Abstract

The utility model relates to a tube pressure self-assist start-close valve, belonging to the check valve technical field, which comprises a valve body provided with a valve body inlet and a valve body outlet. The tube pressure self-assist start-close valve is characterized in that the valve body is provided with a tube pressure self-assist device. The utility model controls the discharge and charge of the liquid in the middle valve chamber to utilize tube pressure to automatically start and close the valve, having low cost, simple operation, saved time, saved force and fast response. The tube pressure self-assist start-close valve can stop various fluids, while the stop effect can be increased along with the increase of the fluid pressure and the volume increase of the valve body.

Description

Pipe is pressed from the power-assisted opening/shutting valve
Technical field
The utility model belongs to the stop valve field, is specifically related to a kind of pipe and presses from the power-assisted opening/shutting valve.
Background technique
The stop valve of current use, can be divided into artificial valve, electric valve, hydraulic valve by mode of operation, artificial valve is generally realized the switch of valve by the rotation hand wheel rotating screw bolt, when big or manifold pressure is big when valve, bothersome effort during operation, use inconvenience, electric valve and hydraulic valve adopt motor or oil hydraulic cylinder to realize the switch of valve, involve great expense.
Summary of the invention
The purpose of this utility model provides the pipe that a kind of cost is low, pressure power-assisted realization valve opening and closing is managed in utilization and presses from the power-assisted opening/shutting valve.
The utility model is achieved through the following technical solutions:
Be that a kind of pipe is pressed from the power-assisted opening/shutting valve, comprise valve body, valve body is provided with valve body import, valve outlet, it is characterized in that valve body is provided with pipe and presses from power assisting device.
Described pipe is pressed middle valve pocket airtight in power assisting device comprises valve body, middle valve pocket is provided with the intake pipe that is communicated with the valve body import, the outlet pipe that is communicated with valve outlet, described outlet pipe is provided with reduction valve, the low pressure control valve that discharges water, described outlet pipe is provided with the control diaphragm, and the control diaphragm is connected with inlet valve on the intake pipe by connecting rod.
According to the Environmental Conditions difference, can establish tubulose plastic cement spool in the middle valve pocket, also can establish piston or leather cup.When establishing tubulose plastic cement spool in the middle valve pocket, tubulose plastic cement spool is provided with the lever-like chuck, and described lever-like chuck is fixed on the inwall of middle valve pocket; When establishing piston or leather cup in the middle valve pocket, the bottom of piston or leather cup is provided with self-closing valve gap.
The utility model charges and discharge by control intervening valve intracavity liquid, utilizes pipe to press the keying that realizes valve automatically, and it is low, simple to operate, time saving and energy saving to have a cost, willing advantage.The utility model goes for ending of various fluids, and the pressure of fluid is big more, and valve body is big more, and effect is remarkable more.The claimant applied on December 9th, 2005, patent No. ZL200520125825.2, name is called the rubber membrane in the patented technology of split gas control running water valve because pressurized is fragile, uses the utility model that it is transformed, can overcome its defective, reach better effect.
Description of drawings
Fig. 1 is the utility model embodiment 1 a structural representation;
Fig. 2 is the utility model embodiment 2 a structural representation.
As shown in FIG.: 1 valve body, valve pockets in the middle of 2,3 tubulose plastic cement spools, 4 lever-like chucks, the 5 low pressure control valve that discharges water, 6 outlet pipes, 7 reduction valve, 8 control diaphragms, 9 inlet valves, 10 intake pipes, 11 pistons, 12 self-closing valve gaps.
Embodiment
Embodiment 1
As shown in Figure 1, being provided with pipe in the valve body 1 presses from power assisting device, described pipe is pressed middle valve pocket 2 airtight in power assisting device comprises valve body 1, be provided with tubulose plastic cement spool 3 in the middle valve pocket 2, the tubulose plastic cement spool 3 outer lever-like chucks 4 that are provided with the rigid plastics making, middle valve pocket 2 is provided with the intake pipe 10 that is communicated with valve body 1 import, the outlet pipe 6 that is communicated with valve body 1 outlet, described outlet pipe 6 is provided with reduction valve 7, the low pressure control valve 5 that discharges water, described outlet pipe 6 is provided with control diaphragm 8, and control diaphragm 8 is connected with inlet valve 9 on the intake pipe 10 by connecting rod.
When the utility model need be driven valve, open the low pressure control valve 5 that discharges water, the liquid in the middle valve pocket 2 flow into valve bodies 1 outlet through reduction valve 7 decompression backs by outlet pipe 6, meanwhile, outlet pipe 6 internal pressures descend, control diaphragm 8 shrinks, and drivening rod is closed intake pipe 10 by inlet valve 9, liquid in the middle valve pocket 2 can not get replenishing, pressure in the middle valve pocket 2 descends, and the liquid of valve body 1 import struts tubulose plastic cement spool 3, finishes out valve events.
