Abstract
The invention provides a fastening and positioning device arranged between an upper valve shaft and a lower valve shaft of a fully-encapsulated check valve. The fastening and positioning device comprises the upper valve shaft, the lower valve shaft, a positioning clamping plate and a fastening clamping plate. The positioning clamping plate and the fastening clamping plate are provided with downward protruding parts in the radial direction of the upper valve shaft and the lower valve shaft. A positioning clamping groove is formed in the center of the positioning clamping plate. An oblique slope face is arranged on the upper portion of the positioning clamping groove. A cylindrical body matched with the diameter of the upper valve shaft is arranged on the lower portion of the positioning clamping groove. The fastening clamping plate is arranged on the lower side of the positioning clamping plate. A fastening guard plate is arranged on the protruding part of the fastening clamping plate. A buffer valve cushion is arranged in the center of the protruding part of the fastening clamping plate. A ball is arranged at the top of the lower valve shaft. The upper valve shaft is tightly clamped on the inner side of the fastening guard plate through a valve shaft positioning base. Due to the positioning clamping groove and the ball at the top of the lower valve shaft, the production efficiency of the upper valve shaft and the lower valve shaft during assembly can be improved easily and deviation is not prone to occur. Due to the arrangement of the buffer valve cushion, impact on joint of the valve shafts by the vibration between the valve shafts can be effectively reduced, abrasion of encapsulations is reduced, and the service life of the valve is prolonged.
Description
Technical field
The invention belongs to technical field of valve manufacturing, especially relate to the fastening positioning device between lower valve shaft on a kind of full encapsulate safety check.
Background technique
Full encapsulate safety check is used for pipe-line system, and its Main Function prevents medium from flowing backwards, prevents pump and drive motor reversion thereof, and the releasing of container inner medium.The auxiliary system that safety check also can be used for may being raised above main system pressure to pressure wherein provides on the pipeline of supply.The upper valve shaft of the safety check of full encapsulate, the fastening guarantee being safety check and normally working of lower valve shaft docking, in use due to vibrations and wearing and tearing to cause upper valve shaft and lower valve shaft to departing from, and then there is the problems such as the unstable and valve shaft skew of closing operation.Therefore, prior art existing defects, requires further improvement and perfect, carries out further reinforce stabilization to the connection of valve shaft.
Summary of the invention
The problem to be solved in the present invention solves to connect between valve shaft easily to loosen, depart from the fluctuation of service caused, and is particularly suitable for the fastening location use of lower valve shaft on full encapsulate safety check.
For solving the problems of the technologies described above, the technical solution used in the present invention is: the fastening positioning device on a kind of full encapsulate safety check between lower valve shaft, comprise valve shaft, lower valve shaft, locating clamp plate and binding clip, described locating clamp plate and binding clip are at upper valve shaft, lower valve shaft radial direction is provided with downward lug boss, wherein, described locating clamp plate center is provided with locating groove, described locating groove top is provided with face of slope, bottom is the cylindrical body with upper valve shaft diameter matches, described binding clip is arranged on the downside of locating clamp plate, described binding clip lug boss is provided with fastening backplate, the lug boss center of described binding clip is provided with buffering valve pad, the top of described lower valve shaft is provided with ball, described upper valve shaft is clamped on inside fastening backplate by valve shaft positioning seat.
Further, the cylindrical inner surface of described locating groove bottom is provided with frosted layer.
Further, on described locating clamp plate and binding clip surrounding and check valve body body.
Further, described buffering valve pad is arranged on the lug boss central position of binding clip, and the upside of described buffering valve pad is locating clamp plate, and the bottom of described buffer memory valve pad is connected with the upper surface of valve shaft positioning seat.
The advantage that the present invention has and good effect are: by the ball at the top of locating groove and lower valve shaft, enhance productivity, and not easily depart from when being convenient to lower valve shaft assembling; The setting of buffering valve pad limitedly can alleviate the impact shaking between valve shaft and connect valve shaft, alleviates the wearing and tearing to encapsulate, increases the working life of valve.
