Abstract
The utility model relates to an open/close valve for a pressure gauge. The utility model is composed of a valve body with a flange end, a movable connecting screw cap which is clamped with the flange end of the valve body and is connected with the joint of a pressure gauge, a seal ring which is arranged on the flange end surface of the valve body, a tapered valve core which is arranged in the inner cavity of the valve body, and a tapered Valve core reset spring, wherein, the outlet of the valve body is arranged at the flange end of the valve body, and the tapered Valve core is provided with a cylindric head which is extended to the outlet end of the valve body. When the pressure gauge is arranged, the oil through nozzle of the pressure gauge can be pushed towards the head of the valve core, so that the Valve core can be pushed aside, and accordingly, the channel of the valve body can be opened, and oil liquid can enter the pressure gauge. When the pressure gauge is dismounted, the valve core can reset, so that the channel of the valve body can be cut off.
Description
The utility model relates to a kind of valve, particularly a kind of switch valve that is used to connect between pressure gauge and pressure-measuring point.
At present, the link between pressure gauge and pressure-measuring point mainly contains pressure meter switch, pressure gauge isolator valve and hose assembly etc.Pressure meter switch is to promote thimble by rotation hand wheel to move the break-make that realizes the pressure gauge oil circuit, and its complex structure, difficulty of processing is big, sealing part is many, and the relative position of in use manometric card and equipment room be can not determine.Separating valve is a kind of manually operated three-way slide valve, is mainly used in testing pressure applications once in a while.Its complex structure, price is more expensive, and the position setting to hydraulic fluid port during installation also has certain requirement, so application area is subjected to certain limitation.Though hose assembly is easy to use, its linkage structure complexity, price are expensive, also special fixing device need be set in addition.Above-mentioned each link is because sealing part is many, so the leakage failure rate is higher.
Task of the present utility model provides a kind of pressure meter switch valve simple in structure, easy to install, reliable.
The solution that realizes the utility model task is: the pressure meter switch valve that is provided is made up of the valve body of a flanged end, loose joint nut that one is stuck in the valve body flange end and is connected with GAUGE CONNECTOR, the poppet valve core and the poppet valve core Returnning spring that are located at the seal ring of valve body flange end face and are positioned at body cavity, wherein the outlet of valve body is located at the flange end of aforementioned valve body, and poppet valve core has a column head that extends to the valve outlet end.After this switch valve is installed on the pressure measurement pipeline, if there is not the setting pressure table, then poppet valve core is pressed to the valve seat of poppet valve core under the effect of Returnning spring and hydraulic coupling, valve channel is cut off, make fluid can not flow to valve outlet, when the setting pressure table, manometric logical oil nozzle is pushed the head of poppet valve core to, poppet valve core is backed down, thereby open valve channel, make fluid enter pressure gauge.
Compared with prior art, of the present utility model simple in structure, other part is few and be easy to processing, compares with existing pressure meter switch and can save material more than 50%.Simultaneously, install, use and keep in repair also easier.In addition, sealing part of the present utility model has only three places, is about half of existing pressure gauge link, so reliability is higher.
Accompanying drawing is a structure diagram of the present utility model.
As shown in the figure: there is a flange 7 upper end of valve body 3, and the lower end of loose joint nut 1 is stuck on the flange 7, valve body 3 and pressure gauge can be linked together by nut 1.The seal ring 2 of valve body flange end face is used for the sealing between valve body and pressure gauge.A stepped shaft inner chamber 8 is arranged in the valve body 3, and it is the internal channel of valve body 1, and its upper end is outlet, and the lower end is import.Poppet valve core 4 has a column head 9, and it extends to the outlet end of valve body 3 always so that contact with the logical oil nozzle of pressure gauge, Returnning spring 6 be positioned at poppet valve core 4 below.The underpart of valve body 3 is provided with screw thread, and it and combination seal 5 are realized being tightly connected of valve body 3 and pressure measurement pipeline together.Spool 4 is pressed to valve seat when being unkitted pressure gauge under Returnning spring 6 and oil liquid pressure effect, and valve channel is cut off.During the setting pressure table, manometric logical oil nozzle is pressed to the head upper end of spool 4, and spool 4 is moved down, and valve channel is opened, and makes fluid enter pressure gauge.If remove pressure gauge, then poppet valve core 4 is pressed to valve seat again, cuts off valve channel, so replacing and maintenance pressure table are very convenient.The occasion higher for pressure, that impact force is bigger can be provided with throttling groove at the head 9 of poppet valve core, or in the inlet of valve body 3 damping hole 10 is set, so that buffering fluid, sharply beating of the table that eases off the pressure prevents that pressure gauge from damaging.
Claims (3)
1, a kind of pressure meter switch valve, it is characterized in that forming by the valve body of a flanged end, loose joint nut that one is stuck in the valve body flange end and is connected with GAUGE CONNECTOR, the poppet valve core and the poppet valve core Returnning spring that are located at the seal ring of valve body flange end face and are positioned at body cavity, wherein the outlet of valve body is located at the flange end of aforementioned valve body, and poppet valve core has a column head that extends to the valve outlet end.
2, switch valve as claimed in claim 1 is characterized in that being provided with damping hole (10) in the inlet of valve body (3).
