Abstract
A dual-purpose stop valve comprises a valve body capable of being connected between fluid pipelines in series. A stop valve element is arranged on the valve body. A hand wheel screw rod driver is connected to the stop valve element. The dual-purpose stop valve is characterized in that a chamber is arranged in the portion, below the inlet end, of the valve body and the opening direction of the chamber and the direction of the stop valve element are not in the same longitudinal axial face; a lower stop valve element is installed in the chamber and is connected with a lower hand wheel screw rod driver; the valve body is of a Z shape. The dual-purpose stop valve has the advantages that two stop valves are integrally designed, the structure is compact, the sealing performance is good, installation and maintenance are convenient, the service life of a pipeline system and the service life of the valve are prolonged; the valve body is of the Z shape, so that the filtering effect is improved, and the service life of the stop valve elements is prolonged.
Description
Technical field
The utility model relates to a kind of stop valve for Control Engineering pipeline fluid flow, relates in particular to a kind of Dual-purpose cutoff valve.
Background technique
In existing pipe-line system, there is the flowing medium of impurity many, impurity particle in some flowing medium is larger, if impurity rests on Sealing position in pipe-line system, the obturation effect that affects valve that can be serious, the impurity of processing in flowing medium generally adopts filter tap is installed before stop valve, can filter in advance the impurity in flowing medium, the sealing effect of the stop valve at protection rear, but the shortcoming of this method is due to two valves of filter tap and stop valve will be installed, to the integrity of pipeline, destroy more serious, and installation and maintenance is all inconvenient, reduced the working life of pipe-line system and valve.
Summary of the invention
The purpose of this utility model is to provide a kind of compact structure, favorable sealing property, and installation and maintenance is convenient, can improve the Dual-purpose cutoff valve of pipe-line system and life of valve.
For achieving the above object, the technological scheme that the utility model adopts is:
A kind of Dual-purpose cutoff valve, comprising: can be serially connected in the valve body between fluid line, on valve body, be designed with cut-off spool, on cut-off spool, being connected with handwheel leading screw drives, its feature is: in the valve body below the entrance point of described valve body, be designed with chamber, the direction of the opening direction of chamber and described cut-off spool is not on a longitudinal axial plane; Lower cut-off spool is installed in chamber, on lower cut-off spool, is connected with lower handwheel leading screw and drives.
According to above-mentioned Dual-purpose cutoff valve, its feature is: described valve body is " Z " font.
The utility model has the advantages that: the utility model is two shutoff valve designs in one, and structure is compacter, favorable sealing property, installation and maintenance is convenient, the working life of having improved pipe-line system and valve; Valve body is designed to " Z " font, has increased filtering effect, has improved the working life of cut-off spool.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In accompanying drawing
1, lower handwheel leading screw driving 2, lower cut-off spool 3, chamber 4, valve body 5, cut-off spool 6, handwheel leading screw drive.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the utility model is further described:
A kind of Dual-purpose cutoff valve, as shown in Figure 1, comprising: can be serially connected in the valve body 4 between fluid line, on valve body 4, be designed with cut-off spool 5, on cut-off spool 5, be connected with handwheel leading screw and drive 6, its feature is: in the valve body below the entrance point of described valve body 4, be designed with chamber 3, the direction of the opening direction of chamber 3 and described cut-off spool 5 is not on a longitudinal axial plane; Lower cut-off spool 2 is installed in chamber 3, on lower cut-off spool 2, is connected with lower handwheel leading screw and drives 1.
In the present embodiment, valve body 4 is " Z " font.
The beneficial effects of the utility model are: the utility model is two shutoff valve designs in one, and structure is compacter, favorable sealing property, and installation and maintenance is convenient, the working life of having improved pipe-line system and valve; Valve body is designed to " Z " font, has increased filtering effect, has improved the working life of cut-off spool.
Embodiment recited above is described preferred implementation of the present utility model; not design of the present utility model and protection domain are limited; do not departing under the prerequisite of the utility model design concept; various modification and improvement that in related domain, common engineers and technicians make the technical solution of the utility model, all should fall into protection domain of the present utility model.
