The purpose of this utility model is to overcome the defective that exists in the prior art, and a kind of bidirectional screw push-pull valve for denitrification apparatus is provided, and simple in structure, operator require great effort less when carrying out the plate Push And Release.
For achieving the above object, the technical solution of the utility model has provided a kind of bidirectional screw push-pull valve for denitrification apparatus, comprise valve body, the left socle that is fixedly connected with the left side of described valve body, the right support that is fixedly connected with the right side of described valve body, be installed on the left screw mandrel that the only relatively described valve body of described left socle inside slides mutually, be installed on the right screw mandrel that the only relatively described valve body of described right support inside slides mutually, the left plate that is fixedly connected with an end of described left screw mandrel, the left hand wheel that is connected with the other end of described left screw mandrel, the right plate that is fixedly connected with an end of described right screw mandrel, the right hand wheel that is connected with the other end of described right screw mandrel, be fixedly installed skimming baffle along vertical on the described valve body, described left plate and described right plate lay respectively at the left and right sides of described skimming baffle.
As preferably, described skimming baffle is welded and fixed mutually with the middle part of described valve body.
As preferably, described left screw mandrel, described left hand wheel have respectively two, and two described left screw mandrels, described left hands wheels parallel setting; Described right screw mandrel, described right hand wheel have respectively two, and two described right screw mandrels, described right hand wheels parallel setting.
As preferably, described left plate, described right plate are provided with sealing gasket respectively and between the described valve body.
As preferably, described left hand wheel is installed on the other end of described left screw mandrel by anticlockwise sleeve and left rectangular tube; Described right hand wheel is installed on the other end of described right screw mandrel by right rotation sleeve and right rectangular tube.
As preferably, the bottom of described left plate, described right plate evenly is provided with respectively a plurality of reinforcement gussets.
Advantage of the present utility model and beneficial effect are: by fix a skimming baffle in the valve body intermediate vertical, each inserts left plate and right plate or extracts to the skimming baffle direction since both sides, can guarantee that a side opens when carrying out the ash discharge operation, opposite side still is in closed condition, and about an original plate is divided into two, reduce friction rapid operation.
Description of drawings
Fig. 1 is the utility model schematic diagram;
Fig. 2 is the A-A place phantom of Fig. 1;
Fig. 3 is the B place enlarged view of Fig. 2.
Among the figure: 1, valve body; 2, left socle; 3, right support; 4, left screw mandrel; 5, right screw mandrel; 6, left plate; 7, right plate; 8, left hand wheel; 9, right hand wheel; 10, skimming baffle; 11, strengthen gusset.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is further described.Following examples only are used for the technical solution of the utility model more clearly is described, and can not limit protection domain of the present utility model with this.
Such as Fig. 1, shown in Figure 2, a kind of bidirectional screw push-pull valve for denitrification apparatus, comprise valve body 1, the left socle 2 that is fixedly connected with the left side of described valve body 1, the right support 3 that is fixedly connected with the right side of described valve body 1, be installed on the left screw mandrel 4 that the only relatively described valve body 1 of described left socle 2 inside slides mutually, be installed on the right screw mandrel 5 that the only relatively described valve body 1 of described right support 3 inside slides mutually, the left plate 6 that is fixedly connected with an end of described left screw mandrel 4, the left hand wheel 8 that is connected with the other end of described left screw mandrel 4, the right plate 7 that is fixedly connected with an end of described right screw mandrel 5, the right hand wheel 9 that is connected with the other end of described right screw mandrel 5, be fixedly installed skimming baffle 10 along vertical on the described valve body 1, described left plate 6 and described right plate 7 lay respectively at the left and right sides of described skimming baffle 10.
Without diagram, described skimming baffle 10 is welded and fixed mutually with the middle part of described valve body 1.
As shown in Figure 1 and Figure 2, described left screw mandrel 4, described left hand wheel 8 have respectively two, and two described left screw mandrels 4, described left hand wheels 8 parallel setting; Described right screw mandrel 5, described right hand wheel 9 have respectively two, and two described right screw mandrels 5, described right hand wheels 9 parallel setting.Since push-pull valve be positioned at the static blocker of denitrification apparatus below, the push-pull valve sectional dimension is larger, frictional force between plate and the adjacent elements is also larger, therefore adopt two manual spirals to come synchronous operation in every side, guarantee freeing in and out of every side plate, during operation, need two common rotation hand wheels of staff to move in the same direction.
