Abstract
The utility model relates to a flow controlling valve which comprises a pressure tube, a press cover, a piston, a spring, a valve board, a valve seat and a valve body, wherein the piston, the spring, the valve board and the valve seat are installed in the valve body, the valve board is installed on the valve seat, the spring is installed under the piston and sleeved at the upper part of the valve board, the press cover is installed on the valve body, one end of the pressure tube (1) is connected with the inlet of the valve body, the other end of the pressure tube (1) is communicated with the upper end of the piston, the press cover is installed on the upper end surface of the valve body, and an outlet is arranged on the valve body. When the flow changes, the pressure at a communication part between the pressure tube and the piston also changes, the piston is driven to move vertically under the action of the pressure and the spring, the opening height of the valve board changes, the flow changes as well, thus the automatic adjustment of the flow can be realized, therefore, the utility model has the advantages that the flow can be controlled in time, the transmission requirements can be satisfied, and both the working quality and the automation degree are high.
Description
One, technical field
The utility model is the valve of using on a kind of oil-field flooding pipeline, particularly a kind of flow control valve.
Two, background technology
The valve that uses at present is gate valve, can not control flow, needs artificial changeover valve handwheel when regulating flow, and flow-control is inaccurate, waste time and energy, efficient is low, can not in time regulate flow, do not satisfy the conveying requirement, work quality is not high, and automaticity is low.
Three, summary of the invention
The purpose of this utility model is a kind of flow control valve of design, makes it can regulate flow automatically.
The purpose of this utility model is achieved in that by pressure tube, gland, piston, spring, valve plate, valve seat, valve body to be formed, piston, spring, valve plate, valve seat are installed in the valve body, valve plate is on valve seat, spring is under piston, and spring housing is contained in the top of valve plate, and gland is installed on the valve body, pressure tube 1 one ends and valve body inlet UNICOM, the pressure tube other end and piston upper end UNICOM, gland is installed in the valve body upper surface, and outlet is arranged on the valve body.
The beneficial effects of the utility model are: when flow changes, pressure tube and piston connection position pressure also change, and under pressure and spring action, piston are moved up and down, the valve plate Lift changes, flow also changes, and the realization flow is regulated automatically, therefore, the utility model can in time be regulated flow, satisfy and carry requirement, work quality height, automaticity height.
Four, description of drawings
Accompanying drawing is an assembling schematic diagram of the present utility model.
Five, the specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described.
Embodiment of the present utility model is by being made up of pressure tube 1, gland 2, piston 3, spring 4, valve plate 5, valve seat 6, valve body 7, piston 3, spring 4, valve plate 5, valve seat 6 are installed in the valve body 7, valve plate 5 is on valve seat 6, spring 4 is in piston 3 times, and spring 4 is sleeved on the top of valve plate 5, and gland 2 is installed on the valve body 7, pressure tube 1 one ends and valve body 7 inlets 8 UNICOMs, pressure tube 1 other end and piston 3 upper end UNICOMs, gland 2 is installed in valve body 7 upper surfaces, and outlet 9 is arranged on the valve body 7.
