Description

A kind of swing check valve
Technical field
The utility model is related to valve technology field, specially a kind of swing check valve.
Background technology
The flap of swing check valve is in the form of annular discs, and the rotating shaft around valve base channel rotates, because valve internal channel is into stream Line style, flow resistance are less than lift check valve, it is adaptable to the heavy caliber occasion that low flow velocity and flowing seldom change, but should not use In Pulsating Flow, its sealing property is not as good as lift.Swing check valve point three kinds of single-lobe formula, Double-disc type and most formulas, these three Form is mainly divided by valve aperture, in order to when preventing medium from stopping flowing or flowing backwards, weaken hydraulic blow.
In existing swing check valve, when preventing medium from flowing back, valve disc can be severely affected power, easily broken Split, there is no the effect for adjusting flow.
Utility model content
The purpose of this utility model is to provide a kind of swing check valve, to solve the valve proposed in above-mentioned background technology Disk can be severely affected power, easy fracture and the problem with the effect for adjusting flow.
For achieving the above object, the utility model provides following technical scheme:A kind of swing check valve, including valve body, Valve disc, valve seat, adpting flange, hinge pin, gasket seal, upper lid, adjusting knob, pressure spring, decompressor, pressure gauge and film Piece, the inner chamber of the valve body are inlaid with hinge pin, and the side of the valve disc is provided between valve seat, and valve disc and hinge pin and passes through Connecting rod is connected, and the adpting flange is fixedly connected with the both sides in valve body, the upper lid installed in the top of valve body, and on Lid is connected by bolt between valve body, and the gasket seal is embedded in the inner chamber of valve body, and gasket seal abuts against lid Bottom, the decompressor is arranged on the side of valve body, and the pressure spring, diaphragm are embedded in the inside of decompressor, And be connected by pressure spring between diaphragm and adjusting knob, the pressure gauge is located at the side of decompressor, and pressure gauge It is connected by pipeline between valve body.
Preferably, the valve disc is rotatable device, and the rotating range of valve disc is 0-90 degree.
Preferably, the inner chamber of the decompressor is provided with back-moving spring, and back-moving spring is arranged on the lower end of diaphragm.
Preferably, corrosion-inhibiting coating is equipped with the outside of the valve disc, valve seat and diaphragm.
Preferably, the diaphragm is for can adjusting means up and down.
Compared with prior art, the beneficial effects of the utility model are:The swing check valve is provided with decompressor, can subtract Impulsive force during little medium back flow to valve disc, makes valve disc more not easy fracture, is provided with adjustable diaphragm, can as needed to being situated between The pressure of matter is adjusted, and not only can prevent medium back flow but also adjustable pressure, and function is more, and the outside of valve disc, valve seat and diaphragm is equal Corrosion-inhibiting coating is provided with, favorable anti-corrosion effect, long service life are cost-effective.
Description of the drawings
Fig. 1 is the utility model structural representation.
