Detailed Description
the present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1 and 2, the gate valve for the power station comprises a hollow valve body 1 and a valve cover 2 arranged on the valve body 1, wherein a valve seat and a valve plate 3 matched with the valve seat are arranged in the valve body 1, a valve rod 4 is vertically arranged on the valve plate 3, and the valve rod 4 penetrates through the valve cover 2 and then is located outside the valve cover 2. The outer wall of the upper end of the valve rod 4 is in threaded connection with the valve cover 2, and the upper end of the valve rod 4 is also provided with a hand wheel 41. In particular, the valve plate in the embodiment adopts a conical design, and the cross-sectional area of the end of the valve plate far away from the valve rod is smaller than that of the end of the valve plate close to the valve rod.
When the gate valve needs to be closed, the hand wheel 41 is rotated to drive the valve rod 4 to rotate downwards, the valve rod 4 drives the gate plate to synchronously rotate downwards, and the valve plate 3 is tightly sealed with the valve seat at the moment so as to close the gate valve. When the gate valve needs to be opened, the hand wheel 41 is rotated reversely, the hand wheel 41 drives the valve rod 4 to synchronously rotate and move upwards, and at the moment, the valve rod 4 drives the valve plate 3 to synchronously move upwards, so that the gate valve is opened.
As shown in fig. 3 and 4, a pair of slide grooves 11 is horizontally provided on the top wall of the valve body 1, and the pair of slide grooves 11 are located on both sides of the valve rod 4. A sliding block 12 is connected in the sliding groove 11 in a sliding manner, and springs 13 are arranged between one side of the sliding block 12 close to each other and the side wall of the sliding groove 11.
As shown in fig. 4, a support rod 14 is vertically arranged on the lower end surface of each slide block 12, a pair of cleaning rods 15 is hinged to the lower end of each support rod 14, and the two pairs of cleaning rods 15 are hinged to each other to form a closed loop around the valve plate 3 in an end-to-end manner. In order to solve the installation problem of the cleaning rod, the valve body can be decomposed in a welding instead of casting mode to form a plurality of assemblies. The machining is "fully exposed" to facilitate the installation of the cleaning rod, such as a split-machining welded gate valve with publication number CN2196221Y, which will not be described in detail herein.
As shown in fig. 4 and 5, cleaning brushes 5 are arranged on the inner walls of the side where the cleaning rods 15 are close to each other, each cleaning brush 5 comprises a brush plate 51 and bristles 52 arranged on the brush plate 51, and the bristles 52 abut against the outer wall of the valve plate 3.
As shown in fig. 5, a plurality of elastic rods 53 are further disposed on one side of the brush plate 51 close to the bristles 52, and a rubber sleeve 54 capable of increasing friction force with the shutter 3 is disposed on one end of each elastic rod 53 away from the brush plate 51.
When the valve plate 3 moves downwards, the tapered valve plate 3 moves downwards along the gaps between the cleaning rods 15 and gradually expands the cleaning rods 15, and at the moment, the cleaning rods 15 drive the connected supporting rods 14 to move towards the valve plate 3, so that the supporting rods 14 on both sides of the valve plate 3 move towards the direction of approaching each other. At the same time, the support rod 14 drives the slide block 12 to slide along the inner wall of the slide groove 11, and presses the movable spring 13 to compress. And the cleaning brush 5 on the cleaning rod 15 always props against the outer wall of the valve plate 3 at the moment, and the dirt on the surface of the valve plate 3 is scrubbed from bottom to top.
when the valve plate 3 moves upwards, the spring 13 springs open and drives the slide block 12 to move reversely, the slide block 12 drives the supporting rod 14 to move synchronously and reversely, and the cleaning rods 15 are gathered together at the moment. At this time, the cleaning brush 5 on the cleaning rod 15 always props against the outer wall of the valve plate 3, and the dirt on the surface of the valve plate 3 is brushed from top to bottom.
Consequently, when valve plate 3 up-and-down reciprocating motion, the cleaning brush 5 on the cleaning rod 15 contradicts 3 outer walls of valve plate all the time to scrub the dirt on 3 surfaces of valve plate, improve the clean and tidy degree on 3 surfaces of valve plate, avoid the scale deposit phenomenon to appear on 3 surfaces of valve plate.
Because the elastic rod 53 abuts against the valve plate 3, when the valve plate 3 moves up and down, a friction force exists between the elastic rod 53 and the valve plate 3 to drive the elastic rod 3 to deviate. When the valve plate 3 is completely separated from the cleaning rod 15, the original offset part of the elastic rod 53 is restored to the initial state under the action of the elastic force of the elastic rod 53, wherein the bristles 52 are knocked by the elastic force of the elastic rod 53 under the action of inertia, so that the bristles 52 shake, and further, the scales on the bristles 52 can smoothly fall off and flow along with the medium, and the neatness of the bristles 52 is improved.
As shown in fig. 5, a pair of mounting rods 55 are disposed on a side of the brush plate 51 away from the bristles 52, a pair of mounting holes 16 for the mounting rods 55 to pass through are formed in the cleaning rod 15, and a nut 56 for pressing the outer wall of the cleaning rod 15 is screwed on the mounting rods 55.
As shown in fig. 2, the outer wall of the valve cover 2 is provided with a plurality of upper corner lugs 6, and the plurality of upper corner lugs 6 are uniformly distributed along the circumferential direction of the valve cover 2. Be provided with a plurality of confession on the valve body 1 and go up the lower angle ear 7 that the angle ear 6 contradicted respectively to go up the angle ear 6 and run through the fixed orifices 8 that have mutual intercommunication between the lower angle ear 7, it has fixed part 9 to peg graft in the fixed orifices 8, and fixed part 9 is used for being in the same place upper angle ear 6 and lower angle ear 7 are fixed, and fixed part 9 can be the fastener.
When the valve cap 2 is opened, the fixing portion 9 is released, and the valve cap 2 can be removed after the fixing portion 9 is taken out from the fixing hole 8. When installation valve gap 2, place valve gap 2 on valve body 1, rotate valve gap 2 for the last upper horn ear 6 of valve gap 2 is aligned the back completely with lower horn ear 7 on the valve body 1, pegs graft in fixed orifices 8 fixed part 9, and the realization upper horn ear 6 is fixed in the connection between lower horn ear 7, realizes the installation of valve gap 2.
The specific embodiments are only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications of the present embodiments without inventive contribution as required after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present invention.
