Abstract
The utility model discloses a star-like discharge valve used for pneumatic transmission. The star-like discharge valve comprises a shell. The upper part of the shell is provided with a feed port, while the lower part of the shell is provided with a discharge port. The shell is internally equipped with a rotor impeller. The star-like discharge valve is characterized in that the upper part of the shell is provided with a circular arc-shaped movable pressing plate cooperating with the rotor impeller, and an adjustable pressure spring is arranged on the circular arc-shaped movable pressing plate. By virtue of the cooperative usage of the adjustable pressure spring and the movable pressing plate, the tightness of the movable pressing plate and the rotor impeller can be guaranteed. Therefore, the air tightness of the discharge valve is ensured; the efficiency of a pneumatic transmission system is greatly increased; the production stability is guaranteed; and the wear is effectively decreased. Furthermore, the system stability is improved; the replacement cost of wear parts is lowered; and the service life is prolonged.
Description
Technical field
The utility model relates to the star-like rotary valve that a kind of wear-resisting type that is applied to the conveying of powder material strength is easily changed wear-out part, particularly a kind of star-shaped discharge valve being applied to for strength conveying.
Background technology
The existing star-shaped discharge valve that is applied to strength conveying, all apply traditional star-shaped discharge valve, but under the harder operating mode of material ratio, or material has certain adhering situation, after the ，Dang gap of can cause very soon wearing and tearing between rotor and discharging valve housing acquires a certain degree, the insufficient pressure that causes strength to carry, this structure cannot regulate the intermittence reducing between discharge valve housing and rotor, thereby causes transport efficiency obviously to decline, until cisco unity malfunction.Need so frequent replacing, owing to being integral structure, replacement cost is high, and work is very unstable, greatly reduces the efficiency of production.
Summary of the invention
Technical problem to be solved in the utility model is for the deficiencies in the prior art, provides a kind of reasonable in design, the star-shaped discharge valve of carrying for strength in the gap between energy adjustment housings and rotor.
Technical problem to be solved in the utility model is to realize by following technical scheme, the utility model is a kind of star-shaped discharge valve of carrying for strength, comprise housing, housing top is provided with inlet point, bottom is provided with discharge port, in housing, be provided with rotor wheel, be characterized in: described housing top is set to the circular arc movable pressing board coordinating with rotor wheel, and circular arc movable pressing board is provided with adjustable holddown spring.
Technical problem to be solved in the utility model can also further realize by following technical scheme, and described adjustable holddown spring is provided with two groups, and symmetry is located at the both sides of circular arc movable pressing board.
Technical problem to be solved in the utility model can also further realize by following technical scheme, on the outside face of circular arc movable pressing board inner side and rotor wheel, is coated with respectively coated with wear-resisting alloy.
Technical problem to be solved in the utility model can also further realize by following technical scheme, and coated with wear-resisting alloy is tungsten carbide coating.
Compared with prior art, the utility model is used in conjunction with by adjustable holddown spring and movable pressing board, can guarantee the compactness of movable pressing board and rotor wheel, thereby guarantee the air-tightness of discharge valve, greatly improve the efficiency of air-transport system, guaranteed the stability of producing, and effectively reduce and wear and tear, the further stability of raising system, has reduced the replacement cost of worn parts, improves service life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Referring to accompanying drawing, further describe concrete technical scheme of the present utility model, so that those skilled in the art understands the utility model further, and do not form the restriction to its right.
Embodiment 1, with reference to accompanying drawing 1, a kind of star-shaped discharge valve of carrying for strength, comprise housing, housing top is provided with inlet point 1, and bottom is provided with discharge port 6, in housing, be provided with rotor wheel 5, described housing top is set to the circular arc movable pressing board 3 coordinating with rotor wheel 5, and circular arc movable pressing board 3 is provided with adjustable holddown spring 2, and adjustable holddown spring 2 is fixed on circular arc movable pressing board 3 by support.
Circular arc movable pressing board 3 is compressed by adjustable holddown spring 2, in production, wearing and tearing are continuous processes, when mild wear appears in rotor wheel 5 and 3 of movable pressing boards, by adjustable holddown spring 2, automatically adapt to and compress, thereby assurance air-tightness, causes material can be dumped into from inlet point 1 actv. the discharge port 6 of bottom.
