A central nut 13 is inserted into the shaft part of the hand wheel 10; the central nut 13 and the hand wheel are fixed through a locking nut 11; a bearing 12 is sleeved outside the central nut, and the central nut is fixed on the support frame through the bearing; under the effect of bearing, the hand wheel can not receive the restriction of support frame around the axial region rotation to can drive central nut and rotate, and realize the switching of valve. The central nut is in an inverted T shape; the lower end of the central nut is clamped on the bearing, and the inverted T-shaped central nut can be clamped on the support frame to prevent the central nut from slipping. A screw 14 is arranged in the central nut 13, the central nut is in threaded fit with the screw, and when the central nut is influenced by a hand wheel to rotate, the screw can be driven to rotate together, so that the screw can move up and down;
A clamping groove is formed in the outer side of the valve body; the lower part of the support frame is provided with a buckle 7; the buckle is clamped in the clamping groove, and the buckle is not a narrow buckle but a wide clamping piece with a clamping function, such as a semi-open ring and the like; compared with the prior patent application, the utility model is characterized in that the support frame and the valve body are mutually clamped, but the support frame and the pressing sleeve type valve cage are not fixed, so that the acting force on the support frame can be favorably transmitted to the valve body for reduction, and the pressure born by other parts is reduced; such as: when the valve is closed, the valve rod moves downwards, the valve rod can be subjected to upward reaction force certainly, the reaction force can be transmitted to the support frame along the valve rod and the screw rod, if the support frame is not clamped with the valve body, the support frame can move upwards under the action of the reaction force, the closing of the valve can be counteracted, the closing of the valve is influenced, after the support frame and the valve body are clamped together, the reaction force can be transmitted to the valve body, the valve body is used for bearing the reaction force, the advantages of the valve are that the pressure borne by other components of the valve is reduced, and the normal closing of the valve can not be influenced; a stop screw 6 is arranged between the valve body and the support frame, and the stop screw can ensure that the support frame is firmly fixed on the valve body.
The lower end of the screw 14 is inserted into the automatic compensator 15; a stop block 16 is fixedly connected to the outer side of the automatic compensator 15, is positioned on the outer side of the support frame, and has a length greater than or equal to the width of the support frame, so that the stop block cannot rotate and can move up and down, and the automatic compensator cannot rotate; the lower end of the automatic compensator 15 is provided with a valve rod 21; the lower end of the valve rod 21 is provided with a valve core 4; the valve core 4 is inserted in the valve body 1; as shown in fig. 3, the automatic compensator includes a connection housing 22 and a disc spring 23; the connecting outer sleeve is sleeved outside the disc spring; the disc spring 23 is fixedly arranged between the screw rod and the valve rod; the connecting outer sleeve is fixedly connected with the screw rod, and the connecting outer sleeve can be driven to move together when the screw rod descends or ascends; a clamping piece 24 is arranged between the connecting outer sleeve and the valve rod, and when the connecting outer sleeve rises, the clamping piece can drive the valve rod to rise.
The compensating action of automatic compensator comes from the dish spring, no matter the valve is electronic, pneumatics or still surges, because the error of stroke location and moment location, in addition mechanical wear, all can lead to the not tight situation of valve seal, consequently the utility model discloses set up the dish spring, rely on the elastic deformation of dish spring to provide the pressure output that lasts for the case to can guarantee that the shutoff of case is effectual.
As shown in FIG. 2, the press sleeve type cage is disposed outside of the valve stem; the press sleeve type valve cage comprises a packing press sleeve 17, a press cover 19 and a press sleeve 5; the pressing sleeve 5 is positioned inside the valve body; the lower end of the pressing sleeve is provided with a sealing seat 2 matched with the shape of the valve core; a sealing gasket 3 is arranged between the sealing seat 2 and the valve body; the upper end of the pressing sleeve is provided with a pressing cover 19; a flange 18 is arranged on the outer side of the gland, a bolt 8 is arranged in the flange, and the gland is fixedly connected with the valve body through the bolt; the inner side of the gland is provided with a filler 20; the upper end and the lower end of the filler are both provided with a filler pressing sleeve 17. The valve seat of traditional valve is the different materials of build-up welding on the body, then processes out the valve seat, but has the welding degree of difficulty and the shortcoming of being difficult to dismantle, change. The pressing sleeve type valve cage enables the sealing seat to be an independent part, and the sealing gasket 3, the sealing seat 2, the pressing sleeve 5 and the valve body 1 can be integrated under the action of the pressing sleeve type valve cage, so that the difficulties of welding and processing are overcome, the valve sealing effect is good, and the valve is simple and convenient to maintain.
the utility model discloses a theory of operation does:
1) When the valve is closed: rotating the hand wheel 10 clockwise, the center nut 13 rotates clockwise. The screw 14 and the valve rod 21 are connected together through an automatic compensator 15. The central nut (left-hand thread) rotates clockwise to drive the screw rod (left-hand thread) to move. Due to the action of the stop block, the connecting outer sleeve and the screw cannot rotate and can only move downwards. At this time, the valve stem 21 is also moved downward by the automatic compensator 15. So that the valve element 4 engages the valve seat 2 and the closing of the valve is effected.
2) When the valve is opened: rotating the hand wheel 10 counterclockwise, the center nut 13 rotates counterclockwise. The screw and the valve rod are connected together by an automatic compensator 15. The central nut (left-hand thread) rotates counterclockwise to drive the screw 14 (left-hand thread) to move.
