Abstract
The utility model provides a multifunctional spherical check valve, which makes a spherical check valve and a spherical trip valve reasonably combined together. The outlet part of the valve body of the spherical check valve is provided with a spherical concave part, and the outer side of an end cover of the spherical trip valve is provided with a round which is corresponding to the concave part and is sheathed in the concave part. Two valve bodies are connected into integration through a screw bolt to form a compact combination valve, so that the material is saved and the installation is convenient.
Description
The present invention relates to a kind of safety check, particularly a kind of multifunctional ball-shaped safety check with ball check valve and cut-off valve combination.
At present, using safety check to use the occasion of cut-off valve again, often two kinds of ready-made valves are installed in respectively on the fluid hose, this will seem loaded down with trivial details installing, and making two such valve bodies more simultaneously will waste material.
The purpose of this utility model provides a kind of multifunctional ball-shaped safety check, this a kind of multifunctional ball-shaped safety check is that ball check valve and ball-type cut-off valve are reasonably combined, form a kind of combination brake switch and proporting of compactness, helping saving material, and be convenient to install.
The utility model is to realize like this, be that the utility model provides a kind of multifunctional ball-shaped safety check, this multifunctional ball-shaped safety check has one to have the ball check valve valve body (1) that is roughly oval cavity, the inside of its cavity is provided with a ball sealer (3) and is interval with the water conservancy diversion rib (2) that stops the outlet of ball sealer choke valve body and play guide functions on the peripheral wall of its cavity, combine the seal ring (4) that stops fluid reflux with described ball sealer with being used for of being provided with in the ingress of ball check valve valve body (1), inlet with a ball-type cut-off valve docks described ball check valve valve body in its outlet port, this ball-type cut-off valve has a valve body (14), valve body (14) has a cavity (21) to be used for the pipeline (20) that is connected with other fluid line with one, in described cavity (21), be provided with a spherical seal (11), be provided with seal ring (12) between described cavity (21) and the described pipeline (20), one end of described spherical seal (11) is connected with handle (19) by a valve rod (15), and between described valve rod (15) and valve body (14), pass through valve stem packing (16), valve stem packing trim ring (17) and valve stem packing gland (18) sealing, described spherical seal (11) have one with the consistent through hole of described pipeline (20) caliber, and an end cap with holes (13) is arranged at the inlet of described ball-type cut-off valve, inboard at end cap (13) contacts with described spherical seal (11) by a seal ring (12 '), and end cap directly is sleeved on the described ball-type shut-off valve body (14), when rotating spherical seal (11) by described handle (19) and valve rod (15), can cut off and open pipe (20) in the flowing of fluid, described ball check valve valve body is to dock like this in its outlet port with the inlet of a ball-type cut-off valve, promptly, the export department of described ball check valve valve body has a recess annular and axis centering this ball check valve, the outside of the end cap of ball-type cut-off valve (13) has one with the corresponding circle of described recess and be inserted in described recess, and screw and corresponding bolts by described valve body (1) and valve body (14) are connected as a single entity described ball check valve and ball-type cut-off valve.
Accompanying drawing is the axle sectional view of multifunctional ball-shaped safety check of the present utility model.
As shown in the figure, multifunctional ball-shaped safety check of the present utility model has one to have the ball check valve valve body (1) that is roughly oval cavity, the inside of its cavity is provided with a ball sealer (3) and is interval with the water conservancy diversion rib (2) that stops the outlet of ball sealer choke valve body and play guide functions on the peripheral wall of its cavity, combine the seal ring (4) that stops fluid reflux with described ball sealer with being used for of being provided with in the ingress of ball check valve valve body (1), inlet with a ball-type cut-off valve docks described ball check valve valve body in its outlet port, this ball-type cut-off valve has a valve body (14), valve body (14) has a cavity (21) to be used for the pipeline (20) that is connected with other fluid line with one, in described cavity (21), be provided with a spherical seal (11), be provided with seal ring (12) between described cavity (21) and the described pipeline (20), one end of described spherical seal (11) is connected with handle (19) by a valve rod (15), and between described valve rod (15) and valve body (14), pass through valve stem packing (16), valve stem packing trim ring (17) and valve stem packing gland (18) sealing, described spherical seal (11) have one with the consistent through hole of described pipeline (20) caliber, and an end cap with holes (13) is arranged at the inlet of described ball-type cut-off valve, inboard at end cap (13) contacts with described spherical seal (11) by a seal ring (12 '), and end cap directly is sleeved on the described ball-type shut-off valve body (14), when rotating spherical seal (11) by described handle (19) and valve rod (15), can cut off and open pipe (20) in the flowing of fluid, described ball check valve valve body is to dock like this in its outlet port with the inlet of a ball-type cut-off valve, promptly, the export department of described ball check valve valve body has a recess annular and axis centering this ball check valve, the outside of the end cap of ball-type cut-off valve (13) has one with the corresponding circle of described recess and be inserted in described recess, and screw and corresponding bolts by described valve body (1) and valve body (14) are connected as a single entity described ball check valve and ball-type cut-off valve.
