Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
As long as all by the protection of Patent Law in the scope of the claims of the utility model.
As shown in Figure 1, it is a kind of with aperture instruction elastic sluice valve with wedge-shaped sealing face, including valve body 1, flashboard 2, valve rod 3, valve deck 4 with
And valve seat 5.Valve seat 5 is wholely set with valve body 1.Valve rod 3 is fixedly connected in one end in 1 channel of valve body with flashboard 2, and valve rod 3 is remote
One end from flashboard 2 is provided with handwheel 6.Lubrication thrust pad 7 is provided between valve rod 3 and valve deck 4, which uses
Self-lubricating material is made, and has the function of low-friction coefficient and has valve rod 3 is anti-to fly out, so that the rotation opening and closing torque of valve rod 3
Gently.
The side of valve deck 4 is provided with the pressing plate 8 to limit to lubrication thrust pad 7, the upper surface of pressing plate 8 and soil surface
In same level, so that gate valve is located at, pressing plate 8 is below to be partly embedded into underground, and the part that gate valve is located at 8 or more pressing plate is naked
Reveal to outside.Between pressing plate 8 and valve deck 4 by the first fastener 9 carry out it is detachable be fixedly connected, between valve deck 4 and valve body 1
Detachable be fixedly connected is carried out by the second fastener 10.First fastener 9 and the second fastener 10 are in contact with soil
Position be provided with the filling member 11 to completely cut off soil.First fastener 9 and the second fastener 10 are preferably bolt.
The opening degree indicating mechanism that can determine whether 2 aperture of flashboard is provided with positioned at 8 top of pressing plate, which includes
The bracket 12 that can be fixedly connected with pressing plate 8, the surface of bracket 12 have scale and are hollow tubular structure.Bracket 12 and valve rod 3
For concentric setting.The side of valve rod 3 is threaded with feed screw nut 13, and the side of feed screw nut 13 is fixedly connected with lock
The instruction block 14 of 2 aperture of plate instruction function.The side of bracket 12 is provided with the recessing groove 15 passed through for instruction block 14, indicates block
14 two sides are abutted against with 15 inner wall of recessing groove.Particularly, the scale on bracket 12 is set to the edge of recessing groove 15
For user's recognition.The gate valve course of work of its aperture instruction is as follows: making valve rod 3 is synchronous to carry out by rotating handwheel 6
Rotation, valve rod 3 rotate during can synchronous drive feed screw nut 13 rotate.Due to being fixedly connected with feed screw nut 13
14 two sides of instruction block abutted against with recessing groove 15 so that instruction block 14 and feed screw nut 13 cannot follow valve rod 3 into
Row rotates synchronously, so that feed screw nut 13 and instruction block 14 can only be moved along the direction of axis line of valve rod 3.Indicate block
14 movement can lead to and the relative position between bracket 12 changes, to be obtained by the scale on bracket 12
2 opening value of flashboard.
As shown in Figure 1, flashboard 2 includes that there are two the first flashboard 16 and the second flashboard 17 being parallel to each other, the first flashboards
16 and second one end of flashboard 17 be fixedly connected to the same fixed plate 18, the side of fixed plate 18 and valve rod 3 is fixed connects
It connects.The first flashboard 16 and the second flashboard 17 can be driven to be moved relative to 1 axial direction of valve body simultaneously when valve rod 3 rotates
It is dynamic.By the way that flashboard 2 is separated into two designs, so that gate valve can better block media when flashboard 2 is in close state down
Flowing has double-layer seal effect.
Further, the outside of the first flashboard 16 and the second flashboard 17 is enclosed with rubber seal 19, and each rubber is close
The side of sealing 19 can be realized with 5 junction of valve seat and seal.Rubber seal 19 on the first flashboard 16 and it is located at
The side of rubber seal 19 on second flashboard 17 is fixedly connected with fixed plate 18, the other side with gate valve runner bottom wall
Squeeze forced seal.When flashboard 2 is closed, the rotation of valve rod 3 can synchronous drive the first flashboard 16 and the second flashboard 17 downwards
It is moved to and carries out pressure extruding with gate valve runner bottom wall, so that the equal stress in the two sides of rubber seal 19 is squeezed.It is solid
After the rubber seal 19 of fixed board 18 and the first flashboard 16,17 junction of the second flashboard is squeezed, promote rubber seal 19 right
The valve seat 5 at the place of abutting against exerts a force, to reinforce the sealing performance between flashboard 2 and valve seat 5；Its first flashboard 16, the second lock
After 19 stress of rubber seal that plate 17 abuts place with gate valve runner bottom wall squeezes, so that towards the rubber of gate valve runner bottom wall side
19 thickness of glue sealing element is thinning, while it can increase with the contact area of gate valve runner bottom wall, and then reinforce close at its abutting
Sealing property.When flashboard 2 is opened, the rubber seal 19 in compressive state restores rapidly to original state, due to material originally
The elastic principle for expecting itself only needs extremely light torque when flashboard 2 opens and closes.
Further, each rubber seal 19 include the sealing lip 20 abutted against with valve seat 5 and with flowed in valve
The sealing surface 21 that dynamic medium is in contact.Junction between sealing lip 20 and sealing surface 21 is provided with the cambered surface 22 to concave, should
Cambered surface 22 is first medium stress surface.When flashboard 2 is closed so that medium fills in the runner for being located at 2 side of flashboard, due to
First medium stress surface is cambered surface 22, so that medium may make first medium stress surface to carry out stress when impacting to cambered surface 22,
So that sealing lip 20 is squeezed and reinforces carrying out forced seal with 5 junction of valve seat, to improve sealing damper 2 and valve seat
Sealing performance between 5.
Further, each rubber seal 19 be provided with notch 23 towards the side of gate valve runner bottom wall, two
23 opening direction of notch mutually deviates from setting and towards medium direction of flow.The notch 23 is second medium stress surface.When flashboard 2
When closing so that medium fills in the runner for being located at 2 side of flashboard, since second medium face is a notch 23, so that medium exists
Second medium stress surface may make to carry out stress when impacting to notch 23, so that being located at gate valve runner bottom wall side
Rubber seal 19 is squeezed and reinforces carrying out forced seal with gate valve runner bottom wall junction, is being closed with improving flashboard 2
When to medium stop performance, to improve gate valve overall sealing performance.
