Abstract
The utility model relates to a butterfly valve suitably used under operating conditions with high temperature and high pressure, which comprises a valve body, a valve rod, a butterfly plate, and a valve seat. The top part of the valve rod has a guide slot which is matched with a guide block on the valve body. The utility model is characterized in that the upper part of the butterfly plate has a square hole which is sheathed on the valve rod; the position on the valve rod, which corresponds to the square hole is inclined square-rod-shaped; the lower part of the butterfly plate has a taper hole which is sheathed on a tapered positioning shaft; the positioning shaft is connected with the valve seat in a universal joint mode; an inclined square rod and the taper of the positioning shaft cause the butterfly plate to acquire transverse pressure, and the butterfly plate is tightly attached to a seal line of the valve seat. Thus, the utility model has the advantage of high sealing effects and can be suitable for the operating conditions with the high temperature and the high pressure.
Description
The utility model is relevant with butterfly valve, especially a kind of butterfly valve that is applicable under the high temperature and high pressure condition.
Butterfly valve has the fast advantage of opening speed, also has the shortcoming of poor sealing performance simultaneously, generally is defined in the pipeline of low pressure operating mode.
The utility model is to the improvement of existing butterfly valve, improves its sealability, to reach the purpose of using under the operating mode of High Temperature High Pressure.
Improvement project of the present utility model is: a kind of High Temperature High Pressure butterfly valve, comprise valve body, valve rod, butterfly plate and valve seat, valve rod top has guide slot to match with guide pad on the valve body, butterfly valve is characterized in that butterfly plate top has square hole to be socketed on valve rod, the square bar shape that is inclination on the valve rod corresponding to the position of square hole, the butterfly plate bottom has a taper hole to be socketed on a taper positioning shaft, and this positioning shaft joins with universal joint mode and valve seat.
Be further described below in conjunction with embodiment of the present utility model and accompanying drawing thereof.
Accompanying drawing is an embodiment's of the present utility model structure sectional view.
As shown in drawings, a kind of High Temperature High Pressure butterfly valve, comprise valve body 6, valve rod 10, butterfly plate 11 and valve seat 1, valve rod 10 tops have guide slot 7 to match with guide pad 8 on the valve body 6, when valve rod 10 can be done upper and lower displacement during by handwheel (not shown) driven rotary, this has been structure common in the butterfly valve, no longer describes in detail herein; It is characterized in that butterfly plate 11 tops have square hole 4 to be socketed on valve rod 10, be the square bar shape of inclination on the valve rod 10 corresponding to the position 9 of square hole 4, butterfly plate 11 bottoms have a taper hole 3 to be socketed on a taper positioning shaft 12, and this positioning shaft 12 joins with universal joint mode and valve seat 1.
Above-mentioned butterfly valve working principle is: when valve rod 10 from top to bottom during displacement, butterfly plate 11 is tending towards closing, square hole 4 edges of the square bar position 9 compressing butterfly plates 11 that valve rod 10 tilts, butterfly plate 11 also moves horizontally and presses to the valve base sealing line along butterfly plate 11 center lines when descending, finally, the top of butterfly plate 11 is compressed by the square bar position 9 of valve rod 10, and the below is compressed by taper positioning shaft 12; When valve rod 10 from bottom to top during displacement, butterfly plate 11 moves with aforementioned inverse process, opens valve.
Positioning shaft 12 with the universal joint mode that valve seat 1 joins can be: positioning shaft 12 lower ends are spherical and place in the through hole 13 of valve seat 1, regulate bolt 2 for one and be screwed into the pommel that through hole 13 is supporting positioning shaft 12, regulate the height of positioning shaft 12 with regulating bolt 2, and then adjust the gap between butterfly plate 11 and the valve base sealing line.The circumference side of butterfly plate 11 is convex globoidal 5, can make butterfly plate 11 fit in the valve base sealing line better.
Characteristics of the present utility model are that valve rod is provided with the square bar of inclination and the tapering of locating shaft, makes butterfly plate Obtain horizontal pressure and fit tightly in the valve base sealing line, so sealing effectiveness improves, can be applicable to The operating mode of HTHP.
