Abstract
The utility model discloses a valve, including fixed connection's base and valve body, the inside valve rod of being connected with vice valve clack that is equipped with of valve body is equipped with disk seat and diaphragm between valve body and the base, and disk seat and diaphragm are through welding into diaphragm formula disk seat, and disk seat and main valve lamella have formed sealed of a valve. The utility model discloses an install and weld into the disk seat of diaphragm formula by diaphragm and disk seat between valve body and base, easily maintenance or directly change, and the sealed face that forms of diaphragm formula disk seat is not influenced by assembly or installation stress and it is better to make a valve seal up the effect.
Description
Technical field
The utility model relates to valve manufacture field, is specifically related to a kind of valve.
Background technique
Valve is the controlling component in fluid delivery system, there is cut-off, adjustment, water conservancy diversion, prevent the functions such as adverse current, voltage stabilizing, shunting or overflow pressure relief, very little moment of rotation is needed during operated valve, its compact structure, be easy to Operation and maintenance, be suitable for directly doing opening and closing to use, extensively should in engineering; Along with the birth of new type of valve being arranged on tank bottom at present, because tank cutoff valve arrangement is special, general Integral type valve seat structure is caused to be a difficult point in sealing.
Common valve seat is on valve body, be directly processed into i.e. integrated type valve seat, because valve body and base are bolted, in the raw very large power of the Shi Caihui that tights a bolt so integrated type valve seat stress deformation can affect sealing, also be unfavorable for maintenance simultaneously, in order to increase sealing reliability and convenient for maintaining, we need a kind of novel valve seat construction badly.
Model utility content
The purpose of this utility model is to provide a kind of good seal performance and valve for ease of maintenaince.
For reaching above-mentioned purpose, the technological scheme that the utility model adopts is: provide a kind of valve, comprise the base and valve body that are fixedly connected with, valve inner is provided with the valve rod be connected with secondary flap, valve seat and diaphragm is provided with between valve body and base, valve seat and diaphragm are by being welded into diaphragm type valve seat, and valve seat and main valve clack define the sealing surface of valve.
Optimize, main valve clack and secondary flap form secondary sealing area.
Optimize, diaphragm type valve seat is bolted between valve body and base; Diaphragm type valve seat is detachable independent valve seat.
Optimize, valve rod is provided with movement weight rod.
In sum, the utility model has the following advantages:
The utility model adopts the valve seat being welded into diaphragm type by diaphragm and valve seat be arranged between valve body and base, for ease of maintenaince or directly changes, and the sealing surface that diaphragm type valve seat is formed is not assembled or mount stress affects and makes valve seal better effects if.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the utility model valve;
Fig. 2 is the utility model valve close-up schematic view;
Wherein, 1, main valve clack; 2, valve seat; 3, base; 4, valve body; 5, diaphragm; 6, valve; 7, valve rod; 8, movement weight rod.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.
In an embodiment of the present utility model, as shown in Figure 1, provide a kind of valve, comprise the base 3 and valve body 4 that are fixedly connected with, valve body 4 inside is provided with the valve rod 7 be connected with secondary flap, be provided with valve seat 2 and diaphragm 5 between valve body 4 and base 3, valve seat 2 and diaphragm 5 are by being welded into diaphragm type valve seat, and valve seat 2 and main valve clack 1 define the sealing surface of valve 6.
Optimal enforcement example of the present utility model, main valve clack 1 and secondary flap form secondary sealing area, carry out second time sealing; Diaphragm type valve seat is bolted between valve body 4 and base 3, and diaphragm type valve seat is detachable independent valve seat; Valve rod 7 is provided with movement weight rod 8, when to movement weight rod 8 without pulling force time, the gravity of movement weight rod 8 makes valve rod 7 move downward, thus drives secondary flap and main valve clack 1 downward, the communication port of throttle down.
Diaphragm 5 is circular membranaceous elastic sensing elements.When the two sides of diaphragm is subject to the effect of different pressure (or power), diaphragm is mobile to the one side strain that pressure is low, and Shi Qi center produces the displacement becoming certain relation with pressure difference, thus valve seat 2 and base 3 are close to.And flat diaphragm can be divided into various ways by the difference of periphery whether fixed support, center whether perforate and diaphragm area distribution of force situation, wherein the most frequently used is the flat diaphragm that the uniform section circular sheet fixed by periphery is formed.Therefore, after pulling down valve body 4 during maintenance, diaphragm type valve seat for ease of maintenaince or is directly changed; During assembling, owing to being independent valve seat, sealing surface of seat is not assembled or mount stress affects and makes valve seal better effects if.
Although describe in detail embodiment of the present utility model by reference to the accompanying drawings, should not be construed as the restriction of the protection domain to this patent.In the scope described by claims, the various amendment that those skilled in the art can make without creative work and distortion still belong to the protection domain of this patent.
