Abstract
The utility model provides a gate plate and valve rod protection device of a gate valve, belonging to a protection device on the gate valve. The gate plate is connected with the valve rod, one groove is arranged on the gate plate, the other groove is arranged on the valve rod, the upper part of a corrosion-resistant flexible jacket is fixed in the groove on the valve rod by one elastic clamp ring, and the lower part is fixed in the groove on the gate plate by the other elastic clamp ring. By adopting the above structure, the protection device can protect the connection position between the gate plate and the valve rod by the corrosion-resistant flexible jacket, thus reducing even avoiding couple corrosion and bacterial corrosion on the connection position by flowing media in the valve; therefore, the service life of the valve is prolonged. Moreover, the protection device has the characteristics of simple structure and easy manufacturing.
Description
Technical field
The utility model provides a kind of protective equipment, the protective equipment on especially a kind of gate valve.
Background technique
Gate valve is a kind of of block valve.Gate valve has that flow resistance is little, structure length is short, keyings is more laborsaving, the media flow direction is unrestricted, structure is simple, be easy to plurality of advantages such as manufacturings, so has all obtained use widely at each elephant.But because flashboard and valve rod adopt different metals to make, and the joint do not have seal arrangement, and flashboard under the effect of galvanic corrosion, bacterial corrosion and mechanical force moment, forms corrosion easily, and the flashboard obscission takes place, and has shortened the working life of gate valve.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of gate valve flashboard, valve rod protective equipment, to alleviate the corrosion of flashboard, valve rod joint, the working life of raising valve.
The utility model is to realize like this, gate valve flashboard, valve rod protective equipment, it has flashboard and valve rod to link together, on fluted on the described flashboard, valve rod, another groove is arranged, corrosion-resistant flexible jacket top by elastic collar be fixed in another groove on the valve rod, the bottom is fixed in the groove on the flashboard by another elastic collar.
Adopt the protective equipment of said structure, can flashboard, valve rod joint be protected by corrosion-resistant flexible jacket, alleviate in addition the medium having avoided flowing in the valve to galvanic corrosion, the bacterial corrosion of joint, the working life of having improved valve.And simple in structure, make easily.
Description of drawings
Fig. 1 is the schematic representation of the utility model structure.
Embodiment
The embodiment who provides below in conjunction with accompanying drawing illustrates concrete structure of the present utility model.
As shown in drawings, the gate valve flashboard of the utility model, valve rod protective equipment, it has flashboard 5 and valve rod 1 to link together, on fluted on the described flashboard, valve rod, another groove is arranged, corrosion-resistant flexible jacket 7 tops by elastic collar 2 be fixed in another groove on the valve rod, the bottom is fixed in the groove on the flashboard by another elastic collar 6.
In the described corrosion-resistant flexible jacket 7 urethane foam body 3 is arranged.The material that the urethane foam body can adopt existing spray commonly used at present now to foam is made.
In the described corrosion-resistant flexible jacket 7 butter is arranged.
The existence of urethane foam body or butter can further improve the sealing of flashboard, valve rod joint, and this place is hedged off from the outer world.
Flashboard 5 can link together by T shape on the T-slot above it 8, the valve rod 4 and valve rod 1.
The device of the utility model is installed on the existing gate valve, owing to alleviated the corrosion of flashboard, valve rod joint, thus the working life of improving whole valve.
Claims (3)
1, gate valve flashboard, valve rod protective equipment, it has flashboard (5) and valve rod (1) to link together, it is characterized in that, on fluted on the described flashboard, valve rod, another groove is arranged, corrosion-resistant flexible jacket (7) top by elastic collar (2) be fixed in another groove on the valve rod, the bottom is fixed in the groove on the flashboard by another elastic collar (6).
