid, gas, dust.The opening and closing element of gate valve is valve plate, valve
The direction of motion of plate and flow direction are perpendicular, to achieve the purpose that opening and closing gate valve.
Most of gate valve makes valve rod move up and down in guide groove, valve plate is pressed to by rotating the handwheel being connect with valve rod
Valve seat, to achieve the purpose that opening and closing gate valve.The left and right ends of valve plate are equipped with sealing surface, in order to keep leakproofness, existing skill
Two sealing surfaces are usually designed to that inclined-plane, corresponding valve plate design are less than the wedge shape of upper surface at lower face in art, although one
Determine to improve the sealing effect of gate valve in degree, but in use, it often collides, rub between sealing surface of valve plate, very
Easily cause abrasion and scratch, it is difficult to keep the leakproofness between valve plate and valve seat, and repair relatively difficult, thus cause
The service life of gate valve is shorter.
Utility model content
In view of this, the main purpose of the utility model is to provide a kind of sealing surfaces to be not easy to abrade, can guarantee leakproofness
And gate valve with long service life.
A kind of in order to achieve the above object, the utility model provides gate valve, including valve body, valve rod, valve deck, valve seat and valve
Plate, the valve deck, which is bolted, to be arranged in body top, and the valve body top is provided with upper chamber, and the valve body lower portion is set
It is equipped with fluid channel, the valve rod penetrates through the upper chamber and valve deck and upwardly extends, and the valve rod upper end is connected with parallel hand
Wheel, the valve rod lower end are fixedly connected with the valve plate, and the valve plate is arranged in the middle part of the fluid channel, the valve seat setting
The left and right sides in the fluid channel and positioned at the valve plate, the symmetrical wedge shape of the valve plate, and the valve plate
Lower face be less than upper surface, sealing surface is equipped at left and right sides of the valve plate, the sealing surface is equipped with upper and lower two sealings,
The sealing is arc surface, and the valve seat is equipped with and the matched lug boss of the sealing.
Preferably, the sealing protrudes from the sealing surface.
Preferably, the lug boss is inclined-plane.
Preferably, upper and lower two sealings are separately positioned on the both sides up and down of the fluid channel.
The gate valve of the utility model, by the way that sealing is arranged to arc surface, solve it is easy to wear during use and
The problem of scratch, ensures the leakproofness that gate valve is used for a long time, also improves the service life of gate valve.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model gate valve；
Fig. 2 is the enlarged structure schematic diagram at A in Fig. 1；
Fig. 3 is the enlarged structure schematic diagram at B in Fig. 1.
Specific implementation mode
It is new below in conjunction with this practicality to keep the purpose, technical scheme and advantage of the utility model embodiment clearer
Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
The embodiments of the present invention are described below in detail, the example of embodiment is shown in the accompanying drawings, wherein from beginning to end
Same or similar label indicates same or similar element or element with the same or similar functions.Below with reference to attached
The embodiment of figure description is exemplary, it is intended to for explaining the utility model, and should not be understood as the limit to the utility model
System.
As shown in Figure 1 to Figure 3, the gate valve of the utility model, including valve body 1, valve rod 2, valve deck 3, valve seat 4 and valve plate 5, valve
Lid 3, which is bolted, to be arranged at the top of valve body 1, and 1 top of valve body is provided with upper chamber 10, and 1 lower part of valve body is provided with fluid
Channel 11, valve rod 2 penetrate through upper chamber 10 and valve deck 3 and upwardly extend, and 2 upper end of valve rod is connected with parallel handwheel 6,2 lower end of valve rod
It is fixedly connected with valve plate 5.
The setting of valve plate 5 is arranged in fluid channel 11 in 11 middle part of fluid channel, valve seat 4 and positioned at the left and right two of valve plate 5
Side, the symmetrical wedge shape of valve plate 5, and the lower face of valve plate 5 are less than upper surface, and the left and right sides of valve plate 5 is equipped with sealing
Face 50, sealing surface 50 are equipped with upper and lower two sealings 51, and upper and lower two sealings 51 are located at up and down the two of fluid channel 11
Side.Sealing 51 protrudes from the setting of sealing surface 51, and sealing 51 is arc surface, and valve seat 4 is equipped with and is matched with sealing 51
Lug boss 41, lug boss 41 be inclined-plane.Because gate valve is made of hard alloy, by setting sealing 51 to arc surface,
Make it with the contact of 4 lug boss 41 of valve seat than milder, using process it is not easy to wear and scratch.
It can be seen that the gate valve of the utility model solves appearance during use by the way that sealing is arranged to arc surface
The problem of easy to wear and scratch, ensures the leakproofness that gate valve is used for a long time, also improves the service life of gate valve.
The above, the only preferred embodiment of the utility model, are not intended to limit the protection of the utility model
Range.
