Abstract
The utility model relates to the field of valve lifting of a diaphragm pump, especially relates to a novel special tool for valve seat lifting of a diaphragm pump, which can increase the success rate of valve lifting, and is not easy to be disconnected when being fastened, enhance stability and security, and improve maintenance efficiency. The utility model provides a novel special tool for valve seat lifting of a diaphragm pump which can guarantee power required for valve lifting, increase success rate of valve lifting, enhance stability and security, save work time and improve work efficiency. The novel special tool for valve seat lifting comprises a screw and a valve-lifting oil cylinder connected to the screw. The screw is provided with a fastening nut, and the valve-lifting oil cylinder is connected to a hand-operated hydraulic cylinder through an inlet pipe of the oil cylinder. The hand-operated hydraulic cylinder is connected to a hand-operated hydraulic pump through a high-pressure oil pipe. The valve-lifting oil cylinder is provided with a drain valve. The novel special tool for valve seat lifting of a diaphragm pump is advantageous in that mounting and dismounting of the novel special tool are both conducted by a double-beam crane in a hoisting manner, and pressure is generated by using a hand-operated hydraulic pump; the novel special tool is connected to a high-pressure oil pipe; operation is convenient and fast; valve-lifting time is saved by three times compared with that of the prior art, and maintenance efficiency is greatly improved.
Description
Technical field
The utility model relates to membrane pump and opens the valve field, and particularly a kind of increase opens the success rate of valve seat, difficult drop-off when fastening, the membrane pump that strengthened stability and security, raising service work efficient open valve new exclusive instrument.
Background technology
At present; The pulling capacity that opens valve is that threaded screw rod directly produces with jack, and it is abundant to guarantee to open the required power of valve, and opening valve is to get into the expansion that is produced in the two seals circle of valve seat own through hydraulic oil to realize; The easy damaged leakage of oil of valve seat insert when opening valve; Cause valve seat to be difficult to open out, the inconvenient time of use is longer, can not increase work efficiency.
Summary of the invention
The purpose of the utility model is to overcome the deficiency that exists in the prior art and provides a kind of assurance to open the valve required drive, increases the membrane pump open valve success rate, enhanced stability and security, saving working time and to increase work efficiency and open valve new exclusive instrument.
The purpose of the utility model is achieved in that a kind of membrane pump opens valve new exclusive instrument and comprises: screw rod, be connected with screw rod open the valve oil cylinder; Screw rod is provided with clamp nut; It is characterized in that: the described valve oil cylinder that opens is connected with the hand-hydraulic cylinder through the oil cylinder oil inlet pipe; Described hand-hydraulic cylinder is connected with hydraulic hand-pump through high-pressure oil pipe, and described opening also is provided with drain valve on the valve oil cylinder.
One end of said screw rod has valve head and beats the rope hole, and the other end is provided with activity and opens valve head.
Said clamp nut is provided with the nut anchorage bar.
Said opening is fixed with the oil cylinder stroke fastening bolt on the valve oil cylinder.
Said hydraulic hand-pump is provided with oil pump tank filler sleeve and oil pump relief valve, and said oil pump relief valve is connected with the hydraulic pump depression bar.
The utility model produces pulling capacity through cylinder design, replaces original threaded screw rod directly to open the pulling capacity that valve produces with jack, and the pulling capacity of hydraulic pressure generation in use is very huge, is equivalent to about 250 tons top power, has guaranteed to open the required power of valve; Also open valve head and directly act on the valve seat bottom through activity; Replace getting into the expansion that is produced in the two seals circle of valve seat own through hydraulic oil originally; Thoroughly solved the damaged leakage of oil of valve seat insert when opening valve originally, a difficult problem that causes valve seat to be difficult to open out has increased the success rate that opens valve seat; The hydraulic cylinder of the utility model be directly installed in use clack box above, activity is opened valve head and is fallen valve seat bottom and hang the jail, difficult drop-off when fastening has strengthened stability and has opened valve process safe property; The utility model is in use laid, is dismantled by two fine strain of millet driving lifting cooperations in the factory building; Supporting use hydraulic hand-pump produces pressure; There is high-pressure oil pipe to connect; Convenient to operation, saved three times in time than the old-fashioned valve instrument that opens that use early stage, improved the operating efficiency of maintenance greatly.
