Background technique
Known: gate valve mainly comprises valve body, valve gap, gland nut, flashboard, valve rod and unlatching handwheel, sealing on its valve rod is all adopt tetrafluoro filler and compressed and made valve stem seal by gland nut, because easily causing that gland nut is loosening, the frequent Push And Release of valve rod cause medium to leak, sealing effect is poor, valve rod is to pass from valve gap lower end surface when mounted in addition, lock and fix by set screw nut again, again handwheel is arranged on to the end of valve rod, this installation is cumbersome, time-consuming, effort, do not there is again anti-theft feature, manufacturing efficiency also declines thereupon simultaneously.The simultaneously existing rod type gate valve of taking out " is taken out rod type gate valve " as disclosed the one that Chinese Patent Application No. is 02239528.8 on June 23rd, 2002, comprise valve body, valve gap, gland nut, valve plate, valve rod and handwheel, structural design can be extracted valve rod out, in the time of Open valve, gland nut contacts with the design direct metal of valve gap, increase the keying torsion of valve rod, make valve opening effort, this design also has irrational place exactly in the time valve rod being extracted out after valve closing, because pipe interior self exists larger hydraulic pressure, also have when pipeline runs into larger water hammer and produce vibrations, under the assistance that there is no external force, easily cause that the flashboard of cutting out occurs loosening, to cause that serious leakage occurs pipeline medium, this is abnormally dangerous, the existing analogue that occurs at present, make the easy failure loss of building larger, and waste water source, some special industries is carried poisonous and harmful substance by pipeline, the leakage of gate valve medium also can endanger environment and people's physical and mental health.
Summary of the invention
For the problems referred to above; the utility model proposes a kind of simple in structure, easy for installation, can make flashboard sealing firmly, long service life; open and close that moment is little, valve stem seal performance is good and can extract out opening handwheel and valve rod valve closing is complete simultaneously, thering is in addition the modified model pumping rod gate valve with anti-theft protection function.
For solving this technical problem, the utility model is taked following scheme: modified model pumping rod gate valve, comprise valve body, valve gap, flashboard, valve rod and unlatching handwheel, on described valve body, part is provided with water intake and water outlet vertically, described flashboard is located between the interior water intake of valve body and water outlet, between described valve gap and valve body, be provided with gasket seal, described valve rod one end is connected with flashboard through valve gap, described valve gap upper end is provided with between clamping nut itself and valve gap and adopts and be threaded, described unlatching handwheel is located on the free end of valve rod, described valve body below is provided with positioning hole, in described positioning hole, be provided with rotating piston, described flashboard below is provided with and rotating piston connecting thread, between described clamping nut and valve gap, be provided with Tetrafluoro spacer.
Further improved: in described valve rod central slot, to be also provided with two O RunddichtringOs.
Further improved: between described rotating piston and valve body, be also provided with O RunddichtringO, described rotating piston and valve body are also provided with fixed card ring.
By adopting aforementioned techniques scheme, the beneficial effects of the utility model are: this novel improved type pumping rod gate valve, described valve body below is provided with positioning hole, in described positioning hole, be provided with rotating piston, described flashboard below is provided with and rotating piston connecting thread, this simplicity of design is reasonable, in the time of valve closing, and after valve rod is extracted out, can conveniently lock flashboard by rotating piston, make flashboard produce downward pulling force and increase the sealability between flashboard and valve body, make flashboard not occurred by pipeline hydraulic pressure shock effect flashboard loosening, under the state without bar, can play again anti-theft protection effect, can arbitrarily do not opened or destroy by anyone.In the time of Open valve, often exist foreign matter can block to valve seal groove in due to pipeline, cause flashboard not close completely, at this moment can up push away gently with rotating piston, foreign matter moment is cleaned out and gets final product throttle down by water, cleaning is convenient, make the longer service life of valve, and in extensively putting goods on the market, be subject to users' consistent favorable comment, be with well economic benefit social benefit to user, between described clamping nut and valve gap, be provided with Tetrafluoro spacer, design Tetrafluoro spacer and can avoid the friction of metal between clamping nut and valve rod, reduce the keying torsion of valve, make valve opening smoothness.
In described valve rod central slot, be also provided with two O RunddichtringOs, increase the sealability of valve rod, can reduce and open and close torsion simultaneously.Between described rotating piston and valve body, be also provided with O RunddichtringO, can better increase the sealability between rotating piston and valve body, prevent that rotating piston from leaking, described rotating piston and valve body are also provided with fixed card ring, can finely prevent that rotating piston from coming off.
