Abstract
The invention relates to a discharge valve of a VC mixer, which concretely is a main part on the VC mixer, performs the function of discharging, belongs to the technical field of mixing mechanical equipment and comprises a cylinder, a valve shell and a spherical valve body, wherein the valve shell, the spherical valve body and a fixed flange are fixed into a whole, two supporting arms are arranged on the spherical valve body, a copper sleeve is respectively sleeved on the two supporting arms, a supporting sleeve is sleeved on the copper sleeve, the supporting sleeve is fastened on the valve shell through a bolt, the two supporting arms on the spherical valve body are connected with the cylinder through the supporting sleeves, and the spherical valve body is driven by the cylinder to rotate. A tetrafluoroethylene sealing ring is arranged at the matched part of the spherical valve body with the fixed flange and the valve shell. The invention has simple, compact and reasonable structure; the spherical valve body can be controlled to turn at an angle of 90 degrees by opening and closing the cylinder; when the cylinder is opened, the spherical valve body can turn for 90 degrees, and a discharge opening is opened to be the largest for discharging; when the cylinder is closed, the spherical valve body is reset, is tightly matched with the tetrafluoroethylene sealing ring, has good sealing performance and is not easy to leak; and the tetrafluoroethylene sealing ring is convenient to replace and simple to maintain.
Description
Technical field
The present invention relates to a kind of VC mixing machine discharging valve, critical piece on the VC mixing machine specifically plays the function of blowing, belongs to the mixing machinery equipment technical field.
Background technique
Because existing mixing machine discharging valve is that spherical valve body is located on one side, comprise strut, open and close cylinder, seal ring is arranged on the spherical valve body outer, opens and closes cylinder and connects the 0-60 degree swing up and down of spherical valve plate do by strut, rotating shaft, trailing arm, plays the function of blowing.This discharging valve during unlatching, because cylinder drives swinging up and down of valve plate, makes valve plate to swing in the angle of 60 degree, and during discharging, discharge port is failed all unimpeded, and discharging is obstructed, and also has partly to expect to remain on the valve plate, fails to drain.When closing, because closing of valve plate transmit strength by cylinder and give rotating shaft, trailing arm, often after the action, trailing arm has looseningly will cause that valve plate is not closed completely, and causes and leaks the material phenomenon.And there is to come off operation inconvenience during the seal ring that glues on the valve plate.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, thereby provide a kind of discharging fast, close tightly, safeguard simple VC mixing machine discharging valve.
According to technological scheme provided by the invention, VC mixing machine discharging valve comprises cylinder, valve shell, spherical valve body, adopt screw, fastening flange that valve shell and spherical valve body are fixed into one, feature is: described spherical valve body is provided with and plays two trailing arms that rotate with supporting effect, copper sheathing is set on two trailing arms, suit supporting sleeve on the described copper sheathing, described supporting sleeve is fastened on the valve shell with screw, two trailing arms on the spherical valve body are connected with cylinder by supporting sleeve, and cylinder drives spherical valve body and rotates.
Described spherical valve body and fastening flange and valve shell cooperation place are provided with four fluorine ethylene seal rings.Described spherical valve body adopts stainless steel material to make.Described spherical valve body accounts for 1/4 of whole spherome surface, and all the other partly are empty.
Compared with the prior art the present invention has the following advantages:
The present invention is simple, compact and reasonable for structure; Open and close cylinder, can control spherical valve body and be the upset of an angle of 90 degrees degree; When opening cylinder, spherical valve body can turn over 90 degree, discharge port is driven to maximum discharge; During shifter cylinder, spherical valve body resets, and closely cooperates with four fluorine ethylene seal rings, and good seal performance is not leaked material; And four fluorine ethylene seal rings are changed convenient, safeguard simple.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Embodiment during following the present invention incites somebody to action in conjunction with the accompanying drawings is further described:
As shown in Figure 1: comprise cylinder 1, supporting sleeve 2, spherical valve body 3, valve shell 4, fastening flange 5, four fluorine ethylene seal rings 6, copper sheathing 7 etc.
The present invention adopts screw, fastening flange 5 that valve shell 4 and spherical valve body 3 are fixed into one.Described spherical valve body 3 is provided with four fluorine ethylene seal rings 6 with fastening flange 5 and valve shell 4 cooperation places.Described spherical valve body 3 adopts stainless steel material to make.Described spherical valve body 3 is provided with and plays two trailing arms that rotate with supporting effect, two copper sheathings 7 are set on two trailing arms, suit supporting sleeve 2 on the described copper sheathing 7, described supporting sleeve 2 usefulness screws are fastened on the valve shell 4, two trailing arms on the spherical valve body 3 are connected with cylinder 1 by supporting sleeve 2, and cylinder 1 drives spherical valve body 3 and rotates.
When valve closing, spherical valve body and mixing machine blade keep certain interval, discharge port buildup at the bottom of the bucket when avoiding the mixing machine operation.When Open valve, spherical valve body can be controlled by cylinder, turns over 90 degree, and because of spherical valve body has only 1/4 of whole spherome surface, all the other partly are empty.After the upset, discharge port is unblocked, and discharging is fast and clean, can not touch the mixing machine element during rotation.In the discharge port position, fastening flange 5, valve shell 4 adopt four fluorine ethylene seal rings with spherical valve body 3 places of matching, because of spherical valve body is a stainless steel, and four fluorine ethylenes have elasticity and excellent self lubricity, cooperate with spherical valve body, good seal performance, and when upset is free and relaxed, and spherome surface is not easy to wear.Not having powder in the open and close process is bonded on the discharge port.Because spherical valve body has two fixing trailing arms, trailing arm directly is connected with cylinder by supporting sleeve, and the cylinder action directly drives spherical valve body and makes 90 degree flip-flop movements, and is convenient and swift.And spherical valve body and discharge port sealing part adopt four fluorine ethylene seal rings, and soft or hard cooperates, and guarantee the discharging sealing, if need to change four fluorine ethylene seal rings, only need unclamp fastening flange after the long-time running, and the rare seal ring of promptly replaceable tetrafluoro second is simple to operation.
