Description
Technical field
The present invention relates to valve technology field, especially relate to a kind of high temperature resistant butterfly valve.
Background technique
Butterfly valve is as a most important class valve, and application area is extremely wide at present.Such as, butterfly valve is applied in the environment of high temperature comparatively.For this reason, many butterfly valves are by adopting resistant to elevated temperatures material preparation.But in order to reach good sealing effect, the outer rim of flap and the inner chamber of valve seat of many butterfly valves are equipped with rubber seal.Like this, in the environment of high temperature comparatively, the time that rubber seal can be used is not long, thereby has reduced the working life of this butterfly valve.
Summary of the invention
The object of this invention is to provide a kind of high temperature resistant butterfly valve, it is not fragile that it has its rubber seal used, thus the feature of growing working life.
The technical solution adopted in the present invention is: high temperature resistant butterfly valve, comprise valve body, valve seat, flap and and this flap valve rod that be fixed together and that be vertical shape, simultaneously, the outer rim of this flap and the inner chamber of this valve seat are equipped with rubber seal, described flap inside is provided with the interior pipeline of annular along the circumference of this flap, simultaneously, the inside of this valve rod is provided with straight tube road along the shaft axis of this valve rod, and this straight tube road and this interior pipeline connect, and, the cover that the top of this valve rod is positioned at the outside seal cooperation of this valve body has into water cover, this water inlet cover is connected to the first water source, and the position that the top of this valve rod is positioned at the inside of this water inlet cover is provided with the water inlet for connecting this water inlet cover and this straight tube road, the lower end of this valve rod is sealedly connected with out water jacket, this water outlet is arranged with water outlet, and after this straight tube road direction downward-extension, stretching into this goes out in water jacket.
Described valve seat inside is provided with outer pipeline around the circumference of this valve base cavity, and this outer pipeline is communicated with second water source and osculum.
Described the first water source and this second water source independently arrange separately.
The advantage that the present invention has is: rubber seal is not fragile, thereby working life is longer.In the flap of high temperature resistant butterfly valve of the present invention and valve seat all by there being circulating water, thereby the moment rubber seal is cooled, and then make this rubber seal not fragile, greatly improved its aging speed, extended the working life of this butterfly valve.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described:
Fig. 1 is that the master of embodiments of the invention looks sectional view.
In figure: 10, valve body; 20, valve seat, 21, outer pipeline, 22, osculum, 23, second water source; 30, flap, 31, interior pipeline; 40, valve rod, 41, straight tube road, 42, water inlet; 51, water inlet cover, 511, the first water source, 52, go out water jacket, 521, water outlet; 60, rubber seal.
Embodiment
Embodiment, as shown in Figure 1: high temperature resistant butterfly valve, comprise valve body 10, valve seat 20, flap 30 and and this flap 30 that be fixed together and be the valve rod 40 of vertical shape.Meanwhile, the inner chamber of the outer rim of this flap 30 and this valve seat 20 is equipped with the rubber seal 60 cooperatively interacting.Further say, these flap 30 inside are provided with the interior pipeline 31 of annular along the circumference of this flap 30, and the inside of this valve rod 40 is provided with straight tube road 41 along the shaft axis of this valve rod 40, and this straight tube road 41 connects with this interior pipeline 31.And, the cover that the top of this valve rod 40 is positioned at the outside seal cooperation of this valve body 10 has into water cover 51, this water inlet cover 51 is connected to the first water source 511, and the position that the top of this valve rod 40 is positioned at the inside of this water inlet cover 51 is provided with the water inlet 42 for connecting this water inlet cover 51 and this straight tube road 41, the lower end of this valve rod 40 is sealedly connected with out water jacket 52, this goes out water jacket 52 and is provided with water outlet 521, and this straight tube road 41 goes out in water jacket 52 to stretching into this after downward-extension.Obviously, what the lower end of this valve rod 40 was sealed and matched be inserted in this goes out in water jacket 52, thereby this goes out water jacket 52 and can not affect the normal rotation of this valve rod 40.Like this, the water at this first water source 511 enters the top on this straight tube road 41 by this water inlet cover 51, water inlet 42, enter afterwards this interior pipeline 31 and carry out coolingly finally entering this and going out water jacket 52 and flow out from water outlet 521 afterwards to being arranged at rubber seal 60 on this flap 30.
Further say, these valve seat 20 inside are provided with outer pipeline 21 around the circumference of these valve seat 20 inner chambers, and this outer pipeline 21 is communicated with second water source 23 and osculum 22.This second water source 23 and this first water source 511 be independent setting so that control respectively separately.Like this, the water of this second water source 23 enters that this outer pipeline 21 is rear to carry out coolingly to being arranged at rubber seal 60 in the inner chamber of this valve seat 20, then flows out through this osculum 22.
In sum, in the flap of high temperature resistant butterfly valve of the present invention and valve seat all by there being circulating water, thereby the moment rubber seal is cooled, make this rubber seal not fragile, extended the working life of this butterfly valve.
The foregoing is only the preferred embodiments of the present invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes specification of the present invention and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
