Description

A kind of one-way valve
Technical field
The utility model relates to a kind of valve, particularly a kind of one-way valve.
Background technique
One-way valve controls the unidirectional valve passed through of fluid.Traditional one-way valve relies on elastic element to drive spool to realize reverse closing function, and the pressure that forward then relies on the fluid flowing through one-way valve overcomes the elastic force load of elastic element to open one-way valve.Traditional one-way valve has housing, valve member and spring, is formed with fluid passage and valve seat at housing place, valve member contact valve seat with closes fluid passage and valve member from valve seat separation to open fluid passage, spring exerts a force along valve closing direction to valve member.Traditional one-way valve structures more complicated, and rely on elastic member to realize the two-way flow of limit fluid, required VOP is comparatively large, and valve closing is also rapid not.When hydrodynamic pressure is lower, the more difficult unlatching realizing valve body.And complex structure, manufacturing is more difficult, and cost is higher, and rate of fault is also high.
Because the pressure of fluid may be very low in some application, objectively wish that the cracking pressure of one-way valve is low as far as possible, one-way valve flow resistance can be smaller.But, the one-way valve that cracking pressure is low, the elastic force of reverse closedown is also little, closing process needs the time more grown, also to ensure that outlet pressure is higher than inlet pressure to could reliable sealing during certain numerical value simultaneously, and closing process one-way valve faster, the cracking pressure often needed is high.In order to overcome this problem, the most complex structure of existing one-way valve, cost are high.
Model utility content
The utility model provides one can be applicable to low-pressure fluid for solving in known technology the technical problem that exists, and can be applicable to again the one-way valve of high-pressure liquid, this one-way valve structures is simple, cost is low.
The technological scheme that the utility model is taked for the technical problem existed in solution known technology is: a kind of one-way valve, comprise the upper valve body and lower valve body that are threaded connection, bottom in described upper valve body is provided with deck, between described deck and the upper end of described lower valve body, be clamped with restriction net; Lightweight spheroid is provided with in described lower valve body, undergauge section and connected path section is provided with in the underpart of described lower valve body, in described undergauge section, be formed with the valve seat construction with described lightweight spheroid form adaptation, the surface of described valve seat construction is connected with rubber pad; Be provided with internal thread in the upper end portion of described upper valve body, the path section of described lower valve body is provided with internal thread.
Be provided with in the upper end portion of described upper valve body and the underpart laterally zygomorphic undergauge section of described lower valve body and connected path section, the upper end portion internal thread of described upper valve body is arranged in the path section of described upper valve body.
The advantage that the utility model has and good effect are: be threaded connection fixing, by the keying of the rise and fall control valve of lightweight spheroid, reach the unidirectional object passed through of fluid.Structure is simple, and cracking pressure is lower, and closing process is also very fast, and failure rate is low, valve body effect is sensitiveer.Both be applicable to low-pressure fluid, be applicable to high-pressure liquid again.Cost is lower, is easy to promote.

Embodiment
For summary of the invention of the present utility model, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1 ~ Fig. 2, a kind of one-way valve, comprise the upper valve body 1 and lower valve body 3 that are threaded connection, the bottom in described upper valve body 1 is provided with deck, is clamped with restriction net 2 between described deck and the upper end of described lower valve body 3; Lightweight spheroid 5 is provided with in described lower valve body 3, undergauge section and connected path section is provided with in the underpart of described lower valve body 3, in described undergauge section, be formed with the valve seat construction with described lightweight spheroid 5 shape adaptation, the surface of described valve seat construction is connected with rubber pad 4; Be provided with internal thread in the upper end portion of described upper valve body 1, the path section of described lower valve body 3 is provided with internal thread.
In the present embodiment, be provided with in the upper end portion of described upper valve body 1 and the underpart laterally zygomorphic undergauge section of described lower valve body 3 and connected path section, the upper end portion internal thread of described upper valve body is arranged in the path section of described upper valve body 1.
Working principle of the present utility model:
Refer to Fig. 3, fluid enters from lower valve body 3, and lightweight spheroid 5 rises under the pressure of fluid and the comprehensive function of buoyancy, and be separated with rubber pad 4, valve is opened, and fluid circulates, and flows out from upper valve body 1.Under the continuation effect of fluid, lightweight spheroid 5 rises until be limited net 2 and stop, and fluid passes through one-way valve.Refer to Fig. 4, if fluid enters from upper valve body 1, then lightweight spheroid 5 is under gravity and the comprehensive function of fluid impulse force, by being pressed on rubber pad 4 tightly, the two is combined closely, and realizes sealing, now fluid is not by, closed check valve, achieves and controls the unidirectional object passed through of fluid.Upper valve body 1 and lower valve body 3 are connected and fixed by internal thread and outer tube.
Although be described preferred embodiment of the present utility model by reference to the accompanying drawings above; but the utility model is not limited to above-mentioned embodiment; above-mentioned embodiment is only schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; do not departing under the ambit that the utility model aim and claim protect, can also make a lot of form, these all belong within protection domain of the present utility model.
