Abstract
The utility model provides a self-operated regulating valve, which comprises a valve body, a valve seat and a valve clack, wherein the valve seat is fixed in the valve body, and a drive cylinder is also arranged in the valve body and is connected with the valve body through a bracket; a piston is arranged in the drive cylinder, and the valve clack is connected with the piston into a whole through a piston rod; the drive cylinder is divided into a left cavity and a right cavity by the piston, the left cavity extends out of the valve body through a pipe fitting to be connected with an inlet of the valve, and a throttle valve is arranged on the pipe fitting; and the right cavity extends out of the valve body through the pipe fitting to be connected with an outlet of the valve, and the throttle valve is also arranged on the pipe fitting. The utility model has the beneficial effects of simple and compact structure, low cost, and is convenient to maintain, and the pressure difference between medium can be used to drive the valve clack to make back and forth movement so as to realize the regulation of system flow and pressure.
Description
Technical field
The utility model relates to a kind of valving, especially is a kind of modulating valve.
Background technique
At present at the modulating valve that is used for regulating system flow and pressure that uses in fields such as metallurgy, petrochemical industry, municipal administrations, general straight-through single seated, straight-through double seat and the form such as telescopic of adopting, the product structure complexity, the cost height, it is inconvenient to safeguard.
Summary of the invention
In order to overcome existing single seated, double seat, telescopic modulating valve product structure complexity, the cost height is safeguarded inconvenient deficiency, and the utility model provides a kind of direct-operated regulator.
The technological scheme that its technical problem that solves the utility model adopts is a kind of direct-operated regulator, comprise valve body, valve seat, flap, valve seat is fixed in the valve body, one drive cylinder also is housed in the valve body, drive cylinder connects by carriage and valve body, one piston is housed in the drive cylinder, flap connects in aggregates by piston rod and piston, drive cylinder is divided into left chamber and right chamber by piston, chamber, a left side is stretched out valve body by pipe fitting and is linked to each other with the import of valve, one throttle valve is housed on the pipe fitting, and right chamber is stretched out valve body by pipe fitting and is linked to each other with the outlet of valve, and a throttle valve also is housed on the pipe fitting.
The beneficial effects of the utility model are simple and compact for structure, and cost is low, and are easy to maintenance, lean on the pressure difference of medium to drive the adjusting that the flap back and forth movement is realized flow system flow and pressure.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the tectonic maps of present embodiment
Fig. 2 is the right elevation of Fig. 1
Among the figure: 1. valve body; 2. valve seat; 3. flap; 4. drive cylinder; 5. piston rod; 6. piston; 7. carriage; 8. pipe fitting; 9. throttle valve.
Embodiment
As depicted in figs. 1 and 2, a kind of direct-operated regulator comprises valve body 1, valve seat 2, flap 3, and valve seat 2 is fixed in the valve body 1, and a drive cylinder 4 also is housed in the valve body 1, and drive cylinder 4 connects by carriage 7 and valve body 1, and carriage 7 is a hollow structure, does not influence the medium circulation.One piston 6 is housed in the drive cylinder 4, flap 3 connects in aggregates by piston rod 5 and piston 6, drive cylinder 4 is divided into left chamber and right chamber by piston 6, chamber, a left side is stretched out valve body 1 by pipe fitting 8 and is linked to each other with the import of valve, one throttle valve 9 is housed on the pipe fitting 8, right chamber is stretched out valve body 1 by pipe fitting 9 and is linked to each other with the outlet of valve, and a throttle valve 9 also is housed on the pipe fitting 8.Between piston 6 and the drive cylinder 4, pass through seal with O ring between piston rod 5 and the drive cylinder 4.
The left chamber of drive cylinder 4 links to each other with outlet with the import of valve respectively by pipe uncle 8 with right chamber, pressure difference by system itself drives flap 3 back and forth movements, realize the automatic adjusting of flow system flow and pressure, the speed that flap 3 comes and goes may be regulated by throttle valve 9.
