Abstract

The utility model discloses an integral type screw thread ball valve, including valve body, valve rod and handle, the valve body top is equipped with installs the passageway with the valve rod assorted, the valve rod is fixed through installation passageway and valve body, be equipped with the ring packing storehouse between valve body and the valve rod, the intussuseption of ring packing storehouse is filled with the V type and packs, and annular gland encircles valve rod and ring packing storehouse threaded connection, the handle passes through the nut to be fixed at the valve rod top, the handle tip is equipped with down the elbow, and the valve body is provided with and the corresponding stopper in lower elbow position. This integral type screw thread ball valve's valve body middle part filler storehouse is placed the V type and is packed, has increaseed the centering nature of valve rod and the sealing performance at valve middle part, and threaded gland may not influence middle part packing seal when changing the handle.

Description

Integral type screw thread ball valve
Technical field
This utility model relates to a kind of integral type screw thread ball valve.
Background technology
In the middle part of conventional monolithic ball valve body, filler is plain cushion formula, trim ring, handle is placed on it, fasten with nut again, in the middle part of this structure, filler is few and fragile, the screwing force that on filler armrest handle, square nut transmits seals, simple in construction but sealing property are general, if the nut loosening above handle, then middle part has the danger of leakage.
Summary of the invention
The deficiency existed in view of background technology, technical problem to be solved in the utility model is to provide the integral type screw thread ball valve of a kind of simple in construction, good seal performance, length in service life and accurate positioning.
This utility model has adopted the following technical scheme that: a kind of integral type screw thread ball valve, including valve body, valve rod and handle, described body top is provided with the installation passage matched with valve rod, described valve rod is fixed with valve body by installing passage, ring packing storehouse it is provided with between described valve body and valve rod, it is filled with V-type filler in described ring packing storehouse, annular gland ring is worn valve rod and is threadeded with ring packing storehouse, described handle is fixed on valve stem top by nut, described handle end is provided with lower elbow, and valve body is provided with the limited block corresponding with lower elbow position.
In this utility model, this integral type ball screw thread valve arrangement is simple, V-type filler it is filled with in ring packing storehouse, V-type filler in annular bin is compressed while threadeding with ring packing storehouse by annular gland, substantially increase sealing property, only need loose nut when changing handle, do not affect the filler in filling container, extending the service life of valve, limited block makes handle location more accurate.
Accompanying drawing explanation
Fig. 1 is the cross-sectional view of integral type screw thread ball valve of the present utility model.
Detailed description of the invention
With reference to shown in Fig. 1, the integral type screw thread ball valve that this utility model provides, including valve body 1, valve rod 2 and handle 3, described valve body 1 top is provided with the installation passage 4 matched with valve rod, described valve rod 2 is fixed with valve body 1 by installing passage 4, it is provided with ring packing storehouse 5 between described valve body 1 and valve rod 2, it is filled with V-type filler 6 in described ring packing storehouse 5, it is provided with female thread in described ring packing storehouse 5 to match with the external screw thread set by annular gland 7, annular gland ring 7 is worn valve rod and is threadeded with ring packing storehouse 5, described handle 3 is fixed on valve rod 2 top by nut 8, described handle end is provided with lower elbow 9, valve body is provided with the limited block 10 corresponding with lower elbow 9 position.
In the present embodiment; annular gland 7 and the filler 6 in ring packing storehouse 5 compact siro spinning technology and compression annular filling container; substantially increase the sealing property of valve; the most preferably filler in the middle part of protection; extend the service life of valve; the lower elbow 9 of described handle contacts with the limited block 10 on valve body, the most now valve wide open or fully closed, makes handle 3 position more accurate.
