Description

Big flashboard that floats

Technical Field

The utility model relates to the technical field of valves, specifically be a flashboard greatly floats.

Background

In pipelines with granular mortar, dry ash and corrosive enterprises in industries such as power plants, mines, metallurgy, chemical engineering and the like, a gate valve is used for controlling and opening and closing medium flow, the structural forms of a valve seat, a sealing surface and a gate plate directly influence the quality and the service life of the valve, and the gate plate is an important part in the gate valve.

The existing flashboard on the market is usually of an integral structure, can not realize large floating in the sealing direction any more, is beneficial to sealing a valve, and has higher cost, so that the technology capable of improving the structure of the flashboard is urgently needed on the market to perfect the equipment.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a flashboard greatly floats to solve the flashboard of this kind on the present market that above-mentioned background art provided and can not realize big floating in the sealed direction again, also do benefit to valve seal, the higher problem of cost.

In order to achieve the above object, the utility model provides a following technical scheme: a large floating gate comprising a gate; the hydraulic support comprises a fluid through hole, a flashboard T-shaped groove connecting part, a nut groove, a long T-shaped groove and threads, wherein the flashboard T-shaped groove connecting part is fixedly connected with one end of a flashboard, the nut groove is formed between the flashboard T-shaped groove connecting parts, a nut is fixedly connected in the nut groove, and the nut is provided with the threads.

Preferably, the gate plate and the fixed plate are of an integral structure.

Preferably, the nut groove and the nut are both T-shaped.

Preferably, the thread is a modified thread button, and the thread can float radially.

Compared with the prior art, the beneficial effects of the utility model are that: this big flashboard that floats:

the gate plate in the device is composed of a nut and a valve plate together, the valve plate is provided with a T-shaped notch, the shape of the T-shaped nut is T-shaped, the T-shaped nut is arranged at the T-shaped notch in the design of the valve plate, after the valve is closed, fluid in the valve acts on the blind surface of the valve plate, the valve plate is connected with the T-shaped nut (the T-shaped nut is connected with a valve rod, and the position of the valve rod is fixed), in order to achieve the sealing purpose, the valve plate is tightly attached to a valve seat to form sealing, the gate plate and the T-shaped nut are combined pieces, large floating can be achieved in the sealing direction, the valve sealing is facilitated, a hole (transverse) for bearing the valve rod is not formed in the valve plate, the thickness of the valve plate can be.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: the utility model provides a big flashboard that floats, includes flashboard 1, fluid through-hole 2, fixed plate flashboard T type groove connecting portion 3, nut groove 4, nut 5 and screw thread 6, a valve plate body 2 is seted up to one side surface of flashboard 1, the one end fixedly connected with fixed plate 3 of flashboard 1, structure as an organic whole between flashboard 1 and the fixed plate 3, it is horizontal not to open the hole of accepting the valve rod on the valve plate 1, and at the valve plate 1 of the same operating pressure and specification, can reduce valve plate 1 thickness, reduces valve plate 1 cost, form nut groove 4 between the fixed plate 3, be "T" shape between nut groove 4 and the nut 5, fixedly connected with nut 5 in the nut groove 4, flashboard 1 is the sub-assembly with the nut 5 of T shape, can realize big float in sealed direction, do benefit to valve seal, be provided with screw thread 6 on the nut 5, screw thread 6.

The working principle is as follows: when the large floating gate plate is used, firstly, a user needs to simply know the large floating gate plate, the user places the device at a designated position, the gate plate 1 is connected to a gate valve, then the nut 5 is fixed in the nut groove 4 formed by the fixing plate 3, after the valve is closed, fluid in the valve acts on a blind surface of the valve plate, the valve plate 1 is connected with the T-shaped nut 5, the T-shaped nut 5 is connected with a valve rod, and due to the fixed position of the valve rod, the valve plate 1 needs to be tightly attached to a valve seat to form sealing, the gate plate 1 and the T-shaped nut 5 are combined parts, large floating in the sealing direction can be realized to facilitate the sealing of the valve, and the content which is not described in detail in the description belongs to the prior art known by a person skilled in the art.
