Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Referring to fig. 1 and 2, the present utility model provides a technical solution: a condenser for a differential pressure type throttling device comprises a differential pressure type throttling device 1, a pressure taking pipe before a valve 2, a primary valve 3, a pressure taking pipe after the valve 4, an antifreezing isolator 5 and a balance valve 6.
The top of the differential pressure type throttling device 1 is connected with one end of the pressure taking pipe 2 in front of the valve. The other end of the pre-valve pressure taking pipe 2 is connected with one end of the primary valve 3. The other end of the primary valve 3 is connected with one end of the pressure taking pipe 4 behind the valve. The side surface of the anti-freezing isolator 5 is provided with a water outlet in a downward inclined mode. The other end of the pressure taking pipe 4 behind the valve is connected with the water outlet of the anti-freezing isolator 5. The balance valve 6 is arranged on the antifreezing isolator 5. One side of the antifreezing isolator 5 is connected with a differential pressure transmitter 7.
Wherein the top of the antifreezing isolator 5 is provided with an injection hole, and the injection hole is closed by a screw.
Further, a sealing gasket is arranged between the anti-freezing isolator 5 and the differential pressure transmitter 7.
Further, the differential pressure type throttle 1 includes a high pressure port and a low pressure port. The number of the pressure taking pipe 2 before the valve, the primary valve 3, the pressure taking pipe 4 after the valve and the water outlets of the antifreezing isolator 5 are two. The front pressure taking pipe 2, the primary valve 3, the rear pressure taking pipe 4 and the water outlets of the anti-freezing isolator 5 are symmetrically arranged. One end of one of the valve front pressure taking pipes 2 is connected with the top of the differential pressure type throttling device 1, and the top of the differential pressure type throttling device is close to the high pressure port side. One end of the other pressure taking pipe 2 before the valve is connected with the top of the differential pressure type throttling device 1 near the low pressure port side.
Furthermore, the connection shape of the pre-valve pressure taking pipe 2, the primary valve 3 and the post-valve pressure taking pipe 4 is S-shaped. A bracket is arranged between the two pressure taking pipes 2 in front of the valve.
The bracket can maintain the connection shape of the pre-valve pressure taking pipe 2, the primary valve 3 and the post-valve pressure taking pipe 4 in an S shape and strengthen the pre-valve pressure taking pipe 2.
Further, the primary valve 3 is a stop valve. The shut-off valve is also called a shut-off valve, and belongs to a forced sealing type valve, so that when the valve is closed, pressure must be applied to the valve clack so as to force the sealing surface not to leak. The sealing pair of the stop valve consists of a valve clack sealing surface and a valve seat sealing surface, and the valve rod drives the valve clack to vertically move along the central line of the valve seat. The stop valve has smaller starting height in the opening and closing process, is easy to adjust the flow, is convenient to manufacture and maintain, and has wide pressure application range.
The prior art condensers are mostly cooled by passing water into a condensing tank. In addition, in the prior art, the connecting pipe and the condensing tank must be horizontally placed to ensure the upper inlet and the lower outlet of the condensing tank. The application adopts the anti-freezing isolator 5, the front pressure taking pipe 2, the primary valve 3 and the rear pressure taking pipe 4 which are integrally S-shaped to realize the situation of avoiding condensation and freezing. And the original condensing tank is eliminated, and the whole volume can be reduced under the action of not affecting the whole function.
Working principle:
The differential pressure type throttling device 1 can be replaced by different types of throttling devices according to the requirements of users, flanges at two ends are connected with on-site pipelines, and welding, flange connection, threaded connection and the like can be adopted. Closing the primary valve 3 ensures that the pre-valve pressure take-off pipe 2 and the post-valve pressure take-off pipe 4 are disconnected. And opening the balance valve 6 to ensure that the left and right pressure taking pipes 4 behind the valve of the anti-freezing isolator 5 are identical. And unscrewing injection hole screws at the upper end of the anti-freezing isolator 5, injecting anti-freezing isolating liquid by using a needle head, and enabling the anti-freezing liquid to flow into cavities connected with the left and right valve rear pressure taking pipes 4 of the anti-freezing isolator 5 along the injection holes. And when the liquid level is not falling, namely the liquid level is parallel to the injection hole of the anti-freezing isolator 5, the anti-freezing isolator is full. The balance valve 6 is closed, and the pressure taking pipes 4 behind the valve on the two sides are separated. The primary valve 3 is opened, and the excessive antifreeze flows into the pipeline along the valve rear pressure taking pipe 4, the primary valve 3, the valve front pressure taking pipe 2 and the differential pressure type throttling device 1. When the liquid level of the antifreeze fluid is flush with the joint of the pressure-taking pipe 4 behind the valve and the antifreeze isolator 5, the antifreeze isolator is prepared. When the medium with the high temperature to be detected flows through, the high temperature is blocked by the antifreeze, the temperature is not transmitted to the differential pressure transmitter 7, and the safety of the instrument is ensured. When the outside is precooled, the antifreezing solution can have good antifreezing effect, is not condensed and frozen, and can ensure that the pressure taking pipe is smooth even if the outside is not provided with a heat insulation layer and heat tracing. When the front pressure taking pipe 2, the primary valve 3 and the rear pressure taking pipe 4 are provided with accumulated liquid in the middle, the front pressure taking pipe 2, the primary valve 3 and the rear pressure taking pipe 4 are vertically arranged in an S shape, and the accumulated liquid can flow into a pipeline along the pipe wall, so that condensation and icing cannot be caused.
