Abstract
A check valve provided with sight glass mainly solves the problem that according to an existing check valve, when a transparent medium is observed, an observer cannot accurately judge the flow direction of fluid and difficulty is brought to judgment of the observer. The check valve provided with the sight glass is characterized in that an observing cavity (6) is formed in a valve body (1), observing boards (7) are arranged at the two sides of the observing cavity (6), the observing cavity (6) is communicated with a left flow channel (4) and a right flow channel (5), a valve element (3) is located in the observing cavity (6), the valve element (3) is spherical, a valve seat (2) is located between the right flow channel (5) and the observing cavity (6), and a sealing pair is formed by the spherical valve element (3) and the valve seat (2). Due to the fact that the observing cavity and the spherical valve element are arranged in the valve body of the check valve provided with the sight glass, the observer can accurately and rapidly judge the flow direction of fluid through observation of the position of the spherical valve element and the practicability of the mechanism is improved.
Description
Technical field
The utility model relates to a kind of valve, is specifically related to a kind of safety check that is provided with visor.
Background technique
In existing engineering, in many occasions, to use valve, especially, in chemical industry, hydraulic engineering, need valve as the mobile keying element of fluid.In some engineering, need to guarantee that fluid flows along fixing direction, prevent that fluid from flowing backwards, on-the-spot staff needs the very first time to grasp the flow direction of fluid.Therefore there is a kind of visor being installed on pipeline, for observing flow direction.But this visor exists certain drawback, when observing transparent medium, observer cannot judge flow direction exactly, causes difficulty to personnel's judgement.
Model utility content
In order to overcome the deficiency of background technique, the utility model provides a kind of safety check that is provided with visor, has mainly solved existing safety check when observing transparent medium, and observer cannot judge flow direction exactly, causes difficult problem to personnel's judgement.
The technological scheme that the utility model adopts is: a kind of safety check that is provided with visor, comprise valve body, valve seat, spool, in described valve body, be provided with left runner and right runner, in described valve body, be provided with observation chamber, described both sides, observation chamber are provided with access panel, and described observation chamber is communicated with left runner, right runner, described spool is arranged in observation chamber, described spool be spherical, described valve seat between right runner and observation chamber, described spherical spool and valve seat formation sealing pair.
Described inside, observation chamber is provided with four positive stop strips, and described positive stop strip is evenly distributed on spool week side.
On described valve body, be screwed gland, the standing groove forming between described gland and valve body, is provided with above-mentioned access panel in described standing groove.
Between described access panel and gland, be provided with gasket seal.
Described access panel is made by tempering Pyrex.
The beneficial effects of the utility model are: in valve body, be provided with observation chamber and spherical spool, observation personnel can determine direction of flow quickly and accurately by observing the position of spherical spool, have improved the practicability of mechanism.
Accompanying drawing explanation
Fig. 1 is the structural representation of model utility.
Fig. 2 is the front section view of model utility.
Fig. 3 is the side sectional view of model utility.
1-valve body in figure, 2-valve seat, 3-spool, the left runner of 4-, the right runner of 5-, 6-observes chamber, 7-access panel, 8-positive stop strip, 9-gland, 10-standing groove, 11-gasket seal.
Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is described further:
If Fig. 1 is in conjunction with as shown in Fig. 2 to 3, a kind of safety check that is provided with visor, comprise valve body 1, valve seat 2, spool 3, in described valve body 1, be provided with left runner 4 and right runner 5, in described valve body 1, be provided with observation chamber 6, described 6 both sides, observation chamber are provided with access panel 7, described observation chamber 6 is communicated with left runner 4, right runner 5, described spool 3 is arranged in observation chamber 5, described spool 3 is spherical, described valve seat 2 is between right runner 5 and observation chamber 6, and described spherical spool 3 forms sealing pair with valve seat 2.
Described 5 inside, observation chamber are provided with four positive stop strips 8, and described positive stop strip 8 is evenly distributed on 3 weeks sides of spool.The mobile space of restriction spool 3, makes it by intended trajectory, move, and is convenient to observe.
On described valve body 1, be screwed gland 9, between described gland 9 and valve body 1, formed standing groove 10, in described standing groove 10, be provided with above-mentioned access panel 7.Access panel 7 assembly and disassemblies are convenient.
Between described access panel 7 and gland 9, be provided with gasket seal 11.After compressing by gland 9, fluid can not leak, mechanism's good airproof performance.
Described access panel 7 is made by tempering Pyrex.Hardness is high, is difficult for crushing.
The utility model is concrete use as follows: during work, when fluid is from valve body 1 one effluents during to opposite side, spool 3 is observed chamber 6 one sides along with fluid moves to.Observation personnel can be by observing the position of spool 3 in observation chamber 6 judge the flow direction of fluid.
The beneficial effect of model utility is: in valve body, be provided with observation chamber and spherical spool, observation personnel can determine direction of flow quickly and accurately by observing the position of spherical spool, have improved the practicability of mechanism.
