Abstract

The utility model discloses a cock-type valve, comprising a valve body, an inlet of the valve body, an outlet of the valve body, a valve handle and a valve rod; wherein, the valve core is arranged in the cavity of the valve body; the inlet and the outlet of the valve body are respectively intersected with the passage of the valve body cavity. The utility model is characterized in that: two outlets of the valve body are arranged on the valve body; the valve core is shown as a hollow spherical shape and three passages are arranged and can respectively be spirally matched with two outlets and one inlet of the valve body; a sealing part is arranged inside a gap between inner wall of the valve body cavity and the valve core. Two outlets of the valve body are arranged at the same plane and the axle angle of the central axis for the two outlets is a right-angle. The utility model has the advantages that: when a ball type valve core rotates to a certain angle, two other gas passages control the outlets of the valve body according to the rule of completely close or one start and one close except that the intake passage is always communicated with the inlet of the valve body; therefore, the valve is especially suitable when prior air compressor needs to import gas to one operation point or two operation points.

Description

The cock type three-way valve door

Affiliated technical field

The utility model belongs to a kind of valve, relates in particular to the valve that the control conveyance conduit opens and closes on a kind of gas holder that is arranged on air compressor.

Background technique

Valve mechanism before the utility model is made generally is made up of valve body, valve body import, valve outlet, valve handle and valve rod, spool etc.Spool places in the valve body chamber, and valve body import and valve outlet cross with valve body chamber passage respectively, and spool opens and closes gas-liquid channel under valve handle and valve rod control.

At present, there is such problem in actual use, if that is: air compressor is wanted simultaneously when two setting conveying gas, based on existing valve mechanism two valves must be set then, can imagine, valve is provided with manyly more, annex also increases manyly more, not only make pipeline complicated, also can increase rate of fault, influence reliability.

Summary of the invention

For overcoming existing valve when air compressor needs simultaneously to two setting gas transmissions, the deficiency of two valves is installed, the utility model provides a kind of structure novel plug valve, after making existing air compressor dispose a valve of this structure, not only can be easily to a setting gas transmission, can also be simultaneously to two setting gas transmissions.

The technological scheme that its technical problem that solves the utility model adopts is:

The structure of this plug valve is made up of valve body, valve body import, valve outlet, valve handle and valve rod, spool etc., spool places in the valve body chamber, valve body import and valve outlet cross with valve body chamber passage respectively, and its structure outline is: valve body is provided with two valve outlets; Spool is shaped as hollow sphere, and is provided with three passages, and three passages can revolve and join with two valve outlets, a valve body import respectively; Gap between valve body cavity wall and the spool is built-in with Sealing.

During concrete enforcement, the shape of spool also can adopt the structure of similar hollow sphere, as: hollow cylindrical or hollow round table shape etc.

During concrete enforcement, two valve outlets are positioned at same plane, and its both medial axis angle is the right angle.

The beneficial effects of the utility model are, when the ball type valve core rotates to a certain angle, except that gas-entered passageway all the time with the valve body import communicates, other two gas channels then open a rule control valve body outlet of closing or opening entirely according to full cut-off,, therefore, existing air compressor is if need be particularly suitable for this valve of adapted when a setting or two setting gas transmissions.

Description of drawings

Fig. 1 is an embodiment's of the utility model a main TV structure vertical profile schematic cross-section;

Fig. 2 among Fig. 1 along the schematic cross-section of analysing and observe of A-A line.

Embodiment

The utility model is described in further detail by embodiment below in conjunction with accompanying drawing.

Referring to Fig. 1, Fig. 2.Sequence number is represented respectively among the figure: valve body import 1, valve body 2, valve outlet 3,10, Sealing 4,5, spool 6, valve gap 7, valve rod 8, valve handle 9, passage 11.

Spool 6 hollow sphere (certainly, the spool shape can also be analogous shapes such as hollow cylindrical or hollow round table shape, and its cambered surface and valve outlet 3,10 revolve join), its three passages 11 revolve with 3,10, one valve body imports 1 of two valve outlets respectively joins, that is: spool 6 is under 8 controls of valve handle 9, valve rod from left to right or during the right-to-left rotation, two kinds of situations can take place, the one, foot passage communicates with valve body import 1 all the time; Two is that two valve outlets 3,10 are provided with (that is: both medial axis angles are the right angle) owing to be horizontal sextant angle 90 degree, there is full cut-off, to open one between in addition two passages of spool 1 and two valve outlets 3,10 and closes or open full phenomenon (Fig. 1, position shown in Figure 2 is in the state that opens entirely), when opening state entirely, air compressor air storage tank is to two settings while air feed.Certainly, between satisfied two passages and two valve outlets 3,10, there is full cut-off, to open under the condition of a phenomenon of closing or opening entirely, also can be with two valve outlets 3,10 by corresponding angle setting.

During assembling, valve outlet 3,10, valve body import 1, valve gap 7 spins with valve body 2 sealings; Valve handle 9 is screwed in valve rod 8 tops, and valve rod 8 passes valve gap 7 back and links with spool 6, and Sealing 4,5 is assemblied in the gap between valve body cavity wall and the spool 6, seals.

Claims

1. a plug valve comprises valve body (2), valve body import (1), valve outlet, valve handle (9) and valve rod (8) thereof, spool (6); Spool (6) places in the valve body chamber, and valve body import (1) and valve outlet cross with valve body chamber passage respectively, it is characterized in that: valve body (2) is provided with two valve outlets (3,10); Spool (6) is shaped as hollow sphere, and is provided with three passages (11), and three passages (11) can revolve and join with two valve outlets (3,10), a valve body import (1) respectively; Gap between valve body cavity wall and the spool (6) is built-in with Sealing (4,5).

2. a kind of plug valve according to claim 1 is characterized in that: the shape of spool (6) also can adopt the structure of similar hollow sphere, as: hollow cylindrical or hollow round table shape etc.
