How to reduce slot butterfly valve body blank weight, realize slot butterfly valve lightweight, reduce slot butterfly valve material consumption and manufacturing cost, how to improve slot butterfly valve body latus rectum machining efficiency is the problem that needs to solve.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the technical problem that will solve is: a groove butterfly valve is provided. The groove butterfly valve can reduce the weight of the blank of the valve body of the groove butterfly valve, realize the light weight of the groove butterfly valve, reduce the material consumption and the manufacturing cost of the groove butterfly valve, and improve the processing efficiency of the drift diameter of the valve body of the groove butterfly valve.
The utility model provides a technical scheme of above-mentioned technical problem is: the utility model provides a groove butterfly valve, includes slot butterfly valve body, slot butterfly valve butterfly plate, have on the slot butterfly valve body inner wall with the sealed face matched with latus rectum of slot butterfly valve butterfly plate, the upper and lower both ends of slot butterfly valve butterfly plate set up the similar half olive shape structure in part in shaft hole, lower shaft hole, still include the screw hole that lies in the installation water pressure detection device that sets up respectively on slot butterfly valve clack both sides position on the slot butterfly valve body wall, characterized by: the drift diameter arranged on the inner wall of the groove butterfly valve body is provided with two wider parts and two narrower parts which are sequentially connected into a whole, the sizes of the two wider parts of the drift diameter arranged on the inner wall of the groove butterfly valve body are respectively corresponding to the partial maximum width sizes of half olive-shaped structures similar to the upper end and the lower end of the groove butterfly valve butterfly plate, and the sizes of the two wider parts of the drift diameter arranged on the inner wall of the groove butterfly valve body are respectively consistent with the partial maximum width sizes of half olive-shaped structures similar to the upper end and the lower end of the groove butterfly valve butterfly plate; the size of the two narrower parts of the drift diameter arranged on the inner wall of the valve body of the groove butterfly valve is respectively corresponding to the width size of the sealing surface of the butterfly plate of the groove butterfly valve, and the size of the two narrower parts of the drift diameter arranged on the inner wall of the valve body of the groove butterfly valve is respectively consistent with the width size of the sealing surface of the butterfly plate of the groove butterfly valve; the threaded holes for installing the water pressure detection devices, which are respectively arranged on the two sides of the valve clack of the groove butterfly valve on the valve body wall of the groove butterfly valve, are respectively close to the two sides of a narrow part of the drift diameter arranged on the inner wall of the valve body of the groove butterfly valve.
The utility model has the advantages that: because the drift diameter arranged on the inner wall of the groove butterfly valve body of the utility model is provided with two wider parts and two narrower parts which are connected into a whole in sequence, the sizes of the two wider parts of the drift diameter arranged on the inner wall of the groove butterfly valve body are respectively corresponding to the maximum width sizes of the parts of the upper end and the lower end of the butterfly plate of the groove butterfly valve, which are provided with an upper shaft hole and a lower shaft hole which are similar to half olive-shaped structures; the sizes of two narrow parts of the drift diameter arranged on the inner wall of the valve body of the groove butterfly valve correspond to the width size of the sealing surface of the butterfly plate of the groove butterfly valve respectively; the threaded holes of the installation water pressure detection devices, which are respectively arranged on the two sides of the valve clack of the groove butterfly valve on the valve body wall of the groove butterfly valve, are respectively close to the two sides of a narrow part of the drift diameter arranged on the inner wall of the valve body of the groove butterfly valve. Because two narrower part sizes of latus rectum that set up on the slot butterfly valve body inner wall respectively should the sealed face width size of slot butterfly valve butterfly plate relatively, the screw hole that lies in installation water pressure detection device that sets up respectively on slot butterfly valve clack both sides position on the slot butterfly valve body wall still is close to the both sides of the narrower part of latus rectum that set up on this slot butterfly valve body inner wall respectively, for current slot butterfly valve body, the utility model discloses the corresponding slot butterfly valve that has shortened slot butterfly valve body structure width size, has shortened the latus rectum width that sets up on the slot butterfly valve body inner wall, has realized that slot butterfly valve body blank reduces heavily, has realized this slot butterfly valve lightweight, has reduced this slot butterfly valve material consumption and manufacturing cost, has improved this slot butterfly valve body latus rectum machining efficiency. Take the groove butterfly valve of DN300 as an example: the weight of the existing groove butterfly valve is 22.77 kg, the structural width of the groove butterfly valve body is 220 mm, and the drift diameter width arranged on the inner wall of the groove butterfly valve body is 55.6 mm; the weight of the groove butterfly valve is 19.19 kg, which is 15.7 percent of the weight of the groove butterfly valve; the width of the valve body structure of the groove butterfly valve is 194 mm, and is reduced by 26 mm compared with the width of the valve body structure of the existing groove butterfly valve; the latus rectum width that sets up on the slot butterfly valve body inner wall is 42 millimeters, reduces 13.6 millimeters for the latus rectum width that sets up on the current slot butterfly valve body inner wall.
