Technical Field
The utility model relates to a valve, in particular to a combined butterfly valve structure.
Background
Butterfly valves, also known as flaps, can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal, and radioactive media. The pipe is mainly used for cutting and throttling. The existing butterfly valve is usually a disc-shaped butterfly plate which rotates around the axis of the butterfly valve in a valve seat, so that the purpose of opening and closing or adjusting is achieved. The inventor of the utility model finds that the sealing performance of the butterfly valve is poor after the butterfly valve is arranged between the adjacent sections of water pipes, and after the water is intercepted, the water can flow to another section of pipeline from the gap between the butterfly plate gaps of the butterfly valve, so that the intercepting effect is poor; moreover, once the butterfly plate of the butterfly valve fails and cannot be completely turned off or other faults occur, the butterfly valve needs to be disassembled for maintenance, so that the whole working process is influenced, and the working efficiency is greatly reduced. Accordingly, there is a need for a new valve structure to solve the above problems.

Drawings
Fig. 1 is a schematic structural view of an embodiment of the present utility model.
The attached drawings are used for identifying and describing:
1. a butterfly valve body; 2. a gate valve; 3. a flange; 4. and (5) inserting plates.
Detailed Description
The utility model will be described in further detail with reference to the drawings and the specific examples.
As shown in fig. 1: the utility model provides a combination formula butterfly valve structure, includes butterfly valve main part 1, butterfly valve main part 1's both ends are connected with push-pull valve 2, and butterfly valve main part 1 and two push-pull valve 2 level are arranged, and push-pull valve 2 is connected with butterfly valve main part 1 detachable.
Specifically, the butterfly valve body 1 and the gate valve 2 of the present embodiment are both manual valves. The butterfly valve main body 1 and the two gate valves 2 are arranged in a straight line, the two ends of the gate valve 2 are provided with flanges 3, the flange 3 at one end is connected with the butterfly valve main body 1, namely, the two ends of the butterfly valve main body are also provided with flanges, and the butterfly valve main body is respectively in flange connection with the two gate valves. The flange 3 at the other end of the gate valve is connected with a water pipe, namely, the connecting end of the water pipe is provided with a flange which is connected with the gate valve in a flange way. All flanges are matched flanges, and the sizes of the flanges are correspondingly arranged.
In this embodiment, the gate valve is connected to both sides of the butterfly valve main body, because only the butterfly valve is connected between the water pipes, water flows out from the slit of the butterfly plate of the butterfly valve and cannot be completely sealed, and the gate valve is added, so that a second seal can be formed, and the sealing performance is greatly improved.
In this embodiment, butterfly valve main part 1 adopts flange formula butterfly valve, and dismouting safety is convenient, and this embodiment is on the basis that need not change butterfly valve main part structure, only needs to improve the leakproofness of butterfly valve main part through flange joint push-pull valve, simple structure, low cost, easily reforms transform.
In this embodiment, the gate valve 2 adopts an ultrathin knife gate valve, and has the following advantages: (1) light weight: the ultrathin knife gate valve has small volume, small flow resistance and light weight, and the weight is reduced by about 20-30 percent compared with the weight of the traditional gate valve, so that the installation and the maintenance are convenient; (2) The sealing performance is good, leakage is stopped to the greatest extent, and the sealing surface has high corrosion resistance and good wear resistance, so that the service life of the valve is long.
In this embodiment, when butterfly valve main part 1 is under the prerequisite that both ends push-pull valve 2 closed, can independently dismantle, convenient maintenance. The butterfly valve main part, push-pull valve all can independently open and close, when the condition that butterfly valve main part 1 breaks down and can't turn off completely, can close both ends push-pull valve 2, also can cut off the pipeline completely this moment, consequently, this integrated configuration of this embodiment is except improving the leakproofness, still can realize the function of closure under the condition that butterfly plate trouble appears in the butterfly valve main part.
The working principle of the embodiment is as follows: the flange 3 of one end of each gate valve 2 is in threaded connection with the flange of the butterfly valve main body 1, the flange of the other end of each gate valve is in threaded connection with the flange of the water pipe, the butterfly valve main body 1, the gate valve 2 and the water pipe are connected into a whole, and the butterfly valve main bodies 1 and the gate valve 2 are arranged in a straight line so as to be convenient to install. The water pipe of this embodiment is big pipe diameter water pipe, and water flow is great, and all can set up the combination butterfly valve of this embodiment between the multistage water pipe. When the interception is needed, the butterfly valve body 1 and the gate valve 2 are manually closed; the valve on the butterfly valve main body 1 is a rotary butterfly plate, and is rotated around the axis of the valve seat in the valve seat to be opened and closed; the flashboard 4 on the flashboard valve 2 moves perpendicular to the center line of the valve seat, and the butterfly plate and the flashboard 4 are closed to cut off the flow of water, so that even if the butterfly plate side of the butterfly valve main body is not sealed enough, the water can flow from the gap of the butterfly plate to the flashboard valve side, but the water still can be prevented from flowing from the water pipe on one side to the water pipe on the other side through the two seals of the flashboard valve, thereby greatly improving the tightness. And even if the butterfly plate of the butterfly valve main body fails and can not be completely shut off, the butterfly valve can also be sealed through the gate valve 2 to realize closure. When the interception is not needed, the butterfly plate and the plugboard are opened to enable water flow to pass through. In addition, when the butterfly valve main body breaks down and needs to be overhauled in the shutoff process, the butterfly valve main body is disassembled and overhauled only by ensuring that the gate valves on two sides are in a closed state, and the gate valves can still shutoff without affecting the whole working process, so that the working efficiency is greatly improved.
In summary, on one hand, two ends of the butterfly valve main body are connected with the gate valve to form two seals, so that the problem of water leakage caused by the fact that the butterfly valve is arranged between water pipes independently in the prior art is solved, the sealing performance is greatly improved, and even if the butterfly valve main body malfunctions and needs to be maintained or a butterfly plate of the butterfly valve main body cannot be completely closed, the whole working process is not influenced, and only the butterfly valve is required to be disassembled for maintenance, the gate valve can still cut off; on the other hand, the flange type butterfly valve is selected, so that the disassembly and assembly are safe and convenient, the main structure of the butterfly valve does not need to be changed, the tightness of the main body of the butterfly valve can be improved only by connecting the gate valve through the flange, and the butterfly valve is simple in structure, low in cost and easy to reconstruct; furthermore, the gate valve is matched with the butterfly valve main body by adopting the ultrathin knife gate valve, so that the butterfly valve is light in weight, convenient to assemble and disassemble, good in sealing performance and capable of avoiding leakage to the greatest extent.
