Described support preferably is made of two supporting plates that bilateral symmetry distributes.
Described flap can be provided with the rocking bar hinged with described support.
The articulated manner of described support and described rocking bar is can be provided with the pin-and-hole that cooperatively interacts on described support and the rocking bar, and described support can be connected by the bearing pin with described pin-and-hole cooperation with rocking bar.
When two supporting plates that distributed by bilateral symmetry when described support constituted, the pin-and-hole on the described support vertically penetrated described supporting plate.
Described rocking bar preferably is removably mounted on the described flap.
The lower end that the Placement of described support and described valve seat is preferably described support is welded on the upper surface at described valve seat top.
The side that is preferably described support is welded on the inwall of described valve body.
The seal face of described valve seat is preferably the inclined-plane of inclination, and true dip direction is from up to down towards the direction of the outlet of described valve body.
The Placement of described valve seat and described valve body can be welding, the seal ring that is used to seal can be provided with on the sealing surface of described valve seat or on the sealing surface of described flap, perhaps the seal ring that cooperatively interacts can be respectively equipped with on the sealing surface of the sealing surface of described valve seat and described flap.
The utility model beneficial effect compared with prior art is: the utility model will support described flap and do and revolve the support of start doing and be fixedly installed on the upper surface of described valve seat, and the cooperation rocking bar hinged with it, can make the motion of described flap be the state of opening that revolves, fixed platform need be set again in order to support described flap in the valve pocket of described valve body, reduced the difficulty of processing of valve body, reduced the locating element in the valve pocket, installing space is reduced greatly, also make described flap obtain bigger open degree simultaneously; The width of the part that described rocking bar and described support are hinged be arranged to and two described supports between width corresponding, can guarantee that described flap can not swing in revolving the process that opens or close, guarantee the sealing effect when described flap is closed; The side of described support and the welding of the inwall of described valve body make the fixing more reliable of described support; The seal face of described valve seat is made as the inclined-plane of inclination, makes that the sealing surface of described valve seat is met the moving direction to the sealing surface of described flap when the reverse flow valve of medium, forms sealing at an easy rate, has guaranteed the sealing effect when flap is closed further.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the assembling schematic representation of the utility model valve seat and support.
Embodiment
In order better to explain the utility model, so that better understand the utility model, the utility model will be further described below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1 and Fig. 2, the utility model provides a kind of Swing check valve, comprise valve body 1, be arranged at the valve seat 2 in the described valve body and constitute the flap 3 of sealing pair with described valve seat, described valve body internal fixation be provided be used to support described flap bottom-up do to revolve start shipment moving support 4.Described support is preferably disposed on the top of described valve seat, to guarantee the opening direction of described flap, the lower end that the means of fixation of described support is preferably described support is welded on the upper surface at described valve seat top, the mode of welding is preferably the curved welding of cylindrical upper surface at described support and described valve seat top, so that fixing more reliable, select other suitable Placement for the consideration of join strength, manufacture difficulty and cost in also can be according to actual needs between described support and the valve seat.Described support is fixedly set on the upper surface at described valve seat top, can make the motion of described flap be the state of opening that revolves, need in the valve pocket of described valve body, not be provided with again in order to support the fixed platform of described flap motion, reduced the difficulty of processing of valve body, reduced the locating element in the valve pocket, installing space is reduced greatly, also make described flap obtain bigger open degree simultaneously.The side of described support can be welded on the inwall of described valve body, makes the fixing more reliable of described support.
