Self-sealing function regulation valve
Technical field
This utility model relates to a kind of fluid control valve, particularly to a kind of self-sealing function regulation valve.
Background technology
Stop valve, is also pipe valve, is installed in pipeline the circulation for control piper medium or cut-off, existing cut-off
Valve includes that valve body, valve rod, valve gap, flap, pressure cap and handwheel, described valve body are provided with the water inlet of medium circulation, outlet, described
Valve body is positioned at water inlet and is additionally provided with valve port at the friendship neighbour of outlet, and described valve gap is located at above valve body, and pressure cap is located on valve gap
Side, described flap can folding be located at valve body on described valve port, one end of described valve rod is solid with flap through pressure cap and valve gap
Even, described handwheel is located on the free end of valve rod, during use, by turn handwheel can the upper and lower sliding of band ovable valve stem thus drive
The flap of valve rod lower end and valve port do opening and closing action, it is achieved the function circulating or ending.Above-mentioned stop valve has the drawback that
1, do not possess check function, it is impossible to prevent the medium in pipeline from flowing backwards, it is impossible to control medium one-way flow, give cut-off
Cleaning and the maintenance of valve are made troubles.In order to prevent the medium in pipeline from flowing backwards, after tap water pipe line installs regulation valve
, check-valves also need to be installed on the pipeline that stop valve outlet is adjacent, due to stop valve and the non-integral structure of check-valves, it is necessary to
It is respectively mounted, operation complexity is installed, time-consuming, laborious, add the joint of pipeline, also improve installation simultaneously and keep in repair into
This, make troubles to workmen, and partial installation check-valves take pipeline location.
2, do not possess filtering function, in order to remove the impurity suspended in pipeline, tap water pipe line installs stop valve
After, also on pipeline adjacent near stop valve, defecator need to be installed, also improve installation and maintenance cost, to constructor
Member makes troubles.
3, the discharge pressure of above-mentioned stop valve is non-adjustable, does not have the effect of decompression, it is impossible to adjust according to actually used situation
The discharge pressure of joint valve port, does not possess the function of water saving.
4, above-mentioned stop valve sealing effectiveness is bad, has used for a long time and water has often occurred from showing that the junction of valve gap with valve body leaks
As.
Utility model content
For the problems referred to above, the utility model proposes a kind of rational in infrastructure, safety is high, good sealing effect, collection non-return, mistake
The self-sealing function regulation valve that filter and water-saving function are integrated.
For solving this technical problem, this utility model takes below scheme: self-sealing function regulates valve, including valve body, valve
Bar, valve gap, driving means, sealing clamp, described valve body be provided with medium circulation water inlet and outlet, described valve body be positioned at into

Improve further: be positioned at the outside of described float disc above valve port in described valve body and be additionally provided with cartridge filter,
The bottom correspondence float disc of described sealing clamp be arranged over compression leg, the bottom correspondence cartridge filter sidewall of described sealing clamp
Position be provided with valve Guan Bi and step down cannelure.
Improve further: described valve body is additionally provided with on the inwall between valve gap and valve port can prevent medium fluid
The sealed cylinder leaked outside, the position of described sealed cylinder correspondence valve body outlet is provided with effluent trough.
Improve further: between described sealing clamp and sealed cylinder, be provided with sealing ring.
By using preceding solution, the beneficial effects of the utility model are: this utility model self-sealing function regulates
Valve has the advantage that
1, be provided with float disc, between float disc and sealing clamp, be provided with check spring, during work fluid by gram
Take the pressure of check spring to wash float disc open so that medium flows out the outlet of valve body at valve port, when the water outlet of valve body
When mouth pressure is more than water inlet pressure, float disc then can firmly be sealed valve by the pressure of the hydraulic pressure of outlet and check spring
Mouthful, thus reaching the function preventing the medium in pipeline from flowing backwards so that medium does one-way flow, water-saving and environmental protection.
2, its simple in construction, it is not necessary to install check-valves on the pipeline that the outlet of regulation valve is adjacent, decrease and be mounted to
This, bring convenience to workmen, be not take up pipeline location.
3, can compress or discharge check spring by the distance between regulation float disc and sealing clamp, thus control
The discharge pressure of valve port, reaches the adjustable purpose of discharge pressure, has the function of decompression and water saving, can be according to actually used situation
The discharge pressure of regulation valve port, very convenient during use, save cost of use and the energy.
4, in valve body, it is positioned at the outside of described float disc above valve port is additionally provided with cartridge filter, so that this practicality is new
Type regulation valve also has the function of filtration, can remove the impurity suspended in pipeline, improve water safety during use.
5, it is additionally provided with, on valve body inwall between valve gap and valve port, the sealed cylinder that can prevent medium fluid from leaking outside,
The sealing effectiveness making this utility model regulation valve is the best, does not haves the water junction leakage from valve gap with valve body during use
Phenomenon.
