Embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples for illustration of the present invention, but are not used for limiting the scope of the invention.
As shown in Figure 1, a kind of juice steam valve of the embodiment of the present invention, it comprises handwheel 1, valve rod 7, valve seat 2, valve gap 3, flap 9, arrestment mechanism, valve body 4, air input joint 5 and air outlet adapter 6, described valve seat 2 is arranged on the top of valve gap 3, the lower end of described valve rod 7 is connected with the flap 9 being located at described valve body 4 inside with valve gap 3 through described valve seat 2 successively, the upper end of described valve rod 7 is threaded with handwheel 1, be provided with between described valve rod 7 and described valve seat 2 and limit described valve rod 7 and rotate and make valve rod 7 do the arrestment mechanism of oscilaltion campaign, described air input joint 5 and air outlet adapter 6 are located at the relative both sides of described valve body 4 respectively, described air input joint 5 and air outlet adapter 6 one of them contact with described flap 9 and be connected, the lower end of described handwheel 1 extends to the inside of described valve seat 2, and single-row tapered roller bearing 8 is provided with between handwheel 1 and valve seat 2, this single-row tapered roller bearing 8 can reduce the resistance between handwheel and valve seat, save manpower and time, increase work efficiency.
In order to ensure the sealing between valve gap 3 and valve body 4, the valve gap 3 of the present embodiment is connected by flange plate 13 with valve body 4.
The arrestment mechanism of the present embodiment comprises guiding groove 10 and braking back-up ring 11, described guiding groove 10 is vertically located on described valve seat 2, described braking back-up ring 11 is fixed on described valve rod 7, described braking back-up ring 11 is slidably connected with described guiding groove 10, handle with sleeve 1, if any there is no arrestment mechanism, so valve rod 7 can be followed handle 1 and rotated together, and can not upper and lower displacement be produced, owing to adding arrestment mechanism, when handle 1 rotates, braking back-up ring 11 can only move up and down along guiding groove 10, and then band ovable valve stem 7 does oscilaltion campaign.Preferably, guiding groove 10 is polygonal chute, and to brake back-up ring 11 be the polygonal back-up ring matched with this guiding groove 10.It is to be noted, the arrestment mechanism of the present embodiment can also be other structure, rotate and make valve rod do oscilaltion campaign be as the criterion to realize restriction valve rod, as can be, circular guiding groove, and the braking back-up ring of circular arc, when the both sides at guiding groove arrange limiting stopper, braking back-up ring, between these two limiting stoppers, makes braking back-up ring can only move along the above-below direction of guiding groove.
Because valve rod 7 be in whole juice steam valve motion amplitude maximum, hold flimsy position most; therefore; axle sleeve 12 is provided with between the valve rod 7 of the present embodiment and valve gap 3; the effect of this axle sleeve 12 reduces the resistance between valve rod 7 and valve gap 3; to protect valve rod not to be damaged, improve the working life of juice steam valve.
The conveniently keying of juice steam valve, one end of the air input joint of the present embodiment extends to the inside of valve body, the end that air input joint 5 is positioned at valve body 4 inside is bend pipe, flap 9 contacts with the opening end of this bend pipe and connects, make when juice steam valve is for opening, flap 9 compresses air input joint 5 under the effect of valve rod 7 and handle 1, air input joint 5 is not communicated with air outlet adapter 6, when needs are vented, handle with sleeve 1, valve rod 7 is moved upward, and under the effect of air-flow, make the resistance between handle 1 and valve rod 7 less, flap 9 leaves the port of air input joint fast, air input joint 5 is communicated with air outlet adapter 6.The bend pipe of air input joint 5 is preferably right-angle elbow pipe, and gas level enters juice steam valve, contacts connect after 90 degree of bendings with flap 9.The bend pipe of the present embodiment or can adopt sheet metal part make for punched bend, and because juice steam valve is operating on low voltage state, less demanding to intensity, therefore, in order to save material, can also adopt clout sheet metal part to make.
In addition, the opening end of the bend pipe of the present embodiment is arranged with guard ring, and this guard ring adopts stainless steel material to make, and the lower surface of flap is arranged with rubber plate, and this rubber plate contacts with the guard ring of bend pipe opening end the effect playing sealing.
A kind of juice steam valve that the embodiment of the present invention provides, has the following advantages:
1, adopt the structure of handwheel, valve seat, valve rod, flap and arrestment mechanism, and single-row tapered roller bearing is set between handwheel and valve seat, the resistance between handwheel and valve seat can be reduced thus, save manpower and time, improve working efficiency;
2 and axle sleeve is set between valve rod and valve seat, decrease the resistance between valve rod and valve gap, valve rod can be protected not to be damaged, improve the working life of juice steam valve.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and replacement, these improve and replace and also should be considered as protection scope of the present invention.
