Abstract
The invention relates to an ascending and descending type gas cut-off valve which comprises a valve body and a valve clack. The valve body is made of a three-way tube; an annular valve base which has a diameter smaller than the diameter of the valve body is arranged in the valve body corresponding to a gas inlet end; a seal ring with a n-shaped longitudinal section is sleeved on the annular base ring; a closing plate is installed on the top of the valve body and at least one cylinder is arranged on the closing plate; the piston rod of the cylinder penetrates the closing plate to be connected with the valve clack; the valve clack ascends or descends relatively to the annular valve base with the drive of the piston rod, thus opening or closing a gas flowing channel. The valve has simple structure, stable and reliable use and good sealing effect; the valve clack is made of metal plate and not be fretted for a long term use and has long service life; the connection flange of the cut-off valve is welded with angle iron, thus having light weight and low production cost.
Description
Technical field
The present invention relates to the waste gas treatment equipment field, specifically is elevation type gas stop valve.
Background technique
In waste gas treatment equipment, stop valve is a waste gas treatment equipment commonly used, and its function is the processing gas that is used for connecting or block in the pipeline.At present, often adopt dish formula stop valve in the waste gas recycling equipment, though dish formula stop valve flap is simple in structure, manufacturing and easy to maintenance, but long-time the use easily of butterfly valve worn and torn, and used of a specified duration and the phenomenon that is not closed completely can occur, and sealing is relatively poor, need often maintenance, change, cause acquisition cost, user cost to increase.In addition, existing stop valve, the surface of contact that valve seat cooperates with flap is set to usually than larger area plane, easy like this material or the impurity that produces in the waste gas treatment process is accumulated on this plane, cause the identical imprecision of surface of contact and flap, reduced sealing, and, the connecting flange of stop valve usually and valve body integrally casting and make by machining, its structure is thick and heavy, the cost of production height.
Summary of the invention
The objective of the invention is to problem and shortage, a kind of good sealing effect, good stability, elevation type gas stop valve that cost of production is low are provided at above-mentioned existence.
Technological scheme of the present invention is achieved in that
Elevation type gas stop valve, comprise valve body, flap, valve body is made by three-way pipe, corresponding air inlet pipe end is provided with diameter than valve diameter circlet shape valve seat in the valve body, is nested with the seal ring that the longitudinal section is a n shape on the ring-type valve seat, and shrouding is installed on the valve body top, at least device has a cylinder on shrouding, the piston rod of cylinder passes shrouding and is connected with flap, and flap relative ring-type valve seat under the drive of piston rod is done lifting action, opens or close the gas communication passage.
Further technological scheme of the present invention is:
For guaranteeing that flap cooperates with valve seat closely, improve the sealing that cooperates between the two, be provided with three cylinders side by side on shrouding, the cylinder in the middle of placing is along the setting of valve body central axis, the intermediate piston bar is fixedlyed connected with flap, and both sides cylinder piston rod and flap are movable conflicts.In the time will closing the circulation of flap barrier gas, make middle cylinder stretch out piston rod earlier by digital control, flap is pressed on the ring-type valve seat, then control the both sides cylinder and stretch out piston rod simultaneously, piston rod is pressed on the flap, increase sealing; Otherwise in the time will opening flap by gas communication, earlier the cylinder both sides piston rod of withdrawing simultaneously in control both sides makes piston rod leave flap, and the intermediate piston bar of withdrawing again makes flap leave the ring-type valve seat, allows gas communication.
Further technological scheme of the present invention is:
Cause cooperating imprecision for the material that prevents to produce in the waste gas treatment process or impurity accumulate on ring-type valve seat and the fitting surface that flap contacts, reduce sealing, suction tude is a pipe fitting that diameter is littler than valve diameter, one end of suction tude stretches into valve body and the external diameter connecting ring about equally by an internal diameter and suction tude is integral suction tude and valve body soldering and sealing, and the ring-type valve seat is the prolongation that suction tude stretches into valve body.
For alleviating the weight of valve body, reduce production costs, the joining end of valve body adopts the boom angle solid welding to form connecting flange on its outer wall.
For strengthening the sealing that cooperates with valve seat, flap is a metal plate dish.
The present invention is provided with diameter than valve diameter circlet shape valve seat owing to having adopted in valve body, and on the ring-type valve seat, be nested with the seal ring that the longitudinal section is a n shape, adopt the annexation and the method for operation of the piston rod and the flap of a plurality of cylinders simultaneously, assurance the present invention is simple in structure, use reliable and stable, good sealing effect; Flap adopts sheet metal to make, and long-time the use can not worn and not torn, and long service life need not keeped in repair low cost of manufacture; Because the connecting flange of stop valve is welded by angle bar, can alleviate the weight of stop valve greatly again, reduce production costs.
The present invention is further illustrated below in conjunction with accompanying drawing.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is Fig. 1 partial enlarged drawing;
Fig. 3 is a decomposition texture schematic representation of the present invention.
Embodiment
As shown in the figure, elevation type gas stop valve of the present invention comprises valve body 1, flap 2, wherein:
Ring-type valve seat 13 stretches into one section pipe ring that valve body 1 prolongs for suction tude 11 the inners, and ring-type valve seat 13 can also be made also solid welding in valve body 1 by an angle bar that curves ring-type;
Being nested with the longitudinal section on the ring-type valve seat 13 is the seal ring 3 of n shape;
Shrouding 4 is installed on valve body 1 top, device has three cylinders 51,52,53 on shrouding 4, shrouding 4 is provided with the through hole that equates with number of cylinders, cylinder piston rod 71,72,73 passes through hole and is connected with flap 2, and wherein, the cylinder 52 in the middle of being arranged on is along valve body 1 central axis setting, the piston rod 72 of cylinder 52 is fixedlyed connected with flap 2, the piston rod 71,73 of both sides cylinder 51,53 and flap 2 movable conflicts certainly, also can be provided with other cylinders on the shrouding 4;
The joining end of valve body 1 adopts boom angle 8 solid weldings to form connecting flange on its outer wall.
Working principle of the present invention is:
When needs are opened flap 2 so that during gas communication, control both sides cylinder 51, the 53 both sides piston rod 71,73 of withdrawing simultaneously makes piston rod 71,73 leave flap 2, and the intermediate piston bar 72 of withdrawing again makes flap 2 leave ring-type valve seat 13, allows gas communication.
