Abstract
The invention discloses a bidirectional sealing butterfly valve with a movable valve seat. The bidirectional sealing butterfly valve comprises a valve body and a valve seat, and further comprises at least one elastic rubber ring and an elastic pressure plate, wherein the valve seat is in transition fit with the valve body; the elastic rubber ring is arranged on one side of the valve seat; the elastic pressure plate is arranged on the other side of the elastic rubber ring, and fixed with the valve body through a nut. According to the invention, a fixed valve seat structure is changed to be a movable valve seat structure, so as to ensure that the sealing effect is very good no matter water flows in from which port of the butterfly valve.
Description
Technical field
The invention belongs to valve technology field, relate in particular to a kind of two way sealed formula butterfly valve that has movable valve seat.
Background technique
Valve is the controlling component in the fluid delivery system, have by, adjusting, water conservancy diversion, prevent functions such as adverse current, voltage stabilizing, shunting or overflow pressure release.The valve that is used for liquid control system, from the simplest stop valve to very complicated robot control system(RCS) used various valves, its kind and specification are quite various.Valve can be used for controlling flowing of all kinds fluids such as air, water, steam, various Korrosionsmedium, mud, oil product, liquid metal and radiating medium.Valve also is divided into cast iron valve, cast steel valve, stainless valve etc. according to material.
Butterfly valve is Flap valve again, is a kind of modulating valve simple in structure, also can be used for the switch control of low pressure pipeline medium simultaneously.Butterfly valve refers to that closure member (flap or butterfly plate) is disk, centers on a kind of valve that valve shaft rotates to reach open and close, and main rising cut off and throttling action on pipeline.The butterfly valve open-shut device is a discoidal butterfly plate, and the axis around himself in valve body rotates, thereby reaches the purpose that opens and closes or regulate.
Butterfly valve comprises valve rod, valve body, valve plate, valve seat, and in the prior art, valve seat is to be fixed on the valve body, and valve plate and valve seat constitute sealing configuration, and when in use, valve seat is fixed, if from intaking away from the valve seat end, the valve plate sealing is fine; But, if from nearly valve seat end water inlet, then the phenomenon that valve plate leaks can take place.
Summary of the invention
The purpose of this invention is to provide a kind of two way sealed formula butterfly valve that has movable valve seat, to solve the problems referred to above that prior art exists.
In order to finish the object of the invention, the invention provides a kind of two way sealed formula butterfly valve that has movable valve seat, comprise valve body, valve seat, also comprise flexible rubber ring, spring bearer plate, described valve seat and described valve body are transition fit, described valve seat one side is provided with at least one described flexible rubber ring, and described spring bearer plate is located at the opposite side of described flexible rubber ring and is fixed by nut and described valve body.
The fixed valve seat construction of the present invention is set to movable valve seat construction, guaranteed that current no matter from that mouthful water inlet of butterfly valve, can reach extraordinary sealing effect.
Description of drawings
Fig. 1 is structural representation of the present invention;
Embodiment
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail.
As shown in Figure 1, in order to finish the object of the invention, the invention provides a kind of two way sealed formula butterfly valve that has movable valve seat, comprise valve body, valve seat, also comprise flexible rubber ring, spring bearer plate, described valve seat and described valve body are transition fit, and described valve seat one side is provided with at least one described flexible rubber ring, and described spring bearer plate is located at the opposite side of described flexible rubber ring and is fixed by nut and described valve body.
Need to prove that above-mentioned valve body and valve seat are for closely cooperating, the gap between described valve body and the described valve seat is very little, guarantees that valve seat is movable, has to guarantee valve seat radially activity by a relatively large margin.Above-mentioned spring bearer plate is used for fixed valve base, be provided with flexible rubber ring between pressing plate and the valve seat, flexible rubber ring is according to the impact force size of water to valve seat, thereby adjust the tension force of flexible rubber ring automatically, and then guaranteed the sealing of butterfly valve, make butterfly valve no matter from that end water inlet, butterfly valve can keep good sealing.
Above-mentioned only is embodiment of the present invention, for those of ordinary skill, under the prerequisite that does not break away from the principle of the invention, can also make some improvements and modifications, and these improvements and modifications also should be considered as protection scope of the present invention.
Claims (1)
