Abstract
The utility model relates to an integrated three-group valve which comprises three needle valves and a main valve body. The three needle valves are connected with the inlet and the outlet of the main valve body through channels inside the three needle valves, and channels in the main valve body are communicated with one another and matched with or connected with a transmitter or directly fixed on the transmitter to form an integrated valve and to accomplish a whole control system. The whole device has reliable stability to temperature and static pressure variation and impact, and ensures that high and low pressure signals from a throttling device can simultaneously enter the high and low pressure chambers of the transmitter to protect the safety of the transmitter; and the valve has a simple structure, and is very convenient for the installation and the operation by users.
Description
Technical field
The utility model relate to a kind of transmitter input signal unlatching, close the valving with balancing run, especially three needle type valves constitute the integrated Gauge Valves device of communicating with each other by assembling.
Background technique
At present, on differential pressure transmitter, flow transmitter input signal, existence is opened, closes slow and balance is poor, the deficiency of poor sealing performance.Simultaneously, also strengthen user cost, maintenance, installation bring many unnecessary troubles to the user.
The model utility content
Existing be by the unlatching of a plurality of systems control transmitter input signal, close and balancing run, complex structure, not compact, install inconvenient, volume is big, Heavy Weight, cumbersome.The utility model provides a kind of integrated three groups of valves, and this valve not only is connected by the main-valve body by three needle type valves and forms the integrated Gauge Valves device of communicating with each other, and structure is also simple, and component interchangeability is good, maintenance and easy to use.
The technological scheme that its technical problem that solves the utility model adopts is: three needle type valves and main-valve body are formed, three needle type valves are connected with the import and export of main-valve body by the body internal channel, each passage interconnects and communicates in the main-valve body, be connected or directly be fixed on the transmitter with transmitter is supporting, constitute integrated valve, reach and finish The whole control system.
Beneficial effect is: single unit system is to temperature and static pressure changes and impact has reliable stability; guaranteed to enter the safety of the high and low voltage chamber of transmitter simultaneously with the protection transmitter from the high low pressure signal of throttling arrangement; it is simple in structure, makes things convenient for user installation and use especially.
Description of drawings
Fig. 1 is the whole front elevation of the utility model, the whole back elevation of Fig. 2 model utility, Fig. 3 model utility body internal channel figure.
Among the figure, 1, needle type valve I 2, needle type valve II 3, import 4, positioning hole 5, outlet 6, passage 7, needle type valve III
Embodiment
As shown in the figure, three needle type valves are respectively that needle type valve I (1) does high pressure valve and makees equilibrium valve with, needle type valve II (2) and make low pressure valve and use with, needle type valve III (7), be connected the integrated valve that becomes to communicate with each other by a main-valve body, three needle type valves interconnect by body internal channel (6) and import (3), outlet (5), with the supporting use of transmitter or directly be fixed on the transmitter, strengthen Security by positioning hole (4).During work, measure room from the impulse positive negative pressure that signal introduces transmitter of naming a person for a particular job, realize impulse point and measure between the room being switched on or switched off, and be switched on or switched off between the positive negative pressure measurement room, also can be used as differential pressure balance detection zero point with and make stop valve when unloading transmitter and use, when the high and low pressure opening of valves, when equilibrium valve is opened, positive negative pressure measuring chamber pressure balance; When the high and low pressure opening of valves, when equilibrium valve cut out, output end pressure corresponded to high and low pressure respectively; When equilibrium valve is opened, an opening of valves in the high and low pressure valve a, when valve cuts out, output end pressure are the pressure of open valve wherein, reach and finish The whole control system.
Claims (3)
1. integrated three groups of valves are made up of three needle type valves and main-valve body, it is characterized in that: three needle type valves are connected with the import and export of main-valve body by the body internal channel, are connected or directly are fixed on the transmitter with transmitter is supporting.
2. integrated three groups of valves according to claim 1 is characterized in that three needle type valves are installed on the main-valve body.
3. integrated three groups of valves according to claim 1 is characterized in that main-valve body internal channel communicates for being connected to each other.
