Detailed Description

The following detailed description of the embodiments of the present invention is made with reference to the accompanying drawings, so that the technical solution of the present invention can be more easily understood and grasped.

Example (b):

referring to fig. 1 to 5, the present embodiment provides a water-gas separation single-cylinder internal-pushing type clamp meter, which is mainly used for solving the problem that in the operation process of the clamp meter, insufficient water-gas separation occurs inside a cylinder, and a sealing gasket is easily damaged.

Specifically, because the meter clamping device clamps the water meter and leads water after clamping, the water meter is verified, when the water-gas separation is insufficient, the air in the water pipe can generate reading errors on the water meter, and further the detection result can be influenced, meanwhile, the double-cylinder meter clamping device can not ensure the complete equivalent extension and retraction of the two cylinders in the operation of the cylinders, further the sealing washer can be damaged in different degrees, the service life of the sealing washer can be reduced, the performance of the sealing washer can be influenced, the water-gas separation effect can be influenced, further the subsequent water meter verification can be influenced, and in order to solve the problems, the embodiment of the invention has the advantages that the water meter clamping device can be used for clamping the water meter and can be used for detecting the water meter; a single-cylinder inner-pushing type meter clamping device for water-gas separation is characterized in that an inner-pushing-through pipe 4 extending out of a cylinder 1 is slidably arranged in a running cavity 11, a water inlet pipe 3 is fixedly arranged at one end of the cylinder 1, the water inlet pipe 3 is sleeved on the periphery of the inner-pushing-through pipe 4, a sealing mechanism is arranged between the water inlet pipe 3 and the cylinder 1, a piston 42 is fixedly arranged on one section of the outer periphery of the running cavity 11 of the inner-pushing-through pipe 4, and the piston 42 is slidably connected in the running cavity 11;

the operation of having passed through cylinder 1 has guaranteed that interior thrust pipe 4 in the double-layered table ware can effectual flexible, and then has reached the centre gripping and the switch-on to the water gauge, and then prepare for the examination of follow-up water gauge, it completely isolated to have guaranteed simultaneously through sealing mechanism between in 11 and the external world of operation chamber, and then reached the purpose of aqueous vapor separation, because single cylinder 1 operation, and then reached and made the skew condition that causes seal assembly when pressing from both sides the table ware operation reduce to the minimum, and then can effectually prevent the problem of 11 gas leakage of operation chamber and intaking.

It should be noted that, in order to prevent the water of the water inlet pipe from leaking outside and prevent the leaked water from entering the operation cavity, in order to solve such problems, the sealing mechanism includes a fixing plate 2, a sealing groove formed on one end surface of the fixing plate 2, and a sealing ring 5 abutting against the sealing groove, and the inner push-through pipe 4 is slidably connected to the end surface of the inner side of the sealing ring 5; when interior thrust pipe 4 slides in inlet tube 3, can make water constantly flow, and then can flow on the end wall along with interior thrust pipe 4, when water passes through the joint clearance and outwards flows, can receive sealing ring 5's influence, and then guaranteed the unable external purpose that flows of water in the inlet tube 3, also make water simultaneously can't flow into operation chamber 11 along with interior thrust pipe 4 in, and then reached the purpose of separation of water.

In addition, sealing ring 5 is close to water stopping groove has been seted up in 3 lateral surfaces of inlet tube, water stopping inslot sets firmly and is used for preventing water stopping gasket 511 that interior thrust pipe 4 leaked, water stopping gasket can guarantee that the water in the inlet tube flows to the outside, and then has guaranteed the purpose of aqueous vapor separation.

Meanwhile, when the inner push-through pipe 4 needs to be driven to stretch and move, the air cylinder 1 starts to operate at the moment, the air starts to be introduced into the operation cavity 11, one side of the piston 42 starts to enter air, and then the piston 42 is driven to slide in the operation cavity 11, so that the purpose of driving the inner push-through pipe 4 to move is achieved, and meanwhile the purpose of separating the operation cavity 11 from outside water and air can be guaranteed.

Referring to fig. 2 and 3, since the inner push-through pipe slides in the operation cavity and is communicated with the outside, in order to prevent water from entering the operation cavity or being connected with the outside air, and further affect the operation of the meter clamping device, in order to solve such problems, an air stop groove is formed in one side of the sealing ring 5 away from the water inlet pipe 3, and an air stop gasket 52 for preventing the operation cavity 11 from being communicated with the outside is fixedly arranged in the air stop groove; because one end of the sealing ring 5 is abutted against one end of the cylinder 1, when the air in the operation cavity 11 needs to be communicated with the outside, the air can be blocked by the air stop gasket 52 in the sealing ring 5, and the problem of preventing the air from entering or leaking from the operation cavity 11 is solved.

It should be further noted that, in order to prevent the problem, the other side of the operating cavity 11 is communicated with the outside, a leakproof gasket 43 is slidably connected to the periphery of one end of the inner thrust pipe 4, which is far away from the water inlet pipe 3, one end of the leakproof gasket 43 is fixedly arranged on an end surface of the cylinder 1, which is far away from the water inlet pipe 3, and the purpose of separating water from air in the operating cavity 11 and outside can be effectively ensured through the leakproof gasket 43.

Referring to fig. 2 to 4, in the process of calibrating the water meter, water needs to be introduced to drive a pointer of the water meter to rotate, so that the purpose of calibration is achieved, and water in a water inlet pipe needs to be introduced into the water meter; when the water in the water inlet pipe 3 continuously flows and then flows into the inner push-through pipe 4, one end of the inner push-through pipe 4 is connected to the water meter connector, so that the purpose of leading water into the water meter is achieved, and further preparation is made for subsequent water meter verification.

It should be noted that, one end of the water inlet pipe is provided with a power mechanism, the power mechanism may include a water pump, a motor and other power sources, and the power mechanism can bring water into the water inlet pipe 3.

Above only the typical example of the utility model discloses, in addition, the utility model discloses can also have other multiple concrete implementation manners, all adopt the technical scheme that equivalent replacement or equivalent transform formed, all fall in the utility model discloses the scope of claiming.
