Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
Embodiment 1:
A kind of low-temperature safety valve preventing flap from rotating as Figure 1-4, comprises, valve body 1, valve gap 2, valve rod 3, valve seat 4, flap 5 and pressure ring 6.
It is inner that flap 5, valve rod 3 are located at valve body 1, and flap 5 is fixed on one end of valve rod 3, and flap 5 is located at above valve seat 4, and pressure ring 6 is fixed between valve body 1 and valve gap 2.
Flap 5 comprises flap dish 52, and flap dish 52 upper center is provided with projection 53, and projection 53 upper center is provided with the flap handle 54 be connected with valve rod 3; Flap dish 52, projection 53 and flap handle 54 are one-body molded, have identical central shaft, and are provided with blind hole at central axis direction.The cross section of projection 53 is capsule shape.
Sealing 51 is provided with, Sealing 51 inserted valve seat 4 bottom flap 5.The material of Sealing 51 is teflon.
The center of pressure ring 6 is provided with perforate, and the diameter of perforate and the diameter of flap handle 54 match, and pressure ring 6 is sheathed on the flap handle 54 of flap 5 by perforate.Namely flap handle 54 is placed in perforate.
The lower surface center of pressure ring 6 is provided with groove 61.
Be provided with protruding opposite side 62 along groove 61 both sides, projection 53 embeds protruding opposite side 62 and fixes flap 5, and the height h1 of protruding opposite side 62 is more than or equal to the height h2 of projection 53.By devising protruding opposite side on pressure ring, when it is set on flap, the projection on flap embeds this protruding opposite side, thus limits the rotation of flap.The cross section of protruding opposite side 62 is that minor arc is arc, and after protruding opposite side 62 suits with projection 53, the cross section of formation is circular.The design of this protruding opposite side fit, makes more compact structure, and after projection embeds groove, flap can only move up and down vertically at axial direction, prevents it from rotating further.
The upper surface center of pressure ring 6 is provided with taper projection 63, and flap handle 54 is sheathed in taper projection 63.
The upper surface of pressure ring 6 is provided with a pair pressure compensation opening 64, and pressure compensation opening 64 lays respectively at taper projection 63 both sides.When flap is opened, pressure compensation opening balances the pressure in valve gap cavity and valve body cavity, avoids Reseating pressure of a safety valve to produce deviation.
Of the present utility modelly serve prevent flap from rotating by adding pressure ring on flap, solve because flap rotates the problem causing Sealing to damage.
Below the preferred embodiment that the utility model is created is illustrated, but the utility model is created and is not limited to described embodiment, those of ordinary skill in the art can also make all equivalent modification or replacement under the prerequisite without prejudice to the utility model creative spirit, and these equivalent modifications or replacement are all included in the application's claim limited range.
