Abstract
The utility model relates to a check valve, in particular to the check valve which is not limited by an assembly angle and is not influenced by negative pressure, and is convenient to repair. The check valve comprises a valve body and a diaphragm; horizontal partition plates are arranged in the middle of the valve body; and the surfaces of the plates are provided with through holes and connected with the diaphragm, so the one-way control of water flow is realized. The check valve has a simple structure, is not limited by the assembly angle and is not influenced by the negative pressure of the water flow, and can be connected with various pipe fittings.
Description
Technical field
The utility model relates to valve, relates in particular to a kind of one-way valve that not influenced by negative pressure.
Background technique
Solar water heater should dispose one-way valve usually with the storage water supply container, otherwise meets tap water in the injecting process when forcing down, and water will reverse backflow; The one-way valve that existing market is used for water has: the one, through establishing boss and being hinged on the disk spool on another boss, realize the unidirectional control of current, and the 2nd, connect catch through establishing on end seat, spring, the bar; Realize the unidirectional control of current, the former needs the parallel vertical configuration, no matter latter's arrangement angles; Common defects one is that influenced by negative pressure bigger, the 2nd, and easy to failure, and can not repair; The 3rd type is through establishing sphere or tubular spool, realizes the unidirectional control of current, and this type one-way valve is longer working life; But need arranged perpendicular, influenced by certain negative pressure.
The model utility content
The utility model no matter purpose is to provide a kind of arrangement angles, is not influenced by negative pressure to above-mentioned condition; Working life is longer, even the malfunctioning one-way valve that also can conveniently repair is characterized in that; Connecting thread is established at the valve body two ends, and diaphragm is established in the centre, and the plate face is uniformly distributed with several through holes; Center hole connects the software diaphragm, realizes the unidirectional control of current.
A kind of one-way valve is characterized in that, described connecting thread one end is an internal thread, and the other end is an outside thread, and diaphragm is established in the internal and external threads connecting part.
A kind of one-way valve is characterized in that, described diaphragm is the slightly curved disk of end face, is the plane below, and the planar central place establishes cylindrical rib, establishes the taper knot that the tail end diameter is slightly less than the upper end in the middle of the rib.
A kind of one-way valve, described diaphragm are software, edge thickness 0.5-1.2 millimeter, interior thickness 1.5-3 millimeter.
The technological scheme of the utility model is
The utility model comprises valve body and diaphragm, and valve body one end is established internal thread, and the other end is established outside thread; Diaphragm is established in the internal and external threads connecting part, and the plate face is uniformly distributed with several through holes, and the software diaphragm is a disc; End face is camber slightly, is made as the plane below, and the planar central place establishes cylindrical rib; Establish the taper knot that tail diameter is slightly less than the upper end in the middle of the rib, be connected in the female end, realize the unidirectional control of current through center hole on the plate face.
The utility model is simple in structure, not limited by arrangement angles, not influenced by the current negative pressure, can be connected with multiple pipe fitting.
Description of drawings
Fig. 1 is the structural representation of the utility model, and Fig. 2 is the plan view of Fig. 1.
1 is to establish internal thread interface, the 2nd among Fig. 1, diaphragm, the 3rd, and male connection, the 4th, diaphragm, the 5th, rib and taper knot, 6 is through holes among Fig. 2.
Embodiment
The utility model comprises valve body and diaphragm 4, and valve body one end is established internal thread interface 1, and the other end is established male connection 3; Diaphragm 2 is established in the internal and external threads connecting part, is uniformly distributed with several through holes (Fig. 2) 6 on the plate face, and the software diaphragm is a disc 4; The planar central place establishes rib 5; Establish taper knot 5 in the middle of the rib, rib 4 in internal thread 1 end on the diaphragm 2 center hole pass, be close on 2 of the diaphragms through taper knot 5 planes diaphragm 4.
The utility model connects to flow to internal thread 1 end from male end 3 to be controlled.When current when the through hole 6, hydraulic pressure make diaphragm 4 edges break away from through hole 6 and obtain through, when water flow pressure during less than reverse negative pressure, diaphragm edge blocks through hole, realizes the unidirectional control of current.
Claims (4)
1. one-way valve, connecting thread is established at the valve body two ends, it is characterized in that, establishes diaphragm in the middle of the valve body, is uniformly distributed with several through holes on the plate face, and center hole connects the software diaphragm, realizes the unidirectional control of current.
2. a kind of one-way valve according to claim 1 is characterized in that, described connecting thread one end is an internal thread, and the other end is an outside thread, and diaphragm is established in the internal and external threads connecting part.
3. a kind of one-way valve according to claim 1 is characterized in that, described diaphragm is the slightly curved disk of end face, is the plane below, and the planar central place establishes cylindrical rib, establishes the taper knot that the tail end diameter is slightly less than the upper end in the middle of the rib.
4. a kind of one-way valve according to claim 1, described diaphragm are software, edge thickness 0.5-1.2 millimeter, interior thickness 1.5-3 millimeter.
