Description

TECHNICAL FIELD

[0001] The utility model relates to industrial grade butterfly valve technical field, concretely is an industrial grade butterfly valve easy to stack. BACKGROUND

[0002] The butterfly valve is a simple structure regulating valve, which can be used for on-off control of low-pressure pipeline medium. The butterfly valve is a kind of valve, whose closing part (valve disc or butterfly plate) is a disc, which rotates around the valve shaft to achieve opening and closing. It mainly plays the role of cutting off and throttling on the pipeline. The butterfly valve opening and closing part is a disc-shaped butterfly plate, which rotates around its own axis in the valve body to achieve the purpose of opening, closing or adjusting. The worm reducer is adopted, which not only enables the butterfly plate to have self-locking capability, so that the butterfly plate can stop at any position, but also improves the operation performance of the valve. After the butterfly valve is processed and manufactured, it needs to be stored. However, the common butterfly valve on the market usually lacks the structure of auxiliary stacking, so that it can only be placed on the ground in single layer when stored, which occupies a lot of space, and it is also difficult to maintain stability during storage, which is easy to tip over and cause wear and tear. Therefore, we propose an industrial grade butterfly valve easy to stack, which solves the problems of insufficient stability and inconvenience of stacking of conventional butterfly valves, saves production storage space and improves economic benefits.

[0003] The utility model discloses an industrial butterfly valve, including butterfly valve body, connecting pipe, installation pipe and flange, connecting pipe symmetry sets up at butterfly valve body both ends, is provided with the installation section on connecting pipe, is detachably connected with the fixed plate that presents the arc on the installation section, is provided with the first subsiding groove on the installation section, installation pipe sets up in the first subsiding groove, and is provided with first filter screen and second filter screen at both ends, second filter screen sets up at the end away from butterfly valve body of installation pipe, is seted up on second filter screen and is used for the feed inlet for the impurity to enter the installation pipe, and the impurity filtering collection cavity is formed between installation pipe and first filter screen and second filter screen, flange is coaxial with connecting pipe and is used for connecting butterfly valve and pipeline. The industrial butterfly valve of the utility model has simple structure, is convenient to use, can effectively filter and collect impurities, is convenient for cleaning the valve body, reduces the probability of butterfly valve blockage, and further improves the service life of butterfly valve. But the butterfly valve in production, the storage occupies the space greatly, is inconvenient to stack, therefore, we propose an industrial grade butterfly valve easy to stack, which solves the problem of inconvenient stacking, saves storage space and improves production efficiency. SUMMARY

[0004] The utility model discloses an industrial grade butterfly valve easy to stack, which solves the problem of insufficient stability and inconvenience of stacking of the butterfly valve in the background art.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme:

[0006] An industrial butterfly valve easy to stack, comprising a butterfly valve body, flange joints are arranged at both ends of the butterfly valve body, a limiting block is welded outside one end of the flange joint, and a protective pad is pasted on the outer surface of the other end of the flange joint.

[0007] Preferably, the limiting block is provided with four, and the four limiting blocks are uniformly arranged on the outer wall of the flange joint in an array mode with the center of the flange joint as a base point.

[0008] Preferably, the butterfly valve body comprises a valve body, a valve seat is fixedly arranged inside the valve body, a butterfly valve plate is installed inside the valve seat, a valve rod is fixedly connected to the butterfly valve plate, and a handle is fixedly arranged at the top end of the valve rod.

[0009] Preferably, one end of the limiting block is flush with the end face of the side of the flange joint close to the valve rod, and the other end of the limiting block extends to the side of the flange joint away from the valve rod, and the extension length of the limiting block is 1.5 times the thickness of the flange joint.

[0010] Preferably, the protective pad is made of any one of neoprene, silicone rubber, nitrile rubber or natural rubber.

[0011] Preferably, one end of the protective pad pasted on the flange joint can be embedded in one end of the limiting block.

[0012] Compared with the prior art, the butterfly valve has the following beneficial effects:

[0013] 1. When the butterfly valve is stacked, the staff can first place the flange joint end with the protective pad downward on the ground or a turnover tray, then when the second layer is stacked, the flange joint with the protective pad is still downward, and the end is embedded in one end of the limiting block, because the length of the limiting block is 1.5 times the thickness of the flange joint, therefore, when stacking, the flange joint has the effects of guiding, limiting and anti-slip, thereby improving the convenience and stability of the stacking operation, avoiding the problem of sliding and falling of the upper butterfly valve, saving the storage space of the butterfly valve, improving the space utilization rate of the production workshop, and further improving the production efficiency of the butterfly valve.

[0014] 2. The industrial butterfly valve easy to stack avoids the problem of wear of the end face of the flange joint during stacking through the protective pad arranged on the flange joint, and guarantees the integrity of the main body of the butterfly valve. The butterfly valve structure can realize convenient stacking of the butterfly valve through simple structure design, the process is simple and easy to realize, and the construction cost is low.
