Abstract
The utility model provides a sealing surface device for a ship gate valve. The sealing surface device comprises a valve body 1 and a valve core 2, wherein a sealing surface 3 made of a soft material is arranged at the joint of the valve body 1 and the valve core 2. As the sealing surface 3 with tetrafluoroethylene is arranged at the joint of the valve body 1 and the valve core 2, the sealing surface 3 is plastic, and the sealing surfaces 3 are of different materials when in contact with the valve core 2. When the gate valve sealing surface device for the ship is adopted, the phenomenon of easy occlusion of different materials is effectively prevented, and the occlusion of the sealing surfaces of the same material of the valve body 1 and the valve core of the valve is ensured.
Description
Technical field
The utility model relates to chemical product pipeline gate valve peculiar to vessel, relates in particular to a kind of sealing surface of the discharge gate device peculiar to vessel.
Background technique
Chemical tanker proportion in chemical transport is increasing at present; Chemical product selection for pipeline stainless steel sluice valve is more universal, and the stainless steel sluice valve bulk material has satisfied the requirement of chemical product corrosion-resistant, but spool, valve seal flooring are selected a kind of material of stainless steel simultaneously for use; In use be easy to kill under the face length time stressing conditions of two smoother; In case sealing surface is killed, valve will lose the keying function, will cause the cargo hold liquid pump not come out in case valve loses function; And the cargo tank environment is abominable, and personnel can not enter field maintenance easily.
The model utility content
The purpose of the utility model provides a kind of anticorrosion, sealed valve, the sealing surface of the discharge gate device a kind of peculiar to vessel of avoiding spool and valve body to kill mutually.
The purpose of the utility model realizes as follows: a kind of sealing surface of the discharge gate device peculiar to vessel, have valve body and spool, and described valve body and spool connection part are provided with the sealing surface of soft material.
Saying further, the sealing surface of said elastic material are tetrafluoroethylene material seal face.
Saying further: described sealing surface has two to four
The advantage of the utility model: be provided with the sealing surface of band because of tetrafluoroethylene at valve body and spool connection part, the sealing face belongs to the plastics class, with belong to two kinds of different materials when spool contacts.Effectively prevented the phenomenon that same material is killed easily, guaranteed that valve and valve core sealed cover same material kill.
Description of drawings
For content of the present invention is expressly understood more easily, below according to instantiation, and combine accompanying drawing that the present invention is done further detailed explanation, wherein:
Accompanying drawing is the structural representation of the utility model;
Embodiment:
See accompanying drawing; A kind of sealing surface of the discharge gate device peculiar to vessel has valve body 1 and spool 2, and described valve body 1 and spool 2 connection parts are provided with the sealing surface 3 of soft material; The sealing surface 3 of said soft material is a tetrafluoroethylene material seal face 3, and described sealing surface 3 has two to four.When 2 contacts of valve body 1 and spool were connected, because there is tetrafluoroethylene material seal face 3 centre, both can not kill to have avoided valve body 1 and spool 2.
Above-described instantiation; Purpose, technological scheme and beneficial effect to the utility model have carried out further explain, it should be understood that the above is merely the instantiation of the utility model; Be not limited to the utility model; All within the spirit and principle of the utility model, any modification of being made, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
Claims (3)
1. a sealing surface of the discharge gate device peculiar to vessel has valve body (1) and spool (2); It is characterized in that: described valve body (1) and spool (2) connection part are provided with the sealing surface (3) of soft material.
