Abstract
The utility model relates to a valve gate, especially a self-actuated flow rate control valve with direct viewing flow rate scale indicating dial and magnetic lock function, which solves the problem that the flow rate indicating scale of the flow rate control valve gate is uneasy to observe and lock, and the flow rate being randomly adjusted in prior art. The utility model comprises a magnetic lock combined with a self-actuated flow rate control valve with rotating rod, a magnetic lock body and a magnetic lock cap. The self-actuated flow rate control valve rotating rod is firmly connected with a lock socket with groove and flow rate indicating disc. The lock socket is plugged into the magnetic lock and the flow rate indicating disc is fixed on the valve cover. The utility model has the advantage that, first, effective concentrated heating supply is realized and the flow rate control valve gate is randomly opened or closed in family splitting management, which thoroughly solves the problem of charging in heating supply industry. Second, quantity management of the flow rate is realized to distribute the flow rate according to the needs.
Description
Technical field
The utility model relates to a kind of valve, particularly a kind of flow scale index dish and the self-operated flow control valve with magnetic locking function very intuitively of having.
Background technique
Quickening along with Urbanization in China, urban building is more and more, more and more intensive, because traditional heating network near-thermal is far cold, upper heat and lower cold, high energy consumption, low-quality heat supply situation have caused the contradiction between heat supply unit and the user continuous, the charge difficulty is big, and central heat supply has become a kind of development trend.Resident's heating just progressively develops to the direction of central heat supply, household management, and the control of branch family is exactly that each household is installed a self-operated flow control valve, makes heating enterprise directly in the face of the user.Whom carries out whom pays the fees, do not pay the fees and just not open the intelligent management pattern of bolt, so both helped solving the problem of long-term puzzlement heating industry difficult charge, can guarantee that again the resident can not be subjected to " involving in a criminal case " because of the individual user is late for paying the fees with heat.At present, several flow control valves are arranged on the market, but shortcoming is that the flow scale indication is not obvious, directly perceived, and does not have magnetic locking function, be not easy to observe flow and control and management.Especially caused great difficulty to metering management.If other valve and the flow control valve that closes function with lock is used, can address the above problem, but strengthen cost thus, and because the lengthening of pipeline makes it to be subjected to the restriction in mounting point and space.
Summary of the invention
Flow control valve valve flow indicating graduation is not easy to observe and locking control the utility model in the prior art in order to solve, but problems such as flow regulated at will provide a kind of self-operated flow control valve that has flow scale indication and locking function with flow control valve and locking valve dual functions.
The utility model is to adopt following technological scheme to realize: the self-operated flow control valve of indication of band flow scale and locking function comprises self-operated flow control valve that dwang is installed and the magnetic lock that is made of magnetic lock body, magnetic lock nut.Stretch out the locking cover of fixedly connected band groove and flow indicator panel on the dwang of self-operated flow control valve valve gap, the locking cover inserts in the magnetic lock body, and flow indicator panel lower surface is fixed in valve gap.
At first locking cover special, that have the concavity draw-in groove is fixed together with the flow indicator panel that has the flow indicating graduation, and is inserted in simultaneously on the dwang that plays the manual tune flow in the flow control valve, locking cover and dwang are fixed with elastic cylindrical pin.At this moment the rotation by dwang drives the flow indicator panel and rotates, and by on the valve gap fixedly indicating arrow regulate the size of flow accurate and visually or open and close flow control valve.After the setting, with the magnetic lock body valve pocket dwang and locking cover are covered, being provided with locking device (steel ball of lock body inner ring is put corresponding with it groove by locking and blocks) stranger between magnetic lock body and the locking cover can't open.When needing unlatching or carrying out Flow-rate adjustment, must there be the professional workforce that the magnetic lock cap sleeve is gone into outside the magnetic lock body (the magnet mark on the lock nut to be aimed at the lock body inner magnet, because homopolarity produces repulsion relatively), magnetic lock body and locking cover is separated, can carry out.Self-operated flow control valve can or actual require to set flow according to design, the pressure of have more than needed of elimination system automatically, and the maintenance constant flow is constant, has thoroughly solved the drawback of pipe network hydraulic misadjustment, has improved heating quality, has realized the quantitative management of flow.Not only fundamentally eliminate the phenomenon of " uneven in temperature ", the more important thing is the effect that saves heat, economize on electricity, water saving reduction heat cost of having played.
The beneficial effects of the utility model are as follows: 1, effectively manage central heat supply, the random keying of flow control valve in the household management thoroughly solves the problem of heating industry difficult charge; 2, realize the quantitative management of flow, make the form distribution according to need of energy with flow.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the schematic representation of flow indicator panel.
Among the figure, 1-self-operated flow control valve, 2-dwang, 3-flow indicator panel, 4-locking cover, 5-magnetic lock body, 6-magnetic lock nut (key), 7-valve gap.
Embodiment
In conjunction with the accompanying drawings mode of execution of the present utility model is further described, present embodiment is to be used for illustrating of the present utility model, rather than the utility model is done any restriction.
The self-operated flow control valve that has flow scale indication and locking function comprises self-operated flow control valve 1, dwang 2, flow indicator panel 3, locking cover 4, magnetic lock body 5, magnetic lock nut 6, valve gap 7.The flow indicator panel 3 that will have the flow indicating graduation is fixed on the locking cover 4 special, that have the concavity draw-in groove, and place on the valve gap 7 by the dwang 2 of manual tune flow in the flow control valve 1, with elastic cylindrical pin that locking cover 4 is fixing with dwang 2, a fixing indicating arrow is arranged on the valve gap 7, when rotating dwang 2, can drive locking cover 4 and flow indicator panel 3 and rotate together, at this moment, by indicating arrow, can know the flow size of passing through in the valve, accurately adjust flow value.After flow is set up magnetic lock body 5 is covered on outside the locking cover 4, make magnetic lock body inner ring steel ball be put corresponding with it groove and block, with dwang 2 lockings of manual tune flow by locking.When needs are opened lock, by the professional workforce mark on the magnetic lock nut 6 is aimed at the mark on the magnetic lock body 5, be placed in outside the magnetic lock body 5, pressing down the back gently enters in the opening groove of outer ring the steel ball of lock body inner ring by the repulsion that the two blocks of magnet staggered relatively of homopolarity in the lock produce, lock body and locking cover 4 are thrown off, and lock is opened.Magnetic lock nut 6 is administered by the special messenger, and the stranger can't open and close flow control valve.
