Working procedure below in conjunction with this safety check further specifies the utility model:
Opening process:
Water pump and drive motor thereof are started working; This moment valve plate 2 on the seal face 20 that closely abuts in main valve body 1 under the effect of himself gravity to realize sealing; This moment since the seal face 20 residing planes of main valve body 1 with respect to the θ angle that tilted of the vertical guide perpendicular to the media flow direction; The axis of valve rod 12 is constituting the second angle γ less than 90 ° perpendicular to MEDIA FLOW between projection on the vertical guide on the direction and vertical line simultaneously; Therefore valve plate 2 also receives the support force from main valve body 1 except the gravity that receives self; When water or other media flow during to valve plate 2 places; The self gravitation of the thrust of water or other media, valve plate 2 and main valve body 1 support force three acting in conjunction are on valve plate; And the axis horizontal drift angle γ of inclination angle theta through main valve body 1 and valve rod 12 obtains a value of making a concerted effort that acts on the valve plate 2; This value of making a concerted effort makes valve plate 2 be opened; When valve plate 2 is opened to 70～80 when spending, the relative balance state of making a concerted effort to be in that the thrust of water or other media, valve plate 2 self gravitations and main valve body 1 support force produce, and be in relative static conditions after making valve plate 2 be opened; When valve plate 2 unlatchings are spent above 80, valve plate 2 contacts with auxiliary valve body 17 to carry out spacing to valve plate 2.Accomplished the opening process of this safety check this moment; And make valve plate 2 reach the complete opening state from buttoned-up status, in this opening process, this side opens the energy-conservation buffer valve of formula owing to unique features on the structure; Make that resistance to water-flow is little when opening; Loss of head is little, and the big and less energy consumption of opening angle has energy-efficient advantage.
Close closed procedure:
When water pump and drive motor thereof quit work, because the flow and the flow velocity of water or other media constantly reduce, the water or the thrust of other media that therefore act on the valve plate 2 also constantly reduced.And the generation of the support force of the self gravitation of valve plate 2 and main valve body 1 is constant with joint efforts; Therefore valve plate 2 will carry out near the rotation of substantially horizontal side direction around the valve rod 12 that is fixed on the main valve body 1, because the existence of the axis horizontal drift angle γ of the inclination angle theta of main valve body 1 and valve rod 12, thereby the value of making a concerted effort that valve plate 2 is received is less relatively; The value of making a concerted effort that this is less is closed valve plate 2 lentamente; When valve plate 2 will be closed fully, the Slow Close axle 3 on the valve plate 2 touched gland 6, and the termination of Slow Close axle 3 is pressed against on the gland 6; And the direction pressure spring 7 that limits along guide sleeve 5; Spring 7 is fixed on the inside grooves of Slow Close seat 9, and after spring 7 compressions put in place, the seal face 20 of valve plate 2 and main valve body 1 fitted and makes valve close fully.Meanwhile; Water in the groove is got into the inner chamber of spring 7 by the through hole on gland 6 closed ends; The water that gets into the inner chamber of spring 7 is expelled back into main valve body 1 through plug screw 8 again, and the adjustable size of the weep hole on the plug screw 8, so that the hydraulic pressure in the inner chamber of spring 7 is regulated.When the inner chamber of spring 7 does not have water, also promptly reach no hydraulic pressure Slow Close state, only depend on spring 7 to carry out Slow Close this moment.When the seal face 20 of valve plate 2 and main valve body 1 fits; Because the outside integral coating of valve plate 2 has the nitrile butadiene rubber layer, therefore good seal performance not only, damping is wear-resisting; Have shock-resistant, anti-aging and corrosion resistant function, but also have advantages such as long service life and stable working be reliable.This process has been accomplished the pass closed procedure that side opens the energy-conservation safety check of formula, makes the valve plate 2 reach buttoned-up status from the complete opening state.Do not have bump when closing valve, good seal performance and damping are wear-resisting, and body cavity is streamlined simultaneously, and runner is wide, has eliminated water hammer.
