Abstract
The utility model discloses a special valve for a pressure gauge, which comprises a valve body and a valve core. A pressure gauge screw thread is arranged at one end of the valve body, and a pipeline screw thread is arranged at the other end. Radial threads of the valve core are installed on the valve body which is provided with a damping hole so that the pressure gauge is communicated with the pipeline. The valve body is provided with two pressure relief holes; and one pressure relief hole is arranged at the pressure gauge screw thread end while the other pressure relief hole is arranged at the pipeline screw thread end. The valve body is further provided with an evacuation screw and an evacuation hole. The evacuation screw is communicated with the damping hole, and the evacuation hole is communicated with the evacuation screw hole. In the special valve for the pressure gauge, the valve body is provided with the pressure gauge screw thread and the pipeline screw thread so that the pressure gauge can be directly installed on the special valve. Compared with prior art, the special valve for the pressure gauge has the advantages of reasonable structure, simple installation, safety, reliability and the like and has the damping effect.
Description
Technical field
The utility model relates to a kind of valve, particularly a kind of pressure gauge special valve.
Background technique
The installation screw thread of ordinarily manometer is the fine thread of M20 * 1.5, and the valve screw thread of general DN20 is the coarse-pitch thread of M20.Traditional setting pressure table method is pressure gauge stand of special earlier processing, an end setting pressure table, and the other end is installed on the valve, and valve connects with the measured medium pipeline again.If without the pressure gauge stand, also pressure gauge can be forced screwin during the setting pressure table, but the fine thread of meeting rupture pressure table makes it poorly sealed, causes the medium seepage easily.If the working pressure gauge stand, not only waste material, and installation trouble.When surveying pulsating pressure, the impact force of its pressure surge usually can shatter pressure gauge in addition.If throttle down or fit badly not, pressure medium can spray in the process of dismounting pressure gauge or valve, can damage the operator.
The model utility content
The technical problems to be solved in the utility model is for overcoming above-mentioned deficiency, and a kind of simple in structure, fitting operation pressure gauge special valve easily is provided.
The utility model is taked following technical measures: a kind of pressure gauge special valve, comprise valve body, spool, and described valve body one end is provided with the pressure gauge screw thread, the other end is provided with the pipeline screw thread, spool radially screw thread is installed on the valve body, and valve body is provided with damping hole, makes pressure gauge be connected with pipeline.
Described valve body is provided with 2 relief holes, and one is arranged on pressure gauge screw thread end, and another is arranged on pipeline screw thread end.
Also be provided with cleaning screw and relieving device on the valve body, described cleaning screw hole is connected with described damping hole, and relieving device is connected with the cleaning screw hole.
The beneficial effects of the utility model are owing to be provided with pressure gauge screw thread and pipeline screw thread on valve body, make pressure gauge to be directly installed on this special valve.Relief hole at first oozes out medium from relief hole, avoid continuing dismounting and make the medium ejection and hurt sb.'s feelings, and cleaning screw can be laid down the valve internal pressure easily.Compared with prior art, have advantages such as rational in infrastructure, simple installation, safe and reliable and damping function.
Description of drawings
Fig. 1 is a kind of embodiment's of the utility model a structural representation
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in the figure, a kind of pressure gauge special valve comprises valve body 1, spool 2, and described valve body 1 one ends are provided with pressure gauge screw thread 3, and the other end is provided with pipeline screw thread 4, and spool 2 radially screw thread is installed on the valve body 1, has saved the stuffing box of common valve, and is rational in infrastructure simple; Valve body 1 is provided with damping hole 5, makes pressure gauge be connected with pipeline, has alleviated the measured medium pressure surge to adverse effects such as manometric impacts, makes pressure reading accurately convenient.
Described valve body 1 is provided with 6, one of 2 relief holes and is arranged on pressure gauge screw thread 3 ends, and another is arranged on pipeline screw thread 4 ends, in the time of in the process of dismounting pressure gauge or valve, valve is not closed completely if measured medium has pressure, and medium is at first oozed out from relief hole 6.
Also be provided with cleaning screw 7 and relieving device 8 on the valve body 1, described cleaning screw hole is connected with described damping hole 5, and relieving device 8 is connected with the cleaning screw hole.
Inside, spool 2 footpath is cone structure, and spool 2 footpaths are outside to be punching torsion bar structure.
The utility model valve is by pressure gauge screw thread 3 end direct mounting gauges, on the pipeline that pipeline screw thread 4 ends are installed in measured medium is communicated with, measured medium is communicated with pressure gauge by described damping hole 5, in the time of in the process of dismounting pressure gauge or valve, valve is not closed completely if measured medium has pressure, medium is at first oozed out from relief hole 6, avoiding continuing dismounting makes the medium ejection and hurts sb.'s feelings, twisting cleaning screw 7, lay down the valve internal pressure from relieving device 8, also can avoid the ejection of unloading process medium to hurt sb.'s feelings effectively, spanner is turned round on the parallel surface 9 of described valve body 1, can make things convenient for the installation or removal of valve.
Claims (4)
1. a pressure gauge special valve is characterized in that comprising valve body, spool, and described valve body one end is provided with the pressure gauge screw thread, and the other end is provided with the pipeline screw thread, and spool radially screw thread is installed on the valve body, and valve body is provided with damping hole, and pressure gauge is connected with pipeline.
2. pressure gauge special valve according to claim 1 is characterized in that described valve body is provided with 2 relief holes, and one is arranged on pressure gauge screw thread end, and another is arranged on pipeline screw thread end.
