Abstract
The utility model discloses a bidirectional sealed parallel type combined gate plate with a double gate plate gate valve. The combined gate plate comprises a clamp ring (1) and a valve clack group (3), wherein the clamp ring (1) is provided with an assembling hole; the valve clack group (3) of which the upper end is arranged in the assembling hole is provided with an elastic component (2); and an adjusting device for locking the valve clack group (3) is arranged on the combined gate plate. The bidirectional sealed parallel type combined gate plate with the double gate plate gate valve can adjust and control the valve clack group even when the elastic component arranged in the valve clack group is in a free state, so that the valve clack group is effectively prevented from falling off the assembling hole of the clamp ring, the sealing surface of the valve clack group is perfectly attached to the sealing surface of a valve seat and assembling difficulty is reduced; and the combined gate plate has a simple structure and is convenient and applicable.
Description
Technical field
The utility model belongs to valve technology field, is specifically related to a kind of flashboard of two way sealed double disk parallel gate valve.
Background technique
Tradition two way sealed double disk parallel gate valve mainly is made up of valve seat and flashboard, this flashboard comprises the flap group that is assemblied in this valve seat, this flap group comprises a pair of flap, be respectively import flap and outlet flap, the upper end of this import flap and outlet flap all is assemblied in the pilot hole of clamping ring, and be provided with spring between two flaps in order to distance is between the two adjusted, thereby the mobile of medium controlled.For the flashboard of this traditional two way sealed double disk parallel gate valve, its assembly process extremely bothers, it must adopt special assembly tool earlier above-mentioned spring to be carried out prestressing, and then flap is assembled in the valve seat, this assembly tool need disassemble after assembling the flap group, therefore, when spring is in free state, can't adjust the distance between import flap and the outlet flap, thereby easily cause whole flap group accident from the pilot hole of clamping ring to come off and cause damage, its assembling difficulty is bigger.
The model utility content
At above-mentioned deficiency, the utility model provides a kind of can prevent effectively that flap group accident from the pilot hole of clamping ring from coming off and the combined type flashboard of the very simple two way sealed double disk parallel gate valve of assembly process.
The utility model is to realize by such technological scheme:
A kind of combined type flashboard of two way sealed double disk parallel gate valve, comprise that the clamping ring that has pilot hole and upper end are arranged in the described pilot hole and are fitted with the flap group of elastic member, this combined type flashboard is provided with the controlling device that described flap group is locked.
Described controlling device comprises bolt and the nut that the restraining groove, the lower end that are arranged on the described flap group cylindrical place back-up ring in the described restraining groove, pass across the upper end of described back-up ring and clamping ring and by this back-up ring described flap group is clamped simultaneously, promptly regulate described nut, make described back-up ring with respect to described flap prescription to the motion to lock this flap group, prevent that its accident from the pilot hole of described clamping ring from coming off; Simultaneously, described back-up ring and restraining groove mating reaction have limited the axial motion of described flap group.
It is good that described restraining groove adopts circular groove, and the restraining groove of other shapes can certainly be set according to actual conditions.
In order more accurately described flap group to be locked adjusting, described nut adopts slotted nut, and described bolt is provided with the cotter pin that cooperates with described nut, and is spacing in order to described nut is carried out, and prevents to relatively rotate between itself and the described bolt.
Owing to adopted said structure, the beneficial effects of the utility model are as follows:
In sum, the combined type flashboard of the two way sealed double disk parallel gate valve that the utility model provides is owing to set up the controlling device that the flap group is locked, this controlling device comprises the restraining groove that is arranged on the flap group, back-up ring and the bolt and the nut of the flap group being locked by back-up ring, therefore, even when being fitted in elastic member in the flap group and being in free state, also can regulate control to the flap group, thereby prevented that effectively the flap group from coming off from the pilot hole of clamping ring, also guaranteed the perfection applying between flap group sealing surface and the sealing surface of seat, reduced the assembling difficulty of whole flashboard, it is simple in structure, convenient being suitable for.
Description of drawings
Fig. 1 is the structural representation of the combined type flashboard of two way sealed double disk parallel gate valve among the utility model embodiment, and the arrow among the figure is represented the flow direction of medium.
Embodiment
In order to be expressly understood the purpose of this utility model, technological scheme and beneficial effect more, below in conjunction with accompanying drawing the utility model is described further, but protection domain of the present utility model is not limited in following examples.
As shown in Figure 1, a kind of combined type flashboard of two way sealed double disk parallel gate valve, comprise that the clamping ring 1 that has pilot hole and upper end are arranged in the described pilot hole and are fitted with the flap group 3 of elastic member 2, this combined type flashboard is provided with the controlling device that described flap group 3 is locked; Described controlling device comprises that the restraining groove 4, the lower end that are arranged on described flap group 3 cylindricals place back-up ring 5, the upper end that passes across described back-up ring 5 and clamping ring 1 in the described restraining groove 4 and bolt 6, the nut 7 of locking by 5 pairs of described flap groups 3 of this back-up ring; Described restraining groove 4 is a circular groove; Described nut 7 is a slotted nut, and described bolt 6 is provided with the cotter pin 8 that cooperates with described nut 7, relatively rotates with respect to described bolt 6 to prevent described nut 7; Before valve seat 9 that described flap group 3 is packed into, turn described nut 7 earlier, it is locked described flap group 3 by described back-up ring 5, thereby with described elastic member 2 prestressing, again described flap group 3 is packed in the described valve seat 9, this compression process can be adjusted at the ultimate range between described flap group 3 inner sealing surfaces than the big 2～3mm of distance between described valve seat 9 inner sealing surfaces, this has not only guaranteed the perfection applying between the sealing surface in sealing surface and the described valve seat 9 in the described flap group 3, prevented effectively that also described flap group 3 accident from the pilot hole of described clamping ring 1 from coming off, it is simple in structure, is easy to assembling.
