Abstract
The utility model relates to a dust collector, in particular to a valve with a rotation-preventing guide device. The valve comprises a valve seat, a valve plate, a lifting rod, a cylinder and the rotation-preventing guide device, the valve plate is connected with the cylinder through the lifting rod, the valve plate and the lifting rod are in threaded connection, and the lifting rod and the cylinder are also in threaded connection. The rotation-preventing guide device is composed of a guide groove and a stop rod, the guide groove is arranged beside the valve plate, one end of the stop rod is fixed on the valve plate, and the other end of the stop rod is limited in the guide groove. The rotation-preventing guide device is added on an existing lift valve and by-pass valve structure, so that effect of preventing the valve plate from rotating is achieved, and the valve is simple in structure and convenient to mount. In addition, the valve plate can be prevented from rotation due to impact of flue gas during operation, stroke of the valve plate is guaranteed beneficially, the valve plate is prevented from falling off due to rotation, and potential risk is reduced accordingly.
Description
Technical field
The utility model relates to a kind of deduster, especially relates to a kind of valve with spline guiding device.
Background technique
Existing deduster poppet valve and by-pass valve, for the ease of maintenance, the dismounting of cylinder and valve plate, adopt and be threaded between valve plate and lifting arm, between lifting arm and cylinder, adopts and be threaded.In running, valve plate is rotated by the impact of flue gas effect, drive lifting arm to rotate simultaneously, cause between being threaded between valve plate and lifting arm, lifting arm and cylinder be threaded loosening, affect the stroke of valve plate, even there is the valve plate situation that drops, have a strong impact on the normal operation of boiler, deduster, even can cause shutdown of boiler.
Summary of the invention
The purpose of this utility model is the shortcoming existing in existing poppet valve, by-pass valve structure, provides improved, can prevent a kind of valve with spline guiding device that valve plate rotates.
The utility model is provided with valve seat, valve plate, lifting arm, cylinder and spline guiding device, and described valve plate is connected with cylinder by lifting arm, between valve plate and lifting arm, adopts and is threaded, and between lifting arm and cylinder, adopts and is threaded; Described spline guiding device is comprised of guiding groove and pin, and described guiding groove is arranged on valve plate side, and pin one end is fixed on valve plate, and the pin the other end is limited in guiding groove.
The utility model increases spline guiding device in existing poppet valve, by-pass valve structure, reaches the effect that prevents that valve plate from rotating, simple in structure, easy for installation.In addition, can prevent that valve plate is subject to flue gas to affect the rotation of generation when operation, be conducive to guarantee the stroke of valve plate, and prevent that valve plate from, because the phenomenon dropping appears in rotation, reducing potential safety hazard.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment's structural representation.
Fig. 2 is that the A of Fig. 1 is to view.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As illustrated in fig. 1 and 2, the utility model embodiment is provided with valve seat 1, valve plate 2, lifting arm 3, cylinder 4, guiding groove 5 and pin 6, described valve plate 2 is connected with cylinder 4 by lifting arm 3, between valve plate 2 and lifting arm 3, adopts and is threaded, and between lifting arm 3 and cylinder 4, adopts and is threaded; Described guiding groove 5 is arranged on valve plate 2 sides, and pin 6 one end are fixed on valve plate 2, and baffle plate 6 the other ends are limited in guiding groove 5, and in Fig. 1, L is the stroke of valve plate 2.
Valve plate 2 is a solidity integral body with pin 6, and valve plate 2 is in up and down process, and it is interior up and down that pin 6 one end are limited at guiding groove 5, reaches the effect that prevents that valve plate 2 from rotating.
