Abstract
The invention provides a self-operated adjusting valve, which comprises a valve body, a valve seat and a valve flap, wherein the valve seat is fixed in the valve body; a driving cylinder is also arranged in the valve body and is connected with the valve body through a bracket; a piston is arranged in the driving cylinder; the valve flap is connected with the piston into a whole through a piston rod; the driving 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 the pipe fitting is provided with a throttle valve; and the right cavity extends out of the valve body through a pipe fitting to be connected with an outlet of the valve, and the pipe fitting is also provided with a throttle valve. The adjusting valve has the beneficial effects of simple and compact structure, low cost, convenience in maintenance and capability of realizing adjustment of flow rate and pressure of a system by driving the valve flap to reciprocally move by means of pressure difference of a medium.
Description
Technical field
The present invention 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, product structure is complicated, and cost is high, and it is inconvenient to safeguard.
Summary of the invention
In order to overcome existing single seated, double seat, telescopic modulating valve product structure complicacy, cost is high, safeguards the deficiency of inconvenience, and the present invention provides a kind of direct-operated regulator.
The technical solution adopted for the present invention to solve the technical problems is a kind of direct-operated regulator, comprises valve body, valve seat, flap, and valve seat is fixed in the valve body; One drive cylinder also is housed in the valve body, and drive cylinder connects through carriage and valve body, and a piston is housed in the drive cylinder; Flap connects in aggregates through piston rod and piston; Drive cylinder is divided into left chamber and right chamber by piston, and left chamber is stretched out valve body through pipe fitting and linked to each other with the import of valve, and a throttle valve is housed on the pipe fitting; Right chamber is stretched out valve body through 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 invention has the beneficial effects as follows simple and compact for structurely, cost is low, and is easy to maintenance, leans 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
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
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 through 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 through piston rod 5 and piston 6; Drive cylinder 4 is divided into left chamber and right chamber by piston 6, and left chamber is stretched out valve body 1 through pipe fitting 8 and linked to each other with the import of valve, and a throttle valve 9 is housed on the pipe fitting 8; Right chamber is stretched out valve body 1 through 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 through 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 possibly regulated through throttle valve 9.
Claims (1)
