Abstract
The utility model provides an integrated three-valve set which comprises a valve body, two stop valves and a balance valve. The stop valves are arranged on the left side and the right side of the valve body. The balance valve is arranged on the upper side of the valve body. The integrated three-valve set further comprises two blow-down valves which are arranged on the lower side of the valve body side by side. The integrated three-valve set has the advantages that valve closing moment force is small, cutting reliability is good, a doubling seal design can enable a high-pressure side and a low-pressure side to be not prone to leakage inside and a transmitter not to be added with zero drift, outleakage of the stop valves cannot occur, and surrounding environment is not polluted. The integrated three-valve set is strong in using safety, small in size, light in weight, convenient to install, and less in maintenance workload.
Description
Technical field
The utility model belongs to valve field, especially relates to a kind of integrated three valve groups.
Background technique
Integrated three valve groups have the advantages such as simple and easy, the reliable operation of operation and Perfect in shape and function, can replace three traditional valve group equilibrium valves, support the use with differential pressure transmitter both domestic and external, are widely used in the robot control system(RCS) of electric power, chemical industry, metallurgy, light textile and scientific research department.Ride quality is reliable.It is little that unsteady cone valve cuts out moment, cuts off good reliability; The dual Seal Design makes the high and low pressure both sides both be difficult for oozing in the generation and causing transmitter to add drift, can not produce again stop valve to leak outside the pollution surrounding environment.Safety in utilization is strong.In the start stop operation process, can never export single-track overload pressure, damage transmitter.Applied widely.
Summary of the invention
Problem to be solved in the utility model provides a kind of integrated three valve groups, especially is fit to support the use with differential pressure transmitter.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of integrated three valve groups, formed by valve body, two stop valves and an equilibrium valve, described stop valve is arranged on the described valve body left and right sides, described equilibrium valve is arranged on described valve body upside, also comprise two blowdown valves, described blowdown valve is arranged side by side at the valve body downside.
Further, there is O type rubber ring the joint between described stop valve and the described valve body.
Advantage and the good effect that the utlity model has are: owing to adopt technique scheme, it is little that valve cuts out moment, cuts off good reliability; The dual Seal Design makes the high and low pressure both sides both be difficult for oozing in the generation and causing transmitter to add drift, can not produce again stop valve to leak outside the pollution surrounding environment; Safety in utilization is strong, and volume is little, and is lightweight, easy for installation, and maintenance workload is few.
Description of drawings
Fig. 1 is structural representation of the present utility model
Among the figure:
1, valve body 2, stop valve 3, equilibrium valve
4, blowdown valve
Embodiment
As shown in Figure 1, the utility model is a kind of integrated three valve groups, formed by valve body 1, two stop valves 2 and an equilibrium valve 3, described stop valve 2 is arranged on described valve body 1 left and right sides, described equilibrium valve 3 is arranged on described valve body 1 upside, also comprise two blowdown valves 4, described blowdown valve 4 is arranged side by side at valve body 1 downside.
There is O type rubber ring the joint between described stop valve 2 and the described valve body 1.
The working procedure of this example:
When three valve groups came into operation: original state was assumed to the high and low pressure stop valve and equilibrium valve all closes.
1, checks whether pipeline connects normally sewage draining exit shutoff: prevent dielectric leakage;
2, open equilibrium valve: make simultaneously pressurized of high and low pressure side;
3, opening high pressure stop valve: receiving process pipeline pressure;
4, close equilibrium valve: both sides are subjected to malleation;
5, open low-pressure shutoff valve: enter measuring state.Annotate: when opening the high and low pressure stop valve, should unclamp first the connection of the rear affirmation of circle instrument side and after leaking, again valve all be opened.
When instrument was stopped using: original state was that the high and low pressure stop valve is opened, and equilibrium valve closes.
1, closes low-pressure shutoff valve;
2, open equilibrium valve;
3, close high-low voltage stop valve;
4, close equilibrium valve.
More than an embodiment of the present utility model is had been described in detail, but described content only is preferred embodiment of the present utility model, can not be considered to be used to limiting practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the present utility model.
Claims (2)
