Abstract
The utility model relates to a gate valve for a hot oil-production well head, which is composed of a hand wheel 1, a screw nut 2, a valve rod 4, a support bracket 3, a valve cover 5, a valve seat 6, a gate plate 7 and a valve body 8. The utility model is characterized in that three sealing sections and a stainless steel sleeve 81 are cast in the valve body 8. Thus, the sealing is reliable, and a sealing ring with pressure can be changed. The utility model has the advantages of high temperature resistance, corrosion resistance and low cost, and can be used for various well heads of hot production.
Description
The utility model relates to a kind of wellhead assembly gate valve.
China began thermal recovery well head device is studied at the beginning of the eighties, had formed specialized production capacity by 1985, and the structure of its critical component gate valve is two dull and stereotyped expansive valves, its novel structure, and sealing is reliable, corrosion-and high-temp-resistant.But complex structure, size is bigger than normal, cost is high.
The purpose of this utility model provide a kind of simple in structure, function is many, easy to operate, cost is low, the novel gate valve of corrosion-and high-temp-resistant.
Structural representation when accompanying drawing 1 is the utility model shutoff.
Structural representation when accompanying drawing 2 is the utility model unlatching.
Accompanying drawing 3 is structural representations of valve rod 4 in the utility model, flashboard 7, pin 11.
The utility model provides (referring to accompanying drawing 1,2,3) with following embodiment, and it is made up of handwheel 1, nut 2, valve rod 4, support 3, valve gap 5, valve seat 6, flashboard 7, valve body 8.Its design feature be stainless steel sleeve 81 foundings in valve body 8, the chamber that together valve body 8 and valve gap 5 is surrounded with valve seat 6 is divided into upper, middle, and lower part; Top is that flashboard shields worn-out epicoele 21, and the middle part is media flow chamber 22, and the bottom is that flashboard shields worn-out cavity of resorption 23; Flashboard 7 places the center of the chamber that valve body 8 and valve gap 5 surrounded.
A is the static sealing section, and it comprises valve rod 4, valve gap 5, sealing ring 9, pressure cap 10; Its design feature is: place the epicoele of valve gap 5, pressure cap 10 to be screwed in the screw thread of upper end of valve gap 5 sealing ring 9, be pressed on the sealing ring 9, valve rod 4 passes the centre bore of pressure cap 10, valve gap 5, sealing ring 9 successively;
B is the cutting off seal section, it comprises valve rod 4, valve gap 5, and its design feature is: male conical sealing surface 41 is arranged at the bottom of valve rod 4, and there is concave cone shape sealing surface 51 at the middle part of valve gap 5, valve rod 4 penetrates the centre bore of valve gap 5, and male conical sealing surface 41 is coaxial with concave cone shape sealing surface 51;
C is the opening encapsulation section, and it comprises valve rod 4, valve gap 5, flashboard 7, and its design feature is: there is concave cone shape sealing surface 52 lower end of the middle part of valve gap 5, concave cone shape sealing surface 51, and there is male conical sealing surface 71 upper end of flashboard 7; The centre bore that valve rod 4 penetrates valve gap 5 links to each other with pin 11 with the upper end of flashboard 7, and concave cone shape sealing surface 52 is coaxial with male conical sealing surface 71.
The utility model is to realize (referring to accompanying drawing 1,2,3) like this; The handwheel 1 that turns clockwise, valve rod 4 promote flashboards 7 and move down, when male conical sealing surface 41 contacts with concave cone shape sealing surface 51, flashboard 7 stops to move down, flashboard 7 contacts and is adjacent to valve seat 6, and media flow chamber 22 is cut off, and this moment, static sealing section A and cutting off seal section B sealed; Be rotated counterclockwise handwheel 1, move on the valve rod 4 pulling flashboards 7, when male conical sealing surface 71 contacts with concave cone shape sealing surface 52, move on flashboard 7 stops, media flow chamber 22 is got through, and this moment, static sealing section A and opening encapsulation section C sealed.The effect of stainless steel sleeve 81 is to make the utility model high temperature resistant, corrosion-resistant and cost is low.
Therefore main feature of the present utility model is three seal sections and stainless steel sleeve 81 foundings to be arranged in valve body 8, and sealing is reliable, can the replace with pressure sealing ring and high temperature resistant, corrosion-resistant and cost is low, can broader applications in various thermal production well mouths.
