Background

The so-called swing check valve is a check valve or a check valve, which is used for preventing media in a pipeline from flowing backwards, and an opening and closing part is automatically opened or closed by the force generated by the flowing of the media to prevent the media from flowing backwards, so that the valve is called a check valve.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a have and prevent that valve clack from floating indefinite swing check valve to the prior art check valve of solution is in not stopping swing and vibration state in normal operating because the inside valve clack of valve body is wafted in aqueous, leads to the valve clack to be difficult to stabilize in full open position when the medium circulates, forces this check valve flow resistance and friction increase and the problem of easily damaging.

In order to achieve the above purpose, the present invention is realized by the following technical solutions: a swing check valve with function of preventing valve clack from floating variably, the structure comprising: check valve body, check valve body both sides all are equipped with flange, check valve body still includes controller, electro-magnet, connection cable, rivers sensor, valve clack, the sealed lantern ring, the controller is connected with the electro-magnet electricity, rivers sensor is connected with the controller through connection cable, the lower extreme of electro-magnet runs through in the sealed lantern ring, one side of controller is equipped with the sealed lantern ring that is used for isolated valve clack.

Preferably, the sealing device further comprises two limiting screws, a sealing flange and a connecting column, wherein the two sealing flanges are arranged at the lower end of the limiting screws, and the upper end of the connecting column is connected with the lower end of the sealing flange.

Preferably, the water inlet device further comprises a connecting rotating shaft, a water inlet, a rocker arm and a water outlet, wherein one side of the rocker arm is connected with the connecting rotating shaft, and the water inlet is arranged on the left side of the water outlet.

Preferably, the lower end of the rocker arm is in transmission connection with a valve flap, and one side of the valve flap is attached to the water inlet.

The utility model discloses owing to adopted above technical scheme, have apparent technological effect: when a medium flows into the water inlet, the water flow sensor senses that the medium flows through, the water flow sensor conducts sensed data to the controller under the action of the wiring cable, the controller drives the electromagnet to be electrified to have magnetic force, the rocker arm is upwards attracted around the connecting rotating shaft, the valve clack is upwards adsorbed by the electromagnet in a maximum opening mode, the check valve adsorbs the valve clack through the water flow sensor, the valve clack can be stably at a full-open position when the medium flows in the water inlet, and the check valve is prevented from being influenced by continuous swinging of the valve clack to increase the medium flow resistance.

Fig. 1 is a schematic structural diagram of a swing check valve with a function of preventing a valve clack from floating variably.

Fig. 2 is the structure diagram of the check valve body of the present invention.

The names of the parts indicated by the numerical references in the drawings are as follows: the water-saving valve comprises a limiting screw-1, a sealing flange-2, a connecting column-3, a connecting flange-4, a check valve body-5, a controller-501, an electromagnet-502, a connecting cable-503, a connecting rotating shaft-504, a water flow sensor-505, a water inlet-506, a valve clack-507, a rocker-508, a water outlet-509 and a sealing lantern ring-510.

Detailed Description

In order to make the technical means, the creation features, the achievement purposes and the effects of the utility model easy to understand, the utility model is further described below by combining with the specific embodiments.

Referring to fig. 1-2, the present invention provides a swing check valve with a floating and unsteady valve flap, which comprises: the check valve comprises a check valve body 5, wherein connecting flanges 4 are arranged on two sides of the check valve body 5, the check valve body 5 further comprises a controller 501, an electromagnet 502, a wiring cable 503, a water flow sensor 505, a valve clack 507 and a sealing lantern ring 510, the controller 501 is electrically connected with the electromagnet 502, the water flow sensor 505 is connected with the controller 501 through the wiring cable 503, the lower end of the electromagnet 502 penetrates through the sealing lantern ring 510, one side of the controller 501 is provided with the sealing lantern ring 510 used for isolating the valve clack 507, the check valve further comprises a limit screw 1, a sealing flange 2 and a connecting column 3, the sealing flange 2 is provided with two parts and is arranged at the lower end of the limit screw 1, the upper end of the connecting column 3 is connected with the lower end of the sealing flange 2, the check valve further comprises a connecting rotating shaft 504, a water inlet 506, a rocker arm, the water inlet 506 is arranged at the left side of the water outlet 509, the lower end of the rocker arm 508 is in transmission connection with a valve flap 507, and one side of the valve flap 507 is attached to the water inlet 506.
