Abstract
The utility model relates to a valve convenient to observe. The valve convenient to observe comprises a valve deck, at least one probe hole is formed in the valve deck, the probe holes are evenly distributed around the center of the valve deck, and hole covers are arranged on the probe holes. Due to the fact that at least one probe hole is formed in the valve deck, inner conditions of the valve can be observed without demounting the valve, and the valve convenient to observe is simple, convenient and fast.
Description
Technical field
The utility model relates to a kind of valve, especially a kind of valve of being convenient to observe.
Background technique
Valve is the crucial controlling component in the fluid delivery system, have by, adjusting, water conservancy diversion, prevent functions such as adverse current, voltage stabilizing, shunting or overflow pressure release.The valve that is used for liquid control system, from the simplest stop valve to very complicated robot control system(RCS) used various valves, its kind and specification are quite various.Valve can be used for controlling flowing of all kinds fluids such as air, water, steam, various Korrosionsmedium, mud, oil product, liquid metal and radiating medium.
Existing valve mechanism, its structural representation as shown in Figure 1.Drive valve plate by the handwheel rotation and move up and down, realize closing or opening of valve like this.But such valve in use, is difficult for the observation inner case, often needs could observe inner case after the dismounting, very trouble.
The model utility content
The deficiency that the utility model exists at prior art just provides a kind of valve of being convenient to observe.
For addressing the above problem, technical solution adopted in the utility model is as follows:
The described valve of being convenient to observe comprises valve gap, and described valve gap is provided with at least one exploration hole.
Further, described exploration hole evenly distributes around described valve gap center.
Further, described exploration hole is provided with port lid.
The utility model compared with prior art, implementation result of the present utility model is as follows:
The valve of being convenient to observe described in the utility model by at least one exploration hole is set, not needing to dismantle under the situation of valve, just can be observed the valve inner case on valve gap, simple and efficient.
Description of drawings
Fig. 1 is the structural representation of existing valve described in the background technique;
Fig. 2 is the structural representation of the valve gap of a kind of valve of being convenient to observe of the utility model.
Embodiment
Content of the present utility model is described below in conjunction with specific embodiments.
See also Fig. 1, Fig. 1 is the structural representation of existing valve described in the background technique.
Existing valve comprises valve body 1, valve gap 2, valve plate 3, valve rod 4, valve plate seal ring 5, gland 6, handwheel 7 and valve seals 8.The inside of valve body 1 is provided with bigger cavity, and there is unlimited opening at two ends, is convenient to entering and flowing out of fluid like this.Valve gap 2 is installed in the top of valve body 1, and valve gap 2 inside are provided with certain cavity, and the cavity of this cavity and valve body 1 inside mates mutually.Be provided with valve seals 8 between valve gap 2 and the valve body 1,, utilize the locking nut (not shown) that the three tightly is locked together in case fluid is revealed.The oral area of valve gap 2 upper ends is less, and the oral area inboard is provided with internal thread.
Bigger cavity central position at valve body 1 is equipped with valve plate 3, between the both sides of valve plate 3 and the valve body 1 valve plate seal ring 5 is installed, and valve plate 3 is flat tabular, and its size is bigger slightly than the cavity in the valve body 1, just in time can stop fluid to flow in valve body 1.Valve rod 4 is installed directly over the valve plate 3, and valve rod 4 is provided with outside thread.Valve rod 4 passes the oral area of valve gap 2 upper ends, and the internal thread of outside thread on the valve rod 4 and valve gap 2 oral areas is meshing with each other.
Be provided with gland 6 in valve gap 2 upper ends, gland 6 neutral positions are provided with center hole, gland 6 and valve gap 2 screw-threaded couplings.Gland 6 upper ends are provided with handwheel 7, and handwheel 7 centers are provided with elongated center-pole 7a, and center-pole 7a passes the center hole of gland 6, are connected and fixed with valve rod 4.
When rotation hand wheel 7, center-pole 7a drives valve rod 4 rotations, and under valve gap 2 oral area screw-thread fit, valve rod 4 rotations also move up and down, and drive moving up and down of valve plate 3 by moving up and down of valve rod 4 like this, finally realize the open and close of valve.
See also Fig. 2, Fig. 2 is the structural representation of the valve gap of a kind of valve of being convenient to observe of the utility model.
The valve of being convenient to observe described in the utility model is to improve on existing valve mechanism basis, and it improves component and comprises: valve gap 2 '.
A kind of valve of being convenient to observe described in the utility model, comprise valve gap 2 ', at least one exploration hole 9 of described valve gap 2 ' be provided with, described exploration hole 9 evenly distributes around described valve gap 2 ' center, described exploration hole 9 is provided with port lid 10.
When not needing to observe, close port lid 10, prevent exploration hole 9 laying dusts.When needs are observed, open port lid 10, observe inner cases by exploration hole 9, under the darker situation in inside, open two exploration holes simultaneously, at an exploration hole observation, another peephole printing opacity.
By valve gap 2 ' at least one exploration hole 9 is set, not needing to dismantle under the situation of valve, just can observe the valve inner case, simple and efficient.
Above content is the detailed description of the utility model being done in conjunction with concrete preferred implementation, can not assert that the concrete enforcement of the utility model only limits to these explanations.For the utility model person of ordinary skill in the field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to the scope of the utility model protection.
Claims (3)
1. a valve of being convenient to observe comprises valve gap (2 '), it is characterized in that, described valve gap (2 ') is provided with at least one exploration hole (9).
2. the valve of being convenient to observe as claimed in claim 1 is characterized in that, described exploration hole (9) evenly distributes around described valve gap (2 ') center.
