Embodiment
Below in conjunction with accompanying drawing and specific embodiment, describe the utility model in detail, illustrative examples wherein and explanation are only used for explaining the utility model, but not as to restriction of the present utility model.
As shown in Figure 1 and Figure 2, the gate valve that is applicable to high temperature, high pressure, high sand content, high-corrosion medium described in this embodiment, it comprises flap type body, and described flap type body is by valve body 1, valve plate 2, valve rod 10, valve gap 11, valve seat combination installation composition; Described valve seat combination device, is comprised of valve seat 5, valve body lining 9, C shape metal o-ring 3, seal ring A7, seal ring B8, elastic support circle A4, elastic support circle B6; Described valve seat 5 contacts with valve plate 2; Match with valve seat 5 in described valve body lining 9 one end, its other end contacts with valve body 1, between valve body lining 9 and valve seat 5, is provided with sealed step; Described C shape metal o-ring 3 is placed between valve seat 5 and valve body lining 9, and its opening is installed outwardly; Described seal ring A7, seal ring B8 are that the PEEK seal ring by stainless steel spring circle and high temperature high voltage resistant combines; Described elastic support circle A4 is installed between valve seat 5 and valve body lining 9; Elastic support circle B6 is installed in the matching hole of valve body lining 9 and valve body 1.
Working principle of the present utility model is as follows:
Valve seat combination device symmetry is installed on flashboard 2 both sides, so that this gate valve does not in use have directivity; Valve seat 5 contacts with valve plate 2, plays and close seal action during valve closing; Match with valve seat 5 in valve body lining 9 one end, the other end contacts with valve body 1, can prevent the direct side blow valve body of fluid, between valve body lining 9 and valve seat 5, is designed with sealed step, can prevent that mud or sand from entering valve pocket; C shape metal o-ring 3 is placed between valve seat 5 and valve body lining 9, opening outwardly, the gap between sealed valve body lining 9 and valve seat 5; Seal ring A7, seal ring B8 are that the PEEK seal ring by stainless steel spring circle and high temperature high voltage resistant combines, the gap between sealed valve body lining 9 and valve body 1; Elastic support circle A4, elastic support circle B6 can guarantee valve seat 5 and the close positioning of valve body lining 9 in matching hole.
The gate valve that is applicable to high temperature, high pressure, high sand content, high-corrosion medium described in the utility model, it has simple in structure, reasonable in design, handling safety, be more suitable in the extreme environment work at high temperature, high pressure, high sand content, high-corrosion medium, greatly improved valve in the all-environment Applicable scope of Oil Field.
The above is only better embodiment of the present utility model, and the equivalence of doing according to structure, feature and principle described in the utility model patent claim therefore all changes or modifies, and is included in the utility model patent claim.
