Abstract
The utility model discloses a novel ball type one-way check valve. The novel ball type one-way check valve comprises a valve body (1), a water outlet (2), a water inlet (3) and the like, and is characterized in that: the water outlet (2) is communicated with the water inlet (3); a valve plug baffle plate (5) which is horizontally connected to the section of the valve body (1) is arranged in the valve body (1) to ensure that water flow can normally run from the water inlet (3) to the water outlet; and when the water flow runs in a reverse direction, a ball type valve plug (4) is pushed by the force of the water flow to the water inlet (3), so the check function is realized. The novel ball type one-way check valve has the advantages that: the valve plug baffle plate (5) is directly welded in the valve body (1) horizontally, and is contacted and matched with one surface of the ball type valve plug (4); and although the novel ball type one-way check valve has a simple structure, the novel ball type one-way check valve has good sealing performance. The design of the ball type valve plug (4) improves the problem that a valve clack of the conventional check valve is easily damaged after used for a long time, the ball type design reduces fluid friction, the sealing performance of a contact surface is improved, and the service life of the valve is prolonged.
Description
Technical field
The utility model relates to a kind of safety check, relates in particular to a kind of novel ball formula one way stop peturn valve.
Background technique
Safety check is meant and relies on medium itself to flow and automatic open and close flap, is used for preventing the valve that medium flows backwards, and claims check valve, one-way valve, reflux valve and back pressure valve again.Safety check belongs to a kind of automatic valve, and it mainly acts on is to prevent that medium from flowing backwards, preventing pump and drive motor counter-rotating, and the releasing of vessel media.Safety check also can be used for possibly rising to the auxiliary system of pressing above system to wherein pressure to be provided on the pipeline of supply.Safety check mainly can be divided into Swing check valve (according to the center of gravity rotation) and Lift check valve (moving along axis).The bottom valve of water pump suction pipe commonly used also belongs to the safety check class in the industry.Have the safety check ubiquity complex structure that is used for fields such as industrial water pump now, the flap cracky, the non-return performance is not good, and the life-span is than problems such as weak points.
Summary of the invention
For solving above technical problem, it is a kind of simple in structure that the utility model provides, and volume is little; Cleaning for ease of maintenaince; The novel ball formula one way stop peturn valve of long service life is made up of valve body (1), water outlet (2), water inlet (3), ball type valve core (4), spool baffle plate (5), it is characterized in that water outlet and water inlet adopt through Placement; In valve body, be provided with one be laterally connected in the valve body cross section the spool baffle plate; Make current can pass through water inlet to the water outlet proper flow, the ball type valve core then is pushed into the water inlet place by current strength when current drive in the wrong direction, and realizes check function.
The beneficial effect of the utility model is: direct transverse weld of spool baffle plate and valve inner, and contact ball type valve core one side is agreed with mutually with the ball type valve core, though simple in structure, favorable sealing property.The design of ball type valve core has improved the problem that the conventional check valves flap uses cracky for a long time, and the design of ball formula has reduced fluid friction power, has improved the surface of contact sealing, has prolonged valve working life.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Embodiment
According to shown in Figure 1, water outlet (2) is directly connected in valve body (1) inside with water inlet (3) with the perforation mode.The spool baffle plate (5) that valve body (1) set inside one laterally connects, and spool baffle plate (5) one side elevations are concave spherical surface, and agree with mutually with ball type valve core (4) in the valve body (1).Valve body (1) the inwall facade of water inlet (3) one sides also is the concave spherical surface shape, and agrees with ball type valve core (4).When current when water inlet (3) flows to water outlet (2), ball type valve core (4) is by spool baffle plate (5) interception, current pass through, the valve proper functioning.Otherwise, when the current adverse current, fluid through the space between spool baffle plate (5) and the valve body (1) to ball type valve core (4) applied thrust; Ball type valve core (4) moves to water inlet (3) one sides; And agree with water inlet (3) inwall concave spherical surface, reach sealing effect, accomplish check function.
Claims (1)
1. novel ball formula one way stop peturn valve; Constitute by valve body (1), water outlet (2), water inlet (3), ball type valve core (4), spool baffle plate (5); It is characterized in that water outlet (2) and water inlet (3) adopt through Placement, in valve body (1), be provided with one be laterally connected in valve body (1) cross section spool baffle plate (5), make current can pass through water inlet (3) to the water outlet proper flow; Ball type valve core (4) then is pushed into water inlet (3) by current strength and locates the realization check function when current drive in the wrong direction.
