Description
Technical field
The utility model belongs to valve castings technical field, and in particular to a kind of corrosion-resistant valve deck.
Background technology
Currently, valve deck is equipped with the valve part of valve rod sealing member, for connecting or supporting execution component, valve deck and valve body
It can be an entirety, can also be chorista.Valve deck is exactly head cover, it is the free section of valve body sub-assembly interarea, is commonly used
High-strength bolt is connected with valve body, it is subject to the part of pressure, therefore as with the design condition of valve housing being.One
As twoport valve deck include inlet end and an outlet end, input end is generally connected with valve body, outlet end generally and be connected to pipeline and
Flange, but existing valve deck either input end or outlet end, end face is all smooth planar design, in this way, working as valve
When lid is with valve body or flanged joint, will there are problems that sliding and poor sealing.
Existing valve deck is integrally divided into two classes：One kind is common metal valve deck, although hardness height is not easily broken, by
All there is corrosivity mostly in the liquid of valve body institute water conservancy diversion, often valve deck is caused to corrode, it in the course of time will be to valve deck
Leakproofness causes serious influence；Another kind of is ceramic valve deck, although more resistant to corrosion for metal valve deck, it is strong
Degree is inadequate, and easily broken by hitting, safety is not high.
Utility model content
The purpose of this utility model is to provide a kind of corrosion-resistant valve deck, and hardness is high, corrosion-resistant, and can coordinate a variety of valve body tubes
Road uses.
The utility model provides the following technical solution：
A kind of corrosion-resistant valve deck, including the inner cap body and outer cover that are mutually clamped, the inner cap body and the outer cover it
Between be equipped with door, the interior bottom of the outer cover is equipped with erosion resistant coating, and buffer layer is equipped between the erosion resistant coating and the inner cap body,
It is additionally provided with layer of silica gel between the buffer layer and the inner cap body, baffle and connection through-hole, the company are equipped in the inner cap body
It connects through-hole wall and is equipped with anti-corrosion glued membrane.
Preferably, the door is equipped with pin, and the pin is fixed to the outer cover across the inner cap body.
Preferably, be equipped with the first sealing ring between the inner cap body and the door, the door and the outer cover it
Between be equipped with O-ring.
Preferably, the outer cover is equipped with several mounting holes.
Preferably, fixing bolt is equipped between the baffle and the inner cap body.
Preferably, the buffer layer corresponds to the position of the connection through-hole and is equipped with through-hole, described in the erosion resistant coating corresponds to
The position of through-hole is equipped with connector.
Preferably, the second sealing ring is equipped between the buffer layer and the inner cap body.
The utility model has the beneficial effects that：Inner cap body and outer cover matching design improve the applicability and structure of lid
Hardness；It is equipped with multi-layer anticorrosion structure between inner cap body and outer cover, improves the corrosion resistant erosion degree of valve deck；It is equipped between cover body structure
Sealing ring ensures the leakproofness of valve deck.
