Abstract
The utility model relates to field of mechanical technique; a kind of pressure transducer Protective valve specifically; comprise valve body and handle; the upper end of valve body is provided with valve rod; the outside of valve rod is arranged with protective housing, and the surface of protective housing is provided with hole, and the surface of valve body is provided with another hole; lead sealing line passes behind hole and another hole, adopts lead sealing to fix.The utility model compared with the existing technology, has designed the valve mechanism with protective equipment, thereby prevents from causing the inoperable situation of pressure transducer due to misoperation or artificial throttle down, and the accuracy of pressure transducer metering is maintained.
Description
Technical field
The utility model relates to field of mechanical technique, specifically a kind of pressure transducer Protective valve.
Background technique
Pressure transducer is an important element on gas flowmeter.In order to safeguard with easy to use, need to before pressure transducer, a valve be installed, valve, in order to cut off medium, adopts I.S.S ball valve conventionally, to be in use unlikely to medium by throttle down detachable maintaining pressure transducer, leaks.
But because the switch knob of this valve is arranged on valve, switch knob can operate arbitrarily.The in the situation that of misoperation or artificial throttle down, can make pressure transducer cisco unity malfunction and affect the accuracy of metering.
Referring to Fig. 1, pressure transducer 1 is arranged on the valve body 2 of internal-thread spherical valve, and valve body 2 is provided with handle 3, and the medium by rotatable handle 3 in just can cutting out pipeline 4, then takes off pressure transducer 1.Because internal-thread spherical valve 2 is without any protective gear, so cannot avoid the situation of misoperation or artificial throttle down.
Therefore, need to design a kind of pressure transducer Protective valve that can prevent misoperation or artificial throttle down.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of pressure transducer Protective valve that can prevent misoperation or artificial throttle down is provided.
In order to achieve the above object; the utility model has designed a kind of pressure transducer Protective valve; comprise valve body and handle; it is characterized in that: the upper end of valve body is provided with valve rod; the outside of valve rod is arranged with protective housing, and the surface of protective housing is provided with hole, and the surface of valve body is provided with another hole; lead sealing line passes behind hole and another hole, adopts lead sealing to fix.
Between described valve rod and described protective housing, adopt and be threaded.
Described valve body and described handle are separation structure.
One side of described valve body is connected with pipeline, and the opposite side of described valve body is connected with pressure transducer.
Described hole is located at the top of protective housing.
Another described hole is located at the block place of valve body.
The utility model compared with the existing technology, has designed the valve mechanism with protective equipment, thereby prevents from causing the inoperable situation of pressure transducer due to misoperation or artificial throttle down, and the accuracy of pressure transducer metering is maintained.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of prior art.
Fig. 2 is structural representation of the present utility model.
Fig. 3 is use schematic diagram of the present utility model.
Referring to Fig. 1-Fig. 3,1 is pressure transducer; 2 is valve body; 3 is handle; 4 is pipeline; 5 is lead sealing; 6 is protective housing; 7 is valve rod.
Embodiment
Now by reference to the accompanying drawings the utility model is described further.
Referring to Fig. 2, the utility model has designed a kind of pressure transducer Protective valve, comprises valve body and handle.The upper end of valve body 2 is provided with valve rod 7, and the outside of valve rod 7 is arranged with protective housing 6, and the surface of protective housing 6 is provided with hole, and the surface of valve body 2 is provided with another hole, and lead sealing line passes behind hole and another hole, adopts lead sealing 5 fixing.
In the utility model, between valve rod 7 and protective housing 6, adopt and be threaded, make protective housing 6 and valve body 1 close-coupled.
Valve body 2 is separation structure with handle 3, only, in the situation that opening protective housing 6, just handle 3 can be put up to use.
One side of valve body 2 is connected with pipeline 4, and the opposite side of valve body 2 is connected with pressure transducer 1.
Referring to Fig. 3, the utility model is when the normal work of pressure transducer 1, and protective housing 6 is spun on the screw thread of valve rod 7 and valve body 2 close contacts, on the top of protective housing 6, is provided with hole, at the block place of valve body 2, is provided with another hole, and hole and another hole are for through lead sealing line.Lead sealing 5 couples together by lead sealing bundle of lines protective housing 6 and valve body 2.
The utility model, when needs carry out throttle down operation to internal-thread spherical valve, must first be removed lead sealing 5 protective housing 6 is taken off, then bring handle 3, and handle 3 is fixed to after valve rod 7, just can operate.The utility model has prevented from causing the inoperable situation of pressure transducer 1 due to misoperation or artificial throttle down, and the accuracy of pressure transducer 1 metering is maintained.
