Abstract
The utility model provides a pressure device for a plate high-grade valve type orifice plate, which comprises a hole plate seat, a sealing ring of the orifice plate seat, a lifting mechanism of a crank type orifice plate seat, an orifice plate, a big spiral plug, a safe locking valve, an emptying valve, and a valve body which is formed by the connection of an oppositely clamping plate, a valve core plate and an external connection flange. The utility model has the advantages of simple structure, easy manufacture, light weight, low cost, convenient inspection and maintenance by withdrawing the orifice plate, high pressure precision and safety. The utility model is suitable for measuring the flow quantity of media, such as natural gas, gas, etc.
Description
The utility model relates to a kind of rate-of flow and measures pressure obtaning device, particularly relates to a kind of template advanced valve type orifice plate pressure obtaning device.
Existing orifice plate pressure obtaning device is made up of valve body, top board, pressing plate, guiding valve, orifice plate seat, orifice plate seat hoisting gear, orifice plate, line oiler, equalizing valve and atmospheric valve.Valve body is complex-shaped box-shaped steel-casting structure, is divided into upper and lower valve body two partly, is formed by connecting with bolt.External flange is cast as one with following valve body.Guiding valve is a complex structure, the parts of processing precise.Orifice plate seat hoisting gear is made of the gear shaft on the upper and lower valve body, sealing socket and handgrip.Under working condition as need to change or when checking orifice plate, then open equalizing valve earlier, make upper and lower valve body equipressure after, open guiding valve, gear shaft under rotating on the valve body promotes the orifice plate seat that orifice plate is housed and enters upper valve body, closes guiding valve and equalizing valve, open the emptying body on the upper valve body, get rid of its cavity pressure, open pressing plate and cover plate on the upper valve body again, rotate the gear shaft on the upper valve body, upgrade the orifice plate seat, from upper valve body taking-up orifice plate suitable for reading.This complex structure, casting and difficulty of processing are big, the cost height, Heavy Weight, it is very inconvenient to keep in repair.
It is a kind of simple in structure, easy to maintenance that the purpose of this utility model is to provide, and the high template advanced valve type orifice plate pressure obtaning device of pressure precision.
The utility model template advanced valve type orifice plate pressure obtaning device is to realize like this, it comprises by Long Circle clamping plate, the valve body that oval ring valve central layer and external flange connect by screw, the orifice plate seat is positioned at valve body, on the orifice plate seat sealing ring is arranged, orifice plate is contained on the orifice plate seat, by orifice plate seat lift mechanism lifts, moves up and down.Hoisting gear has the crank that is connected with the orifice plate seat, the crank upper end is connected with handgrip by rotating shaft, sealed socket sleeve is in the rotating shaft and on being fixed in clamping plate, also be with the positive stop that is positioned between sealing socket and handgrip in the rotating shaft, be used for the raised position of control punch panel seat exactly, be loaded on the big plug screw on the clamping plate, safety locking valve and atmospheric valve.As checking or change orifice plate, only need to rotate handgrip in the use, promote the orifice plate seat to the fixed position, open the safety locking valve, the pressure medium between discharge sealing ring and the orifice plate seat is opened big plug screw, can take out the orifice plate on the orifice plate seat.
The advantage of the utility model template advanced valve type orifice plate pressure obtaning device is simple in structure, easily processing, and in light weight, cost is low, and the maintenance and inspection of taking-up orifice plate are very convenient, and pressure precision height, and are safe and reliable.Be applicable to the flow measurement of media such as natural gas, coal gas.
Describe the utility model embodiment in detail below in conjunction with accompanying drawing.
Fig. 1: the utility model structural representation.
The utility model template advanced valve type orifice plate pressure obtaning device comprises the valve body that is formed by connecting by screw 4 by to clamping plate 1, valve core plate 2 and external flange 3, be positioned at the orifice plate seat 5 and the sealing ring 6 of valve body, be loaded on the orifice plate 7 on the orifice plate seat 5, the crank 9 that is connected by pin 8 with orifice plate seat 5, the handgrip 11 that is connected with crank 9 by rotating shaft 10, be enclosed within the rotating shaft 10 and be fixed in the sealing socket on the clamping plate 1 12, be enclosed within the rotating shaft 10 and the positive stop 13 between sealing socket 12 and handgrip 11, be arranged on to the safety locking valve 14 on the clamping plate 1 atmospheric valve 15 and big plug screw 16.
Claims (1)
