Abstract
The utility model relates to a trussed type telescopic butterfly valve, comprising a valve body (3), sealing rings (5) which are arranged on trussed type valve plates (8) inside a flow channel of a valve body and are arranged inside sealing ring grooves processed on the periphery of the trussed type valve plates (8) by press plates (6), and an expansion joint (10) which is sheathed inside a prolonged section of the flow channel of the valve body. The utility model is characterized in that a valve seat (4) made of corrosion-proof metal material is inlaid on the ring surface of the flow channel of the valve body, which is matched with the sealing rings (5); the trussed type valve plates are respectively combined with an upper and a lower half shafts (1) and (9) through connecting pieces (7); the expansion joint (10) is combined with the valve body by the mode that a gland (2) tightly presses sealing material (11).
Description
The utility model relates to a kind of valve, relates to the flexible butterfly valve of a kind of truss type specifically.
The flexible butterfly valve of formula is widely used a kind of valve, and also expose the some shortcomings part through for many years use: 1. because its valve shaft is an axis structure, it is big to take Flow area, causes the increase of medium flow resistance; 2. because it is fixedly mounted on the valve seat that seals in the valve flowing channel mostly is rubber material and is made, easily leak in use for some time,, directly have influence on the working life of whole valve in case leak then difficult reparation; 3. because the sealing between between its slip joint and valve flowing channel junction plane is to adopt hydraulic type sealing structure form, use a period of time after, the corrosion because of fed sheet of a media often causes sealing the position leakage, and easy-maintaining not.
The purpose of this utility model provides a kind of structure more reasonable with regard to being to overcome above-mentioned deficiency of the prior art, and long service life is for ease of maintenaince with the flexible butterfly valve of the truss type of changing parts.
The purpose of this utility model can adopt following measure to realize:
The flexible butterfly valve of the purpose of this utility model truss type comprises valve body, be installed in the truss type valve plate in the valve flowing channel and be installed in seal ring in the closure gasket groove that processes on the truss type valve plate periphery by pressing plate, and be sleeved on the interior slip joint of valve flowing channel prolonged section, on the valve flowing channel anchor ring that matches with seal ring, be installed with the valve seat that adopts the corrosion resistant metallic material to be made; Described truss type valve plate combines with two semiaxis up and down respectively by link; Slip joint compresses sealing material by gland mode combines with valve body.
The utility model not only has greatly compared to existing technology can increase actual Flow area, reduces the advantage of flow resistance, and has difficult the leakage, easy to maintenance, the advantage of long service life.
The drawing of accompanying drawing is described as follows:
Fig. 1 is a plan view of the present utility model.
Fig. 2 is the A-A sectional view of Fig. 1.
The utility model is done with detailed description below with reference to embodiment's (accompanying drawing):
As shown in the figure, the flexible butterfly valve of the purpose of this utility model truss type comprises valve body (3), be installed in the truss type valve plate (8) in the valve flowing channel and be installed in the interior seal ring (5) of closure gasket groove that processes on truss type valve plate (8) periphery by pressing plate (6), and be sleeved on slip joint (10) in the valve flowing channel prolonged section, with valve flowing channel anchor ring that seal ring (5) matches on be installed with the metal seat valve (4) that adopts stainless steel material to be made, the adjustment of the magnitude of interference between metal seat valve (4) and the seal ring (5) is that the degree of tightness by adjustment pressing plate (6) realizes; Described truss type valve plate (8) combines with two semiaxis (1) (9) up and down respectively by taper connection pin (7); Slip joint (10) combines with valve body by the mode that gland (2) compresses stuffing box packing (11).
Claims (1)
1, the flexible butterfly valve of a kind of truss type, seal ring (5) in the closure gasket groove that processes on truss type valve plate (8) periphery, and be sleeved on slip joint (10) in the valve flowing channel prolonged section, it is characterized in that: with valve flowing channel anchor ring that seal ring (5) matches on be installed with the valve seat (4) that adopts the corrosion resistant metallic material to be made; Described truss type valve plate (8) combines with two semiaxis (1) (9) up and down respectively by link (7); Slip joint (10) combines with valve body by the mode that gland (2) compresses sealing material (11).
