Description
Technical Field
The utility model relates to the technical field of opening and closing valve accessories, in particular to an outdoor opening and closing valve lead screw protection device.
Background
The opening and closing valve is important equipment for controlling water quantity, flow direction and liquid level in a water supply and drainage system, has the function of changing the flow area of a water channel by opening and closing the lifting flashboard through driving a screw rod of the opening and closing valve to rotate left and right by a manual or electric device so as to control the water quantity, the flow direction and the liquid level, and is widely applied.
However, the opening and closing valve switch is in the use, debris, dust appear often in the motion of lead screw and screw pair, lead screw and screw pair wearing and tearing with higher speed, and the opening and closing valve is many in the open air, often adopts and adds lubricating grease to lubricate, and lubricating grease exposes to open air and blows the sun this moment and easily deteriorate and run off, and the lead screw operation also can extrude grease and discharge, is unfavorable for lubricated operation, and the quality of water is also easily polluted to the discharged grease.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the problems that the existing opening and closing valve is easy to wear and short in service life, lubricating grease is easy to deteriorate when exposed and pollutes the environment, and provides an outdoor opening and closing valve screw rod protection device, so that the service lives of the opening and closing valve screw rod and a screw pair are prolonged, the failure rate of the opening and closing valve is reduced, the phenomena of corrosion of the opening and closing valve screw rod and deterioration of the lubricating grease are avoided, and the water quality is protected.
In order to achieve the purpose, the utility model adopts the following technical scheme:
an outdoor opening and closing valve screw rod protection device comprises a gate plate and a base which are matched with each other, wherein a group of supporting seats are fixed on the base, a cross beam is connected onto each supporting seat, a valve seat is fixed on the cross beam, a corresponding through hole is formed in each of the valve seat and the cross beam, a screw pair which faces the through hole is arranged in the middle of each valve seat, a lifting screw rod which is matched with each other is connected into each screw pair, and the lower end of the lifting screw rod penetrates through the through hole to be connected with the gate plate so as to drive the gate plate to lift and open and close through the up-and-down movement of the lifting screw rod in each screw pair;
the part of the lifting screw rod extending out of the screw pair upwards and the part of the lifting screw rod penetrating out of the cross beam downwards are both sleeved with telescopic sleeves so as to protect the exposed part of the lifting screw rod.
Further, the telescopic sleeve is a rubber corrugated pipe.
Further, the through hole is vertically arranged in the middle of the valve seat and the cross beam.
Further, the axis of the lifting screw rod is overlapped with the axis of the through hole, and the bottom end of the lifting screw rod is connected to the middle of the flashboard.
Furthermore, the upper end of the telescopic pipe is connected with the upper end of the lifting screw rod, and the inner diameter of the telescopic pipe is larger than the outer diameter of the lifting screw rod so as not to influence the movement of the screw rod and play a role in protection.
According to the technical scheme, the original exposed opening and closing valve screw rod is wrapped in the telescopic rubber bellows through elastic design, the screw rod is isolated from the outside along with the extension and shortening of the screw rod in the lifting and descending processes of the opening and closing valve, and lubricating grease extruded in the rotation process of the screw rod is wrapped in the screw rod, so that the screw rod cannot fall off to pollute water. The device can ensure that the normal lifting of the opening and closing valve is not influenced, greatly prolongs the service life of the screw rod and the screw pair of the opening and closing valve, reduces the fault rate of the opening and closing valve, is simple and easy to install, reduces the workload of maintainers, and has obvious effect.

Detailed Description
Example 1
In order to make the present invention more clear, the following further describes an outdoor open/close valve screw rod protection device of the present invention, and the specific embodiments described herein are only used for explaining the present invention and are not used to limit the present invention.
Referring to fig. 1, an outdoor opening and closing valve lead screw protection device includes flashboard 1 and base 2 of mutually supporting, its characterized in that:
a group of supporting seats 3 are fixed on the base 2, a cross beam 4 is connected on the supporting seats 3, a valve seat 5 is fixed on the cross beam 4, a corresponding through hole 4a is formed in each of the valve seat 5 and the cross beam 4, and the through holes 4a are vertically formed in the middle of the valve seat 5 and the cross beam 4;
a screw pair 5a facing the through hole 4a is arranged in the middle of the valve seat 5, a lifting screw rod 6 matched with each other is connected in the screw pair 5a, and the lower end of the lifting screw rod 6 penetrates through the through hole 4a to be connected with the flashboard 1 so as to drive the flashboard to lift and open through the up-and-down movement of the lifting screw rod in the screw pair;
