Abstract
This utility model belongs to for emergency drainage field and in particular to a kind of drainage check valve of high-pressure hose.A kind of drainage check valve it is characterised in that：It includes valve body, valve element, snap joint and discharging valve；Valve element is arranged in the middle part of valve body, and valve body two ends are respectively provided with and can be connected with discharging valve outside valve body with hose connection snap joint, and discharging valve two ends are connected with the valve body of valve element both sides respectively by pipeline.The use of this drainage check valve is the opening/shutting valve (stop valve, gate valve, butterfly valve etc.) in alternative conventional emergency dewatering system, need not manually nurse, manually operate, draining achieves automatic open close, automatic braking anti-backflow in running.The discharging valve installing additional thereon also possesses the function of discharge pipe water, therefore, this drainage check valve：Non-return is automatically reliable, discharges water simple to operate.
Description
Technical field
This utility model belongs to for emergency drainage field and in particular to a kind of drainage check valve of high-pressure hose.
Background technology
China's emergency drainage industry, particularly in the emergency drainage of flooding accident, vigorously promotes the use at present
" high-pressure hose " draining, its drainage system be by：The pipe fittings such as water pump, opening/shutting valve, high-pressure hose, elbow are simultaneously connected by pipe fitting joint
Connect.
Opening/shutting valve in existing drainage system (pipeline), will manually manipulate in drainage system, realize " opening " (draining
When), the effect of " closing " while stopping transport (water pump) pipeline.Market is existing stimulate the menstrual flow more than 150mm, nominal pressure 4.0MPa lock
Its weight of valve, stop valve, at least in more than 140Kg, adds its flange connection it is impossible to enter it with water pump, scupper hose etc.
Row quickly and safely decentralization, connection, certainly will delay rescue time valuable in a large number.If considering further that opening/shutting valve in its work pressure
Artificial operation under power and field condition, even more suffers untold misery.
Valve (stop valve, gate valve, butterfly valve) effect in emergency dewatering system in the past：(1) valve is manually opened：During draining
And after completing draining, the valve needing during water in discharge pipe is open-minded.(2) valve is manually closed：Water pump is stopped transport and (is included water
Pump, the system failure) prevent pipeline backwater, pour in down a chimney.
" portable, the quick peace of safe and reliable, light weight is torn open " is the general requirement to discharge pipe line and its pipe fitting.But, at present
Domestic external enwergy meets simultaneously：Valve and pipe fitting that pressure height (more than 4.0MPa), light weight (light material), snap joint connect
Unique, therefore it is badly in need of can meeting pressure height, light weight, contiguous block in one for the offer of emergency drainage industry is a kind of simultaneously
Drainage check valve.
Utility model content
This utility model is to substitute the opening/shutting valve in current drainage system (gate valve, stop valve etc.) it is intended to exempt
Manually operate, realize automatic open close, valve closing when being automatically performed fault of water pump, stopping transport, prevent sending out of system return refluence
A kind of drainage check valve given birth to and propose.
A kind of drainage check valve it is characterised in that：It includes valve body, valve element, snap joint and discharging valve；Valve element is arranged at
In the middle part of valve body, valve body two ends are respectively provided with and can be connected with discharging valve, discharging valve outside valve body with hose connection snap joint
Two ends are connected with the valve body of valve element both sides respectively by pipeline.
It is removably connected with handle outside valve body；Handle and discharging valve are located at valve body homonymy and handle is located at outside discharging valve
Side；Handle is located at valve body offside with discharging valve.When handle can facilitate drainage check valve to carry and discharging valve can be protected to pull
Collide with, misoperation.
Valve element is butterfly-type bivalve structure.Relatively following several than other versions (single-lobe formula, lift, swing type etc.) have
Individual aspect feature：Structure length is short, volume compact, lightweight；Flap closing velocity is fast, water hangs down, and pressure is little；Easy for installation, water
Flat, vertically；Runner is unobstructed, fluid resistance is little.
The all parts of drainage check valve are all using reflectal material.Light weight, its weight is equivalent specifications valve
/ 10th about (drainage check valves of DN150mm, full weight is not higher than 14Kg), two ends adopt fast connecting joint, for even
Run in water pipeline, pipe fitting, convenient to assemble and disassemble quick, integrates " high, light, fast ", realizes safe and reliable, Quick drainage.
Beneficial effect：Using this drainage check valve be opening/shutting valve in alternative conventional emergency dewatering system (stop valve,
Gate valve, butterfly valve etc.), need not manually nurse, manually operate, draining achieves automatic open close, automatic braking anti-backflow in running.Its
On the discharging valve that installs additional also possess the function of discharge pipe water, therefore, this drainage check valve：Non-return is automatically reliable, discharges water
Simple to operate.
This " drainage check valve " can not only substitute opening/shutting valve (stop valve, gate valve, butterfly valve etc.) in drainage system, realizes
Automatic braking, conveniently discharge water, but also embody its " high (pressure), light (weight), fast (peace is torn open) " superior, for peace
Entirely, reliability, Quick drainage provide technology and ensure.
Brief description
The structural representation of the embodiment one of Fig. 1 this utility model drainage check valve
The structural representation of the embodiment two of Fig. 2 this utility model drainage check valve
The structural representation of the embodiment three of Fig. 3 this utility model drainage check valve
In figure, 1- snap joint；2- handle；3- discharging valve；4- valve body.
Specific embodiment
As shown in figure 1, the structural representation for this utility model embodiment one.A kind of drainage check valve it is characterised in that：
It includes valve body 4, valve element, snap joint 1, discharging valve 3 and handle 2；Valve element is arranged in the middle part of valve body 4, and valve body two ends have respectively
Have and can be connected with discharging valve 3 outside valve body 4 with hose connection snap joint 1, discharging valve 3 two ends pass through pipeline respectively with
The valve body 4 of valve element both sides connects.It is removably connected with handle outside valve body；Handle is located at valve body homonymy and handle position with discharging valve
