Abstract
The utility model discloses a gate valve used for adjusting flow, which comprises a valve body, an inlet side valve seat, an outlet side valve seat, a gate plate, a valve rod, a valve cover and a hand wheel, wherein the gate plate is arranged in the valve body, the inlet side valve seat is arranged between the gate plate and the inlet end of the valve body, the outlet side valve seat is arranged between the gate plate and the outlet end of the valve body, the valve cover is fixedly arranged on the upper end of the valve body, one end of the valve rod passes through the valve cover and is fixed with the gate plate in the valve body, the hand wheel is arranged on the other end of valve rod; and on the section of the gate plate, a sealing surface between the gate plate and the inlet side valve seat is a wedge-shaped sealing surface which is narrow at bottom and wide at top, and the sealing surface between the gate plate and the outlet side valve seat is a vertical plane sealing surface. By adopting the structure, the gate valve has the same function as a common gate valve when the valve plate is closed, namely, the tighter the gate plate is closed, the better the sealing performance of the valve is, and also has the characteristic that when the gate plate carries out flow adjusting at a position of partial opening, the gate plate is at a stable state, so that the gate plate can not shake or vibrate.
Description
Technical field
The utility model relates to a kind of gate valve, is specifically related to a kind of gate valve that can be used for Flow-rate adjustment.
Background technique
Gate valve is a kind of valve products commonly used, mainly comprises valve body, suction side valve seat, outlet side valve seat, flashboard, valve rod, valve gap, handwheel, generally is used for the break-make of pipe-line system.The most frequently used gate valve be Wedge gate valve as shown in Figure 1, the cross section that is flashboard is the narrow down wide wedge shape that, flashboard is located in the valve body, be equiped with the suction side valve seat between flashboard and the valve body entrance point, be equiped with the outlet side valve seat between flashboard and the valve outlet end, valve gap is installed in the valve body upper end, the flashboard that valve rod one end passes in valve gap and the valve body is fixed, be arranged with handwheel on the valve rod the other end, the handwheel that matches with valve rod by operation can make valve rod do the oscilaltion campaign, and valve rod can drive coupled flashboard and move up and down.When wanting closing gate valve, flashboard moves downward until flashboard sealing surface and sealing surface of seat and fits tightly, thereby reaches the purpose of closing gate valve.Since flashboard, suction side valve seat and outlet side valve seat be down narrow wide wedge shape, therefore, flashboard moves down more, valve closing tight more.When flashboard moves up, flashboard breaks away from gradually with suction side valve seat and outlet side valve seat, the distance that flashboard moves up is big more, gap between flashboard and suction side valve seat and the outlet side valve seat is big more, when gate valve will be used for Flow-rate adjustment, need flashboard that different apertures is arranged, but because Wedge gate valve when opening, all have the gap between flashboard and suction side valve seat and the outlet side valve seat, and this gap is to increase along with the increase of flashboard aperture.Therefore, when valve was in the position of part unlatching, flashboard was in an unsure state, and along with flowing of medium, flashboard can produce and rock, even produced vibration.When gate valve is used to regulate flow, because flashboard is in the part opening state, therefore, the aisle spare minimum at flashboard position, rate of flow of fluid herein is the highest, and fluid is mobile least stable, and flashboard is owing to exist the gap with suction side valve seat and outlet side valve seat, this moment, flashboard played pendulum, finally cause rocking or vibrating of flashboard, use the damage that is easy to cause the gate valve component for a long time, serious meeting causes the vibration of whole pipe-line system, and therefore common Wedge gate valve generally can not be used for the adjusting of flow.
Summary of the invention
At the deficiencies in the prior art, the utility model provides that a kind of flashboard is in steady state when flashboard is in the part enable possition and carries out Flow-rate adjustment, and flashboard can not produce the gate valve that can be used for Flow-rate adjustment that rocks or vibrate.
For achieving the above object, the utility model provides a kind of gate valve that can be used for Flow-rate adjustment, comprise valve body, the suction side valve seat, the outlet side valve seat, flashboard, valve rod, valve gap, handwheel, flashboard is located in the valve body, be equiped with the suction side valve seat between flashboard and the valve body entrance point, be equiped with the outlet side valve seat between flashboard and the valve outlet end, valve gap is installed in the valve body upper end, the flashboard that valve rod one end passes in valve gap and the valve body is fixed, be arranged with handwheel on the valve rod the other end, on the described flashboard cross section, flashboard and suction side valve seat sealing surface each other are the narrow down wide wedge-type seal face of, and flashboard and outlet side valve seat sealing surface each other are the vertical plane sealing surface.
The beneficial effects of the utility model are: adopt said structure, because on the described flashboard cross section, flashboard and suction side valve seat sealing surface each other are the narrow down wide wedge-type seal face of, flashboard and outlet side valve seat sealing surface each other are the vertical plane sealing surface, therefore this gate valve had both had advantage identical with common gate valve when flashboard cuts out, be flashboard close tight more, the sealing of valve is good more, also have when flashboard is in the part enable possition and carries out Flow-rate adjustment, flashboard is in steady state, and flashboard can not produce the characteristics of rocking or vibrating.

Embodiment
Provided a kind of gate valve that can be used for Flow-rate adjustment as shown in Figure 2, comprise valve body 1, suction side valve seat 2, outlet side valve seat 3, flashboard 4, valve rod 5, valve gap 6, handwheel 7, flashboard 4 is located in the valve body 1, be equiped with suction side valve seat 2 between flashboard 4 and valve body 1 entrance point 11, be equiped with outlet side valve seat 3 between flashboard 4 and valve body 1 outlet end 12, valve gap 6 is installed in valve body 1 upper end, it is fixing with the flashboard 4 in the valve body 1 that valve rod 5 one ends pass valve gap 6, be arranged with handwheel 7 on valve rod 5 the other ends, on described flashboard 4 cross sections, flashboard 4 is the narrow down wide wedge-type seal face of with suction side valve seat 2 sealing surface 41 and 21 each other, and flashboard 4 is the vertical plane sealing surface with outlet side valve seat 3 sealing surface 42 and 31 each other.
Adopt said structure, because on described flashboard 4 cross sections, flashboard 4 is the narrow down wide wedge-type seal face of with suction side valve seat 2 sealing surface 41 and 21 each other, flashboard 4 is the vertical plane sealing surface with outlet side valve seat 3 sealing surface 42 and 31 each other, therefore this gate valve had both had advantage identical with common gate valve when flashboard 4 cuts out, be flashboard 4 close tight more, the sealing of valve is good more, also have when flashboard 4 is in the part enable possition and carries out Flow-rate adjustment, flashboard 4 is in steady state, and flashboard 4 can not produce the characteristics of rocking or vibrating.
