Valve deck is locked on valve body by the first bolt and the second bolt, and the first bolt and the second bolt are oppositely arranged, the first nut and
One bolt coordinates, and the second nut and the second bolt coordinate, so that valve deck is fixed on valve body, and when the check-valves works
Dislocation is not easy to move.Gasket is equipped between valve deck and valve body, to when the check-valves works, prevent valve deck bounce relaxation.
Description of the drawings
Fig. 1 is the structural schematic diagram of the Slow Close Valve of the utility model first embodiment.
Specific implementation mode
It is new to this practicality below in conjunction with attached drawing to keep the purpose of this utility model, technical solution and advantage clearer
Each embodiment of type is explained in detail.However, it will be understood by those skilled in the art that each in the utility model
In embodiment, in order to make the reader understand this application better, many technical details are proposed.But even if without these skills
Art details and various changes and modifications based on the following respective embodiments can also realize that each claim of the application is required and protect
The technical solution of shield.
The first embodiment of the utility model is related to a kind of Slow Close Valve, as shown in Figure 1, including valve body 1, valve deck 4,
Gasket 3, locking member, valve seat 18, flap, counterweight component and oil hydraulic cylinder 2.It is equipped with inner cavity 17 in valve body 1, valve body 1 includes and inner cavity
The liquid outlet 16 that 17 inlets 15 communicated and inlet 15 are oppositely arranged.Valve deck 4 is arranged on the top of valve body 1.Gasket 3 is arranged
Between valve deck 4 and valve body 1.Locking member includes the first bolt 7 and the first bolt 7 for being connected to valve deck 4 on valve body 1
Match by the first nut 8 that valve deck 4 is locked on valve body 1, the second bolt 10 for being connected to valve deck 4 on valve body 1, with
Second bolt 10 matches the second nut 11 being locked at valve deck 4 on valve body 1, and the first bolt 7 and the second bolt 10 are opposite
Setting, the first nut 8 and the second nut 11 are oppositely arranged.Valve seat 18 is arranged in inner cavity 17.Flap is arranged in inner cavity 17, uses
In blocking or opening inlet 15, include the flap ontology 5 hinged with valve seat 18, setting in flap ontology 5 towards inlet 15
The rubber pad 13 of side, the fitting of rubber pad 13 is sticked on flap ontology 5, then rubber pad 13 is locked at flap sheet by bolt 14
On body 5, while making the fastening installation of rubber pad 13, changeing for rubber pad 13 is also convenient in the later stage.Counterweight component is used for
Auxiliary flap blocks inlet 15, includes the connecting rod 12 being hinged with flap ontology 5, the weight ontology 6 being arranged on connecting rod 12.
The setting of oil hydraulic cylinder 2 is being used on valve body 1 when flap is moved towards inlet 15, accepts flap.Meanwhile in the side table of valve body 1
The lower section in face, valve deck 4 is equipped with nameplate 9, for marking the check-valves indices, when installing valve deck 4, can be immediately seen the inscription
The position of board 9, setting is more eye-catching, and is not take up other positions, and the side surface of valve body 1 is made to have extra space that other east are arranged
