Abstract
A device for guiding out pressure in a compressor cylinder mainly solves the problem that: the pressure is tapped by directly opening a hole on the compressor cylinder, easily resulting into variation in cylinder strength. The device is characterized in that: a connection nut (3), a pressure cap (4), a guide pipe (5), a compression nut (6), a gas inlet valve cover (7) and a connection valve cover nut (8) are sequentially connected with the external part of a connection bolt (2), wherein a center hole is formed on the guide pipe (5), and communicated with a fine through hole on the connection bolt (2); sealing rings are respectively arranged between the guide pipe (5) and the connection valve cover nut (8), and between the gas inlet valve cover (7) and the connection valve cover nut (8); a valve (9) with a joint (10) and a sensor (11) is connected with the upper part of the gas inlet valve cover (7), and a gas flow channel inlet in the valve (9) is communicated with the center hole in the guide pipe (5). The structure of the device is simple and the cylinder is easily prevented from being damaged on a compressor.
Description
Technical field
The utility model relates to a kind of device for the compresser cylinder internal pressure is drawn.
Background technology
The Changing Pattern of gaseous tension in the cylinder was the true record of compresser cylinder some work situation when the compresser cylinder load-position diagram had reflected compressor piston is in each position in a working cycle.When the cylinder portion of compressor, when breaking down such as air valve, piston ring, stuffing-box etc., load-position diagram will demonstrate a certain special shape.By identifying difform index map, just can make accurately diagnosis to the fault that the compresser cylinder part occurs.Therefore, to draw load-position diagram be that the compressor operating operating mode is monitored a kind of effective method with fault diagnosis to admission compresser cylinder internal pressure.Existing two kinds of method test compression machine inner pressure of air cylinder.The one, the indirect method of measurement is namely analyzed the inner pressure of air cylinder situation of change by indirect measuring-signal.The deficiency of the method is the impact that is subject to the intermediate link disturbing factor, and measuring accuracy is low, and practical application effect is undesirable.The 2nd, the direct method of measurement is normally in cylinder wall perforate pressure.The deficiency of the method is to destroy air cylinder structure, reduces cylinder intensity, and perforate technology and equipment Requirement are high, careless slightlyly just may damage whole cylinder, has a big risk.
Summary of the invention
In order to solve the technical matters of mentioning in the background technology, the utility model provides a kind of compresser cylinder internal pressure ejector, and this kind ejector is simple in structure, is easy to realize and avoided compressor casing intensity is caused damage at compressor.Utilize this device can accurately gather the interior pressure data of cylinder, make test result can well reflect the interior working condition of compresser cylinder.
The technical solution of the utility model is: this kind compresser cylinder internal pressure ejector, comprise a coupling bolt that can be connected with compressor valve, its unique distinction is: have thin through hole on the described coupling bolt, outside coupling bolt, be connected with attaching nut, pressure cap, conduit, gland nut, air inlet valve gap and connection valve box nut in turn, wherein, have center pit on the conduit, be connected with thin through hole on the coupling bolt; Between conduit and the connection valve box nut, be equipped with O-ring seal between air inlet valve gap and the connection valve box nut; Above described air inlet valve gap, be connected with one with the valve of joint and sensor, the interior center pit of the gas channel entrance in the described valve and conduit is connected.
The utlity model has following beneficial effect: utilize this device when detected pressures, pressure transducer is connected with joint, and opens valve, and during detected pressures, valve closing does not unload lower pressure sensor, and with plug that interface protection is good.In this device the pressure deriving structure being divided into two parts is the installations that both made things convenient for air valve, also can reduce the impact on the compressor redundant gap volume as far as possible.This apparatus structure is simple, can avoid on the compresser cylinder cylinder body directly perforate, without damage, and processes easy for installationly to cylinder body, seals simple and easyly, and versatility is good, and promotional value is arranged.
Description of drawings:
Fig. 1 is structure cut-open view of the present utility model.
1-compressor valve among the figure, 2-coupling bolt, 3-attaching nut, 4-pressure cap, 5-conduit, 6-gland nut, 7-air inlet valve gap, 8-connection valve box nut, 9-valve, 10-joint, 11-sensor.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By shown in Figure 1, this kind compresser cylinder internal pressure ejector, comprise a coupling bolt 2 that can be connected with compressor valve 1, its unique distinction is: have thin through hole on the described coupling bolt 2, be connected with attaching nut 3, pressure cap 4, conduit 5, gland nut 6, air inlet valve gap 7 and connection valve box nut 8 in turn outside coupling bolt 2.Wherein, have center pit on the conduit 5, be connected with thin through hole on the coupling bolt 2; Between conduit 5 and the connection valve box nut 8, be equipped with O-ring seal between air inlet valve gap 7 and the connection valve box nut 8; Above described air inlet valve gap 7, be connected with one with the valve 9 of joint 10 and sensor 11, the gas channel entrance in the described valve 9 and conduit 5 interior center pits are connected.
By above description as can be known, compresser cylinder internal pressure ejector is comprised of two parts, a part directly and the coupling bolt on the air valve be threaded connection, formed by attaching nut and pressure cap, wherein between coupling bolt and the attaching nut, be provided with O-ring seal between attaching nut and the pressure cap; Another part is fixed on gas admittance valve and covers, and is connected in sequence by conduit, gland nut, connection valve box nut, valve, joint and sensor, wherein between conduit and the connection valve box nut, is provided with O-ring seal between air inlet valve gap and the connection valve box nut.
During use, two parts dock by conduit and attaching nut up and down, and seal by O-ring seal.Pressure in the cylinder is drawn by the pore, catheter center hole, valve and the joint that are processed at air valve coupling bolt center, and detects the pressure of gas in the cylinder by the pressure transducer that is connected with joint.
Utilize this device when detected pressures, pressure transducer is connected with joint, and opens valve, and during detected pressures, valve closing does not unload lower pressure sensor, and with plug that interface protection is good.
