Abstract
The utility model discloses a be applied to the low globular non return device of resistance in the liquid conveying equipment, it mainly includes: lock sleeve, connector, disk seat, single -lobe open formula valve plate and globular valve body soon. In the one end of globular valve body or externally have a disk seat, single -lobe of arranging in the globular valve body of single -point swing joint opens the formula valve plate soon on the disk seat. The utility model discloses can solve that the resistance that traditional check valve exists is big, control is insensitive, overflow that the sectional area is little, the seal is not good, easily leak, extravagant material, technology are complicated, connect many times, with relevant tube coupling is complicated, the connection speed is slow, pleasing to the eye degree technical problem such as well.
Description
Technical field
The utility model relates to the spherical check device of a kind of lower resistance be applied in equipment for liquid transportation.
Background technique
Traditional check device is divided into flange inhalation check valve, to folder double-disc swing check valve, to folder single-lobe Swing check valve, to folder Lift check valve, to pressing from both sides butterfly check valve, lug to folder double-disc swing check valve, two flange double-disc swing check valves etc.There is following shortcoming in above check device: 1, relies on spring to control, there is larger resistance, control insensitive.2, valve plate is mid-, reduces over flow area.3, valve body is that straight tube is cylindric, limited flow, profile less attractive.4, by some bolts safety check to be connected with pipeline by the respective two panels flange being arranged on pipeline two ends and to there is bad, the easy leakage of seal, waste material, complex process, repeatedly connect, be connected the technical problems such as complicated, connection speed is slow with associated pipe.
Summary of the invention
The purpose of this utility model is to provide the spherical check device of a kind of lower resistance be applied in equipment for liquid transportation, with solve the resistance that traditional safety check exists large, control insensitive, overflow section amass little, seal is bad, easy leakage, waste material, complex process, repeatedly connect, be connected complexity with associated pipe, the technical problem such as connection speed is slow, aesthetics is bad.
In order to realize foregoing invention object, the technological scheme that the utility model adopts is as follows:
The spherical check device of lower resistance, it mainly comprises: lock sleeve, connecting body, valve seat, single-lobe rotary-open type valve plate and ball valve; In or beyond one end of ball valve, be equipped with valve seat, on valve seat, single-point is flexibly connected a single-lobe rotary-open type valve plate be placed in ball valve.
The shape of valve body be cylindric, square or coniform in one.
By lock sleeve, valve body, connecting body are connected with pipeline, form a connecting overall.
Be connected with pipeline by the valve body of welded flange, form a connecting overall.
By buckle, valve body is connected with pipeline, forms a connecting overall.
The advantages such as the utility model has lower resistance, overflow section is long-pending greatly, flow is large, it is sensitive to control, good leak tightness, No leakage, saving material, technique is simple, connection speed is fast, beautiful shape.
Accompanying drawing explanation
Fig. 1 is the utility model lower resistance spherical check device structure front sectional view.
Fig. 2 is the sectional view along A-A direction of Fig. 1.
Number in figure: 1. lock sleeve, 2. connecting body, 3. valve seat, 4. single-lobe rotary-open type valve plate, 5. ball valve.
Embodiment
Specific embodiment of the utility model is see shown in Fig. 1,2.Be applied to the spherical check device of lower resistance in equipment for liquid transportation, it mainly comprises: lock sleeve 1, connecting body 2, valve seat 3, single-lobe rotary-open type valve plate 4, ball valve 5.
In or beyond one end of ball valve 5, be equipped with valve seat 3, on valve seat 3, single-point is flexibly connected a single-lobe rotary-open type valve plate 4 be placed in ball valve 5.
Described valve body is spherical, cylindric, square or coniform.Valve plate is single-lobe rotary-open type valve plate.
The Placement of described valve body and pipeline, for spherical, cylindric, square or cone shape valve body, connecting body and pipeline to be connected by lock sleeve, forms a connecting overall, shown in Figure 1; Or be connected with pipeline by spherical, cylindric, the square or cone shape valve body of welded flange, form a connecting overall; Or by buckle, spherical, cylindric, square or cone shape valve body is connected with pipeline, form a connecting overall.
