Abstract
The utility model discloses an overflow valve. The overflow valve is characterized in that the overflow valve comprises a valve body, a valve core, a valve rod and an adjusting bolt, wherein the valve core is connected with the valve rod and arranged inside the valve body, a water-in connector is arranged at one side of the valve body, an overflow mouth is formed in the bottom of the valve body, the adjusting bolt is arranged at one end of the valve rod, a spring is arranged on the periphery of the valve rod, the spring moves between the valve core and the adjusting bolt, and a sealing component is arranged between the valve body and the valve core. The overflow valve has the advantages that if a user forgets to cut off a water pump switch or pressure is too large, an overflow valve component is automatically opened because of the pressure, then water flows into a circulation water tank, service life of a water pump and pipeline can not be affected because of increase of the pressure, the adjusting bolt is installed inside the overflow valve component, and the user can adjust the overflow valve according to the practical pressure. The overflow valve is simple in structure, convenient to use and capable of being widely applied.
Description
Technical field
The utility model relates to a kind of relief valve.
Background technique
In dynamometer experimental stand pipeline with cyclic water tank, the spilling water valve member is installed, as the user forget cut off pump switch or pressure excessive, water pump and pipeline will affect the life-span because of increased pressure, impact is used, and has increased cost.Therefore, be badly in need of a kind of improved technology and solve existing this problem in prior art.
Summary of the invention
The purpose of this utility model is to provide a kind of relief valve.
The technical solution adopted in the utility model is:
Relief valve, comprise valve body, spool, valve rod and regulator bolts, described spool is connected with valve rod and is located at valve inner, described valve body one end is provided with water supply connector, described valve body bottom is provided with flow-off, described regulator bolts is located at valve rod one end, and described valve rod is arranged with spring outward, and described spring is active between spool and regulator bolts.
Be provided with Sealing between described valve body and spool.
The utility model has the advantages that: as the user forget cut off pump switch or pressure excessive, the spilling water valve member will be opened automatically due to the pressure of water, water flows into cyclic water tank, water pump and pipeline can not affect the life-span because of increased pressure, and a regulator bolts is housed in the spilling water valve member, and the user can adjust according to actual pressure, and is simple in structure, easy to use, applied widely.
