In order to achieve the above purpose, the utility model discloses technical scheme as follows:

the utility model provides a take metering function's choke valve under water which the key lies in: including the installation body, be equipped with first installation cavity on the installation body to and with the liquid discharge passage and the liquid inlet channel of first installation cavity intercommunication, be equipped with throttle valve subassembly in the first installation cavity, the metering hole has been seted up on the pore wall of liquid inlet channel, the metering hole is used for the erection joint flowmeter.

Preferably, a second mounting chamber is arranged at a position of the mounting body corresponding to the metering hole, and a flow meter is assembled in the second mounting chamber.

Preferably, the mounting body is a shaft-type part, the first mounting chamber is located at the upper part of the shaft-type part, and the liquid inlet channel is located at the lower part of the shaft-type part.

Preferably, the number of the metering holes is two groups, and the metering holes are symmetrically arranged on the hole wall of the liquid inlet channel.

Preferably, the throttle valve assembly comprises a valve seat, a valve rod and a throttle driver which are sequentially arranged from bottom to top.

Preferably, the liquid inlet channel comprises a straight line section and conical sections symmetrically arranged at two ends of the straight line section.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the inside special cavity of installation body and channel design can be integrated into an organic whole with choke valve and flowmeter, directly fix the installation body and can realize choke valve and flowmeter installation on the sled body, have simplified the assembly process of choke valve and flowmeter on the sled body to sled body structure volume has been reduced.

2. The sled body is installed the back on the production tree, integrates the choke valve and the flowmeter of design, can also reduce production tree and transfer cost, transfer time and cost of maintenance etc. has very important spreading value.

Detailed Description

The present invention will be further described with reference to the following examples and accompanying drawings.

As shown in fig. 1, an underwater throttle valve with a metering function structurally comprises a mounting body 1, wherein the mounting body 1 is a shaft-type part, as can be seen from fig. 2, a first mounting cavity 1a is arranged at the upper part of the mounting body 1, a liquid inlet channel 1c is arranged at the lower part of the mounting body 1, a liquid outlet channel 1b is arranged at the side part of the mounting body 1, the liquid outlet channel 1b and the liquid inlet channel 1c are both communicated with the first mounting cavity 1a, a throttle valve assembly 2 is assembled in the first mounting cavity 1a, a metering hole 1d is formed in the hole wall of the liquid inlet channel 1c, a second mounting cavity 1e is arranged at the position corresponding to the metering hole 1d of the mounting body 1, and a flow meter is assembled in the second mounting cavity 1 e.

When the underwater throttle valve works, liquid flows through the liquid inlet passage 1c → the first installation chamber 1a → the liquid discharge passage 1b in sequence, and the flow control function of the process throttle valve assembly 2 can be realized. Meanwhile, the liquid can enter the flowmeter from the liquid inlet channel 1c → the metering hole 1d, thereby realizing the liquid metering function. The flowmeter and the throttle valve are integrated, so that the assembly process of the flowmeter and the throttle valve on the prying body can be simplified, and the structural volume of the prying body is reduced.

In this embodiment, the throttle valve assembly 2 includes a valve seat 2a, a valve rod 2b and a throttle actuator 2c that are sequentially arranged from bottom to top, and the working principle of implementing throttling is the prior art, which is not further described herein.

In the present embodiment, the flow meter connected to the metering orifice 1d may be a fiber optic flow meter, a venturi flow meter, a doppler flow meter, a magnetic resonance multiphase flow meter, or the like. Further, referring to fig. 3, the number of the metering holes 1d is two, and the two metering holes 1d are symmetrically disposed on the hole wall of the liquid inlet channel 1c, so that the flow rate can be monitored by using a pressure difference. The liquid inlet passage 1c includes a straight line segment a and tapered segments b symmetrically disposed at upper and lower ends of the straight line segment a. So designed, then help using the venturi flowmeter to carry out flow measurement.

Finally, it should be noted that the above description is only a preferred embodiment of the present invention, and those skilled in the art can make various similar representations without departing from the spirit and the scope of the present invention.
