The utility model discloses convenient operation realizes the adjustment of arbitrary aperture.
Description
Technical Field
The utility model relates to a cylinder, specifically speaking are angle stroke cylinder.
Background
The angle stroke cylinder is mainly used for adjusting the angle valve, and changes a signal into displacement thrust or corner torque by driving the actuating mechanism, so that the aim of controlling the valve to be opened and closed is fulfilled. The angular travel cylinder is used as an actuating mechanism of the valve, and under the action of air pressure, the valve rod is driven by the piston rod to drive the valve core to rotate, so that the valve is opened and closed. The conventional angular stroke cylinder is generally only capable of fully opening or fully closing, and a limit screw structure is provided in the angular stroke cylinder, and the full opening or fully closing operation is performed by the limit screw, so that adjustment of other opening degrees cannot be performed.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides an angle stroke cylinder.
In order to solve the technical problem, the utility model discloses take following technical scheme:
the utility model provides an angle stroke cylinder, includes the cylinder body, and the cylinder body both sides are equipped with the cylinder cap, are equipped with the piston in the cylinder body, the lateral wall of cylinder cap is equipped with stop screw, and stop screw cartridge goes into the cylinder body, and the last cover of stop screw is equipped with the nut, and the nut locking makes stop screw fasten on the cylinder cap.
And a gasket is arranged between the nut and the cylinder cover.
The two nuts are an outer nut and an inner nut, the inner nut compresses the gasket, and the outer nut compresses the inner nut.
When the piston rod in the cylinder body is in a closed state, the limiting screw rod extends into the cylinder body and is in contact with the piston rod.
The number of the limit screws is consistent with that of the piston rods.
The outer nut and the inner nut are the same in size or different in size.
The utility model discloses convenient operation stretches into the change of the length in the cylinder body through adjusting limit screw, realizes the adjustment of arbitrary aperture.

FIG. 1 is a schematic front view of the present invention;
fig. 2 is a partially cut-open schematic view of the present invention.
Detailed Description
For further understanding of the features and technical means of the present invention, as well as the specific objects and functions attained by the present invention, the present invention will be described in further detail with reference to the accompanying drawings and detailed description.
As shown in the accompanying drawings 1 and 2, the utility model discloses an angle stroke cylinder, including cylinder body 1, 1 both sides of cylinder body are equipped with cylinder cap 2, are equipped with piston 7 in the cylinder body 1, the lateral wall of cylinder cap 2 is equipped with stop screw 3, and in 3 cartridges of stop screw were gone into cylinder body 1, the cover was equipped with the nut on the stop screw 3, and nut locking made stop screw fasten on the cylinder cap. The length of the limiting screw rod extending into the cylinder body can be adjusted by loosening the nut, so that the adjustment of different valve opening degrees is realized.
And a gasket 6 is also arranged between the nut and the cylinder cover. The two nuts are an outer nut 4 and an inner nut 5, the inner nut 5 compresses the gasket 6, and the outer nut 4 compresses the inner nut 5. Through interior nut with stop screw and cylinder cap locking connection, the packing ring then is used for bearing the pretightning force of interior nut to the cylinder cap, prevents that interior nut and cylinder cap direct contact from damaging the cylinder cap, and outer nut is used for preventing that interior nut is not hard up to ensure holistic firm installation.
For the length of the limiting screw, the limiting screw is designed according to the stroke cylinders with different sizes and diameters, and when the length of the limiting screw needs to ensure that the stroke cylinders are in a closed state, the limiting screw stretches into the section of one end inside the cylinders and can be in contact with the piston.
The number of the limit screws is consistent with that of the piston rods. Under normal conditions, two pistons are arranged in the angular travel cylinder, a limit screw is correspondingly arranged on each of the cylinder covers on the two sides, and one piston corresponds to one limit screw.
The outer nut and the inner nut are the same in size or different in size.
The utility model discloses in, according to the needs that the valve aperture was adjusted, the length of cylinder body was stretched into to adjustable cylinder body both sides limit screw, revolves out interior nut and outer nut toward the left side, and the rotatory limit screw of accessible can adjust limit screw in cylinder or screw out the cylinder to the length of needs after, with interior nut and outer nut and packing ring to it is tight, with the tight cylinder cap terminal surface of packing ring subsides, the nut is not become flexible for the standard.
It should be noted that the above is only a preferred embodiment of the present invention, and the present invention is not limited to the above, and although the present invention has been described in detail with reference to the embodiments, it will be apparent to those skilled in the art that the technical solutions described in the foregoing embodiments can be modified or some technical features can be replaced with equivalents, but any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
