Touching.
By using above-mentioned technical proposal, when rotating handle opens closure steam inlet by the elevating movement of valve rod, valve
Core and valve rod link, so that steam pipework inner wall is cleaned with the cleaning head on movable valve plug, when being passed through steam, steam pipework
Middle steam pressure, which presses to cleaning head, is adjacent to spool side, steam will not be prevented to enter Builking cavity, if when closure steam inlet, valve
Core end is not contradicted with steam jet exit, and the pressure in Builking cavity is by cleaning head to being adjacent to one side pressure of steam pipework inner wall at this time
Tightly, so that the material in Builking cavity be made to be not easy to plug steam pipework.
The utility model is further arranged to: the steam jet exit has circular conical surface to steam pipework internal stretch, institute
Circular cone is stated to expand away from steam jet exit.
By using above-mentioned technical proposal, the cone of inner wide and outer narrow accelerates steam from the steam pipework rate of outflow, steams
When vapour enters Builking cavity by steam jet exit, the material in Builking cavity is not easy to regurgitate steam lead road, steam jet exit
It is open smaller, the material in Builking cavity is further made to be not easily accessible steam pipework.
The utility model is further arranged to: the steam pipework outer wall is equipped with the external screw thread connecting with Builking cavity, described
External screw thread is equipped with gasket seal close to valve seat one end.
By using above-mentioned technical proposal, steam pipework is threadedly coupled with Builking cavity, by gasket seal, is further strengthened
Leakproofness, simple in construction, easy to disassemble and assemble, exploitativeness is strong.
The utility model is further arranged to: the bonnet for limiting stem position is fixedly connected with above the valve seat, it is described
Bonnet is connect with threaded stem.
By using above-mentioned technical proposal, valve rod wears bonnet and extends out along to far from valve seat one end, valve rod and valve
Cap thread connection makes valve rod be not susceptible to deviate, and convex block and bonnet further define the motion profile of valve rod, increase valve rod
Stability.
The utility model is further arranged to: the valve rod is equipped with the limit of limitation bulge loop move distance close to handle one end
Block.
By using above-mentioned technical proposal, the maximum distance of bulge loop decline is defined, convex block drops to rigid when maximum distance
It is good to completely enclose steam inlet, make the steam of steam inlet be not easy to flow into longitudinal valve chamber on the upside of bulge loop, to improve dress
The safety set.
The utility model is further arranged to: the limited block upper end is equipped with mounting blocks, and the handle center is fixedly attached
On mounting blocks, the mounting blocks threaded upper ends are connected with acorn nut.
By using above-mentioned technical proposal, handle is matched with mounting blocks, and handle and mounting blocks is made to link, when rotational handle
It being not susceptible to dally, handle and mounting blocks are further compacted by acorn nut, and so that handle is not easy upper underdrive in rotary course,
Improve the stability of handle.
The utility model is further arranged to: it is regular polygon that the handle, which holds side, and edges and corners are provided with rounded corner.
By using above-mentioned technical proposal, round handle easily skids when rotating, it has not been convenient to worker operation, regular polygon setting
Enable worker preferably to grab handle to rotate, rounded corner makes the water chestnut of regular polygon be not easy to scratch worker, improves operation
Safety.
In conclusion the utility model has the following beneficial effects:
1. passing through the setting of valve seat, valve rod and spool, material is not easy to plug steam pipework when can play addition steam
Effect；
2. the effect of cleaning steam pipework inner wall can be played by the setting of cleaning assemblies；
3. can play makes valve rod be not susceptible to the effect that offset improves valve rod stability by the setting of bonnet.

Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
Referring to Fig.1, a kind of angie type steam disclosed by the utility model sprays needle-valve, including valve seat 1, and 1 internal screw thread of valve seat connects
It is connected to valve rod 2,2 top of valve rod is equipped with mounting blocks 23, and handle 25 is socketed on mounting blocks 23, and it is regular polygon that handle 25, which holds side,
And edges and corners are provided with rounded corner, and the acorn nut 24 of fixed handle 25 is equipped at the top of valve rod 2.1 side wall of valve seat be equipped with steam into
Mouth 11,1 upper end of valve seat are equipped with the bonnet 13 for limiting 2 position of valve rod, are fixedly connected with limited block 22,1 bottom of valve seat on bonnet 13
Equipped with steam pipework 3,3 outer wall of steam pipework is equipped with the external screw thread 33 of Builking cavity connection, and external screw thread 33 is equipped with close to 1 one end of valve seat
Gasket seal 34.
Referring to Fig. 2,2 bottom of valve rod is equipped with the bulge loop 21 of control 11 size of steam inlet, and pedestal upper end is equipped with for bulge loop 21
Longitudinal valve chamber 12 of lifting.3 lower end surface of steam pipework is equipped with steam jet exit 32, and steam jet exit 32 is to steam pipework 3
Inner wall is extended with circular conical surface, and circular cone is expanded away from steam jet exit 32.Valve is equipped in steam pipework 3 along its length
Core 31,31 upper end of spool are fixedly connected on 21 bottom of bulge loop, when bulge loop 21 completely encloses steam inlet 11,31 tail portion of spool with
Steam jet exit 32 is inconsistent, is not easy the material in Builking cavity by back-pressure steam lead road 3, to make steam pipework 3 not
Easily blocking.31 lower end of spool is equipped with cleaning assemblies 311, and cleaning assemblies 311 includes being fixedly connected on spool 31 to steam pipework 3
Inner wall extends tapered cleaning head 312, and cleaning head 312 is abutted with 3 inner wall of steam pipework, and rotational handle 25 adjusts steam inlet
When 11 size, spool 31 drives cleaning head 312 to do and moves up and down, can clear up 3 inner wall of steam pipework.
The implementation principle of the present embodiment are as follows: steam is passed through steam inlet 11, rotational handle 25 rises bulge loop 21, adjusts
The size of steam inlet 11, to adjust steam flow, steam flows into steam pipework 3, high steam impact through steam inlet 11
The circular conical surface of cleaning assemblies 311 makes the circular conical surface of cleaning assemblies 311 be adjacent to spool 31, and then high steam is through vapor injection port
It projects, into Builking cavity, makes material be not easy to regurgitate blocking steam pipework 3, after the completion of adding steam, rotating handle 25 makes convex
Ring 21 declines, and spool 31 declines with bulge loop 21 during bulge loop 21 declines, when bulge loop 21 completely encloses steam inlet 11
When, spool 31 is inconsistent with vapor injection port, is connected to Builking cavity not with steam pipework 3, and then make material in Builking cavity not
Easily enter steam pipework 3, while during bulge loop 21 declines, bulge loop 21 and spool 31 are interlocked, and spool 31 drives cleaning head
312 move downward, and can clean 3 inner wall of steam pipework.
