Specific embodiment
Below in conjunction with the accompanying drawings this utility model embodiment is described further.
As shown in figure 1, a kind of precision inside screw nonrising stem type gate valve, the valve gap 2 including valve body 1, being fixed on valve body 1 upper end, located at valve
In body 1 and valve gap 2 and be based in the valve rod 3 outside valve gap 2 and the handwheel 4 located at valve rod 3 upper end, the bottom of described valve rod 3
It is threaded with flashboard 5 by T-shaped, described flashboard 5 is in inverted cone, the contact surface of described valve gap 2 and valve rod 3 is provided with recessed
Groove 6, described groove 6 lower end is provided with valve seat 7, and described groove 6 upper and lower surface is provided with anti-wear gasket 8, described valve rod 3 sets
There is the step 9 matching with above-mentioned groove 6, it is orthohexagonal boss 10 that described valve gap 2 upper center is provided with section.Back taper
The design of shape flashboard 5 effectively reduces the sealing surface of flashboard 5, thus allowing the overall volume reducing flashboard 5, flashboard 5 diminishes
Afterwards, the volume of valve body 1 can correspondingly be reduced to a certain extent, the lifting surface area of such valve body 1 have also been smaller, identical in wall thickness
In the case of, make valve body 1 obtain further reinforcing, also can make the more compact of valve body 1 change simultaneously, save floor occupying area,
Save material on the premise of ensureing trafficability performance, reduces cost.
Preferably, described valve body 1 and valve gap 2 are threaded connection, and are provided with sealing gasket at valve body 1 and the sealing of valve gap 2
11.Utilize between valve body 1 and valve gap 2 and threaded, add the regular hexagon boss 10 on valve gap 2, it is possible to use spanner blocks
Regular hexagon boss 10 carrys out rotary valve cover 2, makes to reach zero leakage between valve gap 1 and valve body 2 in the presence of fitted seal pad 11.Valve
Adopt between body 1 and valve gap 2 and threaded, there is structure simply, the convenient advantage of demolition and maintenance.
Preferably, described flashboard 5 lower end is connected with cylindrical valve ball 12, and described cylindrical valve ball 12 bottom is provided with convex
Edge 13, described valve body 1 entirety is in the I shape of horizontally set, and its horizontal center position is provided with the runner 14 for flow of media,
The center subordinate end of described runner 14 is provided with cylindrical shrinkage pool 15, and it is straight that described cylindrical shrinkage pool 15 upper end diameter is less than lower end
Footpath, the making material soft rubber of described valve ball 12.Flange 14 on valve ball 12 less times greater than runner inner wall upper concave hole 15, so
In cooperation, the valve ball 12 of soft rubber plays the effect of interference fit, improves sealing, reaches the effect of zero sealing.
Preferably, described runner 14 is cylinder, and the length of described T-shaped screw thread is more than the diameter length of runner 14,
Described runner 14 inwall is provided with FBE or skin of paint.FBE or skin of paint are it can be avoided that described stream
The inwall in road 14 is subject to corrosion and the damage of medium fluid, extends its service life.
When needing to open gate valve, hold handwheel 4 rotate counterclockwise valve rod 3, because the step 9 on valve rod 3 can block
On the groove 6 of valve gap 2, the principle further according to left-handed T-shaped screw thread, so that flashboard 5 rises to a certain extent, is opened with reaching gate valve
The effect opening, due to valve rod, 3 rotate without rising, and can effectively reduce the whole height of gate valve, save installing space；
In the same manner, it is only necessary to hold handwheel 4 dextrorotation rotating valve rod 3 so that it may so that flashboard 5 decline comes when needing closing gate valve
Reach the effect of closing, its control process is simple, and more laborsaving.
This precision inside screw nonrising stem type gate valve good seal performance, small volume, structure is simple, more saves former material under identical trafficability performance
Material, low cost, and ram seal face lifting surface area is little, open more laborsaving, have practical and convenient, safe and reliable it is easy to push away
Wide the advantages of.
Every technical staff's notice：Although this utility model describes according to above-mentioned specific embodiment, this
The invention thought of utility model is not limited to that utility model, the repacking of any utilization inventive concept, all will include this specially
In sharp scope of patent protection.
