Description

Urban heating balance valve convenient to maintain Technical Field The utility model relates to the technical field of balance valves, in particular to an urban heating balance valve convenient to maintain. Background The urban central heating system dynamically adjusts the flow of each branch of the pipeline network through the balance valve so as to realize the uniform distribution of heat. The existing heating balance valve mainly comprises a manual regulation type, an electric regulation type, a self-operated dynamic balance type and the like, and has the core function of controlling the sectional area of a flow passage through the matching structure of a valve core and a valve seat, thereby realizing flow balance. However, in the balance valve in the prior art, during the long-term operation and maintenance process, many problems exist, wherein the core components such as the valve core, the sealing element and the actuating mechanism of the traditional balance valve are designed in an integrated manner, the valve and the pipeline are required to be integrally disassembled for connection (such as flange bolts or welding interfaces) during replacement, so that maintenance operation is required to rely on professional tools and consumes a long time, when the sealing surface of the valve core is worn due to scale, the whole valve body is required to be disassembled, the maintenance of the valve body can be completed, the maintenance time is increased, and the overall working efficiency is influenced. In view of this, an urban heating balance valve is provided that is easy to maintain to overcome the above drawbacks. Disclosure of utility model The utility model aims to provide an urban heating balance valve convenient to maintain, so as to solve the problems in the background technology. In order to solve the technical problems, the urban heating balance valve convenient to maintain comprises a water flowing pipe and a knob and is characterized in that a lower valve body is fixedly welded above the water flowing pipe, a guide groove is formed in the outer wall of the lower valve body, a limit groove is formed in the tail end of the guide groove, an upper valve body is arranged at the bottom of the knob, an inner connecting sleeve is integrally formed in the bottom of the upper valve body, a collision table is integrally formed in the inner wall of the lower valve body, the outer diameter of the inner connecting sleeve is mutually matched with the inner diameter of the collision table, a limiting block is fixedly arranged on the outer wall of the upper valve body, and the limiting block is simultaneously matched with the guide groove and the limit groove. Further, the specific number of the guide grooves and the limit grooves is two, and the two guide grooves and the two limit grooves are distributed on the outer wall of the lower valve body in a circumferential array. Further, the specific number of the limiting blocks is two, the two limiting blocks are matched with the two guide grooves and the limiting grooves simultaneously, and the two limiting blocks are respectively positioned in the two limiting grooves in the initial state of the device. Further, a rotatable thread bush is arranged at the bottom of the inner wall of the upper valve body, a threaded rod is connected to the inner wall of the thread bush in a threaded mode, and the thread bush is fixedly connected with the knob. Further, a choke valve is fixedly connected to the bottom of the threaded rod, the concrete shape of the choke valve is a convex truncated cone, the top radius of the choke valve is the same as the radius of the inner wall of the upper valve body, the bottom radius of the choke valve is the same as the radius of the inner connecting sleeve, and a choke shell is fixedly arranged at the edge of the top surface of the choke valve. Further, a sealing ring is slidably sleeved on the outer wall of the choke valve, and an abutting spring is fixedly connected between the sealing ring and the bottom of the outer wall of the upper valve body. Further, the bottom area of the sealing ring is the same as the top area of the abutting table. Further, a circular rod is fixedly connected to the top surface of the choke valve, a circular sleeve is fixedly connected to the bottom surface of the inner wall of the upper valve body, and the circular rod is slidably arranged in the circular sleeve. Compared with the prior art, the utility model has the beneficial effects that: Through setting up the joint of stopper and spacing groove, the sealing of cooperation sealing ring and the further fixed of the elasticity of conflict spring, the completion that makes the device also can be quick under narrow and small environment such as corner is to the dismantlement of balanced valve main part, makes the maintenance and the maintenance work of balanced valve simpler.
