Description

A kind of for the online combination valve detecting of tensimeter
Technical field
The utility model relates to a kind of valve, and especially a kind of specialty is for the online combination valve detecting of tensimeter.
Background technology
At present, domestic manometric detection is nearly all adopted tensimeter is removed, then deliver to specific inspection department and detect, judge that whether it is qualified.The program of its work, referring to Fig. 2, is first turned off switch 9, with instrument tapped joint 11 from being with externally threaded connecting pipe 10 to screw out, thereby tensimeter is pulled down, be loaded on after to be detected.
Secondly, domestic all switches 9 are nearly all cylinder iron to make now, and often use can cause switch 9 to be not closed completely, and causes leakage; Especially be installed on the tensimeter of working line in refrigeration industry, working line medium is liquefied ammonia, as leaked, may cause very serious consequence, so some units for safety, when tensimeter detects, stop normal refrigeration work, liquefied ammonia in pipe is first disposed, dismantle again tensimeter, will affect to safety and production like this, for these reasons, just be starved of a kind of simple method and accomplish manometric online detection.
Utility model content
For the weak point existing in the problems referred to above, the utility model provides a kind of specialty for the online combination valve detecting of tensimeter, after installing, just can realize manometric online detection.
For achieving the above object, the utility model provides a kind of combination valve for the online detection of tensimeter, and upper interface is positioned at the upper end of valve body, and lower interface is positioned at the lower end of described valve body, detects the side that thing import is positioned at described valve body;
Described switch A, switch B and passage are positioned at valve inner;
Described passage comprises channel C and passage D;
Below described lower interface, connect service pipe, by switch A, the channel C that vertical connecting makes progress is connected to described upper interface, described upper interface Bonding pressure table above;
The import of described detection thing is by switch B, and interface channel D is connected to described channel C.
The material of described valve body is preferably stainless steel.
Further, the interface of interface has internal thread on described, at the root of internal thread, has groove, has O-ring seal in groove.
Further, at the interface of described lower interface, there is internal thread, at the root of internal thread, there is groove, in groove, there is O-ring seal.
Further, the O-ring seal in described groove has corrosion resistance.
Further, the interface of described detection thing import has internal thread, is conveniently connected with the hose adapter that detects container.
Described switch A and switch B are preferably stop valve.
Described channel C, passage D are preferably into obtuse angle with described upper interface and are connected.
Compared with prior art, the utlity model has following advantage:
1, the utility model adopts simple structural change, in manometric signal piping, the utility model is installed, and by the control of simple switch, just can accomplish manometric online detection;
2, by using this use novel, can greatly improve the speed that tensimeter detects;
3, described combination valve internal channel is after detection, not residual medium and have influence on original duty;
4, due to manometric online detection, make the work of manufacturer continuous, efficiency improves, and when tensimeter detects, security improves greatly.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model;
Fig. 2 is the schematic diagram of prior art;
Fig. 3 is stereographic map of the present utility model.
Main element symbol description is as follows:
The upper interface of 1-lower interface 2-switch A 3-passage 4-
5-switch B 6-detects thing import 7-valve body 8-service pipe
9-switch 10-is with the tapped joint of externally threaded connecting pipe 11-
12-pipe 13-tensimeter
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.But illustrated embodiment is not as to restriction of the present utility model.
As shown in Figure 1, a kind of for the online combination valve detecting of tensimeter, upper interface 4 is positioned at the upper end of valve body 7, and lower interface 1 is positioned at the lower end of described valve body 7, detects the side that thing import 6 is positioned at described valve body 7;
Described switch A2, switch B5 and passage 3 are positioned at valve body 7 inside; Described passage 3 comprises channel C and passage D;
The material of described valve body 7 is stainless steel.
The interface of interface 4 has internal thread on described, at the root of internal thread, has groove, has the O-ring seal of corrosion resistance in groove.
Interface at described lower interface 1 has internal thread, at the root of internal thread, has groove, has the O-ring seal of corrosion resistance in groove.
The interface of described detection thing import 6 has internal thread, is conveniently connected with the hose adapter that detects container.
In conjunction with Fig. 2, the lower interface 1 of combination valve is connected service pipe 8 (now not needing switch 9) with being with externally threaded connecting pipe 10 below, above by switch A2, the channel C that vertical connecting makes progress is connected to described upper interface 4, upper interface 4 is connected with the joint of tensimeter 13 that (now manometric joint is externally threaded, as be internal thread, need to add crossover sub).Detect thing import 6 and connect the special hose that detects thing, inner by switch B5 at valve body 7, interface channel D is connected to described channel C.
The course of work of the present utility model is, when needs detect online to ducted tensimeter, switch A2 is closed, make the gas in pipeline not enter into tensimeter, detect thing import 6 places and connect the special hose that detects thing, open switch B5, make to detect thing and enter into tensimeter by passage 3 and upper interface 4, after complete all data to be collected, closing switch B5, open switch A2, the special hose that detects thing takes off from detecting thing import 6, and manometric online detection completes.
Described switch A2 and switch B5 are stop valve.
4 one-tenth obtuse angles of described passage 3C, passage 3D and described upper interface are connected.
Only as described above, be only preferred embodiment of the present utility model, such as professional who are familiar with this art. after understanding technological means of the present utility model, natural energy, according to actual needs, is changed under instruction of the present utility model.Therefore all equal variation and modifications of doing according to the utility model claim, once should still belong in the scope that the utility model patent contains.
