Abstract
The invention discloses a pipe-explosion self-closing valve, which comprises the following parts: case, spool, valve plate and counterweight. The weight of counterweight can change the adjusting current velocity. When the fluid current velocity is not more than the adjusting current velocity, the pipe-explosion self-closing valve opens. When the fluid current velocity is more than the adjusting current velocity, the pipe-explosion self-closing valve closes automatically and keeps the closing state to avoid the energy waste and damage. When the exploded pipe is restored, the valve returns to the open state. When the main pipe appears the pipe-explosion phenomenon in the multi-source system, the invention can prevent reversing direction pipe-explosion from supplying energy.
Description
Technical field:
The present invention relates to a kind of self-closing valve for tube bursting that constitutes by shell, spool, valve plate, weights.
Background technique:
In the present prior art, be used for the city tap-water pipeline, the switching of the water supply pipe in natural gas line and the house, the valve of natural gas line all is by manual operation, can not automatic-closing valve when booster takes place cut off the water supply, source of the gas, cause the energy to be wasted, cause floods, fire more for the booster place.
Summary of the invention:
Task of the present invention provides a kind of self-closing valve for tube bursting, because this self-closing valve for tube bursting can be according to its measurement result of flow rate of fluid such as tap water, rock gas of flowing through is compared with the flow velocity of adjusting, fluid can not make it close to the impulse force of valve plate when the actual flow velocity that measures when it was not more than and adjusts flow velocity, just stay open state, the normal use to it does not exert an influence, the actual flow velocity that measures when it is when adjusting flow velocity, fluid closes valve plate to the impulse force of valve plate automatically, cuts off the supply to thereafter.The flow velocity of will adjusting adjust normally use flow velocity greater than maximum and less than the booster flow velocity between.When booster did not take place, flow rate of fluid was less than the flow velocity of adjusting, and self-closing valve for tube bursting stays open state.Flow rate of fluid is greater than the flow velocity of adjusting when booster takes place, and self-closing valve for tube bursting is just closed automatically, after closing, the pressure of pressure before its valve plate after greater than valve plate, pressured difference remains on closed condition automatically, cuts off water source or source of the gas to thereafter, has avoided the generation of energy waste and disaster.After booster was repaired, the pressure reduction before and after the valve plate dwindled, and flow rate of fluid is also very little, and valve plate is opened again automatically, gets back to open mode.Self-closing valve for tube bursting of the present invention also has the function of reverse check, and when on the main in multi-source system booster taking place, can prevent oppositely provides the energy to the booster point.
Description of drawings:
Below in conjunction with accompanying drawing the present invention is done into--the explanation in step:
Fig. 1 is a self-closing valve for tube bursting of the present invention---the outward appearance of mechanical type self-closing valve for tube bursting.
Fig. 2 is a self-closing valve for tube bursting of the present invention---the left side view of mechanical type self-closing valve for tube bursting.
Fig. 3 is a self-closing valve for tube bursting of the present invention---the right side view of mechanical type self-closing valve for tube bursting.
Fig. 4 is a self-closing valve for tube bursting of the present invention---the sectional view of mechanical type self-closing valve for tube bursting.What arrow was represented is the direction that fluid flows.
Embodiment:
The basic principle of self-closing valve for tube bursting of the present invention is to judge automatically with the comparative result of flow velocity adjusted according to recording its flow rate of fluid of flowing through, former from line operate.Embodiment has multiple modes such as mechanical type and electrodynamic type.Electrodynamic type is to increase electroprobe, comparator, electric actuator on mechanical basis.Described in the figure is of the present invention a kind of---mechanical type self-closing valve for tube bursting, valve plate have to be measured flow velocity and carries out the function of closing, and weights has the function of the flow velocity of adjusting, and increase and decrease method code weight amount just can change the size of the flow velocity of adjusting.Fig. 1, Fig. 2, Fig. 3, Fig. 4 all do not mark the Placement of size dimension and two ends turnover pipe.This is because of self-closing valve for tube bursting of the present invention both can be used for city tap-water, rock gas main, can be used for again also can be used on other fluid lines such as oil transport pipeline on the tap water, natural gas line in the house.The size dimension of the self-closing valve for tube bursting valve body of invention should adapt with the caliber of the pipeline that is connected.The Placement of its two ends and in-and-out pipe is identical with the Placement of existing valve and pipeline.
Claims (5)
1, self-closing valve for tube bursting mainly is made of shell, spool, valve plate, weights etc.Compare with all kinds of valves that prior art is produced, have the technical characteristics of different internal structure and principle.
2, self-closing valve for tube bursting is characterized in that the import of spool and exports the technical characteristics that can both be lived by the valve plate shelves respectively and close.
3, self-closing valve for tube bursting is characterized in that valve plate can block the technical characteristics of the import or export of spool respectively.
4, self-closing valve for tube bursting is characterized in that flowing into from import when the fluid forward, have only flow velocity just can make when adjusting flow velocity the plate shelves live outlet and be closed, and fluid regardless of the flow rate of fluid size, all can make the valve plate shelves live inlet and pent technical characteristics oppositely when outlet flows into.
5, self-closing valve for tube bursting is characterized in that being provided with weights on the valve plate, is used to adjust the technical characteristics of flow velocity adjusted.
