Description
Technical field
The present invention relates to a kind of ball valves, and in particular to a kind of nonreturn valve core.
Background technique
Hot-water heating, which is very important, takes hot means, and radiator is mounted in a kind of indoor equipment of user, and radiator is
It needs to connect water inlet pipe and drainpipe simultaneously, the water after heating is subjected to a circulation every time, then wait heat dissipation, heat dissipates
After losing a period of time, water circulation is carried out again, and former dispersed heat is heated by boiler backpass, it is such
Mode is comparatively energy saving, for thermostabilization, but in use, has user to usurp the return water discharge in radiator
Either draining pipe crack, water flow loss, causes total heating boiler to be in water compensating state always, at a temperature of moisturizing will lead to
Drop, room temperature can not be promoted, and heat supply, which is less than, needs heat, very unfavorable, for some additional check valves, occupy very much pipeline,
And installation is complicated, and pipe interface is more, and thermal loss is more serious, and check valve is limited by installation site, once it asks
Topic is difficult where investigation to problem.
Summary of the invention
The purpose of the present invention is to provide a kind of nonreturn valve cores, upgrade to traditional spool, both can control opening and closing,
The flow direction of water can also be controlled, not will increase extra pipe fitting, it is easy for installation, it blocks user to use steathily, usurp heat supply water and shadow
The effective temperature of Xiangshui County, multiple moisturizing, the water for covering boiler can drag down original coolant-temperature gage, and need to constantly add
Antirust agent, very waste of resource, a family water, the cool problem in more families can not be solved effectively always.
A kind of nonreturn valve core, including spool, baffle, it is characterized in that the baffle is disc, and in the diameter line of baffle
On symmetrically set there are two shaft；The half of bi-directional symmetrical of the baffle is equipped with groove, the baffle first equipped with two-way groove
The balance for destroying itself, opens and closes baffle, and second utilizes the different characteristics of water impact plane and groove, to protect
Card baffle can be opened and closed；Diameter line in the spool is equipped with axis hole；The baffle can revolve in the vertical direction
On the axis hole being mounted in spool turned, and groove is in baffle shaft top；It is equipped on the left of the baffle of lower half in the spool
Semi-circular strip, being equipped with semi-circular strip on the right side of the baffle of the upper half in spool beat baffle can only unidirectionally for blocking baffle
It opens, additionally it is possible to seal gap between baffle and spool.
Preferably, the spool is spherical valve core.
Preferably, one layer of ring-shaped rubber pad is equipped with around the baffle.
Preferably, not interfere, baffle rotates and is equipped with rounding on the semi-circular strip.
The beneficial effects of the present invention are by a uneven baffle, solves the problems, such as that water valve can not be unidirectionally controlled, subtract
The problems such as few pipe connector, consumptive material, structure is simple, prevents user from usurping, steals the water resource used in hot-water heating, is heating to reduce
The heat that the process of water expends promotes heat stability；In heat supplying process, prevent certain family from pipe burst occurs, user can not
Know at the first time, water route can be prevented to be largely lost with automatic blocking, cause the loss of property and the injury of personnel；Simultaneously also
Hot water can be prevented to be lost in time.

Specific embodiment
As shown, a kind of nonreturn valve core, including spool 1, baffle 2, it is characterized in that the baffle 2 is disc, and
Shaft there are two symmetrically being set on the diameter line of baffle 2；The half of bi-directional symmetrical of the baffle 2 is equipped with groove 2-1, is equipped with double
The balance that itself is destroyed to the baffle 2 first of groove 2-1, opens and closes baffle 2, and second utilizes water impact plane
With the different characteristics of groove 2-1, to guarantee that baffle 2 can be opened and closed,；Diameter line in the spool 1 is equipped with axis
Hole；The baffle 2 is rotatably mounted in the vertical direction on the axis hole in spool 1, and groove 2-1 is in 2 shaft of baffle
Top；Semi-circular strip 3 is equipped in the spool 1 on the left of lower half baffle 2, is equipped with semi-ring in spool 1 on the right side of upper half baffle 2
Shape strip 3 open baffle 2 can only unidirectionally for blocking baffle 2, additionally it is possible to seal gap between baffle 2 and spool 1.
Preferably, the spool 1 is spherical valve core 1.
Preferably, one layer of ring-shaped rubber pad is equipped with around the baffle 2.
Preferably, not interfere, baffle 2 rotates and is equipped with rounding on the semi-circular strip 3.
As shown in figure 5, baffle 2 opens and closes principle：First with the disequilibrium of spool 1 itself, that is, turning
The top half of axis is equipped with groove 2-1, is planar structure in the lower half portion of spool 1；When not being passed through water in spool 1, gear
Piece 2 is to close：Using shaft as symmetry axis, 2 lower half portion of baffle will overweight top half, due to gravity, 2 meeting of baffle
Keep vertical state；When there is water flow from left to right to pass through in spool 1, water flow impacts channel entire in spool 1 everywhere
Power is consistent, but 2 top half of baffle is set as two-sided groove 2-1, and left side water flow can be enhanced to 2 top half of baffle
Impact force makes 2 disequilibrium of baffle, to open；When there is water flow from right to left to pass through in spool 1, baffle 2 has itself
The trend of one closure, while adding the groove 2-1 of 2 top half of baffle, water flow to the impact force of top half greatly and water flow
To the impact force of 2 lower half portion of baffle, baffle 2 can be promoted to be closed, to achieve the purpose that water can only unidirectionally pass through, Jin Erfang
Only user steals and uses, usurps the generation of the problem of water.
The installation of valve body：Valve body with the nonreturn valve core 1 is mounted on to the total loop both ends of heat supplying pipeline, including water inlet
Pipeline and outlet pipeline, when water outflow in the radiator of any user between two valve bodies, which just will form low-pressure area,
At this point, the water of water inlet pipe and water outlet pipe will be concentrated to be flowed to low-pressure area, that is, in boiler due to there is pressure in boiler
Total Water can be lost, and may determine that by boiler liquid level device, and need to only close inlet pipeline valve body can be completed to water at this time
Control when the aqueous reflux of water return pipeline, will trigger the spool 1 closing, and two valve bodies block user's radiator both ends at this time, that
Water between radiator can not outflow, and increase safety guarantee, also can prevent user from usurping the recirculated water in radiator,
Just do not have to frequently feed the recirculated water in boiler in this way, water temperature would not also be absorbed by the water body of resupplies, be dragged down
Whole water temperature is alleviated for thermal pressure, for heating company, if water body Natural Circulation（The case where without make-up water
Under）After time required for supply temperature and financial resources far smaller than inject new water（Script water temperature can absorb heat by new water and draw
Low water temperature, along with scattering and disappearing for heat）Time and financial resources needed for feeding temperature；User also can be timely by Natural Circulation water temperature
Indoor temperature is promoted.
