It connects, or is integrally connected；It can be mechanical connection, be also possible to be electrically connected；It can be directly connected, intermediate matchmaker can also be passed through
Jie is indirectly connected, and can be the connection inside two elements.It for the ordinary skill in the art, can be with concrete condition
Understand the concrete meaning of above-mentioned term in the present invention.
Fig. 1-4 is please referred to, the present invention provides a kind of technical solution：A kind of valve, including valve body 1, handwheel 5 and pass through spiral shell
Silk is fixedly mounted on the valve deck 4 at the top of valve body 1, and the lower end outside of the valve body 1 is provided with water inlet pipe 2, the water inlet pipe 2 it is upper
It is connected between surface and 1 upper end of valve body outside by return pipe 12,1 bottom of valve body, which is screwed, is equipped with outlet pipe
3, one end inner wall being connected to inside the outlet pipe 3 and valve body 1 is equipped with internal screw thread 10, and being internally embedded for valve body 1 is provided with
Threaded stem 6, threaded hole 13 is offered on the valve deck 4, and one end of the threaded stem 6 passes through the threaded hole 13 and the hand
5 connection of wheel, the other end are fixedly installed with plunger 7, and 7 outer surface of plunger is equipped with external screw thread 9, and the threaded stem 6 is close to column
One end of plug 7 is arranged with piston 8, and part of the threaded stem 6 between valve deck 4 and piston 8 is cased with spring 11.
More specifically, 1 inner hollow of valve body in a tubular form, and with water inlet pipe 2, outlet pipe 3 be connected, return pipe 12 will
Valve body 1 and water inlet pipe 2 are connected, and the piston 8 is bonded with 1 tubular inner wall of valve body, it is preferred that outlet pipe 3 is L-shaped, the valve
Junction between body 1 and valve deck 4, water inlet pipe 2 and outlet pipe 3 is designed with rubber gasket.
More specifically, the threaded hole 13 engages with 6 threaded adapter of threaded stem, is arranged in described 3 one end of outlet pipe
The internal screw thread 10 of inner wall is adapted to and can engage with the external screw thread 9 of 7 outer surface of plunger, by rotating clockwise or counterclockwise handwheel 5, comes
Control plunger 7 rises or falls, to achieve the effect that the valve opening or closing.
Preferably, arc-shaped curved surface is arranged in outer surface at the end of the plunger 7, reduction is opening or closing the valve
When, to the resistance of the plunger 7, which can be is weldingly fixed in threaded stem 6 liquid in valve.
Working principle：Assuming that clockwise rotation handwheel 5 is to close the valve.Rotating counterclockwise handwheel 5 is to open the valve,
When rotating counterclockwise handwheel 5, threaded stem 6 rotates rising in the threaded hole 13 on valve deck 4, while plunger 7 is in outlet pipe 3
The internal screw thread 10 of end is synchronized with threaded stem 6 under acting on and rotates upwards, at this point, piston 8 squeezes the liquid inside valve body 1 upwards
Pressure, the liquid most flow back into water inlet pipe 2 through return pipe 12 afterwards, when the external screw thread 9 in 7 outside face of plunger is detached from 3 end of outlet pipe
Internal screw thread 10 when, the valve opening, when preliminary open (as shown in Figure 3), since the end of plunger 7 does not take off completely
Water pipe 3 is separated out, during plunger 7 is gradually increasing, liquid is gradually increased through the flow of outlet pipe 3, until 7 end of plunger is complete
Total detachment outlet pipe 3, and when leaving 2 nozzle upper end of water inlet pipe, maximum flow, the valve fully opens at this time, threaded hole 13 with
Threaded stem 6 engages, and plunger 7 will not land, and part of the threaded stem 6 between valve deck 4 and piston 8 is cased with spring 11,
During opening the valve, spring 11 gradually reduces, and under the tension force effect of spring 11, reduces the shaking of threaded stem 6, when
When rotating clockwise handwheel 5, threaded stem 6 rotates decline in the threaded hole 13 on valve deck 4, and plunger 7 is at 3 end of outlet pipe
Internal screw thread 10 block 3 nozzle of outlet pipe, when completely closing the valve (as shown in Figure 4), piston 8 with it is tight at the end of outlet pipe 3
Closely connected conjunction solves seepy question under this dual-seal.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
