Abstract
The utility model belongs to the technical field of the water conservancy project, concretely speaking, relating to an automatic non-return drainpipe. The utility model contains a valve, a floating ball in the valve and an inlet pipe and an outlet pipe which communicate with the valve. The floating ball is connected with an inner cavity wall of the valve by a connecting rope. The movement range of the floating ball is that the floating ball moves towards the inlet pipe until a nozzle of the inlet pipe is stopped up and moves towards the outlet pipe until the nozzle of the outlet pipe has a clearance. The junction surface of the inner cavity of the valve and the nozzle of the inlet pipe and the outlet pipe is a smooth rotating curved surface. The utility model has a simple structure and convenient installation and maintenance, ensuring the safety of a canal lining plate and avoiding the seepage of the water in canal. The utility model can also make the ground water outside of the canal flow into the canal conveniently. The small engineering quantity of excavation earthwork and backfill earthwork makes the utility model economical and practical. Because of the special drain action, the utility model can be applied to some interrelated engineering field, of which the water table needs to be controlled.
Description
The utility model belongs to the hydraulic engineering technical field, specifically refers to a kind of automatic one-way formula waste pipe.
General big or middle canal for water conveyance is because landform, geologic structure and complicated hydrogeological conditions are changeable.The outer level of ground water of canal comes and go along the channel axis, in some excavation canal section,, surpass at the bottom of channel water position or the canal because level of ground water is higher, in normal utilization or under the channel water position rapid drawdown situation, the concrete lining facing plate of channel will be subjected to the jacking of buoyancy force of underground water and destroy.If common waste pipe is set, can reach outer underground water level of canal and channel water bit synchronization, effectively guarantee canal lining plate purpose of safety, but the outer underground water level of canal is subjected to the influence of various factors, changes over time, be not to keep a kind of stable state, be higher than in the channel water position under the situations such as level of ground water, level of ground water reduction, all can cause channel water to replenish, cause the filter loss of ditch water flow to phreatic.Precious water resource is run off.Therefore, must manage to reduce the outer underground water level of canal, and will guarantee that when underground water level is higher than the channel water position water flows in the canal outside canal, when underground water level is lower than the channel water position, the channel water loss of not exosmosing.Hydraulic engineering at present generally adopts reverse-stop type header tank and supporting facilities such as outlet pipe to reduce the outer level of ground water of channel, be provided with collecting chamber and check valve in the reverse-stop type header tank, collecting chamber combines with water collecting equipment, by outlet pipe with ground water discharge in channel.Check valve is in channel under the effect of external water pressure difference.Realize that the current folk prescription is to flowing in the canal outside canal.Because the collecting chamber build is big, structure is comparatively complicated, and auxiliary facility is many, so construction and excavation and backfill volume of earthwork are big, the civil works investment is big.The critical hydraulic pressure difference that the most important thing is this check valve action unlatching is bigger, needs bigger differential water pressures that check valve is started.In the canal engineering of level of ground water control ratio, can not satisfy the engineering design requirement than strictness.And the water outlet pipe range, after the generation silting, inconvenient maintenance.If adopt this drainage means, just must thicken the canal lining plate, the weight of dependence liner plate overcomes phreatic buoyancy jacking and satisfies the engineering design requirement.This way is very uneconomical.
The purpose of this utility model is to provide a kind of simple in structure, installation and maintenance convenient and can guarantee when underground water level is higher than the channel water position, water flows in the canal outside canal, when underground water level is lower than the channel water position, the automatic one-way formula waste pipe that channel water does not exosmose and the canal lining plate is avoided damaging.
The purpose of this utility model is achieved in that a kind of automatic one-way formula waste pipe, and it comprises valve body, is positioned at the ball float of valve body and intake pipe and the outlet pipe that is connected with valve body.Ball float is connected on the body cavity wall by bridle line, the moving range of ball float in valve body is: move to the intake pipe mouth of pipe to the intake pipe direction and block, move to the outlet pipe mouth of pipe gappedly to the outlet pipe direction, the link surface of the body cavity and the intake pipe mouth of pipe and the outlet pipe mouth of pipe is smooth surface of revolution.
Described body cavity is a ball-type, is fitted with filter screen on the outlet pipe.
The utility model has increased a valve body on the basis of existing normal discharge pipe.The link surface of the body cavity and the intake pipe mouth of pipe and the outlet pipe mouth of pipe is smooth surface of revolution.Ball float in the valve body is connected on the body cavity wall by bridle line, the range of movement of ball float in valve body is: move to the intake pipe mouth of pipe to the intake pipe direction and block, move to the outlet pipe mouth of pipe gapped to the outlet pipe direction, make the current can only be from the unidirectional inflow outlet pipe of intake pipe, thereby guaranteed when underground water level is higher outside the channel, the outer water of canal can flow in the canal, and when water level was higher in the channel, channel water did not exosmose.And the utility model is simple in structure, and installation and maintenance are convenient, and earth excavation and backfill volume of earthwork are little, economical and practical, and it is little that the critical head difference is opened in check valve action simultaneously, can guarantee effectively that the canal lining plate avoids the outer phreatic uplift pressure of canal and destroy.
Describe in detail below in conjunction with drawings and Examples
Fig. 1 is the utility model structural representation
By shown in Figure 1, a kind of automatic one-way formula waste pipe, it comprises valve body 1 and the intake pipe 4 and the outlet pipe 5 that are connected with valve body 1, valve body 1 inner chamber is a ball-type, the link surface of valve body 1 inner chamber and the intake pipe mouth of pipe and the outlet pipe mouth of pipe is smooth surface of revolution, ball float 2 in the valve body 1 is connected on the inwall of valve body 1 by connecting rope 3, and the moving range of ball float 2 in valve body 1 is: move to intake pipe 4 directions intake pipe 4 mouths of pipe are blocked, move to the outlet pipe mouth of pipe gapped to outlet pipe 5 directions.During use, intake pipe 4 is linked in canal to catchment outward on the hidden pipe, outlet pipe 5 is connected with channel, when underground water level is higher outside the canal, catchment outward collection is got in the hidden pipe underground water of canal can be pushed ball float 2 open by intake pipe 4 and enters valve body 1,, equal with water level outside the canal from the gap between the valve body 1 and the outlet pipe mouth of pipe until the channel water position through in outlet pipe 5 canalizes; When water level was higher in the channel, the water in the channel flowed into valve body 1 through outlet pipe 5, then promotes ball float 2 the intake pipe mouth of pipe is blocked, thereby prevented exosmosing of channel water.In order to prevent that the silt in the channel from flowing in the valve body 1 with water, on outlet pipe 5, be fitted with filter screen 6, filter screen 6 can regularly be pulled down cleaning.
