Abstract
The utility model relates to an improved gate valve, which consists of a valve body, a valve seat, a valve plate, a valve plate sliding channel and a valve rod. The valve seat in the valve body is divided into two sections, and is connected with an expansion joint. A hug is fixed on the outer margin of a section of the valve seat close to one side of the valve, a post rod is fixed on the hug, and the other end of the post rod passes through a filling box and extends out of one side of the valve body. For the post rod is used to control the displacement of the valve seat to realize no space between the valve seat and the valve rod, and ensure that high temperature media can not enter a valve chamber, thereby removing the difficulty that the current gate valve can not prevent high temperature media from entering into the valve body to cause residue and coking, and ensure that the valve opens and closes smoothly.
Description
The utility model relates to a kind of improved gate valve, but especially a kind of clamping type gate valve that high temperature media is controlled in pipe conveying procedure that is applicable to.
At present, the gate valve that High Temperature and Heavy Oil is being controlled in pipe conveying procedure that oil refinery generally uses, because the lifting of valve plate when opening state, cause between valve plate and the valve seat gapped, cause the part High Temperature and Heavy Oil to enter valve pocket retention, coking, therefore, when valve need be closed, these cokings then make valve plate close fully and put in place, thereby leak in taking place; And when valve need be opened once more, these cokings then easily made valve plate be difficult to promote again, took place stuck.
But the purpose of this utility model is to provide a kind of improved clamping type gate valve, and it can make valve plate and valve seat fit tightly no gap, thereby can avoid high temperature media to enter valve pocket and produce coking, guarantees stuck or interior leakage not to take place the valve opening and closing freedom.
But clamping type gate valve of the present utility model, comprise valve body, valve seat, valve plate, valve plate chute and valve rod, it is characterized in that: the valve seat in the described valve body is divided into two-section and is connected by expansion joint, be fixed with lug on the outer rim of one section valve seat of close valve one side, be fixed with push rod on the lug, the other end of push rod passes Stuffing box and stretches out a side at valve body.
Described valve plate is flat, on one side it is a through hole, Yi Bian be blind plate.
Below in conjunction with drawings and Examples the utility model is illustrated.
Fig. 1 is the utility model structural representation.
As shown in Figure 1, the valve seat in the valve body 1 is made of left and right two-section valve seat 8-2,8-1, and the expansion joint 9 by monophasic waveform between the two-section valve seat connects.Be fixed with lug 5 on the outer rim near the left valve seat 8-2 of valve one side, be fixed with push rod 7 on the lug, the other end of push rod passes Stuffing box 6 and stretches out opposite side at valve body 1, and this side of Stuffing box and valve body is connected and fixed.
Valve plate 2 is flat, and the top is a blind plate, and bottom is a through hole.The upper end of valve plate and valve rod 4 are connected and fixed, and the turn valve rod can drive valve plate and move up and down in valve plate chute 3.Move lifting on valve plate, when making following through hole and valve coordination, valve is opened fully; When valve plate moves down, when making the blind plate of top and valve coordination, valve is closed fully.During mobile valve plate 2, at first should loosen valve seat 8-2 by mobile push rod 7, make this valve seat leave valve plate 2, valve plate can be opened state from gold and transfer full-shut position to, or transfer full-gear to from full-shut position, when valve plate promotes or moves down when putting in place, another mistake makes valve seat 8-2 compress valve plate 2 to rotating push rod, make between valve seat and the valve plate and do not have the gap, like this, High Temperature and Heavy Oil just can't enter valve pocket, thereby can avoid High Temperature and Heavy Oil to retain in valve pocket effectively, coking, this shows, valve plate promotes or moves down the sealing when putting in place, is that promotion by push rod 7 makes left valve seat 8-2 compress valve plate 2 to realize, and the displacement of left valve seat 8-2 to be expansion joint 9 by monophasic waveform offset.Because stressed during valve seat 8-2 displacement is the internal force of valve body 1, therefore whole piping had no effect.
The utility model is because the valve seat displacement of adopting push rod to come control valve body, make and fit tightly no gap between valve seat and the valve plate, so make high temperature media can't enter valve pocket, solved effectively existing valve plate can't avoid high temperature media to stay into valve pocket and retain, the technical barrier of coking, make valve opening and closing easily, freely, stuck or interior leakage phenomenon can not take place.
