Abstract
A water heating butterfly valve is characterized in that a valve rod is fixed in a middle hole of a valve body, a rotating handle is arranged on the valve rod, a long-tube-shaped sealing sleeve is arranged between the middle hole of the valve body and the valve rod, the tightness of a valve cover limits the friction force of the sealing sleeve on the valve rod, a butterfly-shaped valve core is arranged at the lower end of the valve rod, a valve nozzle is arranged on the inner wall of the valve body, and an extension section used for being connected with a union is arranged. The butterfly valve has simple and reasonable structure, convenient operation and low cost, and can be used for heating pipelines with small pressure difference.
Description
The utility model relates to a kind of warming installation valve body.
Dish valve difficulty of processing of the prior art is bigger, quality of fit requires high, the positioning means complexity, useless in the convenient prolonged section that connects, in the hot-water heating facility, use some only to be used to regulate the valve of flow, and the higher valve of precision is unnecessary, so, cause the unnecessary utilization of highi degree of accuracy valve.
The purpose of this utility model provides a kind of rational hot-water heating dish valve simple in structure that can regulate flow.
The purpose of this utility model realizes by following measure, valve rod 6 is arranged in the pilot hole of valve body 1, turning handle 3 is arranged at valve rod top, dish-shaped spool 5 is fixed in the bottom of valve rod 6, is filled with the very strong stuffing box gland of frictional force 2 between the pilot hole of valve rod 6 and valve body, and valve gap 9 compresses it, and can adjust friction level, the middle bore portion of valve body 1 has the valve nozzle that is sealed and matched with dish-shaped spool 5, and this valve nozzle is positioned at the corresponding disc valve core segment of valve body mesopore inwall, and both sealings do not need precision too high.The valve body impact force little because of pressure reduction in the water heating device is little, when adjusting flow, rotates turning handle 3 and gets final product, and fixed locating stud 4 on the turning handle, and the elongate tubular stuffing box gland 2 in the pilot hole makes valve rod 6 location.
Above-mentioned valve also can have prolonged section at an end internal thread connecting port place of valve body, and this prolonged section matches with union 7, and the outside thread of prolonged section combines with the internal thread of union, and is fluted on the inwall of prolonged section end, between the two by seal ring 8 sealings.This prolonged section is used for connecting with heating sheet and pipeline easily.
Narrate below in conjunction with drawings and Examples.
Fig. 1 is the structural drawing of dish valve.
Fig. 2 is the structural drawing that the dish valve of prolonged section is arranged.
With reference to Fig. 1 is an embodiment of the present utility model, dish-shaped spool 5 is fixed in the bottom of valve rod 6, the strong elongate tubular stuffing box gland 2 of frictional force is arranged between the pilot hole of valve rod 6 and valve body 1, compressed by valve gap 9, bore portion has the valve nozzle that is sealed and matched with dish-shaped spool 5 in the valve body 1.This valve is used on the return pipe of heating pipeline, is subjected to water slug outer little, only regulates water flow and controls temperature and get final product, and uses this valve to reduce cost greatly, and rational in infrastructure, easy to operate.
Claims (2)
1, a kind of hot-water heating dish valve, comprise valve body 1, valve rod 6 and turning handle 3, the fixing dish-shaped spool 5 in bottom that it is characterized in that described valve rod 6, the strong elongate tubular stuffing box gland 2 of frictional force is arranged between the pilot hole of valve rod 6 and valve body 1, seal ring is compressed by valve gap 9, and bore portion has the valve nozzle that is sealed and matched with dish-shaped spool 5 in the valve body 1.
2, hot-water heating dish valve according to claim 1 is characterized in that an end internal thread connecting port of valve body 1 has prolonged section to match with union 7, and this prolonged section has outside thread, and the end inwall is fluted, and seal ring 8 is arranged between this prolonged section and union.
