Abstract
The utility model provides an extension upward type pneumatic dumping valve with a cylinder arranged aside. A valve seat of the utility model is arranged on the upper part of the valve body; a valve spool is mounted in the valve body. The bottom of the valve body is fixed on the top face of the right part of a fixing plate by bolts and nuts. The valve spool has filler and is positioned in the inner cavity at the lower part of the valve body, compressed by a press cap and nuts. A flange is mounted at the lower part of valve spool, through a joint and is fixedly connected to the right end of a lever via a pin shaft. A supporting column is fixed on the lower side at the middle part of the fixing plate via screws and nuts, and is also fixedly connected to the middle part of the lever via a pin shaft. The fixing plate is mounted with screw rods and nuts. The cylinder is provided with an air inlet hole and an exhaust hole. The piston (not graphed) of the cylinder through the joint is connected with the left end of a cross rod via a pin shaft. As the cylinder is arranged aside the dumping valve, when the valves leaks, the medium does not fall into the cylinder and damage the cylinder. The valve is made of the enamel glass body, and the valve seat is made of the polytetrafluoroethylene, both having good anti-corrosive performance; the adoption of the filler has good sealing effect.
Description
Technical field
The utility model relates to a kind of side and puts the pneumatic baiting valve of cylinder extension upward type, and it is the dispensing valve that is used on the retort, belongs to the technical field of petrochemical equipment.
Background technology
Pneumatic baiting valve is a dispensing valve indispensable on the retort, it also can be used by remote control by compressed air-driven, safe and convenient, cylinder always is contained in the below of baiting valve, if dielectric leakage in case take place in the stuffing box of sealed valve core, will enter cylinder and damage to cause cylinder, baiting valve is difficult to normal operation when stopping the supple of gas or steam fault in addition, lacks corresponding hand-operating device and easily causes the accident of stopping the supple of gas or steam.
Summary of the invention
The purpose of this utility model is to provide a kind of side to put the pneumatic baiting valve of cylinder extension upward type, it is contained in cylinder on the next door of valve, promote to promote spool again behind the lever by piston rod, can overcome the shortcoming that cylinder damages like this, its valve body spool all adopts the enamel body, valve seat is made of polytetrafluoroethylene (PTFE), has extremely strong corrosion resistance.
The structure that the pneumatic baiting valve of cylinder extension upward type is put on the side is that valve seat (11) places valve body (12) top, spool (13) is contained in the valve body (12), the bottom of valve body (12) is fixed on above the right part of fixed head (15) with bolt (16) and nut (17), filler (14) is housed on the spool (13) and is arranged in the inner chamber of valve body (12) bottom, and compress with gland (18) and nut; Connecing dish (6) is contained on the bottom of spool (13), also be fixed in the right-hand member of lever (9) with bearing pin (10) by joint (7,8), pillar (2) with screw and nut (20) be fixed on fixed head (5) middle part below, also use bearing pin (21) to be fixed in the middle part of lever (9), screw rod (3) and nut (4,22) are housed on the fixed head (5); Cylinder (23) has air admission hole (24) and steam vent (25), and its piston (not shown) is connected with cross bar (9) left end with bearing pin (24) by joint (1).Filler (14) is made up of the stuffing box (27) of two V-rings and (28) and O shape ring (29), and make with polytetrafluoroethylene (PTFE) stuffing box (27) and (28), and it is to make with rubber cylinder-packing fluoroplastics that O shape is encircled (29).
The advantage that the pneumatic baiting valve of cylinder extension upward type is put on the side is the side that cylinder places baiting valve, can not fall in the cylinder when filler takes place to leak, so can not damage cylinder, the valve body spool all is enamel bodies in addition, valve seat is made of polytetrafluoroethylene (PTFE), has extremely strong corrosion resistance.The life-span of baiting valve is prolonged, also safer in the use.
Description of drawings:
Fig. 1. the pneumatic baiting valve schematic diagram of cylinder extension upward type is put on the side
Fig. 2. the filler combination schematic diagram
By Fig. 1, valve seat (11) places valve body (12) top, spool (13) is contained in the valve body (12), the bottom of valve body (12) is fixed on above the right part of fixed head (15) with bolt (16) and nut (17), filler (14) is housed on the spool (13) and is arranged in the inner chamber of valve body (12) bottom, and compress with gland (18) and nut; Connecing dish (6) is contained on the bottom of spool (13), also be fixed in the right-hand member of lever (9) with bearing pin (10) by joint (7,8), pillar (2) with screw and nut (20) be fixed on fixed head (5) middle part below, also use bearing pin (21) to be fixed in the middle part of lever (9), screw rod (3) and nut (4,22) are housed on the fixed head (5); Cylinder (23) has air admission hole (24) and steam vent (25), and its piston (not shown) is connected with cross bar (9) left end with bearing pin (24) by joint (1).
By Fig. 2, filler (14) is made up of the stuffing box (27) of two V-rings and (28) and O shape ring (29), and make with polytetrafluoroethylene (PTFE) stuffing box (27) and (28), and it is to make with rubber cylinder-packing fluoroplastics that O shape is encircled (29).
The specific embodiment
Compressed air enters cylinder (23) back from air admission hole (24) and promotes the piston motion in Fig. 1, be connected with lever (9) by joint (1), making lever (9) drive spool (13) moves in valve body (12), when compressed air stops to enter cylinder (23), available manpower rotating screw bolt (3) drives valve event, therefore stopping the supple of gas or steam when breaking down, baiting valve utilizes manpower still can operate.The filler of stuffing box does not adopt the square packing of joining commonly used, but the O shape ring of using the V-ring of polytetrafluoroethylene (PTFE) and rubber cylinder-packing fluoroplastics instead combines, it has improved corrosion resistance, also anti-organic molten material, and its sealing effectiveness is better, and sealing is the line contact, it is superior to general face contact, because cylinder places the next door of valve, so therefore unlikely the falling in the cylinder of medium of leaking can not damage cylinder.
