Description

Inclined balance valve
Technical field
The invention belongs to valve technology field, relate to a kind of equilibrium valve, particularly a kind of inclined balance valve.
Background technique
At present, in heat supply, heating and the air-conditioning system, often there is the problem of hydraulic misadjustment in the water pipe pipe network system, both when the actual motion of system, flow through each building building or the water flow and the designing requirement of end equipment be not inconsistent.For solving the problem of water conservancy imbalance, the designer adopts valve to realize hydraulic equilibrium.But because the aperture and the flow of common valve are fast katal, not flow indication makes the work complexity of adjustment loaded down with trivial details, is difficult to realize.
For further improving these shortcomings, Chinese patent application number is 91210079.6 to disclose a kind of " number lock equilibrium valve ", this equilibrium valve is made of valve body, valve gap, valve rod and valve plug, is equipped with on the circle seat on the valve gap that digital calibration dish, circle pedestal one side are equipped with the quantity gear, opposite side is provided with lock pin.Because the valve rod of this equilibrium valve is obliquely installed, valve gap also is obliquely installed, and the digital calibration dish that is arranged on the valve gap also can tilt, and user's inconvenience is observed; Secondly, owing to be being obliquely installed of spool, spool can in use be under pressure and swing poor stability; In addition, the pressure test point is separately positioned on the two ends of water intake and water outlet, the inconvenience of measurement, simultaneously-measured error is higher.
The equilibrium valve of other tilting also all is separately positioned on the pressure test point two ends of water intake and water outlet, has above-mentioned problem equally.
Summary of the invention
The objective of the invention is the above-mentioned problem that exists at existing inclined balance valve, the inclined balance valve that a kind of measuring accuracy height, stable performance are good, be convenient to observed reading is provided.
Purpose of the present invention can realize by following technical proposal: a kind of inclined balance valve, comprise handwheel, valve body with water-inlet cavity and water chamber, be obliquely installed spool and valve rod in valve body, this spool is connected with an end axial restraint of valve rod, the other end of valve rod passes valve body and circumferentially fixedlys connected with handwheel, be connected with screw thread between valve rod and the valve body, on valve body, be provided with two testing tubes, wherein a testing tube is connected with water-inlet cavity, it is characterized in that, be provided with lumen between inherent water-inlet cavity of described valve body and the water chamber, another root testing tube is connected with lumen, in lumen, be provided with sealing surface, above-mentioned spool is plugged in the lumen and can contacts with sealing surface, and valve rod is provided with the indicator of opening of the vertical bar shaped that is used to represent the spool open degree.
The spool and the valve rod of this inclined balance valve all are obliquely installed, and the sealing surface in the lumen also is obliquely installed accordingly, and spool can contact and form sealing with sealing surface, among the application with the degree of spool and sealing surface unlatching the spool open degree.During use, pressure or temperature test instrument are connected in the testing tube, measure that the comparative illustration book according to pressure difference and spool open degree comes the regulating spool open degree after the pressure difference.During adjusting, rotate handwheel, because handwheel is circumferentially to fixedly connected with valve rod, valve rod is along with handwheel rotates together, valve rod simultaneously with valve body for being threaded, along with the rotation of handwheel, valve rod can axially moving around along valve rod, and also can moving, thereby control spool open degree along with valve rod with the spool of valve rod axial restraint.Water-inlet cavity has different pressure differences with lumen, and two testing tubes are connected respectively to water-inlet cavity and lumen, can improve the precision of test, can make the compact structure of testing tube simultaneously, and occupation space is little.
