Abstract
The utility model discloses a limit structure for a butterfly valve and a butterfly plate. The limit structure includes a valve body and a valve rod, wherein an inflow port and an outflow port are arranged on the two sides of the valve body respectively; the butterfly plate is fixedly installed on the valve rod; strengthening ribs are distributed on the butterfly plate; the butterfly plate is positioned in the valve body and mutually matched with a sealing valve seat in the valve body; the sealing valve seat is fixedly installed on the inner wall of the valve body; a first limiting plate and a second limiting plate are also arranged on the inner wall of the valve body; when the butterfly plate is opened, the first limiting plate is positioned on one side at the upstream of a flow passage; and when the butterfly plate is opened, the second limiting plate is positioned on one side at the downstream of the flow passage. The limit structure has a simple structure, is convenient to install and use, solves the problems that the closing is influenced as the valve plate is heavily stressed and deformed under over high hydraulic pressure, and the like through adopting the structural design of the limiting plates, has long service life, and meets the requirement for the service life.
Description
Technical field
The utility model relates generally to a kind of butterfly valve structure, relates in particular to a kind of limit structure of butterfly valve butterfly plate.
Background technique
Butterfly valve is Flap valve again, is a kind of modulating valve simple in structure, also can be used for the switch control of low pressure pipeline medium simultaneously.Mainly be applicable in the engineering systems such as producer, coal gas, rock gas, LPG, town gas, cold and hot air, chemical industry smelting and generation environment-friendly and carry on the pipeline of various corrosivity, non-corrosive fluids medium, be used to regulate and block flowing of medium.If hydraulic pressure is excessive in the using process, the time then can cause the stressed excessive deformation of butterfly plate when longer, and influence is closed, and working life is short.
The model utility content
The purpose of the utility model is in order to remedy the deficiency of prior art, a kind of limit structure of butterfly valve butterfly plate to be provided, and has solved butterfly plate and has closed and be not easy; Excessive at hydraulic pressure, the time then can cause the stressed excessive deformation of butterfly plate when longer; Problems such as influence is closed, and working life is short.
The utility model is realized through following technological scheme:
A kind of limit structure of butterfly valve butterfly plate includes valve body and valve rod, and the both sides of said valve body are respectively equipped with inflow port, go out head piece; Be installed with butterfly plate on the said valve rod; Be distributed with stiffening rib on the said butterfly plate, said butterfly plate is positioned at valve body, and cooperatively interacts with seal valve seat in the valve body; Said seal valve seat is fixedly installed on the valve interior wall; Also be provided with first limiting board, second limiting board on the said valve interior wall, said first limiting board is positioned at a side that is in the runner upper reaches when opening, and said second limiting board is positioned at a side that is in the runner downstream when opening.
Its principle is: through the structural design of limiting board, the enable possition of butterfly plate is positioned, avoided because of the stressed excessive deformation of the excessive valve plate of hydraulic pressure, influence is closed, long service life.
The advantage of the utility model is following:
The utility model is simple in structure, easy to install, through the structural design of limiting board, has avoided because of the stressed excessive deformation of the excessive valve plate of hydraulic pressure, and influence such as closes at problem, and long service life has satisfied working life.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Referring to accompanying drawing, a kind of limit structure of butterfly valve butterfly plate includes valve body 1 and valve rod 2; The both sides of valve body 1 are respectively equipped with inflow port, go out head piece, are installed with butterfly plate 3 on the valve rod 1, are distributed with stiffening rib 4 on the butterfly plate 3; Butterfly plate 3 is positioned at valve body 2; And cooperatively interact with the seal valve seats in the valve body 2, seal valve seat is fixedly installed on valve body 2 inwalls, also is provided with first limiting board 5, second limiting board 6 on valve body 2 inwalls; Said first limiting board 5 is positioned at a side that is in the runner upper reaches when opening, and said second limiting board 6 is positioned at a side that is in the runner downstream when opening.
